Background technique

With the rapid development of the mobile Internet scale, more and more users watch high-definition video, online video on demand and other types of services through terminals (mobile phones, tablet computers, etc.) and mobile networks, which makes the network more and more demanding for carrying capacity . On the other hand, in some typical scenarios, there are a large number of terminals requesting the same service at the same time. In the existing mobile communication network, when multiple terminal devices successively request the same service data, the base station device needs to allocate independent transmission resources to each terminal device and send service data to each terminal device respectively, that is, unicast This results in a large number of repeated transmissions of the same service data, which wastes the system bandwidth. Therefore, the current communication network often has a bottleneck in this case.

In order to solve the bottleneck problem of air interface high-speed services, especially video services, in the R9 version of 3GPP (3rd generation partnership project, 3rd generation partnership project), an enhanced multimedia broadcast multicast service (eMBMS) was proposed. ). By adopting point-to-multipoint broadcasting technology to transmit service data from one data source to multiple terminals, network resources can be effectively utilized and the total network data flow can be reduced, thereby improving network resource utilization and saving transmission load and air interface resource occupation. However, when the base station broadcasts service data, the terminal access broadcast occurs randomly. After the terminal accesses the broadcast, it receives the service data broadcast by the base station after the access broadcast time. That is to say, if the terminal does not start broadcasting the service data, it will Access to the broadcast, but the broadcast that is accessed after the broadcast starts, will miss the service data broadcast by the base station during the period from the start of the broadcast to the time when it accesses the broadcast. Therefore, when the base station broadcasts the service data, the terminal will not The experience of users who access the broadcast in time is degraded.

With the rapid development of the mobile Internet scale, more and more users watch high-definition video, online video on demand and other types of services through terminals (mobile phones, tablet computers, etc.) and mobile networks, which makes the network more and more demanding for carrying capacity . On the other hand, in some typical scenarios, there are a large number of terminals requesting the same service at the same time. In the existing mobile communication network, when multiple terminal devices successively request the same service data, the base station device needs to allocate independent transmission resources to each terminal device and send service data to each terminal device respectively, that is, unicast This results in a large number of repeated transmissions of the same service data, which wastes the system bandwidth. Therefore, the current communication network often has a bottleneck in this case.

In order to solve the bottleneck problem of air interface high-speed services, especially video services, in the R9 version of 3GPP (3rd generation partnership project, 3rd generation partnership project), an enhanced multimedia broadcast multicast service (eMBMS) was proposed. ). By adopting point-to-multipoint broadcasting technology, data is transmitted from one data source to multiple terminals, which can effectively utilize network resources and reduce the total network data traffic, thereby improving network resource utilization, saving transmission load and air interface resource occupation. However, when the base station broadcasts service data, the terminal accesses the broadcast and receives the service data broadcast by the base station at the moment, that is, if the terminal does not access the broadcast when the service data starts to be broadcast, but accesses it after the start time If the broadcast is used, the service data broadcast by the base station during the period from the start of the broadcast to the time when the base station accesses the broadcast will be missed. Therefore, when the base station broadcasts the service data, the experience of the user whose terminal does not access the broadcast in time will be degraded.

In order to solve the above problems, the basic principle of the present application is: after the macro base station receives the service request from the terminal and determines that there is a target broadcast data stream of the target service data in the service request, the macro base station will start broadcasting the terminal request to the terminal at the current moment. For the target service data transmitted between the transmission start time and the current time of the target broadcast data stream missed by the terminal, the macro base station sends an assisted transmission request to the micro base station, instructing the micro base station to send the service data missed by the terminal. To the terminal, therefore, whenever the terminal accesses the broadcast, it can completely receive the service data and improve the user experience.

The embodiments of the present application can be applied to a system composed of a terminal, a macro base station, and a micro base station. As shown in FIG. 1 , the macro base station 11 covers the micro base station 12 , and the micro base station 12 covers the terminal 13 . 13 can communicate with both the macro base station 11 and the micro base station 12, and can also communicate with the macro base station 11 and the micro base station 12 at the same time.

It can be understood that, before implementing the solution provided in this application, the terminal 13 first establishes a communication connection with the micro base station 12 and the macro base station 11 . In the solution of the present application, the macro base station 11 is used to broadcast a broadcast data stream carrying service data to the terminal 13 . In this application, the macro base station 11 may also send an assisted transmission request to the micro base station 12 to instruct the micro base station 12 to send the service data missed by the terminal 13 in the broadcast data stream to the terminal 13; The instruction sends the service data missed by the terminal 13 in the broadcast data stream to the terminal 13 in a unicast manner; the terminal 13 is used to receive the service data sent by the macro base station 11 or the micro base station 12 .

In addition, the embodiments of the present application also provide a service data transmission apparatus applied to the macro base station 11 or the micro base station 12 or the terminal 13. The service data transmission apparatus is used to implement the service data transmission method, and the service data transmission apparatus also It may be the macro base station 11 or the micro base station 12 or the terminal 13 itself or a chip therein.

Based on the above system, an embodiment of the present application provides a method for transmitting service data. Referring to FIG. 2 , the method includes the following steps:

201. The terminal sends a service request to the macro base station, where the service request carries an identifier of target service data.

First, in the embodiment of the present application, the macro base station, the micro base station and the terminal need to establish a communication connection in advance. It can be understood that there is more than one terminal during the broadcast of the macro base station. Therefore, when the terminal sends a service request to the macro base station, the service request not only needs to carry the identifier of the target service, but also needs to carry the identifier of the terminal to uniquely identify the terminal. .

202. The macro base station receives the service request sent by the terminal.

203. The macro base station determines that a target broadcast data stream of the target service data currently exists.

The selection method of the target broadcast data stream may be: determining the broadcast data stream with the shortest duration between the transmission start time and the current time in at least one broadcast data stream of the target service data as the target broadcast data stream.

Usually, since the macro base station only transmits the service data of the hotspot service in a broadcast manner, before step 203 , the macro base station may also determine that the target service is a hotspot service according to the identifier of the target service data. Of course, the present application is not limited to hot-spot services, and other service data with broadcasting requirements can also be applied. In addition, there are usually multiple broadcast data streams of one service data on the macro base station at one moment, and each broadcast data stream may be initiated at different times. When the terminal accesses the broadcast data stream of the service data at the current moment, in order to Receive as much service data as possible in the broadcast data stream, and usually the macro base station will access the terminal to the latest broadcast data stream initiated by the service data. Therefore, step 203 specifically includes determining at least one broadcast data stream of the target service data; A broadcast data stream with the shortest duration between the transmission start time and the current time among at least one broadcast data stream of the target service is determined as the target broadcast data stream.

For example, the broadcast data stream of the A service data broadcast by the macro base station is specifically divided into the broadcast data stream of the A service data broadcast at 10:00, and the broadcast data stream of the A service data broadcast at 10:10. The terminal requests the macro base station for A Service data, the macro base station determines the A service data as the target service data. The macro base station determines that there are currently two broadcast data streams of A service data. After calculation, it is determined that the broadcast data stream of the A service data broadcasted at 10:10 is the latest broadcast data stream, then the macro base station will start broadcasting at 10:10. The broadcast data stream of the A service data is determined as the target broadcast data stream.

For the target service data requested by the terminal, there may be multiple broadcast data streams of the target service data in the macro base station. Therefore, the macro base station needs to calculate the transmission start time t ₁ and the current time t ₂ of each broadcast data stream broadcast. The difference Δt is selected, and the broadcast data stream with the smallest difference Δt is selected as the target broadcast data stream. In this way, more target service data can be transmitted to the terminal in the form of macro base station broadcast, saving bandwidth.

204. The macro base station sends the target broadcast data stream after the current time to the terminal.

Specifically, the macro base station broadcasts the target service data to the terminal by first requesting the target service data from the service source, and then generating the target broadcast data stream from the target service data, which is broadcast and sent to the terminal.

205. The terminal receives the target broadcast data stream after the current moment sent when the macro base station determines that the target broadcast data stream of the target service data currently exists.

206. The macro base station sends an assisted transmission request to the micro base station, where the assisted transmission request is used to instruct the micro base station to send the target service data transmitted from the transmission start time of the target broadcast data stream to the current time in the target broadcast data stream to the terminal.

The assisted transmission request sent by the macro base station to the micro base station is used to instruct the micro base station to request the service source for the target service data transmitted from the transmission start time of the target broadcast data stream to the current time in the target broadcast data stream. Among them, the assisted transmission request includes the following information: the identification of the terminal, the identification of the target service data, and the amount of data; the identification of the terminal is used to uniquely identify the terminal and indicates the transmission object of the micro base station; the identification of the target service data is used to uniquely identify the terminal request. The micro base station requests the target service data from the service source with the identifier of the target service data; the data volume is used to indicate the byte size of the target service data transmitted from the transmission start time of the target broadcast data stream to the current time, The data volume of the macro base station can be calculated by the target service data that has been broadcast in the target service data stream, and the micro base station uses the data volume to request the target service data of the size of the data volume from the service source.

It can be understood that, because the time for the macro base station to send the assisted transmission request to the micro base station is relatively short, the step of sending the assisted transmission request from the macro base station to the micro base station may occur at the same time as step 204 in time sequence, or may also occur in step 204. Before, or after step 204 , in this embodiment of the present application, it is exemplified that it occurs after step 204 .

207. The micro base station receives the assisted transmission request sent by the macro base station.

208. The micro base station acquires, in response to the transmission assistance request, the target service data transmitted from the transmission start time of the target broadcast data stream to the current time in the target broadcast data stream.

Specifically, the micro base station obtains the target service data transmitted from the transmission start time of the target broadcast data stream to the current time in the target broadcast data stream in response to the request for assistance in transmission. First, the micro base station requests the target service data from the service source. , and then the service source sends the target service data requested by the micro base station to the micro base station.

Wherein, when the micro base station requests the target broadcast data stream from the target broadcast data stream for the target service data transmitted from the transmission start time of the target broadcast data stream to the current moment, the following information is included: the identifier of the target service data and the data volume; wherein, The identifier of the target service data is used to uniquely identify the service data requested by the terminal, and the micro base station requests the target service data from the service source with the identifier of the target service data; the data volume is used to indicate the time from the transmission start time of the target broadcast data stream to the current time. The size in bytes of the target service data to be transmitted between the macro base stations can be calculated by the target service data broadcasted in the target service data stream.

Since the service data in the service source is arranged in order, in the embodiment of the present application, what the micro base station requests from the service source is the target service data transmitted between the transmission start time of the target broadcast data stream and the current time, that is, The business data from the starting position to the specified number of bytes in order in the business source. It can be understood that there are many other ways for the micro base station to request the service source for the target service data transmitted from the transmission start time of the target broadcast data stream to the current time in the target broadcast data stream, which will not be repeated here. .

209. The micro base station sends, to the terminal, the target service data in the target broadcast data stream that is transmitted from the transmission start time of the target broadcast data stream to the current time.

Usually, the order of the target service data played by the terminal is: in the target broadcast data stream unicast by the micro base station, the target service data transmitted from the transmission start time of the target broadcast data stream to the current time is first, and the target service data broadcast by the macro base station is first. The broadcast data stream is behind, therefore, according to the actual situation of the terminal, an optional operation is to locally cache the target broadcast data stream broadcast by the macro base station.

In step 209, the micro base station may send the target service data transmitted between the transmission start time of the target broadcast data stream to the current time to the terminal in a unicast manner. Of course, if the amount of service data missed by the terminal is large, the micro base station will The large amount of data unicast by the base station will waste too many resources, so a time threshold t ₀ can be set. For example, before step 204, the macro base station can first determine the transmission start time t ₁ of the target broadcast data stream to the current time t ₂ The duration between is less than or equal to the preset time threshold t ₀ , then step 204 is executed, otherwise, if it is determined that the duration between the transmission start time t ₁ of the target broadcast data stream to the current time t ₂ is greater than the preset time With the threshold t ₀ , the macro base station generates a new broadcast data stream of the target service data, and sends it to the terminal.

Specifically, the macro base station presets a time threshold t ₀ for the duration between the transmission start time t ₁ and the current time t ₂ of the target broadcast data stream, and calculates and selects the difference between the transmission start time t ₁ and the current time t ₂ After the target broadcast data stream with the smallest value Δt, if the difference Δt is less than or equal to the time threshold t ₀ , the macro base station instructs the micro base station to re-send, and if the difference Δt is greater than the time threshold t ₀ , the macro base station re-initiates the broadcast data stream.

In this way, the macro base station decides whether to reissue this part of the content or re-initiate a new broadcast data stream according to the size of the content missing from the terminal. When there is less missing content, the micro base station is instructed to reissue; broadcast data stream. This method can effectively prevent the micro base station from re-sending a large amount of data when the terminal has a lot of missing content or even all the content. That is, the time threshold t ₀ can balance the amount of data broadcast by the macro base station and the data re-issued by the micro base station and increase the bandwidth. usage rate.

In the above embodiments of the present application, after the terminal accesses the broadcast, the macro base station will broadcast the broadcast data stream requested by the terminal to the terminal according to the existing broadcast technology. For the missed service data from the broadcast start time to the time when the terminal accesses the broadcast, the macro base station sends an assisted transmission request to the micro base station, instructing the micro base station to send the service data missed by the terminal to the terminal. Therefore, whenever the terminal is Access to the broadcast can completely receive service data and improve user experience.

The solution of the present application will be described in detail below with reference to several specific examples: first, take the example that the macro base station transmits the service data of the hotspot service in a broadcast manner, as shown in FIG. 3 , the present application also provides a method for transmitting service data, The case where the macro base station determines that the target service is not a hotspot service according to the identifier of the target service data is introduced in detail.
