A NETWORK NODE A MOBILITY MANAGEMENT NODE AND METHODS THEREIN FOR HANDLING GTP TUNNEL FAILURES IN A RADIO COMMUNICATIONS NETWORK

摘要

A method performed by a network node (110) for handling a GTP tunnel failure in a radio communications network (100) is provided. The network node (110) receives a release message from a mobility management node (150) for a wireless device (121) associated with the network node (110). The release message comprises information identifying at least one E UTRAN Radio Access Bearer E RAB and information that the release message was caused by a GPRS Tunneling Protocol GTP error indication. The network node (110) also allocates one or more tunnel end point identifiers TEIDs for the at least one E RAB identified in the received release message. Then the network node (110) transmits a modification message to the mobility management node (150) to modify the at least one E RAB identified in the received release message said modification message comprising the allocated one or more TEIDs for the at least one E RAB. A network node for handling a GTP tunnel failure in a radio communications network (100) is also provided. A mobility management node (150) and a method therein for handling a GTP tunnel failure in a radio communications network (100) is also provided.
