  • Patent number: 9408104
    Abstract: A method and system to help manage wireless communication with a UE in a manner that takes into account a predicted impact of data bundling, such as TTI bundling, with respect to communication of data during a session. When a radio access network (RAN) is going to serve a UE with data communication for a VoLTE call or other session that would trigger such bundling, the RAN will predict the extent of other data that will be communicated during the session, and the RAN will predict the impact, such as increased air interface load, that would result from data bundling of at least that other data communication. If the RAN thereby predicts that the impact of data bundling with respect to at least that other data communication will exceed a predefined threshold level, then the RAN will responsively take action to limit its air interface communication with the UE.

  • Patent number: 9401834
    Abstract: A method and system for responding to a call-teardown request generated, for instance, as a result of a user equipment device (UE) losing coverage of a first serving radio access network (RAN) while the UE is engaged in a call with another party. A signaling intermediary receives the call-teardown message en route from a first call server to a second call server and responsively determines whether the UE is now served by a second RAN. Responsive to determining that the UE is served by the second RAN, the intermediary arranges for establishment of a new call connection with the UE via the second RAN and for linking of the new call connection with an existing leg of the call with the other party, and the intermediary discards the call-teardown message rather than forwarding it along to the second call server.

  • Patent number: 9386563
    Abstract: A method and system is disclosed for coordinating codec consistency based on cross-carrier assignments. When a new voice call (or other communication session) is set up between access terminals in a wireless communication system, a network device, such a base station, can determine a respective maximum coding rate supported on carrier frequencies of both an originating access terminal and a terminating access terminal. The network device can then select a coding rate that best accommodates the respective maximum coding rates. Each access terminal may then be instructed to use the selected coding rate for the new call (or communication session). Either or both access terminals may also execute a frequency handoff to a carrier frequency that supports the selected coding rate, if necessary.
