Problems solved by technology

[0009] The mobile terminal needs to complete the update of the tracking area first, and then perform the detach operation again. This method leads to a large amount of signaling interaction on the air interface, and there is a problem of repeated transmission on the wireless channel, and the user has already left the network, so there is no need to re-attach. Tracking area updates

Embodiment 1

[0052] An embodiment of the present invention provides a method for detachment of a mobile terminal, the mobile terminal has left the original network area, see figure 1 , the method includes:

[0053] 101: The new mobility management device receives the detach request message sent by the mobile terminal, and the detach request message carries the location identifier and the user temporary identifier saved by the mobile terminal;

[0054] 102: The new mobility management device sends a detach instruction message to the original mobility management device indicated by the location identifier, and the detach instruction message carries the user temporary identifier, so that the original management device performs the detach operation according to the user temporary identifier;

[0055] Wherein, the new mobility management device sends a detach instruction message to the original mobility management device indicated by the location identifier, so that the original management devi...

Embodiment 2

[0083] When the mobile terminal leaves the original network area before completing the detach process, in order to realize that the mobile terminal does not need to complete the tracking area update before performing the detach process again, so as to avoid the interaction of a large number of signaling on the air interface and the presence of For the problem of repeated transmission, the embodiment of the present invention provides a method for detachment of the mobile terminal. In the embodiment of the present invention, the area where the mobile terminal is located takes the tracking area TA under the EPS network as an example. Refer to figure 2 , the specific implementation content is as follows:

[0084] 201: The mobile terminal sends a detachment request message to the new MME, and the detachment request message carries a GUTI.

[0085] Wherein, since the mobile terminal has left the original network area and arrived at the new network area before completing the detachmen...

Embodiment 3

[0114] When the mobile terminal leaves the original network area before completing the detach process, in order to realize that the mobile terminal does not need to complete the routing area update before performing the detach process again, so as to avoid the interaction of a large number of signaling on the air interface and the presence of For the problem of repeated sending, the embodiment of the present invention provides a method for deattaching the mobile terminal. In the embodiment of the present invention, the area where the mobile terminal is located takes the routing area RA under the GPRS network as an example. Refer to Figure 4 , the specific implementation content is as follows:

[0115] 301: The mobile terminal sends a detachment request message to the new SGSN, where the detachment request message carries a routing area identifier RAI and a temporary user identifier P-TMSI.

[0116] Wherein, since the mobile terminal has left the original network area and arri...

Abstract

The embodiment of the invention provides a de-adherence method for a mobile terminal which has left the original network area. The method comprises the following steps of: receiving a de-adherence request message sent by the mobile terminal, wherein the de-adherence request message carries a position identifier and a user temporary identifier which are stored in the mobile terminal; sending a de-adherence indicative message to an original mobility management device indicated by the position identifier, wherein the de-adherence indicative message carries the user temporary identifier, so that the original mobility management device carries out de-adherence operation according to the user temporary identifier; and receiving a de-adherence indicative response message which is sent by the original mobility management device after carrying out de-adherence operation. The embodiment of the invention provides a de-adherence system for the mobile terminal, which comprises a new mobility management device and the original mobility management device. The de-adherence method, the de-adherence system and the de-adherence device for the mobile terminal which are provided by the embodiment of the invention have the advantages of saving bandwidth and improving efficiency without updating tracking regions before carrying out de-adherence process again on the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, system and device for deattaching a mobile terminal. Background technique [0002] With the development of wireless communication, in UMTS (Universal Mobile Telecommunications System, Universal Mobile Communication System) and its evolved network EPS (Evolved Packet System, Evolved Packet System), in order to know the location of the mobile terminal, the network requires the mobile terminal to It is necessary to register in the network, and this operation is called attaching; when a mobile terminal is attached to the network, the network will record the area where the mobile terminal is currently located, which is a collection of multiple cells. Among them, in GSM (Global System for Mobile communications , Global System for Mobile Communications), UMTS network circuit domain is called LA (Location Area, location area), in GPRS (General Packet Radio Service, g...
