It is desirable for a user equipment (UE) 100 to be able to determine if connecting using an access point name (APN) would result in a home routed or local breakout (LBO) routed connection. With this information, the UE can decide which APNs to use for packet data network (PDN) connections e.g. to ensure that the bearers on the PDN connection are able to carry certain services which are incompatible with home routing or LBO routing, or to ensure that charging is carried out by the home or visited network, as desired (e.g. to avoid roaming fees). Alternatively, the user can be presented with the option of home routing or LBO routing for a connection. In order to provide this information to the UE, modified signalling is proposed, among others, by means of a method of operating a mobility management entity (MME) 200 in a mobile telecommunications network. The MME provides, S103, to a UE a mapping between an APN that has been or may be used by the UE to establish a connection to a PGN gateway and a routing type associated with the connection. The routing type is one of home routing and local breakout, LBO, routing. The UE is roaming in a geographical area controlled by the MME. |
