Abstract
A method for a User Equipment, UE, of a wireless network is disclosed. The method at the UE comprises receiving scrambling information associated with the MBS session; receiving a configuration message comprising an MBS configuration for continuing receiving MBS data from the previously joined MBS session, the MBS configuration being at least partially scrambled; and performing an unscrambling process on the received MBS configuration using the received scrambling information. A method at the base station is also disclosed.
Claims44
A method for a User Equipment, UE, of a wireless network, for receiving multicast and broadcast service, MBS, data, the UE having previously joined an MBS session, the method at the UE comprising:
- Receiving, from a base station of the wireless network, scrambling information associated with the MBS session, wherein the scrambling information comprises a higher level identifier allocated by the core network;
- Receiving, from a base station of the wireless network, a configuration message comprising an MBS configuration for continuing receiving MBS data from the previously joined MBS session, the MBS configuration being at least partially scrambled;
- and
- performing an unscrambling process on the received MBS configuration using the received scrambling information.

A method at a base station of a wireless network controlling a cell on which one or more UE are camping or served, the method comprising:
- performing a scrambling process on an MBS configuration for continuing receiving, by a UE, MBS data from an MBS session previously joined by said UE, wherein the scrambling process is performed using scrambling information previously provided to said UE, such that the MBS configuration is at least partially scrambled, wherein the scrambling information comprises a higher level identifier allocated by the core network;
- and
- sending, to the one or more UE, a configuration message comprising the at least partially scrambled MBS configuration.
