SERVICE-BASED NETWORK SELECTION
Abstract:
Systems and techniques enable an improved network selection procedure. Providers maintain preferred networks lists provisioned to UEs. The preferred networks lists include WLAN RATs, and for each entry coverage area and type of supported services. UEs include multiple credentials for connectivity via providers and potentially multiple transceivers supporting multiple active services. A UE triggers a network selection procedure whenever a new service is initiated. A credential is selected. The UE builds a list of network/RAT combinations from preferred networks lists and filters this list, removing entries that do not support the new service. The UE takes the context of the UE into consideration, further filtering the list. The remaining entries are scanned and a network/RAT combination selected. The UE determines whether registering with the selected network/RAT combination causes an interruption to an ongoing service. If not, the UE registers on the selection. If so, the UE engages in interruption resolution.
