With reference to figure 3, the calling implementation method that is used for taxi cluster group calling according to another embodiment of the present invention is described.As shown in Figure 3, this calling implementation method may further comprise the steps: after S302, group's dispatching desk received about car information of a client, dispatching desk was initiated the group calling dispatch request to the taxi group that the group scheduling district has covered this area; S304, the dispatch request that dispatching desk is initiated arrives dispatch server through the dispatch application server, and dispatch server sends the group calling authentication request to authentication server; S306, after authentication server is received the group calling authentication request, judging group according to information in the database is taxi group, returns authentication responses to dispatch server, has comprised the group informations such as dispatch service district of group type (indicating is taxi group), the ID of group and group in replying; S308, after dispatch server is received replying of authentication server, use the ID of group to carry out paging in the dispatch service district of group, set up the signaling and the voice link of the taxi terminal room in dispatch server and this group scheduling service area, set up dispatch server simultaneously and initiate signaling voice link between the dispatching desk of request; S310, after group calling was set up successfully, dispatch server was by the success of signalling path notice dispatching desk call setup, and dispatching desk loquiturs, and tells that all member somewheres have the client to need taxi in the group; After near the S312, client taxi is heard voice, tell the license number of dispatching desk oneself, carry the client to the customers' place then; S314, dispatching desk initiate to discharge group calling, and the request that discharges arrives dispatch server, dispatch server call release through the dispatch application server.
In step S302, dispatching desk is known client's particular location by client Yue Che request, therefore seeks a suitable group, and the scheduling district of this group is just in time in client's position.If there is not so idle group, then dispatching desk can be selected other any idle groups, the dispatch service district of Dynamic Selection group makes Customer Location in this dispatch service district when initiating the taxi group calling, can be controlled at very little area or bigger area and carry out the taxi group calling.The principle of selecting is distinguished in scheduling, selects little scheduling district as far as possible, if there is not idle taxi to receive scheduling this time, then discharges group calling, and dispatch in the bigger scheduling district of selection then.
Wherein, scheduling district is meant that operator divides into a plurality of zones according to network coverage situation with network coverage ground, dispatch Qu Keda, can be little.Little scheduling district can only contain a sub-district (Minimum Area unit in the wireless telecommunications), and big scheduling district can comprise a plurality of little scheduling districts.
In step S308, dispatch server only carries out paging to the taxi terminal in the group scheduling district, though therefore this taxi group comprises all taxi terminals of company, actual had only part by the taxi terminal of incoming call group calling, i.e. part in group scheduling service area position.
In step S310, after the taxi group calling is set up, dispatching desk has limit priority in group calling, he can interrupt speaking of any taxi terminal, and all the taxi terminals in the group calling can be heard the voice that dispatching desk is spoken, if but certain taxi terminal speak, his voice platform that can only be scheduled hears that other taxi terminals can not be heard so.
In step S312, know the client that can tell chauffeur behind the license number of taxi when dispatching desk.
With reference to figure 4, illustrate that the taxi cluster group calling according to the embodiment of the invention works the signaling message flow process of exhaling.As shown in Figure 4, this flow process may further comprise the steps:
S402, the dispatching desk A of certain taxi group receive that certain client's chauffeur phone, dispatching desk A learn client's particular location (such as what mansion next door on what road) from phone.Dispatching desk is selected the taxi group of a free time, and selects the scheduling district of group, and the position that makes the client is just in time in the scheduling district, or near the scheduling district.Dispatching desk is initiated the taxi group calling, and dispatching desk sends the group calling request message to the dispatch application server.
After S404, dispatch application server received the group calling request message that dispatching desk sends, the dispatch server to this locality sent the group calling request message.
S406, dispatch server receive after the message and send the group calling authentication request message to authentication server, contains the information of the dispatching desk that makes a call in the message, by essential information such as the group number of call group and by the information such as dispatch service district of call group.
After S408, authentication server receive the group calling authentication request,,, carry authorization messages such as the ID of group in the response message to dispatch server loopback group calling authentication response message to initiating dispatching desk and being carried out authentication by call group.
S410 after dispatch server is received authentication responses, sends beep-page message to dispatching desk by the dispatch application server to dispatching desk.
S412, dispatching desk sends the message that pages reply by the dispatch application server to dispatch server.
S414, dispatch server sends the GID of group beep-page message by base station sub-system all taxi terminals in the group scheduling service area.
S416, base station sub-system sends the message that pages reply to dispatch server, and taxi cluster group calling is set up successfully.
Wherein, in step S402, the method for client's chauffeur also has multiple means such as short message, network service, but all needs client oneself that the situation of own position is provided, and judges that the ways and means of Customer Location is not the problem that the present invention considers.
Wherein, in step S410 and step S414, can carry out simultaneously, not have certain sequencing the paging of dispatching desk and taxi terminal.
Wherein, in step S414, the paging of the ID of group may send repeatedly, regularly resends repeatedly such as base station system.Even if group calling rises when exhaling, some taxi is not in the scheduling district of this group calling, in case after they enter the scheduling district so, just still may enter this group calling.
Wherein, in step S416, the base station only sends the message that pages reply to dispatch server, the expression base station sub-system has been sent paging from the ID of group to the taxi terminal of corresponding area.The terminal that base station sub-system also can be got up at each paging send to dispatch server and page reply (for fast dispatch, these message some the time seem that some is unnecessary).
Wherein, dispatch server and authentication server have only carried out a step authentication, and when comparing general group calling authentication, also demand is got rapid mutual of multistep such as group member information, has saved the time greatly.
The scheduling district of selecting when dispatching desk makes a call is too small, do not have in the scheduling district free time seek the place far way from home taxi can situation for client's use under, dispatching desk can finish this time to call out, and initiates a scheduling district again and makes a call in the zone relatively biglyyer, thereby effectively taxi is dispatched.
Fig. 5 is the scene schematic diagram of the embodiment of the invention.The client is to the dispatching desk chauffeur among the figure, dispatching desk has been initiated the taxi cluster group calling as the scheduling district of figure, b among the figure, c, d, if these 4 taxi free time of e all can be inserted in this group calling, a taxi among them can be accepted the chauffeur request, tell dispatching desk with the license number of oneself, dispatching desk can be notified the client.Though taxi a is also closer from the client among the figure, because, do not insert and call out, so the client is arranged near not knowing not in the scheduling district.
In sum, the present invention has proposed a kind of taxi cluster group calling method that realizes under to the immovable prerequisite of existing digit group system network configuration in trunking communication, improved the efficient of taxi dispatching greatly.
The method that realizes taxi dispatching in digital cluster system can also have various deformation, only discloses the minority realization here.Yet should be appreciated that not deviating under the prerequisite of the present invention and can make various changes and reinforcement, and these changes and strengthen all being comprised in protection scope of the present invention.
The above is embodiments of the invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
