Technique for IP communication among wireless devices

A General Packet Radio Service Network, comprising:

• at least one radio access network for radio access to mobile terminal users;
• and
• at least one service node in the network coupled to the at least one access network for caching from a sending a mobile terminal user an IP packet having an IP destination address, the service node checking the destination IP address to determine if the packet is destined for at least one recipient mobile terminal user served by the at least one access network, and if so, then routing the packet to the recipient mobile terminal user identified by the destination IP address in the packet.

For use with a General Packet Radio Service Network having at least one radio access network for radio access to mobile terminal users,

• at least one service node for coupling to the one access network for caching a from a sending a mobile terminal user an IP packet having an IP destination address, the service node checking the destination IP address to determine if the packet is destined for at least one recipient mobile terminal user served by the at least one network, and if so, then routing the packet to the recipient mobile terminal user identified by the destination IP address in the packet.
