BACKGROUND
Object and Network Discovery
As used herein the term “discovery” means the identification and characterization of all relevant information surrounding an event relating to a device being connected or disconnected on a network. The event may be the appearance or disappearance of connectivity of the device, such as a previously unregistered telephone, or any other device state change.
As used herein the term “device” means an NIU, NAU, or any form of logical or physical terminating device.
As used herein the term “Host Switch” means to designate service LDS for a customer.
As used herein the term “Hot-line” is also known as a “warm” or “ring down” line, which transfers a caller to a specific number immediately upon detection that the device connected to the line goes into an origination mode (i.e. off hook).
As used herein the term “Multi-hosting” means the association of one network element with more than one other network element. It is a form of addressing network growth in which service areas attributable to an element are overlapped.
As used herein the term “Soft-Disconnect” means the assignment of an SDT behavioral characteristic to a line. Normally the assignment to a line is permanent, but may be also termed “virtual” SDT when it is spontaneously assigned.
As used herein the term “Hard Disconnect” means that all assigned resources and physical devices are returned to inventory.
As used herein the term “Switch” means a Local Digital Switch or LDS, which accommodates provisioning of services. It may be a normal or “soft” switch providing LDS.
All forms of discovery serve to acquire knowledge and information from a managed device. Discovery has been implemented in several forms in the industry. Automatic discovery has been used in data networks implementing SNMP or CMIP and has been used for inventory and security management. It is a polled function where the network management system periodically asks, “who's there?” or “what's there?” and processes the responses. However, the current standards also allow for autonomous event reports that in the form of auto announcements. VoIP and HSD Modem vendors have implemented an autonomous registration request message (REQ-REG) that causes the network management system to note the presence of the MTA device, request data from the modem, register the device and initialize the device as appropriate. Cable modem vendors have implemented a form of discovery in which the control channels are periodically scanned to institute what is known as ‘ranging’ or ‘marshaling’ to register the NAU with the HDT controller.
Normally, if the discovered device is not expected or registered, then alarms are triggered and the device is disabled.
Advanced Intelligent Network
Advanced Intelligent Network (AIN) was developed by Bellcore to separate service control from switch logic. Its primary advantage is that it provides flexibility for offering new services but also independence of vendor services which are often implemented differently. AIN provides these services to line accounts after they are provisioned into the Local Digital Switch (LDS).
AIN defines a formal call model to which all switching systems must adhere. The call model is implemented in the LDS known as the AIN Service Switching Point (SSP), which utilizes point in calls (PICs), detection points (DPs), and triggers. The AIN architecture introduces the Intelligent Peripheral (IPe) and then utilizes the Service Control Point (SCP) to provide call guidance.
AIN SSP formal call model introduces call states to track call origination to call termination. These states include the null state (or the “on-hook” idle state) when the phone is idle. Other PICs include off-hook (or origination attempt), collecting information, analyzing information, routing, alerting, etc. In this new call model, trigger detection points (TDPs) were added between the PICs. SSPs check TDPs to see if there are any active triggers.
There are three types of triggers, i.e. subscribed or line-based triggers, group-based triggers, and office-based triggers. Subscribed triggers are specifically provisioned to the customer's line. Group-based triggers are assigned to groups such as all lines in a Centrex group. Office-based triggers are available to everyone who is connected to the telephone switching office or has access to the North American numbering plan.
Normal switching system call processing continues until an active trigger is detected. The SSP then sends the event message to the IPe or SCP and awaits instructions before continuing call processi
