20100113010 | REPRIORITIZATION OF WIRELESS NETWORKS FOR RESELECTION TO SUPPORT VOICE CALL - Techniques for originating a voice call by a UE after performing reselection with reprioritization are described. The UE may operate in an idle mode and may camp on a first wireless network of a first radio access technology (RAT), which may not support voice service. The first wireless network may have the highest priority among all wireless networks detected by the UE. The UE may receive an indication to originate a voice call. The UE may then perform reselection from the first wireless network to a second wireless network of a second RAT by modifying the priorities of the frequencies of the first wireless network and/or the second wireless network. The UE may then originate the voice call with the second wireless network, instead of the first wireless network, in order to avoid having to perform circuit-switched (CS) fallback from the first wireless network to the second wireless network. | 05-06-2010 |
20110044248 | RELIABLE INTER-RADIO ACCESS TECHNOLOGY CORE NETWORK TUNNEL - A method of a mobile switching center includes determining if a message belongs to a first set of messages or a second set of messages, filtering the message when the message belongs to the first set of messages, and sending the message when the message belongs to the second set of messages.

Each PLMN ID may be associated with a CDMA2000 network sharing the LTE RAN. A CDMA2000 network may be selected for circuit-switched fallback of a user equipment operating in the LTE RAN. The user equipment may be configured to perform a circuit-switched fallback procedure on the selected CDMA2000 network. The CDMA2000 network may be selected by a mobility management entity responsive to a PLMN selection procedure. The PLMN selection procedure may be performed when the UE reports multiple-operator capability. | 02-12-2015 |
