Offline IM chat to avoid server connections
An instant message (IM) connection is established at an IM server in the usual manner, under the policies and security rules promulgated by the IM service provider. Using this connection to the IM server, an offline IM chat request is made at the IM server for establishing an offline connection directly between consenting IM clients. The request may be included in a message to the IM server from a client, or the request may be in the form of IM session parameter, for the client, that authorizes an offline chat as the preferred type of IM session under certain conditions, such as the IM server being unavailable, IM server loading level or other factors that are under the control of the server. The conditions may also specify the presence of other IM clients as a criterion for establishing an offline chat, whether present in an online chat session or merely available.
1. A method within and performed by an instant message server, comprising:
receiving a connection request from a first computer client;
creating, in response to the connection request, a connection between the first computer client and a second computer client;
receiving a request for an offline session between the first computer client and the second computer client; and
forwarding a token to each of both the first computer client and the second computer client, wherein the first computer client creates the offline session by directly connecting, using the token and bypassing the instant message server, to the second computer, wherein
the first and second computer clients are both compliant with the instant message server.
2. The method of claim 1 , wherein
the forwarding the tokens is conditional upon a detection of a predefined performance metric associated with the instant message server.
3. The method of claim 1 , further comprising
forwarding, separately from the token, an authorization to the first computer client and the second computer client to create an offline session.
4. The method of claim 1 , further comprising
receiving a consent, from the first computer client, to automatically initiate the offline session based upon at least one factor.
5. The method of claim 4 , wherein
the at least one factor is selected from the group consisting of: identity of the second computer client, a security level of the second computer client, and a predefined performance metric associated with the instant message server.
6. The method of claim 4 , wherein
the consent is an advanced consent.
7. The method of claim 1 , wherein
prior to the token being forwarded, consent for the offline session is received from both the first computer client and the second computer client.
8. The method of claim 1 , wherein
the token for the second computer client is sent to the second computer client in a different transaction than the token for the first computer client is sent to the first computer client based upon an online status of the second computer client.
9. A method within and performed by a first computer client, comprising:
submitting a connection request to an instant message server;
connecting, via the instant message server, to a second computer client;
submitting a request to the instant message server for an offline session with the second computer client;
receiving a token from the instant message server; and
creating an offline session by directly connecting, using the token and bypassing the instant message server, to the second computer client,
wherein the first and second computer clients are both compliant with the instant message server.
10. The method of claim 9 , wherein
a creation of the offline session is conditional upon a detection of an outage within the instant message server.
11. The method of claim 9 , wherein
a creation of the offline session is conditional upon a predefined performance metric associated with the instant message server.
12. The method of claim 9 , wherein
a creation of the offline session is conditional upon security levels, respectively, of the first computer client and the second computer client.
13. The method of claim 9 , wherein
a creation of the offline session is conditional upon an identity of the second computer client.
14. The method of claim 9 , further comprising:
after receiving the token, waiting for an authorization from the instant message server prior to a creation of the offline session.
15. The method of claim 9 , further comprising
forwarding a consent, to the instant message server, to automatically initiate the offline session based upon at least one factor.
16. The method of claim 15 , wherein
the at least one factor is selected from the group consisting of: identity of the second computer client, a security level of the second computer client, and a predefined performance metric associated with the instant message server.
17. The method of claim 15 , wherein
the consent is an advanced consent.
18. The method of claim 1 , wherein
the request for the offline session is received while the first computer client is connected to the second computer client via the instant message server.
19. The method of claim 9 , wherein
the token is received while the first computer client is connected to the second computer client via the instant message server.
