Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example one

The embodiment of the invention provides a link data processing method. Fig. 1 is a schematic flowchart of a link data processing method according to a first embodiment of the present invention; as shown in fig. 1, the method includes:

step 101: and obtaining the reference signal strength of the terminal.

Step 102: and selecting at least two links to be connected with the terminal based on the reference signal strength and the historical link selection record.

Step 103: and carrying out data distribution processing according to the selected link quantity and the link condition corresponding to the link.

The link selection method described in this embodiment may be applied to a network device, where the network device may specifically be a base station, and further, the network device may specifically be an anchor base station, or may be referred to as a master base station. Historical link selection records are recorded and stored in the network equipment, and the historical link selection records comprise link selection information of the terminal under various network environments and actual geographic environments. As an embodiment, the historical link selection record includes a terminal identifier, a selected link identifier, and real-time information of the terminal, where the real-time information of the terminal may specifically be a reference signal strength of the terminal. Based on the above, when the link to be connected is selected for the terminal, at least two links matching with the reference signal strength are selected from the historical link selection records based on the current reference signal strength of the terminal, and the at least two links can be used as a link set.

In an embodiment, the method further comprises: obtaining at least one of position information of a terminal, service type of the terminal, base station load information and base station interference information; correspondingly, selecting at least two links to be connected with the terminal based on the reference signal strength and the historical link selection record comprises: selecting at least two links to be connected with the terminal based on the reference signal strength, the at least one information and a historical link selection record.

Wherein the selecting at least two links connected with the terminal based on the reference signal strength, the at least one information and a historical link selection record comprises: searching the historical link selection record based on the reference signal strength or the reference signal strength and the position information to obtain a matched link set; the link set comprises at least two links; and selecting at least two links connected with the terminal from the link set based on at least one of the service type of the terminal, the load information of the base station and the interference information of the base station.

In this embodiment, the real-time information of the terminal included in the historical link selection record may further include location information of the terminal. Wherein the location information of the terminal may be represented by at least one of: latitude and longitude information, information of a communication cell where the terminal is located, information of a base station to which the terminal is connected, and the like. In practical application, the serving base station connected to the terminal may obtain information representing the location of the terminal, such as information of a communication cell where the terminal is located, information of a base station connected to the terminal, or latitude and longitude information of the terminal, from a communication signaling with the terminal. The reference signal strength may be obtained by base station measurements. When the network device is not the serving base station, the network device may communicate with the serving base station to obtain the reference signal strength and the location information of the terminal. The location information of the terminal stored in the history link selection record is consistent with the obtained location information type of the terminal, so as to facilitate the subsequent matching process. In another embodiment, the area range represented by the type of the position information of the terminal stored in the historical link selection record is larger than the area range represented by the type of the obtained position information of the terminal; for example, the type of the location information of the terminal stored in the history link selection record may be an area range corresponding to the communication cell (the area range may be identified by a latitude and longitude range), and the obtained location information of the terminal may be latitude and longitude information. Based on the link selection record, the network equipment searches the historical link selection record based on the obtained position information of the terminal, and obtains a link set which is matched with the position information of the terminal and contains at least two pieces of link information.

In addition, in the process of matching the reference signal strength, as long as the obtained reference signal strength is compared with the historical reference signal strength recorded in the historical link selection record, and the difference value is within the range of the preset floating threshold value, the reference signal strength and the historical reference signal strength can be determined to be matched and consistent.

In this embodiment, the terminal service type is a current service type of the terminal obtained in real time; the base station load and/or interference information is a current load condition and/or interference condition of a service base station connected with the terminal and is characterized by being obtained in real time. And the network equipment selects at least two links connected with the terminal from the link set based on at least one of the current service type of the terminal, the base station load information and the base station interference information. The service type of the terminal may represent the requirements for the time-delay and reliability of the link on one hand, and may also represent the required resources on the other hand; for example, when the service type of the terminal is a video call service, the service has high requirements for latency and reliability, and requires relatively large resources. The base station load condition represents the number of links to be connected supported by the current base station, for example, the current load of the base station is higher, and the number of correspondingly supported links to be connected is relatively smaller; when the current load of the base station is low, the number of correspondingly supported links to be connected may be relatively large. The base station load condition may also indicate the amount of data transmitted by the link to be connected, for example, the current load of the base station is too high, and the amount of data supported and transmitted by the corresponding link to be connected is relatively small; when the current load of the base station is low, the amount of data supported and transmitted by the corresponding link to be connected may be relatively large. Base station interference information can affect data transmission quality, and several increased interferences can lead to increased error rates.

Based on this, the network device selects at least two links satisfying at least one of the terminal service type, the base station load information and the base station interference condition from the selected link set including at least two links, and satisfies the requirements of the time delay performance and the reliability of the current service of the terminal under the current load and/or interference condition of the base station. And further carrying out data distribution processing according to the selected link quantity and the link condition corresponding to the link.

By adopting the technical scheme of the embodiment of the invention, at least two links matched with the reference signal strength of the terminal are selected from the historical link selection records, so that on one hand, the full utilization of wireless resources is ensured, on the other hand, the reliability requirement of data transmission is met, and the time delay is reduced.

Example two

The embodiment of the invention also provides a link data processing method. Fig. 2 is a schematic flowchart of a link data processing method according to a second embodiment of the present invention; as shown in fig. 2, the method includes:

step 201: the method comprises the steps of obtaining the reference signal strength of a terminal, and obtaining at least one of position information, terminal service types, base station load information and base station interference information of the terminal.

Step 202: selecting at least two links to be connected with the terminal based on the reference signal strength, the at least one information and a historical link selection record.

Step 203: and respectively obtaining the transmission quality, the transmission capability and the link load information of the at least two links.

Step 204: and proportionally distributing data to be transmitted according to at least one of the information of the transmission quality, the transmission capacity and the link load information of the at least two links to the at least two links, and transmitting the data through the at least two links according to the proportion distribution result.

In this embodiment, a person skilled in the art can understand the above steps 201 to 202 by referring to the first embodiment, and details are not described here for brevity.

In this embodiment, when the number of the selected links is 2, that is, when two links to be connected to the terminal are selected, the data to be transmitted is divided into the two links in proportion, so that the two links transmit different data. Wherein, the dividing the data to be transmitted to the two links according to the proportion comprises: and determining the data distribution proportion of the two links according to at least one of the transmission quality, the transmission capacity and the link load information of each of the two links. As an embodiment, the data transmission delay of each link can be estimated according to the transmission quality, transmission capability and link load information of each link, and the data splitting ratio of each link is determined based on the data transmission delay. For example, if the data transmission delay of one link is longer than that of the other link, the data splitting ratio of the link should be smaller than that of the other link, so that the terminal can receive all data at the fastest speed. As another embodiment, the data splitting ratio may also be determined according to the transmission quality, transmission capability, and link load information of each link in combination with the service type of the terminal.

In this case, the terminal can only combine the data packets collected from the two links into the total data before splitting. However, the transmission quality, transmission capability, and the like of the two links are likely to be different, and there is a possibility that multiple retransmissions and packet loss are required under the condition of poor link quality. Therefore, after two links are selected by using a link selection method (i.e., a method of comparing the reference signal strength with a threshold) in the prior art and data splitting is performed, some split data packets may not accurately arrive at a terminal in time, and once a data packet is lost and retransmission of a Hybrid Automatic Repeat reQuest (HARQ) and an Automatic Repeat reQuest (ARQ) fails, retransmission of a Transmission Control Protocol (TCP) is started, data that has been successfully transmitted may also be retransmitted inefficiently, which not only wastes wireless resources seriously (an anchor base station cannot split a next data packet in time) but also easily generates an iterative influence. And adopting the link selection mode of the embodiment of the invention, selecting two links based on the reference signal intensity of the terminal, at least one of the position information, the terminal service type, the base station load information and the base station interference information of the terminal and the historical link selection record, selecting a matched link set containing at least two link information from the historical link selection record, and further selecting two links meeting at least one of the terminal service type, the base station load information and the base station interference information from the link set, thereby ensuring the full utilization of wireless resources on one hand, meeting the reliability requirement of data transmission on the other hand and reducing the time delay.

In this embodiment, when the number of the selected links is greater than 2, the data to be transmitted is proportionally allocated to the two or more links according to at least one of the transmission quality, the transmission capability, and the link load information of each of the two or more links, and the data is transmitted through the two or more links based on the proportional allocation result.

As an embodiment, the allocating data to be transmitted to the at least two links according to at least one of transmission quality, transmission capacity, and link load information of the at least two links includes: determining difference information of any two links of the at least two links based on at least one of transmission quality, transmission capability and link load information of the at least two links; when the difference information of any two links in the at least two links meets a preset condition, dividing the data to be transmitted to the at least two links in proportion based on the terminal service type so as to enable the data transmitted by each link in the at least two links to be different.

Specifically, the present embodiment is mainly directed to a case where the number of links is greater than 2, that is, difference information of any two links in the two or more links is determined according to at least one of transmission quality, transmission capability, and link load information of each link in the two or more links, where the difference information may be a difference in transmission quality, a difference in transmission capability, and a difference in link load of any two links; when the difference information of any two of the more than two links meets a preset condition, that is, when the difference degree of any two of the more than two links is small, that is, when the transmission quality and/or transmission capability and/or link load conditions of each two of the more than two links are similar, dividing the data to be transmitted to the at least two links in proportion based on the terminal service type so as to enable the data transmitted by each link of the at least two links to be different. Wherein, the dividing the data to be transmitted to the two links according to the proportion based on the terminal service type comprises: and determining the data distribution proportion of the two links according to at least one of the transmission quality, the transmission capacity and the link load information of each of the two links based on the terminal service type. Specifically, the data transmission delay of each link can be estimated by using the transmission quality, transmission capability and link load information of each link, and the data distribution proportion of each link is determined based on the terminal service type and the data transmission delay.

As another embodiment, the allocating the data to be transmitted to the at least two links according to at least one of transmission quality, transmission capacity, and link load information of the at least two links in proportion comprises: determining difference information of any two links of the at least two links based on at least one of transmission quality, transmission capability and link load information of the at least two links; when the difference information of at least two links in the at least two links does not meet a preset condition, selecting a first part of links from the at least two links based on the terminal service type, and dividing data to be transmitted to the first part of links according to a proportion so as to enable the data transmitted by the first part of links to be different; and selecting a second part of link from the at least two links, so that the data transmitted by the second part of link is the same as the data transmitted by at least part of link in the first part of link; wherein the first partial link and the second partial link are combined into the at least two links.

Specifically, the present embodiment is mainly directed to a case where the number of links is greater than 2, that is, difference information of any two links in the two or more links is determined according to at least one of transmission quality, transmission capability, and link load information of each link in the two or more links, where the difference information may be a difference in transmission quality, a difference in transmission capability, and a difference in link load of any two links; when the difference information of any two of the two or more links does not meet a preset condition, that is, when the difference degree of at least two links of the two or more links is large, that is, when the difference between the transmission quality and/or transmission capability and/or link load condition of at least two links of the two or more links is large, controlling some links to transmit different contents and controlling some links to transmit the same contents based on the terminal service type, for example, selecting three links, controlling two links of the two links to divide all data to be transmitted in proportion, so that the two links transmit different contents, and controlling a third link to transmit the same data as one of the two links. The first part of links for transmitting different data are selected according to the service type of the terminal and at least one of the transmission quality, the transmission capability and the link load of the links; as an implementation manner, if the terminal service type characterization has a high requirement on latency and reliability, a link with a high transmission quality and transmission capability may be selected as the first partial link. For the second part of links transmitting the same data, the links with lower transmission quality and transmission capacity of the links can be selected to transmit the same content, so that the reliability of data transmission is ensured.

The link selection method according to the embodiment of the present invention is described below with reference to a specific application scenario.

Scene one

Fig. 3 is a schematic flowchart of an application scenario of the link selection method according to the embodiment of the present invention; the application scenario includes a primary base station and a secondary base station, and the link selection decision can be applied to the primary base station. As shown in fig. 3, the method includes:

step 301: a terminal initiates a service request, which may be a request of each service type such as a video call request; on the other hand, the terminal transmits the real-time location with the secondary base station.

Step 302: the auxiliary base station obtains the transmission quality, the transmission capacity and the link load information of the link and the reference signal strength, the position information and the service type of the terminal, sends the reference signal strength, the position information and the service type of the terminal and the transmission quality, the transmission capacity and the link load information of the link to the main base station, and the main base station selects the link and makes a shunting scheme.

Step 303 to step 304: the main base station selects a plurality of links matched with the position information and the reference signal strength from the historical link selection records based on the current position information and the reference signal strength of the terminal, and the plurality of links can be used as a link set; and then selecting N links from a plurality of links contained in the link set based on at least one of the transmission quality, the transmission capacity and the link load information of the links, formulating a distribution scheme for the data to be transmitted according to at least one of the transmission quality, the transmission capacity and the link load information of each link, and sending the distribution scheme to the auxiliary base station.

Step 305 a: when N is 2, determining the data distribution proportion of the two links according to the transmission quality, the transmission capacity and the link load information of each link in the two links, and dividing the data to be transmitted to the two links according to the proportion to enable the two links to transmit different data.

Step 305 b: when N is greater than 2 and the link difference of the two or more links is large (including the difference degree of the transmission quality, the transmission capability and the link load of the links is within the preset threshold range), determining a first part of links for transmitting data with different contents according to at least one of the transmission quality, the transmission capability and the link load information of each of the two or more links in combination with the service type of the terminal, and controlling other links except the first part of links to transmit the data with the same contents as at least part of the links in the first part of links.

Step 305 c: when N is greater than 2 and the difference between the links in the two or more links is small (including the difference degree of the transmission quality, the transmission capacity and the link load of the links is not within the preset threshold range), determining the data distribution proportion of the two links according to at least one of the transmission quality, the transmission capacity and the link load information of each link in the two or more links, and dividing the data to be transmitted to the two links according to the proportion to enable the two links to transmit different data.

For the application scenario shown in step 305b, it is particularly applicable to the scenario of ultra-high reliable low latency communication (URLLC). If the link selection scheme of the embodiment of the invention is adopted to select N links, the link transmission quality and the transmission capability of each link of the N links are analyzed, and M links with the worst link transmission quality and transmission capability are selected (M and N are positive integers, and M is less than N), so that the M links are controlled to transmit the same data, and the transmission capability of the M links is the weakest link transmission quality and transmission capability in the M links. On the basis, the remaining N-M links determine the distribution proportion according to factors such as link transmission quality, transmission capacity and link load information, so that the N-M links transmit different data contents.
