Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
Fig. 1 is a flowchart of a shunting method for a high-speed rail private network according to a first embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S101: and identifying the terminal which does not belong to the high-speed rail in operation from the terminals connected with the high-speed rail private network.
The execution subject of this embodiment may be a network device, for example, a radio access network element management system side. In a high-speed rail communication network, a radio network controller on a network side divides a high-speed rail private network into different high-speed rail cells according to a high-speed rail operating line, and each high-speed rail cell is different from cell identifiers of other cells, such as a physical cell identifier (pci). Each high-speed rail cell is similar to a communication cell in a public network and is covered by a base station, namely, in the high-speed rail cell, a terminal connected with a high-speed rail private network communicates with a wireless network controller through the base station. The base station periodically reports the network communication state of the terminal to the radio network controller, for example, the cell connected with the terminal and the connection time thereof, the speed of the terminal, the service type of the terminal, and the like.
In this step, the terminals not belonging to the high-speed rail in operation include terminals used by public network users and terminals used by users who go out of the station when the high-speed rail stops. When the high-speed rail passes through the dense people flow area, part of the terminals which do not belong to the high-speed rail in operation can be connected with the special high-speed rail network, so that the special high-speed rail network is congested, and at the moment, the terminals which do not belong to the high-speed rail in operation can be identified according to the network communication state of the terminals, so that the terminals are shunted out of the special high-speed rail network.
Step S102: and migrating the terminal which does not belong to the running high-speed rail to a low-speed cell in the high-speed rail private network.
In this step, the low-speed cell is a cell corresponding to a certain frequency point or a certain frequency band in the high-speed rail private network, and is used for bearing a terminal that does not belong to the high-speed rail in operation. Specifically, the switching of the cells can be realized by setting the switching parameters configured in the background of the base station.
Step S103: and migrating the terminal connected with the low-speed cell to the public network.
The public network is different from a high-speed rail private network and refers to a public network covering residential areas, scenic spots, business circles and other places. After terminals which do not belong to the running high-speed rail are migrated to the low-speed cell, the terminals are still connected in the high-speed rail private network, and the terminals which are already connected to the low-speed cell are migrated to the peripheral public network by setting the replacement parameters configured by the background of the base station.
In order to ensure that a terminal connected with a low-speed cell can be effectively migrated to a public network, the coverage of the public network is enlarged by sharing a physical address of a high-speed base station and adding a base station of the public network. At present, a public network and a high-speed rail private network adopt a pilot frequency networking mode to avoid interference between the public network and the private network. In order to solve the problem, when a base station covering the high-speed rail private network is constructed, a sector is added on the base station, the sector faces away from a railway and covers users of the public network, and parameters related to the sector are configured as parameters of the public network.
During specific parameter configuration, as one baseband processing unit BBU (building Base band unit) can mount at most 12 Remote radio units RRU (radio Remote unit), and most BBUs in the private network for high-speed rail are all fully mounted with 12 RRUs, for a newly added sector, the RRU corresponding to the sector is mounted by newly adding an independent BBU. Meanwhile, in order to solve the problem of frequency band overlapping, according to the evolution sequence of the private network capacity, when the RRU corresponding to the sector is configured, the probability of sharing the frequency point with the high-speed rail private network is reduced as much as possible, for example, in the evolution sequence of the private network capacity defined by a certain province, D2 is arranged at the rearmost, the frequency point used by the high-speed rail private network is F, and when the RRU corresponding to the sector is configured, the frequency point of the RRU is configured to be D2.
Considering that a cell where a newly added sector is located and a cell in a high-speed rail private network are adjacent cells, when the physical cell identification modulo three values (PCI MOD 3) of the adjacent cells are the same, the same primary synchronization signal and the position of a reference signal overlap occur, so that the switching performance of the cells is affected, and in order to effectively avoid modulo three interference through PCI optimization, the number of base stations of the newly added sector is at most two. When PCI planning is carried out, the three-mode value of the public network and the three-mode value of the high-speed rail private network are required to be staggered so as to ensure that the public network and the high-speed rail private network do not have co-frequency interference. In addition, in order to reduce the difficulty of PCI coordination, a public network is constructed on the sites with dense users in a co-location mode, and at most two base stations are selected in the same logic cell. The base station of the newly added sector must be a single cell, and if the users around the base station are scattered, a plurality of sectors can be set on the base station, and then the corresponding cells are combined.
The embodiment of the invention realizes the shunting of the special high-speed rail network by identifying the terminal which does not belong to the running high-speed rail from the terminals connected with the special high-speed rail network and transferring the terminal which does not belong to the running high-speed rail out of the special high-speed rail network; in addition, when a terminal which does not belong to the running high-speed rail is migrated out of the high-speed rail private network, the terminal is migrated to the low-speed cell firstly, and then the terminal is migrated to the public network, so that the reliability of terminal migration is improved.
Fig. 2 is a flowchart of a shunting method for a private network for high speed rail according to a second embodiment of the present invention, and as shown in fig. 2, compared with the first embodiment, this embodiment is different in that, in this embodiment, identifying a terminal that does not belong to a running high speed rail from terminals connected to the private network for high speed rail further includes the following steps:
step S201: and judging whether the cell switching sequence of the terminal is consistent with a certain part in the cell sequence preset according to the running direction of the high-speed rail, if so, executing the step S202, and if not, executing the step S203.
The preset cell sequence is a cell sequence determined at the time of base station construction, and the sequence is generally consistent with the operation direction of the high-speed rail. During high-speed rail operation, a user connected with a high-speed rail private network can perform cell switching, each cell is different from the marks of other cells, and whether the switching sequence of the actual cell is consistent with a certain part in the preset cell sequence or not is judged according to the marks. For example, in the operation direction of a high-speed rail, the cell sequence of a certain part of the cells is preset to be a-B-C, and when the actual cell switching sequence of the terminal is a-B-C, it may be determined that the cell switching sequence of the terminal is consistent with the preset cell sequence.
Step S202: and judging whether the moving speed of the terminal is smaller than a preset threshold value, if so, executing step S203, and if not, executing step S204.
In this step, the moving speed of the terminal is an instantaneous speed of passing through a cell, and when calculating the speed, it is necessary to calculate using parameters related to two cells in front and rear of the cell. The current passing cell is taken as
The previous cell and the next cell are respectively
For example, the moving speed is calculated by the following formula:
Δt＝ti+1-ti
where theta represents the latitude at which the cell is located,

Step S203: it is determined that the terminal does not belong to a terminal on a high-speed rail in operation.
Step S204: determining that the terminal belongs to a terminal on a running high-speed rail.
In the embodiment of the invention, the terminals belonging to the high-speed rail in operation and the terminals not belonging to the high-speed rail in operation are determined according to the sequence of cell switching and the instantaneous speed passing through the cell, so that the terminals not belonging to the high-speed rail in operation are screened out, and the shunting of the part of the terminals is facilitated.
It will be appreciated that the method of the present embodiment may be used in conjunction with the methods of the previous embodiments.
Fig. 3 is a flowchart of a offloading method for a private high-speed rail network according to a third embodiment of the present invention, and as shown in fig. 3, compared with the first embodiment, this embodiment is different in that, in this embodiment, identifying a terminal that does not belong to a running private high-speed rail from terminals connected to the private high-speed rail network further includes the following steps:
step S301: and acquiring all high-speed rail cells occupied by the terminal in a first preset time.
The first preset time is a time for passing through at least two high-speed rail cells when the high-speed rail is at the lowest speed, for example, assuming that the minimum speed of the high-speed rail is 150km/h and the coverage area of the private network cell is 5km, the time for passing through one cell by the high-speed rail in operation is about 5km/(150km/3600) ═ 120s, that is, 2 minutes passes through one cell, and thus, the time for passing through at least two cells is about four minutes, and the first preset time is set to be five minutes in order to ensure that two cells are passed through.
Step S302: and calculating the residence time of the terminal in each high-speed rail cell.
The residence time in a high-speed rail cell is the time from the first RRU to the last RRU of the high-speed rail passing through the cell.
Step S303: and if the residence time of the terminal in each high-speed rail cell is greater than the second preset time, determining that the terminal does not belong to the terminal on the running high-speed rail.
The second preset time is the maximum time that the high-speed rail in operation stays in one cell. When the high-speed rail runs, the time for the high-speed rail to stay in one cell is less than the second preset time. Taking the calculation result of step S301 as an example, the time for the high-speed rail to pass through one cell is 2 minutes, and in order to improve the reliability of the terminal identification of the non-operating high-speed rail, the second preset time is set to 3 minutes, when the high-speed rail is operating, the residence time of one cell cannot exceed the second preset time, but when the high-speed rail stops, the residence time of the terminal on the high-speed rail in one cell may exceed 3 minutes, but if the user using the terminal does not get off the station, the residence time of the previous cell or the next cell may be less than three minutes. In order to distinguish the terminals used by the users on the high-speed rail when the terminal stops, and improve the identification accuracy, when the time that the terminal stays in each cell is more than 3 minutes, the terminal is determined not to belong to the terminal on the running high-speed rail.
In other embodiments, the method of the second embodiment may be combined in order to distinguish between a terminal used by a user who stops the station and a terminal of a user of the public network. Specifically, if the residence time of the terminal in the current cell is greater than 3 minutes, but the cell switching sequence is consistent with a certain part of the preset cell sequence, and the speed of the previous cell reaches the preset threshold, it may be determined that the terminal belongs to a terminal used by a user who stops the station, that is, a terminal on a high-speed rail in operation, rather than a terminal of a public network user.
According to the embodiment of the invention, the terminal which does not belong to the running high-speed rail is identified through the time of the terminal residing in the cell, so that the terminal which does not belong to the running high-speed rail is moved out of the high-speed rail private network.
It will be appreciated that the method of the present embodiment may be used in conjunction with the methods of the previous embodiments.
Fig. 4 is a flowchart of a shunting method for a private high-speed rail network according to a fourth embodiment of the present invention, and as shown in fig. 4, compared with the first embodiment, the difference of this embodiment is that, in this embodiment, identifying a terminal that does not belong to a running private high-speed rail from terminals connected to the private high-speed rail network further includes the following steps:
Step S401: and acquiring all cells occupied by the terminal in a third preset time.
The application scenario of the embodiment is that an end user on a high-speed rail arrives at a station and gets off the vehicle. The third preset time is the time required for the user to get off the vehicle in a normal situation. When a user gets to a station and gets off the train, the user does not belong to the user in the running high-speed rail, but the user is still connected with the high-speed rail private network, in this case, the user is connected with only some specific cells in the high-speed rail private network, for example, a station cell or a platform cell, and the like. The cells occupied by the terminal on the running high-speed rail in the third preset time are all the cells passed by the high-speed rail in the time. Therefore, the terminal which arrives at the station and gets off the vehicle can be distinguished by the proportion of occupied cells.
Step S402: and calculating the proportion of the number of all cells to the total number of the high-speed railway cells.
Step S403: and if the proportion is smaller than a preset proportion threshold value, determining that the terminal does not belong to a terminal on the running high-speed rail.
The preset proportion threshold is artificially set according to the cell planning during the construction of the high-speed rail cell, and in the implementation of the embodiment, a person skilled in the art can set the value according to the actual situation. When the proportion of all the cells occupied by the terminal to the total number of the high-speed rail cells is smaller than the preset proportion threshold, the terminal is only connected with part of the high-speed rail cells around the platform, and the terminal can be determined not to belong to the terminal on the running high-speed rail.
According to the embodiment of the invention, the terminal which does not belong to the high-speed rail in operation is identified according to the proportion of the high-speed rail cells occupied by the terminal in the total number of the high-speed rail cells in a certain time period, so that the terminal which does not belong to the high-speed rail in operation can be moved out of the high-speed rail private network.
It will be appreciated that the method of the present embodiment may be used in conjunction with the methods of the previous embodiments.
Fig. 5 is a flowchart of a offloading method for a private network of a high speed railway according to a fifth embodiment of the present invention, and as shown in fig. 5, before migrating a terminal connected to a low speed cell to a public network, this embodiment further includes the following steps:
step S501: terminals belonging to the operating high-speed rail in the low-speed cell are identified.
The low-speed cell is a certain cell in the high-speed rail private network and is used for bearing the terminal on the non-running high-speed rail which is moved out from the terminal connected with the high-speed rail private network. Terminals on a high-speed rail in operation may also be connected to a low-speed cell, and in order to migrate terminals on a high-speed rail connected to a low-speed cell back to the private network of the high-speed rail, such terminals need to be identified. Specifically, the terminal connected to the low speed cell may be identified according to the cell identifier of the terminal connected to the cell, and in combination with the method in the foregoing embodiment, the terminal belonging to the high speed train in operation may be identified from the terminals connected to the low speed cell.
Step S502: and moving the terminal belonging to the running high-speed rail back to the high-speed rail private network.
And transferring the terminal which is connected to the low-speed cell and belongs to the running high-speed rail into the high-speed rail private network by changing the replacement parameters configured in the background of the base station.
According to the embodiment of the invention, the terminals belonging to the running high-speed rail in the low-speed cell are identified, and the terminals are migrated back to the high-speed rail private network, so that the terminals are prevented from being migrated into the public network, and the reliability of terminal migration is improved.
Fig. 6 is a flowchart of a shunting method for a private network for high-speed rail according to a sixth embodiment of the present invention, and as shown in fig. 6, compared with the first embodiment, this embodiment further includes the following steps after step S103:
step S601: and identifying the terminal belonging to the high-speed rail in operation from the terminals connected with the high-speed rail private network.
According to the methods of the second to fourth embodiments, the terminal not belonging to the operating high-speed rail can be identified, and the terminal belonging to the operating high-speed rail can be identified by excluding the terminal not belonging to the operating high-speed rail.
Step S602: a current traffic type belonging to a terminal on a running high-speed rail is identified.
The traffic types include voice calls and data traffic. The current service type of the terminal can be identified according to the signaling information when the terminal accesses the internet.
Step S603: and if the current service type is voice call, connecting the terminal belonging to the running high-speed rail with the continuous frequency band of the current cell.
If the voice call service is disconnected, a call drop and a packet loss may be caused, which results in poor user experience, and in order to avoid the call drop of the user who performs the voice call service, when the user initiates the voice call, the frequency band in which the user is located is a continuous frequency band, for example, an F frequency band, the user is left in the frequency band to perform the call service. When the user initiates the voice call, the frequency band in which the user is located is a discontinuous frequency band, for example, a D frequency band, the internet frequency band of the internet terminal used by the user is switched to a continuous frequency band. If the current service type of the user is data service, the short-term call drop does not affect the user experience, so that the frequency band does not need to be switched.
According to the embodiment of the invention, the terminal which belongs to the communication service on the running high-speed rail is connected to the continuous frequency band, so that the terminal which carries out the communication service is prevented from dropping the call, and the user experience is improved.
