Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a system for acquiring user location information, and a call receiving device.
Background
The wireless communication network is characterized by the mobility of users, and thus the service requirement for the position information of the users is derived. In recent years, various positioning technologies have been developed rapidly, taking Code Division Multiple Access (CDMA) network as an example, positioning of a terminal can be achieved by integrating a positioning function of satellite navigation and a function of triangulation positioning into a CDMA terminal chip, so that the terminal has a capability of high-precision positioning (with an error of 5-50 meters). Positioning requirements in emergency services have also been proposed earlier, and as early as 1996, the Federal Communications Commission (FCC) of the united states mandates that all wireless service providers must provide location information and terminal numbers of users to a public safety service system when a mobile user triggers an emergency call in order to perform emergency rescue work on the user, and such a service that acquires location information of the originator user at the same time as the emergency call is called E911.
Currently, the E911 and other various positioning applications are concerned with obtaining the position information and terminal information of the positioned user. Taking E911 as an example, the networking and service implementation process thereof is described briefly.
Fig. 1 is a schematic diagram illustrating networking of an emergency call service in the prior art, which includes a Mobile Switching Center (MSC) 1 for providing a wireless connection to a user; a Mobile Positioning Center (MPC) 2 for checking whether a user initiating positioning has the right to perform positioning after receiving a positioning request, and selecting a suitable Positioning Determining Entity (PDE) 3 to perform positioning on the user; PDE3, which is used to calculate the final position (including longitude, latitude, altitude, etc.) of the user through the original parameters returned by the user; one MPC2 may be connected to multiple PDEs 3, and multiple PDEs 3 may use one or different positioning techniques; a Coordinate Routing Database (CRDB) 4, configured to convert between a known Coordinate position and a corresponding Emergency service area name, where, for example, when the longitude is X and the latitude is Y, the corresponding area name is north huaqiang, and an Emergency service Routing number (ESRD) corresponding to the Emergency service area is stored in the CRDB 4; a Public Safety answering station (PSAP) 5 for answering the user-initiated emergency call.
Location of emergency calls supports two ways of communicating location information of an emergency call user equipment: namely, a PUSH (PUSH) mode for transferring location information in call setup information and a PULL (PUSH) mode for acquiring an initial or updated location using non-call related information, the PUSH mode being a mode for acquiring location information of a user to a network when needed by an emergency service provider in an emergency call service, and being a mode for transferring location information of a user who initiated an emergency call, which is commonly used in the emergency call service.
As shown in fig. 2, a flowchart of signaling for acquiring user location information in a PULL manner in the prior art specifically includes the following steps:
step 101, a Mobile terminal (Mobile Station, hereinafter referred to as MS) initiates an emergency call;
step 102, after detecting an emergency call, the MSC initiates a call establishment request to an Emergency Services Network Entity (ESNE), where the ESNE is a general routing Router (S/R), and the MSC also carries ESRD information when initiating a call establishment to the ESNE;
step 103, the call setup request is routed to the PSAP;
step 104, the PSAP sends request information to the MPC through an emergency services Message Entity (ESME for short) as required to request the location of the user corresponding to the emergency call;
105, the MPC sends a positioning request message to the PDE to request the latest position of the MS;
106, the PDE interacts with the MS through the MSC, and the position information of the MS is obtained through calculation;
step 107, sending the position information of the MS to the MPC;
step 108, the MPC searches the CRDB according to the location information to obtain the area name corresponding to the location information;
step 109 returns the location information to the PSAP via the MPC.
In the above technical solutions, only the user who initiates the emergency call is located, and the location information of the user around the user cannot be acquired, which brings certain difficulties to rescue, case investigation after the fact, and the like.

Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.
The scheme of the embodiment of the invention is that the position information of the users in the same cell is determined by providing the user equipment information of the emergency users and the users in the same cell for a positioning network, and the users in the same cell are positioned, wherein the emergency users are users initiating emergency calls, and the users in the same cell are other users, except the emergency users, in the same cell with the emergency users.
As shown in fig. 3, a schematic flow chart of a first embodiment of a method for acquiring user location information according to the present invention is shown, and the method includes the following steps:
the call receiving equipment can be a public safety answering station (PSAP), and the received user equipment information at least comprises identification information of an emergency user and a co-cell user, and can also comprise call state information of each user equipment or other necessary information;
when sending a positioning request, the call receiving equipment needs to carry user equipment information of an emergency user and a user in the same cell, namely identity identifications of the emergency user and the user in the same cell, so as to request to position the emergency user and the user in the same cell;
the positioning network calculates the position of the user equipment initiating the emergency call and other user equipment of the cell according to the user equipment information of the emergency user and the user equipment information of the user in the same cell carried in the received positioning request;
the call receiving equipment receives the position information returned by the positioning network, and can acquire the position, the call state and the like of the user in the same cell close to the emergency user, so as to assist the user initiating the emergency call when necessary.
In this embodiment, the location of the user initiating the emergency call and the user in the same cell is realized by obtaining the user equipment information of the emergency user and the user in the same cell, and determining the location information of the user initiating the emergency call and the location information of other users in the cell where the user initiates the emergency call according to the user equipment information. By knowing the position of the user in the same cell close to the emergency user, the user who initiates the emergency call can be timely and effectively rescued.
As shown in fig. 4, a signaling flowchart of a second embodiment of the method for acquiring user location information of the present invention includes the following steps:
the user equipment information at least comprises identity identification information of an emergency user and a user in the same cell, and can also comprise call state information of each user equipment or other necessary information;
305, after receiving the emergency call, the PSAP sends positioning request information to a mobile positioning center MPC according to the user equipment information of the emergency user and the user equipment information of the user in the same cell;
step 308 may also be that the MPC returns the received location information to the MSC first, and then the MSC sends the location information to the PSAP.
After the PSAP receives the position information of the emergency user and the user in the same cell obtained by the calculation of the PDE, the PSAP can further screen the position information of the user in the same cell because the PSAP obtains too much position information of the user equipment in the same cell and some position information of the user equipment in the same cell is possibly close to the emergency user, and finally screen other users in the same cell which are considered to be close to the user initiating the emergency call so as to quickly and effectively rescue the user equipment initiating the emergency call.
At the PSAP, the location information of the users in the same cell is further filtered, as shown in fig. 5, the filtering steps are as follows:
and step 403, comparing the distance between the emergency user and each user of the users in the same cell with the radius of the screening area, and screening the users in the same cell, of which the distance from the emergency user is smaller than the radius of the screening area, from the users in the same cell.
That is, the position information of the emergency user and the position information of the user in the same cell calculated by the PDE are sent to the PSAP; PSAP calculates the distance between the emergency user and each user of the same cell; setting the radius of a screening area on a PSAP; and comparing the radius of the screening area with the distance between the emergency user and each user of the same cell user, and screening out the users in the same cell user suitable for emergency rescue.
The screening method has the advantages that: the area radius of the cell where the emergency call user equipment is located can be set in a targeted and flexible manner aiming at the individual case of initiating the emergency call user equipment each time, and the area radius can be set to be relatively smaller in places with large population density.
As shown in fig. 6, a schematic flow chart of a third embodiment of the method for acquiring user location information in the present invention includes the following steps:
the user equipment information at least comprises identity identification information of the same-cell user of the emergency user, and also can comprise call state information of each user equipment or other necessary information;
step 504, MSC routes the emergency call carrying the received user equipment information of the user in the same cell to PSAP;
step 505, after receiving the emergency call, the PSAP sends a positioning request message to a mobile positioning center MPC according to the user equipment information of the emergency user and the user equipment information of the user in the same cell;
user equipment information of an emergency user and user equipment information of a user in the same cell are carried in a positioning request sent by a PSAP;
step 506, after receiving the positioning request information, the MPC sends a location information acquisition request carrying the ue information of the emergency user and the ue information of the user in the same cell to the PDE;
step 507, the PDE receives the location information acquisition request, extracts the user equipment information of the emergency user and the user equipment information of the user in the same cell in the location information acquisition request, and calculates the location information of the user equipment of the emergency user and the user in the same cell;
step 508, PDE obtains the radius of the screening area of the emergency user;
in this embodiment, the PDE screens the location information of all other ue obtained by calculation, and first obtains a radius of a screened area, where the radius of the area can be obtained through the following two ways: firstly, acquiring from MSC, setting the radius of the screening area by MSC when configuring the cell, wherein the MSC needs to increase the setting and storage functions of the radius of the screening area, and increases an interface between the MSC and the MPC for transmitting the set radius of the screening area to the PDE; acquiring from the coordinate routing database CRDB, setting the radius of the area to be screened of the cell where the corresponding emergency call user equipment is located in the CRDB when each emergency service area is defined, and also needing the CRDB to increase the setting and storing functions of the radius of the screened area and increase the interface between the CRDB and the MPC for transmitting the radius of the area to the PDE.
Step 509, calculating the distance between the emergency user and each user of the users in the same cell;
and step 510, comparing the radius of the screening area with the calculated distance between the emergency user and each user of the users in the same cell, screening the users in the same cell with the distance smaller than the radius of the screening area, and determining the users in the same cell as the users suitable for emergency rescue.
Step 511, the PDE submits the screening result and the calculated position information to the MPC, and the screening result and the position information are returned to the PSAP via the MPC;
step 511 may also be that the MPC returns the received screening result and location information to the MSC first, and then the MSC sends the screening result and location information to the PSAP. The screening result at least comprises user equipment information of which the distance between the cell users and the emergency users is less than the radius of the screening area.
In the embodiment, the users in the same cell are screened out by screening the users in the same cell in the PDE, so that the users in the same cell which are close to the emergency user can be associated with the users in the shortest and most convenient way, and the emergency user can be rescued quickly and effectively.
