System and method for supporting switching between a packet-switched network and a circuit-switched network

摘要

A device and method for controlling communications between a User Equipment (UE) (20) and a base station (BS) (90) in a radio access network (RAN) (16) is provided. The UE (20) indicates to the BS (90) in the RAN (16) that a transceiver at the UE (20) will temporarily suspend communications with the RAN (16). The BS (90) acknowledges the indication from the UE (20) and temporarily suspends communications with the UE (20). Responsive to the acknowledgement from the BS (90), the UE (20) temporarily suspends communications between the transceiver and the RAN (16). The UE (20) then resumes communications between the transceiver and the BS (90) in the RAN (16).

1. A method for controlling communications between a User Equipment (UE) and a base station in a radio access network (RAN), the method performed by the UE and comprising:
indicating to the base station that a transceiver at the UE will temporarily suspend communications with the RAN by sending a Media Access Control (MAC) element to the base station over an uplink shared channel (UL-SCH); temporarily suspending communications between the transceiver and the RAN responsive to receiving a response from the base station acknowledging the indication; and resuming communications between the transceiver and the base station in the RAN, wherein the UE sends a Random Access Request or a Scheduling Request to the base station when resuming communications between the transceiver and the base station.
