Definitions
- the invention relates to a method and device for implementing a gatekeeper in an IP telephone, and in particular, to a method for implementing a gatekeeper system composed of multiple single gatekeepers and a gatekeeper system thereof.
- the gatekeeper is implemented by pure software.
- the gatekeeper generally runs on a high-performance computer system.
- the operating system used can be Windows or Unix.
- Such a gatekeeper is responsible for the multiple gateway systems under its jurisdiction, and provides these gateway systems with functions such as bandwidth management, access control, address resolution, and area management.
- the gatekeeper consumes certain resources for control. Therefore, the gatekeeper is limited by a certain capacity.
- most gatekeeper software is designed on a single computer system, and the capacity of the system is limited. At the same time, once this gatekeeper stops service due to a failure, it will affect all calls registered to the gateway and cause a serious service accident. Therefore, providing an alternative gatekeeper is an important means to improve system reliability. Summary of the Invention
- An object of the present invention is to provide an implementation method of an IP telephone gatekeeper system that can break through the capacity limitation caused by a single gatekeeper networking, and can improve system reliability, and has the functions of mutual backup and mutual replacement.
- Another object of the present invention is to provide a gatekeeper system for implementing the method for forming a gatekeeper system.
- the method for implementing the IP telephone gatekeeper system of the present invention is to connect two or more single gatekeepers to form a replaceable one, back up each other, and make the controlled gateway see one.
- the overall gatekeeper group mainly includes the following steps:
- the gatekeeper system according to the present invention is composed of two or more single gatekeeper connections, which can be replaced with each other, backed up to each other, so that the controlled gateways can see the whole. Gatekeeper Group.
- the present invention adopts a method of organically connecting a plurality of gatekeepers to form a gatekeeper group, the data capacity of the entire gatekeeper group is effectively increased through the joint cooperation of each gatekeeper, and the capacity limitation caused by a single gatekeeper in the network is broken.
- the data of each gatekeeper is dynamically synchronized to other gatekeepers in the gatekeeper group, to avoid wasting the network bandwidth by transmitting the entire data, and to enable each gatekeeper to achieve the functions of backup and replacement, so that it will not
- a gatekeeper fails to stop the service and affects all the calls registered to the gateway, which greatly improves the reliability of the gatekeeper system.
- the entire gatekeeper system uses a unified domain name, so that the controlled gateway sees only the existence of an overall gatekeeper, and translates the unified domain name of the gatekeeper group into the network transmission addresses of multiple gatekeepers through the domain name resolution system.
- Realize automatic switchover of gatekeepers so that the gateway can obtain the transmission address list of multiple gatekeepers through the domain name resolution system, ensure that the gateway can select a gatekeeper with the highest priority to issue GR0 (gatekeeper request), and can choose the load according to the load situation
- GR0 gatekeeper request
- the lower gatekeeper issues an RRQ (Registration Application), so that it can not only achieve the mapping from a single gatekeeper name of the gatekeeper group to multiple gatekeepers in the gatekeeper group, but also realize smooth expansion and reduction of the gatekeeper group.
- RRQ Registered Application
- FIG. 1 is a schematic diagram of the composition of the present invention
- the present invention is composed of two or more single gatekeeper connections, which can be replaced with each other and backed up each other, so that the controlled gateway sees an entire gatekeeper group, so that subordinate gatekeepers No matter which gatekeeper is logged in to the gatekeeper group, the gateway will achieve the same effect.
- the gatekeepers of the aforementioned gatekeeper group are formed as a whole by adopting a method of two-to-two interconnected full-interconnection network connection.
- the implementation method of the IP telephone gatekeeper system according to the present invention is to connect two or more single gatekeepers to form a single gatekeeper group that can be replaced with each other and backed up, so that the controlled gateway can see the entire gatekeeper group. It includes the following steps:
- the synchronization measures captured in the above step 1 mainly include the following steps:
- the gatekeepers forming the gatekeeper group are formed into a network connection by a fully interconnected method, wherein the fully interconnected connection method is to interconnect each gatekeeper in pairs;
- the synchronization data protocol involved in the present invention mainly includes a gatekeeper status synchronization protocol, a data synchronization protocol, a terminal device status synchronization protocol, and a synchronization detection protocol. To ensure the coordination of the entire gatekeeper group, and use the synchronization protocol to achieve the transmission of changes and effectively avoid the waste of network bandwidth caused by the entire data being transmitted.
- Each gatekeeper performs synchronous detection regularly.
- the method for each gatekeeper to perform synchronous detection at regular intervals is to generate a check code and compare it with the data of the authorized gatekeeper configured in the gatekeeper group.
- the currently registered gateway can be transferred to the gatekeeper group
- Other gatekeepers without faults continue to process the call without stopping the call, and after transferring the gateway, they can automatically synchronize data from the authoritative gatekeeper and restart the service after the synchronization is completed.
- the method for mapping from a single gatekeeper to multiple gatekeepers in the above step 3 is to represent the gatekeeper group with a unified domain name, so that the gateway feels only the existence of a gatekeeper, that is, to ensure that the gatekeeper group is transparent,
- This domain name is automatically translated into the network transmission addresses of multiple gatekeepers by the domain name resolution system, and the gatekeepers are automatically switched, so that each gateway can obtain the transmission address list of multiple gatekeepers through the domain name resolution system.
- the method for mapping from single gatekeeper to multiple gatekeepers in this step mainly includes the following processes: a. Before the gateway sends a GRQ (gatekeeper request) to make a gatekeeper application, it first obtains the gatekeeper group through the domain name resolution system. Member address list, and select a gatekeeper with the highest priority to issue a GRQ (gatekeeper request) according to the static priority set in DNS (Domain Name Server) in advance;
- the gatekeeper that receives the GRQ returns a list of registerable gatekeepers arranged by the load size to the gateway through the GCF (gatekeeper confirmation) message according to the load of the members of the gatekeeper group over a period of time;
- the gateway selects a gatekeeper with a lower load to issue an RRQ (Registration Request) registration application based on the load of the list of registerable gatekeepers received.
