Apparatus, and Associated Method, for Multicasting Data in a Radio Communications System
First Claim
1. An apparatus for selectably facilitating communication of multicast data from a data source to a first mobile user_endpoint and at least a second mobile user endpoint belonging to a multicast group, through a radio access network (RAN) in a packet-based multi-user radio communication system, wherein the radio access network defines a service area comprising at least one cell within which communication with the first and at least a second_mobile user endpoints, when positioned therein, is effectuable, said apparatus comprising:
- an identifier for identifying that communication of the multicast data is to be effectuated upon a common radio channel, common to both the first mobile user endpoint and the at least the second mobile user endpoint; and
a point to multi-point bearer implementer, coupled to said identifier, for implementing a multicast of the multicast data upon the common radio channel to the first and at least second mobile user endpoints, respectively, when said identifier identifies that the communication of the multicast data is to be effectuated upon the common radio channel.

Abstract
Apparatus, and an associated method, for facilitating formation of a RANcast in a radio communication system. An identifier identifies when a selected number of mobile user endpoints within a cell of a radio communication system are to receive the same multicast data. When the number exceeds a selected threshold, a RANcast is implemented by a RANcast implementer in which a common channel is used to broadcast the multicast data to all the mobile user endpoints.

17. A method of for selectably facilitating communication of multicast data from a data source to a first mobile user endpoint and at least a second mobile user endpoint, belonging to a multicast group, through a radio access network (RAN) in a packet-based multi-user radio communication system, wherein the radio access network defines a service area comprising at least one cell within which communication with the first and at least second mobile user endpoints, when positioned therein, is effectuable, said method comprising:
-
identifying that communication of the multicast data is to be effectuated upon a common radio channel, common to both the first mobile user endpoint and the at least the second mobile user endpoint; and
implementing point to multi-point bearer for implementing a multicast of the multicast data upon the common radio channel to the first and at least second mobile user endpoints, respectively, when it is identified that the communication of the multicast data is to be effectuated upon the common radio channel. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A computer program embodied in a computer-readable medium having computer-executable components configured to perform, when executed on an apparatus for selectably facilitating communication of multicast data from a data source to a first mobile user endpoint and at least a second mobile user endpoint, the following:
identifying that communication of the multicast data is to be effectuated upon a common radio channel, common to both the first mobile user endpoint and the at least the second mobile user endpoint; and
implementing point to multi-point bearer for implementing a multicast of the multicast data upon the common radio channel to the first and at least second mobile user endpoints, respectively, when it is identified that the communication of the multicast data is to be effectuated upon the common radio channel.
