Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Some concepts mentioned in the embodiments of the present invention are first explained as follows.
Time Division Long Term Evolution (TD-LTE) adopts Time to distinguish uplink and downlink, and its resources in one direction are discontinuous in Time and need to protect Time intervals to avoid interference between transmission and reception between two directions, so a corresponding frame structure is defined; if the frame structure settings of adjacent co-frequency cells are not consistent, interference can result.
A Radio Remote Unit (RRU) frame header offset indicates a delay time of a start of a cell air interface frame with respect to a reference clock source, and similarly, if frame header offsets of adjacent cells with the same frequency are also set to be inconsistent, interference may also be generated.
In order to avoid interference, the TD-LTE base station requires that the frame structure and the frame head bias of the same frequency point configuration are consistent. However, since the frame structure and the RRU frame header offset have multiple values, and various values are reasonable for a single station, the situation of manual configuration inconsistency often occurs. If the adjacent base stations are inconsistent, interference is generated immediately, key indexes are reduced, and user perception is reduced. When such problems occur, if the recovery cannot be carried out in time, the influence on the network is great.
When the TD-LTE is started or optimized, an engineer determines the frame structure and frame header offset of a cell according to the planning, corresponding scripts and formats are manufactured, batch import and addition are carried out through network management, the network side checks the legality and format of related fields of input information, and the cell can be successfully established as long as the key fields and the format are legal.
When a cell is newly added or modified, the current base station and OMC only check the data validity of a frame structure and a frame header bias, which causes the frame structure and the frame header bias to be successfully added only by a format legal method, and causes interference. Moreover, problems caused by such a situation are difficult to be eliminated in massive base stations, and the perception of customers is continuously influenced before the problems are not solved.
As shown in fig. 1, a cell configuration method in a time division system according to an embodiment of the present invention is applied to a cell configuration device in a time division system, and includes:
it should be noted that, the first information is a cell frame structure and/or a frame header offset; when first information of a service cell needs to be increased, the first information comprises a cell frame structure and frame header offset; when the first information of the serving cell needs to be modified, the first information includes a cell frame structure and a frame header offset, or the first information includes a cell frame structure, or the first information includes a frame header offset.
it should be noted that the reference value is used to check the first information to ensure that the information of the serving cell and the information of the neighboring cell corresponding to the first information are consistent, so as to avoid interference.
It should be further noted that, before step 11, the method for configuring a cell in a time division system further includes:
acquiring configuration information of a neighboring cell having the same frequency point as the serving cell; and determining a reference value corresponding to the first information according to the configuration information of each adjacent cell.
It should be noted that the configuration information includes: the frame structure and/or the frame header offset, specifically, when the first information is a cell frame structure, the configuration information includes: a frame structure; when the first information is a frame header offset, the configuration information includes: frame header biasing; when the first information is a frame structure and a frame header offset, the configuration information includes: frame structure and frame header offset.
Further, according to the configuration information of each neighboring cell, the manner of determining the reference value corresponding to the first information is as follows: and counting the occupation ratio of each type of configuration information in the configuration information of each adjacent region, and taking the configuration information with the highest occupation ratio as a reference value corresponding to the first information.
It should be noted that, in a general case, the cell configuration device in the time division system obtains the information of the whole network in the early morning period (the network usage rate in this period is low, and the network usage rate is not affected), counts the proportion of each piece of configuration information in the configuration information of the neighboring cells having the same frequency point in all the cells corresponding to the first information, and uses the configuration information with the largest proportion as the reference value corresponding to the first information.
For example, if the frequency point corresponding to the first information is frequency point a, the cell configuration device in the time division system obtains the configuration information of all neighboring cells whose frequency point corresponding to the serving cell is frequency point a, for example, the configuration information of all neighboring cells totally includes 3 types, where configuration information 1 accounts for 80%, configuration information 2 accounts for 10%, and configuration information 3 accounts for 10%, and then the cell configuration device in the time division system takes configuration information 1 as a reference value.
It should be noted that, in the time division system, the cell configuration device may pre-count and obtain a reference value corresponding to each frequency point (i.e., a cell frame structure and/or a frame header offset corresponding to each frequency point) and store the reference value to facilitate subsequent use, and the reference value corresponding to each frequency point is periodically updated to ensure accuracy of information.
It should be further noted that, in order to prompt a network optimization engineer in time when the first information is inconsistent with the reference value, in the embodiment of the present invention, when the serving cell is configured by using the first information, after comparing the first information with the reference value, the method further includes:
if the first information is inconsistent with the reference value, displaying alarm information;
wherein the warning information is used for indicating that the first information is inconsistent with the reference value.
It should be noted that the alarm information may be displayed on a screen of a cell configuration device in the time division system in a pop-up window manner, or may be prompted by a network optimization engineer in a voice manner, the optimization engineer checks the data according to the prompt, and after the checking is completed, the relevant data is imported again until the checking is successful.
It should be further noted that, before step 11, in order to ensure that the first information for configuration meets the usage requirement, the method for configuring a cell in a time division system according to the embodiment of the present invention further includes:
carrying out numerical value validity check on the first information; and if the numerical value validity of the first information passes the verification, comparing the first information with a reference value.
Only the first information which passes the numerical value validity check is compared with the reference value, and when the comparison is consistent, the first information is configured, so that the configured information can meet the use requirement.

and 29, modifying the first information by the optimization engineer, and jumping to the step 22 to continue to execute the adding or modifying process until the information is successfully added or modified.
It should be noted that, in the time division system according to the embodiment of the present invention, the cell configuration apparatus may be an OMC.
