S1011, determining at least one communication cell serving the high-speed rail user according to the communication construction parameters, the high-speed rail line diagram and the drive test data.
In practical applications, determining at least one communication cell serving a high-speed rail user according to the communication construction parameters, the high-speed rail line diagram, and the drive test data includes:

Specifically, in order to more accurately determine whether the confirmed communication cell is a high-speed rail cell (the communication cell serving a high-speed rail user is also generally referred to as a high-speed rail cell), the core network, the wireless network device, and the area attribute of the screened high-speed rail cell may be checked, and the accuracy of the attribution information is ensured by checking and confirming the communication cell and the attributive MME pool, MSC pool, SGW pool, TA, LA, and RA information of the communication cell in the communication construction parameters, XDR data, and drive test data.
And S1012, acquiring communication data of the high-speed rail user in the communication cell.
S102, setting configuration parameters of the communication cells meeting preset conditions into specified configuration parameters according to communication data; wherein the preset conditions at least include: the ratio of the sum of TAU signaling, LAU signaling and RAU signaling generated during pool crossing to the sum of TAU signaling, LAU signaling and RAU signaling of the high-speed rail users in the communication cell is greater than or equal to a specified threshold, and the ratio of the high-speed rail users served by the communication cell to all users served by the communication cell is greater than or equal to any one of a first threshold and the ratio of the high-speed rail users served by the communication cell to all users served by the communication cell is greater than or equal to a second threshold; the configuration parameters at least include: any one of pool and area code parameters, the area code parameters at least including: TA, LA and RA.
It should be noted that, in practical application, each communication cell corresponds to a pool, and corresponds to a TA, LA, and RA; the specified configuration parameters can be the configuration parameters of any high-speed rail cell and can also be the reconfiguration configuration parameters; specifically, the technician may set the specified configuration parameters according to the actual situation.
Optionally, the preset conditions include: a first condition; according to the communication data, setting the configuration parameters of the communication cells meeting the preset conditions to be the specified configuration parameters, wherein the configuration parameters comprise:
s1020, when the ratio of the high-speed rail users served by the communication cell to all the users served by the communication cell, and the TAU signaling, the LAU signaling and the RAU signaling generated during pool crossing are determined to meet a first condition, setting the pool of the communication cell to be a designated pool.
It should be noted that, in practical applications, when determining that the ratio of high-speed users served by the communication cell to all users served by the communication cell, and the TAU signaling, the LAU signaling, and the RAU signaling generated during pool crossing satisfy the first condition, setting the pool of the communication cell to the designated pool includes:
at present, core network equipment groups pool of each large operator are basically divided by provinces, so that each province needs to perform combing check on MME/SGSN pool, MSC pool and SGW pool to which a high-speed rail cell in each province belongs.
Because the MME/SGSN pool, MSC pool, and SGW pool corresponding to each communication cell are the same, location area update is required when the high-speed rail user passes through each communication cell, that is, TAU signaling, LAU signaling, and RAU signaling are frequently generated, so that the delay of service request is increased, the success rate of service request is decreased, dropped calls are increased, and the service rate is decreased when the high-speed rail user makes a service request.
In order to solve the above problem, the MME/SGSN pool, MSC pool, and SGW pool of all the high-speed rail cells should be planned as much as possible into one pool (i.e. the MME/SGSN pool, MSC pool, and SGW pool corresponding to each high-speed rail cell are the same), so as to reduce frequent generation of TAU signaling, LAU signaling, and RAU signaling when the high-speed rail user moves across the pool in a fast speed.
The specific operation should be considered comprehensively according to the following aspects: (the specified threshold is 70% and the first threshold is 80%:
judging the signaling sources of the TAU signaling, the LAU signaling and the RAU signaling of the high-speed rail user in the high-speed rail cell, and if the signaling interaction between 70% (the ratio of the sum of the TAU signaling, the LAU signaling and the RAU signaling generated during the pool crossing and the sum of the TAU signaling, the LAU signaling and the RAU signaling of the high-speed rail user in the communication cell is greater than or equal to 70%) and more than 70% of the signaling interaction is from the user when the pool is crossed, considering carrying out pool attribution unification operation on the pool corresponding to the communication cell (i.e. setting the pool of the communication cell to be the designated pool).
Otherwise, if 70% or more of the cells are from discontinuous coverage with the radio network, then no adjustment to the pool of the communication cell is necessary.
Considering whether the high-speed rail cell serves the macro network users at the same time (in practical application, each user served by the communication cell is not only a high-speed rail user, but also includes other macro network users), for example, if the high-speed rail cell serves the high-speed rail users by 80% (the ratio of the high-speed rail users served by the communication cell to all users served by the communication cell is greater than or equal to 80%) or more, the unified adjustment of the pool to the high-speed rail cell should be considered (i.e. the pool of the communication cell is set to the designated pool).
On the contrary, if the high-speed railway cell also serves the large-network users at the same time, wherein the large-network users account for 50% or more of the total number of users (the ratio of the large-network users served by the communication cell to all the users served by the communication cell is greater than or equal to 50%), and when the pool of the communication cell adjacent to the high-speed railway cell is different from the pool of the high-speed railway cell, when the large-network users move between the high-speed railway cell and the peripheral communication cells, frequent operations such as TAU signaling, LAU signaling, RAU signaling and the like are caused due to the need of pool crossing, so that additional burden is added, and at this time, the pool of the high-speed railway cell does not need to be adjusted.
Specifically, the above operation process is generally referred to as checking the planning rationality of MME/SGSN pool, MSC pool, SGW pool.
Optionally, the preset conditions include: a second condition; according to the communication data, setting the configuration parameters of the communication cells meeting the preset conditions to be the specified configuration parameters, wherein the configuration parameters comprise:
and S1021, when the ratio of the high-speed rail users served by the communication cell to all the users served by the communication cell is determined to meet a second condition, setting the area code parameter of the communication cell to be the designated area code parameter.
It should be noted that, in practical applications, when it is determined that the ratio of the high-speed users served by the communication cell to all the users served by the communication cell, TA, LA, and RA satisfy the second condition, the setting of the cell code parameter of the communication cell to the specified cell code parameter includes:
at present, when planning TA, LA and RA, each large operator is usually divided according to the geographical location of a communication cell, so that TA, LA and RA corresponding to communication cells at different geographical locations are different, and thus, when a high-speed rail user passes through each communication cell, operations such as location area update and handover need to be performed.
In order to solve the above problem, it is necessary to set the TA, LA and RA of all the high-speed rail cells to 1 or less number respectively as much as possible to reduce the operations of updating, switching and the like generated across the zones.
Specifically, the TA, LA and RA of all high-speed rail cells should be set to be 1 or less as much as possible, and the actual conditions of provinces and cities need to be considered, for example, in the beijing 3456 loop route in the beijing husband line, if the TA, LA and RA of the high-speed rail are unified, the loop large-network users frequently update across areas, and the network burden is increased; therefore, whether the ratio of the high-speed rail users needing the service of the communication cell to all the users needing the service of the communication cell meets the second condition or not can be judged to not influence the users of the large network when the second condition is met, and the area code parameter of the communication cell can be set to be the designated area code parameter.
Optionally, the method further includes:
s103, determining that the communication cell included in the coverage area of the LA, the communication cell included in the coverage area of the TA, and the communication cell included in the coverage area of the RA are different, and setting the communication cell included in the coverage area of the LA, the communication cell included in the coverage area of the TA, and the communication cell included in the coverage area of the RA as the same communication cell.
It should be noted that, in practical applications, after setting the area code parameter of the communication cell to the specified area code parameter, it is further necessary to confirm whether the communication cell included in the coverage area of LA, the communication cell included in the coverage area of TA, and the communication cell included in the coverage area of RA are the same, and if the communication cell included in the coverage area of LA, the communication cell included in the coverage area of TA, and the communication cell included in the coverage area of RA are different, it is necessary to set the communication cell included in the coverage area of LA, the communication cell included in the coverage area of TA, and the communication cell included in the coverage area of RA as the same communication cell, so that it is not necessary to perform location update when the user moves in a high-speed rail cell with the area code parameters TA, LA, and RA.
Specifically, when the communication cell included in the coverage area of the LA, the communication cell included in the coverage area of the TA, and the communication cell included in the coverage area of the RA are set as the same communication cell, the coverage area of the corresponding LA, the coverage area of the TA, and the coverage area of the RA are also the same.
Optionally, the method further includes:
s104, judging whether the coverage distance corresponding to the LA, the TA and the RA is larger than or equal to the standard coverage distance.
S105, if the coverage distance corresponding to the LA is smaller than the standard coverage distance, adjusting the coverage distance corresponding to the LA to be a first coverage distance; wherein the first coverage distance is greater than or equal to the standard coverage distance.
S106, if the coverage distance corresponding to the TA is smaller than the standard coverage distance, adjusting the coverage distance corresponding to the TA to be a second coverage distance; wherein the second coverage distance is greater than or equal to the standard coverage distance.
S107, if the coverage distance corresponding to the RA is smaller than the standard coverage distance, adjusting the coverage distance corresponding to the RA to be a third coverage distance; and the third coverage distance is greater than or equal to a standard coverage distance, the standard coverage distance is equal to the average minimum vehicle speed multiplied by the minimum driving interval, and the average minimum vehicle speed is equal to the average value of the minimum vehicle speeds of the trains running on the high-speed railway within the coverage distance.
It should be noted that, in an actual application, after setting the area code parameter of the communication cell to the specified area code parameter, it is further required to determine whether the coverage of LA, the coverage of TA, and the coverage of RA are greater than or equal to the standard coverage distance, when the coverage of LA, the coverage of TA, or the coverage of RA is smaller than the standard coverage distance, a tidal effect of a service may occur, which results in an increase in delay of a service request, a decrease in success rate of the service request, an increase in dropped calls, a decrease in service rate, and the like when a high-speed rail user accesses the service.
Therefore, after setting the area code parameter of the communication cell to the designated area code parameter, the coverage distance of TA, LA and RA needs to be adjusted to avoid the tidal effect of service usage.
Wherein the standard coverage distance is equal to the average minimum vehicle speed multiplied by the minimum driving interval. For example, taking the jinghu line high-speed rail as an example, the speed range of the train is 300-; due to the coverage distance of the TA, the coverage distance of the LA and the coverage distance of the RA, high-speed rails pass through a part of the time period, and no high-speed rail passes through a part of the time period, if the coverage distance of the TA, the coverage distance of the LA or the coverage distance of the RA is less than 25km, a short-time tidal effect may be caused due to a sudden increase of traffic load when the high-speed rail passes through.
In particular, tidal effects can also affect service access for large network subscribers if the communication cell is also serving large network subscribers at the same time.
Optionally, the method further includes:
and S108, if the coverage distance corresponding to the LA, the TA and the RA is greater than or equal to the standard coverage distance, determining the adjusted network capacity according to the number of the trains simultaneously existing on the high-speed railway within the standard coverage distance and the rated passenger carrying number of the trains.
It should be noted that, in practical application, after setting the area code parameter of the communication cell to the specified area code parameter, the adjusted service load capability of the network needs to be checked; for example, when the coverage distance of the TA, the coverage distance of the LA, and the coverage distance of the RA are all greater than or equal to 25km, if at most 2 high-speed railways (where the maximum passenger capacity of a high-speed rail normal vehicle is about 500 people and the maximum passenger capacity of a lengthened vehicle is about 1000 people) can exist in the same coverage area at the same time, that is, at most 2000 high-speed rail users exist at the same time every 25km, the number of users should be used as a design basis in the capacity design of the network.
Specifically, if the communication cell serves the large network user at the same time, the data of the current large network user and the capacity number of the network obtained after the adjusted service load capacity of the network is checked need to be combined as a basis for subsequently designing the network capacity.
Specifically, the above process is generally referred to as: and (5) checking the planning rationality of TA, LA and RA.
As can be seen from the foregoing solution, through the parameter configuration of the communication cell provided in the embodiment of the present invention, the configuration parameter of the communication cell that meets the preset condition is set as the specified configuration parameter; therefore, when the high-speed rail user moves in the communication cell using the specified configuration parameters, the position does not need to be updated, namely, a large amount of signaling interaction is not generated, so that the occupation of network resources can be reduced, and the time delay of service access when the user accesses the service is ensured; unlike the prior art, when a train taken by a high-speed rail user passes through each communication cell, the terminal equipment of the high-speed rail user needs to update the area code parameters, so that a large amount of signaling interaction is generated, more network resources are occupied, and the service access delay is higher when the high-speed rail user accesses services; therefore, the problem that the user experience of the high-speed rail user is poor is solved.
