Abstract

The disclosure discloses a method for determining the resumption of a suspended Multimedia Broadcast Multicast Service (MBMS), which comprises: when the MBMS service is intended to be resumed after being suspended, triggering a network side to send an MBMS Control Channel (MCCH) notification message for indicating a change of an MCCH message; determining, by User Equipment (UE), that the suspended MBMS service is resumed by reading the MCCH notification message and a changed MCCH message. The disclosure also provides a device and a UE for determining the resumption of an MBMS. The technical solution of the disclosure provides a better supplement for reception of an MBMS service in a present MBMS system, and further improves Quality of Service (QoS) of the MBMS system and a UE user'"'"'s experience.

Claims

1. A method for determining resumption of a suspended Multimedia Broadcast Multicast Service (MBMS), comprising:

when the MBMS service is intended to be resumed after being suspended, triggering a network side to send an MBMS Control Channel (MCCH) notification message for indicating a change of an MCCH message; and

determining, by User Equipment (UE), that the suspended MBMS service is resumed by reading the MCCH notification message and a changed MCCH message,

wherein the MBMS service being suspended does not include an MBMS service interruption caused by the network side sending an MBMS session stop request message, or an MBMS service interruption caused by the UE'"'"'s own behaviour.

4. The method according to claim 1, wherein after determining, by the UE, that the suspended MBMS service is resumed by reading the MCCH notification message and the changed MCCH message, the method further comprising:

the UE resuming reception of the MCCH and receiving the resumed MBMS service again.

5. The method according to claim 1, wherein, when the MBMS service is suspended, the network side suspends the MCCH notification message corresponding to the MBMS service.

6. The method according to claim 1, wherein the MCCH notification message is an MCCH change notification message;

and the network side is an evolved NodeB (eNB).

19. The method according to claim 4, wherein the MCCH notification message is an MCCH change notification message;

and the network side is an evolved NodeB (eNB).

20. The method according to claim 5, wherein the MCCH notification message is an MCCH change notification message;

and the network side is an evolved NodeB (eNB).

2-3. -3. (canceled)

7. A method for determining resumption of a suspended MBMS service, comprising:

a UE continuing reading an MCCH periodically after determining that the MBMS service is suspended, and determining that the suspended MBMS service is resumed when the MCCH contains indication information of the suspended MBMS service;

wherein the MBMS service being suspended does not include an MBMS service interruption caused by a network side sending an MBMS session stop request message, or an MBMS service interruption caused by the UE'"'"'s own behaviour.

9. The method according to claim 7, wherein after the UE determining that the suspended MBMS service is resumed, the method further comprising:

receiving, by the UE, the resumed MBMS service again.

8. (canceled)

10. A device for determining resumption of a suspended MBMS service, comprising:

a resumption unit and an indication unit that are located at a network side, and a receiving unit and a determination unit that are located at a UE side, wherein

the resumption unit is configured to resume the suspended MBMS service and trigger a sending unit;

the sending unit is configured to send an MCCH notification message for indicating a change of an MCCH message

the receiving unit is configured to receive the MCCH notification message and a changed MCCH message;

the determination unit is configured to determine that the suspended MBMS service is resumed according to the MCCH notification message and the changed MCCH message.

12. The device according to claim 10, further comprising:

a reading unit configured to resume reception of the MCCH after the determination unit determines that the suspended MBMS service is resumed and to receive the resumed MBMS service again using the receiving unit.

11. (canceled)

13. A device for determining resumption of a suspended MBMS service, comprising:

a first determination unit, a reading unit and a second determination unit, wherein

the first determination unit is configured to trigger a reading unit after determining that the MBMS service is suspended;

the reading unit is configured to continue reading an MCCH periodically;

the second determination unit is configured to determine that the suspended MBMS service is resumed when determining that the MCCH contains indication information of the suspended MBMS service.

14. The device according to claim 13, further comprising:

a receiving unit configured to receive the resumed MBMS service again after the second determination unit determines that the suspended MBMS service is resumed.

16. A UE, having a device for determining resumption of a suspended MBMS service described in claim 13.

21. A UE, having a device for determining resumption of a suspended MBMS service described in claim 14.

15. A UE having an MBMS information reception capacity, comprising a receiving unit and a determination unit, wherein

the receiving unit is configured to receive an MCCH notification message and an MCCH message;

the determination unit is configured to determine that a suspended MBMS service is resumed.
