A system and method are provided for using differentiated telephone numbers to determine whether to perform a vocoder bypass. In an exemplary embodiment, a mobile station may call a terminating node. An intermediate entity may search an identifier of the terminating node for a predetermined aspect. If the predetermined aspect is found, the terminating node may be a mobile station, and the intermediate entity may perform a vocoder bypass. If the predetermined aspect is not found, the terminating node may be a non-mobile station, and the intermediate entity may perform vocoding.

Method and system for vocoder bypass using differentiated telephone numbers

A method for handing off a wireless communication session between a first radio network and a second radio network. The method includes handing off the wireless communication session from the first wireless communication to the second radio network based on a first trigger. The method also includes handing off the wireless communication session from the second wireless communication to the first radio network based on a second trigger, wherein the second trigger is different than the first trigger.

Method and system for asymmetric handoff of wireless communication sessions

A method and system for sending a voice message in a wireless communication network. A mobile station may encode an audio speech signal into a voice mail message and send the voice mail message through a wireless network to a voice mail server. An entity of the wireless network may first receive the message and determine if an intended recipient is another mobile station. If so, the entity may simply forward to voice mail message on to the voice mail server. If not, the entity may transcode the voice mail message into another format and then send the formatted voice mail message to the voice mail server, which stores the voice mail message for later delivery to the intended recipient.

Method and system of sending a voice message in a wireless communication network

A system and method are provided for using electronic serial numbers (ESNS) to determine whether to perform vocoder bypass. In an exemplary embodiment, a terminal device may share a common mobile identification number (MIN) with other terminal devices. The terminal device may answer a page and provide its ESN to an intermediate entity. The intermediate entity may query a database to determine whether the answering terminal device is a mobile station. The intermediate entity may perform vocoding if the answering terminal device is a non-mobile station, or vocoder bypass if the answering terminal device is a mobile station.
