Embodiment
Basic conception of the present invention is, when fused business (peer to peer session or message) is initiated, system generates convergence service session mark, and the convergence service session of generation mark is sent to source client and object client respectively; Source client and object client, in the follow-up reciprocal process of this fused business, all carry described convergence service session mark.
System can generate convergence service session mark according to the information of the information of the client of the business of initiation and object client, or stochastic generation one parameter identifies as convergence service session, or choose other certain several information and jointly generate convergence service session mark, as long as ensure that the convergence service session mark generated can this convergence service session of unique identification.
Further, said method can comprise the following steps:
Step one, convergence service user A sends fused business request message to user B;
The business this time initiated can be merge session service or converged message service, also likely initiates these two kinds of business simultaneously.Herein, messaging service and session service are referred to as convergence service session.
Here user B both convergence service user may also be non-fused service-user.
Step 2, generates convergence service session mark according to convergence service user A client address and user B client address;
This convergence service session mark is for identifying this convergence service session.The generation method of this convergence service session mark can have a variety of, such as, adopt simple compound mode, or utilizes certain algorithm of the prior art to calculate acquisition.
While generation convergence service session mark, status indicator can also be set for it, as active state or resting state.When a side of convergence service session exits, this convergence service session is in resting state.
Step 3, fused business request message is sent to customer end B, carry convergence service session mark in request message, and when the response message from session establishment to customer end A or message transmission that send successfully respond, carry above-mentioned convergence service session mark in the response message;
Step 4, after customer end A and customer end B receive convergence service session mark, in the follow-up reciprocal process of this fused business, all carries described convergence service session mark.
If terminal preserved converged message service content or merge session service information, then use the convergence service session Identification this time convergence service session received, and this business tine is identified with described convergence service session associate.
Due in next generation network, multiple terminals of a user can adopt same address, and therefore when user's switching terminal, if address is constant, then convergence service session mark is constant.If address change, former convergence service session mark is known constant as principal mark, the auxiliary mark of convergence service session is become with the address architecture of another client with new fused business address after switching, and can arrange convergence service session principal mark know be in resting state, the convergence service session of the auxiliary Identification of convergence service session is placed in active state, and this is carried to identification information (principal mark is known and auxiliary mark) and switches rear new terminal address in handover success response.
If object client is provided with preset value information, the preference that described preset value information comprises user is arranged, such as: the address that user is arranged After Hours is the landline telephone of family, and the information being at this moment sent to office telephone will redirect on landline telephone.When the preset information of client comes into force, need message and/or session request to redirect to other addresses, the principal mark of convergence service session is known constant, if turn to rear address not to be fused business address, then existing convergence service session is arranged to resting state; If turn to rear address to be fused business address, then do not turn to the address of client to generate auxiliary mark according to this new address and another, and the convergence service session that can arrange this auxiliary mark expression is active state.
Said method can utilize existing equipment to complete, and as session control center, or arranges separately a device at network side, carries out generation and the distribution of convergence service session mark, but need ensure that the message that all client terminals send or receive all needs through this device.Described device as shown in Figure 1, comprising:
Fused business service module: for managing fusion session and messaging service, generate the convergence service session mark of each session, in case of need, convergence service session mark is kept in convergence service session memory module, and transmission convergence service session is identified to each client;
Convergence service session memory module: the historical information of preserving convergence service session, and preserve convergence service session mark (comprising principal mark to know and auxiliary mark), for user's subsequent query;
The convergence service client be connected with described device: for realizing messaging service and session service alternately with fused business service module, and according to the corresponding message content of convergence service session identified query and session content;
In convergence service system as shown in Figure 1,101 and 105 modules are two client modules A1 and A2 of user A, A1 with A2 address is different, the client modules B (in figure 104) of user B, fused business service module 102 is for the message between leading subscriber A and user B and session interaction, and convergence service session memory module 103 completes convergence service session historical information for fit module 102 and preserves.The present embodiment is all that convergence service user is described for user A and user B, and user A and user B carries out message and session interaction through convergence service system.
Under point-to-point mode, converged message service flow process as shown in Figure 2, comprising:
Step 201: the terminal A1 of user A sends message to user B;
Step 202: the address according to two clients generates convergence service session mark, carries convergence service session mark in the request message sending to user B, carries convergence service session mark and return to terminal A1 in the response message of request message;
If need to adopt big message pattern to transmit message, then in session establishment response, carry convergence service session and identify to A1 terminal, in session request, carry convergence service session mark;
Step 203: after terminal A1 receives response message, take out identification information wherein, and the request message of setting correspondence belongs to the convergence service session that this mark represents, namely the convergence service session Identification this time convergence service session received is used, and this business tine is identified with described convergence service session associate, terminal B takes out identification information from the request message received, and sets the convergence service session that this asks to belong to this mark expression;
If terminal does not preserve the operation that message content just need not perform association.
Step 204, in the follow-up reciprocal process of this converged message service, all carries described convergence service session mark;
Merge session service flow process under point-to-point mode as shown in Figure 3, comprising:
Step 301: terminal A1 sends session establishment request to terminal B;
Step 302: the address according to terminal A1 address and terminal B generates convergence service session mark, carries convergence service session and identify to user B in session request, and in session success response, carry convergence service session identify to terminal A1;
If find had convergence service session to identify, then directly this convergence service session mark can be sent to terminal B, and send to terminal A1 in the response, but if terminal can store convergence service session mark, then also can no longer send.The convergence service session that this convergence service session mark represents can be in active state simultaneously.
Step 303: after user B terminal receives session establishment success message, take out mark, and the message identification this session received is a part for convergence service session, A1 terminal takes out session identification from the response message received, and is a part for convergence service session by the message identification received in this session;
Step 304: in conversation procedure, when user A carries out terminal switch between terminal A1 and A2, replaces A1 and user B terminal to carry out message and/or session with terminal A2 completely;
Step 305: when terminal switch, the address of foundation A2 terminal address and terminal B generates the auxiliary mark of convergence service session, principal mark knowledge and auxiliary mark are returned to A2 terminal, wherein master is designated original convergence service session mark, and the session arranging auxiliary mark is active state, the convergence service session mark of user B does not change;
Step 306:A2 terminal is a part for the convergence service session that major-minor mark represents with the session that major-minor mark arranges foundation;
When the preset information of user B comes into force, need to send to the message of user B and session request to redirect to another address, if this address is not fused business address, then do not need to generate auxiliary mark, otherwise, generate auxiliary identification information according to source address and the new address that turns to, principal mark to be known and auxiliary mark sends to source address and new turns to address, if the session that auxiliary mark represents is in resting state, be then set to active state, it is still original mark that principal mark is known.
Step 307: in the follow-up reciprocal process of this fusion session service, all carries described convergence service session mark.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the present invention.
Other information of the client except address such as can be utilized to generate convergence service session mark.
