1. A communication system for providing a wireless terminal with access to a network, the wireless terminal storing an identification number for accessing a first network including a first U-plane gateway, the communication system being configured to:
receive a connection initiation request from the wireless terminal while the wireless terminal is located in a second service area of a second network, the second service area being different from a first service area of the first network;
select, in response to the connection initiation request, a third U-plane gateway of a third network connected to the second network, the third U-plane gateway being distinct from the first U-plane gateway of the first network; and
send a gateway ID of the third U-plane gateway toward the second network.
