SIMULTANEOUS HAND OVER IN DIFFERENT DOMAINS

摘要

The teachings relates to method (40) in a target network (node16) of a target core network in a first domain during handover, in the first and in a second domain, of a communication device (20) from a source radio access network to a target radio access network. The source radio access network comprises a source access node (11) and the target radio access network comprises a target access (node12). The method (40) comprises determining (41) whether the communication device (20) has access admission to the target core network; when a hand over fails generating (42) a hand over failure message comprising an information element “Independent domain HandOver”, where in the information element is set to a predefined value indicating whether the hand over failed due to lack of access rights or for other reasons than lack of access rights. The teachings also relates to devices and further to methods in source nodes.

1. A method in a target network node of a target core network in a first domain during handover, in the first and in a second domain, of a communication device from a source radio access network to a target radio access network, the source radio access network comprising a source access node and the target radio access network comprising a target access node, the method comprising:
determining whether the communication device has access admission to the target core network, when a handover fails generating a handover failure message comprising an information element “Independent domain HandOver,” wherein the information element is set to a predefined value indicating whether the handover failed due to lack of access rights or for other reasons than lack of access rights.
