Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of an application scenario of a message pushing method according to an embodiment of the present invention. Fig. 2 is a schematic flow chart of a message pushing method according to an embodiment of the present invention. The method of the present invention is applied to the push management server 1. The method comprises the steps that a push management server 1 obtains average push time delay of push servers 3 in a preset push server set, wherein the push server set comprises a manufacturer push server set and a non-manufacturer push server set; if a push request sent by a service terminal 2 is received, the push management server 1 judges whether a manufacturer push mode is adopted to push a message to a user terminal 4 according to the push request, wherein the push request comprises a message to be pushed; if a manufacturer pushing mode is adopted to push a message to a user terminal 4, the pushing management server 1 screens a pushing server 3 with the minimum average pushing time delay from the manufacturer pushing server set as a target pushing server, and sends the message to be pushed to the target pushing server so as to push the message to be pushed to the user terminal 4 by the target pushing server; if the information is not pushed to the user terminal by the manufacturer in a pushing mode, the pushing management server 1 screens out the pushing server 3 with the minimum average pushing time delay from the pushing server set as a target pushing server, and sends the information to be pushed to the target pushing server so that the target pushing server pushes the information to be pushed to the user terminal 4.
Fig. 2 is a flowchart illustrating a message pushing method according to an embodiment of the present invention. As shown, the method comprises the following steps S1-S4.
S1, average pushing time delay of each pushing server in a preset pushing server set is obtained.
Wherein the push server set comprises a vendor push server set and a non-vendor push server set.
In this solution, messages may be pushed to the user terminal via a plurality of different push servers (i.e. via different push channels). The preset push server set is a set formed by all selectable push servers. The push server set comprises a manufacturer push server set and a non-manufacturer push server set, and the manufacturer push server set is a set formed by push servers provided by manufacturers of the user terminals. The non-manufacturer push server set is a set consisting of push servers provided by a third-party service organization (non-user terminal manufacturers). Pushing messages to the user terminal via a push server provided by the manufacturer of the user terminal enables a higher reach rate (i.e. more users may receive messages).
In a specific implementation, in order to determine the performance of the push server, in the present solution, an average push delay of the push servers in the push server set is obtained. The push delay refers to the time required from pushing a message from the push server to the user terminal receiving the message. The average push delay is the average push delay of the push server. The average push time delay is short, which indicates that the performance of the push server is high, and the user terminal can receive the message pushed by the push server in a short time. The average push time is prolonged, which indicates that the performance of the push server is low.
In an embodiment, referring to fig. 3, the above step S1 specifically includes the following steps S11-S12.
And S11, judging whether the current time reaches a preset time node.
In specific implementation, since the performance of the push server is not constant, the push server will also continuously develop optimization. Therefore, in the scheme, only the average push delay of the push server in the current period of time is counted.
Specifically, whether the current time reaches a preset time node is judged. It should be noted that the time node can be set by those skilled in the art according to actual situations. For example, the time node may be set to the zero point of monday every week, which is not particularly limited in this embodiment.
And S12, if the current time reaches the preset time node, acquiring the average push time delay of each push server in the push server set in the characteristic statistical interval.
The end point of the characteristic counting interval is the preset time node, and the starting point of the characteristic counting interval is the time starting point of the preset duration before the preset time node.
In specific implementation, if the current time reaches a preset time node, the average push delay of each push server in the push server set in a feature statistical interval is obtained. The end point of the characteristic statistical interval is a preset time node, and the start point of the characteristic statistical interval is a time start point of a preset time length before the preset time node, and it should be noted that the preset time length can be set by a person skilled in the art. For example, the preset duration may be 7 days.
For example, in one embodiment, the predetermined time node is set to zero on Monday. The end point of the characteristic statistical interval is the zero point of monday, and the start point of the characteristic statistical interval is the time start point 7 days before the zero point of monday (i.e., the zero point of last monday). Therefore, the average push time delay of each push server in the push server set can be updated every other week. The accuracy of the data is ensured.
And if the current time does not reach the preset time node, acquiring the average push time delay of each push server in the push server set in the characteristic statistical interval when the current time reaches the preset time node.
In one embodiment, referring to fig. 4, the above step S12 specifically includes the following steps S121 to S123.
And S121, sending a pushing statistical data acquisition request to the pushing server, wherein the pushing statistical data acquisition request comprises the characteristic statistical interval.
In specific implementation, the push management server sends a push statistical data acquisition request to the push server. And the pushing statistical data acquisition request comprises the characteristic statistical interval.
Correspondingly, when receiving a pushing statistical data acquisition request sent by a pushing management server, the pushing server acquires pushing statistical data of the pushing server in the characteristic statistical interval, and sends a response message containing the pushing statistical data to the pushing management server.
And S122, receiving a response message returned by the push server, wherein the response message comprises push statistical data of the push server in the characteristic statistical interval, and the push statistical data comprises push time when the push server pushes the message and receiving time when the user terminal receives the message pushed by the push server.
In a specific implementation, the push management server receives a response message returned by the push server. The response message comprises pushing statistical data of the pushing server in the characteristic statistical interval, and the pushing statistical data comprises pushing time when the pushing server pushes the message and receiving time when the user terminal receives the message pushed by the pushing server.
S123, determining the average pushing time delay of the pushing server according to the pushing statistical data.
In a specific implementation, the push management server determines the average push delay of the push server according to the push time of the push server when pushing the message and the receiving time of the user terminal when receiving the message, which are included in the push statistical data.
In an embodiment, the step S123 specifically includes the following steps: and S1231.
S1231, according to the following formula
Figure BDA0002100331030000071
And calculating the average time delay T of the push server.
Wherein n is the total number of messages pushed by the push server in the characteristic statistical interval, i is the serial number of the messages, and t is the number of the messages 2i Push time, t, when pushing a message for the push server 1i And the receiving time is the receiving time when the user terminal receives the message pushed by the push server.
S2, if a pushing request sent by the service terminal is received, judging whether a manufacturer pushing mode is adopted to push a message to the user terminal according to the pushing request, wherein the pushing request comprises a message to be pushed.
In specific implementation, when receiving a push request sent by a service terminal, a push management server determines whether to push a message to a user terminal in a manufacturer push mode according to the push request. The push request includes a message to be pushed. The vendor push mode refers to pushing messages through a push server in a vendor server set. Pushing messages through the push servers in the vendor server set can achieve a higher reach rate (i.e., enable more users to receive messages).
Specifically, if a message needs to be pushed in a manufacturer pushing manner, the service terminal adds a preset first identifier in the pushing request, otherwise, the service terminal adds a preset second identifier in the pushing request.
Correspondingly, the push management server judges whether to adopt a manufacturer push mode to push the message to the user terminal according to the characteristic identifier (the first identifier or the second identifier) contained in the push request.
In an embodiment, the push request includes a feature identifier, where the feature identifier is a preset first feature identifier or a preset second feature identifier, referring to fig. 5, and the step S2 specifically includes the following steps S21 to S23.
S21, judging whether the characteristic identifier contained in the push request is a preset first identifier or not.
In specific implementation, the push management server determines whether the characteristic identifier in the push request is a preset first identifier.
It should be noted that the special identifier is used to indicate the action performed by the terminal. The special identifier is a word, a symbol or a combination of a word and a symbol. For example, in one embodiment, the first identifier is the number "1"; the second identifier is the number "0".
And S22, if the characteristic identifier in the pushing request is the first identifier, judging that the message is pushed to the user terminal by adopting a manufacturer pushing mode.
In a specific implementation, if the feature identifier in the push request is the first identifier, it is determined to push a message to the user terminal in a vendor push manner.
And S23, if the characteristic identifier in the pushing request is not the first identifier, judging that the message is not pushed to the user terminal in a manufacturer pushing mode.
In a specific implementation, if the characteristic identifier in the push request is not the first identifier (i.e., is the second identifier), it is determined that the message is not pushed to the user terminal in the vendor push manner.
S3, if a manufacturer pushing mode is adopted to push messages to the user terminal, a preset number of pushing servers are screened out from the manufacturer pushing server set according to the sequence of average pushing time delay from small to large to serve as first target pushing servers, the first target pushing server with the lowest resource utilization rate in the first target pushing servers is obtained to serve as a second target pushing server, and the messages to be pushed are sent to the second target pushing server so that the second target pushing server can push the messages to be pushed to the user terminal.
In specific implementation, if a manufacturer pushing mode is adopted to push messages to a user terminal, a preset number of pushing servers are screened from the manufacturer pushing server set as first target pushing servers according to the sequence that the average pushing time delay is from small to large.
Further, a first target push server with the lowest resource utilization rate in the first target push servers is obtained as a second target push server, and the message to be pushed is sent to the second target push server so that the second target push server pushes the message to be pushed to the user terminal.
It should be noted that the predetermined number can be set by a person skilled in the art according to experience, for example, in an embodiment, the predetermined number can be set to 3.
Therefore, on the premise of using a manufacturer pushing mode, the average pushing time delay in a manufacturer pushing server set is small, and the currently most idle (the resource utilization rate is lowest) pushing server is selected as the second target pushing server to push the message to be pushed, so that the message pushing efficiency is ensured while the reaching rate is ensured.
S4, if the information is not pushed to the user terminal in a manufacturer pushing mode, a preset number of pushing servers are screened out from the non-manufacturer pushing server set according to the sequence that the average pushing time delay is from small to large to serve as third target pushing servers, a third target pushing server with the lowest resource utilization rate in all the third target pushing servers is obtained to serve as a fourth target pushing server, and the information to be pushed is sent to the fourth target pushing server so that the fourth target pushing server can push the information to be pushed to the user terminal.
In a specific implementation, if a manufacturer pushing mode is not adopted to push a message to a user terminal, a preset number of pushing servers are screened from the non-manufacturer pushing server set as a third target pushing server according to a sequence that an average pushing time delay is from small to large.
Further, a third target push server with the lowest resource utilization rate in the third target push servers is obtained as a fourth target push server, and the message to be pushed is sent to the fourth target push server so that the fourth target push server pushes the message to be pushed to the user terminal.
Therefore, the push server which has smaller average push time delay and is most idle at present (the resource utilization rate is lowest) can be selected as the second target push server to push the message to be pushed, so that the efficiency of message push is ensured while the reach rate is ensured.
It should be noted that the predetermined number can be set by a person skilled in the art according to experience, for example, in an embodiment, the predetermined number can be set to 3.
By applying the technical scheme of the embodiment of the invention, the average pushing time delay of each pushing server in a preset pushing server set is obtained, if a pushing request sent by a service server is received, a preset number of pushing servers are screened out from the non-manufacturer pushing server set according to the sequence from small to large of the average pushing time delay to serve as third target pushing servers, a third target pushing server with the lowest resource utilization rate in the third target pushing servers is obtained to serve as a fourth target pushing server, the message to be pushed is sent to the fourth target pushing server, and the message to be pushed is pushed to a user terminal by the fourth target pushing server, so that the message can be pushed to the user terminal by using the pushing server with the lowest average pushing time delay, the message pushing efficiency is ensured, and the use experience of a user is improved.
