Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for processing a communication link.
Background
In a wireless communication system, communication between base stations is performed through an X2 interface or an Xn interface, and a terminal preferentially selects an X2 interface or an Xn interface between base stations to perform handover when performing mobile handover. If there is no link between the base stations, when the interface switching is performed between the base station and the core network, the switching time delay is long and the success rate is low, and the perception of the user when moving the position is poor. Therefore, the X2 interface and the Xn interface are important interfaces in 4G networks and 5G networks. The X2 interface or the Xn interface is used to establish a communication link between base stations having a neighbor relation. Specifically, the Neighbor cell is discovered manually or through (Automatic Neighbor Relation, ANR), and then whether a communication link is established through an X2 interface or an Xn interface is determined according to whether link resources of a Stream Control Transmission Protocol (SCTP) are sufficient.
The communication link is used for transmitting signaling between the base station and the terminal user and broadcast messages between the base station and the base station, for example, a certain cell configuration of the base station changes, or a state changes, and the change needs to be broadcast to an adjacent neighboring cell. Thus, if the number of the adjacent cells and the communication links are more, the probability of signaling congestion is higher, and the signaling burden of the serving cell and the adjacent cells is also larger.
However, in the prior art, as the network structure development is more and more complex, the number of cells establishing the neighboring cell relationship is already close to saturation, so that no resources can be used for newly establishing a network and neighboring cells; and some neighborhood relations and communication links which are not used any more exist; therefore, network resources and neighboring resources cannot be reasonably utilized.

Fig. 1 is a flowchart illustrating a communication link processing method according to an embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a communication link processing method, which is applied to a base station, where the base station is a device deployed in an access network to provide a wireless communication function for a User Equipment (UE). The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different Radio access technologies, names of devices having a base station function may be different, for example, in a 5G New Radio (NR) system, called a nodeb or a gNB. The name "base station" may change as communication technology evolves. For convenience of description, in the embodiment of the present invention, the apparatus for providing a wireless communication function for a UE is collectively referred to as a network side device.
The method comprises the following steps:
In a wireless communication system, each base station is covered with one or more cells, different cells may be configured to provide different bandwidths; determining activity parameters of all communication links of the base station aiming at the base station, wherein the communication links are communication links from the base station to adjacent base stations, and specifically, when wired communication is carried out, the links refer to physical lines between two nodes, such as cables or optical fibers; in radio communication, a link refers to a space of a path for propagating electromagnetic waves between two nodes, for example, between a base station and a terminal.
The first cell is any cell of the base station, the second cell is any cell of the adjacent base station, and the activity parameter is used for identifying the activity degree of a communication link of the base station and comprises the request times of transmitting a cell switching request between each cell of the base station and the cell of the adjacent base station; the handover direction of the cell handover request may be bidirectional, for example, the handover request may be a handover request for the terminal to be handed over from the first cell to the second cell, or may be a handover request for the terminal to be handed over from the second cell to the first cell.
For example, if the base station is base station a, its neighboring base stations are base stations B, there are 3 cells under base station A, B, and handover occurs between each cell, the link activity between base station a and base station B is the sum of all times of handover, as shown in table 1 below, the data shown in table 1 is the number of handover requests from the cell of base station a to the cell of base station B, and table 2 is the number of handover requests from the cell of base station B to the cell of base station a:
table 1:
table 2:
the number of handover requests transmitted between base station a and base station B is 265.
Wherein the target interface comprises an X2 interface and/or an Xn interface, and the link established by the target interface is a target communication link. An X2 interface is an interface between base stations (enbs) in a Long Term Evolution (LTE) system, and an X2 interface is used for signaling information interaction and data information interaction between two enbs. The Xn interface is an interface between 5G NR access networks (NG-RAN); in the NG-RAN, a gNB serves as an access network device to provide NR user plane and control plane protocols and functions for 5G network users, and the NG-eNB is used for providing NR user plane and control plane protocols and functions for 4G network users except for the gNB; and interfaces between the gNB and the gNB, between the gNB and the ng-eNB, and between the ng-eNB and the ng-eNB are all Xn interfaces.
If the activity parameter meets the preset link processing requirement, deleting or newly building a target communication link between the base station and the adjacent base station; in particular, the link handling requirements may include a limit on the value of the handover activity parameter; for example, if the number of times of the handover request is small, the target communication link corresponding to the handover request meets the link processing requirement for performing deletion processing on the communication link, and if the utilization rate of the target communication link is low, the target communication link is deleted, so that the situation that the newly-established network and the neighboring cell have no resources to use due to occupation of network resources and neighboring cell resources is avoided; if a target communication link established through a target interface does not exist between the base station and the adjacent base station and the switching request times transmitted by other non-target communication links are more, a new target communication link is established between the base station and the adjacent base station, so that the signaling congestion caused by the fact that signaling messages and data messages cannot be transmitted in time is avoided.
In the embodiment of the invention, the activity parameter of the communication link of the base station is determined; deleting or creating a target communication link between the base station and the adjacent base station according to the activity parameter, and deleting the target communication link with lower activity to avoid occupying network resources and adjacent cell resources so that no resources can be used in a newly created network and adjacent cells; for the cells with higher activity and without target communication link, establishing a target communication link to ensure the timely transmission of signaling messages and data messages; network resources and adjacent cell resources are reasonably scheduled through the activity parameter, and the resource utilization rate is improved; the embodiment of the invention solves the problem that network resources and adjacent cell resources cannot be reasonably utilized due to more communication links and adjacent cell relations of base station equipment in the prior art.
Optionally, in an embodiment of the present invention, the activity parameter is an activity parameter of each preset statistical period;
the method further comprises the following steps:
and in each preset counting period, counting the activity parameters of the communication link of the base station.
The activity parameter may be an activity parameter of a preset adjustment period, for example, the number of times of requests for switching requests transmitted by each communication link is counted in the current preset adjustment period, and the counted number is used as the activity parameter of the next preset adjustment period.
Optionally, in this embodiment of the present invention, if the activity parameter meets a preset link processing requirement, the step of performing deletion processing or new creation processing on the target communication link between the base station and the adjacent base station includes a first case and/or a second case:
the first condition is as follows: if the target communication link exists between the first cell and the second cell and the request times are lower than a preset first activity threshold, deleting the target communication link;
the first activity threshold is preset, for example, may be a mean value of activity parameters of a plurality of preset adjustment periods multiplied by a first preset coefficient, where the first preset coefficient is smaller than 1; and if the request times are lower than a preset first activity threshold value, which indicates that the utilization rate of the target communication link is low, deleting the target communication link to avoid occupying network resources and adjacent cell resources, so that no resources can be used in a newly-established network and an adjacent cell.
Case two: and if the target communication link does not exist between the first cell and the second cell and the request times are higher than a preset second activity threshold, performing new establishment processing on the target communication link.
The second activity threshold is preset, for example, may be a mean value of activity parameters of a plurality of preset adjustment periods multiplied by a second preset coefficient, where the second preset coefficient is greater than or equal to 1; if a target communication link established through a target interface does not exist between the base station and the adjacent base station and the switching request times transmitted by other non-target communication links are more, a new target communication link is established between the base station and the adjacent base station, so that the signaling congestion caused by the fact that signaling messages and data messages cannot be transmitted in time is avoided.
As a first embodiment, a first activity threshold between base stations is set to 10 times; the second activity threshold value is 100 times, and the preset statistical period is 7 days; the maximum number of X2 or Xn links of the base station 1 to be optimized is 10.
For the X2 or Xn link established between the base station 1 to be optimized and the neighboring base stations 2-10, the statistics of the total number of bidirectional handovers within 7 days are shown in table 3 below:
table 3:
| neighbor base station ID | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Number of switching | 5 | 6 | 100 | 30 | 5000 | 6500 | 800 | 10 | 0 |
For the link between the base station 1 to be optimized and the neighboring base stations 11 to 19, which is not established with X2 or Xn link, the statistics of the total number of bidirectional handovers within 7 days are shown in table 4 below:
table 4:
| neighbor base station ID | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 |
| Number of switching | 15 | 26 | 105 | 300 | 4200 | 500 | 800 | 10 | 7 |
According to the above table 3 and table 4, if the number of handovers between the ID of the base station 1 to be optimized and the ID of the neighboring base station 2, 3, and 10 is less than the threshold 10 of the number of handovers with low activity, the base station to be optimized and the links thereof are deleted according to the policy setting.
Meanwhile, if the switching times between the ID of the base station 1 to be optimized and the ID of the adjacent base station 13-17 are larger than the threshold 100 of the high-activity switching times, the automatic X2 link establishment to the base stations 13-17 is initiated.
After this periodic process is complete, there is an X2 link between base station 1 and the following base stations, as shown in Table 5:
table 5:
| neighbor base station ID | 4 | 5 | 6 | 7 | 8 | 9 | 13 | 14 | 15 | 16 | 17 |
The neighboring base station corresponding to the ID shown in table 5 is the base station that reserves the X2 link with the base station 1 to be optimized.
Optionally, in this embodiment of the present invention, if the target communication link exists between the first cell and the second cell, the request times include a first request time transmitted through the target communication link and a second request time transmitted through a non-target interface; the non-target interface is, for example, an S1 interface, the S1 interface is a communication interface between the eNB and an Evolved Packet Core (EPC), and the S1 interface divides the LTE system into a radio access network and a Core network.
If the activity parameter meets the preset link processing requirement, the step of deleting or newly building the target communication link between the base station and the adjacent base station further comprises the following steps:
and if the difference value between the numerical values of the second request times and the first request times is higher than a preset third activity threshold, deleting the target communication link.
That is, for the value that the number of times of the handover request transmitted via the non-target interface exceeds the number of times of the handover request transmitted via the target interface, which is higher than the third activity threshold, it indicates that the utilization rate of the target communication link is low, and if the number of times of the handover request transmitted via the non-target interface is lower than the third activity threshold, the target communication link is deleted, so that the new network and the neighboring cell are prevented from occupying network resources and neighboring cell resources, which results in that no resources of the new network and the neighboring cell can be used.
As a second embodiment, a first activity threshold between base stations is set to 10 times; the second activity threshold value is 100 times, the third activity threshold value is 1000 times, and the preset statistical period is 5 days; the maximum threshold (maximum number of links) of the base station 1 is preset to be 9.
For the X2 or Xn link established between the base station 1 to be optimized and the neighboring base stations 2-10, the statistics of the total number of bidirectional handovers within 7 days are shown in table 6 below:
table 6:
| neighbor base station ID | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Number of switching | 20 | 7800 | 5900 | 2100 | 250 | 6500 | 8000 | 9000 | 1000 |
For the link between the base station 1 to be optimized and the neighboring base stations 14 and 15, which is not set up with the X2 or Xn link, the statistics of the total number of bidirectional handovers in 7 days are shown in the following table 7:
table 7:
| neighbor base station ID | 14 | 15 |
| Number of switching | 3000 | 4200 |
According to the above table 6 and table 7, all item label communication links of the base station 1 to be optimized do not satisfy the threshold of the switching times of the low activity degree, and the deletion of the X2 link is not triggered; when the sum of the times of bidirectional switching between the base station 1 to be optimized and the adjacent base station 14 exceeds the high activity threshold 100 times, and the number of times of S1 or Ng dual-switching between the base station to be optimized and the adjacent base station 14 is reduced by subtracting the number of times of bidirectional switching between the base station to be optimized and the adjacent base station 14 by X2 or Xn 20, which is equal to 2980 times, and is greater than the threshold 1000 times of the difference of the times of deleting X2 switching triggered by S1 switching, the link between the base station to be optimized and the adjacent base station 2 is deleted, and the link between the base station to be optimized and the adjacent base station 14 is established.
When the sum of the times of bidirectional switching between the base station 1 to be optimized and the adjacent base station 15 exceeds the high activity threshold 100 times, and the number of times of S1 or Ng dual switching between the base station to be optimized and the adjacent base station 15 is 4200, minus the number of times of bidirectional switching between the base station to be optimized and the adjacent base station 6 through X2 or Xn, which is equal to 3950 times, and is greater than 1000 times of a third activity threshold (time difference threshold) for triggering deletion of X2 switching in S1, the link between the base station to be optimized and the adjacent base station 6 is deleted, and the link between the base station to be optimized and the adjacent base station 15 is.
After this periodic process is complete, there is an X2 link between base station 1 and the following base stations, as shown in Table 8:
table 8:
| neighbor base station ID | 3 | 4 | 5 | 7 | 8 | 9 | 10 | 14 | 15 |
The neighboring base station corresponding to the ID shown in table 8 is the base station that reserves the X2 link with the base station 1 to be optimized.
Optionally, in this embodiment of the present invention, if the activity parameter meets a preset link processing requirement, the step of performing deletion processing or new creation processing on the target communication link between the base station and the adjacent base station includes:
and if a newly added communication link request is received and the number of the communication links of the base station reaches a preset maximum threshold value, deleting one or more target communication links with the lowest activity parameters in the target communication links.
The preset maximum threshold value is the maximum number of communication links of the base station, and if the number of communication links reaches the preset maximum threshold value, which indicates that the communication links of the base station reach a fully matched state, one or more target communication links with the lowest preset number of activity parameters need to be deleted to release network resources and neighbor resources, so that the situation that the newly-built network and the neighbor have no resources to use due to the fact that the newly-built network and the neighbor occupy the network resources and the neighbor resources is avoided.
As a third embodiment, a first activity threshold between base stations is set to 10 times; the second activity threshold value is 1000 times, and the statistical period is 7 days; the maximum threshold (maximum number) preset by the X2 links of the base station 1 is 9;
for 9X 2 links established between the base station 1 to be optimized and the neighboring base stations 2 to 10, the statistics of the total number of bidirectional handovers within 7 days are shown in table 9 below:
table 9:
| neighbor base station ID | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Number of switching | 50 | 7800 | 5900 | 2100 | 250 | 6500 | 8000 | 9000 | 1000 |
Triggering X2 establishment due to newly adding neighbor cells between the base station 1 to be optimized and the base stations 11, 12 and 13 in the period, judging that the number of X2 links of the base station 1 to be optimized is full, sequencing the neighbor base stations from small to large according to the X2 switching times in the last period, wherein the sequencing result is 2, 6, 10, 5, 4, 7, 3, 8 and 9.
Firstly, judging that the X2 switching times between the base stations with the IDs of 2 and 6 of the adjacent base stations are less than 1000 times of the threshold of the adjacent cell addition triggering deletion of the X2 link, deleting the X2 link with the base stations and establishing an X2 link between the base stations 11 and 12;
then, if the remaining number of times of switching X2 is not less than 1000, the X2 link is not deleted, and the X2 link is not established with the base station 13.
After this periodic process is completed, there is an X2 link between base station 1 and the following base stations, as shown in table 10 below:
table 10:
| neighbor base station ID | 3 | 4 | 5 | 7 | 8 | 9 | 10 | 11 | 12 |
Referring to fig. 2 as a fourth embodiment, fig. 2 shows a specific embodiment of a communication link processing method according to an embodiment of the present invention, which mainly includes the following steps:
A preset statistical period is preset, for example, a network busy period is included as the statistical period, for example, 7 days. In a preset counting period, counting the times X of switching requests transmitted by a target communication link and occurring in all cells under a base station to be optimized, and the times Y of switching requests occurring through a core network interface without the target communication link, counting the times Z of bidirectional switching between the base station to be optimized and an adjacent base station, taking X, Y, Z as an activity parameter,
for example, 10 handovers (without distinguishing the interface types of the handovers) occur to all cells under the base station to be optimized and the neighboring base station 1, the activity between the base station to be optimized and the neighboring base station 1 is considered to be 10.
All the generated switches are merged according to the home base station of the target cell to obtain the user interaction activity degree in the preset statistical period between the base station to be optimized and the adjacent base station 1, the user interaction activity degree is uniformly sequenced, and the evaluation sequencing result is periodically updated.
And 202, deleting the link with the low activity according to a preset optimization strategy and the activity parameter.
The preset optimization strategy comprises a first activity threshold, wherein the first activity threshold is a link activity over-low threshold; for determining whether to delete the target communication link with the low activity.
For the base station with the switching times less than or equal to the first activity threshold (link activity), the link utilization rate is considered to be too low, the value is low, and the link can be deleted directly.
And step 203, automatically establishing an X2 or Xn link according to the activity between the base stations counted by the S1 port.
And for the adjacent base stations of which the switching times transmitted by the port S1 exceed the X2 switching times within a certain range (for example, higher than a preset third activity threshold), deleting the X2 or Xn link between the base stations with lower activity, and establishing a new link.
And step 204, optimizing the link with the lowest activity according to the activity when the link is full, and adding a new link.
For the situation that the current link is fully configured, if a new link needs to be added, the link with the lowest activity degree in the last complete cycle can be selected for deletion, and the new link is added.
In the embodiment of the invention, the activity parameter of the communication link of the base station is determined; deleting or creating a target communication link between the base station and the adjacent base station according to the activity parameter, and deleting the target communication link with lower activity to avoid occupying network resources and adjacent cell resources so that no resources can be used in a newly created network and adjacent cells; for the cells with higher activity and without target communication link, establishing a target communication link to ensure the timely transmission of signaling messages and data messages; network resources and adjacent cell resources are reasonably scheduled through the activity parameter, and the resource utilization rate is improved; the embodiment of the invention solves the problem that network resources and adjacent cell resources cannot be reasonably utilized due to more communication links and adjacent cell relations of base station equipment in the prior art.

In a wireless communication system, each base station is covered with one or more cells, different cells may be configured to provide different bandwidths; determining activity parameters of all communication links of the base station aiming at the base station, wherein the communication links are communication links from the base station to adjacent base stations, and specifically, when wired communication is carried out, the links refer to physical lines between two nodes, such as cables or optical fibers; in radio communication, a link refers to a space of a path for propagating electromagnetic waves between two nodes, for example, between a base station and a terminal.
The first cell is any cell of the base station, the second cell is any cell of the adjacent base station, and the activity parameter is used for identifying the activity degree of a communication link of the base station and comprises the request times of transmitting a cell switching request between each cell of the base station and the cell of the adjacent base station; the handover direction of the cell handover request may be bidirectional, for example, the handover request may be a handover request for the terminal to be handed over from the first cell to the second cell, or may be a handover request for the terminal to be handed over from the second cell to the first cell.
