Description

Method, device and system for establishing radio bearer for MBMS bearer service

technical field

The present invention relates to the technical field of mobile communication, in particular to a method, device and system for establishing a wireless bearer for multimedia broadcast/multicast bearer services.

Background technique

MBMS (Multimedia Broadcast Multicast Services) refers to a point-to-multipoint service in which one data source sends data to multiple terminals. The purpose of introducing MBMS is to realize the sharing of network resources. The network includes CN (Core Network, core network) and RAN (Radio Access Network, radio access network). user terminal services.

MBMS services can be conceptually divided into two types: MBMS User Service (MBMS User Service) and MBMS Bearer Service (MBMS Bearer Service). MBMS user service refers to specific MBMS applications that end users can feel, such as mobile TV and file downloading. The MBMS bearer service refers to a service that provides bearer services for point-to-multipoint transmission of MBMS service data from a BM-SC (Broadcast Multicast Services Center) to multiple terminals. One MBMS user service can be carried by multiple MBMS bearer services, and one MBMS bearer service can also provide services for different MBMS user services.

When multiple MBMS bearer services provide services for one MBMS user service, the multiple MBMS bearer services establish bearer service transmission in the same area, and the terminal needs to receive data from all MBMS bearer services to experience the complete MBMS user service. For example, for a TV service composed of separate audio and video, the audio is transmitted on one MBMS bearer service, and the video is transmitted on another MBMS bearer service. The terminal can only watch the TV service after receiving both the audio and video.

The existing MBMS user service information and MBMS bearer service information are usually created by the BM-SC. When the MBMS bearer service needs to be established, the BM-SC initiates the MBMS session start process first, and transmits the MBMS bearer information (such as the bearer service identifier, service quality, etc.) to the CN and RAN through the MBMS session start request message. The received MBMS bearer information establishes a bearer channel for service data transmission. After the MBMS session start process ends, the RAN allocates wireless air interface resources for the MBMS bearer service according to the received MBMS bearer information, establishes a wireless bearer, and then transmits business data to the terminal.

Due to the introduction of the FLC (frequency layer convergence) function, the wireless access network may establish different MBMS bearer services corresponding to the same MBMS user service on different carriers for transmission, and to receive data of different carriers requires a terminal The ability to have multiple receivers increases the requirements for terminals, which limits the scope of application of MBMS services.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Example 1

Referring to Fig. 1, an embodiment of the present invention provides a method for establishing a radio bearer for a multimedia broadcast/multicast bearer service, including:

101: Receive an MBMS session start request message requesting establishment of a multimedia broadcast/multicast MBMS bearer service, where the MBMS session start request message includes MBMS user service information;

102: Establish a radio bearer for the requested MBMS bearer service according to the MBMS user service information.

In the embodiment of the present invention, MBMS includes MBMS in traditional mobile communication systems, E-MBMS (evolved MBMS) in LTE (Long Term Evolution, long-term evolution system), and MBMS that may evolve in the future.

The method provided in this embodiment enables the wireless access network to allocate appropriate wireless air interface resources and establish wireless bearers according to MBMS user service information, thereby improving the utilization rate of wireless air interface resources and reducing requirements on terminals.

Example 2

Referring to Fig. 2, an embodiment of the present invention provides a method for establishing a radio bearer for a multimedia broadcast/multicast bearer service, which specifically includes:

201: The BM-SC sends an MBMS session start request message to the CN, requesting to establish an MBMS bearer service, and the MBMS session start request message includes the identifier of the MBMS user service.

In this embodiment, the BM-SC may adopt any of the following two ways to include the MBMS user service identifier in the MBMS session start request message:

Mode 1: Included in the TMGI (Temperary Mobile Group Identity) in the MBMS session start request message, usually the TMGI includes the MBMS Bearer Service ID (MBMS Service ID), and the BM-SC is responsible for the MBMS Bearer Service ID in this MBMS Bearer Service ID. Divide a fixed number of bits in the MBMS user service identifier, and the MBMS bearer service identifier includes two components: MBMS user service identifier and bearer ID (Bearer ID). The bearer ID is the ID of the MBMS bearer service currently requested to be established. For example, a certain MBMS user service needs to establish 8 MBMS bearer services, and their IDs are ID1~ID8. for ID3. When the MBMS user service identifiers of multiple MBMS bearer services are the same, it indicates that the multiple MBMS bearer services correspond to the same MBMS user service. For example, the bearer identifiers of two MBMS bearer services are 2 and 3 respectively, and the MBMS user service identifiers are both 100, it can be determined that the two MBMS bearer services correspond to the same MBMS user service.

Referring to Figure 3, TMGI contains a variety of information, among which, the MBMS bearer service identifier is 24bits, and the number of bits of the above-mentioned MBMS user service identifier can be set within the range of 24bits as required. If it is set to 21bits, then the following 3bits are bearer identifiers . When the first 21 bits of multiple MBMS bearer service identifiers are the same, it indicates that the multiple MBMS bearer services correspond to the same MBMS user service.

When one MBMS bearer service serves different MBMS user services, the MBMS user service identifier in the MBMS bearer service identifier is used to indicate an MBMS user service group, representing all MBMS user services on the MBMS bearer service.

Method 2: A new field is added in the MBMS session start request message as the MBMS user service identifier, which is used to identify the MBMS user service corresponding to the MBMS bearer service requested to be established. The MBMS user service identifier is a unique identifier defined by the BM-SC, and its length range can be determined according to actual conditions. For example, referring to FIG. 4, the length is set to 24 bits.

202: After receiving the MBMS session start request message, the CN returns an MBMS session start response message to the BM-SC, and sends the MBMS session start request message to the RAN.

203: After receiving the MBMS session start request message, the RAN returns an MBMS session start response message to the CN, and according to the MBMS user service identifier contained in the MBMS session start request message, allocates a wireless air interface for the MBMS bearer service established by the above request resources to establish a radio bearer.

In this embodiment, when the wireless access network has only one carrier supporting the MBMS service, the MBMS user service corresponding to the MBMS bearer service requested to be established is determined according to the identifier of the MBMS user service, and the MBMS bearer service requested to be established is determined according to the MBMS user service Create a radio bearer.

When the radio access network has multiple carriers supporting MBMS services, the RAN establishes the MBMS bearer service corresponding to the same MBMS user service on the same carrier. If the user service has established an MBMS bearer service on the first carrier, the MBMS bearer service currently requested to be established is also established on the first carrier, thereby avoiding the allocation of different carriers for different MBMS bearer services corresponding to the same MBMS user service , correspondingly, the requirements on the terminal are reduced, and the terminal is not required to have the capability of multiple receivers. Here, two MBMS bearer services correspond to one MBMS user service as an example. When multiple MBMS bearer services correspond to the same MBMS user service, the radio access network allocates same carrier. For example, if there are three MBMS bearer services corresponding to the same MBMS user service, the radio access network allocates the same carrier for the three MBMS bearer services for transmission.

204: Judging whether the establishment of the radio bearer is successful, if successful, the RAN transmits the MBMS user service corresponding to the MBMS bearer service to the terminal UE through the established radio bearer; if it fails, determines the corresponding MBMS user service according to the identification of the above MBMS user service user service, and stop using other established MBMS bearer services of the MBMS user service to transmit the MBMS user service to the terminal.

For example, one MBMS user service corresponds to five MBMS bearer services. Two MBMS bearer services have been established and are being used to transmit the MBMS user service. The other three MBMS bearer services have not been established yet. Resources are tight. When establishing the third MBMS bearer service, if the wireless bearer fails to be established, the radio access network stops using the established two MBMS bearer services to continue transmitting the MBMS user service, thereby avoiding the waste of wireless air interface resources.

In this embodiment, the entity that specifically performs resource allocation is a radio access controller in the RAN, such as an RNC, or a NodeB, or an eNodeB.

The above method provided by the embodiment of the present invention enables the wireless access network to allocate the same carrier for all MBMS bearer services corresponding to the same MBMS user service according to the MBMS user service identifier, so that the requirements for the terminal are reduced during multi-carrier transmission. It avoids bad influence on the quality of MBMS user service during multi-carrier transmission. When establishing a radio bearer for the MBMS bearer service requested to be established fails, determine other established MBMS bearer services corresponding to the same MBMS user service as the MBMS bearer service requested to be established, and stop using the established MBMS bearer service to transmit MBMS User services are provided to the terminal, which avoids incomplete transmission of MBMS user services and waste of wireless air interface resources when wireless air interface resources are in short supply.

Example 3

Referring to Fig. 5, an embodiment of the present invention provides a method for establishing a radio bearer for a multimedia broadcast/multicast bearer service, which specifically includes:

501: The BM-SC sends an MBMS session start request message to the CN, requesting to establish an MBMS bearer service, and the MBMS session start request message includes mapping information between the MBMS bearer service and the MBMS user service.

In this embodiment, the BM-SC includes the mapping information of the MBMS bearer service and the MBMS user service in the MBMS session start request message in any of the following three ways:

Method 1: The MBMS session start request message includes the identifier of the MBMS bearer service requested to be established and the identifiers of all other MBMS bearer services, and all other MBMS bearer services and the MBMS bearer service requested to be established correspond to the same MBMS user service. Specifically, the form of a list may be adopted, or TMGI may be used. The MBMS session start request message includes multiple TMGIs, and each TMGI includes an identifier of an MBMS bearer service. The MBMS bearer service identifiers in the multiple TMGIs correspond to All other MBMS bearer services should be used.

For example, the MBMS bearer service currently requested to be established is ID3, which corresponds to MBMS user service 1, and there are four other MBMS bearer services corresponding to MBMS user service 1, whose identifiers are ID1, ID2, ID4, and ID5 respectively. The request message contains 5 TMGIs in total, including TMGI3 containing ID3 of the currently requested MBMS bearer service, TMGI1 containing ID1 of other MBMS bearer services, TMGI2 containing ID2, TMGI4 containing ID4, and TMGI5 containing ID5.

Method 2: The MBMS session start request message includes the ID of the MBMS bearer service requested to be established and the ID of the MBMS bearer service to be established after the MBMS bearer service requested to be established, that is, in the form of a one-way linked list, and the latter one to be established The MBMS bearer service and the MBMS bearer service requested to be established correspond to the same MBMS user service.

In this embodiment, the form of TMGI may be used, for example, the MBMS session start request message includes the TMGI of the MBMS bearer service currently requested to be established, and the Next_TMGI of the MBMS bearer service to be established later. For example, there are 6 MBMS bearer services, the identifiers are ID1~ID6 respectively, among which, ID2, ID3 and ID6 correspond to the same MBMS user service, then when requesting to establish MBMS bearer service ID2, the Next_TMGI contained in the MBMS session start request message contains ID3 in , and contains ID6 in Next_TMGI contained in the MBMS session start request message when requesting to establish MBMS bearer service ID3.

Mode 3: The MBMS session start request message includes the identifier of an established MBMS bearer service before the MBMS bearer service requested to be established, the identifier of the MBMS bearer service requested to be established, and the MBMS bearer service to be established after the MBMS bearer service requested to be established The identifier of the MBMS bearer service is in the form of a doubly linked list, and the previously established MBMS bearer service, the MBMS bearer service requested to be established and the next MBMS bearer service to be established all correspond to the same MBMS user service.

In this embodiment, the form of TMGI may be used, and the MBMS session start request message includes Prev_TMGI, TMGI and Next_TMGI. Wherein, Prev_TMGI includes the ID of the previous established MBMS bearer service, and Next_TMGI includes the ID of the subsequent MBMS bearer service to be established. When there is no previously established MBMS bearer service, the Prev_TMG may not include the MBMS bearer service identifier, or may include ID=0. For example, there are 6 MBMS bearer services, the identifiers are ID1~ID6 respectively, wherein ID1, ID2, ID3, ID4 and ID6 correspond to the same MBMS user service, then when requesting to establish MBMS bearer service ID3, the MBMS session start request message The Prev_TMGI contained in contains ID2, and the Next_TMGI contains ID4.

502: After receiving the MBMS session start request message, the CN returns an MBMS session start response message to the BM-SC, and sends the MBMS session start request message to the RAN.

503: After receiving the MBMS session start request message, the RAN returns an MBMS session start response message to the CN, and according to the mapping relationship between the MBMS bearer service and the MBMS user service contained in the MBMS session start request message, establishes the MBMS The bearer service allocates wireless air interface resources and establishes a wireless bearer.

In this embodiment, when the radio access network has only one carrier serving the MBMS service, the RAN determines the MBMS user service corresponding to the MBMS bearer service requested to be established according to the mapping relationship between the MBMS bearer service and the MBMS user service, and according to the MBMS user service The service allocates wireless air interface resources for the MBMS bearer service requested to be established, and establishes the bearer.

When the radio access network has multiple carriers supporting the MBMS service, as described in step 203 in Embodiment 2, the RAN establishes the MBMS bearer service corresponding to the same MBMS user service on the same carrier.

504: Judging whether the established radio bearer is successful, if successful, the RAN transmits the MBMS user service corresponding to the above MBMS bearer service to the terminal UE through the established radio bearer; if it fails, according to the mapping information of the above MBMS user service, determine the The MBMS user service corresponding to the MBMS bearer service requested to be established stops transmitting the MBMS user service to the terminal using other established MBMS bearer services of the MBMS user service.

In this embodiment, the entity that specifically performs resource allocation is a radio access controller in the RAN, such as an RNC, or a NodeB, or an eNodeB.

The above method provided by the embodiment of the present invention enables the radio access network to allocate the same carrier for all MBMS bearer services corresponding to the same MBMS user service according to the mapping information of the MBMS bearer service and the MBMS user service, so that the multi-carrier transmission reduces the It fulfills the requirement on the terminal and avoids bad influence on the quality of MBMS user service during multi-carrier transmission. When establishing a radio bearer for the MBMS bearer service requested to be established fails, determine other established MBMS bearer services corresponding to the same MBMS user service as the MBMS bearer service requested to be established, and stop using the established MBMS bearer service to transmit MBMS User services are provided to the terminal, which avoids incomplete transmission of MBMS user services and waste of wireless air interface resources when wireless air interface resources are in short supply.
