Description

Communication method, device and storage medium based on position information change

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication method, device, and storage medium based on location information change.

Background

A Global System for Mobile Communications-Railway (GSM-R) is specially used for daily operation management of railways, is suitable for Railway communication, particularly for the requirement of Railway special scheduling communication, and mainly provides voice communication functions such as wireless train dispatching, marshalling shunting communication, section maintenance and maintenance operation communication, emergency communication, tunnel communication and the like.

Location addressing is an advanced addressing technology in GSM-R, and is a key technology and necessary means for implementing trunking dispatch communication, and its process is that a call for a specific function, which is generally initiated by a mobile user (such as a train conductor, etc.), is routed to a destination address related to the current user/train location. For example, when a train arrives at a station, the intelligent network calls the current dispatcher, broadcaster and the like according to the position information of the train mobile station by dialing the corresponding short number, so that the train can be dispatched to the station, broadcast to the station, and instruct the administrator to close the passage when the train is about to arrive at the intersection of the railway and the urban road.

In the location addressing scheme, when a train arrives at a fixed area (such as when the train arrives at a station and passes through an urban road intersection), a short number needs to be dialed by a train operator operation terminal, a dispatcher is informed of the train arriving at the station, and a manager of a railway and the urban road intersection is informed of closing a ramp. In the addressing process, the trainee operating terminal is required to dial fixed short numbers one by one. This addressing scheme suffers from the following disadvantages:

1. train personnel need to continuously confirm the current position information of the train;

2. the possibility of wrong dialing and testing exists when the train crew dials the number;

3. the possibility that the train personnel are tired of misoperation or forget to operate exists;

4. in the actual running process of the train, the conditions of an adversary such as late time, way giving for other trains and the like may occur, and the position information of the train needs to be continuously confirmed by a manager of the train mobile station to know the current position information and confirm whether to initiate a corresponding call.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

First embodiment

As shown in fig. 1, a preferred embodiment of the present invention provides a communication method based on location information change, which is applied to a Mobile Station (MS), and the method includes the steps of:

a location-addressed call request is made to a master mobile call center (Anchor MSC) at a first location, step 101.

Specifically, a location-addressed call is initiated at a first location, namely: dialing a short number at the current location, sending a SetUp message to a Base Station Subsystem (BSS), and the BSS forwarding the message to an Anchor Mobile call center (MSC). In the present embodiment, the in-vehicle terminal may be a terminal in which a change in positional information occurs, such as a train or a car.

Further, the calling number may be a train number of the vehicle-mounted terminal, or a combination of the train number and the service type, and the embodiment is not particularly limited.

Further, after step 101, the method may further include the steps of:

and establishing a first communication connection of a first called party corresponding to the first position.

Specifically, the first position may be understood as an initial position of the MS, such as: the train's origin, accordingly, the first called party can be understood as a calling party at the initial location, for example: a dispatcher at the originating station. The MS is the calling party and the first called party is the called party. That is, the MS communicates with the scheduling terminal at the initial location to facilitate the scheduler to communicate information such as the train origination time with the conductor on the train.

Step 102, the detection position moves from the first position to a new position.

In the present embodiment, the positional change means: location within the same BSS. In other embodiments, the change in position may also refer to: location changes resulting from handover in different BSSs.

Step 103, retrieving a second location associated with the new location according to a Service Control Point (SCP), and establishing a communication connection between the called parties corresponding to the second location.

Specifically, a communication connection is established between the called party corresponding to the second position, so that a conductor on the MS can communicate with a dispatcher at the second position, and the dispatcher can obtain the current position of the MS immediately to prepare for the train to get in.

Further, when the SCP retrieves the second location associated with the new location, the method further comprises:

disconnecting the first communication connection with the first called party.

Further, as shown in fig. 2, step 103 specifically includes:

step 201, receiving the information of the second called party sent by the Anchor MSC;

step 202, when the second called party answers, the second called party is communicated with.

In the above step, if the called party corresponding to the second location is the second called party, the information of the second called party sent by the Anchor MSC is received. When the second called party answers, the MS and the second called party are connected, and the MS and the second called party are enabled to carry out conversation.

In this embodiment, if there are two or more second called parties, each second called party is independent and reports the DP event separately, using the principle that whose response message is received first reports whose event.

Further, in practical application, a situation that a train running train belongs to a plurality of MSCs for management may occur, and there are scenes such as changes of location information between offices, for example, data services, and the like, so that reporting of a new location may be implemented by using the prior art, and this embodiment is not described in detail again.

In the communication method based on the position information change, the addressing call request is sent to the Anchor MSC at the first position, the detection position is moved from the first position to the new position, the second position associated with the new position is retrieved according to the service control point SCP, and the communication connection between the called parties corresponding to the second position is established, so that the whole process is completely automated, manual interference is not needed, and the efficiency and the accuracy are greatly improved.

Second embodiment

As shown in fig. 3, a second embodiment of the present invention further provides a communication method based on location information change, which is applied to a Mobile Services Switching center (Anchor MSC), and the method includes the following steps:

an addressed call request sent by the MS at a first location is received, step 301.

Specifically, the MS initiates a location-addressed call, namely: dialing a short number at the current position, sending a SetUp message to a Base Station Subsystem (BSS), and forwarding the message to the Anchor MSC by the BSS. In this embodiment, the MS may be a terminal in which a change in location information occurs in a train, a car, or the like.

Step 302, according to the addressing call request, when detecting the location change of the MS, sends the new location to the SCP.

Specifically, the addressing call request is received, and number analysis is performed to analyze that the current service is an automatic location addressing service. More specifically, the Anchor MSC analyzes an entry according to the number of the originating call, finds all indexes configured for the entry, performs number matching from left to right, and obtains a number analysis result corresponding to the index after the number matching is successful, wherein the number analysis result has a corresponding service type which is a location addressing service. According to the current service type, sending IDP message to SCP, the IDP message carries the parameters of MS dialing short number, MS position information, service key, etc.

During the running process of the train or the automobile, the position is changed, such as: and when the terminal enters a position area where the intersection of the urban road and the railway is located, the terminal is switched, and the Anchor MSC is notified through a switching confirmation message.

After receiving the switching confirmation message, updating the position information of the terminal, and reporting the detection event of 'position change' to the SCP, wherein the reported event carries the latest position information.

Step 303, receiving the second location associated with the new location and retrieved by the SCP.

Specifically, the SCP pre-establishes the association information between the location information where the train number route passes and the destination address such as the dispatcher and the sub-dispatcher.

SCP obtains called number, position information and service key from received IDP message, SCP judges current automatic position addressing service according to service key, thus entering into automatic position addressing mode, then according to called number and position area information, index to current position area destination address.

Step 304, establishing a communication connection between the MS and the called party corresponding to the second location.

Specifically, a communication connection is established between the MS and a called party corresponding to the second position, so that a conductor on the MS can communicate with a dispatcher at the second position, and the dispatcher can obtain the current position of the MS immediately to prepare for the train to enter the station.

Step 305, determining whether the second position is an end position, if yes, entering step 306, and if no, returning to step 302.

And step 306, after the call is finished, ending the call.

Specifically, if the second location is the destination location and the train or car of the MS is about to enter the station, it indicates that the call between the MS and the called party corresponding to the second location is the last call, and after the call is ended, the call may be ended and the procedure may be completed.

If the second location is not the end location, it indicates that the call between the MS and the called party corresponding to the second location is not the last call, and after the call is ended, the conductor on the train still needs to communicate with the dispatcher at the next station, so that it is necessary to continue to detect the change of the location information of the MS, and repeat the above-mentioned procedure.

Further, referring to fig. 4, step 303 further includes:

step 401, receiving a notification sent by the SCP to disconnect the first communication connection when the SCP retrieves the second location associated with the new location.

Specifically, in order for the MS to communicate with a called party (hereinafter, referred to as a second called party) corresponding to the second location, the MS is required to disconnect the communication connection with the first called party. More specifically, the SCP sends a notification to disconnect the first communication connection, and instructs the Anchor MSC to release the first communication connection, and only the calling party at the MS side is reserved.

Step 402, disconnecting the first communication connection and sending a response to the SCP to release the first communication connection.

Specifically, a notification sent by the SCP to disconnect the first communication connection is received, the first communication connection is released, and a response for releasing the first communication connection is sent to the SCP to notify the SCP that the first called party has been successfully deleted.

Step 403, receiving a notification sent by the SCP to call the second called party.

Specifically, after receiving the response of releasing the first communication connection, the SCP issues a Request Report BCSM Event (RRBE) message to monitor the location change condition of the MS. Meanwhile, according to the number of the second called parties, an ica (initial Call attach) message is sent to the Anchor MSC to instruct the Anchor MSC to set up the second called party in a corresponding calling party (Call Segment, CS) for the dispatcher. In this embodiment, the ICA message is a message sent by the SCP to the Anchor MSC, and the message carries information such as a called number and a calling number, and the Anchor MSC is requested to establish a call through the message.

Alternatively, if the second called party is two, such as: dispatcher and vice dispatcher, SCP sends 2 ICA messages to the down part of Anchor MSC to instruct Anchor MSC to set up a second called party in CS2 for dispatcher, then sets up another second called party in CS3 for vice dispatcher, and sets up calls to dispatcher and vice dispatcher in the following steps.

Further, referring to fig. 5, step 304 further includes:

step 501, according to the notification of calling the second called party, establishing a call request to the second called party.

Specifically, after receiving the ICA message, a response message of the ICA is returned to the SCP. In this embodiment, after receiving the ICA message, the authority check needs to be performed, and after passing the check, the response message of the ICA is returned to the SCP. After the SCP receives the response message of the ICA, a call notification is sent to the Anchor MSC for each second called party, where the call notification in this embodiment is an RRBE message and a CWA (Continue With parameter) message, where the RRBE message is used to monitor MS location information, and the CWA message is used to instruct the Anchor MSC to establish a call to the second called party.

Further, referring to fig. 6, step 501 further includes:

step 601, according to the call notification, configuring the DP point of the second called party in the call establishment process.

Specifically, after receiving the RRBE and CWA messages, the Anchor MSC needs to configure a Detection Point (DP) of the second called party call setup process, and the DP is monitored by the SCP, for example: DP such as O-Answer and O-Disconnect.

Step 602, a call is established to the called number carried in the call request by using the locally configured calling number selection.

Specifically, the locally configured ICA call number analysis selection is adopted to only perform number analysis on the called number carried in the ICA message, so as to obtain the service type of the call, and finally, the call of the second called party is established according to the service type obtained by the number analysis.

Step 502, when the second called party accepts the call request, receiving a response message sent by the second called party.

Specifically, when the MS initiates a call, the second called party generates a ring response, and receives a response message sent by the second called party when the call is connected.

And 503, reporting the DP event to the SCP when a detection point DP is monitored.

Specifically, after receiving the response message of the second called party, monitoring a DP event (for example, an O-Answer event) in an RRBE message sent by the SCP, sending an erb (event Report bcsm) message to the SCP, and reporting the DP event (for example, the O-Answer event).

Step 504, receiving the request of the mobile calling party sent by the SCP according to the DP event.

Specifically, the DP event is taken as an O-Answer event as an example. The SCP receives the O-Answer event and sends a request for a mobile Leg to the Anchor MSC to move each second called party to the CS corresponding to the MS.

Further, if there are two or more second called parties, each second called party is independent and sends the request of the mobile calling party respectively.

Step 505, according to the request of the mobile calling party, the information of the second called party is moved to the calling party corresponding to the MS, and when the second called party answers, the MS and the second called party are enabled to communicate.

Specifically, after receiving the request of the mobile calling party, the information of each second called party is moved to the CS corresponding to the MS, the terminal of each second called party is moved to the context where the MS is located, and after the movement is successful, the response of the mobile calling party is sent to the SCP. Meanwhile, sending ringing and response message to MS to connect MS and the second called party to make MS and the second called party talk.

Further, after the call is finished, the second called party hangs up and sends a release message to the Anchor MSC, and after receiving the message, the Anchor MSC reports a hang-up event to the SCP to inform the SCP that the call is released.

In this embodiment, the location change of the MS means: the location of the MS in the same BSS changes. In other embodiments, the change in location of the MS may also refer to: the MS performs handover in different BSSs resulting in location change.

Referring to fig. 7, when the MS is handed over in different BSSs, step 302 further includes:

step 701, detecting that the MS is switched from a first BSS to a second BSS.

Step 702, receiving a handover request sent by the first BSS.

Step 703, forwarding the handover request to the second BSS.

Step 704, when the second BSS sends a handover response to the MS and the MS is handed over to the second BSS, receiving a message that the handover is successful, which is sent by the second BSS.

Step 705, according to the message that the handover is successful, updating the location information of the MS, releasing the first BSS, and reporting the new location of the MS to the SCP.

Further, after step 705, the communication connection between the MS and the called party corresponding to the new location may be established according to the above method, and for the same contents, the details are not described herein again.

The communication method based on the position information change receives an addressing call request sent by an MS at a first position, sends a new position to an SCP when detecting the position change sent by the MS according to the addressing call request, receives a second position which is sent by the SCP and is associated with the new position, and establishes communication connection between the MS and a called party corresponding to the second position, so that the whole process is completely automated, manual interference is not needed, and the efficiency and the accuracy are greatly improved.
