Method and system for voice calls in a wireless local area network (WLAN)

A system for providing a voice session in a micro wireless network, comprising:

• logic encoded media;
• and
• the logic operable to communicate between a micro wireless network and a service node of a macro wireless network coupled to the micro wireless network through an interface of a same type as used by a radio access network of the macro wireless network to communicate with the service node, to establish a real-time protocol communication path from the interface through a voice module of the service node to a public switched telephone network and to communicate voice traffic to the public switched telephone network through the interface and the real-time protocol communication path, wherein the voice module is operable to instruct the access router of the micro wireless network to establish real time protocol streaming connections to a gateway of the public switched telephone network associated with the macro wireless network, and wherein the voice module is further operable to connect incoming voice traffic to a vocoder that is operable to convert incoming voice traffic from a compression format of an access router of the micro wireless network to a compression format used by the public switched telephone network.

A packet data serving node (PDSN) for a wireless communication system, comprising:

• a voice module operable to establish a real-time protocol path between a router of a disjoint micro wireless network and a public switched telephone network;
• and
• a vocoding function operable to convert voice traffic received from the micro wireless network in a real-time protocol path from a mobile node format to a format for communication in a public switched telephone network, wherein the voice module is operable to instruct the access router of the micro wireless network to establish real time protocol streaming connections to a gateway of the public switched telephone network associated with the macro wireless network, and wherein the voice module is further operable to connect incoming voice traffic to the vocoder that is operable to convert incoming voice traffic from a compression format of the router to a compression format used by the public switched telephone network.
