PDS is the master control point of trunked call, finishes the processing of colony dispatching calling etc.; PDS also receives the cluster speech data from reverse link, is distributed to corresponding forward link again according to the character of calling out; PDS can be used as PPC, to PPS report user's prepayment capabilities, is responsible for the application of user's quota, the monitoring Quota Usage, and also operable independent equipment is as PPC.

PHR preserves the log-on message and the positional information of cluster user and group, realizes authentication, mandate and charging to cluster user, and the position is upgraded and group management function; PHR can be used as PPS, is responsible for differentiating prepaid user's account status to the Service Control Point request, and the premium-paid plan of selecting this session to use according to the prepayment capabilities of PPC, also operable independent equipment is as PPS.

DAS is responsible for safeguarding the session of each dispatching desk, turnkey console, realizes turnkey console and dispatching desk administering and maintaining colony dispatching.

DAC comprises dispatching desk and turnkey console, and dispatching desk is realized comprising and made a call query State, functions such as recording; Turnkey console is carried out the division to group, bookkeepings such as user right.

PHRAgent can directly manage group, group and user, as distributing authority etc.

SCP4 is responsible for preserving prepaid user's accounts information and rate handover information, possesses the rate scaling function, can the different exchange rate be set according to the group service type.

At present, in the existing prepayment service in the communications field, calling for prepaid user's initiation, after the success of PHR authentication, PDS directly reports SCP to user's calling, and SCP judges whether the user also has remaining sum, and the result according to the remaining sum application judges whether calling user then, the prepaid user's call mechanism that relates among patent CN200610160609 and the US6044247 all is this implementation, and this mode has influenced user's access speed greatly.

Summary of the invention

The technical problem to be solved in the present invention is, prepaid user at digital cluster system in the prior art calls out the slow shortcoming of access speed, the method of in a kind of digital cluster system the prepaid user being carried out paging control is provided, and this method can effectively improve the access speed of prepaid call.

In the digital cluster system of the present invention the prepaid user is carried out the method for paging control, comprise PDS, PHR, SCP in the digital cluster system, cluster prepaid users makes a call, PDS receives and calls out the back to the PHR authentication request that makes a call, after the authentication success, PHR is to PDS return authorization information, and after PDS received authorization message, system carried out following steps:

Step 1:PDS judges at first whether this prepaid user's account has remaining sum, if judged result is for being, then execution in step 2 and step 3 simultaneously are if judged result is for denying that then execution in step 3;

Step 2:PDS initiates paging for this prepaid user;

Step 3:PDS sends the pre-payment request to PHR;

After step 4:PHR receives the pre-payment request of PDS, be initiated as the request of prepaid user's quota application to SCP;

Step 5:SCP is responsible for checking whether this user account has legal state and remaining sum, if testing result for being, then is these prepaid user's allocated quotas, simultaneously the quota application success message is returned to PHR; If check result then directly returns to the quota application failed message PHR for not;

Step 6: if SCP returns quota application success, then PHR notice PDS continues as this prepaid user and normally continues, if SCP returns the quota application failure, then PHR notice PDS forbids that this prepaid user inserts calling; When described service control point returns the quota application failure, be continuously this prepaid user if system has carried out described step 2 and initiate paging, then dispatch server stops this prepaid user of paging; When described service control point returned the quota application failure, if system has responded described step 2 and made this prepaid user insert calling, then dispatch server forced to discharge this prepaid user;
