Method and apparatus to enable a UE to return to a wireless network after failure to obtain service
Abstract:
Techniques for enabling a user equipment (UE) to return to a wireless network after failure to obtain a particular service (e.g., voice service) are described. The UE may determine that the wireless network does not support the particular service at a first location (e.g., the current UE location). In response, the UE may disable the wireless network and may refrain from attempting to obtain the particular service (or possibly any service) from the wireless network. The UE may thereafter re-enable the wireless network based on a trigger, which may result from a timer, an event, or broadcast information from another wireless network. After re-enabling the wireless network, the UE may perform cell search and system selection and may detect and select the wireless network. The UE may determine that the wireless network supports the particular service at a second location and may obtain the particular service from the wireless network.
