Method and apparatus for establishing multicast groups
First Claim
1. A method, comprising:
- propagating, from a multicast manager toward a server, a registration request including a multicast signaling address associated with a multicast signaling group, the multicast signaling group comprising the multicast manager and a plurality of user devices;
receiving, at the multicast manager, a request of one of the user devices to establish a multicast group, wherein the request of the one of the user devices to establish the multicast group is received via a multicast using the multicast signaling address of the multicast signaling group; and
propagating, from the multicast manager, a response intended for the one of the user devices, the response indicative as to whether the multicast group has been created in response to the request of the one of the user devices to establish the multicast group.

Abstract
The invention includes a method and apparatus for dynamically establishing a multicast group. The method includes receiving, from a first user device, a request to establish a multicast group including a plurality of parameters adapted for establishing the multicast group, obtaining a multicast address for the multicast group, and establishing the multicast group using the assigned multicast address and the parameters. The parameters include at least one multicast group definition parameter and at least one multicast session description parameter. The multicast address and at least a portion of the parameters are adapted for being provided to a second user device to enable the second user device to dynamically join the multicast group.

10. An apparatus, comprising:
-
a processor; and a memory communicatively connected to the processor, the memory having stored thereon instructions which, when executed by the processor, cause the processor to; propagate, from a multicast manager toward a server, a registration request including a multicast signaling address associated with a multicast signaling group, the multicast signaling group comprising the multicast manager and a plurality of user devices; receive, at the multicast manager, a request of one of the user devices to establish a multicast group, wherein the request of the one of the user devices to establish the multicast group is received via a multicast using the multicast signaling address of the multicast signaling group; and propagate, from the multicast manager, a response intended for the one of the user devices, the response indicative as to whether the multicast group has been created in response to the request of the one of the user devices to establish the multicast group.

11. A method, comprising:
-
receiving, at a server, a registration request of a multicast manager, the registration request including a multicast signaling address associated with a multicast signaling group, the multicast signaling group comprising the multicast manager and a plurality of user devices; receiving, at the server, a request of one of the user devices to establish a multicast group; and multicasting the request of the one of the user devices to establish the multicast group from the server using the multicast signaling address of the multicast signaling group. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
