Description

Statistical method and device for network resident user related information

The present invention relates to a data collection and evaluation technique for a mobile communication system, and more particularly to a statistical method and apparatus for network-resident user-related information. Background technique

In the mobile communication market, the competition between operators is very fierce. Who can attract more users, provide better user experience, and who can get the most benefit. Therefore, it is very necessary for the operator to understand the number of users and user terminal-related information that actually resides in a specified area of the network (such as by cell, location area, etc.), or even the entire network, and because of the user's resident behavior. Diversity, such as long-term shutdown of the user, no service in standby, dual-mode single-standby terminal automatic or forced selection of better quality network, regional mobility, etc., bring more uncertainty to the resident network information in the statistical network. Due to the existence of these factors, some methods of resident users in the statistical network, such as manual sampling statistics or by querying users registered in the core network, are difficult to obtain more accurate and multi-dimensional statistical results.

How can we eliminate these uncertainties and effectively count the situation of network-resident users? We can take advantage of the location update (or routing area update) process between the user and the network, combined with the user log records of the network collection.

Location update (or routing area update) is a common process for the network to obtain terminal location information. Taking location update as an example, there are three main categories: normal location update (over location location location update), international mobile subscriber identity (IMSI, International Mobile Subscriber Identity ) Attached location updates (when the user is powered on), and periodic location updates (cycle T3212, specified by the network side). The periodic location update is to solve the problem in some cases (for example, because the quality of the wireless link is poor, the network cannot receive the correct message of the terminal, and the terminal is still powered on at this time) Status and receiving messages from the network) A mandatory registration measure that the network cannot know about the state of the mobile station requires the mobile subscriber to register once per specific period of time. In this way, as long as the user is in the power-on state, various types of location update processes establish a relationship between the network resident user and the network, and thus can be used for statistics of the network resident users. Summary of the invention

FIG. 3 is a schematic structural diagram of a statistical device for information related to a network resident user according to the present invention. detailed description

The technical solutions of the present invention are further elaborated below in conjunction with the accompanying drawings and specific embodiments. The statistical method for network-resident user-related information provided by the present invention is applicable to mobile communication networks of various standards, such as GSM, TD-SCDMA, WCDMA, CDMA2000, LTE, and the like. In the present invention, a TD-SCDMA system network is taken as an example to describe a statistical method for network-resident user related information.

As shown in FIG. 1 , the statistical method for the network to hold user related information in the network mainly includes the following steps:

Step 101: When the user initiates a call, the radio network controller (RNC, Radio NetWork Controller) generates a user log record corresponding to the current call; and when the call is normal or abnormally ended, the RNC outputs the user log record.

It can be seen that each time a user initiates a call to an end call, the RNC outputs a user log record for the call process; and, for a user, the information about the user recorded in each user log record. (that is, information about resident users) may be different. In the 3G network, the UE initiates a call, and initiates a Radio Resource Control (RRC) connection request to the network side.

In the present invention, the resident user related information recorded in the user log record includes: a location area code (LAC, Location Area Code) and a routing area code (RAC, Route Area Code) at the time of the call access, and a cell at the time of the call. Identification, call origination time, cell identity at the end of the call, end call time, and user identification;

The location area code and the routing area code of the current access are carried in the first initial direct transmission message of the domain after the UE establishes an RRC connection with the wireless network.

The cell identity at the time of the call is the identity of the cell where the UE is located when the RRC connection is initiated; the cell identity at the end of the call is the identity of the cell where the UE is located when the call is terminated; the purpose of recording the location area, the routing area, and the cell is Enable statistical algorithms to output user-related information by region.

The user identity generally includes: a user phone number, and an International Mobile Subscriber Identity (IMSI), an International Mobile Identity (IMEI), and a Radio Network Temporary Identity (U-RNTI), and a Cell Radio Network Temporary Identity (C-RNTI). And a packet domain temporary identity code (P-TMSI) and a temporary identity code (TMSI); wherein, for P-TMSI and TMSI, the user identity may also include either;

The originating time is the time when the network receives the RRC connection request initiated by the UE;

The end of the call is the moment when the network ends the call.

Step 102: Analyze user log records collected by the entire network RNC on the network side, and record the resident user related information into the resident user table according to the user log record.

In the present invention, the user log record of the entire network can be analyzed on the network side through the signaling monitoring and analysis system.

When analyzing the user log records of the entire network, the algorithm used is as shown in Figure 2: First, set the statistical time period T1 of the information about the resident users. For example, you can refer to the user line. For the factor, select 8: 00-20: 00 of the working day as the statistical time period T1;

Second, set the statistical time interval T2, which is an integer multiple of T2. The setting of T2 needs to consider the period of periodic location update or periodic routing area update, so that the user can initiate a periodic location update or periodic routing area update in T2. The T3212 is a periodic location update timer, and the T3312 is a periodic routing area update timer. If the duration of the two timers is larger, it is recorded as Tp. Therefore, the value range of Τ2 can be set to Τρ<Τ2< 2Τρ, such as 1.5Τρ.

Then, based on the statistical time period T1 and the statistical time interval Τ2, the user log records of the entire network are analyzed, and the resident user related information is recorded into a resident user table. Preferably, a Τ2 correspondence can be set. A resident user table (specifically, illustrated by the following embodiments) may also store the resident user information of the entire network into a resident user table, but classify the resident user table according to Τ2, The resident user tables corresponding to multiple Τ2s are combined into one resident user table. It should be noted that, in the present invention, the user identity + cell identity (cell identity at the time of call initiation, or cell identity at the time of ending the call) is required as the joint key information, and the duplicate resident user related information is prevented from being recorded.

Specifically, the analysis of the user log record and the record of the resident user related information are as follows: 起 The call start time and the end call time of the user recorded in a certain user log record are respectively Ts and Te.

First, it is determined whether Ts is within T2, that is, whether the starting time Ts of the user's call occurs in T1, and if so, it is necessary to determine which T2 the Ts falls in; if not, the user log is not required. Record the related information of the recorded resident users for statistics.

If Ts falls within T2, traverse the resident user table corresponding to the T2, check whether the same user identifier and the cell identifier at the time of the call are recorded, if the same user identifier is not found (indicating that the table does not record the same) Any relevant information of the user), or find the same user identity but the calling cell identity is different (indicating that the relevant information corresponding to other calls of the user is recorded in the table, and If the call corresponding to the previous Ts is different, the information about the resident user corresponding to the current call of the user is filled in the resident user table corresponding to the T2. Specifically, the related information about the retained user includes: the user identifier, the LAC, RAC, and cell identity (including the cell identity at the time of the call and the d, zone identifier when the call is terminated);

If the same user identifier and the cell identifier at the time of the call are recorded in the resident user table corresponding to the T2, the resident user related information corresponding to the current call of the user is not recorded; and then, it is determined whether the Te falls within the T2;

If Te falls within T2, it traverses the resident user table corresponding to the T2, checks whether the same user identifier is recorded and the cell identifier at the end of the call, if the same user identifier is not found (indicating that the table does not record the Any relevant information of the user), or find the same user identity but the cell identity is different when the call is terminated (indicating that the related information corresponding to other calls of the user is recorded in the table, which is different from the call corresponding to the current Te), then the user is The information about the resident user corresponding to the call is filled in the resident user table corresponding to the T2. Specifically, the related information about the retained user includes: the user identifier, the LAC, the RAC, and the cell identifier (including the cell identifier at the time of the call) And the cell identifier when the call is terminated; if the same user identifier and the cell identifier at the end of the call are recorded in the resident user table corresponding to the T2, the resident user related information corresponding to the user's current call is not recorded.

Embodiment 1 As shown in FIG. 2, in a user log record of user A, the user's call from Tsl time to Tel time first determines that Tsl falls within T2 ( 2 ), then traverses T2 ( 2 ) The corresponding resident user table is used to check whether the same user identifier and the cell identifier at the time of the call are recorded.

As shown in Table 1, the resident user information recorded by the resident user table corresponding to T2 ( 2 ):

Table 1 It is assumed that the cell identifier recorded in the user log record of user A is 01, and the same user identifier and the same cell identifier as the cell identifier at the time of the call are recorded in Table 1, so that the user is not required to be recorded in Table 1 for the time being. The resident user information corresponding to the secondary call; then it is determined that the Tel also falls within T2 ( 2 ), and then traverses the resident user table corresponding to Τ 2 ( 2 ) again to check whether the same user identifier and the ending call are recorded therein. If the cell identifier is the same as the cell ID in the user log record of the user Α, the cell ID is 01 (the cell does not change during the call), and the user is not required to record the user in Table 1. Calling the corresponding resident user related information; 4) If the cell ID is 02 when the end call is recorded in the user log record of user A (the cell changes during the call), the user needs to be added in Table 1. Corresponding resident user related information, as shown in Table 2:

Table 2

It can be seen that for the user log of [Tsl, Tel], if the cell does not change during the call, a resident user table record is generated in the T2 (2) statistical interval, and if the cell changes, it is generated. Two resident user table records.

Embodiment 2 As shown in FIG. 2, in a user log record of user B, the user's call from Ts2 to Te2 first determines that Ts2 falls within T2 (3), and traverses T2 (3). The corresponding resident user table is used to check whether the same user identifier and the cell identifier at the time of the call are recorded.

As shown in Table 3, the resident user information recorded by the resident user table corresponding to T2 ( 2 ):

table 3 Assume that the cell ID of the caller in the user log record of the user B is 03, and the same user ID and the same cell identity as the cell ID at the time of the call are recorded in Table 3, so that it is not necessary to record in Table 3 temporarily. User B corresponds to the resident user-related information of this call; then determines that Te2 falls within T2 ( 4 ), then traverses the resident user table corresponding to T2 ( 4 ), assuming that the end recorded in user B's user log record When the cell ID of the call is 03, but the same user ID is not recorded in the resident user table corresponding to T2 (4), or the same user ID and different cell identifier are recorded, the resident corresponding to T2 (4) is required. The user table records the information about the resident user corresponding to the call of User B, as shown in Table 4:

Table 4

It can be seen that for the user log of [Ts2, Te2], since the two statistical time intervals T2 are spanned, a resident user table record is generated in each of the T2 (3) and T2 (4) statistical time intervals.

When analyzing the user log records of the entire network, if it is found that no user's Ts falls within the T2 statistical interval, the resident user table record corresponding to T2 is completed. Once the resident user table record is complete, step 103 is performed.

Step 103: Perform multi-dimensional analysis on the information about the resident user according to the entire network, the location area, the routing area, the cell, the terminal type, and/or the time period based on the resident user table, and output a statistical result of the information related to the resident user.

For example, the resident user table itself reflects all the resident users of the entire network in T2 (that is, the analysis of the related information of the resident users by time period); on the basis of analyzing the information about the resident users by time period, The LAC, the RAC, and/or the cell identifier are keywords, and the same user is removed according to the user identifier, and statistics about the resident user according to the location area, the routing area, and/or the cell are obtained; on this basis, the user may also be The IMEI information in the identifier distinguishes different user terminals Type, further obtaining the resident status of various terminal types in the network. In addition, the data of each statistical time interval T2 can be aggregated and analyzed, and the average trend of the network resident users in the statistical time period T1 can be obtained.

Certainly, the resident user related information may be counted according to any one or several angles of the entire network, the location area, the routing area, the cell, the terminal type, and the time period, and the statistical result is obtained.

According to the statistical algorithm of the present invention, the statistical algorithm of the logbook of the entire network is used to classify statistics from various dimensions in a certain statistical period to obtain related information of the network resident users. It provides a reference for operators to understand the network operation status and reasonably carry out network layout.

Determining that the same user ID and the same are recorded in the resident user table as in the user log record The data recording module 20 is further configured to: determine whether the end call time (Te) in the user log record falls within a certain T2, and if so, traverse the resident user table corresponding to T2, determine to reside. If the same user ID in the user log record is not recorded in the user table, or the same user ID as in the user log record and the cell ID at the end of the call are recorded, the information about the resident user in the user log record is recorded to The resident user table corresponding to T2.
