Apparatus and method for multiplexing special resource of intelligent network-intelligent peripheral
View Patent ↗An apparatus and method for multiplexing a special resource of an intelligent network-intelligent peripheral (IN-IP) are disclosed, including a plurality of specialized resources that provide services to subscriber calls, contacting an intelligent network, and a plurality of modules that manage groups of the specialized resources. A main processor manages the plurality of modules and collects state information from each of the modules. A resource management block restores a service to a subscriber call, disrupted by a faulty one of the specialized resources, in accordance with the state information collected by the main processor.
1. An apparatus for multiplexing a specialized resource of a network peripheral, comprising:
a plurality of specialized resources that provide services to subscriber calls contacting a network;
a plurality of modules that manage a number of specialized resource groups;
a main processor that manages the plurality of modules and collects state information from each of the plurality of modules;
a resource management block that restores a service to a subscriber call, disrupted by a faulty one of the plurality of specialized resources, in accordance with the state information collected by the main processor;
a means for isolating the faulty one of the plurality of specialized resources; and
a means for generating a multiplexing message, according to the collected state information, and dispersively transmitting the multiplexing message to particular modules, of the plurality of modules, having a small load and a particular specialized resource available to replace the isolated specialized resource.
2. The apparatus of claim 1 , wherein the resource management block includes:
a means for collecting information about the service performed by the isolated specialized resource and information about the particular specialized resource available to replace the isolated specialized resource; and
a means for resuming the service disrupted by the faulty one of the plurality of specialized resources.
3. The apparatus of claim 1 , wherein the multiplexing message is generated for each subscriber call disrupted by a faulty one of the plurality of specialized resources.
4. The apparatus of claim 1 , wherein the multiplexing message includes information identifying a number of a particular module having the particular specialized resource available, an index of the particular specialized resource, and a type of the service disrupted by the faulty one of the plurality of specialized resources.
5. The apparatus of claim 1 , wherein the state information comprises specialized resource number information, indicating the number of specialized resources supported by the corresponding module, and a specialized resource state bit map indicating a state of each of the specialized resources supported by the corresponding module.
6. The apparatus of claim 1 , wherein the state information is collected from all of the plurality of modules of the network peripheral.
7. The apparatus of claim 1 , wherein the resource management block is a virtual device implemented by software.
8. A method of multiplexing a specialized resource of an intelligent network-intelligent peripheral (In-IP), comprising:
collecting state information of specialized resources from all modules of an IP;
checking whether an error occurred, in each of the specialized resources, by analyzing the collected state information;
isolating a pertinent specialized resource that experienced the error;
collecting information about a service performed by the isolated specialized resource and information about a particular specialized resource available to replace the isolated specialized resource;
generating a multiplexing message, according to the collected information, and dispersively transmitting the multiplexing message to selected ones of the modules having a small load and the particular specialized resource available; and
resuming the service interrupted by the error, in accordance with the multiplexing message.
9. The method of claim 8 , wherein the state information comprises number information, indicating the number of specialized resources supported by the corresponding module, and a state bit map indicating a state of each of the supported special resources.
10. The method of claim 8 , wherein the multiplexing message is generated for each service disrupted by a faulty one of the specialized resources.
11. The method of claim 8 , wherein the multiplexing message includes information identifying a number of the particular module having the particular specialized resource available, an index of the particular specialized resource, and the service.
12. The method of claim 8 , wherein the state information is periodically collected from all of the modules.
