摘要： The disclosure relates to methods at a wireless communication system, a wireless communication device, a network communication node, and a control node, respectively, for bearer control in a wireless communication system (100). Specifically, the method comprises determining (S11), by the WCD or the network communication node, whether the number of radio bearers concurrently active for the WCD is at least one of: equal to a threshold value and above the threshold value. If the threshold is reached, then the WCD or the network communication node transmits (S12), towards the control node (300), a first status message indicative of that the number of radio bearers concurrent active has reached the threshold value. The first status message is received by the control node and in response to the reception (S21) of the message the control node determines (S22), based on the first status message, whether an MBMS bearer is to be activated. Further, when it is determined (S22) that the MBMS bearer is to be activated, the control node activates (S23) the MBMS bearer. Corresponding computer programs, computer program products, arrangements, and devices are also disclosed.

摘要： The present application generally relates to wireless communication technology. More particularly, the present application relates to a method and apparatus for providing service continuity for Multicast and Broadcast Service (MBS). The present application also relates to computer program product adapted for the same purpose. According to one embodiment of the present application, a method in a first RAN node for providing service continuity for Multicast and Broadcast Service (MBS) comprises: receiving (510) from a UE a request for retransmitting one or more missing Packet Data Units (PDUs) in MBS data associated with an MBS session previously transmitted from a second RAN node to the UE; and handling (520) retransmission of the missing PDUs based on the request.

摘要： Embodiments herein relate to a method performed by a network node (102, 103) in a telecommunication network providing a multicast transmission to a group of devices residing in a cell of the telecommunication network. The network node (102, 103) monitors a congestion level for communication, and, if the congestion level reaches a first threshold, the network node orders for at least one device (106) in a RRC connected mode to be released from the RRC connected mode to an RRC idle mode or an RRC inactive mode, thereby disabling a capability of the at least one device (106) to provide one or more re-transmission requests while keeping an ability of the at least one device (106) to further receive the multicast transmission.

摘要： A GC server initiates the activation of a multicast bearer (e.g., MBMS bearer) in a certain area as soon as a congestion indication is received for the area, and sets-up GC calls in confirmed mode during the time period required for activating the multicast bearer. When the multicast bearer becomes available, the GC server may notify GC clients in the area that the multicast bearer is available and use the multicast bearer to transmit call data.
