Embodiment
Below in conjunction with accompanying drawing, will be described in detail each preferred embodiment of the present invention.
Shortcoming at the current cluster system exists the present invention proposes a kind of solution preferably, has promptly proposed the notion of virtual scheduling server and virtual base station subsystem on the basis of the hardware that does not change group system and the network architecture.
Realize the method for roaming control and roam charge in a kind of group system provided by the present invention, serve the roaming that effectively to control cluster user under a plurality of areas or the city situation a group system, this system comprises base station sub-system, trunking dispatching subsystem, above-mentioned base station sub-system links to each other with trunking dispatching subsystem, and wherein: above-mentioned base station sub-system further comprises base station controller, base station transceiver, dispatching client equipment; Above-mentioned trunking dispatching subsystem further comprises dispatch server, authentication server; Wherein dispatch server is finished the forwarding of trunked call service relevant treatment and voice; Authentication server is finished the cluster client and is comprised the user, group, and the registration of group etc. and related service, Authentication Authorization and charging, authentication server comprises the cluster customer database.
Above-mentioned base station sub-system disposes different base station sub-system signs respectively by the difference of location; Above-mentioned dispatch server is at the different a plurality of virtual regional dispatch server sign of each different base station sub-systems configuration, a configured list is arranged in the dispatch server, and the virtual scheduling server identification carries out corresponding one by one with the base station sub-system sign in this configured list; A dispatch server sign or a base station sub-system have identified an area or city.Each colony terminal all has and only has a home zone, an ownership dispatch server sign.This ownership dispatch server identification information storage is in the cluster user database of authentication server.
The handling process of the location update message of the terminal that has shown the inventive method roaming as shown in Figure 3 or do not roamed, its step below is elaborated:
Step 301: the location update message that this area terminal is sent is received in the base station, and this message is passed to dispatch server;
Step 302: dispatch server such as the IP address of DC in the base station system, finds out corresponding dispatch server sign according to the sign of the base station sub-system in the message in the dispatch server identification list;
Step 303: dispatch server is processed as the location update message of issuing authentication server together with message of receiving and the dispatch server that inquires sign, and location update message is sent to authentication server;
Step 304: authentication server is received location update message, obtains the current authentication server sign in the location update message, and query set group user's data storehouse obtains the ownership dispatch server sign of terminal simultaneously;
Step 305: whether the ownership dispatch server sign of comparison terminal is identical with current authentication server sign.If it is identical then determine this terminal in its service area, execution in step 308; Otherwise judge further whether this terminal has roaming capacity, execution in step 306.
Step 306: whether authentication server is inquired about this terminal in its database have roaming capacity.If do not have roaming capacity then execution in step 307, otherwise execution in step 308.
Step 307: authentication server is changed to out of reach with SOT state of termination in database, and answers to the dispatch server response, carries corresponding error code in replying, and replys through dispatch server base station, last incoming terminal.Execution in step 309.
Step 308: authentication server is changed to SOT state of termination at service area in database, and carries out the normal position and upgrade processing, responds to dispatch server and answers, and replys through dispatch server base station, last incoming terminal.Flow process finishes.
Step 309: show out of reach on the terminal.Flow process finishes.
In described step 308,, can not need again SOT state of termination to be changed at service area so if the original state of terminal is exactly at service area in the database.Otherwise then must put, because some situation must be considered, can not roam such as terminal, terminal has arrived the other places so, his state in authentication server is exactly an out of reach so, if but terminal then must be changed to terminal at service area, so that terminal can normally be carried out various group services when ownership place is got back in the other places.
After the processing through above-mentioned position renewal, if but terminal does not have roaming capacity roamed, the state of terminal in the database of authentication server just become out of reach so.When if terminal produces various group service like this, just can be rejected.No matter the feasible terminal that can roam of processing simultaneously can both normally carry out the position under the situation of roaming and not roaming upgrades, and does not influence the state of terminal.
Note, above example in only illustrated that all terminal can roam situation about maybe can not roam, in fact operator's roaming condition of control terminal more neatly, such as 3 signs are arranged in the dispatch server identification list that disposes in the dispatch server, be that this group system is served 3 areas, one of them is the ownership place of terminal, operator can roam in 2 areas by configurating terminal so, can not roam (being its home service district) at another, utilize the inventive method to control easily so, just the manner of comparison in 305 steps in Fig. 3 flow process is changed, wherein ownership dispatch server sign is changed to a tabulation, contains two dispatch servers signs that terminal can roam in the tabulation and gets final product.
To sum up, the inventive method just is easy to realize to the control of the group service of terminal under roaming state, and the situation below in conjunction with Fig. 4 and Fig. 5 illustrate individual calling and group calling respectively illustrates simultaneously the processing procedure that roaming terminal charges in the lump.
As shown in Figure 4 for having increased the situation of roaming control and realizing the cluster individual calling of roam charge.
Step 401: the individual calling message that terminal is initiated is through the base station, and dispatch server arrives authentication server;
Step 402: authentication server carries out the individual calling authentication, and checks that whether the calling and called terminal is all at service area in the database;
Step 403: if having an out of reach in the calling and called at least, execution in step 404 so, otherwise execution in step 405.
Step 404: authentication server returns the authentication message that rejects response to dispatch server, replys through dispatch server base station, last incoming terminal.Execution in step 407.
Step 405: authentication server returns authentication by response message to dispatch server, and dispatch server inserts calling and called in the trunked call by the base station.Execution in step 406.
Step 406: behind the end of calling, dispatch server sends charging message to authentication server, has carried the current separately on-site dispatch server sign of calling and called in the message.The individual calling flow process finishes.
Step 407: show Calls failure on the calling terminal.The individual calling flow process finishes.
In described step 401, if the calling terminal out of reach, because terminal oneself would know own out of reach, so also can terminal oneself just refuse that the user makes a call or carry out other group service.In described step 406, in the charging message during carried terminal generation cluster individual calling purpose of on-site dispatch server sign be, the area at place was convenient to operator and is carried out accurately and flexibly chargeing when follow-up charging tent treatment system can know that terminal is used group service by this dispatch server sign.
As among Fig. 5 being the situation that has increased roaming control and realized the cluster multi call of roam charge.With Fig. 5 and Fig. 4 relatively, can find the step basically identical, just some is different for the situation of step 504 and individual calling, when cluster multi call, caller must be at service area, and this is the same with individual calling, as long as but other member in the group has an above state is that group calling will be successful so at service area.
Other group service of the inventive method is such as management and group, whether supplementary service or the like can come terminal is roamed control at the state of service area in the database of authentication server by judging terminal, when the terminal out of reach, refusal provides cluster service to terminal.
Be illustrated in figure 2 as and realize logical schematic of the present invention, the shared group system in Suzhou and Nanjing wherein, the Suzhou base station sub-system has comprised the BTS of all Suzhou District among the figure, BSC and DC, equally, the Nanjing base station sub-system has comprised BTS, BSC and the DC in all areas, Nanjing.
At the still original dispatch server equipment physically of the dispatch server shown in Fig. 2, but by virtual be two virtual scheduling servers, i.e. Nanjing dispatch server and Suzhou dispatch server.Base station sub-system also is divided into two systems in Nanjing and Suzhou according to responsible area simultaneously.Disposed a dispatch server identification list on the dispatch server, contained all base station sub-system signs of a plurality of dispatch server signs and its correspondence in the tabulation, expression Suzhou during wherein dispatch server identifies, an expression Nanjing.Wherein Nanjing is represented for one in expression Suzhou in the base station sub-system sign.Described base station sub-system sign can be the IP address of DC.The corresponding Suzhou of Suzhou dispatch server base station sub-system wherein, the corresponding Nanjing of Nanjing dispatch server base station sub-system.
Authentication server physically still is an original authentication server equipment among Fig. 2.It has comprised the cluster user database, and all in the cluster user database of authentication server, in order to realize the inventive method, each user has disposed the ownership dispatch server sign of oneself to the information of each cluster user in this cluster user database.If have only two the dispatch server signs in Nanjing and Suzhou in the system, user's ownership dispatch server identifies or is Nanjing so, or is Suzhou.When user attaching dispatch server sign was Nanjing, the expression user was the Nanjing user.If this user has arrived Suzhou District, this user is in roaming state exactly so.
The inventive method is by increasing attribute in the location update message that sends to authentication server at dispatch server, thereby make authentication server judge terminal whether in roaming, and according to terminal whether have roaming capacity with SOT state of termination in the database be changed to or out of reach.When terminal further produced relevant group service, when carrying out authentication on authentication server, whether authentication server just can make corresponding authentication at service area according to terminal was handled.
In addition when terminal in when roaming, call out if terminal produces, authentication server can increase attribute in original charging request, thereby can make group system know the roaming condition of terminal, and operator can be chargeed to the user exactly.Be elaborated below in conjunction with embodiment, processing and relevant charging process in the change of location update message and processing, individual calling, the group calling are described.
Because when trans-regional, terminal will inevitably send location update message at once, terminal timed sending location update message periodically in addition, so the present invention has realized the roaming condition of control terminal by location update message.
In sum, the present invention proposes a kind of in trunked communication system control terminal roaming capacity and carry out the method for roam charge, effectively guaranteed control and the income of operator to the user.
Should be understood that above-mentioned description at specific embodiment is comparatively detailed, can not therefore be interpreted as the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with claims.
