Description

TECHNICAL FIELD The present invention relates to access technologies in the field of communications, and more particularly to an access network configuration method and apparatus for a next-generation network NGN. BACKGROUND OF THE INVENTION A telecommunications network is undergoing a transition from a traditional PSTN to an NGN network. The construction mode of the switching office and the access network is gradually being used by the service network, SS (Soft Switch, Soft Switch), AG (Note: TG, SG). Replaced by the flat network, the current AG equipment used for network construction includes the following types: 1. TG/SG equipment connected to the PSTN network boundary; 2. deployed in the original module office, used to replace the C5 station status AG equipment; Third, small and medium-sized access point equipment widely distributed with users; and four, micro AG, plug-in AG or desktop box AG equipment attached to DSLAM. In addition, various media gateway devices are divided into three categories according to the specific aspects of the device: 1. Large-scale trunking gateway equipment, used for the edge of the NGN network and the traditional PSTN network, such devices have strong letters. It is characterized by processing power (SG) and a large number of VOIP capabilities (TG). Such devices do not directly represent users. In general, TG has strong media capabilities and also provides some complementary media for AGs. For example, the conference capability is generally provided by the TG. 2. Second, various large and small-capacity user access devices, the capacity of a single device is as large as 100,000 or more or as small as 128 lines, and users of such devices have access. Capability and VOIP conversion capability and uplink service interface control capability. For large and medium-sized devices, there are primary and secondary nodes, main control frames, and user frames. On the capacity requirement ladder, multiple devices are superimposed to achieve a single device that cannot be satisfied. Capacity requirements; and 3. AG board and desktop (box) AG equipment for single board voice access of DSLAM equipment, where terminal type IAD Belong to this category, but not the focus of this discussion, which

1 P 16777 Class devices are suitable for sporadic access points with few users in the application. The number of users/service interfaces is small, and it is difficult to promote them in large areas in areas where there are a large number of DSLAMs deployed. These access gateway devices are referred to as "homogeneous access network elements" in this description. Their common feature is that they have a service interface (generally H.248 interface) and have the ability to access users (usually said The AG accesses the ordinary user, and the TG/SG accesses the relay user of the PSTN network) and provides the capability of media conversion, which is controlled by the control unit (commonly referred to as the main control board) and the user board and the media resource board or the daughter card. The three together form the access gateway device. The binding relationship of the three is determined by the device manufacturer design and cannot be adjusted during the production and deployment of the device. However, the complexity of the access layer network leads to the diversity of user access devices. It can be said that in any actual network, various devices exist at the same time, leaving TG/SG and user access alone. In terms of equipment, it not only covers large, medium and small equipment, but also has the application requirements of single-board and desktop micro-AG equipment. This makes the construction of the entire user access network more difficult, if you consider future development. The benign evolution of the network is more susceptible to the jaggedness of the device; for the service interface planning of the softswitch (SS) device, the planning of the control interface (usually H.248) seems to have no rules. It is completely closely related to the geographical location of the user access (and the selection of the device). The setting of the service has to consider the situation of the underlying access device. For example, for each additional 100 user AG node, a small device needs to add an H. .248 service interface, if there is a local DSLAM, and you want to use the plug-in AG of the DSLAM to access, you need 3-4 H.248 interfaces, but with large AG coverage is not To increase the H.248 interfaces, users only need to add large equipment already on an interface. Such business planning cannot achieve the original level of the business and regional planning, and it is difficult to reflect the clear structure that NGN presents to the telecommunications network. From the perspective of access network operation and maintenance, the access network has fewer types of devices, but there are many models and a large number. The same AG devices can be said to be different in terms of capacity, board type, and frame type. Different devices have different devices. Different maintenance interfaces (OAM station interface, physical interface) rely on views with different shapes on the service maintenance and device fault maintenance of the device. They cannot be classified and presented in a unified maintenance interface. From the perspective of equipment manufacturing, each AG has a certain configuration capability, which is the maximum configuration capability of the device, such as the maximum number of users and the largest number of VOIP resources. Each device passes the service control. The interface (such as H.248) is connected to the SoftSwitch/MGC. There is no connection between the access devices. FIG. 1 is a schematic diagram of networking of red SS and AG in the prior art. As shown in Figure 1, each AG

2 P16777 The SS network is the center of the star network. Each AG is independent and has no connection. The SS is connected to a variety of hardware devices with small to large capacity. It can be seen that when the AG device is configured, the shelf, the frame, and the board are configured in a step-by-step manner. The functions of the boards are different. Together, they form the function of the AG. In the configuration process, the functions in the network are not particularly The organization of the module provides the ability to change. The configuration is the hardware assignment. The system configuration is mostly based on the hardware design. It is a description of the hardware of the device. From the perspective of the entire network, there is no configuration capability, but only multiple devices. combination.

The component management identifier is at least the IP address of the component. The resource management relationship table includes at least: a component management identifier of the access component and the media resource component, and a connection of the access component and the media resource component

6 P 16777 The number of channels on the connection and the connection relationship between the access component and the media resource component, and the connection relationship between the access component and the media resource component may be one-to-one or one-to-one. In addition, the user creation module 306 can also include a new component configuration unit for determining the type of the new component when adding a new component, and configuring the component management identifier for the new component, and configuring the new component to be connected with the current component. The connection relationship of each component in the network, and the connection relationship is added to the resource management relationship table, wherein when the new component is the access component, the new component configuration unit is also used to create a new component user, and according to the resource management relationship The table enables the user to obtain the service provided by the media resource component in the access network through the new component, and when the new component is the media resource component, the new component configuration unit is also used to create the user of the new component, and according to the resource management relationship table, Enables new components to provide monthly service to users accessing access components within the network. Therefore, it should be understood that the AG equipment is generally configured as follows:

(1) Create a service interface (such as creating an H.248 interface) and related parameters;

(2) Insert the user card in a certain slot and configure the user card.

(3) Insert a media resource board and configure a resource board in some slots;

(4) Creating a user, the user can enter the business month. In this process, an AG device has a management identifier, which can be an internal AG# or a management IP address identifier. The slot of the user board and the slot of the media resource board are determined by the device design. Can be mixed or independently occupied. In addition, the number of user boards and media resource boards is also determined by the device design. Some AG devices are in the form of OLT/ONU, but the method is the same, except that the number of frames of the user boards is large; There is also a management ID. There is no process for configuring a board in the configuration. There is also a process for creating a service interface and a service user. 4 is a schematic diagram of a system involved in the present invention. As shown in FIG. 4, the board in the access gateway is divided into two components, namely, an access component 402 and a media resource component 404. The two components respectively have respective management identifiers, and the management identifier is usually an IP address. Each of them interacts with the main control device for control information. The management identifier of the two components varies with the number of components, and may be multiple or shared. In the figure, the main control device is the main body of the AG, which is called the main control frame and has the optical line end in the access network.

P 16777 The status of the OLT, which has a service interface, can be used to connect to the service control device such as the SS, and is responsible for the signaling processing, configuration management, and device monitoring tasks of the entire access gateway. The main control frame provides an Ethernet interface externally. To connect the various access components and media resource components, they can be connected by Ethernet light or cable, or can be connected through an Ethernet switch. When configuring the device, in addition to configuring the management identifier (such as the IP address) of each component, you also need to specify the mutual relationship between the access component and the media resource component. This relationship depends on the hardware connection. Used to indicate which media resources are served by the accessed service. In the software of the main control box, there is a data table for managing the use of resources, and the key value is corresponding to the time slot of the TDM exit in the access component, and the key value is corresponding to the media channel in the media resource component. Above, these three tables are shown in Table 1, Table 2, and Table 3. Table 1: Resource Management Table:

Table 2: Internal resource table for access components

Table 3: Internal Resource Tables for Media Resource Parts

Of the three tables, only Table 1 needs to be configured through the human-machine interface, while Tables 2 and 3 do not require human-machine interface configuration. They are generated when the software of each component is started (and Tables 2 and 3 will vary depending on the hardware design. The present invention only needs to clarify the role of Table 1, and Tables 2 and 3 belong to other implementation levels. The configuration of Table 1 can be performed separately or integrated in the creation of media resource components.

8 P 16777 In the process, but can be viewed and modified through the human-machine interface; in the business process (call process), the release of the resource is completely determined by the main control software, and the software of the access component and the media resource component is completely executed according to the instruction. It should be noted that the device can provide the capability of accommodating a heterogeneous network element node, such as a single board, a box, and the like. After the reconfigured AG device configuration process, after the hardware board of the device is installed and configured, the component configuration process must be performed. The newly added component configuration process is as follows: 1. Establish an access node and add components. The specific operation is to create a certain The access node may be a name, and then the identifier of the component (ie, the IP address of the component) is added thereto. 2. The connection relationship of the configuration component may be a connection relationship between the access component and the media resource component. It may be a connection relationship between the access component and the media resource component. The relationship is established between the two component identifiers. The human-machine interface needs to indicate the number of channels on the connection. In this man-machine operation, the system will establish a table. 1 internal entry, and all entries are idle; and 3. Create a user, the user can enter the service through the service interface. With such a configuration method, the same configuration of the access device in various forms can be realized, so that all the AGs in the network are presented in the form of components, and these components constitute an access network, and even some nodes are only one type. Component composition, the practical significance of this is on the one hand, when the network is built under the current situation, it can provide greater flexibility (more practical requirements) for the equipment selection of access points of various sizes and sizes. A more unified view of business planning and equipment management; on the other hand, a standard way of connecting internal devices is also proposed, and any component that conforms to this design, even a future design, can be accommodated in the running AG. The device, which will provide more room for the scalability of the device. Next, an example will be given. After the small-scale AG device completes the hardware installation and configuration of various boards, add the access component under the name of the device. The component identifier is the IP address of the user control board. Then, the media resource component is added, and the identifier is the media resource board. The management IP address, the media resource component is generally multi-block, and needs to be added one by one. Then, the affiliation relationship is configured, and the relationship between each media resource component and the access component is created according to Table 1. After the configuration is completed, the service user can be configured to enter the service service. . For a large-capacity AG device in the form of an optical access device, it has a central office OLT device and an ONU device of a user access point, and is connected by E1 (via SDH transmission), and there are multiple media in the central office equipment. Resource board, in the description of the present invention, TDM crossover between OLT-ONU

9 P16777 The control part belongs to the access component, and each of the media resource boards belongs to one media resource component. In the design disclosed by the present invention, after the hardware installation and configuration of the single board is completed, the two major components need to be configured separately according to the steps. ^ I with the same. We can imagine that if an access point is added under the AG (and the configuration of the service control interface may not be changed), if a single-board AG is added, then an access node is created and the access component is configured. And the media resource component (for the board AG, the two are the same), after the single-board AG is connected to the Ethernet of the OLT, the service can be provided by the large-capacity AG. Therefore, by establishing an intermediate level: the configuration of the two components, the various combinations of the AG network can be unified into one method, and the system designed according to this can accommodate different quality hardware devices in the initial deployment and medium-term operation. The networking hardware of the access network is thus greatly increased, and it is more adaptable to different geographical-user distributions. FIG. 5 is a schematic diagram of networking of SS and AG obtained by the present invention. As shown in Figure 5, the difference from Figure 2 is: First, the AG control component provides the ability to isolate the SS business plan; secondly, at the network level, it shows a clearer network hierarchy. It should be understood that the AG control component is only a software component that can run on a variety of hardware platforms and provides different control capabilities. In addition, it should be understood that the present invention makes the device shape in the network not completely dependent on the design of the manufacturer, but a combination of components that can be redefined, and the method is used to enable the operator to implement the configurable network while operating the service. possibility. The present invention divides the AG device into an access component and a media resource component. The two components can be in various relationships with the hardware board (form). For example, the access component has multiple boards, and the media resource component is composed of Multiple single boards are formed; or the access component and the media component are the same single board. In this way, in an AG device, various forms of access and media components can be accommodated, one AG device, covering All combinations of large and small frame devices listed above, and single board devices. In summary, the present invention provides an operator's ability to reconfigure the network on the human-machine interface, allowing the operator to adjust the network composition during the network evolution process, and the network device can provide changes as the operational requirements change. Ability, not subject to the design of the equipment manufacturer. The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.

10 P 16777 The present invention is susceptible to various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
