Selective packet voice trigger use in a wireless communication network

摘要

Embodiments disclosed herein provide systems and methods for selective use of a packet voice trigger in a wireless access network. In a particular embodiment, a method provides receiving a call request for a call from a wireless device. The method further provides determining a location of the wireless device and processing an identifier for the wireless device to retrieve a device profile for the wireless device. If the device profile indicates that a trigger should be used for packet voice communications, then the method provides determining whether the trigger should be disarmed based on a quantity of the plurality of different access networks available to the wireless device at the location. If the trigger is armed, transfer the call request for delivery to the packet voice server to set up the call and, if not, process the call request in the wireless access network to set up the call.

主权项

1. A method of operating a wireless access network, wherein the wireless access network comprises one of a plurality of different wireless access networks and wherein a packet voice server interoperates with the plurality of different wireless access networks, comprising:
receiving a call request for a call from a wireless communication device that is capable of exchanging packet voice communications over different access networks; determining a geographic location of the wireless communication device; processing an identifier for the wireless communication device to retrieve a device profile for the wireless communication device; if the device profile indicates that the wireless communication device should use a trigger for packet voice communications to be serviced through the packet voice server, determining whether the trigger should be disarmed based on a quantity of the plurality of different access networks available to the wireless communication device at the geographic location of the wireless communication device, wherein the trigger is disarmed if there are no additional wireless access networks available to the wireless communication device at the geographic location based on a table that indicates a trigger disarmament state for the wireless communication device at the geographic location; if the trigger is armed, transferring the call request for delivery to the packet voice server to set up the call; and if the trigger is disarmed, processing the call request in the wireless access network to set up the call.
