Abstract
A packet-switching connection is set up from a mobile station through a first transceiver unit, whereby the mobile station is assigned to a first cell and a first residence zone. As the mobile station moves to a second cell and a second residence zone, the connection is assigned a residence zone change identification. A transfer procedure for the packet-oriented connection from the first cell to the second cell is carried out. After the transfer procedure a data exchange by the packet-switched connection is reestablished. After reestablishing the data exchange a procedure for residence zone exchange is carried out.
Claims20
A method for carrying out a handover in a radio communication system, comprising:
- establishing a packet switched connection from a mobile station to a first cell via a first transceiver unit, the mobile station being assigned to a first routing area in the first cell;
- assigning a routing area update identifier to the connection if the mobile station moves into a second cell which is served by a second transceiver unit, and into a second routing area;
- performing a handover of the packet switched connection from the first cell to the second cell;
- during at least a portion of the handover, pausing an exchange of data via the packet switched connection;
- after the handover, resuming the exchange of data via the packet switched connection;
- and
- updating the routing area from the first routing area to the second routing area, after the exchange of data is resumed.
A radio communication system comprising:
- a first routing area;
- a first cell to establish a packet switched connection with a mobile station, the first cell being located in the first routing area;
- a second routing area;
- a second cell located in the second routing area;
- a first identifier device, associated with the first routing area, to assign a temporary identifier to the connection if the mobile station moves from the first cell to the second cell;
- a second identifier device, associated with the second routing area, to assign a second identifier to the connection after a handover of the connection from the first cell to the second cell, after data exchange is paused during the handover, and after data exchange is resumed when the handover is completed.
A method for carrying out a handover in a radio communication system, comprising:
- establishing a packet switched connection from a mobile station to a first cell, the first cell being within a first routing area;
- assigning a routing area update identifier to the connection if the mobile station moves into a second cell in a second routing area;
- performing a handover of the packet switched connection from the first cell to the second cell;
- during at least a portion of the handover, pausing an exchange of data via the packet switched connection;
- after the handover, resuming the exchange of data via the packet switched connection;
- and
- updating the routing area from the first routing area to the second routing area, after the exchange of data is resumed.
