System and method for detecting lost position of communication device

The present invention relates to a detection system and method, and more particularly to a system and method for detecting a lost position of a communication device.

Currently, handheld mobile electronic devices are being used in an increasingly wide range of environments that provide great convenience for communication, entertainment, and data exchange. The main handheld mobile electronic devices include mobile phones, PDAs (personal digital assistants), handheld game consoles and digital cameras.

With the continuous application of handheld mobile electronic devices, handheld mobile electronic devices are becoming more and more powerful. In addition to the value of the handheld mobile electronic device itself, the handheld mobile electronic device also stores a large amount of private information, such as call records, phone books, private messages, encrypted data and transaction authentication information. Therefore, once the handheld mobile device is lost, it may cause significant damage to the user. However, most mobile phones currently do not automatically detect whether they are in a lost state. Only when the user finds that the phone is lost, he relies on remembering where the phone may be lost.

In view of the above, a preferred embodiment of the present invention provides a system and method for detecting a lost location of a communication device, which can identify that the communication device may be lost when the duration of the stay of the communication device reaches an allowable dwell time in a region to which the base station belongs. Status and issue a warning notification.

Identifying that the communication device is in a lost state during the dwell time; and notifying the module to send a warning notification when the communication device is in a lost state.

A method for detecting a lost position of a communication device, the communication device comprising a SIM card and a memory, wherein the memory stores the number of times the communication device passes through each base station, the method comprising: (a) according to a memory The communication device classifies the base station by the number of times each base station belongs, and sets an allowable stay time corresponding to each level; (b) enters a base station area; (c) connects the base station to the network and acquires The identification code of the base station; (d) identifying the level of the base station and its corresponding allowed stay time according to the identification code of the base station; and (e) when the communication device stays in the area to which the base station belongs The communication device is identified as being in a lost state and a warning notification is sent upon the set allowable dwell time.

Compared with the prior art, the system and method for detecting the lost position of the communication device may classify the base station according to the number of times each base station belongs to the communication device and set an allowable dwell time for each level. When the communication device reaches the set allowable dwell time in the area where the certain base station belongs, the communication device is identified as being in a lost state and a warning notice is issued, thereby greatly reducing the probability of the communication device being lost.

As shown in FIG. 1 , it is a functional module and an application environment diagram of a system for detecting a lost position of a communication device according to the present invention. The system 10 (hereinafter referred to as "detection system 10") for detecting the lost position of the communication device operates in the communication device 1. The communication device 1 is connected to the base station 4 via a mobile network. After detecting that the communication device 1 is lost, the detection system 10 automatically sends a warning notification to the pre-bound communication device 3 through the base station 4. The user can turn the detection system 10 on or off according to his own needs.

The communication device 1 includes a timer 150 and a SIM (Subscriber Identity Model) card 160.

The timer 150 is used for timing.

The SIM card 160 is a smart card containing a large integrated circuit for registering important information and information of the user.

The data stored by the SIM card 160 can be classified into four categories: The first type is fixed storage data. This type of information is written by the SIM card center before the mobile phone is sold, including the International Mobile Subscriber Identification Number (IMSI), authentication secret Key (KI), authentication and encryption algorithms, and more. The second category is temporary information about the Internet. Such as location area identification code (LAI), mobile subscriber temporary identification code (TMSI), public telephone network code forbidden access, and the like. The third category is related business codes such as personal identification number (PIN), unlock code (PUK), billing rate, and the like. The fourth category is the telephone directory, which is the telephone number that the mobile phone user can enter at any time. All of the user's data is stored in the SIM card, so the SIM card is also called the user data identification card. Each SIM card corresponds to a unique IMSI code, so the IMSI code can also be used as an identifier for identifying the SIM card.

The communication device 1 further includes a memory 180. The memory 180 stores various types of data, including various applications, and data set and generated during the process of using the detection system 10, for example, the communication device 1 passes through The number of times each base station 4 belongs to, the CELL-ID (base station identifier) corresponding to each base station, and the IMSI code information of the SIM card 160. The CELL-ID is an identifier used globally, and each base station 4 has a unique CELL-ID. The CELL-ID is composed of MCC (mobile country code) + MNC (mobile network code) + LAC (location area identity). +CI (cell identity) and other components.

The memory 180 can be built in the communication device 1, and can also be a separate external storage card, such as a SIM card (Smart Media Card), an SD card (Secure Digital Card), a CF card ( Compact Flash Card, Standard Flash Memory Card, MMC Card (Multi Media Card), MS Card (Memory Stick), XD Card (Extreme Digital Card), TF Card (Trans) Flash Card) and so on.

The detection system 10 includes a setting module 100, a connection module 110, a detection module 130, and a notification module 140.

The setting module 100 is configured to divide the corresponding level according to the number of times the communication device 1 is stored in the memory 180 through the area to which each base station 4 belongs, and set an allowable dwell time corresponding to each level. For example, the rating is divided into five levels: frequent, frequent, occasional, rare, and never equal. The level can be set and modified according to actual needs. The allowable dwell time refers to setting a dwell time for different levels. For example, the allowable dwell time of a base station rated "frequent" can be set to "10 hours."

The setting module 100 is further configured to set a time for allowing the replaced SIM card to be used in the communication device 1 when the SIM card is replaced, and a number of the notification object when the communication device 1 is in a lost state (ie, binding The number of the communication device 3). For example, when the communication device 1 converts a SIM card, the setting module 100 is configured to allow the SIM card to be used in the communication device 1 for half an hour, and when it is more than half an hour, the communication device 1 is identified as being in a lost state. A warning notification is issued to the binding communication device 3 to alert the user to the location where the communication device 1 is lost.

The connection module 110 is configured to perform network connection and acquire the CELL-ID of the base station 4 when the communication device 1 enters an area to which the base station 4 belongs.

The detecting module 130 is configured to detect whether the staying time of the communication device 1 at the base station 4 of the CELL-ID reaches a set allowable dwell time corresponding to the CELL-ID base station.

The notification module 140 is configured to send a warning notification to the bound communication device when the detection module 130 detects that the communication device 1 has reached the set residence time of the base station 4 The number of 3. The warning notification includes: "The communication device 1 is lost within the range of the base station with the CELL-ID being XXXX." The notified user can search for the communication device 1 according to the above warning notification, thereby greatly narrowing the user search range.

The detection module 130 is further configured to detect whether the currently used SIM card of the communication device 1 has been replaced, and the detection manner is as follows: according to the IMSI code information and current of the SIM card stored in the memory It is judged whether the IMSI code information of the SIM card used by the communication device 1 is consistent.

The notification module 140 is further configured to: when the detection module 130 detects that the SIM card of the communication device 1 has been replaced, and the usage time of the replaced SIM card in the communication device 1 reaches the set allowable usage time At the time, a warning notification is issued to the bound communication device 3.

The detection system 10 further includes a recording module 120 for recording the number of times the communication device 1 passes through the area of the base station 4 of each different CELL-ID. As shown in FIG. 3, the route A and the route B that the communication device 1 passes respectively pass through the area to which the base station of the different CELL-ID belongs, and the route A passes through the base station with the CELL-ID of "7, 8, and 9". The route B passes through the area of the base station through which the CELL-ID is "3, 7, 11", and the recording module 120 records the area of the base station to which the communication device 1 passes each different CELL-ID. frequency.
