The application layer and the open layer are internal operation management systems, and the third-party application adopts the network capacity opened in the form of calling API to form various business applications and provide services for end users. The capability layer provides API for the open layer and the application layer, shields the network realization complexity, and has the main functions of: mobility management, session management, terminal parameter query and configuration, etc., the overall architecture is shown in fig. 1.
The third party application management system needs to consider the standby state of the terminal when sending the downlink service, and if the terminal is in an unreachable state, the downlink service needs to be delayed to be issued or data caching needs to be performed. There are two main implementation schemes in the related art: according to the first scheme, when the terminal is in an unreachable state, the core network caches data, then calculates the latest reachable time of the terminal, and sends down the paging message when the latest reachable time arrives. And in the second scheme, when the terminal is in the unreachable state, the base station performs data caching, and when the terminal has a paging opportunity, paging is performed.

The present invention is described below with reference to scene embodiments.
The standby of the mobile internet of things terminal mainly has three states: PSM (power save mode), eDRX (extended DRX, enhanced discontinuous reception), IDLE state. Under different standby states, the terminal responds differently to paging, and under the PSM state, the terminal is in the deep sleep state and does not monitor paging, so that paging messages are lost if the network issues paging at the moment; in the eDRX state, the terminal monitors paging only in a PTW (paging time window), and paging messages issued by the network at other times are lost; in the IDLE state, the terminal monitors paging according to the DRX period and is reachable.
When the standby state of the terminal is eDRX, the PTW and the UE _ ID _ H, T eDRX,H And the length L of the PTW.
The third-party application management system at least comprises: a database management module, a terminal information management module, a communication management module, and a rights management module, wherein the terminal information management at least includes contents such as a terminal location, a service model, and a transmission mode, and the specific structure is shown in fig. 8.
Example one
In the embodiment, an algorithm of platform downlink service issuing time is added in the third-party application management system, and the algorithm gives when the platform can issue the service according to the standby state of the terminal and the relevant parameter setting.
The input part of the algorithm is the standby state and related parameters of the terminal, and mainly comprises the following parameters:
(1) standby state PSM: PSM active timer, TAU period, connection state of terminal and core network and link release time;
(2) standby state eDRX: PTW, T eDRX,H 、UE_ID_H、L；
(3) Idle state no parameter.
The relevant parameters of the standby state can be acquired from the connection management platform through the terminal information management module, and the connection management platform is acquired through a parameter query function of a service capability opening unit (SCEF).
Before calculation, superframe synchronization between the base station and the core network needs to be performed, and a reference time method can be adopted. Time synchronization is achieved through the NTP server, then a time point when the H-SFN is equal to 0 is configured, and then the H-SFN corresponding to the current time is calculated based on the reference. The method is a scheme commonly used in the industry and is not in the protection scope of the patent application.
The third-party application management system calculates the latest reachable time of the terminal according to the standby state and related parameters of the terminal, and transmits downlink data t seconds before the latest reachable time, and the purpose of setting the time t seconds ahead for transmission is to eliminate the time delay influence of a core network and a base station, so that the downlink service data can reach the terminal in the reachable state of the terminal.
A specific flow of an algorithm for issuing time of downlink service data of the third-party application management system is shown in fig. 9, and may include the following steps:
step 901: judging the standby state of the terminal, and if the terminal adopts the standby state of the PSM, executing step 902; if the terminal adopts the standby state of eDRX, executing the step 906; if the terminal adopts other standby states (e.g., Idle state) except PSM/eDRX, execute step 904;
step 902: judging the connection state of the terminal and the core network, and if the connection state is the connection state, executing a step 904; if the link is in the link release state, step 903 is executed;
here, if the terminal adopts the standby state of the PSM, the terminal information management module in the third party application management system obtains the PSM active timer and the TAU period of the terminal from the SCEF, and if there is downlink traffic to be sent, first, queries the connection state of the terminal and the core network.
Step 903: returning to the terminal link release time, judging whether the current time is less than the terminal link release time + PSM active timer-t, if so, executing step 904; otherwise, go to step 905;
step 904: directly sending downlink service data;
step 905: determining the sending time of the downlink service data as the releasing time of the terminal link + TAU period-t seconds;
step 906: judgment of T eDRX,H Whether the time is less than t seconds, if yes, executing step 904; otherwise, go to step 907;
here, if the terminal adopts the standby state of eDRX, the platform terminal information management module acquires PTW, T of the terminal from the SCEF eDRX,H UE _ ID _ H, L parameter, if the terminal has downlink service transmission, firstly judging T eDRX,H If it is less than t seconds.
Step 907: inquiring the connection state of the terminal and the core network, and if the connection state is the connection state, executing a step 904; if the link is in the link release state, go to step 908;
step 908: and returning to the releasing time of the terminal link, then calculating the starting point of the PTW nearest to the terminal according to the specification of section 36.3047.3 of the protocol, and determining the sending time of the downlink service data as the starting point-t seconds of the PTW.
Example two
In this embodiment, an algorithm of a third-party application management system downlink service issuing time is added to a core network MME network element, and input and output parameters and a specific flow of the algorithm are the same as those in the first embodiment, which is not described in detail herein. Before calculation, superframe synchronization between the core network and the eNB needs to be performed, and the superframe synchronization scheme is not within the scope of the present application.
The difference from the embodiment is that: the method for acquiring the parameters corresponding to the standby state of the terminal is to acquire the parameters from data stored in the core network, and parameter transmission by the SCEF and the connection management platform is not needed.
The second difference from the embodiment is that: when the third-party application management system carries out downlink service, the issuing time of the downlink service data is inquired through the connection management platform and the SCEF, at the moment, the core network carries out calculation of the issuing time of the downlink service and feeds the calculation back to the third-party application management system, and the third-party application management system carries out issuing of the downlink service data at the corresponding time after obtaining the issuing time.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
