Abstract

The present invention provides for a method of controlling switching between dedicated radio resources of the mobile radio communications network including sending an RRC massage to UE within the network requesting both RB release and RB set-up at the user equipment, such that only a single message is required for reconfiguration sufficient to allow switching between the RB resources which, in one example, can comprise different channels of a Mobile TV service.

First claim

The invention claimed is:

1. A method, in a mobile radio communications network, the method comprising:
providing, using a first point-to-point (PTP) radio bearer (RB), a first broadcast service to a mobile radio communications device within the mobile radio communications network;
receiving, from the mobile radio communications device, a Multimedia Broadcast Multicast Service (MBMS) modification request message indicating a desired change of broadcast service; and
sending a Radio Bearer Reconfiguration Radio Resource Control (RRC) message to the mobile radio communications device,
wherein the Radio Bearer Reconfiguration RRC message serves to initiate both a release of the first PTP RB and set-up of a second PTP RB to provide a second broadcast service to the mobile radio communications device, the second broadcast service being different from the first broadcast service; and
wherein the Radio Bearer Reconfiguration RRC message comprises a radio bearer (RB) identity information element identifying the first PTP RB and an MBMS service identity information element identifying the second broadcast service.

2. The method as claimed in claim 1 , wherein the Radio Bearer Reconfiguration RRC message further comprises an MBMS session identity information element.

3. The method as claimed in claim 1 , wherein the Radio Bearer Reconfiguration RRC message is configured to change multiplexing of a Medium Access Control (MAC).

4. The method as claimed in claim 1 , wherein the Radio Bearer Reconfiguration RRC message is configured to reconfigure at least one of transport channels and physical channels for the first PTP RB on which the first broadcast service is provided.

5. The method as claimed in claim 1 , wherein at least one of the first broadcast service and the second broadcast service includes a Multimedia Broadcast Multicast Service (MBMS).

6. A method, in a mobile radio communications device of a mobile radio communications network, the method comprising:
receiving, using a first point-to-point (PTP) radio bearer (RB), a first broadcast service from a network element within the mobile radio communications network;
sending, to the network element, a Multimedia Broadcast Multicast Service (MBMS) modification request message indicating a desired change of broadcast service; and
receiving, from the network element, a Radio Bearer Reconfiguration Radio Resource Control (RRC) message,
wherein the Radio Bearer Reconfiguration RRC message serves to initiate both a release of the first PTP RB and set-up of a second PTP RB to enable the mobile radio communications device to receive a second broadcast service that is different from the first broadcast service; and
wherein the Radio Bearer Reconfiguration RRC message comprises a Radio Bearer (RB) identity information element identifying the first PTP RB and an MBMS service identity information element identifying the second broadcast service.

7. The method as claimed in claim 6 , further comprising processing the Radio Bearer Reconfiguration RRC message to initiate the release of the first PTP RB on which the first broadcast service is received and set-up the second PTP RB to enable the mobile radio communications device to receive the second broadcast service.

8. The method as claimed in claim 7 , further including sending an RB reconfiguration complete message to the network element once the first PTP RB on which the first broadcast service is received has been released and the second PTP RB on which the second broadcast service is received has been set-up.

9. The method as claimed in claim 7 , wherein the Radio Bearer Reconfiguration RRC message further comprises an MBMS session identity information element.

10. The method of claim 6 , wherein at least one of the first broadcast service and the second broadcast service includes a Multimedia Broadcast Multicast Service (MBMS).

11. A mobile radio communications device comprising:
a receiver configured to receive, using a first point-to-point (PTP) radio bearer (RB), a first broadcast service from a network element within a mobile radio communications network; and
a transmitter configured to send, to the network element, a Multimedia Broadcast Multicast Service (MBMS) modification request message indicating a desired change of broadcast service,
wherein the receiver is further configured to receive, from the network element, a Radio Bearer Reconfiguration Radio Resource Control (RRC) message,
wherein the Radio Bearer Reconfiguration RRC message serves to initiate both a release of the first PTP RB and set-up of a second PTP RB to enable the mobile radio communications device to receive a second broadcast service that is different from the first broadcast service, and
wherein the Radio Bearer Reconfiguration RRC message comprises a Radio Bearer (RB) identity information element identifying the first PTP RB and an MBMS service identity information element identifying the second broadcast service.

12. The device as claimed in claim 11 , further comprising sending an RB Reconfiguration Complete message to the mobile radio communications network.

13. The device as claimed in claim 11 , wherein the Radio Bearer Reconfiguration RRC message further comprises a Multimedia Broadcast Multicast Service (MBMS) session identity information element.

14. The device as claimed in claim 11 , wherein the Radio Bearer Reconfiguration RRC message is configured to change multiplexing of a Medium Access Control (MAC).

15. The device as claimed in claim 11 , wherein the Radio Bearer Reconfiguration RRC message is configured to reconfigure at least one of a transport channel and a physical channel for a dedicated radio resource.

16. The device as claimed in claim 11 , wherein initiating both the release of the first PTP RB and the set-up of the second PTP RB to enable the mobile radio communications device to receive a second broadcast service causes switching between channels of a Mobile Television (TV) service.

17. The device as claimed in claim 11 , further comprising:
a processor configured to process the Radio Bearer Reconfiguration RRC message to identify the first PTP RB on which the first broadcast service is received, and to extract the MBMS service identity, to identify the second broadcast service,
wherein the identified first PTP RB is released, and
wherein set up of the second PTP RB to enable the mobile radio communications device to receive a second broadcast service is based on the extracted MBMS service identity.

18. The mobile radio communications device of claim 11 , wherein at least one of the first broadcast service and the second broadcast service includes a Multimedia Broadcast Multicast Service (MBMS).

19. A network element for use within a mobile radio communications network, the network element comprising:
a transmitter configured to provide, using a first point-to-point (PTP) radio bearer (RB), a first broadcast service to a mobile radio communications device within the mobile radio communications network; and
a receiver configured to receive, from the mobile radio communication device, a Multimedia Broadcast Multicast Service (MBMS) modification request message indicating a desired change of broadcast service,
wherein the transmitter is further configured to send a Radio Bearer Reconfiguration Radio Resources Control (RRC) message to the mobile radio communications device,
wherein the Radio Bearer Reconfiguration RRC message serves to initiate both a release of the first PTP RB and set-up of a second PTP RB to provide a second broadc
