Embodiment
In order to solve in the present instant communicating system, searching user profile efficient reduces, the subscriber information management server load is big, problems such as user's online information management of performance deterioration, on access server, set up user's good friend's table and reverse good friend's table, user and the associated person information thereof that inserts this machine managed, during searching user's information, directly on access server, search.
The present invention is described in detail below in conjunction with accompanying drawing.
Consult shown in Figure 1A, the communication system in the present embodiment comprises a plurality of access servers, and a plurality of login user clients that are connected with access server by network.
Each access server is used to obtain the associated person information of login user and preserve, and notifies other access servers with the user profile of described login user; And at local search user's associated person information with transmit instant message.
Described login user client inserts instant communicating system by access server, finds associated person information from access server, and transfers immediate news to the contact person by access server.
When the user logins, be connected on the access server in the system, many access servers are formed a UDP (User datagramprotocol, User Datagram Protoco (UDP)) multicast group, each station server in the group can be received the multicast UDP information of other servers transmissions that insert in the group.
On access server, set up and be used to reverse good friend's table of storing good friend's table of user's friend information and being used to store the customer reverse friend information, related at the friend information of this locality by user ID in described good friend table with this user, related with this user's reverse friend information and write down this user position information by user ID in described reverse good friend shows.
Good friend's table and reverse good friend's table all adopt user's ID to make index.Oppositely the good friend is meant and adds the user of user for the good friend, as A B is added to the good friend, and then B is the good friend of A, and A is the reverse good friend of B.Good friend's table is used for searching the friend information of certain user on this server.Good friend's list structure comprises the node of user ID ID in good friend's table shown in Figure 1B, the buddy list recording user of each node correspondence is at the friend information of this locality.
During the good friend of inquiring user on server, this user's of inquiry node can find the friend information of user on this machine corresponding to this nodes records in good friend's table of this server.
During each user login services device, obtain this user's reverse friend information, in good friend's table of the server that the user inserts, this user profile is recorded in the buddy list of its reverse good friend's node.For example: user A is the good friend of user B and user C, when user A inserts instant communicating system by server A, from database, find the reverse good friend user B of user A and the ID of user C, the information of user A is recorded in the buddy list of user B node and user C node in the server A good friend table, recording process is: search user B node in good friend's table of server A, if user B node does not exist, in good friend table, set up user B node, and in the buddy list of user B node the information of recording user A; In good friend table, search user C node, if user C node exists, the direct information of recording user A in the buddy list of user C node.Like this, when the user A log-in instant communication system, the information of user A has been recorded on the server A in the buddy list of user B node and user C node in good friend's table.
Oppositely good friend's table is to be used for searching certain user by which user of book server to be added as a friend, oppositely good friend's list structure is shown in Fig. 1 C, the node and the residing POS of user (the Position of Server that in oppositely the good friend shows, comprise user ID ID, server location information), the list records user of each node correspondence is at the reverse friend information of this locality.
The node of inquiring user can find reverse friend information and this user residing server location information of user on this machine corresponding to this nodes records in reverse good friend's table of this server.
During each user login services device, obtain this user's friend information, in reverse good friend's table of the server that the user inserts, this user profile is recorded in the reverse buddy list of its good friend's node.For example: user A is the reverse good friend of user B and user C, and user A inserts in the instant communicating system by server B by server A, user B, and user C is not online.When user A inserts instant communicating system by server A, from database, find the good friend user B of user A and the ID of user C, the information of user A is recorded in the reverse buddy list of user B node and user C node in the reverse good friend's table of server A, recording process is: search user B node in reverse good friend's table of server A, if user B node does not exist, oppositely setting up user B node in good friend's table, and the residing POS of recording user B is server B, the information of recording user A in the reverse buddy list of user B node; Oppositely searching user C node in good friend's table, if there is user C node, the residing POS of user C is recorded as sky, and in the reverse buddy list of user C node the information of recording user A.Like this, when user A log-in instant communication system, user A is the reverse good friend on server A as user B and user C, be recorded on the server A in the buddy list of user B node and user C node in reverse good friend's table, simultaneously, the residing server location information of user B and user C has also recorded in reverse good friend's table.
Consult shown in Figure 2ly, the processing procedure during subscription access server is as follows:
The user A of step 201, access server A sends log messages to server A.
Step 202, server A are obtained good friend ID and the reverse good friend ID of user A from database.
Step 203, server A with the good friend ID of the user A that gets in the database and oppositely good friend ID return this machine.
Step 204, according to good friend's ID, in reverse good friend's table of server A, find good friend's node, the information of user A is recorded in the reverse buddy list of good friend's node; According to reverse good friend's ID, in the good friend of server A table, find reverse good friend's node, the information of user A is recorded in the buddy list of reverse good friend's node.
Step 205, server A send reaching the standard grade when notifying of user A for the reverse good friend of user A in this machine, inquiring user A in reverse good friend's table of this machine, and if there is no user A node shows the reverse good friend who does not have user A in this machine, does not deal with; If there is user A node, in the reverse buddy list of user A node, user A server info of living in is revised as server A, and in the reverse buddy list of user A node, finds reverse good friend ID.
Step 206, server A send the user A notice of reaching the standard grade for corresponding user according to the reverse good friend's who finds ID.
Step 207, server A send reaching the standard grade when notifying of user A for other access servers, and server A is UDP multicast user A on-line message in instant communicating system.
After access server B in step 208, the instant communicating system receives multicast message, inquiring user A in reverse good friend's table of this machine, if there is no user A shows the reverse good friend who does not have user A in this machine, does not deal with; If there is user A, execution in step 209.
Step 209, the residing server location information of user A in the reverse good friend table of server B is revised as server A, in the reverse buddy list of user A node, finds reverse good friend ID.
Step 210, server B send the user A notice of reaching the standard grade for corresponding user according to the reverse good friend's who finds ID.
Adopt the above processing, after the user A login system, in the server that user A inserts, preserved the information of user A and the associated person information of user A in the instant communicating system; The reverse good friend of user A has obtained the information of user A simultaneously.
Consult shown in Figure 3ly, behind the user A login communication system, the processing procedure of searching good friend's online information is as follows:
Step 301, user A logon server A.
The node of step 302, server A inquiring user A in good friend's table of this machine, find the good friend ID that writes down in the buddy list of this node, according to good friend ID, find good friend's node at reverse good friend's table, to be revised as server A corresponding to the server info of this nodes records, and check good friend's online information.
Step 303, server A return to user A with good friend's online information of user A in this machine that finds.
Good friend's online information of step 304, server A multicast request user A in instant communicating system.
After server B in step 305, the instant communicating system was received multicast request, the node of inquiring user A checked whether this machine exists the good friend of user A in good friend's table of this machine, if there is execution in step 306; Otherwise, do not deal with.
Step 306, server B send to server A with the online information of the good friend of user A in this machine.
The friend information of the user A that step 307, server A are returned according to server B is recorded as server B with the residing server location information of the good friend of user A on server B in the reverse good friend's table of this machine.
Good friend's online information of the user A that step 308, server A will receive from server B returns to user A.
Consult shown in Figure 4ly, the processing procedure that user online status is changed into stealthy login is as follows:
The user A of step 401, access server A will go up line states and become stealthy message and send to server A.
Step 402, server A with good friend's table of this locality and oppositely in good friend's table the state recording of user A be stealthy login.
Whether the inquiry in reverse good friend's table of this machine of step 403, server A exists the node of user A, if there is this node, finds reverse good friend ID in the reverse buddy list of this node, and execution in step 404 then; Otherwise, do not deal with.
Step 404, server A send user's A condition change information for corresponding user according to the reverse good friend's who finds ID.
Step 405, server A multicast user A in the instant communicating system status change message of reaching the standard grade.
After server B in step 406, the instant communicating system is received multicast message, whether inquiry exists the node of user A in reverse good friend's table of this machine, if exist, in the reverse buddy list of user A node, find reverse good friend ID, execution in step 407 then; Otherwise, do not deal with.
Step 407, server B are recorded as server A with the residing server location information of user A in reverse good friend's table of this machine.
Step 408, server B send user's A condition change information for corresponding user according to the reverse good friend's who finds ID.
Consult shown in Figure 5ly, the processing procedure that the user A of access server A sends message for good friend user B is as follows:
When step 508, server B receive the message of server A forwarding, search the connection that whether has user B, if there is execution in step 509; Otherwise, execution in step 511.
Carry out this step, avoided working as just in time off-line of user B, when the user B information of preserving in the server B was not also upgraded, server B was sent message for user B and causes information drop-out.
The message that step 509, server B are transmitted server A sends to user B.
If user B is not the good friend of user A, but with having the user to add user B among the user that server A is connected is the good friend, when having user B information in reverse good friend's table of server A, the processing that user A sends message for user B is identical with the above processing procedure.
Consult shown in Figure 6ly, when user B is not the good friend of user A, do not have user B information in reverse good friend's table of server A, the processing procedure that user A sends message for user B is as follows:
Consult shown in Figure 7ly, the processing procedure that the user logs off is as follows:
The user A of step 701, access server A sends to server A with the message of logging off.
Whether the inquiry in reverse good friend's table of this machine of step 702, server A exists the node of user A, if there is this node, finds reverse good friend ID in the reverse buddy list of this node, and execution in step 703 then; Otherwise, do not deal with.
Step 703, server A send the user A information of logging off for corresponding user according to the reverse good friend's who finds ID.
Step 704, server A according to the reverse good friend's who finds ID at good friend's table of this machine and the reverse corresponding node of inquiry in good friend's table, inquire corresponding node after, will be corresponding to the information deletion of the user A of nodes records; Simultaneously user A server info of living in the user A node in reverse good friend's table is emptied.
Step 705, server A multicast user A in the instant communicating system message of logging off.
After server B in step 706, the instant communicating system is received multicast message, whether inquiry exists the node of user A in reverse good friend's table of this machine, if exist, in the reverse buddy list of user A node, find reverse good friend ID, execution in step 707 then; Otherwise, do not deal with.
Step 707, server B empty the residing server location information of user A node in reverse good friend's table of this machine.
Step 708, server B send the user A information of logging off for corresponding user according to the reverse good friend's who finds ID.
