Method and system for data exchange when a call is established on a non-class A cellular endpoint

摘要

A telecommunication system and method that allow a data exchange to be initiated while a user is engaged in a voice communication using a non-class A endpoint (e.g., cellular telephone, personal digital assistant, etc.) with another party. One example method maintains a first voice communication leg to the wireless device and a second voice communication leg to the second device, inputs a request for the data exchange during the voice communication, disconnects the first voice communication leg, parks the second voice communication leg and waits for data to be transmitted to or from the wireless device. Once it is determined that the data exchange is complete, the method establishes a third voice communication leg to the wireless device, unparks the second voice communication leg and connects the second and third voice communication legs.

主权项

1. A method of initiating a data exchange for a non-class A wireless device participating in a voice communication with a second device, the method comprising:
maintaining a first voice communication leg to the wireless device and a second voice communication leg to the second device; receiving a request for the data exchange transmitted from the wireless device during the voice communication on a service other than is used for the data exchange; determining whether the wireless device has access rights to initiate the data exchange during the voice communication; and when it is determined that the wireless device has access rights to initiate the data exchange during the voice communication:
disconnecting the first voice communication leg;parking the second voice communication leg;waiting for data to be transmitted to or from the wireless device;determining that the data exchange is complete;establishing a third voice communication leg to the wireless device when it is determined that the data exchange is complete;unparking the second voice communication leg; andconnecting the second and third voice communication legs.
