Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

In order to solve the problem that the backhaul bandwidth between the gateway device and the base station cannot meet the transmission requirement, and at the same time, the network transformation cost is not increased, the backhaul bandwidth resource of each base station connected with the gateway device is utilized in the application to solve the problem. In each base station connected with the gateway device, not all base stations are in a full load state all the time, so that the data transmission requirement between the base stations and the gateway device can be met by sharing the backhaul bandwidth between the base stations.

The data transmission method provided by the application can be applied to an application environment shown in figure 1. Wherein, the plurality of base stations 100 are in communication connection with the gateway device 200, the gateway device 200 is in communication connection with the core network 300, and the standard supported by the base stations 100 comprises: long term evolution (Long Term Evolution, LTE) standard, wideband multiple access (Wideband Code Division Multiple Access, WCDMA) standard, global system for mobile communications (Global System for Mobile, GSM) standard, worldwide interoperability for microwave access (World Interoperability for Microwave Access, wiMax) standard, and others. The plurality of base stations may be base stations of the same system or base stations of different systems. The base station may be a distributed base station, a densely-networked base station, or the like, and is not limited herein.

In one embodiment, as shown in fig. 2, a data transmission method is provided, and the method is applied to the base station in fig. 1 for illustration, and includes the following steps:

s101, detecting whether a backhaul bandwidth between a first base station and gateway equipment meets a preset transmission requirement.

The gateway device provides a convergence and routing forwarding function for a plurality of base stations and a core network, and can send uplink data of the plurality of base stations such as a first base station and a second base station connected to the gateway device to the core network, and also can send received downlink data to corresponding base stations respectively. The first base station and the gateway device may be connected through an optical fiber, or may be connected through a network cable, which is not limited herein.

The backhaul bandwidth is used to characterize the size of data that can be transmitted between the first base station and the gateway device, and the backhaul bandwidth may be a bandwidth allocated to the first base station by the gateway device, or may be a bandwidth determined by hardware conditions of the first base station and the gateway device, which is not limited herein.

When the first base station sends uplink data to the gateway device, the first base station can detect whether the backhaul bandwidth meets a preset transmission requirement. The preset transmission requirement may be that the transmission rate is greater than a preset threshold, or that the data flow is greater than a preset threshold, which is not limited herein. Specifically, the first base station can determine whether the current transmission rate is greater than a preset threshold value through a detection instruction periodically output by the base station; or, the first base station may receive the data state monitoring information sent by the gateway device, determine whether the current backhaul bandwidth meets the transmission requirement, and the detection mode is not limited herein.

Optionally, the first base station may monitor data traffic between the first base station and the gateway device; if the data traffic is greater than the preset trigger sharing threshold, determining that the backhaul bandwidth between the first base station and the gateway device does not meet the preset transmission requirement.

Specifically, the first base station may configure a trigger sharing threshold, which may be determined based on a backhaul bandwidth between the first base station and the gateway device. For example, when the backhaul bandwidth between the first base station and the gateway device is 10M, the first base station may configure the trigger sharing threshold to be 10Mbps; in addition, the first base station may also consider that the data transmission is stable, and the trigger sharing threshold is set to 8Mbps, which is not limited herein. When the data traffic is greater than a preset trigger sharing threshold, the backhaul bandwidth cannot meet the transmission requirement.

Specifically, the first base station may detect whether the backhaul bandwidth between the first base station and the gateway device meets a preset transmission requirement in real time, or may detect when the received uplink data is greater than a certain number, or may detect according to a preset period, which is not limited herein.

S102, if the uplink split data does not meet the requirement, the first base station sends the uplink split data to gateway equipment through the second base station; the gateway equipment is used for sending the uplink shunt data to the core network; the second base station is a base station which can provide shared resources and is allocated to the first base station by the gateway equipment.

Under the condition that the first base station determines that the backhaul bandwidth does not meet the transmission requirement, the gateway device can allocate shared resources for the first base station, and allocate a second base station capable of providing the shared resources to the first base station, so that the first base station can send uplink split stream data to the gateway device through the second base station.

Specifically, the second base station allocated by the gateway device to the first base station may be one base station, or may include a plurality of base stations, which is not limited herein.

The split data may be all uplink data that the first base station needs to send to the gateway device, or may be part of the uplink data that the first base station needs to send to the gateway device, which is not limited herein. When the first base station selects part of data in the uplink data to be sent to the second base station as uplink split data, the first base station can determine which of the uplink data are uplink split data according to the size of shared resources which can be provided by the second base station; or, the first base station may send the data with the preset size to the second base station as uplink split data under the condition that the backhaul bandwidth does not meet the transmission requirement. For example, the uplink data to be sent to the gateway device by the first base station is 100Mbps, the backhaul bandwidth between the first base station and the gateway device is 10Mbps, in one scenario, the second base station may provide a shared resource of 100Mbps, and the first base station may send uplink data of 90Mbps to the second base station as uplink split data; in another scenario, the first base station may send the preset size data as uplink split data to one of the second base stations, for example, 20Mbps, and if detecting that the backhaul bandwidth still cannot meet the preset transmission requirement, send other data to the other second base station allocated by the gateway device.

After receiving the uplink split data sent by the second base station, the gateway device may send the uplink split data to the core network.

After receiving the downlink data sent by the core network to the first base station, the gateway device can determine whether the backhaul bandwidth between the gateway device and the first base station meets the transmission requirement of the downlink data. If the backhaul bandwidth does not meet the requirement, the gateway device may determine a third base station capable of providing shared resources, and send downlink data of the first base station to the first base station through the third base station; the third base station may be a second base station in uplink transmission, or may be another base station connected to the gateway device. In addition, the gateway device may also determine whether the first base station transmits the uplink data through the second base station, and then select a corresponding channel to transmit the downlink data. The first base station can receive downlink split data forwarded by the second base station; the downlink split data is data which is sent to the second base station after the gateway equipment receives the downlink data sent by the core network.

According to the data transmission method, the first base station detects whether the backhaul bandwidth between the first base station and the gateway equipment meets the preset transmission requirement; if not, the first base station sends the uplink shunt data to the gateway equipment through the second base station; the gateway equipment is used for sending the uplink shunt data to the core network; the second base station is a base station which can provide shared resources and is allocated to the first base station by the gateway equipment. The first base station detects whether the backhaul bandwidth between the first base station and the gateway equipment meets the preset transmission requirement, so that the first base station can send uplink shunt data to the gateway equipment through the second base station in the existing network according to the second base station which can provide shared resources and is allocated by the gateway equipment under the condition that the backhaul bandwidth does not meet the preset transmission requirement, and the transmission rate of the uplink data of the first base station is ensured; furthermore, the method does not need to reform the network, thereby saving the cost of network reformation and improving the utilization rate of network resources.

Fig. 3 is a flow chart of a data transmission method in another embodiment, where the embodiment relates to a manner in which a first base station sends uplink split data to a gateway device through a second base station, and on the basis of the foregoing embodiment, as shown in fig. 3, the foregoing method further includes:

s201, the first base station sends a sharing request message to the gateway equipment.

Specifically, after determining that the backhaul bandwidth does not meet the transmission requirement, the first base station may send sharing request information to the gateway device to notify the gateway device of allocation of the shared resource thereto.

The sharing request message may include an identifier or code of the first base station, and may include a sharing interface address of the first base station, where the sharing interface address is used to transmit split data between the base stations; in addition, the size of the resource required by the first base station may also be included, and the specific content of the sharing request message is not limited herein.

S202, a first base station acquires a sharing request response returned by gateway equipment; the sharing request response includes a sharing interface address of the second base station, which is determined by the gateway device according to the sharing request message and a sharing information list, where the sharing information list is used to characterize sharable resources of each base station connected to the gateway device.

After receiving the sharing request message, the gateway device selects a second base station capable of providing sharable resources for the first base station according to the sharing request message and the sharing information list, and then sends the sharing interface address of the second base station to the first base station through a sharing request response. The sharing request response may further include a base station identifier of the second base station, or a number of the second base station, which is not limited herein.

The shared information list may include a shared interface address of each base station and a corresponding sharing factor, where the sharing factor represents a size of a sharable resource that may be provided by the base station; and may also include an identification of the base station, etc.

Specifically, after receiving the sharing request response, the gateway device may query the sharing information list for which base stations can provide the shared resources currently, and the gateway device may determine the base station with the largest sharing factor as the second base station, or may select an appropriate sharing factor according to the size of the resource required by the first base station included in the sharing request response, and then determine the base station corresponding to the sharing factor as the second base station; the determination method of the second base station is not limited herein.

After receiving the sharing request response, the first base station can send the uplink split data to the second base station through the sharing interface address of the second base station, so that the second base station sends the uplink split data to the gateway device. The first base station may send the uplink split data to the second base station through wired connection, or may send the uplink split data to the second base station through wireless connection, which is not limited herein.

According to the data transmission method, the first base station sends the sharing request information to the gateway equipment, so that the gateway equipment can allocate the proper second base station to the first base station according to the sharing request information and the sharing information list, and therefore the first base station can directly send the uplink split data to the second base station according to the sharing interface address of the second base station, the uplink split data of the first base station is more stable to transmit, the transmission rate of the uplink split data of the first base station is guaranteed, and the utilization efficiency of resources in a system is improved.

In one embodiment, based on the above embodiment, the first base station sends the sharing parameter of the first base station to the gateway device; the sharing parameter of the first base station comprises a sharing interface address of the first base station and a sharing factor of the first base station, and the sharing parameter is used for indicating the gateway device to update the sharing information list based on the sharing parameter of the first base station.

Specifically, the first base station may determine the size of the resource that may be shared according to the throughput size in the application and the backhaul bandwidth of the first base station and the gateway device so far. For example, if the throughput is larger in the application, the first base station may provide fewer shared resources, and the set sharing factor is smaller; if the throughput is smaller in the application, the first base station can provide more shared resources, and the set sharing factor is larger.

Optionally, the sharing parameter of the first base station may further include a sharing function switching parameter. For example, when the first base station can provide the shared resource, the value of the switch parameter of the shared function is set to be on, and when the first base station no longer provides the shared resource, the value of the switch parameter of the shared function is set to be off.

Specifically, the first base station may send the shared parameter to the gateway device when registering the network, or may send the shared parameter to the gateway device when the value of the parameter in the shared parameter changes, which is not limited herein. For example, the first base station may report the sharing parameter to the gateway device through the sharing information notification message when registering the network; or, when the sharing factor or the sharing interface address is changed, the first base station may report the updated sharing parameter to the gateway device through the sharing information change notification request. For example, after the first base station sends the sharing request message to the gateway device, the first base station cannot provide sharable resources, and may report the sharing factor of 0 to the gateway device.

Similar to the first base station, other base stations accessing the gateway device may also send respective sharing parameters to the gateway device, including the sharing interface address of each base station and the sharing factor of each base station. After receiving each sharing parameter, the gateway device can learn which base stations can provide sharing resources, and save or update the sharing parameters in a sharing information list.

In addition, when maintaining the sharing factor request list, the gateway device may also automatically update the sharing information list according to the sharing request sent by each base station. For example, after receiving the sharing request message sent by the first base station, the gateway device may automatically set the sharing factor corresponding to the first base station in the sharing information list to 0, or mark that sharing of the second base station is unavailable.

According to the data transmission method, the first base station sends the sharing parameters of the first base station to the gateway equipment, so that the gateway equipment can know whether the first base station can provide the sharing resources or not, and timely update the sharing information list, so that the gateway equipment can dynamically allocate the sharing resources for the base station needing the sharing resources, and the resource utilization efficiency of the system is improved. When the second base station provides the shared resource for the first base station and encounters a data burst, the gateway device can also allocate the base station capable of providing the shared resource for the second base station so as to share the transmission load of the second base station, thereby ensuring the stability of data transmission.

In an embodiment, on the basis of the foregoing embodiment, after the first base station receives the sharing shutdown instruction, the sending of the uplink split data to the second base station is stopped; the share shutdown instruction is sent by the gateway device or the second base station.

In one scenario, the shared function closure procedure may be initiated by the second base station. And when any one of the following conditions occurs in the second base station, a sharing function closing flow can be initiated, and a sharing closing instruction is sent to the first base station: the first case is that the second base station stops the sharing function, e.g. the sharing function switch is turned off; the second condition is that the second base station is abnormal, so that uplink shunt data sent by the first base station cannot be continuously received; the third situation is that the uplink data burst of the second base station itself or the uplink data of the second base station is greater than the sharing trigger threshold of the second base station, so that no more sharing resources can be provided. If the second base station is abnormal and initiates the sharing function closing flow, the second base station may send a request for notifying the gateway device of the change of the sharing information, notifying the gateway device to set the sharing factor of the second base station in the sharing information list to 0, or mark that the sharing of the second base station is unavailable.

In another scenario, since the gateway device may obtain more base station status information, when the gateway device detects that the second base station is unregistered, or is not online, the gateway device may automatically set the sharing factor of the second base station to 0 or mark that the second base station sharing is not available to prevent the second base station from being allocated to other base stations again. Further, the gateway device may issue a share shutdown instruction to the first base station, where the share shutdown instruction may be an offline notification of the second base station, or a message that the gateway device de-registers with the second base station.

And after the first base station receives the sharing closing instruction, stopping sending the uplink shunt data to the second base station. And under the condition that the first base station detects that the backhaul bandwidth still does not meet the transmission requirement, the first base station can continuously send a sharing request message to the gateway equipment so as to acquire the new base station allocated by the gateway equipment.

According to the data transmission method, after the first base station receives the sharing closing instruction, the first base station stops sending the uplink split data to the second base station, so that the situation that the second base station cannot normally receive the uplink split data or cannot send the received uplink split data to the gateway equipment is avoided, and the reliability of data transmission is improved.

In one embodiment, as shown in fig. 4, a data transmission method is provided, and the method is applied to the gateway device in fig. 1 for illustration, and includes the following steps:

s301, the gateway equipment receives uplink split stream data sent by a second base station; the uplink split data is sent to the second base station by the first base station under the condition that the first base station detects that the backhaul bandwidth between the first base station and the gateway equipment does not meet the preset transmission requirement; the second base station is a base station which can provide shared resources and is allocated to the first base station by the gateway equipment.

Specifically, each base station may determine the size of the resources that may be shared according to the throughput size in the application and the backhaul bandwidth with the gateway device so far. For example, if the throughput is larger in the application, the base station can provide fewer shared resources, and the set sharing factor is smaller; if the throughput is smaller in the application, the base station can provide more shared resources, and the set sharing factor is larger. Optionally, the sharing parameter may further include a sharing function switching parameter.

S502, the gateway equipment updates the shared information list based on each shared parameter.

After receiving each sharing parameter, the gateway device can learn which base stations can provide sharing resources, and save or update the sharing parameters in a sharing information list. In addition, when maintaining the sharing factor request list, the gateway device may also automatically update the sharing information list according to the sharing request sent by each base station. For example, after receiving the sharing request message sent by the first base station, the gateway device may automatically set the sharing factor corresponding to the first base station in the sharing information list to 0, or set the sharing function switch parameter of the first base station to be turned off.

According to the data transmission method, the gateway equipment receives the sharing parameters sent by each base station connected with the gateway equipment, so that the gateway equipment can dynamically allocate the sharing resources for the base stations needing the sharing resources, and the resource utilization efficiency of the system is improved.

Fig. 7 is a schematic flow chart of a data transmission method in an embodiment, which relates to a process of sending downlink data by a gateway device, and on the basis of the above embodiment, as shown in fig. 7, the method further includes:

s601, the gateway equipment receives downlink data of a first base station sent by a core network.

After the gateway device receives the data sent by the core network, it can determine, according to the destination sending address of the data, which data are downlink data that need to be sent to the first base station. The target sending address may be an address of the terminal device, and the gateway device may determine, according to a correspondence between the terminal device and the accessed base station, to which base station the data should be sent, so as to obtain downlink data of the first base station.

S602, the gateway equipment sends downlink split data of downlink data to the second base station, and sends other data in the downlink data to the first base station; the downlink split data corresponds to the uplink split data and is forwarded to the first base station through the second base station.

After receiving the downlink data, the gateway device may first determine whether the downlink data includes downlink split data corresponding to the uplink split data. Specifically, the gateway device may determine whether the downlink data is downlink split data according to a transmission path of uplink data corresponding to the downlink data; if the uplink data corresponding to the downlink data is uplink split data, which is sent to the gateway device by the first base station through the second base station, that is, the uplink data corresponding to the downlink data is uplink split data, the gateway device may determine that the downlink data is downlink split data. If the uplink data corresponding to the downlink data is sent directly to the gateway device by the first base station, the gateway device may determine that the downlink data is not downlink split data.

Alternatively, the gateway device may determine the transmission path of the uplink data through the information reception list. For example, after the gateway device receives the uplink data, the terminal identifier corresponding to the uplink data and the base station identifier corresponding to the uplink data may be recorded in the information receiving list, so as to determine what path the uplink data corresponding to the terminal identifier is sent to the gateway device. In one implementation, the information receiving list may be part of a shared information list.

The gateway device may search the information receiving list for the uplink data corresponding to the terminal identifier according to the terminal identifier corresponding to the downlink data, and determine the transmission path of the uplink data through which base station is transmitted to the gateway device. If the transmission path of the uplink data corresponding to the terminal identifier is transmitted to the gateway device through the second base station, the gateway device may determine the downlink data as downlink split data. If the transmission path of the uplink data corresponding to the terminal identifier is transmitted to the gateway device through the first base station, the gateway device may not use the downlink data as downlink split data.

Further, the gateway device sends the downlink split data of the downlink data to the second base station, and sends other data except the downlink split data in the downlink data to the first base station. After the second base station receives the downlink split data sent by the gateway device, the second base station can send the downlink split data to the first base station through the shared interface address of the first base station indicated by the gateway device.

In one scenario, when the same terminal device sends uplink data to the first base station and the second base station at the same time, in order to avoid the problem of routing confusion of the gateway device, the gateway device is caused to make an uncertainty about to which base station the downlink data of the terminal device is returned, and the second base station can modify the source address of the received downlink split data into the address of the second base station, so that the gateway device can accurately determine the uplink data sending path of the terminal device.

According to the data transmission method, the gateway equipment sends the downlink data to the second base station according to the condition that the base station identifier associated with the terminal equipment corresponding to the downlink data is the identifier of the second base station, so that the uplink data and the downlink data of the same terminal equipment are sent through the same transmission channel, the scheduling flow among the base stations is simplified, the base station distribution efficiency is improved, and the downlink data sending time delay is reduced.

In one embodiment, as shown in fig. 8, a data transmission method is provided, and the method is applied to the base station in fig. 1 for illustration, and includes the following steps:

s701, a second base station receives uplink split data sent by a first base station; the uplink split data is sent to the second base station by the first base station under the condition that the first base station detects that the backhaul bandwidth between the first base station and the gateway equipment does not meet the preset transmission requirement; the second base station is a base station which is distributed by gateway equipment for the first base station and can provide shared resources;

S702, the second base station sends uplink split stream data to gateway equipment; the gateway device is used for sending the uplink shunt data to the core network.

In an embodiment, on the basis of the foregoing embodiment, the foregoing method further includes: the second base station receives downlink split data sent by the gateway equipment, wherein the downlink split data is data sent to the second base station after the gateway equipment receives the downlink data sent by the core network; and the second base station sends the downlink split data to the first base station through the shared interface address of the first base station indicated by the gateway equipment.
