Instant Messaging(IM) is a service on mobile phones, tablet PCs and computer to send and receive text, picture, audio clips, video clips via a network; it is one of the common applications on internet.

The popular Instant Messaging(IM) services includes: WeChat, QQ, Skype, RTX(Real Time eXpert), e-contact and others. The first three players targeted for public users; while the remaining two players targeted for users from enterprises or organizations.

In light of the rapid development of the internet and customer needs, collaborations from enterprises or organizations have increased tremendously, and many are international based. As the result of its high efficiency and flexibility, Instant Messaging(IM) has gained acceptance and its usage surged amongst enterprises and organizations. In the enterprise Instant Messaging(IM) environment, the following needs arise:

(1) , To ensure the privacy and confidentiality of enterprise Instant Messaging(IM), enterprise needs to have its own private Instant Messaging(IM) server;

(2) , To be able to connect Instant Messaging(IM) with other enterprises, different Instant Messaging(IM) system needs to interconnect and communicate.

Currently most Instant Messaging(IM) system is using "Client layer + Server layer", a two layer structure that represent the Instant Messaging(IM) server and Instant Messaging(IM) client software. There are two types of commercial Instant Messaging(IM) services on the market:

Large scale Instant Messaging(IM) network targeting public users, for example: WeChat and QQ.

Small scale Instant Messaging(IM) network targeting internal users of enterprise or organizations, for example: RTX(Real Time eXpert); but Instant Messaging(IM) system of various enterprises or organizations are unable to interconnect, not to mention the challenge to connect to the Instant Messaging(IM) network that targeting public users. e-contact is an Instant Messaging(IM) service platform that targets small organization or enterprise, features one main controller and a backup controller, allowing different enterprise or organizations' users to connect Instant Messaging(IM) on this common platform, but enterprises or organizations can't have their own private server.

Another possible solution is to provide protocol converter gateway for different Instant Messaging(IM) system, but this can only solve the connectivity between two Instant Messaging(IM) systems, it is unable to resolve issue on multiple systems.

Clearly the current commercial Instant Messaging(IM) systems available on the market still not able to satisfy and fulfill the needs of the 2 types of users mentioned above on enterprise application of Instant Messaging(IM), as well as solve the interconnect and privacy issue.

FIG.2 is the System deployment diagram of the invention - A new Instant Messaging(IM) system, it shows a typical system application and deployment scenario.

(1) Enterprise A has used "Server" on their private Instant Messaging(IM) server SI, S2, and S3 in their intranet; Intranet user C1,C2 to C6 has used "Client" to create and login their account respectively in the 3 servers mentioned above, to access Instant Messaging(IM) and various enterprise application services.

(2) Enterprise B has used "Server" on their private Instant Messaging(IM) server S4, and S5 in their intranet; Intranet user C7, C8 to CI 3 has used "Client" to create and login their account respectively in the 3 servers mentioned above, to access Instant Messaging(IM) and various enterprise application services.

(3) Instant Messaging(IM) service provider has deployed "Server" on their Instant Messaging(IM) server targeted for public users S6, S7, S8 and S9; Public user C14, C15 to C21 has used "Client" to create and login their account respectively in the 4 servers mentioned above, to access Instant Messaging(IM) and various enterprise application services. (4) Cloud service provider deploys "Server" to its Instant Messaging(IM) server S10, Sll, S12 and S13, ready to provide its client the service to establish dedicated Instant Messaging(IM) server.

(5) Utilizing "Router", equipment vendor established Router Rl, R2, R4, and R5, building core backbone routing service network, providing addressing service for the servers of various enterprise and organizations.

The usage of the Instant Messaging(IM) system can be illustrated in the following scenarios:

1. Instant Messaging(IM) that does not require network address routing

This applies to internal Instant Messaging(IM) and relevant enterprise application within the enterprise or organization, establish internal Instant Messaging(IM) server to complete the system without the need to get through core backbone routing service network: For example, The Instant Messaging(IM) among the CI, C2 to C6 users in Enterprise A, only required to access their private Instant Messaging(IM) server SI, S2 and S3;

The Instant Messaging(IM) among the C7, C8 to C13 users in Enterprise B, only required to access private Instant Messaging(IM) server S4, and S5;

The Instant Messaging(IM) among the Public user C14, CI 5 to C21, only required to access public Instant Messaging(IM) server SI, S2 and S3

2. Instant Messaging(IM) that requires network address routing

Instant Messaging(IM) across various enterprises or organizations and between public service users and enterprise intranet users will require the network address routing from the core backbone routing service network, to interconnect with Instant Messaging(IM) server, in order for all the users to connect Instant Messaging(IM).

For example, When User CI and C2 from Enterprise A, User C8 and C9 from Enterprise B, and Public user C20 and C21 connect a group messaging, their Instant Messaging(IM) server SI, S5 and S9 will require network address routing from their associated router Rl, R2 and R4 in order to connect, then the users can connect Instant Messaging(IM).

The network address routing processes are as follows:

a) Assuming User CI initiate group messaging, then the Server SI that CI logged-in will be responsible in seeking the server network address of other users.

b) CI will send network address routing request to Rl, based on the routing request of the target server identification data, conduct routing in the core backbone network routing service according routing policy.

c) When Router R2 and R4 received the address request, it will respond to Router Rl on the network address of Server S5 and S9, after that Router Rl will respond to Server SI on the network address of Server S5 and S9.

d) Finally Server SI will establish network connection with Server S5 and S9 base on the network address received from feedback, group messaging starts.

3. Instant Messaging(IM) that requires dedicated server

Cross enterprise or organizations Instant Messaging(IM) that has higher demand in privacy, and Instant Messaging(IM) in between public users and enterprise or organizations ' users, can lease an Instant Messaging(IM) server from cloud service provider, creating a dedicated Instant Messaging(IM) server for a specific project, task or user group;

For example: To manage a collaborative project,

User C5 and C6 from Enterprise A, User CIO, Cll and C12 from Enterprise B, Public user C17 and C18, can lease Instant Messaging(IM) server Sl l from cloud service provider, Assigning Server Sll as the dedicated server for the project, create and add new accounts; The additional advantage for this method is that all instant messages can be audited, and be able to completely track the status of the collaborative project.
