Study on location enhancements for mission critical services
The present document identifies the impact of location requirements from stage 1 that have yet to be realized within the stage 2 MC services architecture, and to propose solutions and enhancements where needed to fulfil these requirements.
Based on any gaps found between stage 1 service level requirements and existing MC location architecture, the present document consists of a technical report that includes: identification of key issues and gaps with the existing location architecture as specified in 3GPP TS 23.379 [6], 3GPP TS 23.280 [7], 3GPP TS 23.281 [8], and 3GPP TS 23.282 [9]; associated solutions for enhancements to existing MC location architecture; and corresponding evaluations and conclusions.
The location enhancements considered in the present document are limited to MC services over EPS.
