Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
With the rapid development of mobile communication networks, private network digital trunking communication systems provide more and more comprehensive services for users in the aspects of service types, terminal performance and the like. In the industries of rail transit, emergency command and rescue and the like, a user has more accurate and real-time scheduling requirements for a front-line worker in a private network cluster system, and meanwhile, in order to enhance the maneuvering flexibility of the front-line worker and enhance the sharing and communication of information, the user has new requirements for positioning services and services such as position information sharing between terminals. The cluster positioning service function is reported to the dispatching desk DC by the cluster terminal for the dispatching desk DC to carry out flat command, and the command center carries out on-site dispatching command tasks according to the visual position information, so that the maneuvering capability of command and dispatching is improved, and greater convenience is brought to rapid and accurate handling of emergency events.
The cluster communication positioning command system based on the TD-LTE comprises a terminal UE, a base station eNodeB, a cluster core network, a dispatching station DC, a geographic information system Server (GIS Server), and the like, and is divided into a single-core network and a cross-core network architecture, fig. 1 is a schematic diagram of a single-core network broadband cluster system architecture in the prior art, and fig. 2 is a schematic diagram of a cross-core network broadband cluster system architecture in the prior art.
The existing positioning service is an application layer service, as shown in fig. 1 and 2. And the terminal UE or the dispatching desk DC interacts with the GIS server through an application layer. The method comprises the steps that a dispatching desk DC initiates a position subscription process for a certain UE or a certain group to a GIS server, the GIS server configures information such as a positioning switch and parameters to the UE, the UE reports position information according to the configured parameters, and the GIS server forwards the position information to the dispatching desk DC. The method comprises the following specific steps:
reporting mode of cluster UE: the UE supports reporting of various position formats such as a GPS, a Beidou and a cell, and parameters such as a reporting switch, a period and a distance of each UE are flexibly configurable, so that position control of various accuracies of the terminal is supported.
And (3) subscribing by a dispatching desk: the dispatching desk can subscribe the position information of a plurality of terminals and groups, and the member information of the groups is interactively acquired by the GIS server and the cluster core network, so that the dispatching desk does not need to inquire or manually input the information of the group members.
The subscription mode is as follows: the method supports real-time subscription, timing subscription and historical track query, facilitates the dispatching desk to acquire the position information of the UE or the group at any time, and adapts to various positioning application scenes.
Positioning and scheduling are combined: the user can initiate voice or video calls to any group or UE presented on the map, improving the efficiency of the command.
Lost UE recovery: when the UE is lost, the dispatching console can stun or kill the lost terminal for information security, so that the terminal cannot perform any service, but the positioning service can still continue to operate, and is convenient for being retrieved in time.
And a GIS server: the method comprises the steps of supporting the login and exit management functions of UE and a DC, configuring positioning parameters, receiving positioning information reported by the UE and forwarding the positioning information to the DC, supporting the DC to subscribe or unsubscribe position information to the UE, supporting the code number analysis and group member query functions, acquiring a member list of a group by a GIS server through an internal interface of a cluster core network, distributing subscription information among the GIS servers, and forwarding terminal position information.
In the existing trunking system positioning service scheme, a scheduling station DC initiates a location subscription process for a certain UE or group to a GIS server under a single core network architecture, the GIS server configures information such as a positioning switch and parameters to the UE, the UE reports location information according to the configured parameters, and the GIS server forwards the location information to the scheduling station DC. Under the cross-core network architecture, GIS servers finish GIS server positioning information forwarding through application layer interaction. Therefore, the dispatching desk can know the real-time distribution of front-line workers through the positioning information reported by the terminal in real time.
However, the existing positioning service only reports the positioning information of each terminal and the group to the GIS server, only the dispatching desk DC of the dispatching command center can check the position of the terminal personnel at the first line, and the first-line staff cannot acquire the position information of other personnel, so that the cooperative efficiency among the group members is reduced, and the autonomy of the first-line staff is limited.
In addition, the terminal cannot acquire the position information of other terminals, and the requirement that the vehicle-mounted terminal acquires the positions of the front and rear adjacent trains in real time in the rail transit cannot be met.
Moreover, since the terminal is generally moved unlike the DC, the DC is substantially fixed, and thus the DC is not subject to accidents caused by being too close to other terminals. When the terminal is used in a vehicle-mounted scene, a ship-mounted scene and the like, information of nearby vehicles or ships cannot be sensed in places with poor sight lines or in high-speed driving, and accidents are easily caused due to the fact that a dispatching desk is lost or messages are issued late.
In order to solve the above technical problem, an embodiment of the present invention provides a method for subscribing location information between clustered terminals, where a terminal initiates a location information subscription request to a GIS server to which the terminal belongs, and the terminal can subscribe location information of one or more terminals or one group at a time, so that the terminals can obtain current locations of other terminals in real time without the participation of a dispatching desk DC, and thus flexibility and accuracy of field decision are improved.
The mechanism can provide real-time position information of front and back adjacent trains between vehicle-mounted terminals in rail transit, provides visual train position and running information for train drivers, and provides guarantee for safe running of the trains.
In some places with poor sight lines or in high-speed driving, the terminal user can use the method to subscribe the range, and obtain other terminal positions in the range according to the set range value, so that some accidents are avoided.
Fig. 3 is a schematic diagram of a method for subscribing to location information between cluster terminals according to an embodiment of the present invention, and as shown in fig. 3, an embodiment of the present invention provides a method for subscribing to location information between cluster terminals, where an execution subject is a cluster terminal. The method comprises the following steps:
step S301, sending position subscription request information aiming at a target terminal to a Geographic Information System (GIS) server; and the GIS server is a GIS server to which the cluster terminal which sends the position subscription request information belongs.
Specifically, when a user needs to acquire location information of another terminal, location subscription request information for a target terminal (subscribed UE) is sent to a GIS server through a trunking terminal (main subscription UE), where the trunking terminal (main subscription UE) that sent the location subscription request information belongs to.
The main subscription UE may subscribe to the location information of one or more UEs or a group at a time, or may subscribe to the location information of one or more UEs and a group at the same time. The location subscription request information may carry a user identifier UDN of the subscribed UE and/or a group identifier GDN of the group, and the location subscription request information may also carry a location range and location parameters suggested by the terminal, including a period reported by the terminal and a moving distance parameter.
The main subscribing terminal and the subscribed terminal can be terminals in the same core network, and can also be terminals across the core network.
If a plurality of subscribed UEs belong to the same GIS server, only one subscription request is sent to the GIS server. And the GIS server to which the subscribed UE belongs returns a response message to the GIS server to which the main subscription UE belongs, wherein the response message comprises a response result of whether each UE is subscribed successfully or unsuccessfully.
Step S302, receiving the position information of the target terminal fed back by the GIS server; and the position information of the target terminal is determined by the GIS server according to the position subscription request information.
Specifically, after receiving the location subscription request information, the GIS server to which the main subscription UE belongs determines the location information of the subscribed UE according to the location subscription request information.
And after the GIS server to which the main subscription UE belongs determines the position information of the subscribed UE, the GIS server issues the position information to the main subscription UE.
And the main subscription UE receives the position information of the subscribed UE fed back by the GIS server to which the main subscription UE belongs.
The embodiment of the invention provides a method for subscribing position information among cluster terminals, which enables the terminals to acquire the current position information of other terminals in an active subscription mode, realizes mutual subscription of the position information among the cluster terminals and meets the requirements of more application scenes.
Based on any of the above embodiments, further, the location subscription request information includes a subscription mode, and the subscription mode is used for representing a subscription mode for subscribing location information desired by a user.
Specifically, in order to meet the needs of different users and different application scenarios, in the embodiment of the present invention, the location subscription request information includes a subscription mode, and the subscription mode is used to represent a subscription mode of location information desired by a subscriber.
For example, if the location information to which the user desires to subscribe is fed back in real time, the real-time subscription mode may be selected.
Fig. 4 is a schematic diagram of a real-time subscription process provided in the embodiment of the present invention, and as shown in fig. 4, the real-time subscription process is as follows:
step 1: the main subscription UE sends a location information subscription request message (XMPP Subscribe), and the main subscription UE may Subscribe to location information of one or more UEs or a group at a time, or may Subscribe to location information of one or more UEs and a group at the same time. The message carries the UDN of the subscribed UE and/or the GDN of the group, and the subscription message may carry the location range and location parameters suggested by the terminal, including the period reported by the terminal and the moving distance parameters.
Step 2a-3 a: for one or more subscribed single UE, the GIS Server to which the main subscription UE belongs obtains the GIS Server to which the subscribed UE belongs according to the code number analysis, and forwards the subscription request to the GIS Server. If a plurality of subscribed UEs belong to the same GIS Server, only one subscription request is sent to the GIS Server. And the GIS Server to which the UE belongs returns a response message to the GIS Server to which the main subscription UE belongs, wherein the message comprises a response result of whether each UE is subscribed successfully or unsuccessfully.
Step 6b-7 b: the GIS Server forwards the subscription request to the GIS Server to which the group member belongs according to the code number analysis, and if a plurality of group member UEs belong to the same GIS Server, only one position subscription request is sent to the GIS Server. And the GIS Server to which the group member belongs returns a response message to the GIS Server to which the group member belongs, wherein the response message comprises a response result of whether the position subscription of each UE is successful or failed, and the GIS Server to which the group member belongs returns a response message to the GIS Server to which the DC belongs, and the message comprises a response result of whether the subscription of each UE in the local position subscription is successful or failed.
And 8: and the GIS Server to which the main subscription UE belongs combines the response messages of 3a and 7b and sends the combined message to the DC, wherein the message contains the response result of each UE.
Note 1: the two processes 2a-3a and 2b-7b may be concurrent.
Note 2: if the GIS Server to which the main subscription UE belongs has subscribed the location information of the UE or the group, the 2a-7b procedure may be absent.
The embodiment of the invention provides a method for subscribing position information among cluster terminals, which enables the terminals to acquire the current position information of other terminals in an active subscription mode, realizes mutual subscription of the position information among the cluster terminals and meets the requirements of more application scenes.
Based on any of the above embodiments, further, the subscription mode is one of a real-time subscription, a unsubscribe, a timing subscription, and a scope subscription.
Specifically, in order to meet the needs of different users and different application scenarios, in the embodiment of the present invention, the location subscription request information includes a subscription mode, and the subscription mode is used to represent a subscription mode of location information desired by a subscriber. The subscription mode is one of a real-time subscription, a unsubscribe, a timing subscription and a scope subscription.
Fig. 5 is a schematic diagram of a unsubscribe process according to an embodiment of the present invention, where as shown in the figure, the unsubscribe process is as follows:
step 1: the active unsubscribing UE initiates a location unsubscribing service for other UEs to a GIS Server which the active unsubscribing UE belongs to, can unsubscribe location information of one or more UEs or a Group at one time, and can also simultaneously unsubscribe location information of one or more UEs and a Group. The message carries the UDN of the unsubscribed UE and/or the GDN of the group.
Step 2a-3 a: for one or more single UE which is unsubscribed, the GIS Server to which the UE which is actively unsubscribed belongs obtains the GIS Server to which the UE which is unsubscribed belongs according to the code number analysis, and forwards the unsubscribe request to the GIS Server. If a plurality of UE to be unsubscribed belong to the same GIS Server, only one position unsubscribe request is sent to the GIS Server. And the GIS Server to which the UE belongs returns a response message to the GIS Server to which the UE actively subscribes the position information, wherein the message comprises a response result of whether the unsubscribing of each UE position succeeds or fails.
And 4, step 4: and the GIS Server to which the UE actively unsubscribes belongs merges the response messages of the 3a and the 3b and sends the response messages to the UE actively subscribing the position information, wherein the response messages comprise the position unsubscribing response result of each UE.
Note: the two processes 2a-3a and 2b-3b may be concurrent.
The embodiment of the invention provides a method for subscribing position information among cluster terminals, which enables the terminals to acquire the current position information of other terminals in an active subscription mode, realizes mutual subscription of the position information among the cluster terminals and meets the requirements of more application scenes.
Based on any of the above embodiments, further, when the subscription mode is a timing subscription, the location subscription request information further includes a start-stop time of the subscription.
Specifically, in the embodiment of the present invention, when the subscription mode is a timed subscription, the location subscription request information further includes a start-stop time of the subscription.
Fig. 6 is a schematic diagram of a timing subscription process provided in an embodiment of the present invention, and as shown in fig. 6, the timing subscription process is as follows:
step 1: the main subscription UE initiates a location subscription service for the UE to a GIS Server to which the main subscription UE belongs, and the message contains a Begin Time field and an End Time field, namely the process is a timed subscription flow. The main subscription UE may subscribe to the location information of one or more UEs or a group at a time, or may subscribe to the location information of one or more UEs and a group at the same time. The message carries UDN of subscribed UE and/or GDN of group, and the location subscription message may carry positioning parameters suggested by DC, including period and moving distance parameters reported by the terminal.
Step 2: and the GIS Server to which the main subscription UE belongs returns a position subscription response message to the main subscription UE.
And step 3: and when the Begin Time is up, initiating a real-Time subscription process by the GIS Server to which the main subscription UE belongs, wherein the process is the same as that of 2a-7b in the real-Time subscription process of the terminal.
And 4, step 4: and when the End Time reaches, initiating a position unsubscribing process by a GIS Server to which the main subscription UE belongs, wherein the process is the same as the terminal unsubscribing process 2a-3 b.
Note 1: when the value of Begin Time is 0, it indicates immediate subscription, and step 2 may be performed after step 3, so that the subscription result may be carried in the XMPP Subscribe ACK message.
Note 2: when the value of EndTime is 0, the task is never ended, and if the subscription process of a certain task is to be stopped, the UE which needs to actively unsubscribe triggers the subscription process.
Note 3: before the EndTime arrives, the actively unsubscribed UE may trigger a unsubscribe procedure to cancel the subscription.
The embodiment of the invention provides a method for subscribing position information among cluster terminals, which enables the terminals to acquire the current position information of other terminals in an active subscription mode, realizes mutual subscription of the position information among the cluster terminals and meets the requirements of more application scenes.

Specifically, in the embodiment of the present invention, when the subscription mode is a scope subscription, the location subscription request information further includes a subscription scope, and the target terminal is within the subscription scope included in the location subscription request information.
For example, the flow of the scope subscription may include the following two schemes:
firstly, the process of the range subscription is the same as the timing subscription or the real-time subscription, and only one MsgDistance field is added to the subscribed xmpp message to set a distance a, wherein the distance is used for representing that only the positions of other subscribed terminals which are less than a away from the main subscription terminal are received. If the distance between the subscribed terminal and the main subscribing terminal is less than the value a defined by the MsgDistance, the GIS server normally transfers the position information of the subscribed terminal to the main subscribing terminal. Otherwise, it is discarded.
And secondly, the main subscription terminal normally receives the position information of other subscribed terminals, the main subscription terminal calculates the distance between the main subscription terminal and other subscribed terminals, compares the distance with the other subscribed terminals according to a set range, displays the distance within the range, and discards the other subscribed terminals.
