Abstract

Techniques for performing system searches to find a suitable cell to receive full service while camped on a cell with limited service are described. Initially, a user equipment (UE) may camp on a first cell and receive limited service. The UE may perform a system search in background to find a suitable cell to receive full service. By performing the system search in background, the UE can receive paging messages and perform cell reselection and/or other tasks while the system search is pending and may also be able to obtain limited service with little or no delay when requested by a user. The UE may suspend the system search prior to each paging occasion, receive paging messages applicable for the UE, and then resume the system search. The UE may receive a request for limited service (e.g., emergency call), suspend or abort the system search, and obtain the requested limited service.
