Patent number: 11184940Abstract: 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.Type: GrantFiled: June 12, 2017Date of Patent: November 23, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Magnus Tränk, Joakim Åkesson
