Abstract
A method is provided of deactivating PDP Context upon transfer of a connection with a user terminal between a femtocell base station and a macrocell base station, the method comprising: the femto base station receiving a message including a first identifier of a PDP Context, altering the identifier of a PDP Context to a second identifier, and forwarding the altered message to the core network, the core network receiving a message including an identifier determines that the received identifier does not match the identifier that it expects and so deactivates the PDP Context.

A method of deactivating Packet Data Protocol, PDP, Context upon transfer of a connection with a user terminal between a femtocell base station and a macrocell base station, the method comprising:
- the femtocell base station receiving (FIG. 3:a) a message including a first identifier of a PDP Context, altering the identifier of the PDP Context to a second identifier, and forwarding the altered message to the core network,
- the core network receiving a further message including an identifier, the core network determining that the received identifier does not match the identifier that the core network expects and so deactivating the PDP Context.
A telecommunications network comprising a femtocell base station, a macrocell base station, and a core network, the femto base station being configured to receive a message including a first identifier of a PDP Context, to alter the identifier of a PDP Context to a second identifier, and to forward the altered message to the core network;
- the core network being configured to receive a message including such an identifier, to determine that the received identifier does not match the identifier that the core network expects and so to deactivate the PDP Context.
