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.
Referring to fig. 1, a flowchart of an embodiment of a parameter maintenance method according to the present application is shown, which may specifically include:
and 102, synchronizing the parameters of the base station node at the base station side to other base stations with the base station nodes with the same parameter values.
In the prior art, in the face of a commercial wireless network consisting of a plurality of base stations, parameter maintenance operation is performed manually; if N base stations are provided, it is necessary to arrange manual parameter maintenance operations for the N base stations, which often consumes a large amount of labor cost.
The inventor of the present application has noticed that, in practice, most base stations have base station nodes with the same parameter values, that is, the base station nodes of most base stations have the same parameter values; since the parameter maintenance operations of the base station nodes with the same parameter value are the same, the prior art arranges manpower for the base stations to perform the same parameter maintenance operations respectively, which consumes workload and labor cost equivalent to the number of the base stations. For example, if there are base station nodes a with the same parameter value in N base stations 1 to N base stations, the prior art needs to spend the workload of N base stations and the labor cost of N base stations to schedule the manually executed parameter maintenance operation of the base station node a for the N base stations, respectively.
For the base station nodes with the same parameter value, the corresponding parameter maintenance operation is the same no matter which base station the base station node belongs to, and finally the parameter value of the base station node is the same; in this way, if the parameter maintenance operation of the base station node is performed only for one base station in a manual mode, and the parameters of the base station side base station node are automatically synchronized to the rest base stations with the base station nodes with the same parameter value, the workload of only one base station is needed, and the labor cost of 1 base station is consumed; when the number of the base stations with the base station nodes with the same parameter value is N, compared with the prior art, the method and the device can save the workload of N-1 base stations and save the labor cost of the N-1 base stations.
In addition, under the condition that the parameter maintenance operation of the base station node is executed only aiming at one base station in a manual mode, and the parameters of the base station side base station node are automatically synchronized to other base stations with the same parameter value, the parameters of all the base station side base station nodes are the same, and the occurrence probability of parameter maintenance error situations such as missing the parameter maintenance operation of a certain base station, missing the parameter maintenance operation of a certain cell, mistaking modified values of certain parameters and the like is very small; therefore, compared with the prior art, the method and the device can improve the accuracy of parameter maintenance.
In practical application, one base station can be appointed as a target base station in a plurality of base stations with base station nodes with the same parameter value, namely, the parameter maintenance operation of the base station nodes is executed in a manual mode aiming at the target base station; and then synchronizing the parameters of the base station node at the target base station side to the rest base stations with the base station nodes with the same parameter values.
Since the parameter synchronization of the base station side base station node to the remaining base stations having base station nodes with the same parameter value is substantially a scheme of parameter synchronization between base stations, the principle of the scheme of parameter synchronization between base stations is roughly that an object of performing parameter maintenance operation of the base station node manually is a target base station, and the remaining base stations having base station nodes with the same parameter value are source base stations.
Referring to fig. 2, a flowchart of embodiment 1 of a method for synchronizing parameters between base stations according to the present application is shown, which may specifically include:
Since the scheme for synchronizing parameters between base stations relates to the scheme for communication between the source base station and the target base station, the following description is made in detail.
Referring to fig. 3, a flowchart of a base station communication method embodiment 1 according to the present application is shown, where the base station is used as a source base station for parameter synchronization, and the method specifically may include:
301, a source base station sends a parameter synchronization request message to a target base station, or the source base station sends a parameter synchronization request message to a core network, and the parameter synchronization request message is transmitted to the target base station through the core network; wherein the parameter synchronization request information carries parameters to be synchronized;
The parameter synchronization request information carries the parameter to be synchronized, and the parameter to be synchronized is mainly used for enabling the target base station to return the value of the parameter to be synchronized. In practice, a person skilled in the art can determine which parameters to be synchronized need to be carried in the parameter synchronization request information according to actual needs. For example, in an application example of the present application, a parameter to be synchronized of a user may be received through a parameter configuration interface of a local LMT tool, and a corresponding parameter synchronization request message is generated according to the parameter to be synchronized.
In another preferred embodiment of the present application, the parameters to be synchronized may specifically include one or more of a base station level parameter and a cell level parameter. In practical application, cell-level parameters needing synchronization can be collected from cells under a source base station.
It can be understood that, besides the parameter to be synchronized, the embodiment of the present application may also carry other information in the parameter synchronization request message, such as a PCI (Physical cell ID) of the source base station, a NodeB ID of the source base station, a cell ID of the source base station, and the like.
In a preferred embodiment of the present application, the parameter synchronization request message may be a binary data stream.
In order to obtain the parameter synchronization request message in the binary data stream format, in another preferred embodiment of the present application, the source base station may further include a local terminal Maintenance tool, an OM (Operations Maintenance) subsystem, and a higher-level subsystem; the method may further comprise:
the local terminal maintenance tool receives a parameter to be synchronized of a user through a parameter configuration interface, and generates a corresponding parameter synchronization request message according to the parameter to be synchronized;
the operation maintenance subsystem informs the high-level subsystem of the parameter synchronization request message;
and the high-level subsystem generates a corresponding binary data stream from the parameter synchronization request message.
The higher-level subsystems herein may vary from one transmission link to another. For example, when an X2 link is adopted, a module X2AP (X2 Application protocol ) may perform PER (compressed encoding rule) encoding on the parameter to be synchronized carried by the parameter synchronization request message to obtain a corresponding binary data stream.
An LTE (Long Term Evolution) network is a next generation mobile radio access system of 3GPP, and includes a core network and an eNB (Evolution base station, Evolution NodeB). The core network and the eNBs are connected in a mesh manner, the core network and the eNBs communicate by using an S1 link, and the eNBs communicate by using an X2 link.
The present application may provide the following scheme for sending the parameter synchronization request information of the source base station to the target base station:
a sending scheme 1, a source base station sends parameter synchronization request information to a target base station;
in a specific implementation, the source base station transmits the parameter synchronization request information to the target base station using an X2 link. Because the X2 link is used for transmitting the parameter synchronization request information, the parameter synchronization request information does not need to be transferred through a core network, so that the time delay of signaling transmission can be effectively saved, and the timeliness of the synchronization parameters between the base stations is provided.
And in the sending scheme 2, the source base station sends a parameter synchronization request message to the core network, and the parameter synchronization request message is transmitted to the target base station through the core network.
In a specific implementation, the source base station transmits the parameter synchronization request message to the core network using an S1 link, and the parameter synchronization request message is transmitted to the target base station via the core network using an S1 link.
Similarly, the present application may provide the following scheme for receiving the parameter synchronization response message of the target base station:
receiving a scheme 1, wherein a source base station receives a parameter synchronization response message returned by a target base station;
and in the receiving scheme 2, the source base station receives a parameter synchronization response message returned by the core network.
It is understood that one skilled in the art can adopt either one of the two transmission schemes and either one of the two reception schemes according to actual requirements. That is, combinations of the transmission scheme 1+ reception scheme 1, the transmission scheme 1+ reception scheme 2, the transmission scheme 2+ reception scheme 1, and the transmission scheme 2+ reception scheme 2 are possible.
In a preferred embodiment of the present application, the method may further include:
and the source base station synchronizes the corresponding parameters to be synchronized of the source base station according to the values of the parameters to be synchronized at the target base station side.
In practical application, a MIB (management information Base) table may be used to record and maintain parameters of a Base station, where a field of a parameter may specifically include parameter information such as a value range and a parameter attribute of the parameter. Meanwhile, a parameter configuration file can be used for describing the values of all parameters when the current base station operates; it can be understood that the parameter configuration file is an aggregate file of some parameters in the MIB table, and the value of the parameter in the file is a given value.
In a preferred embodiment of the present application, the step of the source base station synchronizing the corresponding parameter to be synchronized of the source base station according to the value of the parameter to be synchronized at the target base station side may further include:
updating parameters recorded in a management information base table according to the value of the parameter to be synchronized at the target base station side, and generating a corresponding parameter configuration file; and the parameter configuration file is used for describing the values of all parameters when the current base station operates.

and when the parameters to be synchronized comprise cell level parameters, synchronizing corresponding cell level parameters of the available cells according to the values of the cell level parameters at the target base station side when the available cells are in a closed state, and opening the available cells after synchronization is completed.

Referring to fig. 5, a flowchart of embodiment 2 of a base station communication method according to the present application is shown, where the base station is a target base station for parameter synchronization, and the method specifically may include:
In a specific implementation, the target base station may receive the parameter synchronization request message from the source base station through an X2 link, or receive the parameter synchronization request message from the core network through an S1 link.
After receiving the parameter synchronization request message, the OM subsystem at the target base station side can acquire the value of the parameter to be synchronized at the target base station side from the MIB and carry the value in the parameter synchronization response message; optionally, a corresponding parameter configuration file may be generated according to the value of the parameter to be synchronized at the target base station side, and carried in the parameter synchronization response message.
The present application may provide the following scheme for returning the parameter synchronization request information of the target base station to the source base station:

Specifically, the target base station transmits the parameter synchronization response message to the core network using the S1 link, and the parameter synchronization response message is transmitted to the source base station via the core network using the S1 link.
