Abstract
A mobile station for receiving delay-sensitive data from a wireless communications network is provided with a data buffer and cell reselection controller. The data buffer receives data from the network and stores the data for communication to a delay-sensitive data application. The cell reselection controller selectively inhibits cell reselection in order to meet requirements of the delay-sensitive data application. By intelligently controlling cell reselection, delay sensitive data may be received in a more reliable fashion, thereby increasing performance of the data application.
Claims19
A computer-readable medium of a mobile station comprising computer-executable instructions that, when executed by a processor of the mobile station, cause the processor to perform steps of a method, comprising:
- receiving data at the mobile station from a serving cell of a wireless communications network, the data relating to a data application associated with the mobile station;
- measuring a serving cell signal strength of the serving cell;
- measuring a second signal strength of another cell;
- comparing the serving cell signal strength to the second signal strength;
- initiating cell reselection if:
- the data application does not comprise the delay-sensitive application;
- a break in the data received for the data application comprises a natural break;
- and
- the second signal strength is sufficient;
- and
- inhibiting the cell reselection if:
- the data application comprises the delay-sensitive application;
- and
- the cell reselection will result in loss of a data packet for the delay-sensitive data application.
