Description

Data packet transmission control method and device in message service

technical field

The invention relates to communication technology, in particular to a transmission control method and equipment for data packets in message services.

Background technique

In a mobile communication network, in order to save wireless resources and reduce terminal power consumption, when the terminal does not perform signaling interaction or user plane data transmission with the network for a period of time (such as 6 to 8 seconds), the network can release The signaling connection between terminals and the radio bearer of the user plane are called terminals in idle state (Idle State) or sleep state (Sleep State). When the terminal needs to send or receive user plane data, the terminal will first restore the signaling connection with the network, restore the user plane radio bearer through signaling, and then send or receive user plane data through the user plane radio bearer. At this time, the terminal is said to be connected. State (Connected State). After the service ends, if there is no signaling interaction or user plane data transmission for a period of time, the network will turn the terminal to the idle state or sleep state again.

Currently, interactive instant messaging services commonly used by terminals, such as QQ services and MSN services, have the characteristics of small data packets when the services occur, and frequent message interactions between the communication parties. In this type of service, one party to the communication sends a message, and the receiving end of the communication responds after receiving the message. Due to the speed limit of people inputting messages on the terminal, after editing the message on the terminal, both the sender and the receiver may have switched to the idle state, so the sender of each message is sending the message, and the receiver is in the When receiving messages, it may be necessary to switch from the idle state to the connected state, resulting in a surge in signaling load.

Contents of the invention

The embodiments of the present invention provide a method and device for controlling the transmission of data packets in a message service, which prevents terminals from frequently switching between an idle state and a connected state in the message service, thereby achieving the purpose of reducing signaling load.

An embodiment of the present invention provides a transmission control method of a data packet in a message service, including:

Receive the data packet sent by the terminal;

Comparing the interval between the time when the data packet is received and the latest forwarding time of the data packet to the opposite end corresponding to the terminal, if the interval is less than a set threshold, buffering the data packet until the interval After the threshold is reached, the buffered data packet is sent to the opposite end.

An embodiment of the present invention provides a transmission control device for data packets in a message service, including:

The receiving module is used to receive the data packet sent by the terminal;

A cache module, configured to compare the interval between the time when the receiving module receives the data packet and the latest forwarding time of the data packet to the opposite end corresponding to the terminal, if the interval is less than a set threshold, then cache the data packets;

A sending module, configured to send the cached data packet to the peer after the cache module caches the data packet until the interval reaches the threshold.

In the present invention, by buffering data packets until the time interval reaches the threshold, it is not simply reducing the interaction frequency between the two ends of the communication to reduce the signaling overhead, but using the "one to one" communication between the two parties in the interactive message system The characteristic is that after one party sends a message, it usually waits for the other party's reply message before sending a new message.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Fig. 1 is a schematic flow chart of the method of the first embodiment of the present invention, including:

Step 11: receiving the data packet sent by the terminal;

Wherein, in the embodiment of the present invention, the messages communicated by the communication parties in the message service are collectively referred to as data packets, including texts, pictures, and the like.

Step 12: Comparing the interval between receiving the data packet and the latest data packet forwarding time of the opposite end corresponding to the terminal, if the interval is less than the set threshold, buffering the data packet until the After the interval reaches the threshold, the cached data packet is sent to the peer.

In addition, if the interval is greater than or equal to the threshold, the data packet is directly forwarded to the peer; or, if the forwarding time is not recorded, the data packet is directly forwarded to the peer.

In the embodiment of the present invention, the following methods can be used to record the forwarding time of the last data packet at the opposite end:

One is the time when the latest data packet is received from the peer end and sent to the local end before the caching mechanism is executed; the other is the time after the caching mechanism is executed, which refers to caching data packets until the interval reaches the threshold (that is, executing the After the caching mechanism) is forwarded to the local end.

In addition, the executor in this embodiment may be an application server of a non-communication network device, such as an application server provided by an application service provider, or a communication network device such as a data gateway, a service gateway, a base station, a base station controller, and the like.

In this embodiment, data packets are cached until the time interval between messages exchanged between the two ends reaches the threshold. Instead of reducing the signaling overhead simply and bluntly by reducing the frequency of interaction between the two ends of the communication, it utilizes the "one-time communication" between the two parties in the interactive message system. The characteristic of “coming and going” means that after one party sends a message, it usually waits for the other party’s reply message before sending a new message. By appropriately prolonging the time for the reply message to the extent that the user can tolerate, the two parties in the communication are waiting for the other party. In the process of replying, the "hotness" is unconsciously reduced, or even the conversation is ended early, and the frequency of messages is reduced without significantly affecting user satisfaction, thereby reducing signaling overhead.

FIG. 2 is a schematic flowchart of a method according to a second embodiment of the present invention. In this embodiment, the application server of a message application controls the time interval for sending messages as an example. Referring to Fig. 2, the present embodiment includes:

Step 21: the application server receives the data packet sent by the terminal.

For example, when the terminal sends the data packet, it sends the data packet to the application server through the packet data network of the terminal, so as to send the data packet to the opposite end of the terminal through the application server.

Step 22: The application server compares the interval between the time when the data packet is received and the last forwarding time of the data packet to the peer end corresponding to the terminal.

Step 23: The application server judges whether the interval is smaller than the set threshold, if yes, execute step 24, otherwise execute step 25.

Step 24: The application server caches the data packets until the interval reaches a set threshold, and then enters Step 25.

Step 25: The application server forwards the received data packet to the peer end of the terminal, and records the current time as the latest data packet forwarding time of the terminal.

Before the cached data packets are forwarded, the application server may receive new data packets from the local end or the opposite end. At this time, the application server can cache and discard the new data packets according to different configuration policies, or when the data packets from the same end If the number reaches the set threshold, it will be forwarded immediately and other processing methods.

In addition to the application server, other network elements on the communication path between the communication parties, such as data gateways, service gateways, base stations, and base station controllers in the mobile communication network, can also compare with Whether the time interval between the last forwarding time of the peer end data packet is lower than a specific threshold determines whether the message needs to be cached. The difference is that since the application server handles the peer-to-peer layer of the message session application of the two parties in communication, the application server can easily parse the message from the data stream, while the communication network is at the lower layer of the message session between the two parties in communication, which is the role of a pipeline. The data packets of the application are transparent to the communication network, so the nodes in the communication network may need to apply technologies such as Deep Packet Inspect (DPI) to filter out the data packets of the message application from the data stream.

In addition, the application server can also be used to implement the cache data packet mechanism, and the communication network, such as the network element equipment such as the data gateway in the mobile communication network, implements the monitoring of the cache mechanism. For example, the data gateway equipment starts the timer. When the timer does not expire, If the data packet forwarded by the application server is received, the data packet can be discarded to ensure the smooth execution of the caching mechanism.

The determination of the threshold corresponding to the time interval is a key parameter of the control effect of the present invention. The longer the threshold, the lower the frequency of message interaction between the two parties is allowed, and the lower the load on the network, but the user satisfaction may decrease with time. Conversely, the longer the threshold, the higher the frequency of message interaction between the two parties is allowed, and the higher the load on the network, but the higher the user satisfaction. The threshold should be reasonably set according to the characteristics and user satisfaction, and can be differentiated according to user type, user location, time period, business type, etc. At the same time, it is also possible to reward users who previously sent messages less frequently, such as allowing the user not to be limited by the time interval in a short period of time, or to send more messages controlled by a smaller threshold.

In addition to reducing the frequency of switching between the idle state and the connected state, the embodiment of the present invention will indirectly affect the user's communication behavior: under the premise of less impact on the user experience, the time interval of the user's message interaction is relatively prolonged, and the user's message interaction is subtle This kind of slight change may affect the user's communication habits, and the two sides of the interactive message may minimize unnecessary message interaction, which may shorten the time of interactive message communication. Therefore, from the perspective of user psychology, the technical solution of the present invention can potentially change people's communication habits in interactive message services, thereby reducing the huge impact of real-time communication services on mobile communication networks.

The receiving module 31 is used to receive the data packet sent by the terminal; the cache module 32 is used to compare the time between the time when the receiving module 31 receives the data packet and the forwarding time of the latest data packet of the opposite end corresponding to the terminal interval, if the interval is less than the set threshold, then buffer the data packet; the sending module 33 is used to cache the data packet until the interval reaches the threshold after the cache module 32 buffers the buffered The data packet is sent to the peer.

The sending module 33 of this embodiment can also be used to forward the data packet directly to the peer if the interval is greater than or equal to the threshold; or, if the forwarding time is not recorded, directly forward the data packet to the peer.

It may also include: a recording module, configured to record the time when the latest data packet of the peer is received and sent to the terminal is recorded as the Forwarding time; or, if the caching mechanism has been executed when the last data packet of the opposite end is received, the time when the latest data packet of the opposite end is received and the caching mechanism is executed is recorded as The forwarding time.

It may also include: a processing module, configured to cache and discard the new data packet or perform processing when the number of data packets from the same end reaches a preset threshold if a new data packet is received when the data packet is cached. Forward processing.

The device in this embodiment may be located at an application server of a non-communication network device, and/or at a data gateway, service gateway, base station controller or base station of a communication network device.

If the device is located at a communication network device, the cache module is further configured to perform DPI on the data packet, and if the result of the DPI is that the service corresponding to the data packet is a message service, cache the data packet.

In this embodiment, data packets are cached until the time interval between messages exchanged between the two ends reaches the threshold. Instead of reducing the signaling overhead simply and bluntly by reducing the frequency of interaction between the two ends of the communication, it utilizes the "one-time communication" between the two parties in the interactive message system. The characteristic of “coming and going” means that after one party sends a message, it usually waits for the other party’s reply message before sending a new message. By appropriately prolonging the time for the reply message to the extent that the user can tolerate, the two parties in the communication are waiting for the other party. In the process of replying, the "hotness" is unconsciously reduced, or even the conversation is ended early, and the frequency of messages is reduced without significantly affecting user satisfaction, thereby reducing signaling overhead.
