Abstract
Embodiments of a system and method for wireless communication are provided. In certain embodiments, systems and methods for providing seamless reconfiguration of a network which incorporate known features of the network. In some embodiments, the mobile station implements a hand over from one physical base station to the same physical base station, so as to allow that base station to reconfigure and update configuration parameters.
Claims23
A method for wireless communication performed by a mobile station, the method comprising:
- receiving a message from a base station with which the mobile station has a current connection, wherein the message includes information regarding a configuration change of the base station;
- halting the current connection with the base station;
- updating parameters corresponding to the configuration change based on the message;
- and
- resuming a connection with the base station using the updated parameters.
A method for wireless communication performed by a base station, the method comprising:
- determining that the base station is to perform reconfiguration, wherein the reconfiguration includes changing a physical layer parameter, such that the base station is to operate according to an updated physical layer parameter after the reconfiguration;
- transmitting a handover request to a mobile station communicating with the base station, the handover request requesting that the mobile station handover to a base station having the updated physical layer parameter, such that the mobile station performs a handover from the base station having a non-updated physical layer parameter prior to reconfiguration to the base station after reconfiguration having the updated physical layer parameter.
A method for wireless communication performed by a base station, the method comprising:
- determining that the base station is to perform reconfiguration, wherein the reconfiguration includes changing a physical layer parameter, such that the base station is to operate according to an updated physical layer parameter after the reconfiguration;
- transmitting a reconfiguration notification to a mobile station communicating with the base station, the reconfiguration notification providing the mobile station with information regarding the updated physical layer parameter;
- disconnecting with the mobile station;
- performing reconfiguration;
- and
- reconnection with the mobile station after reconfiguration using the updated physical layer parameter.
A wireless device comprising:
- an RF transceiver for transmitting and receiving signals from a base station;
- processing circuitry communicatively coupled to the RF transceiver and configured to:
- receive a message from a base station with which the mobile station has a current connection, wherein the message includes information regarding a configuration change of the base station;
- halt the current connection with the base station;
- update parameters corresponding to the configuration change based on the message;
- and
- resume a connection with the base station using the updated parameters.
A base station for providing wireless communication with a plurality of mobile stations, the base station comprising:
- an RF transceiver for transmitting to and receiving signals from a plurality of mobile stations;
- and
- processing circuitry communicatively coupled to the base station, the processing circuitry configured to:
- determine that the base station is to perform reconfiguration, wherein the reconfiguration includes changing a physical layer parameter, such that the base station is to operate according to an updated physical layer parameter after the reconfiguration;
- transmit a reconfiguration notification to a mobile station communicating with the base station, the reconfiguration notification providing the mobile station with information regarding the updated physical layer parameter;
- disconnect with the mobile station;
- perform reconfiguration;
- and
- reconnect with the mobile station after reconfiguration using the updated physical layer parameter.
