Abstract
Described herein are apparatus, systems and methods for improved mobility between wireless networks. A method may comprise, at a user equipment (“UE”) in communication with a cellular network activating a detach timer for the cellular network, detecting a short-range network, communicating with the short-range network, storing registration and bearer context data related to the cellular network, interrupting communication with the cellular network, and prior to the expiration of the detach timer, reconnecting to the cellular network via a service request without using an attach procedure.
Claims18
A method, comprising:
- at a user equipment (“UE”) in communication with a cellular network:
- activating a detach timer for the cellular network, wherein the detach timer indicates a time until the UE detaches from the cellular network;
- communicating with a short-range network;
- storing registration and bearer context data related to the cellular network;
- while in communication with the short-range network, discontinuing communication with the cellular network;
- prior to discontinuing communication with the cellular network and in response to communicating with the short-range network, initiating, by the UE, a Radio Resource Control (“RRC”) protocol connection with the cellular network, wherein the RRC protocol connection causes the detach timer to reset to an initial value;
- and
- prior to the expiration of the detach timer, reconnecting to the cellular network via a service request using the stored registration and bearer context data without using an attach procedure.
A user equipment (“UE”) device, comprising:
- a memory arrangement;
- a cellular transceiver configured to communicate with a cellular network;
- a non-cellular transceiver configured to communicate with a short-range network;
- a detach timer;
- and
- a processor that activates the detach timer for the cellular network and stores registration and bearer context data related to the cellular network when the UE discontinues communication with the cellular network and connects to the short-range network,
- wherein, prior to discontinuing communication with the cellular network and in response to communicating with the short-range network, the processor initiates a Radio Resource Control (“RRC”) protocol connection with the cellular network, wherein the RRC protocol connection causes the detach timer to reset to an initial value;
- wherein the detach timer indicates a time until the UE detaches from the cellular network;
- and
- wherein prior to the expiration of the detach timer, the cellular transceiver reconnects to the cellular network via a service request using the stored registration and bearer context data without using an attach procedure.
An integrated circuit in communication with a non-volatile computer-readable medium that stores instructions that, when executed by the integrated circuit, cause the integrated circuit to perform operations including:
- activating a detach timer for a cellular network, wherein the detach timer indicates a time until a UE detaches from a cellular network;
- communicating with a short-range network;
- storing registration and bearer context data related to the cellular network;
- while in communication with the short-range network, discontinuing communication with the cellular network;
- prior to discontinuing communication with the cellular network and in response to communicating with the short-range network, initiating, by the UE, a Radio Resource Control (“RRC”) protocol connection with the cellular network, wherein the RRC protocol connection causes the detach timer to reset to an initial value;
- and
- prior to the expiration of the detach timer, reconnecting to the cellular network via a service request using the stored registration and bearer context data without using an attach procedure.
