Description
Technical Field
The present disclosure relates to a nomadic terminal, and in particular, to a method and a system for detecting a heartbeat cycle of the nomadic terminal, the nomadic terminal and an application server.
Background
In a mobile communication network, a terminal accesses a mobile network through an air interface and finally accesses an application server. A firewall-like device is typically present between the mobile communication network and the network where the user application is located, as shown in fig. 1. In some cases, there may be multiple firewalls, with different authorities responsible for configuration and management. A Protocol is developed between a general terminal and an application based on UDP (user datagram Protocol), and as an Idle Timer exists in UDP session connection by a firewall, if there is no data transmission between the terminal and the application within the period of the Idle Timer length, the firewall closes the session connection between the terminal and the application stored in the firewall, that is, deletes session information in the firewall, thereby causing interruption of bidirectional UDP message transmission between the application and the terminal.
The traditional solution is to enable a heartbeat mechanism between the terminal and the application, that is, the terminal sends a heartbeat message to the application at a fixed period, so that the session connection information in the firewall can be refreshed before the Idle Timer expires, so as to continue to maintain the session connection information in the firewall, and finally, the maintenance of the bidirectional communication between the application and the terminal is realized.
There are a large number of applications where nomadic terminals, such as hydrological monitoring terminals and sewage drain monitoring terminals, access a mobile communication network, either fixedly placed in one place or used in a nomadic way. In a general heartbeat period setting method, no matter the heartbeat period setting is manually set one by one at a terminal or a network is issued when the terminal logs in for the first time, a certain heartbeat period value is directly specified by the experience of engineering personnel. Terminals of the same type may be deployed in multiple regions, and for convenience, the minimum value of the individually applicable heartbeat cycle values is often adopted, which is the most secure scheme but not the better scheme. This facilitates engineering implementation and management, but in some areas results in sending heartbeats in a cycle much lower than the locally applicable value, unnecessarily consuming more air interface resources and increasing the processing workload of the terminal.

Detailed Description
The present disclosure will be described below with reference to the accompanying drawings. It is to be noted that the following description is merely illustrative and exemplary in nature and is in no way intended to limit the disclosure, its application, or uses. Unless specifically stated otherwise, the relative arrangement of components and steps and numerical expressions and values set forth in the embodiments do not limit the scope of the present disclosure. Additionally, techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail but are intended to be part of the specification where appropriate.
The embodiments described below in the present disclosure are directed to a nomadic terminal using a UDP protocol in a mobile communication network environment, and a relatively accurate heartbeat period associated with a position of the nomadic terminal can be obtained through an automatic detection manner of sending a heartbeat message and receiving a heartbeat message response.
Fig. 2 is a flowchart illustrating a method for detecting a heartbeat cycle of a nomadic terminal according to an embodiment of the present disclosure.
As shown in fig. 2, this embodiment may include the steps of:
s202, the nomadic terminal carries current position information and a heartbeat cycle when logging in an application server;
s204, receiving a heartbeat cycle negotiation message initiated by the application server, wherein the message carries an initial heartbeat cycle of the network side, and the initial heartbeat cycle of the network side is taken as a current heartbeat cycle, for example, the initial heartbeat cycle of the network side can be 30 seconds;
s206, sending a heartbeat message to an application server based on the current heartbeat cycle obtained from the heartbeat cycle negotiation message, wherein the heartbeat message carries the currently used heartbeat cycle;
s208, after receiving the corresponding heartbeat message response from the application server, sending the next heartbeat message by taking the gradually increased heartbeat period carried in the heartbeat message response as the current heartbeat period until the heartbeat message response from the application server cannot be received, and automatically detecting the maximum available heartbeat period which can be supported at the current position of the nomadic terminal by utilizing the mode;
the current heartbeat cycle can be gradually increased in a mode of the same step length, for example, the step length can be 10 seconds, and because the value of the heartbeat cycle is closer to the optimal value in the process of increasing the heartbeat cycle, the current heartbeat cycle can also be gradually increased in a mode of gradually reducing the step length, so that the convergence rate of the optimized heartbeat cycle can be increased, and the negotiated heartbeat cycle can be closer to the better heartbeat cycle;
and S210, taking the heartbeat cycle carried in the heartbeat message which is sent by the nomadic terminal for the last time and successfully receives the corresponding response as the negotiated heartbeat cycle.
The embodiment enables the nomadic terminal to start sending the heartbeat message according to the initial value of the heartbeat period of the network side, gradually increases the length of the heartbeat period after receiving the response of the heartbeat message, and tries to carry out heartbeat interaction with the application server until the connection between the nomadic terminal and the application server is stopped. At this time, the heartbeat cycle carried in the heartbeat message which is sent by the nomadic terminal for the last time and successfully receives the corresponding response is taken as the negotiated heartbeat cycle. The optimized heartbeat cycle detected according to different access positions of the nomadic terminal can obviously reduce the situations of network flow increase, network load increase, terminal power consumption increase and the like caused by sending heartbeat messages at improper and fast frequency.
After step S210, when the nomadic terminal logs in the application server again, if the application server does not record the heartbeat cycle corresponding to the reported current location information of the nomadic terminal, the reported heartbeat cycle is correlated with the reported current location information and recorded in the application server, so that when logging in another nomadic terminal having the same location as the nomadic terminal, it is not necessary to perform repeated heartbeat cycle negotiation on the same location; if the application server records the heartbeat cycle corresponding to the reported current position information of the nomadic terminal, comparing whether the reported heartbeat cycle is the same as the recorded heartbeat cycle, if the two are different, sending the heartbeat cycle corresponding to the reported current position information recorded on the application server to the nomadic terminal to prevent the heartbeat cycle at the side of the nomadic terminal from being mistakenly changed, if the two are the same, the application server does not need to contain the heartbeat cycle in response.
Fig. 3 is a flowchart illustrating a method for detecting a heartbeat cycle of a nomadic terminal according to another embodiment of the present disclosure.
As shown in fig. 3, this embodiment may include the steps of:
s302, the nomadic terminal carries the current position information and the heartbeat cycle of the nomadic terminal when logging in the application server.
And S304, the application server judges whether the nomadic terminal logs in for the first time according to the heartbeat cycle reported by the nomadic terminal, wherein the first login has two conditions, one is the first login when the nomadic terminal is used for the first time, and the other is the first login executed when the nomadic terminal detects that the position of the nomadic terminal is changed. If the login is the first login, the heartbeat cycle negotiation is performed with the nomadic terminal by sending a heartbeat cycle negotiation message, and a specific negotiation process can refer to steps S204 to S210 in the embodiment shown in fig. 2;
the nomadic terminal typically compares the locally recorded location information with the location information of the current cell broadcast from the mobile network air interface to find out whether it is located at a new location and needs to perform the first login again.
The application server may determine whether the nomadic terminal is logged in for the first time according to an identifier of a heartbeat cycle field during logging in, for example, when the identifier is 0 or a negative number, it may be determined that the nomadic terminal is logged in for the first time, and when the identifier in the field is a positive integer greater than 0, it is denied that the nomadic terminal is not logged in for the first time.
As shown in fig. 4, the nomadic terminal logs in for the first time, carrying the current location information and the heartbeat cycle (set to 0). The application server finds that the current heartbeat cycle of the terminal is 0, can recognize that the nomadic terminal is logged in for the first time, and then issues the initial heartbeat cycle X of the network side1And informing the nomadic terminal to start a heartbeat cycle negotiation process.
After receiving the response of the application server, the nomadic terminal uses the heartbeat cycle X1Sending the next heartbeat message, and sending the next heartbeat period value X in the response after the application server receives the next heartbeat message2＝X1+Y。
After receiving the response, the nomadic terminal uses the heartbeat cycle X2Sending the next heartbeat message, and sending the next heartbeat period value X in the response after the application server receives the next heartbeat message3＝X2+Y。
If the nomadic terminal does not receive the response of the application server after finding that the nomadic terminal sends the heartbeat message, the nomadic terminal sets the heartbeat period to be XN-1. (assume that the heartbeat cycle currently used by the nomadic terminal is XN）。
The nomadic terminal informs the application server of adopting X between the nomadic terminal and the application server when logging in next timeN-1As the heartbeat cycle.
The heart-beat period negotiation process is characterized in that an optimized heart-beat period is sought by adopting an automatic heart-beat detection mechanism, and a mode of increasing by taking a fixed length as a unit every time can be adopted, and a mode of increasing the amplitude to be longer can also be adopted.
For example, the fixed step algorithm:
X,X+Y,X+2Y,X+3Y,X+4Y,X+5Y,…
variable step size algorithm:
X,X+Y,X+Y+Y/2,X+Y+Y,X+2Y+Y/3,X+2Y+2Y/3,X+3Y,
X+3Y+Y/4,...。
in this embodiment, by obtaining a better heartbeat cycle through the above procedure, network traffic between the application server and the nomadic terminal can be reduced, and power consumption of the terminal can be reduced.
Fig. 5 is a flowchart illustrating a method for detecting a heartbeat cycle of a nomadic terminal according to another embodiment of the present disclosure.
As shown in fig. 5, this embodiment may include the steps of:
s502, the application server judges whether the nomadic terminal logs in for the first time according to the heartbeat cycle reported by the nomadic terminal;
s504, if the nomadic terminal logs in for the first time, whether a heartbeat cycle corresponding to the reported current position information of the nomadic terminal is recorded on the application server or not is judged;
s506, if not, performing a heartbeat cycle negotiation with the nomadic terminal by sending a heartbeat cycle negotiation message, where the specific negotiation process may refer to steps S204 to S210 in the embodiment shown in fig. 2, otherwise, directly sending the recorded heartbeat cycle corresponding to the reported current location information of the nomadic terminal to the nomadic terminal;
in this embodiment, even if the nomadic terminal logs in for the first time, if the application server records the heartbeat cycle corresponding to the reported current location information of the nomadic terminal, the nomadic terminal logging in for the first time does not need to perform new heartbeat cycle negotiation on the current location, so as to save system resources.
In the above embodiment, if the nomadic terminal does not receive the heartbeat message response from the application server when the timeout time F of a single message after the heartbeat message is sent reaches, the nomadic terminal shall immediately retransmit the heartbeat message until the heartbeat message response is received within the timeout time F or the preset maximum retransmission time C is reached, and if the heartbeat message response is not received after the retransmission time C, it is determined that the transmission of the heartbeat message fails. Wherein the timeout F may be set to 5 seconds and the maximum number of retransmissions may be set to 2.
It should be noted that, after the retransmission mechanism is adopted, the influence of the retransmission times and the transmission delay needs to be considered when determining the negotiated heartbeat period. Thus, the value of the negotiated heartbeat period may be updated based on the single message timeout time (i.e., maximum transmission delay) and the number of retransmissions.
For example, after the heartbeat message is not retransmitted to implement negotiation of a heartbeat period, a real heartbeat period between the nomadic terminal and the application server is the negotiated heartbeat period in the embodiment shown in fig. 2, and then the maximum transmission delay of a single message is subtracted, that is, X is the maximum transmission delay of the single messageN-1-F。
Next, a method of correcting the negotiated cardiac cycle will be described in detail with reference to fig. 6a and 6 b.
Fig. 6a is a schematic diagram related to a heartbeat cycle calculation adjustment method in consideration of an extreme condition of a heartbeat packet transmission delay in the embodiment of the present disclosure.
As shown in FIG. 6a, during the negotiation of the heartbeat, the terminal uses X for the i-1 th timei-1The heartbeat period is a heartbeat period, and after retransmitting the heartbeat message for D times, the heartbeat response is successfully received, and finallyEnd on the ith use XiIf the period is equal to the period and the heartbeat response is successfully received after the heartbeat message of the times E is retransmitted, Y isi=Xi- (D +1) × F, the current negotiated heartbeat period recorded by the terminal should be Zi=Max（Yi,Yi-1). When the terminal uses XNWhen the heartbeat message is sent for a period and no response message is received for a plurality of times, the negotiation process is stopped, and the result of the negotiation is that the heartbeat period is ZN-1Instead of the original XN-1. That is, after the terminal logs in the application server later, it should log in every ZN-1- (C +1) × F sending heartbeat message to reserve (C +1) × F time length for possible normal message retransmission, if the application server is in ZN-1If the heartbeat message of the terminal is not received in the period, the connection is considered to be interrupted. In general, the application server issues the heartbeat period value X for the first time in the heartbeat negotiation process1Should satisfy X1>(C+1)×F。
Fig. 6b is a schematic diagram of sending heartbeat messages in the last three times of the terminal based on the method in fig. 6 a.
As shown in fig. 6b, unlike fig. 6a, fig. 6b shows the situation where the heartbeat messages are successfully sent the last two times, i.e., the N-2 nd and N-1 st times. The two corresponding corrected heart beat periods are respectively YN－2And YN－1. Because the terminal does not receive the response sent by the application server through C times of retransmission when the terminal sends the heartbeat message for the Nth time, the connection between the terminal and the application server is stopped, and therefore, the terminal sends Y times of heartbeat messagesN－2And YN－1The maximum value of the parameters is used as the heartbeat period after negotiation and correction, and Y is reported to the application server when the terminal logs in the application server againN－2And YN－1Maximum value of (2).
For a nomadic terminal which logs in an application server for the first time at a certain position, retransmission may occur when the negotiated heartbeat period is determined due to various factors such as unstable link, and the retransmitted heartbeat messages are all lost before reaching a firewall, which affects the accuracy of the heartbeat period corresponding to the position to a certain extent, so that the accuracy of the negotiated heartbeat period is further improved by the statistical method in fig. 7.
Fig. 7 is a flowchart illustrating a method for detecting a heartbeat cycle of a nomadic terminal according to still another embodiment of the present disclosure.
As shown in fig. 7, this embodiment may include the steps of:
s702, the application server determines whether the logged-in nomadic terminals are the first M nomadic terminals logged in at the same location, where whether the locations are the same is determined according to the structure of the mobile communication network, and it can be considered that the locations are the same only if the firewall devices passed by the communication links passed by the nomadic terminals and the application server do not change, for example, the nomadic terminals located in a local city may be the nomadic terminals with the same locations, or even the nomadic terminals located in a province in some cases, the nomadic terminals with the same locations may be the nomadic terminals with the same locations, which depends on the actual deployment situation of the firewall in the network. Using a combination of SID and NID, for example, in a CDMA1X network, one can generally distinguish between "different locations" that meet the above characteristics.
S704, if yes, performing a heartbeat cycle negotiation with the nomadic terminal by sending a heartbeat cycle negotiation message regardless of whether the nomadic terminal logs in for the first time, where the specific negotiation process may refer to steps S204 to S210 in the embodiment shown in fig. 2, otherwise, directly sending the recorded heartbeat cycle corresponding to the reported current location information of the nomadic terminal to the nomadic terminal;
it should be noted that, in step S704, if the negotiation of the heartbeat cycle needs to be performed, it may be further determined whether a certain login is the first login at the location, and if the certain login is the first login, the negotiation may be started according to the initial heartbeat cycle of the network side issued by the application server, and if the certain login is not the first login at the location, on one hand, the negotiation may be started based on the initial heartbeat cycle of the network side, and on the other hand, in order to improve the negotiation speed, the negotiation may also be started based on the maximum heartbeat cycle corresponding to the same location recorded on the application server, so that the negotiation speed may be significantly improved.
S706, after the M nomadic terminals complete heartbeat period negotiation, selecting the maximum value in the M negotiated heartbeat periods to be recorded as a heartbeat period corresponding to the reported same position for subsequent use by other nomadic terminals logging in the same position, or comparing the reported heartbeat period with the heartbeat period recorded in the application server when the M nomadic terminals log in again, and if the M nomadic terminals do not log in again, sending a more accurate heartbeat period value in statistical significance to the nomadic terminals.
The embodiment can minimize the influence on the heartbeat cycle caused by the extreme condition that all heartbeat message retransmissions are lost in the negotiation process of a certain nomadic terminal.
In the above embodiment, when the nomadic terminal is under the CDMA1X Network, the current location information of the nomadic terminal may be a SID (System Identification) or a combination of a SID and a NID (Network Identification), and it should be noted that the combination of the SID and the NID is more accurate than the Identification of the location information by using the SID alone.
The following description will be given taking a terminal in a CDMA1X network as an example.
The CDMA1X terminal may obtain BSID (Base Station Identity code) information, where the BSID is composed of SID, NID, and Base Station ID.
