Description

Service data transmission method and device
Technical Field

Background
With the rapid development of the scale of the mobile internet, more and more users watch high-definition video, online video on demand and other types of services through a terminal (a mobile phone, a tablet computer and the like) and a mobile network, so that the network has an increasing demand for bearing capacity. On the other hand, in some typical scenarios, there is a need for a large number of terminals to request the same service at the same time. In the existing mobile communication network, when a plurality of terminal devices request the same service data in sequence, a base station device needs to allocate independent transmission resources for each terminal device and send the service data to each terminal device, i.e. in a unicast manner, so that a large amount of repeated sending of the same service data is caused, and the system bandwidth is wasted.
To solve the bottleneck problem of air interface high speed services, especially video services, enhanced multimedia broadcast multicast service (eMBMS) is proposed in version R9 of 3GPP (3rd generation partnership project). By adopting the single-point-to-multipoint broadcasting technology, the service data is transmitted from one data source to a plurality of terminals, the network resources can be effectively utilized, and the total flow of the network data is reduced, so that the utilization rate of the network resources is improved, and the transmission load and the occupation of air interface resources are saved. However, when the base station broadcasts the service data, the terminal access broadcast occurs randomly, and the terminal receives the service data broadcasted by the base station after the access broadcast time, that is, if the terminal does not access the broadcast when the service data starts to be broadcast, but accesses the broadcast after the broadcast starts, the terminal misses the service data broadcasted by the base station in a period from the broadcast start time to the self access broadcast time, so that the experience of a user who does not access the broadcast in time by the terminal is reduced when the base station broadcasts the service data.

With the rapid development of the scale of the mobile internet, more and more users watch high-definition video, online video on demand and other types of services through a terminal (a mobile phone, a tablet computer and the like) and a mobile network, so that the network has an increasing demand for bearing capacity. On the other hand, in some typical scenarios, there is a need for a large number of terminals to request the same service at the same time. In the existing mobile communication network, when a plurality of terminal devices request the same service data in sequence, a base station device needs to allocate independent transmission resources for each terminal device and send the service data to each terminal device, i.e. in a unicast manner, so that a large amount of repeated sending of the same service data is caused, and the system bandwidth is wasted.
To solve the bottleneck problem of air interface high speed services, especially video services, enhanced multimedia broadcast multicast service (eMBMS) is proposed in version R9 of 3GPP (3rd generation partnership project). By adopting the single-point-to-multipoint broadcasting technology, data are transmitted from one data source to a plurality of terminals, network resources can be effectively utilized, and the total flow of network data is reduced, so that the utilization rate of the network resources is improved, and the transmission load and the occupation of air interface resources are saved. However, when the base station broadcasts the service data, the terminal accesses the broadcast to receive the service data broadcasted by the base station at the moment, that is, if the terminal does not access the broadcast when the service data starts to be broadcasted, but accesses the broadcast after the start time, the service data broadcasted by the base station in the period from the broadcast start time to the self-access broadcast will be missed, so that the experience of the user who does not access the broadcast in time by the terminal will be reduced when the base station broadcasts the service data.
In order to solve the above problems, the basic principle of the present application is: after the macro base station receives the service request of the terminal and determines that the target broadcast data stream of the target service data in the service request exists, the macro base station broadcasts the broadcast data stream requested by the terminal to the terminal at the current moment, and for the target service data transmitted between the transmission starting moment of the target broadcast data stream missed by the terminal and the current moment, the macro base station sends an assistance transmission request to the micro base station to indicate the micro base station to send the service data missed by the terminal to the terminal, so that the terminal can completely receive the service data whenever accessing the broadcast, and the user experience is improved.
The embodiment of the present application may be applied to a system formed by a terminal, a macro base station, and a micro base station, as shown in fig. 1, where a range covered by the macro base station 11 includes the micro base station 12, a range covered by the micro base station 12 includes the terminal 13, and the terminal 13 may communicate with both the macro base station 11 and the micro base station 12, and may also communicate with both the macro base station 11 and the micro base station 12.
It is understood that before implementing the solution provided in the present 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 configured to broadcast a broadcast data stream carrying service data to the terminal 13. In the present application, the macro base station 11 may further send an assistance 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 micro base station 12 is configured to send service data missed in the broadcast data stream by the terminal 13 to the terminal 13 in a unicast manner according to the instruction of the macro base station 11; the terminal 13 is configured to receive service data sent by the macro base station 11 or the micro base station 12.
In addition, the embodiment of the present application further provides a device for transmitting service data, which is applied to the macro base station 11, the micro base station 12, or the terminal 13, and is used to implement a method for transmitting service data, where the device for transmitting service data may also be the macro base station 11, 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, which is shown in fig. 2 and includes the following steps:
201. and the terminal sends a service request to the macro base station, wherein the service request carries the identifier of the target service data.
First, in the embodiment of the present application, a macro base station, a micro base station, and a terminal need to establish a communication connection in advance. It can be understood that, in the process of the macro base station broadcasting, there is more than one terminal, and therefore, when the terminal sends a service request to the macro base station, the service request needs to carry not only the identifier of the target service but also the identifier of the terminal, so as to uniquely identify the terminal.
202. And the macro base station receives the service request sent by the terminal.
203. The macro base station determines a target broadcast data stream in which target service data currently exists.
The selection method of the target broadcast data stream may be: and determining the broadcast data stream with the shortest time length between the transmission starting time and the current time in at least one broadcast data stream of the target service data as the target broadcast data stream.
Generally, the macro base station only transmits the service data of the hot spot service in a broadcast manner, so that the macro base station may determine that the target service is the hot spot service according to the identifier of the target service data before step 203. Of course, the present application is not limited to the hotspot service, and other service data with broadcast requirements may also be applicable. In addition, usually, there are multiple broadcast data streams of one service data on a macro base station at one time, and each broadcast data stream may be initiated at different times, and when a terminal accesses the broadcast data stream of the service data at the current time, in order to receive as much service data as possible in the broadcast data stream, the macro base station will generally access the terminal to the broadcast data stream that is newly initiated by the service data, therefore, step 203 specifically includes determining at least one broadcast data stream of the target service data; and determining the broadcast data stream with the shortest time length between the transmission starting time and the current time in at least one broadcast data stream of the target service as the target broadcast data stream.
For example, the broadcast data stream of the a service data broadcasted by the macro base station is specifically divided into a broadcast data stream of the a service data broadcasted at 10 points and a broadcast data stream of the a service data broadcasted at 10 points, the terminal requests the macro base station for the a service data, and the macro base station determines that the a service data is the target service data. The macro base station determines that two broadcast data streams of the A service data currently exist, and the broadcast data stream of the A service data which is broadcasted by 10 points 10 separately is obtained through calculation and is the latest broadcast data stream, and then the macro base station determines the broadcast data stream of the A service data which is broadcasted by 10 points 10 separately as the target broadcast data stream.
Since there may be multiple broadcast data streams of the target service data in the macro base station for the target service data requested by the terminal, the macro base station needs to calculate the transmission start time t of each broadcast data stream broadcast1And the current time t2And selecting the broadcast data stream with the minimum difference delta t as the target broadcast data stream. Therefore, more target service data can be transmitted to the terminal in a macro base station broadcasting mode, and the bandwidth is saved.
204. And the macro base station sends the target broadcast data stream after the current moment to the terminal.
Specifically, the macro base station broadcasts the target service data to the terminal in a manner that first, the target service data is requested from a service source, and then, the target service data is generated into a target broadcast data stream and is broadcast and sent to the terminal.
205. And the terminal receives the target broadcast data stream after the current moment, which is sent when the macro base station determines that the target broadcast data stream of the target service data exists at present.
206. And the macro base station sends an assistance transmission request to the micro base station, wherein the assistance transmission request is used for indicating the micro base station to send target service data transmitted from the transmission starting moment of the target broadcast data stream to the current moment in the target broadcast data stream to the terminal.
And the assistant transmission request is sent by the macro base station to the micro base station and used for indicating the micro base station to request the target service data transmitted from the transmission starting moment of the target broadcast data stream to the current moment in the target broadcast data stream from the service source. Wherein, the request for assisting transmission comprises the following information: the identification of the terminal, the identification of the target service data and the data volume; the terminal mark is used for uniquely identifying the terminal and indicating a transmission object of the micro base station; the identification of the target service data is used for uniquely identifying the service data requested by the terminal, and the micro base station requests the target service data from the service source by using the identification of the target service data; the data volume is used for indicating the byte size of target service data transmitted from the transmission starting time of the target broadcast data stream to the current time, the macro base station of the data volume can be obtained by calculating the target service data which is already broadcasted in the target service data stream, and the micro base station requests the target service data with the data volume size from the service source by using the data volume.
It is to be understood that, because the time for the macro base station to send the assistance transmission request to the micro base station is short, the step for the macro base station to send the assistance transmission request to the micro base station may occur simultaneously with step 204 in terms of timing, may also occur before step 204, or may occur after step 204, which is exemplified in the embodiment of the present application as occurring after step 204.
207. And the micro base station receives an assistance transmission request sent by the macro base station.
208. And the micro base station responds to the assistance transmission request to acquire target service data transmitted from the transmission starting time of the target broadcast data stream to the current time in the target broadcast data stream.
Specifically, the way for the micro base station to obtain 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 transmission assisting request is that 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.
When the micro base station requests a service source for target service data transmitted from the transmission starting time of the target broadcast data stream to the current time in the target broadcast data stream, the micro base station comprises the following information: identification and data volume of target service data; the micro base station requests the target service data from a service source by using the identifier of the target service data; the data volume is used for indicating the byte size of target service data transmitted from the transmission starting time of the target broadcast data stream to the current time, the macro base station of the data volume can be obtained by calculating the target service data which is already broadcasted in the target service data stream, and the micro base station requests the target service data with the data volume size from the service source by using the data volume.
Since the service data in the service source are arranged in sequence, in the embodiment of the present application, the micro base station requests the service source for the target service data transmitted between the transmission start time of the target broadcast data stream and the current time, that is, the service data arranged in sequence from the start position to the specified number of bytes in the service source. It can be understood that there are other ways to implement that the micro base station requests 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 are not described herein again.
209. And the micro base station sends the target service data transmitted from the transmission starting time of the target broadcast data stream to the current time in the target broadcast data stream to the terminal.
Generally, the sequence 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 starting time of the target broadcast data stream to the current time is in front of the target broadcast data stream broadcast by the macro base station, and the target broadcast data stream broadcast by the macro base station is behind 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 and the current time to the terminal in a unicast manner, and of course, if the amount of service data missed by the terminal is large, the large amount of unicast data of the micro base station may waste too many resources, so a time threshold t may be set0For example, prior to step 204, the macro base station may first determine a transmission start time t for the target broadcast data stream1To the current time t2The time length between is less than or equal to the preset time threshold t0At this time, step 204 is executed, otherwise, if the transmission start time t of the target broadcast data stream is determined1To the current time t2The time length between is greater than a preset time threshold t0And the macro base station generates a new broadcast data stream of the target service data and sends the new broadcast data stream to the terminal.
Specifically, the macro base station transmits a target broadcast data stream at a start time t1To the current time t2Time duration preset time threshold t between0At the time of calculating and selecting the transmission start time t1To the current time t2After the target broadcast data stream with the smallest difference Δ t, the difference Δ t is less than or equal to the time threshold t0The macro base station indicates the micro base station to perform reissue, if the difference value delta t is greater than the time threshold t0The macro base station re-initiates the broadcast data stream.
In this way, the macro base station determines whether to reissue the part of the content or re-initiate a new broadcast data stream according to the size of the content missing from the terminal, and when the missing content is less, the macro base station is instructed to reissue the content; and when the content is missing more, the macro base station initiates a new broadcast data stream again. The mode can effectively prevent the micro base from being used when the terminal has more missing contents or even all the missing contentsIn the case of stations transmitting large amounts of data, i.e. the time threshold t0The data volume of macro base station broadcasting and micro base station reissuing can be balanced, and the utilization rate of bandwidth is improved.
In the embodiments of the present application, after the terminal accesses the broadcast, the macro base station broadcasts the broadcast data stream requested by the terminal to the terminal according to the existing broadcast technology, and if the terminal is the broadcast accessed after the broadcast start time, for the service data missed by the terminal within a period from the broadcast start time to the terminal access broadcast, the macro base station sends the transmission assistance request to the micro base station to instruct the micro base station to send the service data missed by the terminal to the terminal, so that the terminal can completely receive the service data whenever accessing the broadcast, and user experience is improved.
The following describes the embodiments of the present application in detail with reference to several specific examples: first, taking an example that the macro base station sends the service data of the hot spot service in a broadcast manner, as shown in fig. 3, the present application further provides a service data transmission method, which details a case that the macro base station determines that the target service is not the hot spot service according to the identifier of the target service data.
301. And the terminal sends a service request to the macro base station, wherein the service request carries the identifier of the target service data.
302. And the macro base station determines that the type of the target service data is not the hot spot service according to the identification of the target service data.
The types of the target service data are divided into hot spot services and non-hot spot services.
303. The macro base station requests target service data from the service source.
For example, the macro base station may send a request carrying an identifier of the target service to the service source to request the target service data.
304. And the service source sends target service data to the macro base station.
305. And the macro base station unicasts the target service data to the terminal.
The specific implementation manner of the description in 301-305 may refer to the corresponding description in step 201-209, and is not described herein again.
For more convenient understanding of the above embodiments, as shown in fig. 4 below, the present application further provides a method for transmitting service data, where a macro base station determines that target service data is a hot spot service according to an identifier of the target service data, but a broadcast data stream of the hot spot service does not exist in the macro base station.
401. And the terminal sends a service request to the macro base station, wherein the service request carries the identifier of the target service data.
402. And the macro base station determines the target service data as the hot spot service according to the identification of the target service data.
403. And the macro base station determines that the broadcast data stream of the hot spot service does not exist currently.
404. The macro base station re-initiates a new broadcast data stream.
405. And the macro base station sends the number of the target broadcast data stream to the terminal.
Since there may be multiple broadcast data streams of the target service in the macro base station, the embodiments of the present application distinguish the multiple broadcast data streams of the target service data using numbers. It is to be understood that the numbering is merely a specific way of distinguishing, and that other ways may be distinguished, which are not limited by the embodiments of the present application.
406. The terminal sends confirmation information to the macro base station.
407. And the macro base station determines that the terminal accesses the target broadcast data stream.
408. The macro base station requests target service data from the service source.
409. And the service source sends target service data to the macro base station.
410. And the macro base station sends the target broadcast data stream after the current moment to the terminal.
It can be understood that, since the macro base station re-initiates a new broadcast data stream, for the terminal, the target broadcast data stream broadcasted by the macro base station at the current time is complete service data of the target service data, that is, the terminal can completely receive the target service data, so that it is no longer necessary for the macro base station to instruct the micro base station to re-send the target service data that the terminal has not received.
The specific implementation manner of the description in 401-.
As shown in fig. 5, the present application further provides a method for transmitting service data, in which a macro base station determines that a target service requested by a terminal is a hot spot service, but a transmission start time t of a target broadcast data stream1And the current time t2Is greater than a time threshold t0The case (1).
501. And the terminal sends a service request to the macro base station, wherein the service request carries the identifier of the target service data.
502. And the macro base station determines the target service data as the hot spot service according to the identification of the target service data.
503. The macro base station determines that at least one broadcast data stream of the target service data currently exists.
504. And the macro base station determines that the target broadcast data stream of the target service data does not exist currently.
