Description
Technical Field
The present invention relates to the field of network communications, and in particular, to a method for processing information in a communication system.
Background
With the development of broadband networks, mobile communication will not be limited to traditional voice communication, and multimedia services combining multiple media types such as audio, video, pictures and text will gradually be developed. The multimedia service can be combined with data services such as presence, short message, WEB browsing, positioning information, PUSH, and file sharing, and provides various service services for users. The multiple business services include:
message service: instant messaging and chat rooms, multimedia short messages, etc.
Video service: entertainment, multimedia information, daily communication, etc.
E-commerce: product catalogs, search engines, shopping carts, order management, payments, and the like.
And (3) playing: single player games, group games, etc.
Positioning service: person finding, guidance, alarm, etc.
A personal assistant: address book, calendar, bookmark management, file storage, event reminder, email, etc.
Driven by the above-mentioned various business service applications, the 3GPP (third generation partnership project) standards organization introduced an IP-based IMS (internet multimedia subnetwork) architecture, aiming to implement various multimedia applications using a standardized open architecture in a communication network, providing users with more choices and richer feelings.
With the development of network technology, multi-party communication becomes a gradually popular service, and a uniform control point is inevitably needed to manage the system in order to realize multi-party communication, and the consistency and real-time performance of management need to be ensured. For example, when a user applies for sending audio data, the system needs to have and only has one control point to process the application. Current multiparty multimedia communication systems include PoC (push to talk over cellular) systems, Conference (multimedia Conference) systems, etc. Wherein the PoC system is a multiparty multimedia communication system that is centrally controlled.
In multi-party communication, there are situations where the user access situations are different, such as some users accessing through a WCDMA (wideband code division multiple access) system and some users accessing through GPRS (general packet radio service), in which case the user speed may not match.
In the prior art, a method for data transmission in a multi-party multimedia communication system is as follows: the session server caches the data which are sent by the calling user and need to be transmitted, and then transmits the data to different called users. And aiming at the called users with different access rates, the time required to be cached by the session server is different.
The above-mentioned method for data transmission in the prior art has the following disadvantages: since in a multiparty multimedia communication system the length of time a user can send data is limited and the receiving bandwidth of the individual called users is different. Therefore, this method may cause a large difference in the time delay of receiving data by different called users. When the called user can not receive the data forwarded by the session server within the time for sending the data specified by the calling user, the data sent by the session server to the called user has no meaning, and charging information is generated for the called user.
For example, in the data transfer process shown in fig. 1, the calling user sends the multimedia data to the called users 2 and 3 through the session server. When the calling user finishes sending data to the session server, a release request is sent to the session server, or the sending right of the calling user is overtime, the system stops the sending right of the calling user and simultaneously clears the cache of the calling user. At this time, the called user 2 may have finished receiving data, but the called user 3 may not have finished receiving data, and the part of data that the called user 3 has received is invalid.
In addition, when the sending right of the calling user is overtime due to the fact that the speed of sending the data is too slow and the sending of the data to the session server is not finished, the session server cancels the data sending right of the calling user by sending a message to the calling user and simultaneously clears the cache of the calling user. At this time, the data sent by the calling subscriber, which has been received by the called subscriber, is also invalid. A schematic diagram of this data transfer scenario is shown in fig. 2. Although the size of the data transmitted by the calling subscriber can be limited to avoid this, the ability of the calling subscriber to transmit data is not taken into account.

and 3-1, after the calling user selects a proper sending mode, sending session information to a session server, wherein the sent session information carries some related information such as data size, type, transmission delay analysis and the like.
In practical applications, the calling user may send the session information to the session server in a variety of ways, including:
1. a direct transmission mode;
2. a manner of sending by SIP message (session initiation protocol message);
3. by way of URL (universal resource locator) transmission.
After the calling user selects a proper sending mode, the calling user sends the session information to the session server. The session information includes: session data and session data related information. The session data related information includes information of size, type, transmission delay analysis, title, topic description, and suggested retention time of the data.
A schematic diagram of the calling subscriber sending session information to the session server in different ways is shown in fig. 4.

The user can also set data reception settings and data transmission settings in the session server.
For example, the called user may perform data receiving setting in advance, and set the content and the mode of receiving data in advance, whether to receive the data directly or through other modes. Then, the data receiving setting is sent to a session server, the session server stores the received data receiving setting and sends a data receiving setting response to the called user.
The calling user can also set data transmission in advance, the data transmission setting is transferred to the session server, and the session server stores the data transmission setting and sends a data transmission setting response to the calling user.
Fig. 5 is a schematic diagram illustrating the data receiving setting sent by the called user to the session server.
Then, the session server processes the received session information according to the set data processing strategy, the user data sending setting and the user data receiving setting.
And when the user sending the session information has data sending setting, the session server extracts the session data related information or the session data related information and part of the session data or the part of the session data from the received session information as a session information sample according to the data sending setting. Then, the session server judges whether the user receiving the session information has data receiving setting, if so, the session server sends the session information sampling or session information or prompt information to one or more receiving users according to the data receiving setting; otherwise, the session server sends the session information sample to one or more receiving users.
When the user sending the session information has no data sending setting, if the user receiving the session information has data receiving setting, the session server extracts the session data related information or the session data related information and part of the session data or the part of the session data from the received session information as session information samples according to the data receiving setting, and sends the session information samples or the session information or prompt information to one or more receiving users; otherwise, the session server sends the session information or prompt information to one or more receiving users.
In the above processing procedure, the session server may further change the received session data, generate new session data related information according to the changed session data, and extract the session data related information or the session data related information and part of the session data or the part of the session data from the changed session information as a session information sample. The session server changing the session data comprises: and performing coding, decoding and converting, rate adjusting, format converting and the like on the session data.
The session server may send different prompt messages and different session information samples to different called users or adopt different processing methods, such as sending sample information 1 to user a, sending sample information 2 to user b, and adopting a mode of directly sending session information to user c.
When a plurality of session servers exist, the session server for sending the session information sample or the session information or the prompt information to the called user and the session server for receiving the session information may be the same or different session servers. That is, the session server connected to the calling subscriber needs to transfer the received session data and related information to each intermediate session server. The above-described data transfer process when a plurality of session servers exist is shown in fig. 6.
And 3-3, after receiving the session information sampling or prompting information sent by the session server, the called user performs corresponding processing according to the actual situation and returns an indication message to the session server.
After receiving the above-mentioned session information sampling or prompt information sent by the session server, the called user carries out corresponding processing according to the conditions of own data receiving setting, receiving data bandwidth and the like.
For example, after receiving the session information sampling or the prompt message, the receiving user sends an indication message to the session server to notify the session server to send the received session information to the receiving user;
or,
after receiving the session information sampling or prompting information received by the user, sending an indication message to a session server, and informing the session server to cache the received session information for a set time and then send the session information to the receiving user;
or,
after receiving the session information sampling or prompting information received by the user, sending an indicating message to a session server, and informing the session server to discard the received session information;
or,
after receiving the information session information sampling or prompting information received by the user, sending an indication message to a session server, and informing the session server to send part of contents in the received session information to the receiving user;
or,
and the session server does not receive the indication information of the receiving user, and processes the received session information according to the rule. For example, the session server may sample the session information or resend the prompt information to the receiving user; or, the session server continues to wait for the response of the receiving user; or, the session server discards the received session information.
The session server may further store the received session information according to the set data processing policy, and delete the stored session information after a set time is exceeded or the session is ended.
