Description

A method and system for adding users in a group conversation

technical field

The present invention relates to the field of communication technology, in particular to a method and system for adding users in a group conversation.

Background technique

PoC (Push to talk over wireless service) is a group call service that supports 1-1 and 1-M calls. When initiating a call to a group, the call can be initiated from a URI (Uniform Resource Identifier) list; Initiate a call through the ID of a defined group; the defined group includes not only the members of the group, but also the access policy of the group, that is, the rights to initiate sessions and invite people to join sessions are limited; all The group definitions described above are stored in the XML document management server XDMS.

The defined groups are further divided into predefined groups and chat groups. The differences between the two groups are reflected in the following aspects:

1) When initiating a predefined group session, it is necessary to invite group members to join the session, that is, the group members will receive a session request; for chat groups, the group members are not invited to join, that is, the group members will not A session request is received;

2) When adding a user to an existing session, only members of the group are allowed in the predefined group, anyone can be added to the non-restricted chat group, and only members of the group are allowed to join the restricted chat group.

The current process of adding a user to a session is as follows:

(1) Send a request to the server to join the user in the session;

(2) The server judges whether the person who initiates the request has authority, and whether the person to join the predefined group and the restricted chat group is a group member;

(3) If all are satisfied, a request to join the session is sent to the person to be joined, and the user to be added responds and accesses the session.

The server checks through the session policy definition whether the user to be invited to join should be invited, and if so, sends a session request to the user to be invited. The specific implementation of this process in the prior art is:

In the group member definition document, besides the group member definition, it also contains a rule set, which represents the authorization policy of this group. A rule set consists of 0 or more rules, and each rule consists of a condition subitem and an action subitem. The condition subitem is used to define or describe a set of user IDs; the behavior subitem is used to describe what permissions members in the user set have, such as being able to initiate a session, add users to a session, and allow to join a session during a session, etc.

As mentioned above, in the prior art, for all users who have the authority to add users to the session, during the process of adding users, either anyone can be added to the session, or only group members can be added to the session. In fact, because of the content or topic of the conversation or the progress of the conversation, for a restricted group, such as a predefined group or a restricted chat group, it is sometimes necessary to add a user outside the group To join a session, for example, during the discussion of a certain topic in the restricted group A, another expert who does not belong to the group A needs to be invited to participate in the discussion, which cannot be achieved by using the existing system.

Contents of the invention

The purpose of the present invention is to provide a method and system for adding different types of users to a session.

The purpose of the present invention is achieved through the following technical solutions:

A system for adding users in a group conversation, including a server end, a document management server XDMS end and multiple clients, the XDMS end including:

Invitation authority limitation module, used to store the authority of the client that is connected to the server to invite members, set the authority to invite different types of users for different clients; said authority includes: can not invite users to join, can invite group members to join, can Invite non-members to join, or can invite all users to join.

The system also includes:

The group ID parsing module is used for parsing the group ID sent by the client, and parsing the group members through the local database or XDMS according to the ID.

The group ID parsing module is set on the server side.

A method for adding a user in a group conversation, comprising:

A. During the session, the client initiates a request to add users to the session. The client is pre-set with permissions to invite different types of users. The permissions include: cannot invite users to join, can invite group members to join , can invite non-members to join, or can invite all users to join;

B. The server invites the user of the type to join the session according to the invitation authority of the client.

The request message includes: the address or address list of the user to join the session, or one or more group identifiers, and the session identifier to add the user to the specific session.

When the client invites users to join in a group, the step B further includes:

The server parses the users included in the group corresponding to the group ID, and parses out the Uniform Resource Identifier URI of the user to be added to the session. Define the group, and then calculate the union of all users to be invited.

Described step B specifically comprises:

If the client has the authority to invite users of the type and the user to be added is a user of the corresponding type, the server sends the request to the user to be added;

If the user to be added accepts the invitation, a response message is sent to the client.

The method is applicable to PoC business and group conversation system.

It can be seen from the above-mentioned technical solution provided by the present invention that the present invention makes it more flexible to add users during the session by setting the permissions for different session participants to add different types of users to the session. In the case of restricted groups Now, you can talk to non-group members without reinitiating a session.

Detailed ways

The core idea of the present invention is to provide a method and system for adding users in a group conversation, and set permissions for adding different types of users to the conversation for different conversation participants, so that adding users in the conversation process is more flexible.

The present invention provides a system for adding users in a group conversation. The system includes a plurality of clients, a server and an XDMS. The schematic diagram of the system is shown in FIG. 1, and the XDMS includes at least an invitation permission limiting module; The server side at least includes a group ID parsing module;

The invitation authority limitation module is set in the rule subitem, and is used to store the authority of the invited members of the client connected to the server, and set the authority of inviting different types of users for different clients; the rules of the group conversation policy can be The behavior subitem in the subitem is decomposed into two, one is used to describe the permission to invite members, and the other is used to describe the permission to invite non-group members; the permissions include: cannot invite users to join; can invite group members to join ; Can invite non-members to join; Can invite all users to join;

The group ID parsing module is used for parsing the group ID sent by the client, and parsing out group members through a local database or XDMS according to the ID.

The present invention provides a method for adding users in a group conversation, which is suitable for PoC services and any group conversation system, such as IM (instant message), and its operation flow is as shown in Figure 2, specifically comprising the following steps:

Step 1: During the session, client A initiates a request to add a user to the session;

Client A can request to add one or more users to join the session in the form of the user's URI or URI list, and can also initiate an add request to the server in the form of one or more group IDs, that is, the way client A initiates the request Can be: 1 user, a list of multiple users, 1 group ID, multiple group IDs, or one or more groups plus one or more users;

The request includes the address of the user to join the session, or a list of addresses, or one or more group identifiers, and the session identifier to add the user to the specific session;

Step 2: If the server receives the request, it sends a response message to the client A to confirm that the server has received the request;

Step 3: The server side judges the invitation authority of client A and the type of the invited user;

The server side checks the authority of the client A to determine whether it has the authority to invite the user of the type, and whether the invited user is a user of the corresponding type;

For the situation that contains group ID, the group ID analysis module of server end finds out the URI of the user to be added in the session by obtaining the group definition from XDMS, and resolves which users are included in the group corresponding to the group ID; For the case of multiple group URIs, the server first obtains the definition of each group, and then obtains the union of all users to be invited;

Step 4: If it is determined that the client A has the right to invite the user of the type, and the user to be added is a user of the corresponding type, the server initiates a session joining request to the user to be added;

Step 5: If a member joins, notify client A that the called user has joined;

Step 6: After receiving the response message, the client sends a confirmation message to the server, and the operation of adding members during the session is completed.

In the following, the method is applied to the PoC service as an example to illustrate, as shown in FIG. 3 ,

During the session, when user A needs to add other users to the session, the PoC server A sends a request to add members to the control server X; the PoC server can implement group policies for adding users to the session. The request includes: the PoC address, or address list, or group ID of the user to be added to the session, or a plurality of group IDs and a session ID to add the user to a specific session;

In Fig. 3, step 1-5 is that PoC server A sends to control server X an add member request that bears the information of the user to join the session; step 6-10 is that control server X sends a response from PoC server A, indicating that the request has been accepted Accept; after the control server X accepts the request, determine whether the client A has the authority to invite members of the type, and whether the invitee is a user of the corresponding type; The parsing module finds out the URI of the user to be added to the session by obtaining the group definition from XDMS, and parses which users are included in the group corresponding to the group ID; for the case of multiple group URIs, the server first obtains The definition of each group, and then seek the union of all users to be invited; if the client A and the invitee meet the conditions, then the control server X sends an invitation to the user to be invited to join the session; steps 11-15 are only invitations When there is a single user, after the control server X receives the acceptance response of the user to be added, it notifies the PoC server A to join the member to be added; the steps 16-20 are that the PoC server A sends back a confirmation message to the control server X after receiving the notification, Indicates that the notification has been received, and the process of adding users to the PoC service is completed.

To sum up, the present invention makes it more flexible to add users during the session by setting permissions for different session participants to add different types of users to the session. In the case of a restricted group, there is no need to re-initiate a Conversation, you can talk with non-group members.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
