Abstract

System, method and program product for managing a chat session. A server maintains an identity and list of member(s) of a group that can be added to a chat session, and a list of people authorized to request that the group of member(s) be added to the chat session. A person in a chat session at a workstation makes a request to add the group of member(s) to the chat session. In response, the workstation sends the request to the server. In response to the request, the server determines if the person is authorized to add the group to the chat session. If so, the server sends an invitation to the member(s) to join the chat session. If not, the server does not send an invitation to the member(s) to join the chat session. To make the request to add the group to the chat session, the person can enter in a chat session text field a character string that is a command to add the group to the chat session. A program at the workstation monitors the text field and determines that the character string is the command to add the group to the chat session.

Claims

1. A method for managing a chat session, the method comprising the steps of:

a server storing in a database an identity of a group, a list of a plurality of members of the group, and a list of people authorized to request that the group of members be added to the chat session;

the server receiving a request from a workstation of a person participating in the chat session to add the group of members to the chat session, the request initiated by the person participating in the chat session at the workstation, the request specifying the identity of the group but not the members of the group;

in response to the request initiated by the person participating in the chat session at the workstation, the server determining if the person which initiated the request is authorized to add the group of members to the chat session, and if so, the server determining from the database identities of members of the group and sending an invitation to the members of the group to join the chat session, and if not, the server not sending an invitation to the members of the group to join the chat session in response to the request initiated by the person participating in the chat session at the workstation;

the workstation receiving from the person which initiated the request entry in a chat session message text field of a character string to add the group of members to the chat session; and

a program stored in a computer readable storage device and executing at the workstation monitoring the chat session message text field and determining that the character string is the request to add the group of members to the chat session, and in response, the program forming and initiating sending of the request to the server to add the group of members to the chat session; and

wherein the character string comprises an identity of the group of members surrounded by symbols which differentiate the character string from chat message text in the chat message text field.

2. The method of claim 1 wherein in response to the request to add the members of the group to the chat session further comprising the steps of:

the server obtaining from the members of the group a credential and determining if the credential is valid, and if so, joining the members of the group to the chat session.

3. The method of claim 1 wherein if the person which initiated the request to add the members of the group to the chat session is authorized to add the members of the group to the chat session, and the server sends an invitation to the members of the group to join the chat session, further comprising the steps of:

the members of the group responding to the server with acceptances to join the chat session; and

the server joining the members of the group to the chat session.

4. The method of claim 1 wherein none of the members of the group is participating in the chat session when the person which initiated the request to add the group of members to the chat session made the request to add the group of members to the chat session.

5. The method of claim 1 further comprising the prior step of another workstation establishing the group at the server by specifying to the server via a network the identity of the group and the list of the plurality of members of the group.

6. A method for managing a chat session, the method comprising the steps of:

a server receiving a request from a workstation of a person participating in the chat session to add a group of members to the chat session, the request initiated by the person participating in the chat session at the workstation, the request specifying an identity of the group but not the members of the group;

in response to the request initiated by the person participating in the chat session at the workstation, the server determining if the person which initiated the request is authorized to add the group of members to the chat session, and if so, the server determining from a database identities of members of the group and sending an invitation to the members of the group to join the chat session, and if not, the server not sending an invitation to the members of the group to join the chat session in response to the request initiated by the person participating in the chat session at the workstation;

the server receiving another request from another workstation of another person participating in another chat session to add the group of members to the other chat session, the request initiated by the other person participating in the other chat session at the other workstation, the other request specifying the identity of the group but not the members of the group; and

in response to the other request initiated by the other person participating in the other chat session at other workstation, the server determining if the other person which initiated the other request is authorized to add the group of members to the other chat session, and if so, the server determining from the database identities of members of the group and sending an invitation to the members of the group to join the other chat session, and if not, the server not sending an invitation to the members of the group to join the other chat session in response to the other request initiated by the other person participating in the other chat session at the other workstation.

7. The method of claim 6 wherein the database is accessible by the server, and the database includes the identity of the group, a list of the members of the group, and a list of people authorized to request that the group of members be added to a chat session.
