Abstract:
In accordance with a first aspect of the present invention, there is provided a method of signalling in a communications network comprising a user equipment, a first radio access network, a second radio access network and a core network, the core network comprising a first packet switched network control node communicatively coupled to the first radio access network, a circuit switched network control node communicatively coupled to the first radio access network, and a second packet switched network control node communicatively coupled to the second radio access network, wherein the second packet switched network control node is capable of forming an association with the circuit switched network control node, in dependence on the user equipment performing an update to the second radio access network, to enable one or more features which employ said circuit switched network control node, the method comprising: receiving a first update of the user equipment from the first radio access network towards the first packet switched network control node; subsequent to the receipt of said first update, receiving an update of the user equipment from the second radio access network towards the second packet switched network control node; sending a context-related message from the second packet switched network control node to the first packet switched network control node, the context-related message comprising association requirement context data indicating an association requirement between the second packet switched network control node and the circuit switched network control node; and receiving a further update of the user equipment from the first radio access network towards the first packet switched network control node, wherein said context-related message is sent before said further update of the user equipment from the first radio access network is received. This has an advantage that the sending of the context-related association requirement context data is independent of the further update of the user equipment towards the first packet switched network control node. The sending of the association requirement context data may thus be reliably achieved even if the receipt of the further update causes suppression of the sending of context-related messages.

Abstract:
A method and apparatus for providing a local IP access service to a User Equipment (UE) attached to a femtocell including a Packet Data Network (PDN) gateway function in a wireless communication system. A method includes receiving a service request from a User Equipment (UE), transmitting an initial UE message including information on a local gateway to a Mobility Management Entity (MME), storing bearer information carried in an initial context setup request transmitted by the MME, receiving a Packet Data Network (PDN) connectivity request from the UE, forwarding the PDN connectivity request to the MME, receiving a create session request from the MME, and establishing a radio bearer with the local gateway, the local gateway being co-located with the femtocell.
Abstract:
The present invention relates to a mobile communication system, and to a method for managing terminal paging in the system. A paging method of a terminal is characterized by comprising the steps of: receiving, from a base station, both a local counter value for synchronization with the base station and a local ID that the base station has allocated to the terminal; synchronizing the base station and the counter using the local counter value so as to enter an idle state; and checking the local counter and a paging trigger message contained in the subframe corresponding to the local ID. According to the present invention, local IDs are each allocated to the respective multiple MTC terminals, and therefore trigger periods can be efficiently managed in a network. Further, the multiple MTC terminals can be grouped using the allocated local IDs, thus achieving advantages of an increased number of MTC terminals which can be managed in the network.
