22.067 | enhanced Multi Level Precedence and Pre-emption service (eMLPP); Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.067/22067-i01.zip | The present document specifies the stage 1 description of the enhanced Multi‑Level Precedence and Pre‑emption Service (eMLPP). This service has two parts: precedence and pre‑emption. Precedence involves assigning a priority level to a call in combination with fast call set‑up. Pre‑emption involves the seizing of resources, which are in use by a call of a lower precedence, by a higher level precedence call in the absence of idle resources. Pre‑emption can also involve the disconnection of an on‑going call of lower precedence to accept an incoming call of higher precedence.
The eMLPP service is provided as a network operator's option to a domain of a network. The domain can be the whole network or a subset of the network. The eMLPP service applies to all network resources in the domain that is in common use. The eMLPP service is applicable to all mobile stations in the domain with all or some mobile stations having a respective subscription assigning precedence according to the eMLPP service.
eMLPP is a supplementary service and shall be provided to a subscriber for all basic services subscribed to and for which eMLPP applies.
The service is described from the service subscriber's and user's point of view, in particular:
‑ the procedure for normal operation with successful outcome;
‑ the action to be taken in exceptional circumstances;
‑ the interaction with other services and features.
The present document does not deal with the Man‑Machine Interface (MMI) requirements, but makes reference to the appropriate specifications.
The present document is applicable to teleservices 1x and 6x and to all bearer services used in a mobile network if eMLPP is provided. Any interaction with other services and/or networks not dealt with in clauses 8 or 9 are outside the scope of the present document. |
22.071 | Location Services (LCS); Service description; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.071/22071-i01.zip | This document provides the Stage One description of Location Services (LCS). A Stage One description provides an overall service description, primarily from the service subscriber's and user's points of view, but not dealing with the details of the Man Machine Interface (MMI). This TS includes information applicable to network operators, service providers and terminal, base station system, switch, and data base manufacturers.
NOTE: Location Services may be considered as a network provided enabling technology consisting of standardized service capabilities which enable the provision of location-based applications. These applications may be service provider specific. The description of the numerous and varied possible location applications which are enabled by this technology are outside the scope of this specification. However, clarifying examples of how the functionality being specified may be used to provide specific location services is included in various sections of the specification.
This document provides core requirements to an extent sufficient to derive a complete definition of location services at the service level. However, the present document also provides additional requirements which may suggest in a non-normative manner certain ways the system may be implemented to support location services.
LCS can be offered without subscription to basic telecommunication services. LCS is available to the following categories of LCS clients:
Value Added Services LCS Clients – use LCS to support various value-added services. These clients can include UE subscribers as well as non-subscribers to other services.
PLMN Operator LCS Clients – use LCS to enhance or support certain O&M related tasks, supplementary services, IN related services and bearer services and teleservices.
Emergency Services LCS Clients – use LCS to enhance support for emergency calls from subscribers.
Lawful Intercept LCS Clients – use LCS to support various legally required or sanctioned services.
LCS is applicable to any target UE whether or not the UE supports LCS, but with restrictions on choice of positioning method or notification of a location request to the UE user when LCS or individual positioning methods, respectively, are not supported by the UE.
LCS is being developed in phases with enhancements added in 3GPP releases.

22.072 | Call Deflection (CD) service description; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.072/22072-i01.zip | Call Deflection (CD) enables the served mobile subscriber to respond to an incoming call offered by the network by requesting redirection of this call to another number specified in the response. The CD supplementary service can only be invoked before the connection is established by the served mobile subscriber, i.e. in response to the offered call, or during the period that the served subscriber is being informed of the call. The served subscriber’s ability to originate calls is unaffected by the CD supplementary service. |
22.076 | Noise suppression for the AMR codec; Service description; Stage 1 | TS | 18.0.0 | S4 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.076/22076-i00.zip | The present document specifies the stage 1 description for the Noise Suppression feature for the AMR codec which enhances the input speech signal corrupted by acoustic noise. In analogy with ITU-T Recommendations I.130 [1], Stage 1 is an overall service description, from the service subscriber's and user's standpoints, that views the network as a single entity which provides services to the user. |
22.078 | Customised Applications for Mobile network Enhanced Logic (CAMEL); Service description; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.078/22078-i01.zip | This standard specifies the stage 1 description for the CAMEL feature (Customised Applications for Mobile network Enhanced Logic) which provides the mechanisms to support services consistently independently of the serving network. The CAMEL features shall facilitate service control of operator specific services external from the serving PLMN. The CAMEL feature is a network feature and not a supplementary service. It is a tool to help the network operator to provide the subscribers with the operator specific services even when roaming outside the HPLMN.
If an IPLMN or VPLMN supports CAMEL Phase 4, it shall also provide the functionality of all previous CAMEL phases.
Phase 4 network signalling shall support interworking with CAMEL Phases 3 and 2.
The CAMEL feature is applicable
- To mobile originated and mobile terminated call related activities;
- To supplementary service invocations;
- To SMS MO, to GPRS sessions and PDP contexts, to the control of HLR subscriber data, to the control of network signalling load.
The mechanism described addresses especially the need for information exchange among the VPLMN, HPLMN and the CAMEL Service Environment (CSE) for support of such operator specific services. Any user procedures for operator specific services are outside the scope of this standard.
This specification describes the interactions between the functions of the VPLMN, HPLMN, IPLMN and the CSE.
The second phase of CAMEL enhances the capabilities of phase 1 where the following capabilities have been added:
- Additional event detection points;
- Interaction between a user and a service using announcements, voice prompting and information collection via in band interaction or USSD interaction;
- Control of call duration and transfer of Advice of Charge Information to the mobile station;
- The CSE can be informed about the invocation of the supplementary services ECT, CD and MPTY;
- For easier post-processing, charging information from a serving node can be integrated in normal call records.
The third phase of CAMEL enhances the capabilities of phase 2. The following capabilities are added:
- Support of facilities to avoid overload;
- Capabilities to support Dialled Services;
- Capabilities to handle mobility events, such as (Not-)reachability and roaming;
- Control of GPRS sessions and PDP contexts;
- Control of mobile originating SMS through both circuit switched and packet switched serving network entities.
- Interworking with SoLSA. (Support of Localised Service Area). Support for this interworking is optional.
- The CSE can be informed about the invocation of the supplementary services CCBS.
Detailed information is given in the respective sections.
The fourth phase of CAMEL enhances the capabilities of phase 3. The following capabilities are added:
- CAMEL support for Optimal Routeing of circuit-switched mobile-to-mobile calls;
- The capability for the CSE to create additional parties in an existing call;
- The capability for the CSE to create a new call unrelated to any other existing call;
- Capabilities for the enhanced handling of call party connections;
- The capability for the CSE to control sessions in the IP Multimedia Subsystem.
- Enhanced CSE capability for Dialled Services.
- The capability to report basic service changes during ongoing call.
- The CSE capability to select between preferred and less preferred bearer service.
- The capability for the CSE to control trunk originated calls.
- The capability for the CSE to request additional dialled digits.
With CAMEL Phase 4, it is possible that only a limited subset of the new functionalities is supported, in addition to the complete support of CAMEL Phase 3. |
22.079 | Support of Optimal Routeing (SOR); Service definition; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.079/22079-i01.zip | This Stage 1 description of the first phase of Support of Optimal Routing (SOR):
- compiles the basic service requirements for SOR;
- describes the interactions for Supplementary Services (SS) in order to cater for SOR;
- refers to modifications to network features required by SOR.
This specification does not address the following:
- There is no need for optimisation of the routing of calls originally directed to a fixed network subscriber, because the physical address of a fixed network terminating line cannot differ from its logical address.
- SOR in non-PLMNs is not a subject of this TS, but might be possible by bilateral arrangement between PLMN operators and those non-PLMN operators.
The purpose of SOR is to reduce the number of unnecessary inter-PLMN call legs.
The first phase of SOR applies to:
- OR for the benefit of the B party i.e. Mobile terminated calls with late call forwarding to the home or visited country (scenarios 1 and 2),
and optionally;
- OR for the benefit of the A party, e.g. Mobile to mobile calls where both mobile subscribers are in the same country (scenarios 3 to 10).
The complete set of scenarios included in the phase 1 of OR is presented in the paragraph for normal procedures. All other scenarios are excluded from Phase 1 of OR.
Note that Optimal Routing is applicable to national roaming situations, that is to calls directed to a mobile subscriber roaming in her home country, but registered in a PLMN different from her HPLMN.
All further call scenarios, including multiple call forwarding, are left to subsequent phases of SOR. Subsequent phases of SOR shall be backwards compatible with this first phase. |
22.081 | Line Identification supplementary services; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.081/22081-i01.zip | The present document describes the Supplementary Services belonging to the group Line Identification Supplementary Services.
The general aspects, including definitions and recommended provision, of the description of the Supplementary Services are given in 3GPP TS 22.004.
The group of Line Identification Supplementary Services is divided into the following four Supplementary Services:
CLIP - Calling line identification presentation (clause 1);
CLIR - Calling line identification restriction (clause 2);
COLP - Connected line identification presentation (clause 3);
COLR - Connected line identification restriction (clause 4).
Definition of line identity: The line identity is made up of a number of information units:
- the subscriber's national ISDN/MSISDN number (MSISDN number is the number stored in the VLR);
- the country code;
- optionally, subaddress information. The PLMN cannot be responsible for the content of this subaddress. (For definition of the subaddress see ITU-T Recommendation E.164 [3] subclause 11.2).
In a full ISDN environment, the line identity shall include all the address information necessary to unambiguously identify a subscriber.
The calling line identity is the line identity of the calling party.
The connected line identity is the line identity of the connected party.
If for the line identity of the calling party or the connected party additional line identification is received (additional calling party/connected party number) in a PLMN this additional line identification shall be used for the presentation purpose of the line identification presentation services.
Definition of Presentation and Screening Indicators: In addition to or instead of the line identity, the network may give a Presentation Indicator (PI) and/or a Screening Indicator (SI) to the served subscriber. The following information may be given:
- Presentation Indicator showing:
a) presentation allowed, or
b) presentation restricted, or
c) number not available due to interworking;
If Presentation Indicator is set to "Presentation Restricted", then the MS can get additional information on the Cause of no CLI, if provided by the network.
The Cause of no CLI value may be one of the following :
- Unavailable
- reject by user
- interaction with other services
- coin line / pay phone
- Screening Indicator showing:
a) user provided, verified and passed, or
b) user provided, not screened, or
c) network provided.
If the line identity is that of a PLMN subscriber, then:
the national number and the country code shall always be provided by the network;
the subaddress shall only be included if it is provided by the user (or user equipment);
the screening indicator shall indicate "network provided". |
22.082 | Call Forwarding (CF) Supplementary Services; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.082/22082-i01.zip | This specification describes the supplementary services belonging to the group CALL OFFERING SUPPLEMENTARY SERVICES.
The general aspects, including definitions and recommended provision, of the description of the supplementary services are given in specification 3TS 22.004.
The group of supplementary services CALL OFFERING SUPPLEMENTARY SERVICES is divided into four different supplementary services:
- Call forwarding unconditional (section 1);
- Call forwarding on mobile subscriber busy (section 2);
- Call forwarding on no reply (section 3);
- Call forwarding on mobile subscriber not reachable (section 4).
Indication of active Call forwarding supplementary service.
An indication that a Call forwarding service is currently active and operative on a number will be given to the forwarding party each time an outgoing call is made. There will be one indication for Unconditional call forwarding and another common indication for the Conditional call forwarding services.
Note on the use of the forwarded-to number at registration.
If the forwarded-to number is a number in the HPLMN country, it may be entered by the served mobile subscriber in three different formats, independent of her actual location, according to the schemes:
1) National (significant) number.
2) National (trunk) prefix plus national (significant) number.
3) International prefix*, country code, national (significant) number.
Scheme 3) Storage of numbers in this format is mandatory for all PLMN operators.
If the forwarded-to number is a number in a country other than the HPLMN country, it shall be entered by the served mobile subscriber, independent of her actual location, according to the following scheme:
- International prefix (NOTE), country code, national (significant) number.
NOTE: The MMI for entering of international prefix is defined in 22.030.
The maximum forwarded-to number length is 28 digits.
Principles for interaction with the Barring of Outgoing Calls supplementary services.
Numbers allowed to call according to the Barring of Outgoing call service condition are allowed as forwarded-to numbers for the served mobile subscriber.
Numbers not allowed to call according to the Barring of Outgoing call service condition are not allowed as forwarded-to numbers for the served mobile subscriber.
For Unconditional Call Forwarding the forwarded leg is treated as an outgoing call from the HPLMN country.
For the Conditional Call Forwarding services the forwarded leg is treated as an outgoing call from the LPLMN (HPLMN or VPLMN) country.
Principles for interaction with the Barring of Incoming Calls supplementary services.
When Barring of all incoming calls is active for the served mobile subscriber - no Call forwarding services are allowed for her.
When Barring of all incoming calls when roaming outside the HPLMN country is active and operative - i.e. the served mobile subscriber is roaming outside the HPLMN country, the Conditional Call Forwarding services are not allowed. |
22.083 | Call Waiting (CW) and Call Holding (HOLD); Supplementary Services; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.083/22083-i01.zip | The present document describes the Supplementary Services belonging to the group Call Completion Supplementary Services.

The general aspects, including definitions and recommended provision, of the description of the supplementary services are given in TS 22.004 [2].
Charging services are the supplementary services associated with charging aspects. The group of supplementary services Charging Supplementary Services comprises two services:
- Advice of Charge (Information) - clause 1;
- Advice of Charge (Charging) - clause 2.
Advice of Charge (AoC) supplementary services will use the Charge Advice Information described in 22.024 [3].
In principle, the same type of Mobile Station (MS) can be used for both services of Advice of Charge (AoC), except where the application demands special features - e.g. the payment mechanism in a payphone.
Only one of these services may be subscribed to at any one time. |
22.087 | User-to-User Signalling (UUS); Service description; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.087/22087-i01.zip | The User-to-User Signalling (UUS) supplementary service allows a mobile subscriber to send/receive a limited amount of information to/from another PLMN or ISDN subscriber over the signalling channel in association with a call to the other subscriber. |
22.088 | Call Barring (CB) supplementary services; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.088/22088-i01.zip | The present document describes the supplementary services belonging to the group Call Restriction Supplementary Services.
The general aspects - including definitions and recommended provision - of the description of the supplementary services are given in 3GPP TS 22.004 [2].
The Call Restriction supplementary services allow the possibility for a mobile subscriber to have barring of certain categories of outgoing or incoming calls at the mobile subscribers access.
The group of Call Restriction Services includes two supplementary services:
- barring of outgoing calls;
- barring of incoming calls.
By use of subscription options, the mobile subscriber can at provision time select a set of one or more barring programs to determine the categories of calls to be barred. The following categories are defined:
- all outgoing calls;
- outgoing international calls;
- outgoing international calls except those directed to the home PLMN country;
- all incoming calls;
- incoming calls when roaming outside the home PLMN country.
NOTE 1: Each category (barring program) is handled as a single supplementary service.
NOTE 2: The call barring program "incoming calls when roaming outside the home PLMN country" is only relevant if as a general rule the called mobile subscriber pays the charges for the forwarded part of the call from his home PLMN country to any other country.
The barring services can be offered to a mobile subscriber with a password option allowing the activation and deactivation by the subscriber. One password per mobile subscriber is supported by the network for all barring services. For the definition of the password, the description of its use and its management, see 3GPP TS 22.004 [2]. |
22.090 | Unstructured Supplementary Service Data (USSD); Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.090/22090-i01.zip | The present document defines the stage 1 description of Unstructured Supplementary Service Data (USSD) for use in one or a number of Public Land Mobile Networks (PLMNs). |

22.129 | Service aspects; Handover requirements between UTRAN and GERAN or other radio systems | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.129/22129-i01.zip | The scope of this document includes service requirements for handover maintaining continuity of service to a wireless terminal as it moves between the radio coverage area, or "cells", associated with different base station sites. This functionality is called "handover". Handover can also occur due to change of radio resource providing a service without necessarily any change of the base stations involved. In particular, when the radio resources providing a service change from one of the UTRA radio access modes to the other (UTRA-FDD and UTRA-TDD), this is regarded as handover. Particular emphasis has been placed on the description of requirements for service continuity within UTRAN and between UTRAN and GERAN.
It is a key requirement to allow for dual or multi-mode terminals to handover traffic from UTRAN to GERAN and vice versa. This document describes the service requirements for intra- and inter- system handover.
The following subject areas are within the scope of these service requirements:
- User perceived performance that may be influenced by handover;
- Operational requirements relating to handover;
- Security requirements.
The requirements set forth in this document are service requirements, in that they fulfil the following:
- The requirements are independent of the implementation of the UTRAN;
- The extent to which the requirements are met are in principle verifiable using observables that are not internal to the UTRAN. |
22.135 | Multicall; Service description; Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.135/22135-i01.zip | The present document presents describes Multicall supplementary service.
The general aspects, including definitions and recommended provision, of the description of the 3GPP Supplementary Services are given in 3GPP TS 22.004. |
22.140 | Multimedia Messaging Service (MMS); Stage 1 | TS | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.140/22140-i01.zip | This Technical Specification defines the stage one description of the non real-time Multimedia Messaging Service, MMS. Stage one is the set of requirements which shall be supported for the provision of non real-time multimedia messaging service, seen primarily from the subscriber’s and service providers’ points of view.
This TS includes information applicable to network operators, service providers, terminal and network manufacturers.
This TS contains the core requirements for the Multimedia Messaging Service, which are sufficient to provide a complete service.
This TS defines the requirements for MMS to be understood as a framework to enable non real-time transmissions for different types of media including such functionality as:
- multiple media elements per single message
- individual handling of message elements
- different delivery methods for each message element
- negotiate different terminal and network MM capabilities
- notification and acknowledgement of MM related events (e.g. delivery, deletion, ...)
- handling of undeliverable MM
- personalised MMS configuration
- flexible charging
The above list is not exhaustive.
Thus the MMS enables a unified application which integrates the composition, storage, access, and delivery of different kinds of media, e.g. text, voice, image or video in combination with additional mobile requirements. |

22.950 | Priority service feasibility study | TR | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.950/22950-i01.zip | This Technical Report (TR) presents the results of the Feasibility Study on Priority Service. The intent of this Feasibility Study is to assess the ability of 3GPP specifications to meet high-level requirements identified for Priority Service. This Feasibility Study consisted of a multi-step process, namely:
1. Identify high-level requirements for Priority Service.
2. Determine existing relevant 3GPP specifications for Priority Service.
3. Perform a Gap Analysis to assess the ability of existing 3GPP specifications to meet the high-level Priority Service requirements.
Additional functionalities not documented in this TR are considered outside the scope of this TR. Such additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users. Such additional functionality shall not compromise conformance to the requirements of the Priority Service defined in this specification.
The Priority Service is intended to be utilised for both Voice and Data and therefore both elements are considered within the scope of this document. While Priority Service is meant for both Voice and Data services, the initial set of requirements address Circuit Switched Services (Voice as well as Data). Multimedia and non-circuit switched aspects of Priority Service have not been addressed in this feasibility study and are for further study.
The Priority Service is intended to interwork with external networks to provide an end-to-end service.

22.951 | Service aspects and requirements for network sharing | TR | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.951/22951-i01.zip | In the current dynamic market place, as a result of partnerships, acquisitions, creative agreements among operators and so on, the need for tools that enable various degrees of network sharing is becoming more and more important.
When GSM and then UMTS were specified, the possibility of sharing part or all of the network by two or more separated commercial entities was not considered and as a result the standards lack some functionalities that enable the realisation of such commercial agreements.
GSM was designed under the principle "one operator, one radio access network". The GSM network has some possibilities of infrastructure sharing, but it does not support true radio access network sharing. The initial design of 3GPP system has followed the same principle.
This technical report is aimed to capture the service and user requirements that must be fulfilled by the 3GPP system in order to enable network sharing in a standardised way. Section 5 describes various Network sharing includes various scenarios e.g. spanning from common radio access network connected to multiple core networks toor multiple radio access networks sharing one core network. Section 6 contains a summary of the user classification and network identities. In section 7 the user requirements are described, while section 8 deals with the network operator requirements. Section 9 describes the mobility requirements in a shared network. The rest of the document is covering security (section 10) and charging (section 11). Some conclusions can be found in section 12 and an annex with examples of practical realisation of network sharing is provided. |

22.977 | Feasibility study for speech-enabled services | TR | 18.0.1 | S1 | https://www.3gpp.org/ftp/Specs/archive/22_series/22.977/22977-i01.zip | Speech Enabled Services
The advancement in the Automatic Speech Recognition (ASR) technology, coupled with the rapid growth in the wireless telephony market has created a compelling need for speech-enabled services. Voice-activated dialling has become a de facto standard in many of the mobile phones in the market today. The speech recognition technology has also been applied more recently to voice messaging and personal access services. A Voice Extensible Markup Language (Voice XML) has been designed to bring the full power of web development and content delivery to voice response applications [11]. Voice portals that provide voice access to conventional graphically oriented services over the Internet are now becoming popular. Forecasts show that speech-driven services will play an important role on the 3G market. Users of mobile terminals want the ability to access information while on the move and the small portable mobile devices that will be used to access this information need improved user interfaces using speech input.
Multimodal and Multi-device Services
Speech-enabled services may utilize speech alone for input and output interaction, or may also utilise multiple input and output modalities leading to the multimodal services.
Online access to information is fast becoming a must-have. Along with this trend, come new usage models for information access, particularly in mobile environments. Information appliances in cars such as navigation systems are standard in high-end cars already and this will penetrate lower-end vehicles soon. Data access using mobile phones, though limited and currently estimated to take three years to be widespread, has significant momentum that makes it certain to become widespread. In this new computing paradigm a person will expect to have access to information and interactions in a seamless manner in many environments, be it in the office, at home, in the car, often on several different devices. These new access methods have compelling advantages, such as mobile accessibility, low cost, ease of use, and mass market penetration. They also have their limitations - in particular, it is hard to enter and access data using small devices, speech recognition can introduce mistakes that can sometimes be repeating and therefore blocking the transaction; one interaction mode does not suit all circumstances, and so on.
For example, a recent study of task-performance using wireless phones, such as reading world headlines and checking local weather concluded that currently, these services are often poorly designed, have insufficient task analysis, and abuse existing non-mobile design guidelines. The full report from the field study can be downloaded at [6]. The basic conclusion of this study is that wireless access usability fails miserably; accomplishing even the simplest of tasks takes much too long to provide any user satisfaction. It is thus essential for the widespread acceptance of this computing paradigm to provide an efficient and usable interface on the different device platforms that people are expected to use to access and interact with information.
We can expect and already observe a trend towards a new frontier of interactive services: multimodal and multi-device services.
These services exploit the fact that different interaction modes are good at different things - for example, talking is easier than typing, but reading is faster than listening. Multi-modal interfaces combine the use of multiple interaction modes, such as voice, keypad and display to improve the user interface to services.
Different standard bodies are addressing aspects of this space, driven by several industry proposals: W3C (e.g. MMI activity)[11], OMA/WAP Forum, ETSI [1], IETF[14],…). In particular, the W3C MMI [13] aims at defining a programming model for multimodal and multi-device applications.
Additional details and motivations are discussed in [2, 7, 8].
Overview
A brief overview of the speech-enabled services is presented in Chapter 4. The different ways of enabling speech recognition for the speech enabled services are described in chapter 5. Section 6 discusses multimodal services and options to enable multimodal and multi-device services. The scope of the report, references, definitions and abbreviations are detailed in the first few chapters. |
