Service level interworking for messaging services; Stage 2
This document contains the results of the study into the architectural requirements and comes up with the solution of the service level interworking for the Short Message service as defined in the TS 23.040 [6] and Instant Messaging service as defined in OMA-TS-SIMPLE_IM-V1_20070816-C [8]. Considerations include overall requirements, architectural requirements, evaluation of potential architectural solutions and alternative architectures.
The objective is to identify an architectural solution that allows completely service level interworking between SMS and SIMPLE IM without degrading existing services, under the service requirements defined in the TS 22.340 [2] and TS 22.105 [3]. In addition, how to charge for the interworked services shall be considered in this study as well.
