Embodiment
The disclosure is described below with reference to accompanying drawings.Be noted that following being described in is only explanatory and exemplary in essence, never as any restriction to the disclosure and application or use.Unless stated otherwise, otherwise the parts of setting forth in an embodiment and the positioned opposite of step and numeral expression formula and numerical value do not limit the scope of the present disclosure.In addition, technology well known by persons skilled in the art, method and apparatus may not be discussed in detail, but are intended in appropriate circumstances become a part for specification.
The following embodiment of the disclosure is for the roam terminals that uses udp protocol under mobile communications network environment, and the automatic detection mode of replying with reception heartbeat message by transmission heartbeat message can obtain the heart beat cycle being associated with roam terminals position more accurately.
Fig. 2 is according to the schematic flow sheet of the method for the detection roam terminals heart beat cycle of an embodiment of the present disclosure.
As shown in Figure 2, this embodiment can comprise the following steps:
S202, roam terminals carries current location information and the heart beat cycle of roam terminals while logining application server;
S204, receives the heart beat cycle negotiation message that application server is initiated, and carried the initial heart beat cycle of network side, and using heart beat cycle initial network side as current heart beat cycle, for example, the initial heart beat cycle of network side can be 30 seconds in this message;
S206, the current heart beat cycle based on obtaining in heart beat cycle negotiation message sends heartbeat message to application server, carries the heart beat cycle of current use in heartbeat message;
S208, after receiving and replying from the corresponding heartbeat message of application server, the heart beat cycle increasing gradually carrying in heartbeat message is replied sends heartbeat message next time as current heart beat cycle, reply the available heart beat cycle of maximum that profit in this way can automatic detection can be supported to the current position at roam terminals until do not receive from the heartbeat message of application server;
Wherein, can adopt the mode of identical step-length to increase progressively gradually current heart beat cycle, for example, this step-length can be 10 seconds, and in the process increasing progressively at heart beat cycle, this heart beat cycle value more and more approaches optimal value, therefore also can adopt the mode of dwindling gradually step-length to increase progressively gradually current heart beat cycle, like this, can accelerate to optimize on the one hand the convergence rate of heart beat cycle, also can make on the other hand the more approaching preferably heart beat cycle of heart beat cycle after consulting;
S210, receives the heart beat cycle of the heart beat cycle carrying in the heartbeat message that correspondence replys after consulting using the last roam terminals success sending.
This embodiment makes roam terminals to start to send heartbeat message with the heart beat cycle initial value of network side, after receiving heartbeat message and replying, increase gradually the length of heart beat cycle, attempt that to carry out heartbeat mutual with application server, until be connected termination between roam terminals and application server.Now, the last roam terminals success sending is received to the heart beat cycle of the heart beat cycle carrying in the heartbeat message that correspondence replys after consulting.Heart beat cycle after this optimization detecting according to the difference of roam terminals on-position can significantly reduce the generation due to situations such as the network traffics increase, network load increase and the terminal power consumption increases that cause with inappropriate very fast frequency transmission heartbeat message.
After step S210, in the time that roam terminals is logined application server again, as application server does not record the heart beat cycle corresponding with the current location information of the roam terminals reporting, the heart beat cycle reporting be associated with the current location information reporting and be recorded in application server, while making identical with this roam terminals position other roam terminals logins, consulting without the heart beat cycle that again repetition is carried out in identical position; As application server records the heart beat cycle corresponding with the current location information of the roam terminals reporting, whether the heart beat cycle relatively reporting is identical with the heart beat cycle of record, because the relative roam terminals side of application server stability is high, therefore as both are different, the heart beat cycle corresponding current location information recording on application server with report is sent to roam terminals, changed by mistake with the heart beat cycle that prevents roam terminals side, as identical in both, application server in replying without comprising again heart beat cycle.
Fig. 3 is according to the schematic flow sheet of the method for the detection roam terminals heart beat cycle of another embodiment of the present disclosure.
As shown in Figure 3, this embodiment can comprise the following steps:
S302, roam terminals carries current location information and the heart beat cycle of roam terminals while logining application server.
S304, the heart beat cycle that application server reports according to roam terminals judges that whether roam terminals is for logining first, wherein, there are two kinds of situations in login first, be the first login of roam terminals while using for the first time, another kind is that roam terminals detects that the login first of carrying out while change has occurred self-position.As being login first, carry out heart beat cycle negotiation by the mode that sends heart beat cycle negotiation message with roam terminals, the step S204 of concrete negotiations process in can embodiment shown in Figure 2 is to step S210;
Wherein, roam terminals generally compares by the positional information of local record relatively with from the positional information of the current area of mobile network's air interface broadcast, thereby finds himself whether to be positioned at a new position, need to again carry out login first.
Wherein, application server can according to when login heart beat cycle field mark determine whether to login first, for example, when this is designated 0 or when negative, can determine that this roam terminals is for login first, deny, while being greater than 0 positive integer as being designated in this field, can determine that this roam terminals is non-login first.
As shown in Figure 4, roam terminals is logined first, carries current location information and heart beat cycle (being made as 0).Application server finds that the current heart beat cycle of terminal is 0, and can identify this roam terminals is to login first, issues the initial heart beat cycle X of network side
1, and inform that roam terminals starts heart beat cycle negotiations process.
Roam terminals is received after replying of application server, uses heart beat cycle X
1issue next heartbeat message, application server issues next heart beat cycle value X in replying after receiving
2=X
1+ Y.
After roam terminals is received and replied, use heart beat cycle X
2issue next heartbeat message, application server issues next heart beat cycle value X in replying after receiving
3=X
2+ Y.
If roam terminals finds that it sends after heartbeat message and do not receive replying of application server, roam terminals heart beat cycle is set to X
n-1.(heart beat cycle of supposing the current use of roam terminals is X
n).
Roam terminals informs that application server adopts X between the two upper while once logining
n-1as heart beat cycle.
The core of above-mentioned heart beat cycle negotiations process is to adopt heartbeat automatic detection mechanism to seek the heart beat cycle of optimizing, and both can adopt the pattern at every turn increasing taking regular length as unit, also can adopt the elongated pattern of increasing degree.
For example, fixed step size 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, obtain preferably heart beat cycle by above-mentioned flow process, can reduce network traffics between application server and roam terminals, and reduce the power consumption of terminal.
Fig. 5 is according to the schematic flow sheet of the method for the detection roam terminals heart beat cycle of another embodiment of the present disclosure.
As shown in Figure 5, this embodiment can comprise the following steps:
S502, the heart beat cycle that application server reports according to roam terminals judges that whether roam terminals is for logining first;
S504, as being login first, judges on application server, whether to have recorded the heart beat cycle corresponding with the current location information of the roam terminals reporting;
S506, as record not, carry out heart beat cycle negotiation by the mode and the roam terminals that send heart beat cycle negotiation message, the step S204 of concrete negotiations process in can embodiment shown in Figure 2 is to step S210, otherwise, directly the heart beat cycle corresponding to the current location information with the roam terminals reporting of record is sent to roam terminals;
In this embodiment, even if roam terminals is login first, if application server records the heart beat cycle that the current location information of the roam terminals reporting is corresponding, this roam terminals of logining first is also consulted without again this current location being carried out to new heart beat cycle, to save system resource.
In the above-described embodiments, if roam terminals is not received yet from the heartbeat message of application server and is replied in the time of the single message time-out time F arrival sending after heartbeat message, should retransmit immediately heartbeat message, reply or reach the maximum number of retransmissions C of prior setting until receive heartbeat message in time-out time F, if do not receive yet after retransmitting C time that heartbeat message replys, confirm that this heartbeat message sends unsuccessfully.Wherein time-out time F can be set to 5 seconds, and maximum number of retransmissions can be set to 2.
It is pointed out that and adopting after retransmission mechanism, in the time of the heart beat cycle of determining after consulting, also need to consider the impact of number of retransmissions and propagation delay time.Therefore, can upgrade based on single message time-out time (, maximum transmitted time delay) and number of retransmissions the value of the heart beat cycle after consulting.
For example, heartbeat message has not been realized after the negotiation of heart beat cycle by re-transmission, and between roam terminals and application server, real heart beat cycle is the maximum transmitted time delay that heart beat cycle after the negotiation in embodiment illustrated in fig. 2 deducts single message again, that is, and and X
n-1-F.
Next the method for by Fig. 6 a and Fig. 6 b, the heart beat cycle after consulting being revised is elaborated.
Fig. 6 a considers in disclosure embodiment that the heart beat cycle under the extreme case of heartbeat message propagation delay time calculates the relevant schematic diagram of method of adjustment.
As shown in Figure 6 a, in heartbeat negotiations process, as terminal is used X at the i-1 time
i-1for heart beat cycle and retransmit and successfully receive that heartbeat replys after D heartbeat message, terminal is at the i time use X
ifor the cycle and retransmit and successfully receive that heartbeat replys after E heartbeat message, Y
i=X
i-(D+1) × F, the heart beat cycle after the current negotiation of terminal record should be Z
i=Max(Y
i, Y
i-1).When terminal is used X
nwhile repeatedly not receiving response message for cycle transmission heartbeat message, this negotiations process is ended, and the result of negotiation is that heart beat cycle is Z
n-1, instead of initial X
n-1.That is to say, terminal is logined after application server later, should be every Z
n-1– (C+1) × F sends heartbeat message and thinks that contingent normal message re-transmission reserves (C+1) × F duration, if application server is at Z
n-1in cycle, do not receive the heartbeat message of terminal, think disconnecting.Wherein, generally, application server in heartbeat negotiations process, the heart beat cycle value X issuing first
1should meet X
1> (C+1) × F.
Fig. 6 b is at the last schematic diagram that sends heartbeat message for three times of terminal based on method described in Fig. 6 a.
As shown in Figure 6 b, different from Fig. 6 a, it is last twice that Fig. 6 b shows, and, successfully sends the situation of heartbeat message the N-2 time and the N-1 time that is.The revised heart beat cycle of this twice correspondence is respectively Y
n-2and Y
n-1.Because terminal is retransmitted and all do not received replying of application server transmission through C time in the time sending heartbeat message the N time, cause terminal to be connected termination with application server, therefore, terminal is by Y
n-2and Y
n-1in maximum as holding consultation and revised heart beat cycle, again report Y to application server in login when application server in terminal
n-2and Y
n-1in maximum.
Login first the roam terminals of application server for certain position, may wait because link is unstable various factors to cause it that re-transmission has occurred in the time of the heart beat cycle of determining after consulting, and the heartbeat message retransmitting before arrival fire compartment wall is all lost, this situation has affected the accuracy of the heart beat cycle corresponding with this position to a certain extent, therefore, next further improve the accuracy of the heart beat cycle after negotiation by the statistical method in Fig. 7.
Fig. 7 is according to the schematic flow sheet of the method for the detection roam terminals heart beat cycle of an embodiment more of the present disclosure.
As shown in Figure 7, this embodiment can comprise the following steps:
S702, application server judges whether the roam terminals of login is front M the roam terminals that same position place logins at first, wherein, whether position is identical is according to the structure of mobile communications network and fixed, only have roam terminals and application server the firewall box of communication link process of process do not change, can think that position is identical, for example, the roam terminals that is positioned at a prefecture-level city can be the identical roam terminals in position, be positioned at even in some cases a roam terminals inside the province, also may be the identical roam terminals in position, this depends on the actual deployment situation of fire compartment wall at network.Taking CDMA 1X network as example, adopt the combination of SID and NID generally just can distinguish " diverse location " that meet above-mentioned feature.
S704, if, no matter this roam terminals whether for logining first, all carry out heart beat cycle negotiation by the mode and the roam terminals that send heart beat cycle negotiation message, the step S204 of concrete negotiations process in can embodiment shown in Figure 2 is to step S210, otherwise, directly the heart beat cycle corresponding to the current location information with the roam terminals reporting of record is sent to roam terminals;
It is to be noted, in step S704, as the negotiation of need execution heart beat cycle, can further judge, whether certain login is the login first in this position, login first in this way, the initial heart beat cycle of the network side issuing according to application server starts to hold consultation, if this login is not the login first in this position, initial heart beat cycle that on the one hand can side Network Based starts to consult, on the other hand, in order to improve negotiation speed, also can start to consult by maximum heart beat cycle corresponding to same position based on having recorded on application server, can significantly improve like this negotiation speed.
S706, all complete after heart beat cycle negotiation at M roam terminals, the maximum of choosing in M heart beat cycle after negotiation is recorded as the heart beat cycle corresponding with the same position reporting, use in order to follow-up other roam terminals in same position login, or in the time that this M roam terminals is logined again, the heart beat cycle recording in the heart beat cycle reporting and application server is compared, as difference, by heart beat cycle value sending value roam terminals more accurately in statistical significance.
This embodiment can retransmit the egregious cases of all losing by certain roam terminals heartbeat message in negotiations process and be down to minimum on the impact of heart beat cycle.
In the above-described embodiments, in the time that roam terminals is under CDMA 1X network, the current location information of roam terminals can be SID(System Identification, system identification) or SID and NID(Network Identification, NID) combination, it is to be noted that SID is more accurate than utilizing SID to carry out home position information separately with the compound mode of NID.
Describe as an example of the terminal in CDMA 1X network example below.
CDMA 1X terminal can obtain BSID(Base Station Identity code, base station identity code) information, wherein, BSID is made up of SID, NID and Base Station ID.CDMA1X terminal, in the time of login application server, is carried above-mentioned information.The heart cycle data of application server after can be taking SID or SID+NID as dimension records corresponding negotiation.In the time that application server finds that the positional information correspondence of CDMA 1X terminal to report has had the heart cycle data of optimization to record, directly notify CDMA 1X terminal to adopt these data as heart beat cycle length from now on.In the time that application server finds that the positional information correspondence of terminal to report does not have heart cycle data to record, application server and CDMA 1X terminal start heart beat cycle and consult flow process.
One of ordinary skill in the art will appreciate that, whole and the part steps that realizes said method embodiment can complete by the relevant hardware of program command, aforesaid program can be stored in a computing equipment read/write memory medium, this program is in the time carrying out, execution comprises the step of said method embodiment, and aforesaid storage medium can comprise the various media that can be program code stored such as ROM, RAM, magnetic disc and CD.
