Abstract
A wireless client terminal includes an application module, a service mapping module, and an address determination module. The application module determines first and second services requested by applications. The service mapping module stores a table that maps services to access point names. Each access point name identifies a respective packet data network. The address determination module transmits an address request message, including access point names corresponding to the services, to a media access gateway and receives an address response message. The address determination module determines first and second addresses based on address information in the address response message. The application module transmits a first packet to the media access gateway. The source address of the first packet is set to the first address when the first packet is related to the first service and to the second address when the first packet is related to the second service.
