Abstract:
1. A method for wireless communications, comprising: creating a radio session associated with an access terminal at a target access network controller, the radio session corresponding with a source radio session at a source access network controller, wherein the source radio session is locked, 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, establishing a communication route between a data network and the access terminal via the target access network controller; receiving, by the target access network controller, a frozen state associated with the source radio session from the source access network controller, wherein the frozen state includes a snapshot of any data being communicated through the source radio session when freezing occurred; unfreezing the received frozen state; and unlocking the radio session.
