Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for acquiring identification information of a mobile device.
Background
The International Mobile Equipment Identity (IMEI) is a unique identifier of each legitimate Mobile device, and is generally stored in an eeprom (electrically Erasable Programmable read only memory) of the Mobile device. The IMEI is particularly important in identity recognition because the IMEI can uniquely identify a mobile device, for example, in criminal investigation, technical investigation and lawful interception of communication management and control, obtaining the IMEI is an important means for identifying and locating the mobile device.
Taking LTE network as an example, at present, the process of acquiring IMEI of a mobile device in the prior art is as follows: the method comprises the steps that under the condition that the IMEI of the mobile equipment needs to be acquired, the network side equipment sends an identification Request (Identity Request) message to the mobile equipment, the mobile equipment returns an identification Response (Identity Response) message after receiving the identification Request message sent by the network side equipment, and the returned identification Response message carries the IMEI of the mobile equipment, so that the IMEI acquisition process is completed.
It can be seen that the general procedure for acquiring the IMEI is only applicable to a scenario where the mobile device resides in a certain Tracking Area, and in a scenario of Tracking Area Update (TAU), if the network side device still acquires the IMEI in the above manner, the IMEI of the network side device will not be reported to some mobile devices, which is caused by different implementation manners of different terminal manufacturers for the scenario, thereby resulting in a problem of low reporting rate. The prior art does not relate to how to solve or improve the problem of low IMEI reporting rate in the TAU process.

In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.

Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.
In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.
Before describing the method for acquiring the mobile device identification information provided by the embodiment of the present invention, some concepts involved in subsequent embodiments and basic principles of acquiring the mobile device identification information will be described.
First, it should be noted that the method for acquiring the Mobile device identification information provided by the present invention may be used for acquiring an imei (international Mobile Equipment identity) and may also be used for acquiring an meid (Mobile Equipment identity). Wherein, IMEI is the identification code used by GSM, WCDMA mobile phone, and is distributed and managed by GSM (Global System for Mobile communications Association); the MEID is an identification code used by CDMA handsets, and is uniformly assigned and managed by TIA (telecommunications industry association). An "electronic serial number" consisting of 15 digits, which corresponds one-to-one to each mobile device, is unique worldwide. It should be noted that the identification information of the mobile device related in the embodiment of the present invention may be an IMEI, or an meid (mobile Equipment identifier) of a CDMA mobile device
In the following, in each embodiment of the present invention, an IMEI of a mobile device is acquired in an LTE network as an example.
In order to confirm the location of a mobile device in a network, an LTE network coverage Area is divided into a plurality of Tracking Areas (TAs), and TAs are basic units for location update and paging in the LTE network, that is, when the mobile device moves within a Tracking Area, the network can find the mobile device by sending a paging message. When the mobile device moves out of the Tracking Area range, in order to page the mobile device during downlink service, a Tracking Area Update (TAU) procedure needs to be performed, that is, a new Tracking Area is registered to notify the network of the current location of the mobile device.
It should be noted that each TA is identified by using Tracking Area Code (TAC), and one TA may include one or more cells.
Because the IMEI of the mobile device is acquired by issuing the identification request through the network side device in the prior art, the problem of low reporting rate of the IMEI of the mobile device is caused in the tracking area updating process, the invention provides a scheme for acquiring the identification information of the mobile device, which can be applied to but limited to any tracking area updating process of an LTE network as follows: normal tracking area updating, periodic tracking area updating, tracking area updating caused by switching between different eNodeBs in the same MME, and tracking area updating between different MMEs. Wherein, the normal Tracking Area update is that when the mobile device detects that the Tracking Area identifier of the resident cell changes and is not in a Tracking Area Identifier (TAI) list, the mobile device initiates the normal Tracking Area update to notify the network side device that the mobile device enters a new Tracking Area range; the periodic tracking area update means that the mobile device regularly informs the network of the location of the mobile device, and is triggered by the timeout of a timer in the mobile device.
After the mobile device passes through any of the above tracking area update procedures, the network side device receives a tracking area update request sent by the mobile device, and if the network side device rejects the tracking area update, the network side device sends a tracking area update rejection message to the mobile device, where the rejection message includes a rejection cause value, which may be, but is not limited to, any one of the cause values shown in table 1. After receiving the tracking area update reject message, the mobile device responds differently according to different reject cause values contained in the received tracking area update reject message, for example, when the cause value is 3 (that is, the reject cause is that the mobile device is an illegal device), the mobile device sets that the USIM is invalid and does not process any service until rebooting or USIM reinsertion; when the reason value is 12 (namely the rejection reason is that the tracking area is not allowed), cell search is carried out, and an attachment process is sent once after the cell search is resident; when the cause value is 15 (i.e. the reject cause is that there is no suitable cell in the tracking area), the mobile device will perform cell search in other tracking areas, and perform normal service after successful residence, without performing an attach process again.
TABLE 1 partial cause values for TAU rejection and corresponding processing method
In the application scenario, the mobile device is triggered to initiate a network attachment process again by changing the rejection cause value contained in the tracking area rejection message, so that the identification information (for example, IMEI) of the mobile device is acquired in the network attachment process initiated again, and the success rate of acquiring the identification information of the mobile device in the tracking area update scenario is improved.

Optionally, the network side device executes the tracking area update procedure under the condition that the network side device does not need to acquire the identification information of the mobile device.
As an optional implementation manner, the tracking area update reject message may be made to carry a reject cause value used for indicating that the network side device cannot identify the identification information of the mobile device. For example, reject cause value 9 in LTE networks (i.e., reject cause is the network's inability to acquire the IMEI of the mobile device).
Step S203, the network side device sends an identification request message to the mobile device when receiving a network attach request sent by the mobile device, where the identification request message is used to request identification information of the mobile device.
Specifically, after the network side device sends a tracking area update reject message to the mobile device, the mobile device may reinitiate the network attach request, so that the network side device sends an identification information identification request message for requesting the mobile device to the mobile device if the network side device wants to acquire the identification information of the mobile device in the case of receiving the network attach request sent by the mobile device. Optionally, the network-side device executes the network attach procedure under the condition that the network-side device does not need to acquire the identification information of the mobile device.

For example, in an LTE network, the preset reject cause value may be 9 (i.e., the reject cause is that the network cannot acquire the IMEI of the mobile device).
As an alternative implementation, the step S302 may include: the mobile equipment receives a tracking update rejection message returned by the network side equipment according to the tracking area update request; the mobile equipment decodes the tracking update rejection message to obtain a preset rejection reason value; and the mobile equipment sends a network attachment request to the network side equipment according to a preset rejection reason value.
