Abstract
A method includes, in a mobile communication terminal, detecting degradation in communication quality between the terminal and a serving base station during establishment of a call via the serving base station. During the establishment of the call via the serving base station, the terminal searches for an alternative base station that is suitable for establishing the call. Upon finding the alternative base station, a switch is made to establish the call via the alternative base station.
Claims18
A method, comprising:
- in a mobile communication terminal, detecting a degradation in communication quality between the mobile communication terminal and a serving base station during a call-setup procedure in which the terminal attempts to establish a call via the serving base station, wherein the call-setup procedure begins with the mobile communication terminal sending a “Radio Resource Control (RRC) connection request” message to the serving base station and ends with the mobile communication terminal sending an “RRC connection setup complete” message to the serving base station, and wherein the call-setup procedure specifies that the mobile communication terminal is to dedicate all time resources for establishing the call with the serving base station;
- responsive to detecting the degradation in the communication quality, searching by the mobile communication terminal, during the call-setup procedure with the serving base station, for an alternative base station that is suitable for establishing the call, even though the call-setup procedure specifies that all time resources of the mobile communication terminal are to be dedicated for establishing the call with the serving base station;
- and
- upon finding the alternative base station, switching to establish the call via the alternative base station.

An apparatus, comprising:
- a transceiver, which is configured to communicate with base stations;
- and
- processing circuitry, which is configured to:
- detect a degradation in communication quality with a serving base station during a call-setup procedure in which the transceiver attempts to establish a call via the serving base station, wherein the call-setup procedure begins with the transceiver sending a “Radio Resource Control (RRC) connection request” message to the serving base station and ends with the transceiver sending an “RRC connection setup complete” message to the serving base station, and wherein the call-setup procedure specifies that the transceiver is to dedicate all time resources for establishing the call with the serving base station,
- search, during the call-setup procedure via the serving base station, for an alternative base station that is suitable for establishing the call, even though the call-setup procedure specifies that all time resources of the transceiver are to be dedicated for establishing the call with the serving base station, and,
- upon finding the alternative base station, switch to establish the call via the alternative base station.
