Abstract
A network can send cell reselection criteria to a mobile terminal. The mobile terminal measures or otherwise obtains radio condition measurements (such as received power, interference, mobile transmit power and the like) and/or geographical location measurements. The mobile can maintain a history of the cell selection criteria and/or measurements. The radio condition measurements are compared against historical data and/or cell reselection criteria and, based on the comparison; the mobile terminal can initiate cell reselection.
Claims10
A method for mobile based cell reselection, the method comprising, at a mobile terminal:
- receiving radio resource management (RRM) parameter adjustment configuration data from a network device;
- storing cell reselection criteria information from the RRM parameter adjustment configuration data;
- obtaining a radio condition measurement for a neighboring cell;
- storing cell measurement information from the radio condition measurement;
- selectively adjusting an RRM parameter based, at least in part, on the RRM parameter adjustment configuration data and the radio condition measurement;
- and
- selectively initiating a cell reselection based, at least in part, on the adjusted RRM parameter, the stored cell measurement information, and the stored reselection criteria information.
An article comprising:
- a non-transitory computer readable medium having stored therein instructions to be executed by a processor in a mobile terminal to:
- access radio resource management (RRM) parameter adjustment configuration data received from a network device;
- store cell reselection criteria information from the RRM parameter adjustment configuration data;
- obtain a radio condition measurement for a neighboring cell;
- store cell measurement information from the radio condition measurement;
- selectively adjust an RRM parameter based, at least in part, on the RRM parameter adjustment configuration data and the radio condition measurement;
- and
- selectively initiate a cell reselection based, at least in part, on the adjusted RRM parameter, the stored cell measurement information, and the stored reselection criteria information.
A mobile terminal comprising:
- a communication module;
- and
- a processor to:
- receive radio resource management (RRM) parameter adjustment configuration data from a network device via the communication module;
- store cell reselection criteria information from the RRM parameter adjustment configuration data;
- obtain at least one radio condition measurement for a neighboring cell;
- store cell measurement information from the radio condition measurement;
- selectively adjust an RRM parameter based, at least in part, on the RRM parameter adjustment configuration data and the radio condition measurement;
- and
- selectively initiate a cell reselection based, at least in part, on the adjusted RRM parameter, the stored cell measurement information, and the stored reselection criteria information.
An apparatus for mobile based cell reselection, the apparatus comprising:
- means for receiving radio resource management (RRM) parameter adjustment configuration data from a network device;
- means for storing cell reselection information from the RRM parameter adjustment configuration data;
- means for obtaining a radio condition measurement for a neighboring cell;
- means for storing cell measurement information from the radio condition measurement;
- means for selectively adjusting an RRM parameter based, at least in part, on the RRM parameter adjustment configuration data and the radio condition measurement;
- and
- means for selectively initiating a cell reselection based, at least in part, on the adjusted RRM parameter, the stored cell measurement information, and the stored reselection criteria information.
