The dynamic assignment implementation method of user's registration information in the next generation network
Technical field
The present invention relates to communication technical field, relate in particular to the dynamic assignment implementation method of user's registration information in a kind of next generation network (NGN).
Background technology
Some communication terminal among the NGN (next generation network) can dynamic registration to the NGN network, log-on message is generally distributed to the user by operator, the user can have a plurality of log-on messages, but the general only corresponding unique user of log-on message, so that charge.But there is a class business, they are not the log-on message chargings according to caller, as the WEB800 networking telephone by freephone, or click to dial is by the card charge, use the number of users of this class business huge, distribute one and unwanted log-on message for each user with traditional method, manageability is not wasted resource.For addressing this problem, following method is arranged generally:
1, NGN network support anonymous registration, the user can not register or adopt a disclosed log-on message to register these business of using.But this mode can not be treated with a certain discrimination the identical terminal control of authority of all professional employings, and the security set rank must easily under fire, be carried out new business and can make safety problem more complicated according to the most weak service security setting.
2, different business provides different open log-on messages, can solve the problem that different business provides different security set.But sometimes because the restriction that realized by the NGN network equipment, terminal must be registered so that this terminal of unique identification with different log-on messages, and at this moment this method can't be used.
Summary of the invention
Technical problem to be solved by this invention is: overcome and do not register when existing communication terminal uses in the NGN network some professional or when adopting disclosed log-on message, the low deficiencies such as wasting log-on message that reaches of the fail safe that is brought, a kind of dynamic assignment implementation method of user's registration information is provided, thereby improves professional safety in utilization and save the log-on message resource.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
The dynamic assignment implementation method of user's registration information in this next generation network may further comprise the steps:
Log-on message pond management equipment is set in next generation network (NGN), and in this log-on message pond management equipment, disposes available log-on message resource;
When using the NGN Network, communication terminal is request registration information from the management equipment of log-on message pond, and registers this log-on message to the registrar of NGN network, or by log-on message pond management equipment agency of trademark registration;
After the registration, communication terminal communicates, and request registration information pond management equipment discharged this log-on message after communication terminal used this log-on message, and nullified this log-on message from registrar, or by log-on message pond management equipment agency cancellation, and preserve described log-on message;
When the communication terminal request registration, the communication terminal of described log-on message being distributed to the described request registration uses.
Described communication terminal is request registration information from the management equipment of log-on message pond directly, or obtains system's request registration information from the management equipment of log-on message pond indirectly by log-on message.
Log-on message in described log-on message pond management equipment and/or the registrar is provided with the term of validity, communication terminal must be before log-on message be overtime, management equipment is asked this log-on message again to the log-on message pond, and re-register, or act on behalf of when communication terminal is asked this log-on message again by log-on message pond management equipment and to register to registrar to registrar.
Behind the registration timeout, log-on message pond management equipment discharges this log-on message and uses for other users, and registrar is nullified this log-on message, or acts on behalf of when log-on message pond management equipment discharges this log-on message and nullify to registrar.
Registration management pond management equipment provides an overtime formation to deposit overtime log-on message, has only after the log-on message of idle log-on message formation distributes, and registration management pond management equipment just begins to distribute the log-on message of overtime formation; And before the log-on message of idle log-on message formation distributes, if log-on message pond management equipment has been received the request of the request registration again of overtime log-on message correspondence, this log-on message will return to user mode.
Ground preferably, this method also comprises:
Log-on message pond management equipment is verified what whether described log-on message request was sent by this communication terminal, to prevent that other user from simulating this communication terminal and sending request to log-on message pond management equipment.
In the log-on message request, adopt digital signature to carry out described checking.And
Registrar verifies that described log-on message request sent by this communication terminal, prevents that other user from simulating this communication terminal to the registrar registration or nullify.
The method of described checking log-on message request legitimacy is included in the log-on message of distribution authorization information is set, and registrar is verified the log-on message request of this communication terminal according to set authorization information.
Described log-on message comprises user ID, user cipher.
Beneficial effect of the present invention is: the present invention is directed in the NGN network, some service-user quantity is huge, for business, log-on message is nonsensical, and for the network equipment, require the contradiction of user again with different log-on message registrations, provide in a kind of NGN network service-user to share and used one group of log-on message, the implementation method of user's registration information dynamic assignment, thus not only improved the fail safe of professional use, and saved the log-on message resource, and be easy to management.
The present invention is also by setting the term of validity to log-on message, is unlikely to take the log-on message resource when preventing professional execute exception and do not put.The present invention is also by providing an overtime formation to deposit overtime log-on message in registration management pond management equipment, have only after the log-on message of idle log-on message formation distributes, registration management pond management equipment just begins to distribute the log-on message of overtime formation, reduced like this since network short-duration failure or other recoverable short-duration failures cause again the request of request registration information lose and registration timeout after, the situation that log-on message pond management system is distributed to other users with log-on message occurs.The present invention also verifies register requirement, has further improved the fail safe of professional use.

Embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
In the NGN network, communication terminal uses network function by being registered in the NGN network, and some professional customer group is huge, distributes a log-on message can not for each user, for the network equipment, requires the user to register with different log-on messages again.The present invention is for addressing the above problem, and pre-configured one group of log-on message is shared and used, and log-on message of first to file when the user uses business uses the back and discharges, and other users can use this log-on message again.The restriction that this method is not realized by the NGN network equipment.The method that employing is similar to DHCP (IP address dynamic assignment) realizes the dynamic assignment of user's registration information in the next generation network (NGN).
The present invention defines one group of available log-on message resource in the NGN network, the available log-on message resource of configuration in the management equipment of log-on message pond, this equipment both can be certain equipment that has defined in the NGN network, as soft switch, application server etc., also can be a special equipment that carries out the management of log-on message pond.When the user used business, communication terminal was asked a log-on message from the management equipment of log-on message pond, and registered this log-on message to the registrar of NGN network (or by log-on message pond management equipment agency of trademark registration).
As shown in Figure 1, log-on message obtains system can realize (promptly merging mode) in communication terminal, and communication terminal will use this log-on message to be registered on the registrar of NGN network behind the acquisition log-on message; As shown in Figure 2, log-on message obtains system also can not realize (being separate mode) in communication terminal, this moment log-on message obtain system with the log-on message that obtains by certain mode notifying communication terminal, communication terminal is registered on the registrar of NGN network again.Log-on message obtains system and communication terminal can be two softwares that move on computers, and advice method can be modes such as command line parameter, remote procedure call, ICP/IP protocol; Communication terminal also can provide the equipment that slot is expanded, and then log-on message obtains system and can be implemented in chip or the veneer, by slot notice log-on message.Communication terminal can directly not be registered on the registrar yet, and is registered on the registrar by log-on message pond management system agent communication terminal.
At this moment communication terminal can communicate, and after communication terminal used this log-on message, registrar was nullified this log-on message from NGN.As adopt separate mode, then communication terminal again request registration information pond management equipment discharge this log-on message; As adopt the merging mode, then communication terminal notice log-on message obtains system request log-on message pond management equipment and discharges this log-on message.Communication terminal can directly not nullified log-on message from the registrar of NGN yet, but is nullified to registrar by log-on message pond management agency when discharging log-on message.
For under the situation of professional execute exception, during as communication terminal deadlock, subnetwork collapse, being unlikely to take the log-on message resource does not put, can define a term of validity to log-on message, log-on message obtains system must be before log-on message be overtime, management equipment is asked this log-on message again to the log-on message pond, and to registrar re-register (or by log-on message pond management equipment when log-on message obtains system and asks this log-on message again the agency to the registrar registration).Behind the registration timeout, log-on message pond management equipment will discharge this log-on message automatically and use for other users, and registrar will be nullified this log-on message (or the agency nullifies to registrar when log-on message pond management equipment discharges this log-on message) automatically.
For reducing because network short-duration failure or other recoverable short-duration failures cause again the request of request registration information to be lost, registration timeout post-registration information pool management system is distributed to other users with log-on message.Can take following method: registration management pond management equipment provides an overtime formation to deposit overtime log-on message, have only after the log-on message of idle log-on message formation distributes, registration management pond management equipment just begins to distribute the log-on message of overtime formation; And before this, if log-on message pond management equipment has been received the request of the request registration again of overtime log-on message correspondence, this log-on message will return to user mode.
For preventing that user's simulated log-on Information Acquisition System from sending request to log-on message pond management equipment, log-on message pond management equipment will verify that asking to obtain system by log-on message sends.The method of checking can adopt but be not limited to digital signature technology.
For preventing user's simulated log-on Information Acquisition System to registrar registration or cancellation, registrar will be verified the legitimacy of request.The method of checking can adopt but be not limited to and comprise authorization information in the log-on message that distributes, and the pre-configured identical authorization information of registrar is verified the request that communication terminal is sent.
Log-on message generally comprises but is not limited to address, user ID, the user cipher (or the shared professional password of all service-users) of registrar.
Being illustrated in figure 3 as user's register flow path figure of the present invention, is example with the separate mode, is described as follows:
When 1, the user used business, communication terminal directly or by log-on message obtained system's log-on message of request from the management equipment of log-on message pond indirectly;
2, log-on message pond management equipment sends to service logic with log-on message;
3, communication terminal is registered (or by log-on message pond management equipment agency of trademark registration) to the registrar of NGN network, and after the registration, communication terminal communicates;
4, communication terminal is nullified this log-on message (or by log-on message pond management equipment agency cancellation) from registrar after using this log-on message.
5, communication terminal request registration information pond management equipment discharges this log-on message;
6, log-on message is set with the term of validity, and communication terminal must be before log-on message be overtime, and management equipment is asked this log-on message again to the log-on message pond;
7, communication terminal re-registers (or when communication terminal again ask this log-on message acted on behalf of to registrar registration by log-on message pond management equipment) to registrar;
8, log-on message overtime after, log-on message pond management equipment will discharge this log-on message automatically and use for other users;
9, registrar is nullified this log-on message (or the agency nullifies to registrar when log-on message pond management equipment discharges this log-on message) automatically.
The invention provides in a kind of NGN network service-user and share and use one group of log-on message, the implementation method of user's registration information dynamic assignment, thus not only improved the fail safe of professional use, and saved the log-on message resource, and be easy to management.
