Description

Fence cell establishing method and device

Technical Field

The present disclosure relates to the field of fence cells, and in particular, to a method and an apparatus for establishing a fence cell.

Background

Based on the wide application of the current big data analysis in various industries, particularly the big data analysis based on the geographic position information, powerful data support is provided for launching of shared bicycles, dispatching of public transport systems and the like. How to acquire information of a wide geographical position is an urgent problem to be solved. Currently, the IMSI number (International Mobile Subscriber Identity) of the Mobile phone is obtained through the network fence device, and then the approximate geographic location of the network fence device is inferred through the location of the fence device, so as to complete the collection of big data.

The current IMSI code acquisition methods are all based on cell reselection of an idle terminal, access to fence equipment, and the fence equipment issues an inquiry command to acquire the IMSI code of the terminal. The cell reselection is divided into a pilot frequency high priority reselection scheme and a same frequency reselection scheme. For the pilot frequency high priority reselection scheme, the scheme requires that a public network cell around a point for installing the fence equipment has a pilot frequency high priority neighbor cell, and the neighbor cell of the frequency point does not exist in the coverage of the surrounding public network. After the conditions are met, the fence equipment establishes the fence cell by taking the pilot frequency high-priority frequency point configured in the public network cell of the public network as a station establishing frequency point. For the same-frequency reselection scheme, information such as Reference Signal Receiving Power (RSRP), physical Cell Identifier (PCI), frequency point, etc., of a public network Cell in which the terminal resides needs to be obtained. And the fence equipment establishes fence cells with the same frequency by adopting the same frequency points as those of the public network cells in which the fence equipment resides.

The inter-frequency high priority scheme has strict requirements on the public network environment, and an operator is required to modify the inter-frequency high priority related configuration in a matching manner. However, in actual use, coordination with an operator is troublesome, coordination is very easy to fail, if no operator configuration exists, an environment meeting the different frequency scheme is basically not provided, and a use scene is greatly limited. In the same-frequency reselection scheme, the signal strength of the public network cannot be too strong, otherwise, the terminal cannot initiate measurement due to the fact that the terminal cannot meet the same-frequency measurement threshold, and therefore the terminal cannot reselect the public network cell of the fence device.

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.

At present, the big data analysis based on the big data analysis is widely applied to various industries, and particularly, the big data analysis based on the geographical position information provides powerful data support for launching of shared bicycles, site selection of shops, dispatching of public transport systems and the like. How to acquire information of a wide geographical location, even location information of a specific target person, becomes a problem to be solved urgently. In the embodiment of the application, the IMSI of the terminal is acquired through the fence device, and then the approximate geographic location of the terminal is deduced by acquiring the location of the network fence device, so as to complete the collection of the big data. And, because the IMSI is unique, approximate range locking to a specific target can also be achieved.

Referring to fig. one, a schematic diagram of a conventional international mobile subscriber identity acquisition method is shown, which includes a specific process that a user equipment sends a radio resource control connection request to a base station, the base station sends a radio resource control connection configuration to the user equipment, the radio control connection between the user equipment and the base station is completed, the user equipment sends a tracking area code update request back to the base station, the base station sends a request confirmation message to the user equipment through downlink information transmission, the user equipment sends a confirmation response to the base station through uplink information transmission, the base station replies a tracking area code update reject message to the user equipment due to the absence of a suitable cell in a tracking area, and performs radio resource control connection release, the base station pages the user equipment, changes the tracking area code according to the configuration, and the user equipment sends a radio connection control connection request to the base station again, and in this process, the base station can acquire an IMSI of a terminal by sending a query message.

The conventional IMSI number acquisition method is to access the fence device by cell reselection of the idle terminal, and the fence device issues an inquiry command to inquire the IMSI number of the terminal. The cell reselection is divided into a pilot frequency high priority reselection scheme and a same frequency reselection scheme. The inter-frequency high priority scheme has strict requirements on the public network environment, and an operator is required to modify the inter-frequency high priority related configuration in a matching manner. However, in actual use, coordination with an operator is troublesome, coordination is very easy to fail, if no operator configuration exists, an environment meeting the different frequency scheme is basically not provided, and a use scene is greatly limited. In the same-frequency reselection scheme, the signal strength of the public network cannot be too strong, otherwise, the terminal cannot initiate measurement due to the fact that the terminal cannot meet the same-frequency measurement threshold, and therefore the terminal cannot reselect the public network cell of the fence device.

In view of the above disadvantages in the prior art, one of the core concepts of the embodiments of the present application is: the network fence equipment obtains a plurality of public network cells through scanning, then obtains neighbor cell configuration information of the public network cells, then determines a specific public network cell in the public network cells, adopts the neighbor cell configuration information of the specific public network cell to generate a parameter list, and finally establishes a fence cell according to the parameter list, thereby realizing automatic scanning of the site environment of the network fence equipment, automatically selecting suitable neighbor cell configuration information, establishing the fence cell, needing no manual work to coordinate with an operator to modify the cross-frequency high-priority related configuration of the public network, greatly reducing the tedious workload and labor cost brought by manual selection and reselection schemes for establishing the fence cell, and in addition, the network fence equipment can establish a plurality of fence cells with different frequency points according to the parameter list, and automatically obtaining international mobile subscriber identification codes of terminals residing on different public networks under the condition of realizing the coverage of the public network cells with the plurality of frequency points.

Referring to fig. 1, a flowchart illustrating a step of a first method for establishing a fence cell according to the present application is shown, which may specifically include the following steps:

step 101, a network fence device obtains a plurality of public network cells through scanning;

in this embodiment, the network fence device may include a baseband processing device, a filter, and a power amplifier. The baseband processing device runs with a scanning module, a protocol stack software and a base station management unit. And when the periphery does not have any other cell, only the cell established by the baseband processing device, the baseband processing device can independently complete the access process of the terminal. In addition, the filter is used for effectively filtering the frequency of the electric signal sent by the baseband processing device to obtain a signal with a preset frequency, and the power amplifier is used for amplifying the signal of the baseband processing device.

In addition, the public network cell of the application is a cellular cell based on a public network. The public network is also called a wide area network, and is a remote network for connecting computers in local area networks or metropolitan area networks in different regions for communication. A cell is an area covered by a base station or a part of a base station in a cellular mobile communication system, in which a mobile station can reliably communicate with the base station through a radio channel.

After the network fence equipment is started, a scanning module on the baseband processing device is in a monitoring mode, and scans the area where the fence equipment is located, and a plurality of public network cells covered by the area are sequentially identified.

102, obtaining neighboring cell configuration information of the public network cells;

after the network fence equipment identifies a plurality of public network cells covered by the area where the network fence equipment is located, synchronization with the public network cells is realized by solving the main and auxiliary synchronization signals broadcast by the public network cells. After the network fence device and the public network cell are synchronized, the network fence device can acquire the neighboring cell configuration information broadcasted by the public network cell. The neighboring cell configuration parameters include related configuration parameters of the public network cell.

Step 103, determining a specific public network cell in the public network cells;

after acquiring the neighboring cell configuration information of the multiple public network cells, the network fence device analyzes the neighboring cell configuration information of the multiple public network cells, and selects a suitable public network cell from the multiple public network cells as a specific public network cell according to the analyzed information, wherein the network fence device can determine the multiple specific public network cells.

Step 104, generating a parameter list by adopting the neighboring cell configuration information of the specific public network cell;

after selecting a suitable public network cell from a plurality of public network cells as a specific public network cell, the network fence device generates a parameter list by using the neighbor cell configuration information of the specific public network cell, where the parameter list may include one or more neighbor cell configuration information of the specific public network cell.

And 105, establishing a fence cell according to the parameter list.

And after the network fence equipment generates a parameter list by adopting the neighbor cell configuration information of the specific public network cell, establishing a fence cell according to the parameter list. If the parameter list contains the neighbor cell configuration information of a plurality of specific public network cells, the network fence equipment sequentially adopts the neighbor cell configuration information of the specific public network cells in the parameter list to establish fence cells, and each fence cell is deleted after keeping for a certain time and then establishes the next fence cell. When the terminal enters the fence cell established by the network fence equipment and meets reselection conditions, the terminal can access the fence cell, and at the moment, the network fence equipment can send the international mobile subscriber identity request message to the terminal, so that the international mobile subscriber identity of the terminal is acquired.

In the embodiment of the application, the network fence equipment obtains a plurality of public network cells through scanning, then obtains the neighbor cell configuration information of the public network cells, then determines a specific public network cell in the public network cell, adopts the neighbor cell configuration information of the specific public network cell to generate a parameter list, and finally establishes the fence cell according to the parameter list, thereby realizing the site environment where the network fence equipment is automatically scanned, automatically selecting the appropriate neighbor cell configuration information, establishing the fence cell, and not needing manual work and operators to coordinate and modify the cross-frequency high-priority related configuration of the public network, thereby greatly reducing the tedious workload and labor cost caused by manually selecting a reselection scheme to establish the fence cell.

Referring to fig. 2, a flowchart illustrating steps of a second method for establishing a fence cell according to the present application is shown, which may specifically include the following steps:

step 201, a network fence device obtains a plurality of public network cells through scanning;

in an optional embodiment of the present application, the step of the network fence device obtaining a plurality of public network cells through scanning may include the following sub-steps:

step S11, the network fence equipment acquires a plurality of frequency point information from a preset storage position;

the frequency point refers to a specific absolute frequency value, and is generally the center frequency of the modulation signal. The frequency bins are numbered by fixed frequencies, for example, the frequency band of GSM900 (global system for mobile Communications ) can be divided into 125 frequency bins (124 frequency bins are actually available). Wherein 1-94 belong to China Mobile, 96-124 belong to China Unicom, and 95 is reserved to distinguish two operators.

In the embodiment of the application, the preset storage position of the network fence device stores frequently-used frequency point information of each large operator, and the network fence device accesses the preset storage position to acquire all locally-stored frequency point information.

And S12, scanning by the network fence equipment by using the frequency point information to obtain a plurality of public network cells.

After the network fence equipment acquires all locally stored frequency point information, a plurality of public network cells covered by the area where the network fence equipment is located can be identified by scanning all the frequency point information.

Step 202, obtaining neighboring cell configuration information of the plurality of public network cells;

step 203, determining a specific public network cell in the public network cells;

in this embodiment, the network fence device of the present application needs to select a suitable parameter to establish a fence cell, so as to obtain an IMSI number accessed to the network fence cell, and therefore, the network fence device needs to determine a specific public network cell meeting a condition from a plurality of public network cells first.

The specific public network cell includes a first public network cell, and the step of determining a specific public network cell in the public network cell may include the sub-steps of:

substep S21, obtaining reference signal receiving power of the plurality of public network cells;

RSRP (Reference Signal Receiving Power) is one of the key parameters that can represent the wireless Signal strength in an LTE network and the physical layer measurement requirements, and is the average of the received Signal Power over all resource elements that carry Reference signals within a certain symbol.

After the network fence device and the public network cells are synchronized, the network fence device measures the reference signal received power of the plurality of public network cells, and a specific measurement method is not further limited in this embodiment of the present application.

And a substep S22 of extracting a public network cell with reference signal received power satisfying a first preset condition from the plurality of public network cells as the first public network cell.

In an alternative embodiment of the present application. The first preset condition may include a preset ranking, and the step of extracting, from the plurality of public network cells, a public network cell whose reference signal received power satisfies the first preset condition as the first public network cell may include:

sequencing the reference signal receiving power of a plurality of public network cells;

and determining the public network cell corresponding to the reference signal receiving power meeting the preset ranking as a first public network cell.

For example, after the network fence device scans a plurality of public network cells with different frequency points, the preset ranking is set to be the first three, and after the reference signal received powers of the plurality of public network cells are sequenced, the public network cells meeting the preset ranking of the first three are cell a, cell B and cell C, the network fence device determines the cell a, the cell B and the cell C as the first public network cell

In another optional embodiment of the present application, the first preset condition may be that the reference signal received power is greater than a preset threshold, and then the public network cell that satisfies that the reference signal received power is greater than the preset threshold is determined as the first public network cell.

The specific public network cell further comprises a second public network cell, and the step of determining a specific public network cell in the public network cell may further comprise the substeps of:

and a substep S31, extracting the public network cell with different frequencies and high priority from the plurality of public network cells as the second public network cell according to the neighboring cell configuration information.

The neighboring cell configuration information includes a system information block SIB message, and the step of extracting, as the second public network cell, a public network cell having a different frequency and a high priority from the plurality of public network cells may include:

the network fence equipment analyzes the SIB message and judges whether the SIB message contains the frequency point parameters with different frequencies and high priority;

in the LTE system, system messages are divided into a plurality of MIB messages (Master Information blocks) and a plurality of SIB messages (system Information blocks). In embodiments of the present application, the SIB messages include SIB1 message, SIB2 message, SIB3 message, SIB5 message. And the fence equipment decodes the SIB1 message, and further decodes the SIB2 message, the SIB3 message and the SIB5 message according to the scheduling message in the SIB1 message after contacting the code stream of the SIB1 message. And the fence equipment judges whether the SIB5 message contains the frequency point parameters with different frequencies and high priority.

And if the fence equipment determines that the SIB message contains the frequency point parameters with different frequencies and high priority, determining the public network cell corresponding to the SIB message as a second public network cell. If the fence determines that the SIB message does not contain the frequency point parameters with different frequencies and high priority, the public network cell corresponding to the SIB message cannot be determined as a second public network cell. If the SIB messages broadcast by all the public network cells do not include the frequency point parameters of the pilot frequency and the high priority, then all the public network cells do not include the second public network cell.

Step 204, generating a parameter list by adopting the neighboring cell configuration information of the specific public network cell;

in this embodiment, the specific public network cell only includes the first public network cell and does not include the second public network cell, and in another case, the specific public network cell includes the first public network cell and the second public network cell. After the network fence equipment determines a specific public network cell from the public network cells, the network fence equipment generates a parameter list by adopting the neighbor cell configuration information of the specific public network cell.

In an optional embodiment of the present application, in a case that a specific public network cell is only a first public network cell whose reference signal received power satisfies a first preset condition, the parameter list includes a first parameter list, and the step of generating the parameter list by using the neighboring cell configuration information of the specific public network cell may further include the following substeps:

and a substep S41 of generating the first parameter list by using the neighboring cell configuration information of the first public network cell.

And if the specific public network cell only comprises a first public network cell, generating the first parameter list by adopting the adjacent cell configuration information of the first public network cell. For example, if there are four different-frequency public network cells, namely, cell a, cell B, cell C, and cell D, in the scanned public network cells, and there is no public network cell configured with a high different frequency priority in the four public network cells, the reference signal received powers of the four public network cells are measured, the first three cells of the reference signal received powers are determined as the first public network cell, for example, the first public network cell is determined as cell a, cell B, and cell C, and then the first parameter list is generated by using the neighboring cell configuration information of cell a, cell B, and cell C. In addition, if a plurality of public network cells with the same frequency exist in the cell, the cell with the strongest reference signal receiving power is selected as the first public network cell.

In another optional embodiment of the present application, in a case that a specific public network cell includes a first public network cell whose reference signal received power satisfies a first preset condition and a second public network cell with a pilot frequency and a high priority, the parameter list includes a second parameter list, and the step of generating the parameter list by using the neighboring cell configuration information of the specific public network cell may further include the following substeps:

and a substep S51, generating and establishing the second parameter list by adopting the adjacent cell configuration information of the first public network cell and the adjacent cell configuration information of the second public network cell.

And if the specific public network cell comprises a first public network cell and a second public network cell, generating the second parameter list by adopting the adjacent cell configuration information of the first public network cell and the second public network cell. For example, there are four different-frequency public network cells, cell a, cell B, cell C, and cell D in the scanned public network cells, and there is no public network cell a configured with different frequency and high priority in the four public network cells, the reference signal received powers of the four public network cells are measured, the cell with the strongest reference signal received power is determined as the first public network cell, for example, the cell C is determined as the first public network cell, and then the second parameter list is generated by using the neighboring cell configuration information of the cell a and the cell C.

Step 205, establishing a fence cell according to the parameter list.

After the fence equipment generates the parameter list, the fence cell is established according to the parameter list, if the parameter list has the neighbor cell configuration information of the second public network cell with the pilot frequency and the high priority, the neighbor cell configuration information of the second public network cell with the pilot frequency and the high priority is adopted to establish the first fence cell, the first fence cell is deleted after the preset time is reserved, and then the neighbor cell configuration information of the first public network cell is adopted to establish the second fence cell.

Specifically, the fence cell includes a third fence cell, and the step of establishing, by the network fence device according to the parameter list, a fence cell may include the following sub-steps:

the network fence equipment judges whether the parameter list has neighbor cell configuration information of the second public network cell;

if so, the network fence equipment establishes a first fence cell by adopting the neighboring cell configuration information of a second public network cell;

the network fence equipment deletes a first fence cell after reserving the first fence cell for preset time;

and the network fence equipment establishes a second fence cell by adopting the neighboring cell configuration information of the first public network cell.

In another case, if the parameter list does not have the neighboring cell configuration information of the second public network cell with the pilot frequency and the high priority, the neighboring cell configuration information of the first public network cell is directly adopted to establish the third fence cell.

The step of establishing a fence cell by the network fence device according to the parameter list further includes:

and if the parameter list does not have the neighbor cell configuration information of the first public network cell, the network fence equipment establishes a third fence cell by adopting the neighbor cell configuration information of the first public network cell.

It should be noted that after the fence cell is established by completing configuration information of all neighboring cells in the parameter list once, the station establishment can be stopped, but since the terminals are mobile and have a large number, when a terminal newly enters the coverage area of the fence cell, the capability of continuously and stably acquiring the IMSI of the terminal can be ensured only by continuous polling, and thus, the fence cell can be established by continuous round polling. If the circular polling is selected to establish the fence cell, the circular times are required to be configured in advance, the circular times can be set to be 1 to infinity, if the set circular times are reached, the polling is stopped, the cell is finally established by using the first parameter in the fence cell establishment parameter candidate list, the change period of the tracking area code is set to be N minutes, and when the polling is required again, the circular polling can be triggered again to establish the fence cell.

The target parameters for establishing the fence Cell are a Physical Cell Identifier (PCI) and a public network frequency point parameter. PCI is a wireless signal in LTE by which a terminal distinguishes different cells.

The configuration information of the adjacent cell comprises a physical cell identifier and a public network frequency point parameter, and the network fence equipment establishes a fence cell according to a parameter list, and further comprises the following substeps:

the fence equipment acquires the physical cell identifier and the public network frequency point parameter in the neighbor cell configuration information from the parameter list;

the fence equipment generates fence physical cell identification by adopting the physical cell identification;

optionally, to avoid electromagnetic interference between the fence cell and the original public network cell, a physical cell identifier plus a preset number may be used as the fence physical cell identifier, for example, the physical cell identifier PCI may be added with 4 to obtain the fence physical cell identifier.

And the fence equipment establishes a fence cell by adopting the fence physical cell identifier and the public network frequency point parameter.

After the fence cell is established, the terminal resides in a public network and is in an idle mode, if the same-frequency measurement condition is met, or when the existence of a pilot frequency cell with higher priority is detected, the measurement process of the same-frequency or pilot frequency adjacent cell is started, and when the signal intensity of the adjacent cell meets the reselection condition, the adjacent cell with stronger network signal is accessed.

Step 206, the network fence device communicates with a terminal and receives a connection request sent by the terminal; the connection request is a request sent to the network fence equipment when the terminal detects the fence cell and meets a second preset condition;

and step 207, establishing connection with the terminal by adopting the connection request.

In this embodiment of the application, the second preset condition may be a reselection condition, and when the terminal meets the reselection condition, the terminal sends a connection request to a network fence device, so that the network fence device establishes a connection with the terminal by using the connection request.

Step 208, generating a tracking area code for the fence cell;

in addition, the network fence device generates a TAC (Tracking Area Code) for the fence cell; wherein a tracking area is an area for paging and location update.

The tracking area code comprises a first tracking area code, and the step of generating the tracking area code by the network fence device for the fence cell comprises:

the network fence equipment generates an original tracking area code aiming at the fence cell;

in this embodiment, the network fence device may generate a random number with a preset number of bits as an original tracking area code by using a random number generator for the fence cell.

And the network fence equipment updates the original tracking area code at a preset frequency to generate a first tracking area code.

In order to prevent collision with the tracking area code of the public network cell, the tracking area code of the fence cell established by the network fence device needs to be different from the tracking area code of the public network cell, and if the tracking area code of the fence cell is set to be a fixed value, the tracking area code of the public network cell needs to be measured for many times to configure the tracking area code of the fence cell. In the embodiment of the application, the original tracking area code can be updated through the preset frequency, the first tracking area code is generated, the first tracking area code is a value which is stirred in a range, the fence device does not need to measure the tracking area code of the public network cell for many times, and the preset frequency can be set to be once per second.

Step 209, the network fence device generates an international mobile subscriber identity request message;

step 210, the network fence device sends an international mobile subscriber identity request message and the tracking area code to the terminal;

step 211, the network fence device receives the international mobile subscriber identity sent by the terminal according to the international mobile subscriber identity request message and the tracking area code.

When the Tracking Area code stored in the terminal is inconsistent with the received first Tracking Area code, the terminal initiates a Tracking Area Update (TAU), and after the terminal initiates the TAU, the network fence device replies a TAU reject message to the terminal and updates the Tracking Area all the time, so that the terminal continuously initiates the TAU. In the process, the terminal can report the international mobile subscriber identity to the network fence equipment according to the international mobile subscriber identity request message sent by the base station.

In summary, referring to fig. 5, the network fence device is started or a scanning module in the network fence device scans all information of default configured common frequency points (for example, 75, 100, 1825 of telecommunications), obtains neighboring cell configuration information such as reference signal receiving power, cell identification information, and pilot frequency neighboring cell information of surrounding public network cells by solving a main system information block message and a system information block message of the public network cell, and if there is a neighboring cell with a pilot frequency and a high priority, adds configuration information of the neighboring cell with the pilot frequency and the high priority to a parameter list first, and then selects neighboring cell configuration information of the public network cell with the strongest reference signal receiving power of different frequency points to put the neighboring cell configuration information into the parameter list of the cell. After the network fence device finishes scanning the public network cell, preparing to establish a fence cell, firstly selecting a first parameter in a parameter list, and establishing the fence cell by adopting a default cell parameter, wherein a physical cell identifier of the public network cell plus 4 can be used as a physical cell identifier of the fence cell. And successfully establishing the fence cell or updating the tracking area code once per second, and reselecting the fence cell when a terminal meets the same-frequency measurement and reselection conditions after the fence cell is maintained for one minute, so as to finish the acquisition of the nationality mobile subscriber identification code of the terminal on the frequency point cell. And deleting the fence cell after the fence cell is maintained for one minute, selecting the frequency point of the second parameter of the parameter list to reestablish the fence cell, wherein the cell identification information and other parameters are the same as those of the first time. And after the fence cell is successfully established, updating the tracking cell code at a preset frequency, maintaining for one minute, and reselecting the fence cell after the terminal meets the conditions of same-frequency measurement and reselection so as to complete the acquisition of the nationality mobile subscriber identification code on the frequency point public network cell. And establishing the fence cell by adopting the third parameter of the parameter list, and repeating the process, so that when the polling establishment of the fence cells with different frequency points is completed, the network fence equipment can obtain the international mobile subscriber identification codes of the terminals attached to different public network cells.

In the embodiment of the application, the network fence device obtains a plurality of public network cells through scanning, then obtains the neighbor cell configuration information of the public network cells, then determines a specific public network cell in the public network cells, adopts the neighbor cell configuration information of the specific public network cell to generate a parameter list, and finally establishes the fence cell according to the parameter list, so that the site environment where the network fence device is located is automatically scanned, the proper neighbor cell configuration information is automatically selected, the fence cell is established, and the tedious workload and labor cost caused by establishing the fence cell by a manual reselection scheme are greatly reduced.

In addition, the network fence equipment can sequentially establish a plurality of fence cells with different frequency points according to the parameter list, so that the international mobile subscriber identification codes of terminals residing on the public networks with different frequency points can be automatically acquired under the condition that only one fence equipment is used for covering the public network cells with the plurality of frequency points, the hardware input cost is reduced, and secondly, the tracking area codes can be updated at a preset frequency after the fence cells are established, and the acquisition of the international mobile subscriber identification codes can be completed for multiple times.
