Because the uplink (MO) and downlink (MT) of VOLTE short message sending are all determined by the round-robin parameter of the registration phase through which IP short message gateway, the MO sending phase is determined according to the address stored in the Serving Call Session Control Function (S-CSCF) and the result obtained by the SMSC to the Home Subscriber Server (HSS) in the MT receiving phase.

Fig. 1 is a schematic diagram illustrating an architecture of an IP sms gateway communication according to the present invention.
In the gateway Pool, a plurality of IP short message gateways serve the same S-CSCF at the same time, as shown in fig. 1, after a user UE _ a accesses a network, all the accessed S-CSCFs set alternate selection parameters on an ENS in advance, and perform different address translations for the same domain name. Registering the address information of different IP short message gateways through REGISTER message REGISTER, and storing the address information in S-CSCF. The IP short message gateway sends the short message MO according to the registered address information, and simultaneously sends a file Update Request message (PUR) to the HLR/HSS through the IP short message gateway.
And sending the address information of the IP short message gateway to the HLR/HSS so that the IP short message gateway can receive the short message MT. Therefore, resource sharing and service load sharing can be realized among a plurality of IP short message gateways in the Pool.
Because the IP short message gateway in the current PooL does not support dynamic load balancing, the method depends on the static configuration realization of S-CSCF and SMSC. When the load of the IP short message gateway is unbalanced, the relative balance of the load can be achieved only by repeatedly modifying the distribution proportion and the weight of the S-CSCF and adopting a mode of manually transferring users, and the efficiency and the accuracy are very low.
In addition, although the factors causing the uneven load of the IP short message gateway are many, how to analyze the correlation of the factors can accurately find the factors which really affect the load change of the IP short message gateway, and the IP short message gateway is intervened according to the factors, thereby ensuring the load balance of the IP short message gateway and having no solution. Therefore, research on various factors and load balancing is necessary.
The embodiment of the invention provides a method for solving the problem of unbalanced load of an IP short message gateway under different factors, which enhances the load balancing capability of the IP short message gateway, enhances the automatic adjustment capability of the IP short message gateway in the face of sudden impact and realizes the optimized management and control of the IP short message gateway by predicting the load expected value of the IP short message gateway, finding the factor causing the IP short message gateway to conform to the unbalance, adopting a corresponding scheme for processing aiming at the factor and the like. Therefore, the flexibility of the IP short message gateway is improved, and the customer satisfaction is enhanced.
For better understanding of the present invention, the following describes a method, an apparatus, a device and a medium for processing load imbalance of an IP short message gateway according to an embodiment of the present invention in detail with reference to the accompanying drawings, and it should be noted that these embodiments are not intended to limit the scope of the present disclosure.
Fig. 2 is a flowchart illustrating a method for processing load imbalance of an IP short message gateway according to an embodiment of the present invention.
As shown in fig. 2, a method 200 for processing load imbalance of an IP short message gateway in the embodiment of the present invention includes the following steps:
and step S210, collecting the load value of each IP short message gateway in the gateway pool group at the current time point, and determining the load expected value of each IP short message gateway according to the load value.
In this step, the expected load value of each IP sms gateway can be predicted by the following formula (1).
Figure BDA0001775463060000051
Wherein k is time (unit: day), xkIs the load value of the IP short message gateway at the same time point on the previous k day, and E (X) is the predicted load periodThe threshold value P (x) is a probability function, and n is a natural number of 1 or more.
Step S220, when the deviation value of any load expected value from the predicted load expected threshold value is larger than a preset threshold value, determining a correlation coefficient of IP short message gateway load unbalance caused by each factor.
In the step, the load expectation value e (x) ' of the IP short message gateway at the current time point is judged whether the deviation value of e (x) ' from the predicted load expectation threshold value e (x) exceeds a preset threshold value α or not by using the formula (2), and when the deviation value of e (x) ' from the predicted load expectation threshold value e (x) exceeds a preset threshold value α, the IP short message gateway is considered to have load fluctuation and needs to intervene.
|E(X)’-E(X)|≥α (2)
In addition, when it is determined that the IP sms message gateway needs to intervene, it needs to further determine what kind of factor the load imbalance of the IP sms message gateway is caused by. And (4) calculating a correlation coefficient of each factor causing the load unbalance of the IP short message gateway through a formula (3).
In one example, the factors may include: the sending quantity of the short message MO, the receiving quantity of the short message MT, the number of registered users, the alarm quantity and the like.
Figure BDA0001775463060000061
Wherein i is time (unit: hour), xiThe load value of the IP short message gateway when the time point is i; y isiIs a measure of the factor at time point i,
Figure BDA0001775463060000062
is the average of the load values and is,
Figure BDA0001775463060000063
is the mean of the measured values of the factors; r is a correlation coefficient, and n is a natural number of 1 or more.
Step S230, when the absolute value of any correlation coefficient is greater than the preset correlation threshold, determining a factor corresponding to the correlation coefficient greater than the preset correlation threshold as an alternative factor.
In this step, it should be understood that the correlation coefficient r varies within a range from-1 to +1, and the closer the absolute value of r is to 1, the closer the factor is related to the straight line of the IP short message gateway; the closer to 0, the less closely the correlation.
When the absolute value of the correlation coefficient r is > 0.7, the degree of correlation is high, and this factor is used as a candidate.
It is understood that, for example: in the four factors of the short message MO sending quantity, the short message MT receiving quantity, the number of the registered users and the alarm quantity, if the absolute value of the correlation coefficient of the short message MO sending quantity is 0.9, the absolute value of the correlation coefficient of the short message MT receiving quantity is 0.8, the absolute value of the correlation coefficient of the number of the registered users is 0.6 and the absolute value of the correlation coefficient of the alarm quantity is 0.5. Then, since the absolute value of the correlation coefficient of the short message MO sending amount and the absolute value of the correlation coefficient of the short message MT receiving amount are both greater than 0.7, the short message MO sending amount and the short message MT receiving amount are used as alternative factors.
Step S240, selecting the candidate factor with the largest absolute value of the correlation coefficient from all the candidate factors as the optimal factor.
It is understood that, for example: the absolute value of the correlation coefficient of the short message MO sending quantity is 0.9, the absolute value of the correlation coefficient of the short message MT receiving quantity is 0.8, and the absolute value of the correlation coefficient of the short message MO sending quantity is the largest, so that the short message MO sending quantity is the most optimal factor.
And step S250, processing the load unbalance of the IP short message gateway according to the processing strategy corresponding to the optimal factor.
In this step, for example: when the sending quantity of the short message MO is the best factor, the load imbalance of the IP short message gateway needs to be processed according to a strategy aiming at the sending quantity of the short message MO.
By adopting the method of the embodiment of the invention, the deviation value of the real-time load expected value and the prediction threshold value is used as the standard for measuring whether the IP short message gateway load is unbalanced, so that the accuracy for judging whether the IP short message gateway load is unbalanced is improved, different processing schemes are provided according to different factors, the load balancing capacity of the IP short message gateway is enhanced, the automatic adjustment capacity of the IP short message gateway in the face of burst impact is enhanced, and the optimized management and control of the IP short message gateway are realized. Therefore, the flexibility of the IP short message gateway is improved, and the customer satisfaction is enhanced.
The following is a specific process for determining the correlation coefficient which causes the load unbalance of the IP short message gateway and corresponds to four different factors.
First, a short message MO sending amount sent from a serving call session control function S-CSCF to an IP short message gateway within a preset time period is obtained, where the preset time period is a time period before a current time point. And then determining a correlation coefficient of IP short message gateway load unbalance caused by the short message MO sending quantity according to the measured value and the load value of the short message MO sending quantity.
It can be understood that the measured value of the sending amount of the short message MO sent from the S-CSCF to the IP short message gateway and the load value of the IP short message gateway at the current time point are obtained 1 hour before the current time point. And (3) determining a correlation coefficient causing the load unbalance of the IP short message gateway by the short message MO sending quantity according to the formula (3), and when the absolute value of the correlation coefficient r is more than 0.7, listing the short message MO sending quantity as an alternative factor, otherwise, not considering the factor.
Secondly, the receiving quantity of the short message MT sent from the S-CSCF to the IP short message gateway in a preset time period is firstly obtained, wherein the preset time period is the time period before the current time point.
And then determining a correlation coefficient of the load unbalance of the IP short message gateway caused by the short message MT receiving quantity according to the measured value and the load value of the short message MT receiving quantity.
It can be understood that the measured value of the short message MT receiving amount sent from the S-CSCF to the IP short message gateway and the load value of the IP short message gateway at the current time point are obtained 1 hour before the current time point. And (4) determining a correlation coefficient causing the load unbalance of the IP short message gateway by the short message MT receiving quantity according to the formula (3), and listing the short message MT receiving quantity as an alternative factor when the absolute value of the correlation coefficient r is more than 0.7, otherwise, not considering the factor.
And thirdly, acquiring the number of registered users of the IP short message gateway. And then determining a correlation coefficient of IP short message gateway load unbalance caused by the number of registered users according to the number of registered users and the load value.
It can be understood that the number of registered users of the IP short message gateway and the load value of the IP short message gateway at the current time point are obtained 1 hour before the current time point. And (4) determining a correlation coefficient of IP short message gateway load unbalance caused by the number of registered users according to the formula (3), and when the absolute value of the correlation coefficient r is more than 0.7, listing the number of the registered users as an alternative factor, otherwise, not considering the factor.
Fourthly, the alarm quantity sent by the IP short message gateway is firstly obtained. And then determining a correlation coefficient of the IP short message gateway load unbalance caused by the alarm amount according to the alarm amount and the load value.
It can be understood that the alarm amount sent by the IP short message gateway and the load value of the IP short message gateway at the current time point are obtained 1 hour before the current time point. And (4) determining a correlation coefficient of the IP short message gateway load unbalance caused by the alarm quantity sent by the IP short message gateway according to the formula (3), and when the absolute value of the correlation coefficient r is greater than 0.7, listing the alarm quantity sent by the IP short message gateway as an alternative factor, otherwise, not considering the factor.
The following is a specific process for handling the load imbalance of the IP short message gateway by introducing corresponding handling strategies in the face of four different factors.
Fig. 3 is a diagram illustrating a normal MO transmission amount.
As shown in fig. 3, the normal MO flow is that UE _ a sends a MESSAGE to P-CSCF. And then according to the address information stored in the S-CSCF at the registration stage, the S-CSCF sends the MESSAGE MESSAGE to the corresponding IP SHORT MESSAGE gateway, and after receiving the MESSAGE MESSAGE, the IP SHORT MESSAGE gateway sends the constructed SHORT MESSAGE MO of the MAP _ MO _ FORWARD _ SHORT _ MESSAGE _ REQ to the SMSC.
At present, when the sending amount of the MO short messages is large, the MO short messages are relieved mainly by discarding the signaling in proportion according to the bearing capacity of an IP short message gateway. The higher the load of the IP short message gateway is, the more the discarded signaling is, and the higher the short message sending failure probability of the user MO is. Although the load of the IP short message gateway is reduced, the failure of sending the short message MO can cause the reduction of user perception and complaint, and simultaneously, the operation income is influenced.
Therefore, the following method is adopted for improvement.
The first case corresponds to the message MO sending volume:
firstly, the IP short message gateway stops receiving the short message MO sent by the S-CSCF, and sends the short message MO sent by the S-CSCF to the mobile service switching center MSC by utilizing the core network MME.
It is understood that, as shown in fig. 4, the IP short MESSAGE gateway rejects receiving the MESSAGE from the S-CSCF and instructs the MESSAGE to fall back to the access stratum MME. Compared with the short message MO flow in fig. 3, in fig. 4, the short message MO is no longer sent to the SMSC through the IP short message gateway with higher load. At this time, the IP sms gateway does not participate in route analysis, message transmission, etc., and thus, the load of the IP sms gateway is gradually reduced.
After the MESSAGE falls back to the access layer MME, the MME packs the MESSAGE MO in the SGsAP-UPLINK-UNITDATA MESSAGE by utilizing the existing network SGS interface of the MME and the MSC and sends the MESSAGE MO to the MSC. Compared with the original MO short message flow in fig. 3, the access layer MME and the MSC interface are the SGS interface of the existing network, and do not need to be modified, and the signaling bandwidth is sufficient, so that the short message MO requirement can be completely satisfied.
Then, MSC sends the short message MO sent by S-CSCF to short message service center SMSC according to CS network short message flow.
It can be understood that the MO short message is sent to the SMSC through the MSC according to the CS network short message flow. Compared with the original short message MO flow, the signaling path is prolonged, but the short message MO can be sent to the SMSC in real time, and the short message MO loss condition can not occur. Therefore, when the IP short message gateway of the IMS network has high load, the short message MO sent by the S-CSCF is received and is dredged to the SMSC through other ways without passing through the IP short message gateway, and the problem of service discard caused by overlarge load of the IP short message gateway is further effectively solved.
The second case corresponds to the reception amount of the short message MT:
firstly, the IP short message gateway takes the received M short messages MT as a high priority group to be sent to the user side, and simultaneously sends a timer updating message to the SMSC.
And then, the received N short messages MO are taken as a low priority group and sent to the SMSC.
Finally, according to the timer updating message, the time N of the timer is updated to M;
wherein M, N are integers of 1 or more, and M is 5N or more.
It should be noted that, when the sending amount of the short message MT is large, the reduction is mainly achieved by discarding the signaling in proportion according to the bearing capacity of the IP short message gateway. The higher the load of the IP short message gateway is, the more the discarded signaling is, and the user can not receive the short message MT at a later time.
Secondly, because the SMSC does not receive the response message of the IP short message gateway within the time T of the timer, the SMSC can send the message to the IP short message gateway again for secondary information delivery. Therefore, extra signaling overhead is brought to the IP short message gateway, and the load of the IP short message gateway continuously rises in a vicious circle, so that a larger signaling storm is brought to the network finally.
Therefore, the M short messages MT are sent to the ue as a high priority group. And the received N short messages MO are used as a low-priority group and sent to the SMSC. In addition, the IP short message gateway sends a timer updating message to the SMSC, the original timer time is N and is updated to the current timer time is M, the requirements M, N are integers which are more than or equal to 1, and M is more than or equal to 5N. This avoids a larger signalling storm due to message retransmission caused by timer timeout.
The third case corresponds to the user variance:
the user variance of the IP short message gateway is firstly determined.
When the user variance is larger than a preset user variance threshold value, the user to be moved on the IP short message gateway is moved to other IP short message gateways in the gateway pool group according to the moving proportion, wherein the moving proportion is the number of the user to be moved divided by the number of the registered users; the number of users to be migrated is equal to the number of registered users-the average number of registered users in the gateway pool group.
It can be understood that the user variance s of a plurality of IP short message gateways in the gateway pool group is used2To judge whether the number of registered users in the gateway pool is increased or whether the registered users are registered by multiple IP short message gateways in the gateway poolThe number of households increases.
Variance s2The smaller the size is, the higher the number of registered users of W IP short message gateways in the gateway pool is, which leads to the increase of the number of users and needs the capacity expansion of maintenance departments. Variance s2The larger the number of registered users representing individual IP short message gateways increases, and it is necessary to reduce the load by migrating users. Wherein the user variance s2The calculation is performed by the following formula (4):
Figure BDA0001775463060000101
x1、x2、x3……xWthe load values of W IP short message gateways in the gateway pool group at the current time point,
Figure BDA0001775463060000102
representing the average value of registered users of W IP short message gateways in a gateway pool, wherein W is an integer greater than or equal to 1;
counting the number of registered users of W IP short message gateways in the same gateway group at a time point, and if the number of registered users of the IP short message gateways deviates the maximum average value, moving the equipment user to other IP short message gateways according to a proportion; if the registered user number of the IP short message gateway is not the maximum deviation from the average value, other IP short message gateways in the gateway pool group are moved.
The fourth case corresponds to the alarm amount:
and carrying out fault maintenance on the IP short message gateway according to a preset alarm sequence.
It can be understood that this situation shows that the load increase of the IP short message gateway is closely related to the fault of the IP short message gateway, and the load is reduced by preferentially processing the fault, and the alarm level is selected to be the highest for processing.
The alarm processing sequence is emergency alarm > important alarm > general alarm > prompt alarm.
In an embodiment, after step S250 is executed, step S210 is returned to, and if a deviation value of the load value from the predicted load expected threshold is smaller than a preset threshold, the load of the IP short message gateway is considered to be normal at this time, and the system is stable; if the threshold value is larger than the preset threshold value, continuing to perform intervention operation according to the flow of the steps S210-S250. Repeating the above steps for 2-3 periods, the load of the IP short message gateway can be stabilized.
By the method of the embodiment of the invention, the deviation value of the load expected value of the IP short message gateway and the predicted load expected threshold value is used as the standard for measuring whether the IP short message gateway load is unbalanced. When the IP short message gateway has high load, the short message from the S-CSCF is dredged to the SMSC through other ways without passing through the IP short message gateway, so that the sending quantity of the short message MO is adjusted. By carrying out flow control on MT signaling data, the method not only can effectively relieve the load increase of the IP short message gateway, but also can avoid unnecessary signaling overhead and realize the adjustment of the receiving quantity of the short message MT. User variance s of multiple IP short message gateways in gateway pool group2The number of registered users of a single IP short message gateway in the gateway pool group is judged to be increased, or the number of registered users of a plurality of IP short message gateways in the gateway pool group is judged to be increased, so that the adjustment of the number of registered users is realized. And preferentially reducing the load by processing faults, and selecting the alarm with the highest level for processing.
The following describes in detail a processing apparatus for load imbalance of an IP short message gateway according to an embodiment of the present invention with reference to the accompanying drawings.
