Definitions

  • the present invention relates generally to telecommunications systems and methods for accessing and manipulating subscriber or network information stored in an Intelligent Network (IN) node, and specifically to providing a direct hypertext transfer protocol (http) interface to the IN node.
  • IN Intelligent Network
  • http hypertext transfer protocol
  • signaling constitutes the distinct control infrastructure that enables provision of all other services. It can be defined as the system that enables stored program control exchanges, network databases, and other "intelligent" nodes of the network to exchange: (a) messages related to call setup, supervision, and tear-down; (b) information needed for distributed applications processing (inter-process query/response); and (c) network management information.
  • ATN Access Network
  • Telephone service representatives can, therefore, create new services and tailor a subscriber's service from a terminal while talking with the customer. These changes are immediately and inexpensively implemented in the switches, rather than by the more traditional method: expensive programming changes made by certified technicians.
  • the IN consists of a series of intelligent nodes, each capable of processing at various levels, and each capable of communicating with one another over data links.
  • the basic infrastructure needed is composed of various signaling points, which both perform message discrimination (read the address and determine if the message is for that node), and route messages to other signaling points.
  • the basic three types of signaling points are: (1) Service Switching Points (SSPs); (2) Signal Transfer Points (STPs); and (3) Service Control Points (SCPs), each of which are described in more detail hereinafter.
  • the many Service Switching Points (SSPs) 100 serve as the local exchanges in a telephone network 90, a portion of which is shown in FIGURE 1.
  • the SSPs 100 also provide an Integrated Services Digital Network (ISDN) interface for the Signal Transfer Points (STPs) 110, as is understood in the art.
  • ISDN signaling uses a separate channel and is compatible with the IN. The signaling information is handed off to the IN network and transferred to the end office (another SSP) using an ISDN User Part (ISUP) protocol, which is responsible for all call setup and tear down.
  • ISUP ISDN User Part
  • the STP 110 serves as a router, and switches messages received from a particular SSP 100 through the network 90 to their appropriate destinations (another SSP 100). As is also understood in the art, the STP 110 receives messages in packet form from the SSPs 100. These packets are either related to call connections or database queries. If the packet is a request to connect a call, the message must be forwarded to a destination end office (another SSP 100), where the call will be terminated.
  • the destination will be a database. Database access is provided through the Service
  • Control Point (SCP) 120 which does not store the information, but acts as an interface to a computer that houses the requested information.
  • GUIs graphical user interfaces
  • GUIs are generally much easier to use, they require a great deal of time to program and maintain, they must be ported and recompiled for every platform they are to run on, and the user has to use a different program for each type of administration they wish to perform. In fact, due to the overhead in writing and deploying these GUIs, most administrative functions have only text interfaces. With reference now to FIGURE 2 of the drawings, an alternative way of remotely accessing the information contained in these IN nodes 240, which is not widely used today, utilizes a web server 220.
  • a user 200 can request access to a specific web page or file 245 associated with the IN node 240 by entering an address, e ⁇ , http://www.URL.com/file, from a web browser 205, e.g.. Netscape or Internet Explorer, within the computer 200, which can then determine which web server 220 to send the hypertext transfer protocol (http) request to based upon the entered Uniform Resource Locator (URL), which is an identification of the IN node 240 the user 200 wishes to access.
  • http Hypertext transfer protocol
  • URL Uniform Resource Locator
  • the web browser 205 can then send the request to that web server 220 through a data network 210, e ⁇ , the computer's 200 modem can dial a number for an Internet Service Provider (ISP) (not shown), and an SSP 100 or end office serving the user 200 can route the call to the ISP, which can then route the request through various network devices (not shown), such as hubs, routers and bridges, as is understood in the art.
  • ISP Internet Service Provider
  • SSP 100 or end office serving the user 200 can route the call to the ISP, which can then route the request through various network devices (not shown), such as hubs, routers and bridges, as is understood in the art.
  • the web browser 205 can send the request directly to the web server 220 through the various network devices.
  • the web server 220 can then establish a connection with the IN node 240 associated with the address using an intermediating Common Gateway Interface (CGI script) 230.
  • the IN node 240 can then retrieve the requested file (web page) 245 and send the file 245 back to the user 200 through the web server 220 and the data network 210 for display on a computer screen 202.
  • the user 200 can then manipulate the data within the web page 245, which is displayed on the screen 202, from the web browser 205 on the remote computer 200.
  • general-purpose web servers 220 are complex and difficult to administer, and typically require a full- time employee to ensure proper operation.
  • utilizing web servers 220 to access information from IN nodes 240 requires an increase in interprocess communications, which provides for inefficient use of network resources.
  • the code required to create and maintain the interface between the web server 220 and the IN node e.g.. the CGI script, is cumbersome to administer and update. It is, therefore, an object of the present invention to provide a direct hypertext transfer protocol (http) interface to an IN node in order to allow remote administration ofthe lN node.
  • the present invention is directed to telecommunications systems and methods for providing a direct hypertext transfer protocol (http) interface into an IN node containing subscriber and/or network information.
  • the http interface provides a method of remotely administering an IN node that combines the platform independence and manageability of a text interface with the shallow learning curve and useability of a graphical interface.
  • any computer, workstation, or other web-capable machine connected to the same data network as the IN node can start a web browser, e ⁇ , Netscape, Internet Explorer, etc., type in a Uniform Resource Locator (URL), which is an identification of the IN node the user wishes to access, and access the IN node in order to enter administrative functions from the web browser.

  • a hypertext transfer protocol (http) interface 330 can be implemented directly into an Intelligent Network (IN) node 320 to provide a method of remotely administering the IN node 320 that combines the platform independence and manageability of a text interface with the shallow learning curve and useability of a graphical interface.
  • the IN node 320 can contain, for example, network and/or subscriber information.
  • any personal computer (PC) 300, workstation, or other web-capable machine connected to the same data network as the IN node 320 can start a "web browser" 310, £ ⁇ , Netscape or Internet Explorer, within the computer 300, and type in a Uniform
  • URL 308 which is an identification of the information the user wishes to access, in order to enter administrative functions for the IN node 320 directly from the web browser 310.
  • the IN node 320 must first open a listener port 325, e.g., a Transmission Control Protocol/Internet Protocol (TCP/IP) listener port 325, to which the web browser 310 can connect.
  • TCP/IP Transmission Control Protocol/Internet Protocol
  • the TCP/IP was developed as a standard protocol to allow different types of computers to exchange electronic mail and other files over a network.
  • the TCP/IP specifies the addressing of nodes on the Internet and provides a method of sending packets of data from one node to another.
  • the TCP is an application implemented on top of the IP to provide reliable delivery of the data packets end-to-end. It should be understood that other protocols can be used instead of TCP/IP, such as the User Datagram Protocol (UDP), which is faster than the TCP, but less reliable.
  • UDP User Datagram Protocol
  • the "web browser” 310 sends an http request 305 to the IN node 320. Thereafter, the IN node 320 parses the request 305, performs any relevant actions based upon the user's request 305, and sends back the requested data or a confirmation that the requested action has been performed.
  • the user in order to access the IN node 320 (step 450), the user must first start-up the "web browser" 310 on the user's computer 300 (step 400) and type in the URL 308 (step 410) formed by the IN node 320 name and the predetermined TCP port 325 number the IN node 320 listens to. If, for example, the IN node 320 is called “fonzie" and the port 325 number is 9022, the URL 308 can be "http://fonzie:9022/.” The user's "web browser” 310 then attempts to contact fonzie 320 on TCP port 325 number 9022 (step 420). When the "web browser" 310 connects to port 325 number 9022 on fonzie 320
  • the web browser 310 can then send an http request 305 (step 430), as is understood in the art.
  • the http interface 330 within the IN node 320 then decodes the http request 305 (step 440) by determining the type of request 305, such as a "GET" request 305, which instructs the IN node 320 to retrieve information, and the exact type of data being requested.
  • the type of data being requested can be specified by any information after the final slash in the URL 308, e ⁇ , if the user wishes to access system status information, the URL 308 can be "http://fonzie:9022/status".
  • access to certain information can be password protected, and this password can be included in the URL 308 or prompted by the http interface 330 when the URL 308 is received.
  • the actual URL 308, including the type of information required can be kept transparent to the user by displaying a menu on a display or screen 302 of the computer 300 if no indication of the desired information is included.
  • the request 305 can include attributes which modify the request 305. For example, if the user desires information concerning calls placed to the phone number "555-1234" for the past five days, the format of the URL 308 can be:
  • the http interface 330 within the IN node 320 can then generate a markup language page 340, such as a Hypertext Markup Language (HTML) page 340 (step 450), which is sent to the computer 300 from the http interface 330 via the web browser 310 (step 460).
  • HTML page 340 contains the information that the user requested and presents this information to the user via the web browser 310 on the computer screen 302.
  • the HTML page 340 can contain further links to request different information from the IN node 320 and links which point to other information contained on other
  • the web browser 310 can be resident within the IN node 320 itself. Thus, instead of remotely accessing the IN node 320, the administration of the IN node 320 can be performed at the IN node 320 through the use of the web browser 310.
