一种移动通信搜索定位方法、装置和存储介质A mobile communication search and location method, device and storage medium

技术领域technical field

本申请涉及无线通信技术领域，尤其涉及一种移动通信搜索定位方法、装置和存储介质。The present application relates to the technical field of wireless communication, and in particular to a mobile communication search and location method, device and storage medium.

背景技术Background technique

搜索定位设备是基于无线通信基站技术的原理，通过模拟运营商的移动通信网络(移动/联通/电信/广电)的广播诱导信号，提供比公网基站更强的信号，使得周围处于待机状态的手机或终端检测到位置区发生变化，从而发起位置区更新流程，向搜索定位设备进行注册、上报IMEI/IMSI(4G)或SUPI/SUCI(5G)，以此完成对覆盖区域内的公网用户终端信息采集，然后通过有线或无线回传的方式将采集到的IMEI/IMSI或SUPI/SUCI实时传输到后台数据管理系统中心，用户可以通过客户端软件和后台管理系统连接到采集中心实时查看到采集的移动终端的信息，可以广泛应用于野外/沙漠/海上应急救援场景中。The search and positioning equipment is based on the principle of wireless communication base station technology. By simulating the broadcast induction signal of the operator's mobile communication network (China Mobile/China Unicom/Telecom/Radio and Television), it provides a stronger signal than the public network base station, so that the surrounding area is in a standby state. The mobile phone or terminal detects that the location area changes, thereby initiating the location area update process, registering with the search and positioning device, and reporting the IMEI/IMSI (4G) or SUPI/SUCI (5G), so as to complete the public network user within the coverage area The terminal information is collected, and then the collected IMEI/IMSI or SUPI/SUCI is transmitted to the background data management system center in real time through wired or wireless backhaul. Users can connect to the collection center through the client software and the background management system to view it in real time The collected information of the mobile terminal can be widely used in field/desert/marine emergency rescue scenarios.

一般来说，在已知待定位的设备处于某个区域后，搜索定位设备即可针对待定位的设备进行搜索，但由于终端检测到位置区发生变化的前提为处于待机状态，因此，若是待定位的设备处于通话状态下，是无法实现对其搜索和定位的。Generally speaking, after the device to be located is known to be in a certain area, the search and location device can search for the device to be located. When the device is in a call state, it is impossible to search and locate it.

如何针对处于通话状态下的设备的搜索和定位是一个亟需解决的问题。How to search and locate a device in a call state is an urgent problem to be solved.

FIG. 2 is a schematic flowchart of a mobile communication search and location method provided in an embodiment of the present application. The mobile communication search and location method can be implemented based on the schematic diagram of the system architecture shown in FIG. 1, and can also be implemented based on other architectures. The executor of the mobile communication search and location method is the above-mentioned search and location device in this embodiment. The method includes but is not limited to the following steps:

步骤S201：获取位于目标区域的待定位的目标用户的手机号的国际移动用户识别码IMSI。Step S201: Obtain the International Mobile Subscriber Identity IMSI of the mobile phone number of the target user to be located located in the target area.

在获取IMSI之前，首先通过视觉、地理围栏等手段先初步确定出所述目标用户处于目标区域且逗留时长超过预设时长，该目标区域范围相对较大，且目标用户的手机号无法准确获悉，需要搜索定位设备吸附目标用户设备。Before obtaining the IMSI, it is first preliminarily determined that the target user is in the target area and stays longer than the preset time by means of vision and geo-fencing. The target area is relatively large, and the mobile phone number of the target user cannot be accurately obtained. It is necessary to search and locate the device to absorb the target user device.

所述搜索定位设备根据后台管理系统确定位于目标区域的待定位的目标用户的手机号的IMSI。The search and location device determines the IMSI of the mobile phone number of the target user to be located in the target area according to the background management system.

所述后台管理系统可通过与运营商服务器或相关部门后台服务器交互，获取上述的IMSI。The background management system can acquire the above-mentioned IMSI by interacting with the operator's server or the background server of the relevant department.

步骤S202：向信号覆盖目标区域的多个运营商服务器发送针对所述目标用户的IMSI的状态查询请求。Step S202: Send a status inquiry request for the IMSI of the target user to servers of multiple operators whose signals cover the target area.

所述信号覆盖目标区域的多个运营商服务器指的是任一终端在目标区域内可以连接的运营商服务器。The multiple operator servers whose signals cover the target area refer to the operator servers that any terminal can connect to in the target area.

步骤S203：接收来自所述运营商服务器的响应消息。Step S203: Receive a response message from the operator server.

所述响应消息包括目标用户设备的业务状态的目标响应消息。The response message includes a target response message of the service state of the target user equipment.

由于IMSI仅归属于某一运营商，因此与所述IMSI对应的运营商服务器会向所述搜索定位设备返回携带有目标用户设备的业务状态的目标响应消息；而对于与所述IMSI不对应的运营商服务器会针对性的返回内容为空或结果未知的响应消息。Since the IMSI only belongs to a certain operator, the operator server corresponding to the IMSI will return a target response message carrying the service status of the target user equipment to the search and location device; The operator's server will return a response message with empty content or unknown result.

步骤S204：根据所述目标用户设备的业务状态的目标响应消息，确定所述目标用户设备的业务状态是否为处于通话中。Step S204: According to the target response message of the service state of the target user equipment, determine whether the service state of the target user equipment is in a call.

若目标用户设备的业务状态为未处于通话中，则直接根据目标运营商所属的参考频段范围、和本地预存的空频点集合，确定空频点集合中处于参考频段范围的至少一个候选空频点；进一步的，在候选空频点广播诱导信号，提供比公网基站更强的信号，使得周围处于待机状态的手机检测到位置区发生变化，从而发起位置区更新流程，向侦码设备进行注册、上报IMSI，完成对覆盖区域内的公网手机信息采集，然后将采集到的IMSI实时传输到后台管理系统，直至找到所述目标用户设备的IMSI；并缓存当前侦码处理周期吸附到参考用户设备的小区频点和物理小区标识PCI。If the service state of the target user equipment is not in a call, then directly determine at least one candidate space frequency within the reference frequency band range in the space frequency point set according to the reference frequency band range to which the target operator belongs and the locally pre-stored space frequency point set point; further, the induction signal is broadcast at the candidate space frequency point, which provides a stronger signal than the public network base station, so that the surrounding mobile phones in the standby state detect the change of the location area, thereby initiating the location area update process and sending the code to the detection device. Register and report IMSI, complete the collection of public network mobile phone information in the coverage area, and then transmit the collected IMSI to the background management system in real time until the IMSI of the target user device is found; and cache the current code detection processing cycle and absorb it to the reference The cell frequency point and physical cell identity PCI of the user equipment.

步骤S205：若所述目标用户设备的业务状态为处于通话中，则确定所述目标用户设备的通话事件类型。Step S205: If the service state of the target user equipment is in a call, determine the call event type of the target user equipment.

具体的，设备处于通话状态下可分为两种情况，情况一为通过终端直接拨打电话进行通话；情况二为通过网络拨号或手机应用进行通话，例如微信电话。Specifically, when the device is in a call state, it can be divided into two situations. The first situation is to directly dial a phone through the terminal to make a call; the second situation is to make a call through network dialing or a mobile application, such as a WeChat call.

情况一对应的是非互联网类电话业务即走电话域，情况二对应的是互联网类电话业务即走数据域。Case 1 corresponds to the non-Internet telephony service, that is, the outgoing phone domain, and Case 2, that corresponds to the Internet telephony service, that is, the data domain.

步骤S206：根据所述目标用户设备的通话事件类型，确定能够吸附所述目标用户设备的参考频段范围。Step S206: According to the call event type of the target user equipment, determine a reference frequency range capable of absorbing the target user equipment.

若所述通话事件类型为非互联网类电话业务即走电话域；在一种可选的实施方式中，确定能够吸附所述目标用户设备的参考频段范围的过程如下所示：If the type of the call event is a non-Internet telephony service, that is, the go-go domain; in an optional implementation manner, the process of determining the range of the reference frequency band capable of absorbing the target user equipment is as follows:

确定所述目标用户的IMSI所归属的运营商；Determine the operator to which the IMSI of the target user belongs;

根据所述目标用户的IMSI所归属的运营商，确定能够吸附所述目标用户设备的参考频段范围。According to the operator to which the IMSI of the target user belongs, determine a reference frequency band range capable of absorbing the target user equipment.

在目标用户设备拨打电话所应用的频段为2G频段的情况下，其中，每家运营商对应的2G频段分布存在不同，例如，中国移动对应的2G频段为上行：889-904MHz下行：934-949MHz；中国联通对应的2G频段为上行：904-915MHz下行：949-960MHz；中国电信对应的2G频段为上行：824-835MHz下行：869-880MHz；中国广电对应的2G频段为上行：703-733MHz下行：758-788MHz。When the frequency band used by the target user equipment to make calls is the 2G frequency band, the distribution of the 2G frequency bands corresponding to each operator is different. For example, the 2G frequency band corresponding to China Mobile is uplink: 889-904MHz and downlink: 934-949MHz The 2G frequency band corresponding to China Unicom is uplink: 904-915MHz downlink: 949-960MHz; the 2G frequency band corresponding to China Telecom is uplink: 824-835MHz downlink: 869-880MHz; the 2G frequency band corresponding to China Radio and Television is uplink: 703-733MHz downlink : 758-788MHz.
