Abstract
A cellular radio communication system has a number of cells covered by base stations communicating with mobile communication devices. The mobile communication device performs an idle handoff method. In the idle handoff method, the communication mobile device receives paging messages from a first base station, and initiates idle handoff from the first base station to a second base station if it is established that no other, critical idle-mode process with the first base station is being performed.
Claims18
In a mobile communication device comprised in a cellular radio communication system that further comprises a plurality of base stations an idle-mode handoff method, said method comprising:
- operating a physical layer software process;
- operating a data link layer software process;
- operating a call control software process;
- receiving paging messages from a first base station;
- and
- determining, within the mobile communication device, whether a critical idle-mode process is running in the call control layer software process;
- initiating an idle-mode handoff process from said first base station to a second base station if the determination is affirmative.
A cellular radio communication system comprising:
- a plurality of cells having base stations covering said cells;
- and
- a mobile communication device comprising means for receiving paging messages from a first base station, and means for operating a physical layer software process;
- means for operating a data link layer software process;
- means for operating a call control layer software process;
- means for determining, within the mobile communication device, whether a critical idle-mode process is running in the call control layer software process;
- and
- means for initiating an idle-mode handoff process from said first base station to a second base station if the determination is affirmative.
A mobile communication device for use in a cellular radio communication system having a plurality of cells with base stations covering said cells, said mobile communication device comprising:
- means for receiving paging messages from a first base station;
- means for operating a physical layer software process;
- means for operating a data link layer software process;
- means for operating a call control layer software process;
- and
- means for initiating an idle-mode handoff process from said first base station to a second base station responsive to an affirmative determination by the means for determining.
