Description

A method and device for acquiring mobile information

technical field

The invention relates to the field of traffic information, in particular to a technology for acquiring mobile information.

Background technique

With the popularization of cellular terminals, various traffic vehicles carrying cellular terminals spread all over the street network of the whole city. Cellular terminals may include cellular handsets, smartphones, and other wireless devices connected to cellular networks. Correspondingly, more and more attention has been paid to a new theory of using cellular terminals as traffic detectors, which extracts the movement information of these cellular terminals from their mobility management data, and generates traffic information accordingly. The technology applying this theory is also called Cellular Floating Vehicle data (CFVD) technology. Since these mobility management data already exist in the existing cellular network and are easy to obtain, no additional infrastructure is required, and no modification of existing cellular terminals is required, so the popularization and application of CFVD technology is relatively easy and has Big advantage.

The movement information required in traffic applications should usually include a series of positions of the same vehicle at different points in time. Through the CFVD system, mobility information can be extracted from mobility management data with cellular terminals. Mobility management includes two basic types: Dedicated/Active (Active) states related to mobility management, such as switching, initiating a call, or ending a call; Standby/Idle (Idle) related to mobility management Status, such as attach/detach, location area update, routing area update. In the Standby/Idle state, the mobility management of the cellular terminal is at the location area/routing area level; in the Dedicated/Active state, the mobility management of the cellular terminal is at the cell level.

Considering that the dynamic traffic information service is at the street segment/route level, this requires that the spatial distance between two consecutive locations in the mobile information is equivalent to the length of the street segment/route. Moreover, the time interval between the time points of two consecutive locations needs to be comparable to the traffic information update cycle. However, the spatial or temporal distances of the continuous locations extracted from the mobility management data in the Standby/Idle state are much larger than the required scale. Therefore, it is difficult to evaluate dynamic traffic information just by these continuous positions themselves.

In the current CFVD system, the mobility information is usually extracted from the mobility management data of the voice service in the Dedicated state through the interface of the circuit (CircuitSwitch, CS) domain of the GSM/GPRS system. However, considering safety issues, in the near future, the use of voice services during driving is likely to be prohibited, which will greatly reduce the number of samples extracted from voice services in the Dedicated state. Similarly, too short voice call time will greatly reduce the number of extracted samples. Therefore, the application of CFVD system will be seriously affected.

Detailed ways

The technical solutions provided by the various embodiments of the present invention can be applied in the field of traffic information, especially in various traffic-only applications, for example.

FIG. 1 is a schematic flowchart of a method for acquiring mobile information provided by an embodiment of the present invention. The method includes:

Step 101, monitor the quality of traffic samples.

In this embodiment, the traffic samples are various samples used for traffic information applications, including movement information, or may also include other position-related information. Specifically, for example, two consecutive location pairs of the same mobile terminal. The movement information is mainly location information, and may also include other information such as speed information.

In this embodiment, the quality of traffic samples can be evaluated by one or more factors. For example, the quality of traffic samples can be evaluated according to the number of traffic samples on one or more roads; or the quality of traffic samples can also be evaluated by the distance between consecutive locations. The traffic samples and specific factors for evaluating the traffic samples are not limited in this embodiment.

Step 102, when the quality of the traffic sample is lower than the threshold, activate and/or adjust the packet data service of the mobile terminal.

In this embodiment, there are many factors for evaluating traffic samples, and there are also many corresponding thresholds. When the quality of the traffic samples is lower than the threshold, it is necessary to activate and/or adjust the packet data service of the mobile terminal, so that more traffic samples can be obtained to meet the quality requirements of intelligent traffic evaluation.

There are many specific implementation methods for activating the packet data service of the mobile terminal, which can make the mobile terminal change from the Idle state to the Active state, so as to obtain cell-level mobility management data.

In this embodiment, activating the packet data service of the mobile terminal may, for example, send a small amount of trigger information to the mobile terminal, so that the mobile terminal transitions from the Idle state to the Active state and remains in the Active state for a period of time. Thereby, a greater number of traffic samples can be obtained. In this embodiment, the downlink update frequency of the packet data service may also be increased. For example, if the user using the mobile terminal subscribes to a traffic service service, the downlink update frequency of the service may be increased to obtain more traffic samples.

Further, in this embodiment, in order to improve the quality of the traffic samples more effectively and purposefully, and also to affect the packet data service of the terminal as little as possible, activating and/or adjusting the packet data service of the mobile terminal may be, for example, To activate and/or adjust the packet data service of the target mobile terminal.

In this embodiment, there are many ways to limit the affected mobile terminal to the target mobile terminal. For example, it may be restricted by area, a target area is determined, and the target area completely covers or partially covers an area where the traffic sample quality is lower than a threshold, and mobile terminals in the target area are used as target mobile terminals. Further, the state of the mobile terminal in the target area can also be judged, if the mobile terminal is in the Idle state, then the mobile terminal is activated for the packet data service of the mobile terminal; if the mobile terminal is in the Active state, then the packet data service of the mobile terminal is adjusted. Business status, such as increasing update frequency. Further, in this embodiment, a further judgment can be made on the mobile terminal that is already in the activated state. If the packet data service capability of the mobile terminal is weak or there are many services, even if the mobile terminal is located in the target area, it will no longer The packet data service of the mobile terminal is affected, so as to avoid excessive impact on the packet data service of these mobile terminals, thereby affecting user experience.

In this embodiment, the target mobile terminal may also be determined according to the service subscribed by the user of the mobile terminal. For example, if the user signs up for the traffic condition inquiry service or other specific services, the mobile terminal used by the user is used as the target mobile terminal. By identifying the target mobile terminal according to the user's subscription service, the impact on the packet data service of the non-subscription user can be avoided as much as possible. In a specific implementation, the subscription data of the user may be acquired from different network devices, for example, from an HLR (HomeLocationRegister, Home Location Register), or from a VLR (VisitorLocationRegister, Visitor Location Register).

In this embodiment, the target mobile terminal may also be determined in combination with the target area and user subscription data.

Step 103, acquiring mobility management data of the above mobile terminal.

In this embodiment, the mobility management data of the mobile terminal can be acquired from the core network. The access network of the mobile terminal, that is, the corresponding mobile network is, for example, a GSM network, or a WCDMA network, or an LTE network, or a WLAN network, or across the various mobile networks mentioned above. During specific implementation, for different mobile networks, there may be differences in methods for obtaining mobility management data. For example, for a GPRS network, mobility management data can be obtained through the interface between the base station controller and the SGSN. For example, for an LTE network, mobility management data may be acquired through an MME (Mobility Management Entity, mobility management entity).

In this embodiment, in particular, mobility management data in the packet domain is acquired.

Step 104, extracting mobility information from the mobility management data.

In this embodiment, the method for extracting mobility information from mobility management data is the same as the existing method, and will not be repeated here.

Through the method for obtaining movement information provided by this embodiment, when the traffic sample quality is low, the packet data service of the mobile terminal can be affected, thereby improving the traffic sample quality, obtaining movement information, and satisfying various applications in intelligent transportation. Moreover, this technical solution can utilize the mobility management data of the packet domain of the mobile terminal, avoiding the interference of the mobility management data of the circuit domain of the mobile terminal, so that even if the voice service during driving is limited, it will not cause traffic samples The sharp decline in quality ensures the need to obtain a large number of high-quality mobile information.

As shown in FIG. 2 , the embodiment of the present invention provides a specific method for acquiring mobile information. The method includes:

Step 201, judging whether the number of traffic samples on the selected road segment/area is lower than a threshold, and if so, go to step 202.

In this embodiment, there may be one or more selected road sections/areas. After comparing with the threshold, if it is not lower than the threshold, the selected road section/area can be continuously monitored, or the next selected road section/area can also be judged.

Step 202, determine the target area.

In this embodiment, the target area completely covers the road segment/area selected in step 201 . During specific implementation, the target area is, for example, a collection of multiple cells or location areas or routing areas.

Step 203, acquiring user subscription data.

In this embodiment, for example, the subscription data of users who subscribe to the traffic real-time road condition service may be acquired. Further, in order to reduce the amount of data transmission and acquisition, it may be limited to only acquire subscription data of users in the target area. For example, the user's subscription data can be obtained through the HLR.

Step 204, determine the target mobile terminal.

In this embodiment, for example, a mobile terminal used by a user who subscribes to the traffic real-time road condition service located in the target area may be used as the target mobile terminal.

Step 205, activate and/or adjust the packet data service of the target mobile terminal.

Referring to the embodiment shown in FIG. 1 , the packet data service of the target mobile terminal can be activated or adjusted according to different situations to obtain mobility management data with a smaller granularity and a larger quantity.

Step 206, acquiring mobility management data of the target mobile terminal in the packet domain.

In this embodiment, for example, the mobility management data of the packet domain is obtained through the SGSN.

Step 207, extract mobility information from the mobility management data.

Through the method for obtaining mobile information provided by the embodiment of the present invention, the mobility management data in the packet domain can be used to obtain mobile information to meet the requirements of intelligent transportation applications. Moreover, it can provide a large number of traffic samples with high quality, thereby ensuring the stability and reliability of the application. At the same time, the method provided by the embodiment of the present invention can also reduce the dependence of mobile information on CS domain mobility management data, so that when the CS domain mobility management data is greatly reduced, the impact on the acquisition of traffic samples is reduced, ensuring intelligent transportation Applications.
