System and method for MBMS support
First Claim
1. A method for handling a group session of a communication group, comprising:
- determining server association data for each mobile computing unit (MU) of a plurality of mobile computing units (MUs) in the communication group, wherein the server association data is indicative of a Push-To-Talk (PTT) server of a plurality of PTT servers to which the MU belongs;
determining access network association data for each MU of the plurality of MUs, wherein the access network association data is indicative of an operating area respective to a PTT server of the plurality of PTT servers which the MU is currently operating in;
determining, as a function of the server association data, a first MU of the plurality of MUs in the communication group that belongs to a first PTT server of the plurality of PTT servers and, as a function of the access network association data, that is currently operating in an operating area of a second PTT server of the plurality of PTT servers, wherein the first PTT server is a controlling PTT server for the group session of the communication group; and
determining, based on the server association data, that none of the plurality of MUs participating in the group session belongs to the second PTT server and, in response, transmitting invitation data from the first PTT server to the second PTT server to invite the second PTT server to join the group session of the communication group.

Abstract
A system and method handles a group session of a communication group. The method includes determining server association data and access network association data for each mobile unit in a communication group. The server association data indicates a first association with a Push-To-Talk (PTT) server. The access network association data indicates a second association with an operating area respective to the PTT servers. The method includes determining a first MU of the MUs in the communication group being associated with a first PTT server and associated with a MBMS operating area of a second PTT server, the first PTT server controlling the group session. When none of the MUs participating in the group session is associated with the second PTT server, the method includes inviting the second PTT server to join the group session of the communication group.

13. A system, comprising:
-
a plurality of mobile computing units (MUs) in a group session of a communication group; and a first Push-To-Talk (PTT) server controlling the group session of the communication group, the first PTT server configured to; determine server association data for each mobile computing unit (MU) of the plurality of MUs, wherein the server association data is indicative of a PTT server, of the first PTT server and a second PTT server, to which the MU belongs; determine access network association data for each MU of the plurality of MUs, the access network association data being indicative of an operating area respective to a PTT server, of the first PTT server and the second PTT server, which the MU is operating in; determine, as a function of the server association data, a first MU of the plurality of MUs that belongs to the first PTT server and, as a function of the access network association data, that operates in an operating area of the second PTT server; and determine, based on the server association data, that none of the plurality of MUs belongs to the second PTT server and, in response, transmit invitation data to the second PTT server to invite the second PTT server to join a group session of the communication group. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A controlling Push-To-Talk (PTT) server homing a communication group and handling a group session of the communication group, the PTT server comprising:
-
a processor configured to determine server association data for a plurality of mobile computing units (MUs) in the communication group, wherein the server association data is indicative of a PTT server, of the controlling PTT server and a participating PTT server, to which each mobile computing unit (MU) of the plurality of MUs belongs, the processor further configured to determine access network association data for the plurality of MUs, wherein the access network association data is indicative of an operating area respective to one of the PTT servers of the controlling PTT server and a participating PTT server in which each MU of the plurality of MUs operates; and an at least one memory device configured to store the server association data and the access network association data; wherein the processor is configured to determine, as a function of the server association data, a first MU of the MUs in the communication group that belongs to the controlling PTT server and, as a function of the access network association data, that operates in an operating area of the participating PTT server; and wherein the processor is configured to determine, based on the server association data, that none of the plurality of MUs belongs to the participating PTT server and, in response, to transmit invitation data to the participating PTT server to invite the participating PTT server to join the group session of the communication group.
