Drafting Session on eProSe-Ext topics Qualcomm Inc. (rapporteur)

Service continuity What is the issue? Whether ProSe/EPS would provide IP address preservation and what is the solution to provide service continuity when the UE moves from “network coverage” (e.g. LTE-Uu) to ProSe UE-NW Relay coverage and vice versa What are the proposed principles? A. IP address preservation provided at ProSe/EPS layer As proposed in S (Qualcomm, Huawei, Ericsson, USDOC)  HandledS B. IP address preservation is NOT provided at ProSe/EPS layer, service continuity is provided by “application/service layer” As proposed in S (Intel, ALU, BlackBerry)  HandledS What are the proposed alternative solutions based on these principles? IP address preservation provided at ProSe/EPS layer Alt. A1): S (Ericsson)  HandledS Alt. A2): S (Huawei)S Alt. A3): S (Nokia Networks)S IP address preservation is NOT provided at ProSe/EPS layer, service continuity is provided by “application/service layer” Alt. B1): S (LG Electronics)S Alt. B2): S (Intel, ALU, BlackBerry)  HandledS

Group Priority/QoS What is the issue? Whether Group priority is needed and how it provided to the UE and network (e.g. RAN) What are the proposed principles? A. Group Priority is needed and it has to be provided to the UE and network As proposed in S (Ericsson), S (Qualcomm), S (Huawei)S S S B. Static Group Priority is not needed, only “per packet” priority provided in the UE from application As proposed in S (ALU, Intel)S What are the proposed alternative solutions based on these principles? If A is preferred, how Group Priority is provided to UE and RAN Alt. A1): S (Ericsson)S Alt. A2): S (Huawei)S Alt. A3): S (Qualcomm)  proposes alternatives but leaves the exact alternative FFSS If B is preferred S (ALU, Intel) is the only optionS

Model B discovery What is the issue? Whether the ProSe Response Code will be sent via the network or directly What is the proposed principle? A. Response code provided over the network As proposed in S (Huawei)S B. Response code provided directly As proposed in S (Qualcomm Inc.)S What are the proposed alternative solutions based on the principle? If A is preferred, then move forwards with S (Huawei)S If B is preferred, then move forward with S (Qualcomm Inc.)S
