MBMS bearer establishment reconfiguration and release
View Patent ↗The invention provides for a method of MBMS bearer control in a mobile radio communications network by way of NAS signaling, the method including employing a NAS signal for the control of a plurality of MBMS bearers and so as to allow for bearer establishment, reconfiguration and release in a signal step.
1. A method of Multimedia Broadcast Multicast Services (MBMS) bearer control in a mobile radio communications network by way of Non Access Stratum (NAS) signaling, the method including employing an NAS signal for the control of a plurality of MBMS bearers.
2. The method as claimed in claim 1 wherein the control comprises establishment of one of the MBMS bearers.
3. The method as claimed in claim 1 , wherein the control comprises a reconfiguration of one of the MBMS bearers.
4. The method as claimed in claim 1 , wherein the control comprises a release of one of the MBMS bearers.
5. The method as claimed in claim 1 , wherein the NAS signaling comprises a session management signaling.
6. The method as claimed in claim 5 , wherein the session management signaling comprises a session management control request signal.
7. The method as claimed in claim 5 , wherein the session management signaling comprises a session management control response signal.
8. The method as claimed in claim 1 and arranged for multiple MBMS Evolved Packet System (EPS) bearer control by way of the NAS signal.
9. The method as claimed in claim 8 , wherein the NAS signal includes a list of MBMS EPS bearers.
10. The method as claimed in claim 8 , wherein the NAS signal includes a list of MBMS EPS bearers in dedicated MBMS bearer signal messages sent between a serving gateway and Mobile Management Entity (MME) entities.
11. The method as claimed in claim 1 , and arranged for multiple MBMS bearer service control by way of a NAS signal.
12. A mobile radio communications device for operation within a mobile radio communication network and arranged to offer Multimedia Broadcast Multicast Services (MBMS) bearer control by way of Non Access Stratum (NAS) signaling, the device being arranged to provide an NAS signal for the control of a plurality of MBMS bearers.
13. The device as claimed in claim 12 and arranged such that the NAS signaling comprises session management signaling.
14. The device as claimed in claim 12 and arranged for multiple MBMS Evolved Packet System (EPS) bearer control by way of the NAS signal.
15. The device as claimed in claim 12 , arranged for multiple MBMS bearer services controlled by way of the NAS signal.
16. The device as claimed in claim 12 , and arranged to be responsive to a bearer control request signal as received from the mobile radio communication network.
17. A mobile radio communication network device for operation with a mobile radio communications network and arranged to offer Multimedia Broadcast Multicast Services (MBMS) bearer control by way of Non Access Stratum (NAS) signaling, the network device being arranged to receive and/or provide an NAS signal for the control of a plurality of MBMS bearers.
18. The network device as claimed in claim 17 wherein the NAS signaling comprises session management signaling.
19. The network device as claimed in claim 17 and arranged for multiple MBMS Evolved Packet System (EPS) bearer control by way of the NAS signal.
20. The network device as claimed in claim 17 and arranged for multiple MBMS bearer services control by way of the NAS signal.
21. The network device as claimed in claim 17 and arranged to deliver the NAS signal to a mobile radio communications device such as a mobile radio communications device for operation within a mobile radio communication network and arranged to offer MBMS bearer control by way of NAS signaling, the device being arranged to provide an NAS signal for the control of a plurality of MBMS bearers, and to receive a NAS signal for the control of a plurality of MBMS bearers from a Mobile Management Entity (MME) within the mobile radio communication network.
