A user equipment (UE) attaches to a first access network, intending to access a packet data network (PDN) via a telecommunications system, and is assigned a PDN System Architecture Evolution (SAE) Gateway (GW). The identity of the PDN SAE GW is registered so that, if the UE attaches to another access network, triggering a new attach procedure, the identity is retrieved. A determination is then made whether the previously-assigned PDN SAE GW may be used for the present communications and, if so, it is reassigned. The identity of the PDN SAE GW is registered in an anchor node, which is in a preferred embodiment a Home Subscriber Server (HSS). If the previously-assigned PDN SAE GW cannot be used, or if the PDN SAE GW must be changed, then the communication is reassigned to a new PDN SAE GW.
A method of providing access to an external network via a telecommunications system coupled to a plurality of access networks and coupled to the external network though a gateway pool, said method characterized by the steps of:
A system for providing UE access to an external network via a multi-access telecommunications system, said system characterized by:
In a multi-access telecommunications system, an anchor node for facilitating communications between a UE and an external network through a gateway, characterized by being arranged to register an identifier associated with the gateway upon receiving a registration message and to transmit the gateway identifier to a control plane entity during an attach procedure.
