There are many base stations in the mobile communication network, each base station covers a certain geographical area, and establishes a communication connection with the mobile station (MS) or user equipment (UE) moving to its coverage area through the air interface or radio interface, To provide communication services for it. As the UE continues to move, the base station with which it establishes a communication connection is also constantly changing, so that by recording the base station that establishes a communication connection with the UE, a rough estimate of the current geographic location of the UE can be generated, so as to finally achieve the purpose of positioning the UE .

Generally speaking, the accuracy of positioning using a mobile communication network is not high. The use of GPS can achieve more accurate positioning. GPS is a space rendezvous and fixed-point system capable of timing and ranging.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The core idea of the present invention is: by acquiring user location information, generating and storing user displacement records based on the acquired user location information; receiving event information from the outside, and judging whether there is a user displacement record that matches the received event information If it is a displacement record, then send corresponding event information to the user corresponding to the displacement record. Thus, the purpose of providing further information services to users based on the received location information is finally achieved.

The specific details of the location-based information providing method and system of the present invention will be described in detail below in conjunction with the accompanying drawings.

implementation.

First, the location-based information providing method of the present invention mainly includes the following steps:

Step 101: Obtain user location information, generate and store user historical location information records.

Among them, the user location information may specifically include: the time and three-dimensional space information of the user's location point or location area, for example: the three-dimensional coordinate information of the user at a certain moment obtained through GPS, or the establishment of wireless communication with the user in the mobile communication network The connected base station and corresponding time information, or the cell passed by the user and corresponding time information, etc. That is to say, the location point can be a relatively precise two-dimensional area or three-dimensional space area, or an entity associated with the user's location, such as a base station. The time information corresponding to the location point, that is, the usage time includes: the user's entry time and departure time for the location point. Among them, when the location point is a two-dimensional or three-dimensional spatial coordinate, the use time is: the time when the user actually enters the corresponding geographical area and the time when the user leaves. For the base station, it refers to the time when the user starts to establish a connection with the base station and The time of disconnection. In the following description, the time information corresponding to the location point, that is, the time when the user enters the corresponding location point and the time when the user leaves is called the usage time; and the time span during which the user stays at the location point is called the usage duration.

Since the present invention mainly provides information services to users based on the generated real-time location information, there is no limitation on the specific generation method of the user's real-time location information. Therefore, it is only assumed here that the real-time location information of the user has already been generated and can be obtained through a third-party location server or other means. For example: in the system for obtaining historical location information records of users through the mobile communication network shown in FIG. 2, it can be seen that the real-time location information of users obtained through the mobile communication network is stored in the user location server.

Since the user's real-time location information stored in the user location server will be replaced with the change of the user's location, when obtaining the user's location information, you can take the following steps: access the third-party real-time location information storage unit according to the set time interval, as shown in the figure The real-time location information of the user in the user location server shown in 2, when it is determined that the real-time location information for the corresponding user stored therein changes, read the real-time location information of the corresponding user, that is, the corresponding location information after the change, and It is stored to obtain the historical location information record for the corresponding user.

Moreover, in order to obtain the required user location information in a more targeted manner, conditions such as user identification (ID), time range or geographical area can also be set, so as to filter out unnecessary user location information while obtaining user location information. User location information. A specific filtering method may be adopted: judging whether the user identifier of the read user location information matches the target user identifier, and if so, determining that it is the required user location information. In addition, it may further include a time range condition, that is, only obtain the location information of the target user within a certain time period, such as: the location information of user A between 8:00am and 9:00am.

The generated and stored user historical location information records should at least include: location point identification, user identification and use time information items, as shown in Table 1: index User ID location point identification Entry time departure time 1 User A Base station Ba 2005-09-10 08:00 2005-09-10 08:30 2 User A Base station Bb 2005-09-10 08:30 2005-09-10 08:35 3 User A Base station Bc 2005-09-10 08:35 2005-09-10 08:42 4 User A Base station Bd 2005-09-10 08:42 2005-09-10 08:50 5 User A Base station Be 2005-09-10 08:50 2005-09-10 12:30

Table 1

Table 1 is the historical location information records generated for user A in the time period 2005-09-10 08:00 to 2005-09-10 12:30. Wherein, the historical location information record includes information items such as index, user ID, location point ID, entry time and departure time. Wherein, the location point identifier refers to identifying information used to identify the location point of the user, and the identifier may be the name of a representative entity, such as: base station Be, or specific geographical coordinates.

In addition, the present invention can also directly obtain the generated and stored user historical location information from a third-party system, thereby omitting the above-mentioned process of obtaining user real-time location information from a real-time location server and generating historical location information records.

Step 102: Read the stored user historical location information records, generate and store user displacement records based on the read user historical location information records.

Wherein, the user displacement record refers to: the displacement trajectory information passed by the user within a set period of time, and the user displacement record at least includes: constituent nodes, user identification and use time information items. In addition, it may further include: a displacement track identification information item.

The step of generating and saving the user displacement record can be adopted: among the obtained historical location information of the same user, each location point that uses time to connect with each other is used as a constituent node of one or more displacement trajectories, and the corresponding displacement trajectories are established and The storage at least includes: records constituting nodes, user identifiers and usage time information items. And it can also be adopted: when storing historical position information, store it in chronological order, and when generating displacement records, you only need to judge the order of storage to determine whether two position points are adjacent position points, or you can also By setting the previous location information record item in the historical location information record, the judgment of adjacent location points can also be realized. In addition, the present invention may also use other methods to generate displacement records, which will not be listed here.

In the following, the base station establishing a wireless communication connection with the user is taken as the location point, and the historical location information record shown in Table 1 is taken as an example to describe in detail the method of generating the user displacement record.

It can be seen from Table 1 that the time for user A to establish wireless communication connections with base stations Ba, Bb, Bc, Bd, and Be is mutually connected. Therefore, it can be determined that user A establishes wireless communication connections with base stations Ba, Bb, Bc, Bd, and Be in sequence Wireless communication connection, that is to say, user A passes through locations Ba, Bb, Bc, Bd, and Be in sequence, so the base stations Ba, Bb, Bc, Bd, and Be can be used as the constituent nodes of a displacement trajectory of user A. FIG. 3 shows a schematic diagram of a scenario where a base station is used as a location point to generate user displacement records. It can be seen from Figure 3 that user A has established communication connections with 5 base stations during the process of moving from area 1 to area 2, so these 5 base stations can be connected to obtain the approximate displacement trajectory of user A, as shown in The route indicated by the dotted arrow in the figure.

The above is to obtain the displacement track according to the time cohesion of the recorded position points. In addition, on this basis, among the position points where the use time is connected with each other, the two position points whose use time is longer than the set threshold and whose use time is the closest can be used as the end points of a displacement track, and the use time is close to each other. The previous position point is used as the starting point, and the other is used as the end point; then the position point whose use time is less than or equal to the set threshold value and the use time is between the determined use time of the two end points is taken as the middle of the displacement track Finally, these two endpoints and the corresponding intermediate nodes are used as the constituent nodes of the displacement trajectory, so as to obtain a displacement trajectory. Wherein, the usage time includes: the time when the user enters the location point and the time when the user leaves the corresponding location point. The user's usage time is equal to the difference obtained by subtracting the time the user enters the location from the time the user leaves the corresponding location. The following also uses the above examples to describe in detail.

Preset the usage time threshold of user A at a location point as 10 minutes, then the process of generating displacement trajectory according to the location history records in Table 1 is as follows:

Step 1021: As mentioned above, according to the time sequence and time continuity, it can be determined that the user A establishes wireless communication connections with the base stations Ba, Bb, Bc, Bd and Be in sequence. It can be seen from Table 1 that among the five locations, users spend more than 10 minutes at base stations Ba and Be, and user A’s time at base station Ba is earlier than user’s time at base station Be, so base station Ba is used as The starting point of the displacement trajectory.

Step 1022: find out the next base station connected to the base station Ba in time, that is, find out the closest location point between the time of entering and the time of leaving the base station Ba, and determine it as the base station Bb.

Step 1023: Determine whether to continue searching. The specific judgment method is: judge whether the use time of the location point obtained by the user in the previous step 1022 is less than 10 minutes, if yes, continue to search for the next location point, otherwise use the location point obtained in the previous step as the displacement track end point, end this process. In this example, since the user's usage time at the base station Bb is less than 10 minutes, the user will continue to search for the next location point.

Step 1024: Repeat the above steps 1022 and 1023 until the location point with a usage time longer than 10 minutes is found, that is, the base station Be is used as the end point of the displacement trajectory, so that the final displacement trajectory is: Ba-->Bb-->Bc--> Bd-->Be. Moreover, it is also possible to number all the position points constituting the displacement track, such as labeling the base stations Ba, Bb, Bc, Bd and Be as 1, 2, 3, 4 and 5 in sequence, so as to indicate the positions of each location by the order of the labels. The sequence of the location points.

In addition, in order to obtain the user's displacement trajectory information more accurately, the user's actual displacement trajectory can be further obtained based on the obtained approximate displacement trajectory, that is, the route indicated by the solid arrow in FIG. 3 . In specific implementation, it can be taken to compare the obtained approximate displacement trajectory with the actual map of the corresponding geographical area, and determine the most likely actual travel route of the user. In addition, the user's actual travel route can also be obtained by means of a third-party global information system (GIS), by marking the longitude and latitude of the road, or directly approximating the obtained location points.

Of course, the present invention can also adopt other methods to generate displacement tracks, which are not limited here.

The specific method for generating the user displacement trajectory has been described above. Obviously, for a user, there may be many displacement trajectories in a long time range. Therefore, all generated displacement trajectories can be filtered according to the set conditions to obtain one or more displacement trajectories of most concern . For example: within the set time range, the user uses the displacement track with the highest frequency or relatively high frequency. When setting filter conditions, two factors, the track itself and the usage time, can be considered. For example, the judgment of the above-mentioned displacement trajectory with the highest frequency of use can be taken as follows: judge whether the frequency of the user using the displacement trajectory is the highest within the set time range, such as every day or every week, and at the same time judge whether the user uses the displacement trajectory every time. Whether the time of the displacement trajectory is the same or similar, so that this trajectory can be regarded as the regular trajectory of the user. In addition, in terms of route comparison, if the start point and end point are the same, but there are individual differences in the middle position points, it can also be judged according to certain rules whether it is possible to merge routes.

The above describes the generation process of the displacement trajectory. After the displacement trajectory is generated, a record containing at least: constituent nodes, user identification and use time information items is established and stored for the corresponding displacement trajectory. The storage method of the displacement record can be shown in Table 2 below, and the present invention can also adopt other methods to store the displacement track record, which will not be repeated here. Displacement record identification User ID Track ID Constituent nodes Entry time departure time 1 User A Track I Ba, Bb, Bc, Bd, and Be 2005-09-1008:00 2005-09-1012:30 2 User A Track II … … …

Table 2

Step 103: Receive event information from outside, and store the received event information.

Among them, the event information can be various contents related to the stored user displacement records that are preset or customized to a third party, that is, various abnormal situations related to a certain user displacement record, such as: traffic jams, traffic accidents, etc. Moreover, the specific information items included in the event information include: event identifier, location where the event occurred, time of occurrence, event type, and other additional information. In addition, the event information can be set or customized based on one displacement record or location point of the user, or can be set or customized based on multiple displacement records or multiple location points of the user. It should be noted that the event location here has the same meaning as the above location point, that is, it can be a specific geographical area, such as the area affected by the event, or a fixed identifying entity. Such as: base station Ba and so on.

The event information can be stored in a preset event storage unit, and the way of storing the event information can be to store all information items of the received event information, or to store several information items in a targeted manner. For example: the event information storage method shown in Table 3.

index event ID location point area of influence Time of occurrence event type Additional Information 1 event 1 Bd Bc, Be 2005-09-1008:50 traffic jam 2 event 2 … … … …

table 3

Step 104: Read the stored event information and displacement records respectively, and judge whether the read event information and displacement records match, and if so, execute step 105.

Among them, there is a prerequisite that: the event information and the stored displacement records have at least one common information item, such as: location point information item or use time information item, etc.

The step of judging whether there is a displacement record matching the event information includes: using the content in the common information item of the event information as the matching identifier, and judging whether the content in the corresponding information item of the displacement record is related to the matching identifier, if If yes, it is determined that the displacement record matches the event information; otherwise, it is determined that it does not match. In addition, the content in the common information item of the displacement record may also be used as the matching identifier to determine the content in the corresponding information item of the event information, and the description will not be repeated here.

Specifically, when judging, it can be adopted: first traverse the stored event information, and select the contents of one or more common information items contained in it from the currently traversed event information as the matching identifier, then traverse the stored displacement records, and judge Whether there is a displacement record whose content in the corresponding common information item is related to the matching identifier, if so, determine that the event information matches the displacement record; otherwise, continue traversing. For example: if the event information contains the location point information item, the location point can be selected as the matching identifier, and then the displacement record whose location point is the same as or related to the selected location point can be found from all the stored displacement records, as the final match. The event information matches the displacement record. Of course, the present invention can also use other information, such as time, as the matching identifier, which will not be repeated here.

In addition, in the above matching process, in order to provide users with more accurate and valuable information, further matching conditions can be set, such as: based on the above event information and displacement records obtained through matching identification matching, the event information can be further judged Whether the event occurrence time information item of the event matches the time information of the corresponding displacement record, if yes, it is judged as a valid match; otherwise, it is an invalid match.

Moreover, after the matching is successful, the degree of influence of the corresponding event on the user can be further judged, for example: the current location information and the latest historical location information of the user corresponding to the displacement record can be obtained, and then according to the obtained current location information and the latest The historical location information determines whether the corresponding event will affect the user, and if so, executes the step of sending the corresponding event information to the user; otherwise, does not send. The degree of impact can be determined by comprehensively considering the severity and urgency of the event, the user's current location, the track that the user may use soon, and the frequency and time of using the corresponding recorded displacement track.

The above matching method will be described in detail below based on the displacement records shown in Table 2 and the event information records shown in Table 3.

Step 1041: traverse the event information records in Table 3, read event 1, select the affected area information items Bc and Be of event 1 as matching identifiers, and use the occurrence time of event 1——2005-09-1008:50 must be in Use the time range of displacement records as matching criteria.

Step 1042: Traversing the displacement records shown in Table 2, since the position point information items constituting the displacement record 1 include Bc and Be, it can be obtained that the displacement record 1 matches the event 1.

Step 1043: Since the occurrence time of event 1 - 2005-09-10 08:50 is within the time range recorded in displacement record 1 - 2005-09-10 08:00 to 2005-09-10 12:30, Therefore, the time matching condition is met.

In addition, in the above step 1042, when multiple displacement records with the same trajectory but different times are obtained through matching, the earliest entry time and latest departure time among all these displacement records can be taken as the final time range , and then judge whether the occurrence time of event 1 is within the final determined time range. For example: Displacement records 1, 2 and 3 all record the passing track I, and the time range recorded by displacement record 1 is: 2005-09-10 08:00 to 2005-09-10 12:30; the time recorded by displacement record 2 The range is: 2005-09-10 09:00 to 2005-09-10 11:30; the time range of displacement record 3 is: 2005-09-10 7:00 to 2005-09-10 10:30. Therefore, the final determined time range is: 2005-09-10 7:00 to 2005-09-10 12:30, so the event occurrence time should be judged when performing time condition matching—whether it is 2005-09-10 08:50 Within the finalized time range - 2005-09-10 7:00 to 2005-09-10 12:30, it is clear that the event occurred within the finalized time range and thus meets the time match criteria.

Step 1044: Obtain the contained user identification information item from the displacement record 1, that is, user A, and then obtain the current location information of user A from the external user real-time location server, such as: the current location of user A is Bb, and its The current location point Bb is compared with the trajectory I, and it is obtained that Bb is before Bd, so user A may pass through Bd, and may be affected by corresponding events that occur in Bd. In addition, it can be further judged whether the trajectory that user A may currently use is consistent with the historical displacement trajectory to determine the degree of influence of the current event on user A. For example: the latest historical location information of user A can be further obtained from the set historical location information storage unit, and it is obtained as Ba, and through comparison, it is known that the location point Ba is located before the location point Bb on the trajectory I, so it can be further determined Event 1 will affect user A, so it can be further determined that this event will affect this user, so as to improve the accuracy of matching and provide users with high-quality information services.

Step 105: Send event information matching the displacement record to the user corresponding to the displacement record.

Wherein, when the event information is sent to the user, it may be sent according to a pre-subscribed or agreed manner by the user, such as: sending to the user's mobile terminal, fixed terminal or other communication devices. Moreover, the form of sending event information can be adopted: short message, instant message or other voice prompts, etc., and the content of sending event information can also be determined according to the situation, such as: only the event type, affected area, time and location can be sent, or The specific content of the event may be further sent.

The above is the basic structure of the system of the present invention. As shown in FIG. 4, the above-mentioned position information processing unit of the present invention may also include: a position information receiving unit, a position information storage unit, a displacement record generation unit and a displacement record storage unit; wherein, the position The information receiving unit is used to obtain user position information from the outside; the position information storage unit is used to store the position information received by the position information unit; the displacement record generation unit is used to read the stored user position information and generate a user displacement record; the displacement record storage The unit is used to save the generated user displacement records.
