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.
Claims29
A mobile station comprising:
- a data buffer configured to store data packets received from a wireless communications network;
- a data application in communication with the data buffer, the data application being configured to receive data from the data buffer;
- and
- a cell reselection controller in communication with the data buffer, the cell reselection controller being configured to:
- determine if the data application comprises a delay-sensitive data application;
- receive a serving cell signal strength of a serving cell of the wireless communications network;
- receive a second signal strength of another cell of the wireless communications network;
- initiate a cell reselection;
- and
- inhibit the cell reselection, wherein:
- the cell reselection controller is configured to initiate the cell reselection if:
- the data application does not comprise the delay-sensitive application;
- a break in data received for the data application comprises a natural break;
- and
- the second signal strength is sufficient;
- and
- the cell reselection control is configured to inhibit 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.

A method, comprising:
- receiving data at a 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;
- determining, at a cell reselection controller, whether cell reselection should be initiated or should be inhibited;
- and
- if the cell reselection controller determines to inhibit the cell reselection, executing an action, wherein the cell reselection controller is configured to:
- determine if the data application comprises a delay-sensitive application;
- initiate the cell reselection if:
- the data application does not comprise the delay-sensitive application;
- a break in data received for the data application comprises a natural break;
- and
- the second signal strength is sufficient;
- and
- the cell reselection control is configured to inhibit 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.
15 more elements
A telecommunications system, comprising:
- a wireless network;
- and
- at least one mobile station in communication with the wireless network, the mobile station comprising:
- a data application for receiving data from a serving cell of the wireless network;

- a break in data received for the data application comprises a natural break;
- and
- the second signal strength is not sufficient;
- and
- the cell reselection control is configured to inhibit 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.
