As shown in FIG. 1, FIG. 1 is a schematic diagram of a wireless network architecture supporting eMBMS. In Figure 1, the system architecture supporting the eMBMS in the 3GPP (3rd Generation Partnership Project) includes the following network elements and devices: User Equipment (UE), which supports activation/deactivation of eMBMS bearer services. Features. An evolved UMTS (Universal Mobile Telecommunications System) (Evolved UMTS Terrestrial Radio Access Network) for implementing functions related to the wireless evolved network, and transmitting eMBMS data to designated eMBMS service area. The mobility management entity 104 (MME, Mobility Management Entity) is responsible for mobility management of the control plane, such as user context and mobility state management, and allocation of user temporary identity. A packet data network gateway 105 (PDN GW, Packet Data Network Gateway), as a landing point for IP (Internet Protocol) multicast transmission, is a user plane anchor between a 3GPP access network and a non-3GPP access network. Interface of the external packet data network (PDN, Packet Data Network). eMBMS GW 106 (eMBMS Gateway, eMBMS Gateway), providing eMBMS GW106 and BM-SC 107 (Broadcast Multicast service center) The control plane SGmb interface, and the user plane SGi-mb interface between the eMBMS GW 106 and the BM-SC 107, and the GTPU (GPRS Tunneling Protocol User Plane, GPRS Tunneling Protocol User Plane) of the SGi-mb interface eMBMS session service data Encapsulation, and multicast distribution to the eNB (evolved Node B, evolved base station) on the M1 interface, and providing functions such as multicast destination IP address allocation. The BM-SC 107 is used to save subscription data, generate billing records, member management (Gi interface), determine a schedule for eMBMS session transmission, determine a schedule for retransmission of eMBMS sessions, identify each eMBMS session, and host each eMBMS session. Temporary Mobile Group Identity (TM) (Temporary Mobile Group Identity); GGSN (Gateway GPRS Support Node GPRS, GPRS Gateway Support Node) provides transmission-related parameters such as QoS (Quality of Service), eMBMS Service area, etc.; initiate or terminate eMBMS bearer resources; send eMBMS data and have the function of error bounce policy. The SGSN 108 (Serving GPRS Support Node) is connected to the eMBMS GW 106 through the Sn interface, and is connected to the UTRAN 103 (UMTS Terrestrial Radio Access Network) through the lu interface. The content provider 109 (content provider) is a server that provides eMBMS services.

At present, operators use the eMBMS method to send service data streams to user equipment in real time. For example, for live broadcasts of sports events, operators can use eMBMS to send video of programs to group users, so that group users can receive live matches. video. Alternatively, the third-party application can notify the operator to provide service to the group user for the specific content through the eMBMS method. For example, the sports live broadcast service, the content provider of the live sports broadcast transmits data on the established eMBMS bearer service, and when the user needs to receive data, the eMBMS service group can be added, so that the live broadcast can be watched.

The advantage of using the eMBMS bearer service to transmit data is that the same data can be transmitted to multiple user equipments in the same eMBMS service area and at the same time period, thereby saving network resources. Currently, it is basically only used for the transmission of real-time services.

In some scenarios, the user equipment does not require real-time performance for certain data services. For example, for some applications of the update software, the user may not care about the transmission time of the update file, then such data for such user equipment Business, if the operator adopts a single for each user based on the user granularity The transmission of data streams in the broadcast mode will result in wasted resources. Therefore, how to adopt eMBMS for such services has no solution for simultaneously transmitting data files for such user equipment.

In the service data transmission phase, the first network device transmits the service data to the user equipment by using the eMBMS bearer service after determining to use the eMBMS bearer service to transmit the service data to the user equipment.

It should be noted that, in the embodiment of the present invention, the service data refers to the data information that the user equipment requests to receive, and is the service data requested by the service request message. For example, if the user equipment requests the APP to upgrade the service, the service data is the data required for the APP upgrade. For another example, if the user requests a downloaded file (such as a multimedia file), then the multimedia file is also the user's business data. Different types of business data, such as data required for APP upgrades, and files requested by users (such as multimedia files) can be distinguished by service identification.

The specific implementation process of the preparation phase in the embodiment of the present invention is described below.

FIG. 6 is a schematic diagram of a service subscription process according to an embodiment of the present invention. In FIG. 6, the user equipment can be divided into an underlying layer and an application layer, and the application layer refers to an application installed on the user equipment, such as an APP. The bottom layer is the part of the user equipment other than the application layer. In the embodiment of the present invention, a logical layer "intermediate layer" is introduced in the user equipment. In the embodiment of the present invention, the “middle layer” can also be deployed in combination with the existing bottom layer and application layer.

Based on the above description, the preparation phase of establishing an eMBMS bearer service may include the following steps:

Optionally, step 0: the application layer registers with the middle layer

The user equipment may register the application that is not received in real time on the middle layer, or may register the application on the middle layer when the application is installed, and the registered content includes one or more of the following information: service identifier, application version information, and the like.

Step 1: Get information about the application layer

If there is step 0, the intermediate layer can directly obtain information of the application layer registered in the middle layer, for example, service identifier, application version information, service attribute information, and the like. If there is no step 0, the middle layer can also obtain the information of the application layer from the bottom layer.

On the other hand, the user equipment can register data file information that is not received in real time to the middle layer or Application media information, such as video files that users can receive in real time.

Step 2: The application layer sends a service request message.

The service request message sent by the middle layer of the user equipment to the first network device, the service attribute information and the user equipment identifier included in the service request message, and the specific content in the service request message will be described in detail in the following embodiments. , will not repeat them here.

It should be noted that, in the embodiment of the present invention, the eMBMS bearer service refers to a broadcast mode, and simultaneously transmits the same service data to user equipments in the same eMBMS service area.

With reference to FIG. 2, FIG. 3, FIG. 4 and FIG. 5, as shown in FIG. 7, the embodiment of the present invention further provides a flowchart of an eMBMS implementation method, which belongs to the transmission data phase. The execution body of FIG. 7 may be a service platform, may be a capability open functional unit, or may be a device including a service platform and a capability open functional unit.

As shown in FIG. 7, the method includes:

Step 701: The first network device receives a service request message sent by the user equipment, where the service request message includes service attribute information and a user equipment identifier of the user equipment.

Step 702: The first network device determines, according to the service attribute information and the user equipment identifier, that the service data is transmitted to the user equipment by using an eMBMS bearer service.

Step 703: The first network device uses the eMBMS bearer service to transmit service data to the user equipment.

In step 701, the user equipment identifier in the service request message received by the first network device refers to the identifier information used to distinguish the user equipment. The specific expression is not limited. For example, it may be an IMSI (International Mobile Subscriber Identity, International Mobile). Subscriber Identity), IMEI (International Mobile Equipment Identity), MSISDN (Mobile Station International ISDN Number), or other application layer used to identify user equipment identification information, such as external identification ( External Identifier). It can also be IP address information and the like.

The service request message received by the first network device may further include at least one of the following information:

Establishing eMBMS bearer service indication information, where the establishing eMBMS bearer service indication information is used And indicating to send the service data requested by the user equipment by using the eMBMS bearer service.

The first network device may determine, according to the setup eMBMS bearer service indication information sent by the user equipment, that the service requested by the user equipment can transmit the service data by using the eMBMS bearer service.

Optionally, when the service request message does not include the service data time information, the user equipment may be configured to receive the requested application data at any time. Therefore, the service request time information may not be sent in the service request message. Of course, the received service data time information may also indicate that the user equipment can receive the requested application data at any time.

The first network device may determine a time range in which the user equipment can receive data according to the received service data time information sent by the user equipment. The first network device can transmit the service data to the user equipment user equipment within the time range.

The service attribute information received by the first network device further includes at least one of the following parameters:

Version information of the application;

Apply media information.

It should be noted that the service represented by the service identifier requested by the user equipment may also be a multimedia video or audio service.

The information indicating the received service data included in the service request message, or the indication information of the service data may be received by the eMBMS bearer service, where the first network device determines that the user who can receive the service data at the same time is greater than the threshold, and at the user equipment The user equipment that requests the service data with the same service attribute is greater than the threshold, and the first network device determines that the user equipment that requests the same service attribute service data sends the service data by using the eMBMS bearer service mode, and determines the time for sending the service data. .

It should be noted:

The threshold value may be determined according to actual conditions, and the embodiment of the present invention is not limited herein.

The number of the user equipment is determined according to the acquired user equipment identifier.

It should be noted that the service attribute information received by the first network device may include multiple service identifiers.

For example, when determining that there are N applications that need to receive service data through the eMBMS bearer service, the user equipment sends the service identifier corresponding to the application that needs to receive data through the eMBMS bearer service through the same service attribute information, thereby reducing the number of letters. Let the cost, N be a positive integer.

For example, after determining that an application needs to receive data through the eMBMS bearer service, the user equipment does not immediately send a service request message, but waits for a preset time length, and if there are multiple applications in the preset time length, The service data needs to be received by the eMBMS bearer service, and the service attribute information in the service request message sent by the user equipment will include the service identifier of all applications that need to receive data through the eMBMS bearer service.

Optionally, after receiving the service request message sent by the user equipment, the first network device first authenticates the user equipment identifier in the service request message and the service attribute information in the service request message, and determines the user equipment and the requested Whether the application is authorized to request to establish an eMBMS bearer service. If the authentication fails, the service request message of the user equipment is rejected, and the message is returned to the user equipment, indicating that the authentication fails; if the authentication is successful, the service request message is further processed. analysis.

In step 702, the first network device may determine, according to the received service data time information in the received service request message, the time when the user equipment can receive the service data; or the first network device determines that the received service request message does not include the receiving. When the service data time information, it can be determined that the user equipment can receive the service data at any time. At the same time, the first network device may determine the service data requested by the user equipment according to the service identifier in the service request message. When the first network device determines that the number of user equipments requesting to receive the same service data at the same time is greater than a threshold, it is determined to transmit the service data to the user equipment using the eMBMS bearer service. The number of user equipments may be determined according to the number of user equipment identifiers. The threshold value may be determined according to the actual situation, and the embodiment of the present invention is not limited herein.

The same time refers to the time intersection of the time point or time period when the user equipment requesting to receive the same service data can receive the service data. Due to the point in time at which different user equipment can receive business data or The time period may be different. In order to determine whether to use the eMBMS bearer service to transmit service data, after receiving the service request sent by the user equipment that requests the same service, the first network device needs to count different time points or time segments. The number of user equipments that receive service data, and then determines whether to use the eMBMS bearer service to transmit service data according to the statistical result. Specifically, the first network device determines a time point or a time period that each user equipment receives the service data, and then determines a plurality of time intersections according to a time point or a time period that each user equipment receives the service data; and determines each time intersection. The number of corresponding user equipments is determined to be used to transmit service data using the eMBMS bearer service if the number of user equipments corresponding to one of the time intersections is greater than a threshold.

For example, the six user equipments are A, B, C, D, E, and F, and the requested service data is the same. The time at which A can receive service data is 12 points; the time at which B can receive service data is 12 to 13 points; the time at which C can receive service data is 12:30 to 13: D can receive services. The time point of the data is 12:30 to 14: the time point at which E can receive the business data is 12:40 to 14: the time at which F can receive the business data is 14; the threshold is 4. Then at 12 o'clock only A and B can receive business data; from 12:30 to 12:40, there are B, C, D, E can receive business data; at 14 o'clock there are B, C, D, E, F can Receive business data and more. Finally, the first network device determines that, at the same time, at 14 o'clock, the number of corresponding user equipments is 5, which is greater than the threshold 4, and it is determined that the eMBMS bearer service is used to transmit the service data.

For example, the user equipment requests an application upgrade service from the first network device. Since the application upgrade service is not an operation that needs to be performed immediately, the user equipment can perform the application upgrade service at any time. At this time, the user equipment may indicate, by using the received service data time information in the service request message, the time when the user equipment can receive the service data, or the user equipment may not send the received service data time information in the service request message, thereby indicating that the user equipment may be in the Receive business data at any time. The first network device may receive an application upgrade service sent by the multiple user equipments to the same application, and the first network device collects the service request message statistics, in the generally accepted time of receiving the data file, if If the number of users requesting to receive the same service data is greater than the threshold, it is determined that the service data is transmitted to the user equipment by using the eMBMS bearer service.

After determining that the eMBMS bearer service is used to transmit the service data to the user equipment, the first network device starts to initiate a process of establishing an eMBMS bearer service.

It should be noted that the specific process for the first network device to initiate the establishment of the eMBMS bearer service may be as follows:

Step 2: The first network device receives the TMGI allocation response message returned by the BM-SC, where the TMGI allocation response message includes the TMGI allocated by the BM-SC for the eMBMS bearer service established by the user equipment.

Step 3: The first network device sends an eMBMS service parameter message for indicating a service parameter of the eMBMS bearer service to the user equipment, where the eMBMS service parameter message includes a parameter such as a TMGI allocated by the BM-SC.

At the same time, the first network device also sends the eMBMS service parameters to other network elements, for example, the GGSN and the SGSN that have been registered to the corresponding eMBMS bearer service, and all the BSCs (Base Station Controllers) connected to the registered SGSNs. RNC (Radio network controller).

After the eMBMS bearer service is established, the first network device sends, to the second network device, an eMBMS service indication message, which is used to indicate that the second network device performs service transmission, where the eMBMS service indication message includes a service identifier, an identifier of the user equipment, and the like. .

Optionally, in the process of establishing an eMBMS bearer service, the eMBMS service parameter message further includes one or any combination of the following parameters:

Before the first network device transmits the service data to the user equipment, it may also receive the service data requested by the user equipment transmitted by the second network device. The first network device caches the service data requested by the second network device and requested by the user equipment. Or the first network device notifies the second network device to cache the data. If the first network device determines to use the eMBMS bearer service to transmit service data to the user equipment, after the eMBMS bearer service is established, the already cached service data is transmitted using the eMBMS bearer service.

Finally, in step 703, if the first network device sends the service data to the user in the manner of using the eMBMS bearer service, determining one or more eMBMS service areas according to the location information sent by the user equipment, and serving the eMBMS service areas to the eMBMS service area. The user equipment transmits the service data using the eMBMS bearer service.
