Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic signaling interaction diagram of a location subscription method according to an embodiment of the present invention. The location subscription method is applied to a broadband trunking communication system and specifically comprises the following steps:

step S100, the first terminal (UE 1 shown in the figure) sends a location subscription request message (TSM SUBSCRIBE) to the clustered core network (T-CN shown in the figure).

Wherein the location subscription request message is used for indicating that the first terminal subscribes to the location information of the cluster group (including the UE2 and the UE3 … … shown in the figure); wherein, the message content of the location subscription request message is shown in table 1.

TABLE 1

Step S110, after receiving the location subscription request message sent by the first terminal, the Trunking core network sends a Trunking Paging message (Trunking Paging) carrying the location subscription request message to a Trunking base station (shown as eNodeB), and simultaneously returns an acknowledgement message (TSM SUBSCRIBE ACK) to the first terminal, where the acknowledgement message is used to indicate that the first terminal successfully requests location subscription. The contents of the confirmation message are specifically shown in table 2.

TABLE 2

It should be noted that after receiving the location subscription request message sent by the first terminal, the trunking core network needs to determine whether the first terminal has a location subscription right, and after determining that the first terminal has the location subscription right, the trunking core network sends a trunking paging message carrying the location subscription request message to the trunking base station, and simultaneously returns a confirmation message to the first terminal. Specifically, the cluster core network determines whether the first terminal has a location subscription right by acquiring subscription data of the first terminal.

Step S120, after receiving the cluster paging message carrying the location subscription request message sent by the cluster core network, the cluster base station initiates paging to the cluster group.

After receiving a cluster paging message carrying a location subscription request message sent by a cluster core network, a cluster base station initiates paging to a cluster group, and informs each terminal in the cluster group to report location information according to a reporting strategy issued by the cluster core network. The reporting policy may be determined according to circumstances, for example, the reporting policy may be periodic reporting, reporting after the mobile distance of the terminal reaches a certain number of meters, and the like.

Step S130, each terminal in the cluster group starts a location information reporting service after receiving a paging initiated by the cluster base station, and reports location information.

Specifically, after each terminal in the TRUNKING group meets a reporting policy issued by the TRUNKING core network, the terminal carries its own location information by a TRUNKING UPLINK transmission message (trunk UPLINK TRANSPORT) and reports the location information to the TRUNKING core network.

Step S140, the trunking core network issues, to the first terminal, the location information reported by each terminal in the trunking group.

After receiving the location information reported by each terminal in the cluster group, the cluster core network issues the location information reported by each terminal in the cluster group to the first terminal through a cluster DOWNLINK transmission message (trunk DOWNLINK TRANSPORT).

Specifically, the trunking core network may issue, to the first terminal, location information reported by each terminal in the trunking group according to a preset issuing policy, where the preset issuing policy includes immediate issuing and delayed packet issuing, and if the trunking core network determines immediate issuing, after receiving location information reported by a single terminal in the trunking group, the trunking core network immediately issues, to the first terminal, location information reported by the single terminal carried by a trunking downlink transmission message; if the cluster core network decides to delay the packet delivery and meets the packet delivery condition, after receiving the position information reported by all the terminals in the cluster group, the cluster core network delivers the position information by the cluster downlink transmission message carrying the packet message including the position information reported by all the terminals in the cluster group.

In the location subscription method provided by the embodiment of the invention, after a cluster core network in a broadband cluster communication system receives a location subscription request message which is sent by a first terminal and used for indicating the first terminal to subscribe location information of a cluster group; sending a cluster paging message carrying a location subscription request message to a cluster base station so that the cluster base station initiates paging to a cluster group, informs each terminal in the cluster group to start a location information reporting service after receiving the paging initiated by the cluster base station, and reports location information; receiving position information reported by each terminal in the cluster group; and issuing the position information reported by each terminal in the cluster group to the first terminal. That is, the position information of the cluster group is subscribed at the air interface in a broadcasting mode, and one subscription only needs to be sent once, so that the air interface resources are greatly saved.

It should be noted that after receiving the trunking paging message sent by the trunking core network, the trunking base station periodically initiates paging to the trunking group.

In this case, after the trunking core network sends the trunking paging message carrying the location subscription request message to the trunking base station, it further determines whether each terminal in the trunking group successfully receives the paging initiated by the trunking base station, and if not, determines a second terminal in the trunking group that does not successfully receive the paging initiated by the trunking base station, so that the second terminal reports the location information later.

Referring to fig. 2, fig. 2 is a schematic signaling interaction diagram of a method for reporting location information later according to an embodiment of the present invention, where the method includes:

step S200, the cluster base station initiates paging to the cluster group again.

In step S210, a second terminal (shown as UE2) in the cluster group starts a location information reporting service after receiving a paging initiated by the cluster base station, and reports location information.

Specifically, after the second terminal in the cluster group meets the reporting policy issued by the cluster core network, the second terminal carries its own location information by the cluster UPLINK transmission message (trunk UPLINK TRANSPORT shown in the figure) and reports the location information to the cluster core network.

Step S220, the trunking core network receives the location information reported by the second terminal in the trunking group, and issues the location information reported by the second terminal in the trunking group to the first terminal.

After receiving the location information reported by the second terminal in the cluster group, the cluster core network issues the location information reported by the second terminal in the cluster group to the first terminal through a cluster DOWNLINK transmission message (trunk DOWNLINK TRANSPORT).

Specifically, whether each terminal in the cluster group is powered on or cluster registered can be judged, and the terminal which is not powered on or registered in the cluster group is determined to be a second terminal which does not successfully receive the paging initiated by the cluster base station; or, judging whether the location information reported by each terminal in the cluster group is received within a preset time, and determining that the terminal which does not report the location information in the cluster group within the preset time is a second terminal which does not successfully receive the paging initiated by the cluster base station.

When the second terminal is not started or registered, the second terminal successfully executes EPS attachment after being started, then a cluster registration request is sent to a cluster core network, and after the cluster core network receives the cluster registration request sent by the second terminal, cluster registration is carried out on the second terminal according to the cluster registration request. Because the first terminal has subscribed the position information of the cluster group where the second terminal is, after the second terminal is successfully registered, the cluster core network judges that the second terminal needs to report the position information later. In particular, the method according to fig. 2 may be performed. And will not be described in detail herein.

Referring to fig. 3, fig. 3 is a schematic signaling interaction diagram of a method for canceling a location subscription according to an embodiment of the present invention, where the method specifically includes the following steps:

step S300, the first terminal sends a request message for canceling location subscription (TSM SUBSCRIBE CANCEL) to the trunking core network.

The location subscription cancellation request message is used for indicating the first terminal to cancel the location information of the subscription cluster group; the message content of the cancel location subscription request message is shown in table 3.

Step S310, after receiving the request message for canceling the location subscription sent by the first terminal, the trunking core network sends a trunking paging message carrying the request message for canceling the location subscription to the trunking base station, and simultaneously returns a cancellation confirmation message (TSM SUBSCRIBE CANCEL ACK) to the first terminal, where the cancellation confirmation message is used to indicate that the first terminal successfully requests to cancel the location subscription, and the content of the cancellation confirmation message is specifically shown in table 4.

It should be noted that after receiving the request message for canceling the location subscription sent by the first terminal, the trunking core network needs to determine whether the first terminal has the authority to cancel the location subscription, and after determining that the first terminal has the authority to cancel the location subscription, the trunking core network sends the trunking paging message carrying the request message for canceling the location subscription to the trunking base station, and meanwhile returns the cancellation confirmation message to the first terminal. Specifically, the trunking core network determines whether the first terminal has the authority to cancel the location subscription by acquiring the subscription data of the first terminal.

TABLE 3

TABLE 4

Step S320, after receiving the cluster paging message which is sent by the cluster core network and carries the request message for canceling the position subscription, the cluster base station initiates paging to the cluster group.

After receiving a cluster paging message carrying a request message for canceling the location subscription, which is sent by a cluster core network, the cluster base station initiates paging to the cluster group, notifies each terminal in the cluster group to cancel the location information reporting service, and stops reporting the location information.

It should be noted that, if a certain terminal in the trunking group does not successfully receive the paging initiated by the trunking base station, the terminal will report the location information once it meets the location reporting condition, after receiving the location reporting information, the trunking core network determines that the location subscription cancellation of the terminal is unsuccessful, the trunking core network issues a location subscription cancellation request message to the terminal point-to-point, after receiving the location subscription cancellation request message and successfully canceling the location subscription, the terminal returns a confirmation cancellation message to the trunking core network, and the content of the TSM SUBSCRIBE CANCEL ACK message is shown in table 4.

In a broadband trunking communication system, a dispatcher station may act as a proxy for a trunking group and subscribe to the location of a certain trunking terminal, as will be described in detail below.

Referring to fig. 4, fig. 4 is a schematic signaling interaction diagram of a location subscription method provided in the present invention, where the location subscription method is applied to a trunking core network in a broadband trunking communication system, and the method specifically includes the following steps:

in step 400, the dispatcher (DC shown in the figure) sends a proxy subscription message (sip (message)) to the cluster core network. The agent subscription message is used for indicating the dispatching desk agent cluster group to subscribe the position information of the first terminal.

Step 410, after receiving the proxy subscription message sent by the dispatching station, the trunking core network generates a location subscription request message (the message content is shown in table 5) according to the proxy subscription message, and sends the location subscription request message to the first terminal.

TABLE 5

Step 420, the trunking core network receives a confirmation message (the message content is shown in table 2) returned by the first terminal, where the confirmation message is used to instruct the first terminal to accept the location subscription request and report location information after meeting a reporting policy.

In step 430, the cluster core network sends a proxy subscription response message (SIP (200OK)) to the dispatcher.

Step 440, the first terminal reports the location information to the cluster core network.

It should be noted that the first terminal reports the location information of the first terminal to the trunking core network according to a reporting policy issued by the trunking core network, where the reporting policy may be determined according to circumstances, such as periodic reporting, reporting after the moving distance of the terminal reaches several meters, and the like, and the present invention is not limited thereto. Specifically, the first terminal reports the location information of the first terminal to the TRUNKING core network through a TRUNKING UPLINK transmission message (trunk UPLINK TRANSPORT).

Step 450, after receiving the location information reported by the first terminal, the trunking core network sends a trunking paging message carrying the location information reported by the first terminal to the trunking base station.

Specifically, the trunking core network may send a trunking paging message carrying the location information reported by the first terminal to a trunking base station according to a preset issuing policy, where the preset issuing policy includes immediate issuing and delayed issuing, and if the trunking core network determines immediate issuing, after receiving the location information reported by the first terminal, the trunking core network immediately sends a trunking paging message carrying the location information reported by the first terminal to the trunking base station, so that the trunking base station initiates paging to a trunking group to notify each terminal in the trunking group to receive the location information reported by the first terminal; or, if the trunking core network decides to issue the location information in a delayed manner, after receiving the location information reported by the first terminal, the trunking core network delays to send a trunking paging message carrying the location information reported by the first terminal to the trunking base station, so that the trunking base station initiates paging to the trunking group to notify each terminal in the trunking group to receive the location information reported by the first terminal.

Step 460, the cluster base station initiates paging to the cluster group, and notifies each terminal in the cluster group to receive the location information reported by the first terminal.

In the location subscription method provided by the embodiment of the invention, a cluster core network in a broadband cluster communication system receives an agent subscription message sent by a dispatching desk, wherein the agent subscription message is used for indicating the dispatching desk to subscribe a cluster group to subscribe the location information of a first terminal; generating a position subscription request message according to the agent subscription message; sending the location subscription request message to the first terminal; receiving a confirmation message returned by the first terminal, wherein the confirmation message is used for indicating the first terminal to accept the position subscription request and report the position information after meeting a reporting strategy; receiving the position information reported by the first terminal; and sending a trunking paging message carrying the position information reported by the first terminal to a trunking base station so that the trunking base station initiates paging to a trunking group and informs each terminal in the trunking group to receive the position information reported by the first terminal. That is, the subscribed position information is sent to the cluster group at the air interface in a broadcasting mode, and only one subscription needs to be sent, so that air interface resources are greatly saved.

Referring to fig. 5, fig. 5 is a schematic signaling interaction diagram of a method for canceling a location subscription according to an embodiment of the present invention, where the method specifically includes the following steps:

step S500, the dispatching desk sends a message of canceling the proxy subscription.

The unsubscribe agent subscription message is used to instruct the dispatcher agent cluster group to unsubscribe the location information of the first terminal, and the message content of the unsubscribe agent subscription message is shown in table 6.
