Abstract:
1. A method for wireless communications, comprising: locking a source radio session associated with an access terminal at a source access network controller, the source access network controller in communication with a data network, wherein locking permits updating existing configurations and attributes associated with the source radio session but prevents initiation of new configurations and attributes for the source radio session by at least one of the access terminal or the source access network controller; freezing a state associated with the source radio session, wherein the state includes a snapshot of any data being communicated through the source radio session when freezing occurs; instructing a target access network controller to create a target radio session corresponding with the source radio session; instructing the target access network controller to establish a communication route between the data network and the access terminal via the target access network controller; and transferring the frozen state associated with the source radio session to the target access network controller prior to terminating the source radio session associated with the source access network controller.
