Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for establishing a stream control transmission protocol link.
Background
The handover between sites of large communication equipment manufacturers basically depends on the handover of the X2 link, and when two cells of two adjacent sites are successfully established, the current general mechanism is as follows: the X2 link is established by itself, when transmission failure occurs between base stations or transmission instability occurs, if base station reset occurs or base station transmission link failure occurs in a transmission link, under the condition, the X2 link is automatically and repeatedly established after being disconnected, and the phenomenon of link instability occurs, so that the X2 switching index of the X2 link is deteriorated.
The existing process of establishing the X2 link is to configure data between base stations, after configuration is completed, if transmission can be performed, link establishment can be performed, and after establishment is successful, when an exception occurs in a later period, it cannot be automatically determined whether the link needs to be reserved or is not allowed to be established.
1. When there is a problem on the PTN (Packet transport network) side of Transmission between base stations, the base stations try to establish a sctp (Stream Control Transmission Protocol) link of X2. But may have been unsuccessful in establishing success.
2. When two base stations are adjacent, one base station is restarted or the main control board is reset, the X2 link is always detected, and when the X2 link is unstable after the base station is started, the X2 link is continuously tried to be established.
3. When the optical loss of the X2 link between 2 base stations is large, or the optical module is abnormal, a large amount of packet loss may occur, and at this time, the X2 link is always normal, which may cause abnormal handover indexes for the base stations, and pull down KPI (key performance Indicators) indexes.
4. When a PTN side or a network test configures a base station IP (Internet Protocol, inter-network interconnection Protocol) or a base station ID (Identity Document) that is the same as that of a neighboring base station by mistake, the neighboring base station can detect that the IP initiates a mechanism for attempting to establish an X2 link. But have not been established successfully.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In a hot spot area, the number of users is large, the coverage of stations is dense, and the number of base stations is large, so that X2 links of base stations of adjacent cells are configured among the base stations. Thus, the number of X2 links configured for each base station is larger, and the number of users switched by X2 is also larger. When a certain link is unstable or abnormal, switching abnormity occurs at the moment, and the cell of one site is not switched to the cell under another site. After the detection and penalty mechanism for the X2 link is added, if a certain link has a packet transmission failure or a packet loss phenomenon, it may be set that when more than or equal to 20% of packets are lost, the penalty mechanism may be triggered, and the link is not allowed to be established within 1 hour or within 12 hours.
Specifically, the following cases may be included:
1. when the base station a and the base station b are adjacent to each other and the base station b has a problem, the base station needs to be reset, and after the base station is reset, the base station is frequently restarted, or the GPS (Global Positioning System) is unstable, which causes all cells of the base station b to be repeatedly reestablished. Thus, the SCTP link between the base station a and the base station b is repeatedly established, which causes a large number of handover failures between 2 base stations.
After the punishment mechanism is introduced, a data packet with cell state query detection is sent to a b site after the SCTP link detection punishment mechanism is started, the SCTP link punishment mechanism is triggered immediately when the SCTP link is detected to be incapable of being established, so that the SCTP link is not established within 1 hour, if the SCTP link is attempted to be established within 1 hour, the detection data packet is sent after the link is established successfully, if the detection is not problematic, the data packet is normal, if the detection is problematic, the punishment of the next stage is carried out, the punishment time is 12 hours, the detection is carried out after 12 hours, and the detection mechanism is consistent with the 1 hour detection punishment mechanism. The penalty mechanism duration may be X hours and the next penalty period is X +1 hour.
2. When the base station a and the base station B are adjacent to each other, when the base station B is restarted, the X2 link is disconnected, when the base station B returns to normal, the X2 link may be unstable, and the connection may be successful for a while and disconnected for a while. At this time, a SCTP link detection punishment mechanism can be opened, the A base station sends an SCTP link detection data packet to the B base station, and the SCTP link punishment mechanism is triggered in time when the condition that the link is not communicated is detected. Enabling the link to enter a punishment mechanism, enabling the SCTP link not to be established within 1 hour, if the SCTP link is attempted to be established after 1 hour, sending a detection data packet after the link is successfully established, if the detection is not problematic, the link is normal, if the detection is problematic, punishing at the next stage is carried out, wherein the punishment time is 12 hours, and after 12 hours, the detection is carried out, and the detection mechanism is consistent with the 1-hour detection punishment mechanism. The penalty mechanism duration may be X hours and the next penalty period is X +1 hour.
3. When the base station A and the base station B are adjacent base stations, the transmission optical fiber of the base station B is loose, the speed of an optical module is reduced, or the base station B has optical fiber abrasion loss, so that a large amount of data packet loss occurs in a transmission line of the base station. For such a scenario, an SCTP link detection penalty mechanism of the base station may be started, where the a base station first sends an SCTP link detection data packet to the B base station, and automatically filters the detection data packet that is fed back, and when the data packet of the link is less than 20% of the sending packet or the time delay for returning the data packet is very large. And if the SCTP link punishment mechanism is started, punishment is carried out on the SCTP link in time. The SCTP link is not established within 1 hour, if the SCTP link is attempted to be established after 1 hour, a detection data packet is sent after the link is established successfully, if the detection is not problematic, the link is normal, if the detection is problematic, the punishment of the next stage is carried out, the punishment time is 12 hours, the detection is carried out after 12 hours, and the detection mechanism is consistent with the 1-hour detection punishment mechanism. The penalty mechanism duration may be X hours and the next penalty period is X +1 hour.
4. When the PTN side or the network tests the situation that the same base station IP, base station ID, and Cell PCI (Physical Cell Identifier) as the neighboring base station are configured by mistake. At this time, the base station a and the base station B are adjacent to each other, and the IP of the base station C is consistent with that of the base station B due to configuration errors, so that when the SCTP link between the base station a and the base station B is automatically established, if the same base station IP is found, the base station cannot determine which link is established to the end, and at this time, the base station a always tries to establish the SCTP link, but the establishment is overtime each time, and the establishment fails. And at the moment, starting a Stream Control Transmission Protocol (SCTP) link punishment mechanism, and when the condition that the SCTP link establishment is repeatedly triggered due to the fault is automatically detected, immediately triggering the SCTP link punishment mechanism to enable the SCTP link established to the IP to enter the punishment mechanism. The SCTP link is not established within 1 hour, if the SCTP link is attempted to be established after 1 hour, a detection data packet is sent after the link is established successfully, if the detection is not problematic, the link is normal, if the detection is problematic, the punishment of the next stage is carried out, the punishment time is 12 hours, the detection is carried out after 12 hours, and the detection mechanism is consistent with the 1-hour detection punishment mechanism. The penalty mechanism duration may be X hours and the next penalty period is X +1 hour.

A stream control transmission protocol link, i.e. a SCTP link, refers to a link that provides a reliable datagram transmission protocol over protocols based on unreliable transport services.

It can be understood that the SCTP link between the first base station and the second base station may be a single link, or may be multiple links, and specifically, the embodiment of the present application is not limited thereto.
After acquiring the tcp link with the second base station having the neighbor relation, step 102 is performed.

In this embodiment, whether the SCTP link between the first base station and the second base station fails may be periodically detected, that is, whether the SCTP link between the first base station and the second base station fails is detected at preset time intervals, specifically, a detection packet may be sent by the first base station to the second base station through the SCTP link, for example, referring to fig. 3, a schematic diagram of a link detection process provided in this embodiment of the application is shown, as shown in fig. 3, ENB (Evolved Node B, Evolved base station) -a and ENB-B are in an adjacent area relationship, and ENB-a may send the SCTP link detection packet to ENB-B to detect whether the SCTP link between NB-a and ENB-B fails.
After sending the detection packet to the second base station over the stream control transmission protocol link, step 103 is performed.
Step 103: and determining whether the stream control transmission protocol link fails or not based on the sending state of the detection data packet.

In this embodiment of the application, after the first base station sends the detection data packet to the second base station through the SCTP link, it may be determined whether the detection data packet is sent successfully, and specifically, it may be determined whether the detection data packet is sent successfully according to whether the second base station receives the detection data packet, or it may be determined whether the detection data packet is sent successfully according to information returned by the detection data packet according to whether the first base station receives the second base station.
In a specific implementation, it may also be determined whether the detection data packet is successfully sent by using other manners, and specifically, the determination may be determined according to a service requirement, which is not limited in this embodiment of the present application.

Substep A3: and when the sending of the detection data packet fails, determining that the stream control transmission protocol link fails.
When the data packet transmission failure is detected, it can be determined that the SCTP link has failed.

The set threshold refers to a threshold preset by a service person and used for determining packet loss amount in a data packet transmission process, and the set threshold may be set to 20%, 30%, and the like, and specifically may be determined according to a service requirement, which is not limited in this embodiment of the present application.

Substep B3: and when the packet loss is greater than or equal to a set threshold value, determining that the stream control transmission protocol link fails.
When the packet loss amount is greater than or equal to the set threshold, it may be determined that the SCTP link between the first base station and the second base station has failed.
It should be understood that the above two specific implementations are only two examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation on the embodiments of the present application.
After determining whether the tcp link is down based on the detected packet, step 104 is performed.
Step 104: and stopping the establishment of the flow control transmission protocol link within a first preset time under the condition that the flow control transmission protocol link is determined to be in failure.
The first preset time refers to time preset by a service person for stopping establishment of an SCTP link, and the first preset time may be 1h, 2h, and the like, and specifically may be determined according to a service requirement, which is not limited in this embodiment of the present application.
In the case that it is determined that the SCTP link between the first base station and the second base station is failed, the establishment of the tcp link within the first preset time may be stopped, for example, referring to fig. 4, a schematic diagram of not establishing the X2 link according to an embodiment of the present application is shown, as shown in fig. 4, when it is detected that there is a problem in the B base station, a penalty mechanism may be entered, and the X2 link is not established.
According to the embodiment of the application, the optimization and punishment of the SCTP link are carried out through the automatic intelligent judgment of the SCTP link, and the situation that the SCTP link is repeatedly established due to the transmission problem can be greatly improved.

The set threshold refers to a threshold preset by a service person and used for determining packet loss amount in a data packet transmission process, and the set threshold may be set to 20%, 30%, and the like, and specifically may be determined according to a service requirement, which is not limited in this embodiment of the present application.
When the packet loss amount is smaller than the set threshold, it may be determined that the SCTP link between the first base station and the second base station has not failed.
Substep D3: and when the packet loss is greater than or equal to a set threshold value, determining that the stream control transmission protocol link fails.
When the packet loss amount is greater than or equal to the set threshold, it may be determined that the SCTP link between the first base station and the second base station has failed.
It should be understood that the above two specific implementations are only two examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation on the embodiments of the present application.
After determining whether the tcp link is failed based on the detected packet, step 204 is executed, or step 205 is executed.
Step 204: and stopping the establishment of the flow control transmission protocol link within a first preset time under the condition that the flow control transmission protocol link is determined to be in failure.
The first preset time refers to time preset by a service person for stopping establishment of an SCTP link, and the first preset time may be 1h, 2h, and the like, and specifically may be determined according to a service requirement, which is not limited in this embodiment of the present application.
In case it is determined that the SCTP link between the first base station and the second base station is failed, the establishment of the tcp link may be stopped within the first preset time, as shown in fig. 4, and when a problem with the B base station is detected, a penalty mechanism may be entered and the X2 link is no longer established.
According to the embodiment of the application, the optimization and punishment of the SCTP link are carried out through the automatic intelligent judgment of the SCTP link, and the situation that the SCTP link is repeatedly established due to the transmission problem can be greatly improved.
Step 205: transmitting a link down message to the second base station in case it is determined that the stream control transmission protocol link is faulty.
The link down message refers to a message to drop the SCTP link with the second base station.
Under the condition that the SCTP link between the first base station and the second base station is determined to be in failure, the first base station can send a link disconnection message to the second base station, so that the second base station is enabled to definitely disconnect the SCTP link between the second base station and the first base station, and the problem that a terminal under the second base station repeatedly establishes connection for many times is avoided.
Step 206: acquiring an alarm message returned by the second base station; the alarm message contains the failure reason of the stream control transmission protocol link and the link establishment stop time.
When the link disconnection message is sent to the second base station, the second base station simultaneously generates a link disconnection event or alarm to judge whether the link is normal, and after the judgment on whether the link is normal or not of the X2 is carried out by the method, the base station determines whether a punishment mechanism of the X2 link is triggered or not according to the judgment result. When detecting that there is a packet loss condition in a link, a base station triggers a penalty of an X2 link, punishs that the link is not trying to establish the link for 1 hour or 12 hours, and reports an alarm message of X2 link disconnection, where the content in the alarm may include a fault reason of an SCTP link and a link establishment stop time, and specifically, the alarm content may include the following information:
a. no automatic attempt to establish the link is allowed for 1 hour or 12 hours;
b. the ID number of the X2 link and the IP of the opposite end of the link;
c. the reason why the attempt to establish the X2 link is not allowed, for example, there are a large number of packets lost, including how many packets are transmitted and how many packets are lost. The link of X2 is not reachable from the opposite end, and contains the content that the IP of the opposite end and the sending data are not reachable. Or peer-to-peer unreachability is described as peer drop in the reason.
Step 207: and when the first preset time is reached from the beginning of stopping the establishment of the stream control transmission protocol link, detecting the stream control transmission protocol link again.
When the timing is started by notifying the establishment of the SCTP link, and when the first preset time is reached, the SCTP link may be detected again, specifically, the detection packet may be sent again through the SCTP link, and it is determined whether the SCTP link has recovered to be normal based on the sent detection packet.
After the SCTP link is detected again, step 208 is performed.
Step 208: and when the flow control transmission protocol link failure is detected again, stopping the establishment of the flow control transmission protocol link within a second preset time.
The second preset time refers to a stop setup time preset by a service person for stopping setup of the SCTP link between the first base station and the second base station again.
When the SCTP link failure is detected again, the establishment of the SCTP link between the first base station and the second base station within the second preset time may be stopped.
