Abstract

A node configured for use in a telecommunications network. The node is programmable via an end-user-accessible interface to provide a mnemonic dialing service. The mnemonic dialing service allows members of a group to communicate with each other.

Claims

1. A method for configuring a membership of a group of users of a telecommunications network comprising the steps of:

receiving from a network end-user data indicative of a time frame within which the group will be in existence and entering said data onto a storage device accessible to a node of the network;

receiving enrollment information from one or more network end users who desire to become members of the group; and

storing said enrollment information to facilitate the node in providing a mnemonic dialing service among members of the group.

2. The method of configuring a node as claimed in claim 1 wherein said enrollment information is received at an enrollment unit coupled to said node, the enrollment unit being configured to automatically detect an identification number of a telephone, and to issue programming signals to the node to enroll the telephone into the mnemonic dialing group.

3. A method for automatic conference calling comprising the steps of:

storing a configuration of a group of users of a telecommunications network in a memory of a node internal to the network, the node'"'"'s stored group configuration of the group of users being accessible to members of the group of users and persisting beyond a single telephone call connected among the members of the group of users;

at the node, receiving a signal from an end-user device of an initiating member of the group of users;

without human supervision, sending from said node a supervisory signal to appropriate end-user devices of the remaining members of the group of users, and establishing a communication path to two or more of said devices of said remaining members of the group of users when said devices respond to said supervisory signals.

4. A method for establishing a conference call, comprising the steps of:

on detecting initiation of a telephone call, referencing a database to determine whether the initiating telephone line is a member of a closed-user group, the closed user group including at least three telephone lines of a telecommunications system; and

automatically, and without further human intervention, establishing a conference call among the initiating telephone line and one or more members of the closed-user group by issuing supervisory signals directed to other member lines of the closed-user group as selected by the reference to the database and establishing a communication path interconnecting member devices of the closed-user group that respond to said supervisory signals.

5. A method of operating a communications network, comprising:

detecting a signal from a wireless telephone set, the detected signal including an identification number of the wireless telephone set;

determining a pre-defined group network into which the identification number is to be enrolled as a member;

transmitting the identification number to the communications network to enroll the identification number into said predefined group network, said group network being a group of telephone sets having reciprocal mnemonic dialing access to each other.

6. A telecommunication network, comprising:

a node configured for use in said telecommunications network, the node being programmable to provide a mnemonic dialing service among members of a group; and

an enrollment unit configured to automatically detect an identification number of a telephone, and to issue programming signals to the node to enroll the telephone into the mnemonic dialing group.

7. The telecommunication network of claim 6, the enrollment unit further comprising a clock, and being configured to consult said clock to determine one out of a plurality of such mnemonic dialing groups into which to enroll the detected telephone unit.

8. The telecommunication network of claim 6, the enrollment unit being configured to establish a connection between the enrollment unit, a local cellular switch, and a database node to collect and process information to enroll the telephone into the mnemonic dialing group.

9. A method for connecting a telephone call, comprising:

consulting a group membership database to determine group membership of an initiator of the call, the group membership as stored in the group membership database having been configured by a member subscriber of the group via a subscriber-accessible interface, the group membership database being available to members of the group to identify the group'"'"'s member lines; and

connecting the call between the line at which the call is initiated and one or more member lines of the group.
