This TR presents the results of the Study on LCS support for non-3GPP accesses.

One main concept of EPC is to support a variety of different access systems (existing and future) ensuring mobility and service continuity between these access systems. In that perspective, the LCS support for non 3GPP accesses should be also taken into account. However, historically, TS 22.071 has been applicable only to 3GPP accesses and any new requirements for non 3GPP accesses have not been discussed yet.

Therefore we need to consider how to support LCS in EPC for non 3GPP accesses, e.g. 3GPP2 and WiMAX. Supporting LCS in EPC for non 3GPP access does not necessarily mean that all positioning methods available in various kinds of non 3GPP accesses should be supported in EPC or inventing new positioning methods for other accesses. However, how to realize the presentation of location information in EPC when users are connected in non 3GPP accesses should be at least taken into account. In addition, the service scenarios should be discussed whether new service requirements are needed for the users camping on non 3GPP accesses through EPC.

This work will examine whether requirements in TS 22.071 would be applicable for non 3GPP accesses and specify new service requirements for the users connected to non 3GPP accesses through EPC.

Consideration will be given, but not limited, to the following:
  • High level requirements of LCS support for non 3GPP accesses;
  • Location information provided to the LCS client for non 3GPP accesses;
  • QoS requirements of LCS support for non 3GPP accesses.
  • Priority between different LCS services for non 3GPP accesses.
  • Privacy requirements of LCS support for non 3GPP accesses.
  • Periodic location report of LCS services for non 3GPP accesses.
  • Impact on the LCS client and the LCS server to support LCS services for non 3GPP accesses.
