Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. A process may be terminated when its operations are completed, but may have additional steps not included in the figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.
Furthermore, the terms "first," "second," and the like may be used herein to describe various orientations, actions, steps, elements, or the like, but the orientations, actions, steps, or elements are not limited by these terms. These terms are only used to distinguish one direction, action, step or element from another direction, action, step or element. For example, the first feature information may be the second feature information or the third feature information, and similarly, the second feature information and the third feature information may be the first feature information without departing from the scope of the present application. The first characteristic information, the second characteristic information and the third characteristic information are characteristic information of the distributed file system, but are not the same characteristic information. The terms "first", "second", etc. are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "plurality", "batch" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
The terms and abbreviations used in the following examples have the following meanings:
IMSI: the International Mobile Subscriber Identification Number is a mark for distinguishing Mobile subscribers, is stored in the SIM card and can be used for distinguishing effective information of the Mobile subscribers. The IMSI is a unique identifier for distinguishing a mobile subscriber, and other information of the terminal can be obtained if the IMSI of the terminal is obtained, and the IMSI is generally used for detecting and positioning the terminal by government administration departments, public security departments and the like.
PLMN: public Land Mobile Network, the Public Land Mobile Network, which must be interconnected with the Public Switched Telephone Network (PSTN), forms a communications Network of a regional or national scale.
TAC: and Tracking Area Code, wherein the parameter is the identification of a Tracking Area in the PLMN, is used for the position management of the terminal and is unique in the PLMN.
LTE: long Term Evolution, is a Long Term Evolution standard of the universal mobile telecommunications system technology standard, which is between 3G and 4G. It improves and enhances 3G over-the-air access technologies, using OFDM and MIMO as the only standards for their wireless network evolution. The peak rates of 100Mbit/s at the downlink and 50Mbit/s at the uplink are provided under the frequency spectrum bandwidth of 20MHz, the performance of users at the edge of a cell is improved, the cell capacity is improved, and the system delay is reduced.
PCI: physical Cell Identifier, and in LTE, a terminal distinguishes wireless signals of different cells. The LTE system provides 504 PCIs, the concept of the LTE system is similar to that of 128 scrambling codes of the TD-SCDMA system, and when network management is configured, a number between 0 and 503 is configured for a cell. In the LTE cell search procedure, the specific cell ID is determined by retrieving the primary synchronization sequence (PSS, with 3 possibilities), the secondary synchronization sequence (SSS, with 168 possibilities), and a combination of them. The PCI comprises a main synchronization sequence and an auxiliary synchronization sequence, the main synchronization signal is 3 different values of a frequency domain Zadoff-Chu sequence with the length of 62, and the sequence orthogonality of the main synchronization signal is good; the auxiliary synchronization signal is formed by adopting different sequences and 168 combinations for two auxiliary synchronization time slots (0 and 5) in 10ms, the orthogonality of the auxiliary synchronization signal is worse than that of the main synchronization signal, and the main synchronization signal and the auxiliary synchronization signal jointly form 504 PHY _ CELL _ ID codes; the formula is as follows: PCI is PSS +3 SSS, where PSS takes the value 0.. 2 (actually 3 different PSS sequences) and SSS takes the value 0.. 167 (actually 168 different SSS sequences), and the range of PCI that can be obtained using the above formula is from 0.. 503, so there are 504 PCIs in the physical layer. PCI is the downlink cell, and the uplink cell distinguishes E-UTRA cells according to a root sequence, and the search is based on (primary synchronization signals), (secondary synchronization signals) and downlink reference signals to complete the functions of the synchronization signals, such as frequency correction, reference phase, channel estimation and measurement.
Frequency points: the fixed frequencies are numbered. For example, 125 radio frequency bands are divided from 890MHz, 890.2MHz, 890.4MHz, 890.6MHz, 890.8MHz, 891MHz … … 915MHz according to a frequency interval of 200KHz, and each band is numbered from 1, 2, 3, 4 … … 125; these numbers for fixed frequencies are frequency points; in a GSM network, the transmission frequency of a transceiver group is generally specified by replacing the frequency with a frequency point, for example, the frequency point of a carrier is specified to be 3, that is, the carrier will receive an uplink signal with the frequency of 890.4MHz and transmit a signal with the frequency of 935.4 MHz.
And (3) LTE cell reselection: the method refers to a process that a terminal selects a best cell to provide a service signal by monitoring the signal quality of a neighboring cell and a current cell in an idle mode. And when the signal quality and the level of the adjacent cell meet the S criterion and meet a certain reselection judgment criterion, the terminal reselects to the cell to reside. After the UE successfully camps, the measurement of the cell is continuously performed. The RRC layer calculates Srxlev (S criterion) according to the RSRP measurement result, compares the Srxlev with Sintrasearch (same frequency measurement starting threshold) and Snonitrasearch (different frequency/different system measurement starting threshold), and takes the Srxlev as a judgment condition for judging whether to start the neighbor measurement. Sintrasearch: triggering threshold of co-frequency measurement of cell reselection.
Double carrier wave: the dual carrier of a sector means that two carrier frequencies are used by a sector, and the number of users that can be supported depends on the system configuration and the user service type. To take two typical examples, such as GSM, two carrier frequencies can configure 14 TCH, theoretically supporting 14 full rate users to talk simultaneously, or 28 half rate users to talk simultaneously. As another example, TD, the current network configuration is 2: 4, the two R4 carriers can simultaneously support 31 voice users of 12.2k, or 7 video telephony users.
RSRP information: reference Signal Receiving Power, which is one of the key parameters that may represent the wireless Signal strength and the physical layer measurement requirements in an LTE network.
RSRQ information: the Reference Signal Receiving Quality represents the LTE Reference Signal reception Quality, and this metric mainly ranks different LTE candidate cells according to the Signal Quality. This measurement is used as input for handover and cell reselection decisions. Defined as the ratio of N RSRP/(LTE carrier RSSI), where N is the number of Resource Blocks (RBs) of the LTE carrier RSSI measurement bandwidth.
Example one
The present embodiment provides a terminal characteristic acquisition method, which is executed by a terminal performance acquisition device, where the terminal performance acquisition device is configured with two carrier cells, including a first cell and a second cell, and the terminal performance acquisition device mentioned in this embodiment and the following embodiments is described with a 4G single base station as an example. The application range of the embodiment and the following embodiments is a same-frequency networking area, where the networks applicable to the networking area may include wireless networks such as 3G, LTE and 4G, which are described by taking an LTE network as an example.
When the terminal communicates with the base station, the feature acquisition device generates a broadcast signal through a simulation operator network and sends a feature reporting request to the mobile phone to acquire feature information of the mobile phone, wherein the acquired feature refers to IMSI information of the device. As shown in fig. 1, the method for acquiring the terminal characteristics of this embodiment includes the following steps:
s101, sweeping frequency to obtain a current network frequency point with the strongest signal within a preset distance and a current network cell identification code.
The method comprises the steps of obtaining the cell and the frequency point with the highest priority and the strongest SRSP of the existing network environment through frequency sweeping, and obtaining the frequency point of the existing network and the identification code (PCI) of the cell of the existing network.
S102, configuring the first frequency point of the first cell as the current network frequency point, and configuring the first cell identification code of the first cell as the current network cell identification code.
In this step, the first cell of the feature acquisition device is subjected to frequency point self-configuration, so that the first frequency point is consistent with the existing network frequency point, and the first cell identification code is consistent with the existing network cell identification code, so that the terminal identifies the first cell of the feature acquisition device as the current access cell and receives information sent by the first cell.
S103, configuring the second frequency point of the second cell as a neighboring cell frequency point, and configuring the second cell identification code of the second cell as the neighboring cell identification code, wherein the neighboring cell frequency point is different from the current network frequency point.
In the above steps S103-S104, since the common-frequency cell reselection process may occur that the signal of the current network cell is strong, which results in that the common-frequency reselection measurement threshold is not met, the terminal cannot reselect a new cell, which results in that the feature acquisition device cannot acquire the feature information reported by the terminal, the second frequency point of the second cell is configured to be different from the current network frequency point, so that the terminal identifies the second cell of the feature acquisition device as a cell having a frequency different from the current access cell, and the common-frequency cell reselection is changed into a different-frequency cell reselection. In the pilot frequency cell reselection, the characteristic acquisition equipment can enable the terminal to reselect a new cell by setting the priority of the pilot frequency cell to complete the characteristic acquisition.
And S104, sending a system updating signaling to the terminal in the first cell, wherein the system updating signaling comprises the second frequency point and a second cell identification code, so that the terminal is switched from the current access cell to the second cell based on the system updating signaling.
And in the process that the terminal is switched from the current access cell to the second cell, the terminal registers, registers and reports IMSI information to the acquisition equipment, and resides in a new cell again, so that the acquisition equipment acquires the terminal characteristic information.
Before this step, in particular, a first priority of the first cell and a second priority of the second cell are set, where the first priority is lower than the second priority. In this step, specifically, the first priority of the first cell is set to 6, and the second priority of the second cell is set to 7. And sending broadcast information to the terminal in the first cell, wherein the broadcast information comprises the first priority and the second priority.
And S105, acquiring the characteristic information reported after the terminal is switched from the current access cell to a second cell.
The characteristic information in this step refers to information reported by the terminal to the acquisition device based on the system update signaling, and is generally IMSI information of the terminal. The information such as the operator, the user identity, the terminal ID and the like of the terminal can be obtained through the IMSI information of the terminal.
Preferably, as shown in fig. 2, after step S103, the method further includes:
s106, configuring the first terminal tracking area identifier of the first cell to be the same as the second terminal tracking area identifier of the second cell.
The Tracking Area identifier is a Tracking Area Code (hereinafter abbreviated as TAC), and the parameter is an identifier of a Tracking Area in the PLMN network and is used for location management of the terminal. In practical application, the terminal usually marks and/or adds the switched cell into a mark list, and does not perform secondary access to the marked cell. In order to prevent the terminal from repeatedly accessing cell signals released by the acquisition equipment to influence user communication, the acquisition equipment sets the TACs of the first cell and the second cell to be the same TACs, and the TACs are listed in a blacklist after the terminal accesses the TACs once, and are not accessed to the first cell and the second cell in the subsequent communication process.
In the embodiment, the feature acquisition device is used for configuring the first cell and the second cell to simulate the existing network cell and the different-frequency adjacent cell, so that the feature information of the terminal can be acquired in the same-frequency networking environment when the existing network signal is strong, and the communication experience of a user is not influenced.
Example two
On the basis of the foregoing embodiment, this embodiment adds a technical feature of prioritizing signal strength of neighboring cells in a frequency sweeping process, and is executed by a terminal performance acquisition device, where the terminal performance acquisition device includes a first cell and a second cell, as shown in fig. 3, and includes the following steps:

S202, configuring the first frequency point of the first cell as the existing network frequency point, and configuring the first cell identification code of the first cell as the existing network cell identification code.
S2031, sweeping to obtain one or more adjacent cells different from the current network frequency point within a preset distance.
S2032, carrying out priority ranking on the one or more adjacent cells.
In this step, when the terminal performs cell reselection, since there are one or more inter-frequency cells within the preset range, by setting the priority, the cell with the higher priority is more easily selected as the reselected target cell by the terminal.
In the process of prioritization, factors influencing the priority of cell selection include, but are not limited to, signal strength RSRP, signal strength RSRQ, time delay, etc., and also include reselection of cells in different environments (such as high speed or normal) to achieve better resource allocation and service quality.
In this step, specifically, the signal strength of the one or more neighboring cells is first obtained. And then ranking the adjacent cells from strong to weak based on the signal strength information, and taking the adjacent cell with the strongest signal strength as the adjacent cell with the highest priority ranking.

S204, configuring the second frequency point of the second cell as a neighboring cell frequency point, and configuring the second cell identification code of the second cell as the neighboring cell identification code, wherein the neighboring cell frequency point is different from the current network frequency point.
S205, sending a system updating signaling to the terminal in the first cell, wherein the system updating signaling comprises the second frequency point and a second cell identification code, so that the terminal is switched from the current access cell to the second cell based on the system updating signaling.
Optionally, the step specifically includes: and periodically sending system information broadcast in a first cell, wherein the system information broadcast comprises a second frequency point and a second cell identification code of the second cell, so that the terminal starts broadcast search based on the system information update request and acquires the second frequency point and the second cell identification code of the second cell. The terminal registers, registers and reports IMSI information to the acquisition equipment, resides in a second cell, and the acquisition equipment acquires the terminal characteristic information according to the IMSI information.
In this step, the system information update request refers to a downlink sequence generated by the feature acquisition device based on the cell identity (PCI) of the first cell, where the downlink sequence is used to simulate a mobile network operator, so that the terminal detects that the PCI of the resident cell is changed and re-initiates an access procedure. The terminal registers, registers and reports the IMSI information to the collection device, thereby completing the collection of the terminal feature information in step S206.
S206, acquiring the characteristic information reported after the terminal is switched from the current access cell to the second cell.
In an alternative embodiment, as shown in fig. 4, the step S206 includes:
s2061, judging whether the characteristic information is acquired or not.
S2062, if not, acquiring the adjacent cell frequency point and the adjacent cell identification code of the adjacent cell with the second highest priority.
S2063, configuring the second frequency point of the second cell as the adjacent cell frequency point, and configuring the second cell identification code of the second cell as the adjacent cell identification code.
S2064, sending a system update signaling to the terminal in the first cell, where the system update signaling includes the second frequency point and the second cell identification code, so that the terminal is switched from the current access cell to the second cell based on the system update signaling.
And S2065, judging whether the characteristic information of the terminal is acquired.
And S2066, sequentially executing the steps until the characteristic information of the terminal is obtained.
