The technical FIELD

The invention relates in General to technology, IP networks, in particular to a method of treatment from one zone to another within the system of IP networks. It is a technology that allows you to assign a unique IP aliases for all endpoints H.323 IP network.

The LEVEL of TECHNOLOGY

The H.323 Protocol was used mainly in multimedia systems conference and at present it is widely used in IP telephony. The system of the H.323 standard offers multimedia data in a network packet. The network packet includes a local network, the enterprise network and the network of the city and the suburbs, etc. that do not provide a guaranteed quality of service. System standard H.323 consists of terminals, gateways, devices, management conferences (MCU), zone controllers (GK), etc. Endpoint H.323 includes a terminal, gateway or device management conference (MCU). Endpoint H.323 registered in his own zone controller and served in this zone controller.

In systems of the H.323 standard is one of the main services provided by the zone controller is address resolution, including the conversion of the alias of the endpoint in the IP address of the endpoint. The alias of the endpoint includes the phone number 164, H.323 ID, URL and E-mail address of the other, these aliases are registered at the zone controller through the alarm Registration Request (RRQ) Protocol N logging and Status (RAS) from the endpoint. In the system of the H.323 standard can be a lot of zone controllers. Each zone controller contains one or more zone controllers and the set of endpoints, each endpoint is registered accordingly with your own controller.

This standard Protocol each alias of the endpoint in the zone controller must be unique, but the aliases endpoints in different zones of the controllers do not have this restriction. Thus, it is possible that different endpoints in different zones of the controllers can have the same alias. This causes difficulties when calling and addressing endpoints from one zone to another.

1 shows a network system with the H.323 Protocol with two zones of controllers: Area 1, controlled by the controller GK1, and Zone 2 is controlled by the controller GK2, and in these areas there are duplicate aliases endpoints. In Zone 1 there are three endpoint aliases 123456, 123123 and 123789 respectively. In Zone 2 there are three endpoints with the same aliases: 123456, 123123 and 123789 respectively. In this case, the IP addresses of the end points in one area can be obtained through the service allowed the program address of the controller, where is the endpoint, but the endpoint in various areas there is no possibility of converting IP addresses of the endpoints with the same alias.

For example, suppose that the endpoint 123456 Zone 1 makes a call to the endpoint 123123 Zone 2, the controller GK1 can convert the called endpoint in the IP address in Zone 1 and return the IP address to the calling point 123456, but cannot convert IP address alias 123123 called point in Zone 2 and return to the alias 123456 calling endpoint.

The advantage of the method described above configurations for aliases endpoints is that there are no restrictions for each alias name of the endpoint in each zone controller. However, as in the systems of the H.323 standard no identical configuration method for aliases, the controller may convert the IP addresses of the end points only in their own area, but not in the other zones. This is the reason for the lack of technology that guarantees uniqueness of each alias endpoints throughout the network.

Currently in the development process of the transmission of video over IP networks and increase the number of endpoints in IP networks is becoming more and more necessary assign a unique IP alias for the endpoint.

A BRIEF description of the IMAGE IS the SHADOW

The aim of the invention is to develop a way of reaching the end point from one zone to another within the system IP network. When assigning endpoints of the same all aliases aliases endpoints in the network is unique, thus, handling and addressing from one zone to another between any two endpoints in different zones of the controllers can be easily performed in the IP network.

The technical scheme of the invention is the following: how to access an endpoint from one zone to another within the system IP network differs in that it includes the following operations:

A. Pre-registration alias 164 each endpoint of each controller your controller in the system IP network, where the alias 164 includes a unique prefix zone in the system IP network and a unique number specified endpoint from your controller;

C. Performing a direct appeal from the calling endpoint to the called endpoint alias 164 of the called endpoint.

The specified operation is In addition includes the following operations:

A. The controller of the calling endpoint, receiving the admission request (ARQ), sends the signal from the specified endpoint;

b. The controller of the calling endpoint retrieves the prefix alias 164 of the called endpoint and looks up the IP address of the controller end-point and, corresponding to the prefix, and then in accordance with the IP address sends a call LRQ (query location) to the controller of the called endpoint with the request to convert the IP address of the called endpoint;

C. the Controller of the called endpoint translates the IP address of the called endpoint in accordance with the alias 164 of the called endpoint and sends the response back to the controller, the calling endpoint in the form of a signal LCF (confirm location);

d. The controller of the calling endpoint informs the calling endpoint on the IP address of the called endpoint with alarm ACF (Admission Confirm - Confirmation of Admission);

f. The calling endpoint sends the alarm setting treatment Q.931 to the called endpoint in accordance with the IP address of the called endpoint and initiates the conversion.

The invention requires that each zone controller in the IP network was assigned a unique number for the formation of a prefix alias endpoint and generates a number of the endpoint alias endpoint using a unique number to each endpoint within each zone controller; and then is "the specified prefix for the zone controller + number end point" for the formation of a pre-defined (pre-registered) p is avgonima 164 endpoint.

Compared with the known solutions, the invention solves the problem of uniqueness alias endpoints throughout the network. Thus, any controller in the network can convert the IP address of an endpoint in the IP network in accordance with aliases. Thus, it is possible to conveniently perform the conversion from one zone to another zone.

BRIEF DESCRIPTION of DRAWINGS

Figure 1 depicts a General diagram of the system of H.323 end points and zones in accordance with the known solutions.

Figure 2 depicts a system diagram of H.323 end points and zones according to one variant embodiment of the invention.

Figure 3 depicts the application process from one zone to another.

VARIANTS of the EMBODIMENT of the INVENTION

The invention is described below in more detail with reference to the drawings.

The basic idea is to assign each endpoint of a unique alias is as follows: first, each endpoint in each zone is assigned a number format 164 as a unique alias in your zone, i.e. a predefined number 164 each endpoint register of the controller, which controls this endpoint; then the number 164 combined with a unique zone number of each zone controller in the system network for education unique alias of the endpoint. With this unique what about the alias are addressing and conversion from one zone to another.

Figure 2 shows three zone controllers, and each zone has a unique number as the prefix for the formation of an endpoint name. Each prefix area of the controller is not repeated throughout the system IP network. For example, the prefix area of the controller 1 - 0755, the prefix area of the controller 2 is 010, and the prefix area of the controller 3 - 021.

In one zone controller 164 rooms all endpoints in this area are not repeated, but in different zones of rooms 164 endpoints may be the same, for example in all three zones 1, 2 and 3 are the same part number 123456, 123123 and 123789.

According to the invention, each alias of the endpoint in each zone controller is composed of "Prefix zone controller" + "Number 164 endpoints. For example, in Zone 1, there are three alias endpoint: 0755123456, 0755123123 and 0755123789, three alias endpoints in Zone 2: 010123456, 101123123 and 010123789 and three alias endpoints in Zone 3: 021123456, 0211123123 and 021123789. With this method of naming each alias of the endpoint of the whole network is unique.

As each alias endpoint is pre-determined by the controller, the registration must be made in accordance with the assigned aliases. This ensures the uniqueness of aliases endpoints.

The invention solved the problem of the uniqueness of aliases endpoints, thus, offered the technical basis for the implementation of trips from one zone to another.

Suppose that, as shown in figure 3 and 2, End point And alias 0755123456 forwards the call to the Endpoint In the alias 010123123, the procedure will be as follows:

Operation 1, the End point a (0755123456) sends an ARQ call (request for admission to the controller 1;

Operation 2, the controller 1 reads the prefix 010 alias of the called endpoint from the received call, and determines based on the prefix that the called Endpoint is located in a zone controller 2 (i.e., the controller 1 obtains the IP address of the called controller 2); and then the controller 1 sends a call LRQ (query location) with the alias 010123123 the called endpoint to the controller 2 with the request for conversion of the IP address of the Endpoint;

Step 3, after receiving the call LRQ controller 2 converts the IP address of Endpoint 2 in accordance with the alias 010123123 the called endpoint sends a response signal LCF (confirm location) with the IP address of the Endpoint In the controller 1;

Step 4, after receiving the response signal LCF controller 1 responds with a signal ACF (Admission Confirm - Confirmation of Admission) with the IP address of the Endpoint b to Endpoint A;

Operation 5, in accordance with the IP address of the Endpoint, the Endpoint And sends the alarm setting treatment Q.931 to the End point In installed for the I treatment;

Operation 6, the procedure enters into the mode of a call.

The invention uses the same naming Convention for all aliases endpoints in the system IP network using aliases format 164. Thus, addressing and accessing the endpoint from one zone to another easier and easier. The tests showed that the method will perform and reliable.

1. How to access the endpoint from one zone to another within the system IP network, comprising the steps:

a) pre-registration alias 164 each endpoint of each controller your controller in the system IP network, where the E.164 alias includes a unique prefix zone in the system IP network and a unique number specified endpoint from your controller;

C) the controller receives a calling end point of the specified query from the calling endpoint;

g) removing the prefix alias 164 of the called endpoint and search for the IP address of the controller of the called endpoint, corresponding to the prefix, and then in accordance with the IP address for the controller of the called endpoint request preobrazovanie IP address of the called endpoint;

d) change the s controller of the called endpoint IP address of the called endpoint in accordance with the E.164 alias of the called endpoint and direction of the response to the controller, the calling endpoint;

e) informing the calling endpoint controller of the calling endpoint on the IP address of the called endpoint;

g) the direction of the calling end point alarm setting appeals to the called endpoint in accordance with the IP address of the called endpoint and the initiation of treatment.
