Abstract
The present invention relates to a method for closing all network connections to a detached user equipment. The local mobility anchor (LMA) receives and reads a control message saying that the user equipment is detached and all the network connections must be closed. The LMA performs the instructions in the control message, i.e. closes all the network connections to the user equipment. After the instructions have been executed, the LMA sends an acknowledgement back to indicate which actions have been performed. Thus, the closing of all network connections is done using only one message exchange and thereby saving signalling in the Core Network.
Claims12
Method for closing multiple network connections to at least one user equipment when the at least one user equipment is detached,
- characterized in that the method comprises the following steps:
- receiving a control message in a local mobility anchor, LMA, node, the control message comprising instructions to close the multiple network connections,
- reading the control message in the LMA,
- closing the multiple network connections to the user equipment,
- sending an acknowledgement to an external node.
Method for closing multiple network connections to at least one user equipment, characterized in that the method comprises the following steps:
- detecting a detached user equipment
- deciding to close the user equipment's network connections,
- sending a control message to a local mobility anchor, LMA, the control message comprising instructions to close the multiple network connections,
- receiving an acknowledgement from the LMA.
A communication node in a telecommunications network arranged to close multiple network connections associated with at least one user equipment when the at least one user equipment is detached,
- said node comprising a processor arranged to execute instruction sets stored in a memory, the processor is arranged to receive a control message through a communication interface, read the message, close the multiple network connections to the user equipment and to send an acknowledgement to an external node.
A system comprising a first node (4, 6) and second node (5),
- the first node is arranged to be connected to the second node (5) via multiple network connections (7),
- the first node (4, 6) comprising a MAG or a PCRF and the second node (5) comprising a LMA,
- the first node (4, 6) is arranged to send a control message (220, 110) to the second node (5), the control message comprising instructions to close the multiple network connections (7),
- the second node (5) is arranged to receive and read the control message, to close the multiple network connections (7) and to send an acknowledgement (140, 230) to the first node (4, 6).
