Abstract

There is provided mechanisms for multimedia broadcast multicast service (MBMS) bearer handling in a group communications system. A method is performed by a control node. The method comprises obtaininga need for a new MBMS bearer to be activated. The method comprises activating the new MBMS bearer. The method comprises announcing MBMS bearer identity and complementary service announcement information of the new MBMS bearer on an already announced MBMS bearer, thereby announcing the new MBMS bearer.

Description

technical field [0001] The embodiments given herein relate to Multimedia Broadcast Multicast Service (MBMS) bearer handling, and more particularly to methods, control nodes, client nodes, computer programs, and methods for MBMS bearer handling in group communication systems Computer Program Products. Background technique [0002] In communication networks, achieving good performance and capacity can be challenging for a given communication protocol, its parameters, and the physical environment in which the communication network is deployed. [0003] Examples of applications available in some communication systems include group communication services. In general, group communication means that the same information or media is delivered to multiple client nodes. In a group communication system (eg, a push-to-talk (PTT) system), client nodes receiving the same media form a client node group. These client nodes can be located in different locations. If many client nodes are ...
