Problems solved by technology
[0013] One of the objectives of the present invention is to provide a positioning method, device and system for a terminal after remote halo, which is used to solve the problem that the xGW network element is not notified during the remote halo process in the prior art, resulting in the xGW network element being unable to know whether the terminal is telephoto and positioned The problem caused by the server address that the above-mentioned xGW network elements cannot support the positioning function of the terminal after being remotely stunned

Embodiment Construction
[0050] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0051] Such as figure 2 As shown, the embodiment of the present invention provides a positioning method for a terminal after being fainted, including:
[0052] S1. The DC sends a SIP (Message) message to the TCF, and initiates a remote-stunning control procedure for the designated terminal.
[0053] S2. The TCF sends a Terminal StunKillRevive Request message to the eHSS, notifying the eHSS to perform a remote stun operation. eHSS needs to record that the terminal is in the state of remote fainting;
[0054] S3. eHSS sends a Terminal StunKillRevive Response message to TCF to feedback the result of this operation;
[0055] S4. The TCF sends a SIP (200OK) message to the ...

The invention relates to a positioning method, device and system for a terminal after being fainted. The method includes: after receiving the modification bearer request message from the MME, the xGW network element saves the telestunning resurrection flag and the location server address corresponding to the telestunned terminal into the context of the terminal, and then replies to the MME modifying the bearer response message; when the modifying the bearer response message indicates that the modification is successful, the xGW network element sends the uplink data whose corresponding terminal is in the telephoto state and whose destination address is the address of the location server from the SGi interface, and sends the corresponding terminal The downlink data whose source address is the address of the location server in the telephoto state is routed to the base station side. In the embodiment of the present invention, the address of the location server is added to the bearer modification request message and sent to the xGW network element, so that the xGW network element supports the positioning function of the terminal being remotely stunned.
Description
technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, device and system for locating a terminal after remote fainting. Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications, which can meet the command and dispatch needs of industry users, and is widely used in fields such as government departments, public safety, emergency communications, electric power, civil aviation, petroleum, and ports. [0003] Remote halo resurrection is a basic service in the trunking communication system. The dispatcher sends instructions to the cluster core network to trigger the cluster core network to send an air interface message to perform remote halo resurrection on the designated terminal. After the terminal is stunned, it cannot apply for or accept any other services except attachment, registration, authentication, resurrection / remot...
