Description
Technical Field
The present disclosure relates to the field of mobile communications, and in particular, to a method and system for determining a network status of a terminal.
Background
The method for acquiring the network state of the terminal currently indicates the reporting state of the terminal by adding a field in a signaling, and sends an indication message for indicating that the UE needs to report the service state of the UE to the terminal (UE); and receiving and acquiring the service state reported by the UE.
For example, a Call STATUS LIST (Call STATUS LIST) is added to an TRACKING AREA UPDATE REQUEST message of the terminal, so that the UE reports the service STATUS to the network side through a TRACKINGAREA UPDATE REQUEST message carrying the Call STATUS LIST.

In addition, in the prior art, the control module at the NB terminal side may adjust parameters such as the PSM state duration according to the actual situation to achieve the purpose of reducing power consumption. However, this type of technique is also biased towards the terminal side and does not obtain the PSM status from the network side.

For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
Fig. 1 is a flowchart illustrating an embodiment of a method for determining a network status of a terminal according to the present disclosure.
In step 110, S1 signaling in a DPI (Deep Packet Inspection) signaling system is collected. The DPI signaling system acquires signaling of interaction between all terminals and a network side from an EPC core network, and an S1 interface is a communication interface between a base station and the core network. The terminal in this embodiment is an NB-IOT terminal.
In step 120, the network status of the terminal is determined based on the time point of the S1 signaling event and the parameters negotiated by the core network and the terminal in the S1 signaling. For example, a time point T1 when the network issues a Context release command parameter is obtained based on the S1 signaling; acquiring an attach accept parameter issued by a network based on an S1 signaling, wherein the attach accept parameter carries a running time T of an activation timerStator(ii) a Run time T based on T1 and activation timerStatorDetermining a power saving mode PSM time point T1+ TStator(ii) a Comparing the current time T with the PSM time point T1+ TStatorAnd determining whether the terminal is in the PSM state.
In this embodiment, through the DPI signaling system, the signaling event related to the PSM status is recorded without direct interaction with the terminal, and based on the time point of the S1 signaling event and the parameter negotiated between the core network and the terminal in the signaling, the network status of the terminal can be determined from the network side, so that the control efficiency and accuracy of the application platform on the terminal can be improved.
Fig. 2 is a flowchart illustrating another embodiment of the method for determining the network status of the terminal according to the present disclosure.
At step 210, S1 signaling in the DPI signaling system is collected.
In step 220, a time point T1 of issuing a Context release command parameter by the network and an attach accept parameter issued by the network are obtained based on the S1 signaling, where the attach accept parameter carries the running time T of the activation timerStator. Wherein, TStatorAnd negotiating parameters for the terminal and the EPC core network.
In step 230, based on T1 and TStatorDetermining a power saving mode PSM time point T1+ TStator。
In step 240, it is compared whether the current time T is greater than or equal to the PSM time point T1+ TStatorIf so, go to step 250, otherwise, go to step 260.
In step 250, it is determined whether the terminal is in the PSM state. At this time, the terminal does not respond to any message on the network side, such as paging, downlink data, and the like.
In step 260, it is determined whether the terminal is in an active state or an idle state. At this time, the terminal may respond to the message on the network side.
In another embodiment, if the terminal is already in the PSM state, it may be further determined when the terminal exits the PSM state. As shown in fig. 3, when the terminal stops transmitting and receiving data, the base station side performs idle detection and starts a timer, which is based on the configuration of the base station, for example, 20S. After the Timer is overtime, the network side releases S1 connection, RRC (radio resource Control) connection, the terminal enters IDLE state, and starts Active Timer TStatorFor example 180S. Timer TStatorAfter a timeout the terminal enters a PSM state in which it does not respond to any instructions of the core network. The terminal can exit the PSM state under two conditions, namely, the terminal actively reports data and the terminal performs T when the TAU period arrivesAnd updating the AU. Therefore, the following steps as shown in fig. 4 may also be included after step 250:
in step 270, a time point T2 when the network issues the attach accept parameter is obtained based on the S1 signaling.
In step 280, the time point T3 when the network issues the TAU accept parameter and the time T required for the terminal to perform TAU are obtained based on the S1 signalingTAU。
Step 270 and step 280 may be executed simultaneously or not sequentially.
In step 290, based on T2 and TTAUDetermining the time T2+ T of the terminal for the next TAUTAUOr based on T3 and TTAUDetermining the time T3+ T of the terminal for the next TAUTAU。
In step 2100, if the current time T is greater than or equal to T2+ TTAUOr, the current time T is greater than or equal to T3+ TTAUIt is determined that the terminal exits the PSM state.
In the above embodiment, through the DPI signaling system, under the condition that the DPI signaling system does not interact directly with the terminal, the signaling event related to the PSM state is recorded, and based on the time point of the S1 signaling event and the parameter negotiated between the core network and the terminal in the signaling, it can be determined from the network side whether the terminal enters the PSM state or not, and when the terminal exits the PSM state, thereby improving the control efficiency and accuracy of the application platform on the NB terminal, and reducing the load pressure and processing efficiency caused by the instruction and data cache of the application platform.
For example, when the application platform prepares to issue data or a control command, it first queries whether the terminal is reachable, i.e. in PSM state, if it is reachable, it issues the command, and if it is not reachable, it will be sent out temporarily, so that it is avoided that the terminal is sent out and retransmitted blindly in the state that it is not known whether the terminal is reachable, and the number of terminals is generally large, which is easy to cause backlog of commands and downlink data, and brings pressure to the platform.

In this embodiment, through the DPI signaling system, the signaling event related to the PSM status is recorded without direct interaction with the terminal, and based on the time point of the S1 signaling event and the parameter negotiated between the core network and the terminal in the signaling, the network status of the terminal can be determined from the network side, so that the control efficiency and accuracy of the application platform on the terminal can be improved.
Fig. 6 is a schematic structural diagram of another embodiment of the system for determining the network status of the terminal according to the present disclosure. The system comprises an acquisition module 610, an analysis module 620 and a judgment module 630, wherein the analysis module and the judgment module belong to sub-modules in a state analysis judgment module.

The analysis module 620 is configured to obtain, based on the S1 signaling, a time point T1 at which the network issues a Context release command parameter, and an attach accept parameter issued by the network, where the attach accept parameter carries an operation time T of the activation timerStator. Wherein, TStatorAnd negotiating parameters for the terminal and the EPC core network.
The determining module 630 is used for determining the difference between T1 and TStatorDetermining a power saving mode PSM time point T1+ TStatorIf the current time T is greater than or equal to the PSM time point T1+ TStatorDetermining that the terminal is in the PSM state; if the current time T is less than PSM time T1+ TStatorThen it is determined that the terminal is in an active state or an idle state.
In another embodiment, the analysis module 620 is further configured to obtain a time point T2 when the network issues the attach reception parameter based on the S1 signaling; s1 signaling-based acquisition of time T3 of issuing tracking area update receiving parameters by network and time T required by terminal to update tracking areaTAU(ii) a The determining module 630 is further configured to determine whether to perform the operation based on T2 and TTAUDetermining the time T2+ T of the next tracking area update of the terminalTAUOr based on T3 and TTAUDetermining the time T3+ T of the next tracking area update of the terminalTAU(ii) a If the current time T is more than or equal to T2+ TTAUOr, the current time T is greater than or equal to T3+ TTAUIt is determined that the terminal exits the PSM state.
In the above embodiment, through the DPI signaling system, under the condition that the DPI signaling system does not interact directly with the terminal, the signaling event related to the PSM state is recorded, and based on the time point of the S1 signaling event and the parameter negotiated between the core network and the terminal in the signaling, it can be determined from the network side whether the terminal enters the PSM state or not, and when the terminal exits the PSM state, thereby improving the control efficiency and accuracy of the application platform on the NB terminal, and reducing the load pressure and processing efficiency caused by the instruction and data cache of the application platform.
