Abstract

The invention provides for a method for use in a mobile radio communications network connection procedure and including the step of rejecting at a mobile radio communications device a handover request from a network responsive to determination of support of the security algorithm associated with the handover, and for a mobile radio communications device arranged to determine support of security algorithms as proposed by the network, preferably at AS level, within a handover command, and to provide notification to the network of rejection of the connection due to non-support of the algorithm.

Claims

1. A method for use in a mobile radio communications network connection procedure, the method including the step of rejecting at a mobile radio communications device a handover request from a network responsive to determination of the support of the security algorithm associated with the handover.

2. A method as claimed in claim 1, further including the step of determining the support of the security algorithm as proposed by the network.

3. A method as claimed in claim 2, wherein the security algorithm is proposed at the Access Stratums level within the network.

4. A method as claimed in claim 1, wherein the algorithm is proposed by the network by way of a handover command.

5. A method as claimed in claim 1, further including the step of providing notification from the mobile radio communications device to the network of connection failure due to non-support of the security algorithm.

6. A method as claimed in claim 1, wherein only one of the network or the mobile radio communications device is initially arranged to support or operate with an upgraded algorithm.

7. A method as claimed in claim 1, further including the step of initiating within the network, a handover procedure with a second algorithm different from the unsupported algorithm.

8. A method as claimed in claim 1, further including the step of re-initiating a handover procedure within the network.

9. A mobile radio communications device arranged to determine support of security algorithms therein and further arranged to reject a network connection request responsive to said determination of the support of the security algorithm.

10. A device as claimed in claim 9, and arranged to receive details of a security algorithm as proposed by the network.

11. A device as claimed in claim 10, and arranged to receive said details within a handover command.

12. A device as claimed in claim 9, and further arranged so as to provide notification to the network of the rejection of the connection.

13. A mobile radio communications network device forming part of a network for achieving connection to a mobile radio communications device and arranged to receive a connection-rejection notification from the mobile radio communications device due to an unsupported algorithm and to re-initiate a connection procedure with a second security algorithm different from the un-supported algorithm.
