SYSTEM AND METHOD OF GROUP CALLING IN MOBILE COMMUNICATIONS |
摘要 |
Information is retrieved from a list of members of a group call group (Fig.7). Based on the retrieved information, a group call is established between first and second mobile stations (MS). The first MS is served by a first base station controller (BSC) and the second MS is served by a second BSC. Voice data for the group call is transmitted in a multicase session. Based on a history of group calls between two points in a mobile communications network, a determination is made as to whether to establish a multicast session between the two points, e.g., in anticipation of a future group call.
