In view of the problems in the prior art, the embodiment of the present invention provides a notification scheme for an MBMS capability, and the processing principle of the scheme includes: the DRNC receives a radio link setup request message from the SRNC, where the radio link setup request The message carries the MBMS bearer service list cell; the DRNC sends a radio link setup response message to the SRNC, where the radio link setup response message indicates whether the DRNC supports the MBMS by carrying the activated MBMS bearer service list cell. Let the SRNC know the MBMS capability of the DRNC cell, so as to make a correct decision, and establish a radio link that conforms to the DRNC 'J, the area MBMS capability. It should be noted that, in the case of no conflict, the embodiments and examples in the present application The present invention may be described in detail with reference to the accompanying drawings in conjunction with the embodiments. In the following embodiments, the steps shown in the flowchart of the accompanying drawings may be in the form of a set of computer-executable instructions. Executed in a computer system, and although the logical order is shown in the flowchart, in some cases The steps shown or described may be performed in an order different from the ones herein. Method Embodiments The present invention provides a method for notifying MBMS capabilities, and FIG. 2 is a flowchart of a method for notifying MBMS capabilities according to an embodiment of the present invention. As shown in FIG. 2, the method includes: Step S202: The DRNC receives a radio link setup request message from the SRNC, where the radio link setup request message carries an MBMS bearer service list cell, and the DRNC can also receive the message from the DRNC. The radio link of the SRNC adds a message, which does not need to carry the MBMS bearer service list cell. In an actual application, if the UE currently activates the MBMS service, the first radio link setup request (RADIO LINK SETUP REQUEST) message may be used. The MBMS Bearer Service List cell, that is, the MBMS bearer service list cell, fills in the currently activated MBMS service. Step S204: The DRNC sends a radio link setup response message to the SRNC, where the message is in response to the radio link setup request message. The radio link setup response message indicates the DRNC by carrying an activated MBMS? service list cell. If the MBMS is supported, the DRNC may also send a radio link add response message to the SRNC, the message being responsive to the radio link add message, wherein the radio link setup response message indicates whether the DRNC supports the bearer by carrying the activated MBMS bearer service list cell. MBMS. Corresponding to the above operation, if the cell of the DRNC does not support MBMS, the radio link establishment response (RADIO LINK SETUP RESPONSE), the wireless link boost port The Active MBMS Bearer Service List cell is not carried in the RADIO LINK ADDITION RESPONSE message. After receiving the response message, the SRNC can determine whether the DRNC cell supports MBMS according to whether the message carries the Active MBMS Bearer Service List cell. The MBMS carrying service list cell may carry one or more activations.

The MBMS service information, the activated MBMS service list cell may carry information indicating whether the DRNC supports the MBMS service that needs to be activated. In an actual application, if the UE currently activates the MBMS service, the currently activated MBMS service is filled in the MBMS Bearer Service List cell in the first RADIO LINK SETUP REQUEST message. If the DRNC cell supports MBMS, but some or all of the requested MBMS services are not sent in the cell, that is, the cell supports MBMS but some MBMS services are pre-configured to be unsupported, the radio link setup response (RADIO LINK SETUP RESPONSE) In the Active MBMS Bearer Service List cell in the RADIO LINK ADDITION RESPONSE message, the transmission mode (Transmission Mode) of each MBMS service that is not sent, that is not supported, is filled in as "No". Offer ( Not Provided ) ". After receiving the foregoing radio link setup response or the radio link addition response message, the SRNC can know that the DRNC cell supports the MBMS capability by using the Active MBMS Bearer Service List cell carried in the message; and further can be based on the Active MBMS Bearer Service List letter. The transmission mode of the MBMS service in the meta-determination determines which MBMS services in the radio link setup request message or the radio link increase request message are supported by the cell. Step S206: The SRNC processes the established or newly added radio link, where the established or newly added radio link includes: a radio link established in a case where the DRNC does not support the MBMS, or supports the MBMS in the DRNC but does not support A wireless link established for the transmission of unsupported MBMS services in the case of some MBMS services that need to be activated. If the established or added wireless link 7 carries the MBMS service, the wireless link is deleted; if the established or added wireless link does not carry the MBMS service, the wireless link is reserved, but the high speed downlink shared channel is rejected. The serving cell migrates to the wireless link. In practical applications, the SRNC may delete an unreasonable wireless link or may not allow subsequent HS-DSCH service link migration. If the newly added radio link carries an unsupported MBMS service, for example, the MBMS service uses a Dedicated Channel (DCH) bearer, the new link needs to be deleted. For example, the MBMS service uses high-speed downlink sharing. The channel (High Speed Downlink Shared Channel, HS-DSCH for short) is carried, and the current service link is on the SRNC side. This new wireless link does not need to be deleted, but the subsequent service link cannot be migrated to the DRNC side. , The new wireless link cannot be used. In summary, whether the radio link used to carry the MBMS service is established or retained must be compatible with whether the DRNC cell has MBMS support capability and the DRNC supports the specific MBMS service. The implementation process of the embodiment of the present invention will be described in detail below with reference to examples. Example 1 In this example, the UE currently includes MBMS services in its current service. 3 is a service flow diagram of a method for notifying an MBMS capability according to the first embodiment of the present invention. As shown in FIG. 3, the service flow includes the following steps:

301. The cell 1 report measurement report 1A on the DRNC cell increases the radio link that the UE transits to the SRNC through the DRNC according to the current quality of the cell.

302. The SRNC does not know the MBMS support capability of the DRNC cell, attempts to add the DRNC 'J, the zone to the active set, and sends a radio link setup message to the DRNC. Fill in the MBMS Bearer Service List cell with the list of MBMS services currently activated by the UE.

303. The DRNC sends a radio link setup response to the SRNC. Since the DRNC cell does not support MBMS, the Active MBMS Bearer Service List cell is not carried in the response message.

After the SRNC ^ owes a radio link setup response, since the response does not have an Active MBMS Bearer Service List cell, it is known that the cell does not support MBMS. Example 2 In this example, the current service of the UE includes the MBMS service. 4 is a service flow diagram of a method for notifying the MBMS capability according to the second embodiment of the present invention. As shown in FIG. 4, the business process includes the following steps:

401. The cell 1 report measurement report 1A on the DRNC cell increases the radio link that the UE transits to the SRNC through the DRNC according to the current quality of the cell.

402. The SRNC does not know the MBMS support capability of the DRNC cell, and attempts to add the DRNC cell to the active set. Because the link to be established is not the first link established across the Iur port, the SRNC sends a radio link to the DRNC. The message, the radio link addition message may not carry the MBMS bearer to establish a link list cell, and the cell is carried when the SRNC first sends a radio link setup request message to the DRNC, and is saved by the DRNC to the local to be followed. Make use.

403. The DRNC sends a wireless link booster response to the SRNC. Since the DRNC cell does not support MBMS, the Active MBMS Bearer Service List cell is not carried in the response message. After the SRNC receives the wireless link add response, because the response does not have an Active MBMS Bearer Service List cell, it is known that the cell does not support MBMS. Example 3 In this example, the current service of the UE includes the MBMS service. FIG. 5 is a service flow diagram of a method for notifying an MBMS capability according to Example 3 of the present invention. As shown in FIG. 5, the service flow includes the following steps: 501, celll 4艮 measurement 4 1 1A on the DRNC cell, According to the current quality of the cell, the radio link that the UE transits to the SRNC through the DRNC is increased.

502. The SRNC does not know the MBMS service support capability of the DRNC cell, attempts to add the DRNC 'J, the zone to the active set, and sends a radio link setup message to the DRNC. Fill in the MBMS Bearer Service List cell with the list of MBMS services currently activated by the UE. 503. The DRNC sends a radio link setup response to the SRNC. Because the DRNC cell supports

MBMS, so the response message carries the Active MBMS Bearer Service List cell. However, some or all of the MBMS services in the request message are not sent in the DRNC cell, that is, the DRNC cell does not support certain MBMS services, and therefore, each MBMS service that is not transmitted, that is, the MBMS service that the DRNC does not support is not supported. The transmission mode is filled in as "Not Provided". After the SRNC receives the radio link setup response, because the response carries the Active MBMS Bearer Service List cell, it knows that the DRNC cell supports MBMS capability; further according to the transmission mode of the MBMS service. , can know which MBMS services in this cell support request. Example 4 In this example, the current service of the UE includes the MBMS service. Figure 6 is a service flow diagram of the MBMS capability notification method according to Example 4 of the present invention. As shown in Figure 6, the service flow includes the following steps:

601. The celll reports the measurement report 1A on the DRNC cell, and according to the current quality of the cell, increases the radio link that the UE transits to the SRNC through the DRNC. 602. The SRNC does not know the MBMS service support capability of the DRNC cell, and attempts to add the DRNC cell to the active set. Because the link to be established is not the first link established across the Iur port, all the SRNCs send the wireless chain to the DRNC. The road addition message, the radio link addition message may not carry the MBMS bearer setup link list cell, and the cell is carried when the SRNC first sends a radio link setup request message to the DRNC, and is saved to the local by the DRNC. For later use.

603. The DRNC sends a radio link increase response to the SRNC. Because the DRNC cell supports MBMS, the response message carries the Active MBMS Bearer Service List cell. However, some or all of the MBMS services in the request message are not sent in the DRNC cell, that is, the DRNC cell does not support certain MBMS services, and therefore, each MBMS service that is not transmitted, that is, the MBMS service that the DRNC does not support is not supported. The transmission mode is filled in as "Not Provided". After the SRNC receives the radio link setup response, because the response message carries the Active MBMS Bearer Service List cell, it knows that the DRNC cell supports MBMS capability; further according to the MBMS service transmission. Mode, able to know which MBMS services in this cell support request. Example 5 In this example, the SRNC learns that the DRNC cell does not support the MBMS service through the radio link setup/increment response message of the Iur port. 7 is a service flow diagram of radio link deletion in the case of DCH bearer according to Example 5 of the present invention. As shown in FIG. 7, the service flow includes the following steps: 701. After the SRNC learns that the DRNC cell does not support MBMS, The previously established wireless link carries the MBMS service and decides to delete the previously established unreasonable wireless link. Therefore, the SRNC sends a RADIO LINK DELETION REQUEST message to the DRNC.

702: After successfully deleting the unreasonable wireless link, the DRNC returns a RADIO LINK DELETION RESPONSE message to the SRNC. Example 6 In this example, the SRNC learns that the DRNC cell does not support the MBMS service through the radio link setup/increment response message of the Iur port. 8 is a service flow diagram of a service link migration without using a HS-DSCH bearer in accordance with Example 6 of the present invention. As shown in FIG. 8, the service flow includes the following steps: 801, DRNC cell celll 4 艮 4 1 1 。.
