MBMS error processing method, communication node, communication system, and storage medium

1. A method for processing a Multimedia Broadcast Multicast Service (MBMS) error, comprising:

receiving indication information of the MBMS error, wherein the indication information being formed according to an error indicator of the MBMS error of network equipment, and the error indicator being extracted from MBMS Scheduling Information (MSI) sent by an Evolved Node B (eNB);

establishing a unicast bearer according to the indication information; and

sending data through the unicast bearer,

wherein the data includes received data which is being received by User Equipment (UE) through an MBMS bearer or data of interest which the UE is interested in when the MBMS error occurs,

and wherein the error indicator is born by a newly added value of the MSI or the preserved value 2043 or 2046.

2. The method according to claim 1 , wherein receiving the indication information of the MBMS error comprises:

receiving the indication information of the MBMS error from the UE or a Broadcast-Multicast Service Centre (BM-SC).

3. The method according to claim 1 , wherein the MBMS error is a network equipment fault which makes it impossible to normally send MBMS data within a specified time.

4. A method for processing a Multimedia Broadcast Multicast Service (MBMS) error, comprising:

acquiring an error indicator of the MBMS error of network equipment;

forming indication information according to the error indicator; and

sending the indication information to an Application Server (AS),

wherein the AS establishes a unicast bearer and sends data by using the unicast bearer according to the indication information,

wherein acquiring the error indicator of the MBMS error of the network equipment comprises:

extracting the error indicator from MBMS Scheduling Information (MSI) sent by an Evolved Node B (eNB),

and wherein the error indicator is born by a newly added value of the MSI or the preserved value 2043 or 2046.

5. The method according to claim 4 , wherein

acquiring the error indicator of the MBMS error of the network equipment comprises:

when the MSI, or an MSI numerical value for indicating the MBMS error is not received within a specified time, determining that the MBMS error has occurred in the network equipment and deeming automatically that the error indicator has been acquired.

6. The method according to claim 4 , wherein the network equipment is the eNB, a Multicell/Multicast Coordination Entity (MCE), a Mobility Management Entity (MME), an MBMS-GateWay (MBMS-GW) or a Broadcast-Multicast Service Centre (BM-SC).

7. The method according to claim 6 , wherein acquiring the error indicator of the MBMS error of the network equipment comprises:

acquiring, by User Equipment (UE), the error indicator of the MBMS error of the network equipment from the MSI or Radio Resource Control (RRC) signalling sent by the eNB.

8. The method according to claim 7 , wherein sending the indication information to the AS comprises:

sending, by the UE, the indication information to the AS through application layer signalling of a GC1 interface.

9. The method according to claim 6 , wherein acquiring the error indicator of the MBMS error of the network equipment comprises:

acquiring, by the BM-SC, own MBMS error to form the error indicator; or

receiving, by the BM-SC, the error indicator of the MBMS error.

10. The method according to claim 9 , wherein sending the indication information to the AS comprises:

sending, by the BM-SC, the indication information to the AS through a GC2 interface.

11. A communication node, the communication node comprising a processor and a communication interface, wherein the processor is configured to:

acquire an error indicator of a Multimedia Broadcast Multicast Service (MBMS) error of network equipment; and

form indication information according to the error indicator,

wherein the communication interface is configured to send the indication information to an Application Server (AS),

wherein the AS establishes a unicast bearer and sends data by using the unicast bearer according to the indication information,

wherein the processor is further configured to extract the error indicator from MBMS Scheduling Information (MSI) sent by an Evolved Node B (eNB),

and wherein the error indicator is born by a newly added value of the MSI or the preserved value 2043 or 2046.

12. The communication node according to claim 11 , wherein the communication node is User Equipment (UE),

and wherein the processor is further configured to, when the MSI, or an MSI numerical value for indicating the MBMS error is not received within a specified time, determine that the MBMS error has occurred in the network equipment and deem automatically that the error indicator has been acquired.

13. The communication node according to claim 11 , wherein the network equipment is the eNB, a Multicell/Multicast Coordination Entity (MCE), a Mobility Management Entity (MME), an MBMS-GateWay (MBMS-GW) or a Broadcast-Multicast Service Centre (BM-SC).

14. The communication node according to claim 13 , wherein the communication node is the UE,

and wherein the processor is further configured to acquire the error indicator of the MBMS error from the network equipment through the eNB.

15. The communication node according to claim 14 , wherein the communication interface is further configured to send the indication information to the AS through application layer signalling of a GC1 interface.

16. The communication node according to claim 13 , wherein the communication node is the BM-SC,

wherein the processor is further configured to acquire own MBMS error of the BM-SC to form the error indicator, or receive the error indicator of the MBMS error,

and wherein the communication interface is further configured to send the indication information to the AS through a GC2 interface.

17. A non-transitory computer storage medium having stored therein computer-executable instructions for executing the method according to claim 1 .

18. A non-transitory computer storage medium having stored therein computer-executable instructions for executing the method according to claim 4 .
