Method and apparatus for maintaining location continuity for a UE following handover |
摘要 |
Techniques for maintaining location continuity for a user equipment (UE) following handover are described. The UE communicates with a first radio access network (RAN) and is served by a source serving node and a source location server prior to handover. The UE communicates with a second RAN and is served by a target serving node and a target location server after the handover. In an aspect, location continuity may be maintained for the UE by transferring an identity of the target serving node to a location server during handover of the UE. In one design, the target serving node sends its identity to the target location server, which updates a Location and Routing Function (LRF) serving the UE. In another design, for handover from packet-switched domain to circuit-switched domain, the source serving node sends the target serving node identity to the source location server, which updates the LRF. |

1. A method of receiving location services, the method comprising:
communicating, by a user equipment (UE), with a first radio access network (RAN) prior to a handover; receiving, by the UE via the first RAN prior to the handover, information for the location services from a source location server; communicating, by the UE with a second RAN after the handover; and receiving, by the UE via the second RAN after the handover, information for the location services from a target location server, the target location server being different from the source location server. |
