Description
Technical Field
The invention relates to the technical field of communication, in particular to a method and a device for shutting down a railway base station MIMO channel.
Background
For the communication coverage of the railway, a scheme of a private network is generally adopted, namely, dedicated equipment, dedicated technology, dedicated frequency planning and dedicated parameter planning. Specifically, railway routes are selected in remote suburbs, and in order to provide better network coverage for users on the railway by the base stations, operators set up chain-like base stations along the railway as shown in fig. 1. In the mobile communication system for railways, when a train enters the coverage area of a base station, the base station is awakened, and when the train leaves, the base station is dormant, as shown in fig. 2. Due to the limited coverage of a single station, the train moving at high speed can pass through the coverage of a plurality of base stations in a short time, thereby causing frequent cell switching and further influencing the overall performance of the network.
In order to solve the above problems, a Radio Remote Unit (RRU) common cell technology is generally adopted along a railway, and a plurality of sub-cells under one BBU (Building Base band Unit) physically belong to different sites and logically belong to the same cell. All sub-cells of the common cell keep a receiving state at the moment of the uplink direction and keep the broadcast channel in a transmitting state at the moment of the downlink direction. Although the RRU cell solves the problem of frequent switching of base stations along the railway, the RRU cell also brings huge power consumption problem. All the sub-cells of the common cell can radiate signals outwards no matter whether a train passes through or not, so that resource energy is greatly wasted, and the energy efficiency of a network system is reduced.
Currently, the energy saving technology for railway operation is energy saving in a fixed time period, for example, the railway is not operated at night, and for the time period when the railway is not operated, the base station of the super cell is turned off to save energy. The scheme is not suitable for low-speed motor trains and express trains running at night on part of railway lines, and the flexible energy-saving effect cannot be achieved.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A system architecture applicable to the embodiment of the present invention is shown in fig. 3, and includes a user equipment, an LTE (long term evolution) access network, an LTE core network, a 2G (2-Generation wireless telephone technology)/3G (third-Generation wireless telephone technology) network, and an IP service application background.
The user terminal 101 may be an electronic device with a wireless communication function, such as a mobile phone, a tablet computer, or a dedicated handheld device, and the usage scenario thereof is a railway mobile communication system, such as a high-speed rail, a motor train, an express train, or a general train.
The railway base station MIMO channel shutoff device in the embodiment of the invention is connected with a wireless access network element, acquires user communication data by using various network interfaces, and performs necessary data cleaning and data storage, specifically, acquires user terminal information by interfaces S1-MME, S1-U, S6a and SGI of an LTE network, and acquires user plane data by interfaces Gb and Iupps of a 2G/3G network. And based on the user communication data, calculating the private network cell needing channel switching off, and further determining an MIMO channel list needing switching off in the private network cell.
Based on the system architecture shown in fig. 3, an embodiment of the present invention provides a method for shutting down a MIMO channel of a railway base station, and as shown in fig. 4, the method for shutting down the MIMO channel of the railway base station provided in the embodiment of the present invention includes the following steps:
In the step 401, the first private network cell is selected from the private network cells of the base stations along the railway according to the user communication data of the base stations along the railway in the unit time of the first historical time period; the first channel is selected from all MIMO channels of the first private network cell according to the user communication data.
In the embodiment of the invention, the first private network cell is selected from the private network cells of the base stations along the railway according to the user communication data of the base stations along the railway in the unit time of the first historical time period. And selecting a first channel from all MIMO channels of the first private network cell according to the user communication data. Aiming at a unit time, acquiring a first private network cell needing channel shutoff in the unit time and a first channel needing channel shutoff in the first private network cell; and sending a turn-off instruction to a first base station corresponding to the first private network cell so that the first base station turns off the first channel within unit time. According to the embodiment of the invention, based on the acquired user plane big data, the service conditions of the private network cells of the base stations along the railway are summarized, analyzed and predicted, the shutdown strategy of the private network cell channel is flexibly formulated, the channel shutdown is carried out on the private network cells of the railway base stations on the premise of ensuring the service quality, and the energy consumption of the system is reduced.
In order to facilitate the implementation of the channel switching-off of the private network cell, the first private network cell and the first channel in the first private network cell in step 401 are selected in advance, stored in the database, and directly called when needed.
Therefore, in step 401, before acquiring the first private network cell in which the channel needs to be shut down in the unit time and the first channel in the first private network cell needs to be shut down, the method further includes:
analyzing the user communication data, and determining crowd characteristic data or determining GIS (Geographic Information System or Geo-Information System) Information of the user;
calculating overlapping coverage crowd according to the crowd characteristic data and MR (Measurement Report) data or according to GIS (geographic information system) information of the user;
determining the number of users in each private network cell in the unit time according to the overlapping coverage crowd;
and determining the first private network cell from all private network cells according to the number of the users.
In particular implementations, the demographic data may be determined in the following manner. User communication data are collected through various network interfaces, and the user terminal information, the terminal use information and the like are utilized to distinguish the crowd characteristics of users of the terminal. For example, the terminal user group of the newer version of Android/iphone is generally a young person; the 2G/3G terminal has the characteristics of simple function and low cost, and the user group is generally the old user; the user of the child telephone watch is a child or the like. The crowd characteristics can be distinguished through terminal use information, such as APP in the terminal, including sharing bicycle, GPRS thing networking, M2M network (intelligent water meter ammeter, health monitor, conflagration and safety alarm etc.). Therefore, the embodiment of the invention can realize the behavior track tracking, gender, age, special group judgment and the like of the railway passenger group according to the related data of the user terminal.
On the other hand, the embodiment of the invention also acquires user GIS information, such as passenger attribution, roaming place and the like, by data acquisition and analysis of the signaling monitoring system, and carries out statistics and behavior analysis on the railway passenger condition.
For the location positioning of the 2G base station, an a interface link of the network may be monitored, so as to obtain an LAC (location area code) and a CI cell Number, a TMSI (International Mobile Subscriber Identity), or an IMSI (International Mobile Subscriber Identity) where a railway passenger is located. The a interface signaling message to be collected includes: location update of LAC area, periodic location update, MS (mobile station) detach, MS attach, MOC, MTC. Monitoring related MSC (main service channel) surrounding link, aiming at obtaining the corresponding relation between the IMSI and MSISDN (Mobile subscriber number) of the user according to the 'location update' process of MAP, so as to judge the attribution of the user according to the MSISDN number. And associating the same 'location updating' process according to the user information of the interface A and the user information of the MAP message and the association rule to obtain a final user record. In a mobile network, when a visiting user changes the position across an LAC area, a normal position updating process can occur, and a system can detect in time and perform response processing. In the link of the a interface, TMSI information of the user, the LAC area where the user originally was located, and the LAC area and Cell _ ID where the user arrived may be detected, which process is certainly performed in the mobile network, and thus GIS information of the user may be surely obtained, thereby providing information service to the user. For mobile phone users in the same LAC area coverage area, the cell where the user is located can be detected through communication events such as periodic update, IMS attachment (user startup), IMSI separation (user shutdown), call establishment (MOC, MTC), short message process (MTSM, MOSM) and the like, so that the specific position of the user is determined.
For the location positioning of the mobile 4G base station, a CGI (Cell Global Identity) is a unique identifier of a wireless network Cell in a Global scope, and different networks of different operators may have different CGI numbering rules. Since eNodeBID is a number of a base station and is unique in the LTE network, a Cell ID formed by eNodeBID and a Cell ID is also unique in the LTE network. Such Cell ID plus network number (PLMN ID) can guarantee global uniqueness, i.e. CGI, of the LTE Cell. The global Identity of the Cell of LTE is called ECGI (eUTRAN Cell blob Identity). After ECGI data are obtained, the positioning of the mobile 4G LTE can be realized through a network management system, and the longitude and latitude and geographic GIS information of a corresponding base station are obtained.
According to the embodiment of the invention, the overlapping coverage crowd can be determined according to the crowd characteristic data and the MR data, or the overlapping coverage crowd can be calculated according to the GIS information of the user. In mobile networks such as railways, users often have a change in location across cells, so that when calculating the number of users, repeated calculations occur, and the number of overlapping coverage people needs to be subtracted.
In the embodiment of the invention, different energy-saving processing can be carried out aiming at different private network cells according to the number of users. Specifically, the number of users in a private network cell may be compared with a first threshold and a second threshold for the private network cell, and if the number of users is greater than the first threshold and the number of users is less than the second threshold, the private network cell is used as the first private network cell to perform turn-off processing on part of the MIMO channels; if the number of the users is smaller than a first threshold value, all channels of the private network cell are permanently shut off; if the number of the users is larger than the second threshold value, the load of the private network cell is heavier, and channel shutoff processing is not performed.
For example, in a certain western high-speed railway station cell, the data traffic is below 300M every day in one month, the condition of permanent consumption reduction is met, and all channels can be shut down. In addition, within 15 continuous days, if the utilization rate of the dormant resources in a certain high-speed railway station cell is more than 4 hours, the static consumption reduction is met; part of the channels can be continuously shut off.
Furthermore, a channel which needs to be shut down in the first private network cell needs to be determined. Before step 401, further comprising:
determining the number of first channels needing to be shut down in the first private network cell according to the number of users in the first private network cell and/or the traffic of the first private network cell;
verifying the number of the first channels by utilizing the channel turn-off condition of the first private network cell in a second historical time period;
and if the difference between the channel closing condition of the first private network cell and the number of the first channels is smaller than a third threshold value, selecting the first channels from the first private network cell according to the number of the first channels.
Specifically, the number of first channels that need to be turned off in the embodiment of the present invention may be calculated according to the following formula:
wherein, M i,j The number of first channels needing to be shut off for a private network cell i and a private network cell j respectively is equal, the private network cell i belongs to a private network base station D, the private network cell j belongs to a private network base station F, the private network base station D and the private network base station F are two adjacent private network base stations along a railway, and the number of the first channels in the private network cell i is equal to that in the private network cell j;
is the maximum traffic when the private network base station D does not turn off the first channel in all unit times of the first historical time period,
the average traffic volume when the private network base station F shuts down the first channel for all the unit times of the first history time period,
is the maximum number of users when the private network base station D does not turn off the first channel in all unit times of the first historical period,
and the average number of users when the first channel is closed by the private network base station F in all unit time of the first historical time period.
In addition, when the number of users is particularly small, the number of the first channels needing to be shut down can also be calculated only according to the traffic volume, and at this time, the number of the first channels needing to be shut down can be calculated according to the following formula:
in general, after calculating the number of first channels to be turned off, M can be selected from all MIMO channels of the private network cell D,F The first channel is shut off.
In order to increase the accuracy of calculation, the number of the first channels is checked by using the channel turn-off condition of the first private network cell in a second historical time period. For example, if the second historical time period is a day cycle, the channel shutdown condition of the first private network cell in the unit time of the previous day is acquired, and the calculated number of the first channels on the current day is checked. And if the difference between the first channel and the second channel is smaller, selecting the first channel from the first private network cell according to the calculated number of the first channels to shut down. If the difference between the two is large, an alarm can be given.
In the process of switching off the first channel of the first private network cell, the service of the first private network cell can be undertaken by using the compensation cell. In the prior art, there is only one-to-one energy saving scenario, that is, the service of one private network cell can only be borne by one compensation cell corresponding to the private network cell. The private network cell in the embodiment of the invention has no unique compensation cell and can be covered by a plurality of compensation cells at the same time. Therefore, after determining the first private network cell which needs to be turned off in unit time and determining the first channel which needs to be turned off in the first private network cell according to the user communication data, the method further includes:
determining a compensation cell corresponding to the first private network cell;
selecting a second cell from the compensating cells;
and sending a wakeup instruction to a second base station corresponding to the second cell so that the second base station wakes up a channel of the second cell in the unit time.
Specifically, when the first channel of the first private network cell is cut off, the compensation cell is screened, and the specific screening basis can be that the traffic of the private network cell in the unit time of the first channel cut off is predicted, and then a second cell is selected from all compensation cells of aunt private network cells by combining the state of each compensation cell, and the compensation is carried out on the first private network cell in the unit time.
Further, the embodiment of the present invention further evaluates the turn-off effect of the first channel, so as to guide the selection of the first channel in the subsequent first private network cell. The sending a shutdown instruction to a first base station corresponding to the first private network cell so that the first base station shuts down the first channel in the unit time further includes:
evaluating the number of the first channels to obtain an evaluation result;
obtaining the service condition of the user terminal after the first channel is cut off;
and determining a first channel needing to be shut down in the first private network cell by using the use condition of the user terminal and the evaluation result.
The scoring of the number of first channels satisfies the following formula:
wherein the content of the first and second substances,
for the scoring result of the number of the first channels, the number of the first channels turned off by the private network base station D is equal to that of the first channels turned off by the private network base station F, and the number of the first channels is L. The above scoring of the number of first channels
The smaller the better.
In addition, the first channel needing to be shut down in the first private network cell is further accurately determined by using the use condition of the user terminal.
For example, natural attribute feature identification of end user gender a, age b, recipient c, education level d, etc. is first performed. And then, identifying the behavior attribute characteristics of the terminal user, wherein activities on a high-speed rail and a motor car mainly comprise reading, and most mainly comprise watching scenery outside a window, sleeping or nap. Behavior attribute features that can be set include the following: 1 watching scenery outside the window, 2 closing eyes and cultivating spirit/sleeping, 3 sending short messages, 4 chatting/playing cards with others, 5 listening to train broadcasting, 6 listening to music, 7 receiving/playing mobile phones, 8 watching leisure reading materials such as newspaper, magazine, novel and cartoon, 9 reading/learning professional books, 10 using a self-contained computer to entertain or process documents, 11 watching television on the train and the like. After the railway passenger database is established by the method, the evaluation value of each user attribute characteristic on the channel shutdown benefit can be calculated, so that the targeted tracking service of the railway passengers is realized. And planning the MIMO channel turn-off scale based on big data analysis of the wireless signaling and according to the evaluation value of the user attribute characteristics on the channel turn-off benefit, training different MIMO channel turn-off models for different cells of the base stations along the railway, and performing refined MIMO channel turn-off prediction and selection. For example, if there are many users on the internet among the railway passengers, the channel related to the traffic is selected to be closed, and the channel related to the traffic is opened.
The evaluation value of the channel shutdown benefit by the user attribute feature can be calculated by the following formula:
h is an evaluation value of the user attribute characteristics on the first channel turn-off benefit; y is D,F The influence degree of the user attribute characteristic on the number of the first channels can be obtained by calculation according to the traffic volume occupied by the terminal according with the user attribute characteristic under the condition that the first channel is closed, the traffic volume of each channel which is not closed under the condition that the first channel is closed and the traffic volume of the whole base station; and T is a first channel turn-off effect scoring time factor, and is obtained according to the following formula:
where T remains within the [ O, l ] range and T is the number of days the first channel was shut off during the first historical time.
In order to more clearly understand the present invention, the following detailed description of the above process is provided by using a specific embodiment, and the specific steps are shown in fig. 5, and include:
step 501: user communication data of the base stations along the high-speed rail of a unit time in one month is acquired, wherein the unit time can be 15 minutes, such as user communication data of 10 o 'clock to 10 o' clock 15 minutes in the morning.

And realizing the positioning of the home base station according to the cell LAC and CI or CGI attached to the user terminal, and acquiring the longitude and latitude and geographic GIS information of the corresponding base station.

That is, the number of channels turned off by the first private network cell within 15 minutes from 10 am to 10 am of the previous day is obtained, the obtained number of channels is compared with the number of the first channels, if the difference between the obtained number of channels and the number of the first private network cell is smaller than a third threshold value, step 507 is executed, and otherwise step 508 is executed.
