Abstract
Systems and methods are described for performing a group call using a data bearer. At a core network in communication with an access node, a request to establish a group call may be received. A multicast data bearer may be established with the access node such that group call data from the core network is communicated over the multicast data bearer to the access node. Group call data may be communicated between the access node and a first wireless device and the access node and a second wireless device, wherein downlink group call data from the core network for both the first wireless device and the second wireless device is transmitted to the access node over the multicast data bearer.

A method for performing a group call with a data bearer, the method comprising:
- receiving, at a core network in communication with an access node, a request to establish a group call;
- establishing a multicast data bearer with the access node wherein group call data from the core network is communicated over the multicast data bearer to the access node;
- communicating group call data between the access node and a first wireless device and the access node and a second wireless device, wherein downlink group call data from the core network for both the first wireless device and the second wireless device is transmitted to the access node over the multicast data bearer;
- receiving, at the access node from the first wireless device, uplink data for the group call, wherein the uplink data is carried from the access node to the core network over the multicast data bearer;
- and
- preventing the second wireless device from transmitting uplink data for the group call over the multicast data bearer when the first wireless device is transmitting uplink data over the multicast data bearer.
A system for performing a group call with a data bearer, the system comprising:
- a core network comprising a processing node with a processor configured to:
- receive, at the core network that is in communication with an access node, a request to establish a group call;
- and
- establish a multicast data bearer with the access node wherein group call data from the core network is communicated over the multicast data bearer to the access node;
- the access node is configured to:
- communicate group call data between the access node and a first wireless device and the access node and a second wireless device, wherein downlink group call data from the core network for both the first wireless device and the second wireless device is transmitted to the access node over the multicast data bearer;
- receive, at the access node from the first wireless device, uplink data for the group call, wherein the uplink data is carried from the access node to the core network over the multicast data bearer;
- and
- preventing the second wireless device from transmitting uplink data for the group call over the multicast data bearer when the first wireless device is transmitting uplink data over the multicast data bearer.
