Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a method, a device and a system for positioning a terminal after remote halo.
Background
The trunking communication system is a special wireless communication system applied to specific industries, can meet the demand of commanding and dispatching of industrial users, and is widely applied to the fields of government departments, public safety, emergency communication, electric power, civil aviation, petroleum, ports and the like.
The telecine revival is a basic service in the cluster communication system, and the dispatching desk sends an instruction to the cluster core network to trigger the cluster core network to send an air interface message to carry out the telecine revival operation on the appointed terminal. After the terminal is stunned, the terminal cannot apply for or receive any other services except for the services of attachment, registration, authentication, revival/remoting, positioning and the like. After the terminal is stunned, only the reactivation operation executed by the dispatching station with the authority is accepted, and the terminal can be restored to the normal working state after the reactivation is successful.
As a B-trunk broadband trunking communication system in a trunking communication system, the TD-LTE core technology is adopted, so that the characteristics of high speed and large bandwidth of the TD-LTE can be fused with the characteristics of resource sharing, quick call establishment, command scheduling and the like in the digital trunking technology, and high-speed data transmission is realized. The flow of the conventional B-true standard for the vignetting operation is shown in fig. 1:
1. a Dispatching station (DC) sends an sip (message) message to a TCF (Trunking Control Function) to initiate a halo Control operation for a specific terminal UE.
2, the TCF sends a Terminal StunKillRevie Request message to the eHSS in the B-Trunc, and informs the eHSS to perform the remote stun operation. The eHSS needs to record that the designated terminal is in the halo state.
And 3, the eHSS sends a Terminal stuntriilrevive Response message to the TCF, and feeds back the result of the operation.
The TCF sends a SIP (200OK) message to the DC to make the DC stun operation successful.
5, the TCF sends a User stun revivie Request message to the MME (Mobility Management Entity) to notify EPC (Evolved Packet Core) that the terminal is stunned;
MME sends KILL/STUN/REVIVE REQUEST (REMOTE-ARRESSION/REMOTE RESPONSE) message of NAS (Non-Access-Stratum) interface to the terminal, and informs the terminal to execute the REMOTE/REMOTE operation.
MME replying User stun revive Response User stun resurrection Response to TCF), indicating that the stun operation was successful. After receiving the halo request message, the MME judges whether the terminal has the exclusive bearer for broadband access, and triggers the exclusive bearer deactivation process.
In the process of implementing the scheme of the invention, the inventor finds that: since the B-TrunC standard requires that the terminal only has the positioning service after being vignetted but prohibits any other PS service, it is necessary for the xGW network element of the core network to identify the positioning service packet through packet detection, and to send the positioning service packet normally, and discard other packets. Because only the cluster core network MME unit is notified in the existing vignetting process and the xGW network element is not notified, the xGW network element cannot know whether the terminal is vignetted and cannot know the address of the location server, so that the xGW network element cannot support the location function of the terminal after being vignetted.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 2, an embodiment of the present invention provides a method for positioning a terminal after being stunned, including:
s1, the DC sends an SIP (message) message to the TCF, and initiates a remote halo control flow to the appointed terminal.
S2, the TCF sends a Terminal stuntriilRevive Request message to the eHSS, and notifies the eHSS to perform the halo operation. The eHSS needs to record that the terminal is in a state of being in the process of remote halo;
s3, eHSS sends a Terminal StunKillRevive Response message to the TCF, and feeds back the result of the operation;
s4, the TCF sends SIP (200OK) information to the DC to inform the DC that the telecine operation is successful;
s5, TCF sends User StunKillRevive Request message to MME, indicating EPC that the terminal is stunned, the message carries the address of the location server used by the terminal;
s6, MME sends KILL/STUN/REVIVE REQUEST message of NAS interface to the terminal, and informs the UE to execute the operations of stunning/reviving;
s7, the MME replies a User StunKillRevive Request message to the TCF to indicate that the vignetting operation is successful; if the terminal has the exclusive bearer for broadband access, triggering the exclusive bearer deactivation process;
s8, the MME needs to send a Modify Bearer Request message to the xGW network element, wherein the message carries a halo revival mark and a location server address corresponding to the terminal;
after receiving the Modify Bearer Request message, the network element S9, xGW stores the halo revival flag and the location server address corresponding to the terminal in the terminal context (data used for the terminal management), and replies a Modify Bearer Response message to the MME.
Correspondingly, after the xGW network element receives the uplink data sent by the terminal, if the terminal is in a remote halo state and the destination address is a location server address, the uplink data is sent from the SGi interface, otherwise, the uplink data packet is discarded;
xGW after the network element receives the downlink data packet, if the terminal is in the remote halo state and the source address is the address of the location server, then the downlink data is routed to the base station side. Otherwise, the downlink data packet is discarded.
In the embodiment of the invention, at an MME side, MME sends a remote halo/remote kill/revival request message to a terminal to instruct the EPC to execute remote halo/remote kill/revival operation. The location server address used by the terminal is carried in the telephoton/revival request message. When MME sends KILL/STUN/REVIVE REQUEST message to terminal NAS interface, the terminal executes the operations of STUN/revival. If the terminal has executed the stun/revival operation, the MME sends a user stun/revival response message to the TCF to indicate that the stun operation was successful.
At this time, the TCF generates a remote stun resurrection request message and sends the message to the MME. The MME sends a modification bearing request message carrying the location server address corresponding to the stunned terminal to the xGW network element, so that the xGW network element stores the stunned revival mark and the location server address corresponding to the stunned terminal in the context of the terminal. And then the MME receives a modified bearer response message fed back by the xGW network element.
In the embodiment of the present invention, at the side of xGW network element, after receiving a request message for modifying bearer from MME, the xGW network element stores the remote halo revival flag and the location server address corresponding to the terminal after being remotely halo into the context of the terminal, and then replies a response message for modifying bearer to MME; the modify bearer request message includes a location server address used by the telephotonic terminal.
When the modification of the bearer response message is successful, the xGW network element sends the uplink data of which the corresponding terminal is in the telephoton state and the destination address is the address of the location server from the SGi interface, and routes the downlink data of which the corresponding terminal is in the telephoton state and the source address is the address of the location server to the base station side.
When the modification of the bearer response message by the xGW network element is failed, or the terminal corresponding to the uplink data is not in the vignetting state and/or the destination address is not the address of the location server, or the terminal corresponding to the downlink data is not in the vignetting state and/or the source address is not the address of the location server, the uplink and downlink data are sent by the normal route.
In the process of implementing the embodiment of the present invention, the TCF needs to be sent to the MMF User stunting resurrection response message User stuntrillrevive Request. The modified User stun resurrection response message User stuntriilrevive Request is specifically described in table 1.
