Steps A, the current local domain management and group server of user's place client login, local domain management and group server is classified by user identifier, distinguishes local intra domain user and outer region roamer, and preserves active user's logging status;
Step B, client login local territory, group creator place management and group server, set up new group by interacting message on local domain management and group server, local domain management and group server is carried out group and is set up operation, is maintained in simultaneously the group member information of the local group that sets up and local access;
Step C, for the group that has been successfully established, in network, the member in each territory can apply for adding, and comprises that the user initiatively applies for adding with management and group person or group creator to invite the two kinds of situations that add.
Described steps A further comprises:
A1, user send log messages to local domain management and group server, content comprises user ID identifier, the pet name, logging status (online, stealthy) etc., at first local domain management and group server belongs to local user or outer region roamer according to ID identifier judgement user, preserve active user's logging status, log messages is as shown in table 1 below:
Table 1
| User ID | User's pet name | The ID of group to be logined | User's logging status | Extension |
A11, for the local user, current local domain management and group server will be in local data base direct this user of inquiry place group information, then form the information list (comprising the user current login member of each group of place list, each member's logging status information and group's announcement information list etc.) of the affiliated group of user, return to the login result; While local domain management and group server update user logging status.
A 12, for outer region roamer, at first current local domain management and group server is inquired about to the management and group server in this territory, user place, and Query Result is formed the information list (comprising the user current login member of each group of place list, each member's logging status information and group's announcement information list etc.) of group under the user, return to the login result; The method of inquiry adopts universal distributed querying method, for example, based on the distributed algorithm etc. of searching of DHT framework, while local domain management and group server update user logging status.
A2, current local domain management and group server feed back to login user with the information list that this user logins result and groups of users; The information that in management and group server notification this group under this group, other members have the member to login simultaneously, the current login user list so that other users upgrade in time.
Described step B further comprises:
In the present invention, the management and group server in each territory only is in charge of the essential information of the group that sets up in local domain and the user profile of logining at local domain; Wherein, the user who has same domain identifier (as IP address prefix, SIP domain addresses symbol or other relam identifiers) with local domain management and group server is the local user, other users are the nonlocal user that outer region roams into this place login group group management sever, management and group server in local domain is only safeguarded local user's essential information, does not safeguard outer region roamer's personal information.Further supplementary notes is, only has the local user could carry out group in local domain and sets up operation, for the nonlocal user who roams into other territories, to set up in other territories the authority of group.
Described step B further comprises:
B1, group creator send the message packet that creates group, and wherein message information comprises the attribute information of the group that creates, and comprises that the character of group creator ID, group name, group, group set up purposes etc.; Wherein the character of group further comprises whether being interim group or normal group: for interim group, also need further to indicate T life cycle of interim group, in interim group, all members are the interim member of group, after life cycle T, all information of interim group will be deleted from the management and group server automatically, and its temporary group member information also will no longer be preserved subsequently; Corresponding is normal group with it, and without time restriction life cycle, until group creator deletes it, the message packet content that concrete group sets up is with reference to following table 2:
Table 2
At first B2, local domain management and group server parse relevant groups information after receiving the message packet of this establishment group, then carry out group and set up operation, and then relevant groups information is kept in local data base; To set up different database storage item for the interim group that mentions in step B1 and normal group, for interim group, T referred to when this group sets up and added up life cycle, after T hour, this group's life span expires, local domain management and group server will be deleted the information of interim group automatically this moment, and no longer preserve the information about firms in this interim group;
The relevant groups information of above mentioning refers to that group sets up group name contained in message packet, group's character, group creator ID and extension information.
B3, local domain management and group server reply group creator group and set up acknowledge message, comprise group in this message packet and set up result; For the groups operation that success creates, the ID that also further comprises the character of group and distribute to this group in this message packet.Be the interim interim ID of group of group allocation; The message packet form is with reference to following table 3:
Table 3
| Group sets up result | Group name | The character of group | The ID of group | Extension |
The management and group server of (being the territory beyond user's place client local domain of living in) sends the notification message that new group sets up to other territories by network for B4, local domain management and group server, content comprises the character of the title, the ID of group, group creator ID, the place field managing server ID of group and the group that newly set up group etc., each other field managing servers notify immediately administer group user in the territory, user friendlyly search and add.Similarly, for newly-established interim group, this notification message also comprises T life cycle of interim group; The message packet form is with reference to following table 4:
Table 4
For the group that sets up and have the user to add, often online whether group creator will specify some management and group persons according to user's actual conditions (, in group speech number of times etc.), facilitate subsequent user to add; The user who has added also can initiatively apply for being management and group person.
Described step C further comprises:
Group adds the member, and is different according to the invited party of adding member's operation, and the member adds can be divided into following dual mode:
1, the user accords with applying for adding group according to group's special sign;
2, management and group person initiatively invites a certain user to add this group;
Be directed to the 1st kind of member's addition manner, carry out following operation:
C1, user place client sends to local domain management and group server the message packet that group adds application, comprise user ID in this message packet, application adds the ID of group, application to add the reason of group and user's the essential informations such as authority, the message packet content is with reference to following table 5:
Table 5
| User ID | Application adds the ID of group | The application user right | Application adds the reason of group | Extension |
Be directed to the group type of mentioning in steps A, the user initiatively applies for adding group can be divided into following two kinds of situations:
If a) the user application group that adds is interim group, the user adds the interim Member Users who is after group in interim group so, enjoys interim group service and member's authority temporarily;
B) if the group that user's application adds is normal group, can be divided into again following two kinds of situations when the user adds group so:
B1, user can apply for adding a normal group temporarily, this moment, the user was a casual user of this normal group, this moment, the management and group server of management and group person and corresponding domain was only this login service of this user, namely authorize this user to enjoy partial function temporarily, as forward this user and send partial sharing resource of group message, temporary visit part group etc.; After treating that this user logs off, the management and group server of corresponding domain automatically in the user list of safeguarding with its deletion;
B2, a kind of situation are a normal users of normal group for user's application, and this moment, the user enjoyed the open all functions of normal group.
C2, local domain management and group server receive the message packet that user's application adds group, therefrom obtain corresponding application and add the information such as the ID of group, at first search to judge at local domain whether this group creates and management as local domain management and group server;
C21) if being local domain management and group server, the group that application adds creates and management, local domain management and group server will preferentially be retrieved the member who whether has this management and group person in other group members in local domain, if existence and this management and group person are online, this application is added the message of group to be sent to this management and group person, this management and group person receives that this application adds and carries out corresponding confirmation after the message of group and process; If there is not this management and group person in this territory, this application is added the message of group to issue group creator, add the message of group to process by group creator to this application, turn step C3.
C22) be that outer region management and group server creates and management if application adds group, local domain management and group server will find the management and group server in this territory, group place with the distributed enquiring method distributed algorithm of searching of DHT framework (for example based on) according to the ID of group, and next the operation of the management and group server in this territory, group place is with step C21) in the server operation of local domain management and group;
C3, management and group person or group creator are replied corresponding group and are added message, are forwarded to user in C1 through the management and group server of local or other input fields.Simultaneously, according to the suggestion of management and group person or group creator, management and group servers local or other input fields are done corresponding operating:
C31) if management and group person or group creator are agreed this user to add, the management and group server is carried out following respective operations: give the different authority of this user (as casual user or other) according to the result of user's application and management and group person's approval.simultaneously, differ and be decided to be territory, current management and group person place in the territory, group place that adds due to application, therefore, when the territory, group place that application adds is territory, management and group person place, this group member is added the further notice of acknowledge message to the management and group server in this territory, management and group person place, when the territory, group place that application adds is not territory, management and group person place, this group member is added the further notice of acknowledge message to the management and group server in territory, the creator of this group place, after the management and group server in the management and group server in this territory, management and group person place or territory, the creator of this group place receives this notification message, concrete outcome is added in the database of management and group server of corresponding domain, reply simultaneously group and add the user that success message application to the C1 adds group,
C32) if management and group person or group creator disagree with that the user adds, this management and group server is directly replied the user that refuse information application to the C1 adds group.
For C31) in management and group person or group creator agree the situation that the user adds, management and group person or group creator also need to send corresponding new user and add notification message to other each Member Users of this group.
Be directed to the 2nd kind of member's addition manner, carry out following operation:
C (1), management and group person are directly according to user ID, sending group adds invitation message to corresponding invited user, this group adds invitation message at first to be sent to local domain management and group server, then is sent to invited user by local domain management and group server.Differ and be decided to be territory, current management and group person place due to territory, invited user place, therefore, at first local domain management and group server judges whether invited user is this intra domain user.
C (11) is if directly send this application to invited user;
At first C (12) finds the management and group server in territory, invited user place if not according to user ID, then this group is added invitation message to send to this management and group server, and then be sent to invited user;
C (2), invited user reply corresponding group member and add acknowledge message, and the suggestion of reply comprises to be agreed or refusal, can further include the group member type (casual user or normal users) that the user that mentions in C1 adds.
The management and group server in C (3), territory, management and group person place receives invited user and sends the group member of returning and add acknowledge message.
C (31) if invited user adhere to, directly send this application to the management and group server in territory, management and group person place, the group member type that this management and group server adds according to user in C (2) is given the different authority of this invited user (as casual user or other).Simultaneously, carry out similar C31) step.
C (32) is if invited user is disagreed with to add, and the local user adds flow process and finishes.
Agree for management and group person in C (31) or group creator the situation that the user adds, management and group person or group creator also need to send corresponding new user and add notification message to other each Member Users of this group.
For above-mentioned situation, management and group person can have two kinds of selections, a kind of for invite the user to add temporarily, this moment, the management and group server in management and group person and territory, the corresponding creator of group place was only this login service of this user, namely authorize this user to enjoy partial function temporarily, as forward this user and send group message, partial sharing resource of temporary visit part group etc.; After treating that this user logs off, namely in the user list of safeguarding with its deletion; A kind of for inviting the user normally to add, enjoy the open all functions of group.
In addition, the user adds the situation that the user participates in certain group's activity infrequently that is directed to temporarily, and a user can add in the middle of a plurality of groups simultaneously temporarily.
Below each embodiment will be take the domain management system of SIP/SIMPLE agreement as the core session management protocol, the SIP/SIMPLE agreement is one of Next Generation Internet core session protocol, technical scheme of the present invention and its combine and have more universality and high efficiency.
As shown in Figure 2, paint in Fig. 2 and comprise 4 communication domain in core network, for the sake of simplicity, its domain name is domain1.com, domain2.com, domain3.com and domain4.com, and the management and group server S IP address in 4 territories is: GroupServer1@domain1.com, GroupServer2@domain2.com, GroupServer3@domain3.com and GroupServer4@domain4.com; In following examples, will be with management and group server S IP address, user's sip address as separately characteristic ID, be also user ID and management and group server ID, each territory is associated with similar overlay framework form, can carry out the address map locating as keyword with sip address mutually.
