Improved handling of high-speed users within a heterogeneous mobile network by means of RLF timer adjustment

摘要

The present invention relates to a method and apparatus for managing mobility within a macro cell (C1) having a large radio coverage area (210).
A radio communication channel is set up with a particular mobile device (UE1), and the particular mobile device is characterized as being a high-speed mobile device. The particular mobile device is then configured with an augmented RLF timer value to be used by high-speed mobile devices for call resumption with the serving macro cell.
A measurement event for the particular mobile device is then detected, whereby a neighboring cell (C2) was measured as being offset better than the macro cell. The neighboring cell is characterized as having a substantially shorter radio coverage area (220) enclosed by the large radio coverage area.
Upon detection of the measurement event, the particular mobile device keeps on being served by the macro cell. The augmented RLF timer value is relied upon for the mobile device to resume call directly with the serving macro cell in case the mobile device undergoes strong radio interference from the neighboring cell and detects radio problems.
