Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The method that realizes group calling between multi-locomotive provided by the present invention realizes based on existing LTE-R locomotive platform.In the present invention, VGCS (Voice Group Call Service, voice group call service) is applied in the voice communication between railway multi-locomotive.In the process of whole multi-locomotive group calling, from heavy joint group, set up, call out to release, trainman only need carry out simple input operation at the line module of locomotive platform, just can weigh the group calling of joint group.Utilize method provided by the present invention, the staff of locomotive does not need to carry out complicated specialty operation, can effectively reduce speech business complexity.
The method that realizes group calling between multi-locomotive provided by the present invention comprises and heavily joins that the heavy joint group of group registrations is called out and heavy joint group is nullified three processes, is specifically described respectively below.
The process of the heavy joint group registration of paper.When determining, need to weigh after the locomotive of joint group, the locomotive platform on locomotive, to POC(Push-to-talk over Cellular, also claims PTT) server sends the log-on message of heavy joint group, and POC server is set up corresponding heavy joint group according to log-on message.After foundation to be grouped, POC server sends to the locomotive of registration the response message that comprises heavy joint group group catchword.Fig. 1 flow chart of joint group locomotive to POC server registration of attaching most importance to.
Step 101, inputs information such as " main control computer license numbers " and " this engine number " at the line module of master control locomotive locomotive platform, and the request of master control locomotive using this information as application marshalling is sent to POC server." main control computer license number " that wherein master control locomotive is corresponding is identical with " this engine number ".
Step 102, POC server receives the request of the application marshalling of master control locomotive, and sets up heavy joint group according to marshalling solicited message.When POC server is processed the marshalling solicited message of master control locomotive transmission, need " main control computer license number " and " this engine number " field in information extraction.POC server is set up heavy joint group according to " main control computer license number " field in solicited message, and this field is wailed as the group of this heavy joint group simultaneously.The member that this group is wailed for heavy joint group makes a call.After heavy joint group is set up, " this engine number " information of master control locomotive is deposited in this heavy joint group, as the member of this heavy joint group.After master control locomotive has been registered, POC server can send the response message succeeding in registration to master control locomotive.Wherein in this response message, need the group of carrying this heavy joint group to wail.
Step 103, slave controller car sends the request of application marshalling to POC server.Slave controller car, by locomotive platform line module, is inputted " main control computer license number " and " this engine number ", and the application marshalling that comprises " main control computer license number " and " this engine number " field to POC server transmission is asked.
Step 104, POC server receives the application marshalling request of slave controller car, and inquires according to " main control computer license number " in request the heavy joint group that this " main control computer license number " is corresponding.To be checked after this heavy joint group, POC server deposits " this engine number " information of slave controller car in this heavy joint group in.Slave controller car successfully adds after corresponding heavy joint group, and POC server sends the successfully response message of marshalling to the locomotive platform of slave controller car, and this response message need carry equally the group of this heavy joint group and wail.
The process of establishing of the actual joint group of attaching most importance to of registration process of locomotive.The present invention is when setting up heavy joint group, and first the sign of the group using main control computer license number as this heavy joint group, adds master control locomotive in this heavy joint group.Secondly, because slave controller car carries group sign, POC server inquires corresponding heavy joint group according to this group sign, and slave controller car is joined in this heavy joint group.Master control, slave controller car add after heavy joint group, and this heavy joint group can successfully be set up.In whole heavy joint group process of establishing, the staff of master control locomotive and slave controller car does not need to carry out complicated operation.When needs heavily join grouping, user only need can complete engine number input information the registration of heavy joint group.
After the locomotive that need to heavily join has been registered to POC server, between the locomotive of heavy joint group, can call out.When heavy joint group is called out, during due to heavy joint group registration, determined the group catchword of this group.Member in group need wail and make a call to POC server according to this group.When POC server is processed this calling, according to other members in the heavy joint group of the inquiry of this call information, and make a call to other members.If other members successfully accept this calling, represent can carry out push-to-talk in heavy joint group.At this moment having the driver of speech demand can pin PTT key has conversed.Referring to the flow chart of calling out between heavy joint group locomotive in Fig. 2, it comprises the steps:
Step 201, has the locomotive of voice call demand to make a call to POC server in heavy joint group.When making a call, the group of returning when locomotive meeting basis succeeds in registration is wailed, and to POC server, makes a call.
Step 202, POC server receives after the calling of locomotive, and applies for VGCS group call resource.If after applying for successfully, to caller locomotive platform, return to the response message of call setup.
Step 203, POC server is searched other member of this heavy joint group according to the engine number of caller locomotive, and makes a call to other member of this heavy joint group.
Step 203, sends the response message of call accepted to POC server as called other member of heavy joint group.
Step 204, has the trainman of speech demand to press the PTT key application right of speech of locomotive platform, and starts to talk.
Step 205, after the trainman of application right of speech has talked, unclamps PTT key release speech right.
From the above, the process of calling adopts dialing equally, then by PTT key, converses, and the method for calling between heavy joint group locomotive is similar to traditional method of calling.For the staff of locomotive, operation is comparatively simple.After calling completes, when the locomotive of heavy joint group need to finish this heavy joint group, need send the information that marshalling discharges to POC server.Due to when heavy joint group is registered, POC server is by setting up locomotive " this engine number " heavy joint group.The process that heavy joint group is nullified is similar.POC server, according to " this engine number " field in marshalling release information, exits this locomotive from heavy joint group, and returns and discharge successful response message to locomotive.The log off procedure of whole heavy joint group completes.Fig. 3 flow chart that joint group locomotive is nullified to POC server of attaching most importance to.
Step 301, after heavy joint group finishes, the locomotive platform of this group sends to POC server the request that the heavy joint group of application discharges, and in the request that the heavy joint group of application discharges, needs to carry " this engine number " field.
Step 302, " this engine number " that POC server carries according to heavy joint group releasing request exits corresponding locomotive, and returns to release successful information to the locomotive that sends releasing request in heavy joint group.After all member persons of heavy joint group exit, POC server discharges the shared VGCS resource all about this heavy joint group, and the log off procedure of heavy joint group finishes.
In sum, when heavily binding group of needs, master control locomotive and slave controller car are inputted corresponding engine number information at line module, and POC server can complete between heavy joint group foundation, group and call out and three processes of heavy joint group release according to engine number.In the foundation of heavy joint group, when discharging, trainman only need carry out shirtsleeve operation at the line module of locomotive platform, does not need to carry out the complicated operations such as frequency of writing, and can effectively improve the operating efficiency that weighs joint group.And while calling out between organizing, the present invention and traditional calling mode are to be consistent, trainman is easy to grasp.With respect to prior art, the present invention for multi-locomotive marshalling, not only reduces trainman's business complexity by VGCS method of calling, has guaranteed the ease for operation of group calling; Also without adopting multi-locomotive marshalling dedicated voice communication equipment, effectively reduce equipment redundancy simultaneously.
To realizing the method for group calling between multi-locomotive provided by the present invention, have been described in detail above.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention, it being done, all will form infringement of patent right of the present invention, will bear corresponding legal liabilities.
