Method and apparatus for establishing a group call in a multiple wireless technology communication system
First Claim
1. A method for implementing a group call, the method comprising:
- receiving, by an infrastructure device associated with a first originating network from a mobile device, a group call request, wherein the first originating network is one of a narrowband network and a broadband network;
in response to receiving the group call request, determining, by the infrastructure device, that insufficient network resources are available in the first originating network for allocation to the mobile device for the group call; and
in response to determining that insufficient network resources are available, arranging, by the infrastructure device, to set up an originating leg of the group call for the mobile device in a second originating network, wherein the second originating network is the other network of the narrowband network and the broadband network.

Abstract
A communication system is provided that sets up a group call, originated in a first originating network, in a second originating network when insufficient resources are available in the first originating network, wherein the first originating network is one of a narrowband network and a broadband network and the second originating network is the other network of the narrowband and broadband networks. An infrastructure device of the first originating network receives a first group call request from an originating mobile device and, in response to receiving the request, determines that insufficient resources are available in the first originating network for allocation to the mobile device for the group call. In response to determining that insufficient network resources are available, the infrastructure device arranges to set up an originating leg of the group call for the originating mobile device in the second originating network.

17. A system for implementing a group call in a wireless communication system comprising a plurality of narrowband networks and a plurality of broadband networks, the system comprising:
-
a narrowband network infrastructure device that is configured to; receive, from an originating mobile device, a first group call request that identifies a target mobile device; in response to receiving the first group call request, determine that insufficient resources of a first narrowband network of the plurality of narrowband networks are available for allocation to the mobile device for the group call; and in response to determining that insufficient narrowband network resources are available, convey a second group call request to a broadband Group Call Server; one or more broadband Group Call Servers that are configured to; receive the second group call request; establish an originating leg of the group call with the originating mobile device in a first broadband network of the plurality of broadband networks; establish a terminating leg of the group call with the target mobile device in a second broadband network of the plurality of broadband networks; and wherein the narrowband network infrastructure device further is configured to establish a terminating leg of the group call with the target mobile device in a second narrowband network of the plurality of narrowband networks. - View Dependent Claims (18)
