Description

Method and system for reducing heartbeat message

The present invention relates to the field of mobile communications, and in particular, to a method and system for reducing heartbeat messages of various applications. Background technique

Receiving and sending data in the network is done using sockets (SOCKET) in WINDOWS. However, if the socket is disconnected, there is a problem with sending and receiving data. To determine if a socket is still available, you need to create a heartbeat mechanism in your system. The so-called "heartbeat" means that the client periodically sends a custom structure (heartbeat message or heartbeat packet or heartbeat frame) to the server, so that the server knows that the client is online, thus ensuring the validity of the long connection between the client and the server.

In a variety of applications, especially applications that use client-server architectures, such as instant messaging, remote data collection, remote management, and some peer-to-peer (P2P, Peer-to-Peer) applications, have a large number of heartbeat messages. In order to make the server aware of the activation status of the terminal application, or to make the terminal and the terminal understand each other's activation status.

The heartbeat message of the instant messaging tool imposes a great burden on the network, especially the mobile communication network. Taking QQ as an example, the client of the QQ application can periodically send the heartbeat message to the application server to achieve the long-term occupation of the external network IP address, and the server can sense the online state of the client through the heartbeat message reported by the terminal. However, due to the large number of QQ user groups, the number of heartbeat messages is also larger. The heartbeat message is for the Global System of Mobile Communication (GSM) network and the third generation mobile communication technology (3G, 3rd-generation). / Long Term Evolution (LTE) network has a great impact, mainly in: On the GSM network, for the signaling plane, QQ and other instant messaging services cause public control The channel (CCCH, Common Control Channel) is overloaded, and causes the CS (Clock Service) paging congestion, which affects the user's basic voice experience. According to statistics, QQ's control channel consumption is 5 to 10 times that of other services such as web browsing and downloading. As a result, CCCH load in some areas exceeds the red threshold or the yellow threshold, which directly causes a low paging success rate and affects the voice user experience. For the business side, part of the always-on-line service packet data channel (PDCH, Packet Data CHannel) resource utilization efficiency is low, resulting in resource consumption and income imbalance.

From the statistics of 3G/LTE networks of foreign operators, always-on applications, especially smart applications on smart terminals, have also had a serious impact on 3G/LTE networks. For the signaling plane, the always-on-line service frequently sends a "heartbeat message", which causes the status of the user's radio resource control (RRC) protocol to change frequently. The core network and the radio network controller (RNC) The inter-Iu interface, the S1 interface user status between the base station and the core network are constantly changing, the paging and service request signaling is increased, and the radio access bear (RAB, Radio Access Bear) signaling is proliferating. According to statistics, for every byte of data sent by a user, an always-on application will generate more than 10 times the amount of signaling for normal services.

Excessive heartbeat messages, the impact on mobile communication networks has seriously affected the normal operation of the network, and affected the normal use of other users, causing a great burden on operators, if not resolved, with QQ The further spread of instant messaging tools and the penetration of the general population, mobile communication networks will eventually be overwhelmed. Summary of the invention

FIG. 7 is a schematic structural diagram of a system for reducing heartbeat messages according to Embodiment 7 of the present invention. detailed description

The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a method for reducing a heartbeat message according to Embodiment 1 of the present invention. As shown in FIG. 1, the method includes: Step S101: After receiving the login request of the UE application module, the application server sends a request for detecting the online status of the PS domain of the UE to the heartbeat proxy server.

The UE application module sends a login request to the application server. After the application server authenticates the login request, the application server sends a request to the heartbeat proxy server to detect the online status of the PS domain of the UE, where the request carries the ID of the UE.

Step S102: After receiving the request for detecting the online status of the PS domain of the UE, the heartbeat proxy server detects the online state of the PS domain of the UE through the wireless communication network.

Detecting the online status of the PS domain of the UE through the wireless communication network can be implemented in various ways:

1. The heartbeat proxy server periodically sends a request to the wireless communication network to query the PS domain online status of the UE.

The application server sends a request for detecting the online status of the PS domain of the UE to the heartbeat proxy server, where the request carries the ID of the UE. The ID of the UE includes but is not limited to a mobile phone number or an IP address.

If the ID of the UE is a mobile number, ie, Mobile Subscriber International ISDN/PSTN Number, the heartbeat proxy server periodically sends a request for querying the PS domain online status of the UE to the HSS/HLR of the wireless communication network. The request carries the ID of the UE. After receiving the request for querying the PS domain online status of the UE, the HSS/HLR queries the PS domain online status information of the UE according to the ID of the UE and returns it to the heartbeat proxy server.

If the ID of the UE is an IP address, the heartbeat proxy server periodically sends a request for querying the online status of the PS domain of the UE to the PDN/GGSN of the wireless communication network, where the request carries the IP address of the UE. After receiving the request for querying the PS domain online status of the UE, the HSS/HLR queries the PS domain online status information of the UE according to the IP address and returns it to the heartbeat proxy server.

2. The heartbeat proxy server sends a request to the HSS/HLR to register the UE. The heartbeat proxy server sends a request for registering the UE to the HSS/HLR, where the request carries the ID of the UE. After receiving the request of the registered UE, the HSS/HLR detects the PS domain of the UE in real time according to the ID of the UE. status information. When detecting that the PS domain online status of the UE is offline, the HSS/HLR notifies the heartbeat proxy server that the UE has gone offline.

Step S103: When it is detected that the online state of the PS domain of the UE is offline, the heartbeat proxy server notifies the application server that the UE application module has gone offline.

After receiving the PS domain online status of the UE returned by the wireless communication network, the heartbeat proxy server notifies the application server that the UE application module has gone offline when the online status of the PS domain of the UE is offline; the PS of the UE When the domain online status is online, the heartbeat proxy server sends a heartbeat message to the application server to notify the application server that the UE is online or the heartbeat proxy server does not send a heartbeat message to the application server but the application server By default the UE is online.

FIG. 2 is a flowchart of a method for reducing a heartbeat message according to Embodiment 2 of the present invention. In this embodiment, an instant communication tool QQ is taken as an example, a QQ client is an application module on a UE, and a QQ server is an application server. As shown in FIG. 2, the method includes:

Step S201: The QQ client on the UE initiates a login request to the QQ server.

After the user enters the QQ number and password in the QQ client, the login button is clicked, and the QQ client on the UE sends a login request to the QQ server.

Step S202, the QQ server acquires the ID of the UE.

After receiving the request from the client, the QQ server performs normal authentication on the user of the QQ client and obtains the ID of the UE. The ID of the UE may be the mobile phone number or IP address of the user. For a UE whose QQ user identity and mobile phone number are bound and the QQ client logs in with the mobile phone, the QQ server can directly obtain the mobile phone number of the user. For users whose QQ user identity and mobile phone number are not bound, the QQ server cannot know the mobile phone number of the user, but can obtain the IP address. Step S203, notifying the QQ client that the heartbeat message is not required to be sent to the QQ server.

The QQ server notifies the QQ client that the heartbeat message is not needed, thereby making the UE

The QQ client no longer sends heartbeat messages to the QQ server.

Step S204: Send related information of the UE to the heartbeat proxy server.

The QQ server sends the related information of the UE to the heartbeat proxy server, including but not limited to the ID of the UE.

Step S205: Add a UE to the UE information maintenance table.

After receiving the UE information sent by the QQ server, the heartbeat proxy server saves the UE information to the UE information maintenance table. The UE information maintenance table includes the user's mobile phone number, IP address, online status, and the like.

Step S206: A request for acquiring the online status of the PS domain of the UE is periodically sent.

The heartbeat proxy server periodically sends a request for obtaining the PS domain online state information of the UE to the HSS/HLR of the wireless communication network, where the request carries the ID of the UE.

Step S207: The HSS/HLR acquires the PS domain online state information of the UE, and indicates the UE

The IP address is not released.

After receiving the request of the heartbeat proxy server to obtain the online state of the PS domain of the UE, the HSS/HLR queries the UE's PS domain online state information according to the UE's ID, that is, the user's MSISDN number or IP address. At the same time, the HSS/HLR instructs the PDN or GGSN to reserve the IP to the UE even if the UE is inactive for a long time. The HSS/HLR querying the PS domain online status of the UE is a prior art and will not be described here.

The heartbeat proxy server can be interconnected with multiple HSS/HLRs, and the heartbeat proxy server can also support selecting a certain HSS/HLR for query according to the ID of the UE. Specifically, the correspondence between the ID of the UE and the HSS/HLR may be pre-stored, or the first query may sequentially query each HSS/HLR, and then record the HSS/HLR where the UE is located, and subsequent queries are directly processed according to the result of the recording. Query the HSS/HLR. The heartbeat proxy server can query the PS domain online status information of multiple UEs in batches. Because there are many users of QQ and the probability of logging in to the QQ server at the same time, the QQ server can also send related information of multiple UEs to the heartbeat proxy server in batches. After receiving the related information of multiple UEs, the heartbeat proxy server also batches The related information of multiple UEs is sent to the HSS/HLR and requests to acquire the PS domain online status of multiple UEs. After receiving the request, the HSS/HLR acquires the PS domain online status of each UE according to the ID of each UE carried in the request.

Step S208, returning online status information of the PS domain of the UE.

The HSS/HLR sends the queried UE's PS domain online status and the IP address reserved by the PDN/GGSN for the UE to the heartbeat proxy server. After receiving the information returned by the HSS/HLR, the heartbeat proxy server updates the information of the corresponding UE in the UE information maintenance table according to the returned information. Specifically, the online status and the IP address of the corresponding UE in the UE information maintenance table are updated according to the PS domain online status of the UE and the IP address of the UE in the returned information. After the UE information maintenance table is updated, the heartbeat proxy server performs different processing according to the online state information of the PS domain of the UE. If the online state of the PS domain of the UE is online, step S209 is performed; otherwise, step S210 is performed.

Step S209, notifying the QQ server that the UE is online in the PS domain.

When the online status of the PS domain of the UE is online, the heartbeat proxy server notifies the QQ server that the UE is online in the PS domain, that is, the application module of the UE is online. The heartbeat proxy server notifies the QQ server in two ways. One is that the QQ client on the simulated UE sends a heartbeat message to the QQ server, and the other is that no message is sent, but the default UE is online in the PS domain.

Step S210, notifying the QQ server that the UE is offline in the PS domain.

The heartbeat proxy server sends a message to the QQ server to inform the QQ server that the UE is not online in the PS domain. After receiving the message of the heartbeat proxy server, the QQ server identifies the QQ user of the UE as offline.

FIG. 3 is a flowchart of a method for reducing a heartbeat message according to Embodiment 3 of the present invention, such as As shown in FIG. 3, the method includes:

Step S301: An application login on the UE.

An application on the UE initiates a login request to the application server.

Step S302: Acquire an ID of the UE.

After the application server performs normal authentication on the UE, the ID of the UE is obtained. This embodiment is

IP address information.

Step S303: Submit the information of the UE to the heartbeat proxy server.

The application server sends the UE information to the heartbeat proxy server. The information of the UE includes the ID of the UE, that is, the IP address. The application server sends the UE information to the heartbeat proxy server whether it needs to retain the identity of the IP.

Step S304, the heartbeat proxy server saves the UE information.

The heartbeat proxy server adds the received UE information to the UE information maintenance table.

Step S305: A request for querying the online status of the PS domain of the UE is periodically sent.

The heartbeat proxy server periodically sends a request to the PDN or the GGSN to query the online status of the PS domain of the UE, where the request carries the IP address of the UE and whether the identifier of the IP needs to be retained.

Step S306, acquiring IMSI information of the UE according to the IP address.

PDN / GGSN after receiving the query request, the IP address of the IP address query is online, and the corresponding international mobile subscriber identity ¹ J another code (IMSI, International Mobile Subscriberldentification Number) information. And, in the case that the identifier of the IP address that is reserved for the user is the reserved IP, the PDN or the GGSN reserves the IP address, otherwise the IP address is not reserved for the UE.

Step S307, returning the IMSI and online status of the UE.

The PDN/GGSN returns the queried IMSI and the UE's PS domain online status to the heartbeat proxy server.

Step S308, recording the IMSI and the corresponding IP address information, and performing the result of the last query. Contrast to determine if the IMSI is still online.

After receiving the message returned by the PDN/GGSN, the heartbeat proxy server compares the IMSI of the received UE with the IMSI of the UE that was last queried in the UE information maintenance table, and determines whether the IMSI corresponding to the IP address changes. If a change occurs, it can be determined that the UE is offline in the PS domain. The heartbeat proxy server updates the last queried IMSI and IP address of the UE in the UE information maintenance table with the IMSI and IP address information of the received UE.

When the online status of the PS domain of the UE is online, the heartbeat proxy server performs step S309, otherwise, step S310 is performed.

Step S309, notifying the application server that the UE is online in the PS domain.

The heartbeat proxy server notifies the application server that there are two ways for the UE to be online in the PS domain. One is to simulate that the application on the UE sends a heartbeat message to the application server, and the other is to not send any message, but the default UE is online in the PS domain.

Step S310, notifying the application server that the UE is offline in the PS domain.

The heartbeat proxy server sends a message to the application server notifying the application server that the UE is not online in the PS domain. After receiving the message of the heartbeat proxy server, the application server identifies the application of the UE as offline.

In addition to the manner of periodically sending a query request by the heartbeat proxy server to obtain the PS domain status of the UE, the above steps 305 to 308 may be replaced by the following steps to obtain the PS domain online state of the UE: Heartbeat Proxy Server Sending a request to register the UE to the PDN/GGSN. After receiving the registration request, the PDN/GGSN detects the online status of the PS domain of the UE in real time, and notifies the heartbeat proxy server when the IP address of the UE is released or the IMSI corresponding to the IP address changes. The PS domain status of the UE is offline. Otherwise, the heartbeat proxy server defaults the PS domain status of the UE to online. The heartbeat proxy server performs step S309 when the PS domain status of the default UE is online, otherwise step S310 is performed.

4 is a flowchart of a method for reducing a heartbeat message according to Embodiment 4 of the present invention, such as As described in FIG. 4, the method includes the following steps:

Step S401: An application login on the UE.

An application on the UE initiates a login request to the application server.

Step S402, obtaining an ID of the UE.

After the application server normalizes the UE, the ID of the UE is obtained, where the ID of the UE is

UE's mobile number.

Step S403, submit the ID of the UE to the heartbeat proxy server.

The application server submits information such as the ID of the UE to the heartbeat proxy server.

Step S404, the heartbeat proxy server maintains information of the UE.

The heartbeat proxy server adds the received UE information to the UE information maintenance table. Step S405: Send a registration request.

The heartbeat proxy server sends a registration request to the HSS/HLR, where the request carries the UE

ID.

Step S406, detecting the online state of the PS domain of the UE in real time.

After receiving the registration request, the HSS/HLR saves the related information of the UE, and detects the online state of the PS domain of the UE in real time. The HSS/HLR detects the online state of the PS domain of the UE according to the ID of the UE, and when it detects that the online state of the PS domain of the UE is offline, step S408 is performed; otherwise, the HSS/HLR does not send any message to the heartbeat proxy server, the heartbeat proxy server The default UE's PS domain online status is online, and step S407 is performed.

Step S407, notifying the application server that the UE is online in the PS domain.

There are two ways to notify the application server. One is that the application on the simulated UE sends a heartbeat message to the application server, and the other is that no message is sent, but the default UE is online in the PS domain. The application server is now waiting to receive other messages to trigger it to perform additional steps.

Step S408, when it is detected that the online status of the PS domain of the UE is offline, the heartbeat proxy server is notified. When it is detected that the online status of the PS domain of the UE is offline, the heartbeat proxy server UE is notified to have gone offline.

Step S409, updating maintenance information of the UE.

The heartbeat proxy server changes the online status of the UE in the UE information maintenance table to be offline or deletes the information of the UE in the UE information maintenance table.

Step S410, notifying the application server that the UE is offline in the PS domain.

The heartbeat proxy server sends a message to the application server notifying the application server that the UE is not online in the PS domain. After receiving the offline message, the application server identifies the application of the UE as offline.

FIG. 5 is a flowchart of a normal exit of an application on a UE according to Embodiment 5 of the present invention. As shown in FIG. 5, the normal exit process includes the following steps:

Step S501: The application module of the UE sends an exit notification to the application server.

Step S502: The application server sends a UE exit message to the heartbeat proxy server.

After receiving the exit notification sent by the application module of the UE, the application server sends a message of the UE exit to the heartbeat proxy server.

Step S503, deleting the UE from the UE information maintenance table.

After receiving the UE exit message, the heartbeat proxy server deletes the information of the UE from the UE information maintenance table.

If the PS domain online status of the UE is obtained from the wireless communication network by sending a registration request to the HSS/HLR or the PDN/GGSN, the heartbeat proxy server also needs to send a notification to the HSS/HLR or the PDN/GGSN to delete the UE. After receiving the deletion notification, the HSS/HLR or the PDN/GGSN deletes the related information of the saved UE.

The application module on the UE in the foregoing fifth embodiment is normally exited, but sometimes the application on the UE is abnormally terminated. In the case of abnormal termination, the application module on the UE does not send a message to the application server to log out. At this time, if the user restarts the application, follow the above implementation. In the example, the normal login process can be processed, but if the user does not restart the application, the application server will not send the user's exit request to the heartbeat proxy server, and the heartbeat proxy server will continue to monitor the wireless communication network, if the UE still maintains The PS domain is online, then the application server will also consider the UE to remain online. Therefore, the abnormal termination problem of the application on the UE must be solved.

6 is a process flow when an application on a UE that is provided by the implementation of the sixth embodiment of the present invention is abnormally interrupted and cannot normally issue an exit login message. As shown in FIG. 6, the process includes:

Step S601: The application server sends a data packet to the abnormally exited UE.

The application server or other UE sends a data packet to the abnormally exited UE. The data packet may be forwarded by other UEs through the application server. For example, the QQ user on other UEs sends a message to the QQ application of the UE, or the application server itself sends a message to the QQ application of the UE. Currently, for this application packet, an ACK confirmation response is automatically requested.

Step S602: The PDN/GGSN detects that the transmission fails.

When the data packet is sent to the PDN or GGSN, the PDN or GGSN will detect the transmission failure because the application of the UE has been abnormally closed.

Step S603, returning a failure message.

After detecting the failure of the PDN or GGSN, the PDN or GGSN returns a failure message to the application server. After receiving the message that the transmission fails, the application server knows that the application on the UE has abnormality.

Steps S601 to S603 are repeatedly performed multiple times. After multiple attempts, if the application server still receives the message that the transmission fails, the UE is considered to have exited abnormally.

Step S604, sending a message that the UE has gone offline to the heartbeat proxy server.

The application server sends a message that the user has gone offline to the heartbeat proxy server.

Step S605: The UE is deleted from the UE information maintenance table.

After receiving the offline message sent by the application server, the heartbeat proxy server deletes the UE from the UE information maintenance table or marks the UE as offline. In the case where the application on the UE is abnormally terminated, there is another extreme case where the application on the UE is neither restarted nor any other UE or application server sends a packet to it for interaction. The consequence of this extreme situation is that the state of the UE is incorrectly displayed and there are no usage problems. If any subsequent packets interact with the application on the UE, then the online status of the application for the UE can still be corrected.

In order to completely avoid such a small probability event, the application server or the heartbeat proxy server may also send a probe message to the UE at a certain frequency, but in this case, there will be some heartbeat information in the future. Considering that this extreme situation is a small probability event, and such a small probability event does not affect the use, the step of transmitting the probe packet by the application server or the heartbeat proxy server can be omitted.

FIG. 7 is a schematic structural diagram of a system for reducing a heartbeat message according to Embodiment 7 of the present invention. As shown in FIG. 7, the system includes: a UE, a wireless communication network, a heartbeat proxy server, and an application server, where the application server may have Multiple units, application modules installed on the UE, and multiple HSS/HLRs and multiple PDN/GGSNs in the wireless communication network. The interface between the heartbeat proxy server and the application server is interface 1, the interface of the heartbeat proxy server and the HSS/HLR is interface 2, and the interface of the heartbeat proxy server and the PDN/GGSN is interface 3.

The UE is a user terminal on which various application modules that need to send heartbeat messages to the application server are run.

The application module installed on the UE is used to send a login message to the application server. The application module mainly refers to various applications that require heartbeat messages, including but not limited to instant messaging services such as QQ.

MSN, etc., remote data collection or control, such as Internet of Things applications.

The application server is configured to send, to the heartbeat proxy server, a request for detecting the online status of the PS domain of the UE after receiving the login request of the UE application module.

a heartbeat proxy server, configured to: after receiving a request for detecting a PS domain online state of the UE, detecting an online state of the PS domain of the UE by using a wireless communication network, and detecting the When the PS domain online status of the UE is offline, the application server is notified that the UE application module has gone offline; when detecting that the PS domain online status of the UE is online, sending a heartbeat message to the application server to notify the The UE application module of the application server is online. Of course, the heartbeat proxy server may not send any message to the application server, but the application server defaults that the UE application module is online. The step of detecting, by the heartbeat proxy server, the online state of the PS domain of the UE through the wireless communication network, specifically, the heartbeat proxy server periodically sends an inquiry to the HSS/HLR or the PDN/GGSN of the wireless communication network to query the online state of the PS domain of the UE. The request, HSS/HLR or PDN/GGSN returns the queried online status result to the heartbeat proxy server. Or the heartbeat proxy server sends a request for registering the UE to the HSS/HLR. The HSS/HLR detects the online status of the PS domain of the UE in real time and notifies the heartbeat proxy server when it detects that the online state of the PS domain of the UE is offline.

A wireless communication network is configured to detect an online state of a PS domain of the UE. The wireless communication network includes an HSS/HLR, a PDN/GGSN. The HSS/HLR queries the PS domain of the UE according to the ID of the UE carried in the request for querying the online state of the PS domain of the UE after receiving the request of the heartbeat proxy server to periodically query the PS domain online state of the UE. The online status information is returned to the heartbeat proxy server; after receiving the request for registering the UE sent by the heartbeat proxy server, the HSS/HLR detects the UE in real time according to the ID of the UE carried in the request of the registered UE. The PS domain is in the online state information, and when it is detected that the online state of the PS domain of the UE is offline, the heartbeat proxy server is notified that the UE has gone offline. After receiving the request of the heartbeat proxy server to periodically query the PS domain online state of the UE, the PDN/GGSN queries the PS domain of the UE according to the IP address of the UE carried in the request for querying the PS domain online state of the UE. Status information is returned to the heartbeat proxy server.

In summary, the present invention can obtain the online state of the user through the application of the heartbeat proxy server, and does not require the application on the UE to send the heartbeat message, which not only can greatly save network resources, but also can reduce the power consumption of the terminal, simplifying the operation. The processing complexity of the application's terminal side and service. Although the invention has been described in detail above, the invention is not limited thereto, and various modifications may be made by those skilled in the art in accordance with the principles of the invention. Therefore, modifications made in accordance with the principles of the invention should be construed as falling within the scope of the invention.
