The paging scheme provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 2 shows a flowchart of a paging method according to an embodiment of the present application, and the method 200 may be performed by a network side device. In other words, the method may be performed by software or hardware installed on the network-side device. As shown in fig. 2, the method may include the following steps.

S210, the network side equipment determines to communicate with the target terminal through a satellite.

For example, the network-side device may determine that the satellite network covers a target area in which the target terminal is located.

For example, in practical applications, since the area covered by the satellite network is predictable, the network-side device may determine the time at which communication with the target terminal may be performed through the satellite. For example, the network side device may predict when the satellite network may cover the target area where the target terminal is located or the network side device presumes the target area where the target terminal is located (i.e., the target area where the target terminal may be located).

In the embodiment of the present application, the satellite network may be a network through satellite access (satellite access), for example, the target terminal may access a satellite cell through a satellite. Alternatively, the satellite network may be a network relayed through a satellite (satellite backhaul), for example, the target terminal may access a terrestrial network, which in turn relays through the satellite.

In an embodiment of the present application, the target area may include at least one of the following and/or a part of at least one of the following: at least one target Tracking Area (TA), at least one target Radio Access Area (RA), at least one target cell (cell). For example, the target area may include multiple TAs, or multiple RAs, or multiple CELLs, or a portion of a TA, a portion of a RA, or a portion of a CELL, or a combination of a portion of a RA and a portion of a CELL, or a combination of one or more TAs and a portion of a RA, or the like, and embodiments of the present application are not limited.

In the embodiment of the application, the target terminal can access a target network, and the target network can comprise at least one of the following: a network accessed through a satellite, a network relayed through a satellite. For example, the target terminal accesses the network cell through a satellite, or the target terminal accesses a terrestrial network, which relays through a satellite.

S212, after the network side equipment waits for the target duration, paging the target terminal.

In the embodiment of the application, when the network side equipment determines to communicate with the target terminal through the satellite, the target terminal is not immediately paged, but is paged after waiting for the target time length, so that the problem that the network congestion is caused by the fact that the network side equipment tries to access the network in a short time because the network side equipment sends paging information to the target terminal with a large number of target terminals in a short time when the network side equipment determines to communicate with the target terminal with a large number of target terminals through the satellite is avoided.

In one possible implementation manner, in order to further alleviate network congestion, the target duration corresponding to each target terminal is not identical among a plurality of target terminals that communicate with the network side device through a satellite.

For example, when the network side device discovers that the satellite cell covers the target area, if there are a large number of UEs waiting for PAGING in the target area, the network side device delays the target UEs for a certain time (for example, different target UEs delay different times, or different target UEs may delay different times), and then pages each target UE.

In one possible implementation, the target duration may be determined according to at least one of:

(1) The target terminal receives the preparation time required by the downlink message; the preparation time may be a time period required for downlink synchronization between the target terminal in the target area and the satellite network after the satellite network covers the target area, i.e. a downlink synchronization time period, or a time period from when the target terminal starts to cover the target terminal from the satellite network to when the target terminal can receive a downlink message of the satellite network. The target duration of the delay is determined according to the preparation time required by the target terminal to receive the downlink message, so that the network side equipment can initiate paging after the target terminal is ready to receive the downlink message. For example, assuming that "the downlink synchronization time period" or "the time period from when the target terminal starts to cover the target terminal from the satellite network to when the target terminal can receive the downlink message of the satellite network" is time1, it may be determined that the target time period of the target terminal is time2, and the value of time2 is greater than or equal to time1.

(2) Analysis information of the target terminal; wherein the analysis information includes, but is not limited to, at least one of: (a) statistics of the target terminal; and (b) prediction information of the target terminal. For example, the analysis information may be information acquired from a network data analysis function (Network Data Analytics Function, NWDAF), which may be determined by the NWDAF according to the behavior of the target terminal, e.g., a terminal is presumed to be in a sleep state at a time without receiving downlink information, and the network may calculate the target duration according to the time.

(3) A random value; the target duration may be the random value directly, or may be a duration calculated according to the random value.

(4) The identification of the target terminal; for example, the target duration is calculated according to the ID of the target terminal. For example, the different durations may be calculated based on a subscription permanent identity (Subscription Permanent Identifier, SUPI) and/or a subscription encrypted identity (Subscription Concealed Identifier, sui) of the target terminal, etc.

(5) The subscription value of the target terminal; for example, the target duration is calculated according to the subscription value of the target terminal, for example, if the subscription value of the target terminal is: and determining the target duration corresponding to the target terminal as time 3.

(6) The paging priority of the target terminal; for example allocation and reservation priorities (Allocation and Retention Priority, ARP) of pages of the target terminal.

(7) And the service information of the target terminal. For example, the target duration is determined according to the service type of the target terminal, for example, if the service type of a certain target terminal is an emergency service, the target duration corresponding to the target terminal may be shorter, for example, 0, i.e. not delayed. For another example, the target duration is determined according to the service quality (Quality of Service, qoS) of the target terminal, for example, if the QoS of a certain target terminal is shorter than the time delay requirement, the corresponding target duration is also shorter. For another example, the target duration is determined according to the priority (priority service) of the service of the target terminal, for example, if a certain target terminal is a multimedia priority service (Multimedia Priority Service, MPS) or a key service (Mission Critical Service, MCS), the corresponding target duration is shorter, for example, may be 0, that is, when it is determined that communication is performed with the target terminal through a satellite, that is, the target terminal is paged.

In one possible implementation manner of the embodiment of the present application, before S210, the method may further include: and the network side equipment determines that the satellite network does not cover the target area and stores downlink data or downlink signaling to be sent to the target terminal. Because the time that a certain geographic location area is in the coverage area of the satellite network can be predicted, the network side device can determine the time that the coverage area of the satellite network is lost (i.e. the state of the coverage area is changed to the state of the uncovered target area), after reaching the time, the network side device stores downlink data or downlink signaling to be sent to the target terminal, and when determining that communication is performed with the target terminal through the satellite (for example, when determining that the satellite network covers the target area where the target terminal is again covered or the network side device presumes that the target area where the target terminal is located is again covered), the network side device delays the corresponding target time period for the target terminal, and then pages the target terminal, so that the situation that paging messages are sent to more target terminals in a shorter time, and then the more target terminals attempt to access the network in a similar time after receiving the paging messages, so as to cause network congestion can be avoided.

For example, when a terminal device is used to access a satellite cell (e.g., a cell of a network through which the terminal is accessed by a satellite) to obtain service, one possible scenario is: a geographic location area (e.g., TA) is faced with predictable loss and restoration of satellite cell coverage. When satellite cell coverage for the geographic location area is lost, the network-side device may buffer downlink data or signaling for certain UEs, and when satellite cell coverage for the geographic location area is restored, the network-side device may send paging messages to those UEs. If a large number of UEs exist in the geographical location area, the network side device buffers downlink data for the UEs, and when the satellite cell covers the geographical location area, the network side device sends PAGING to the large number of UEs in a short time, and then the large number of UEs attempt to access the network almost simultaneously after receiving the PAGING, so that network congestion is caused. Therefore, in the embodiment of the present application, for these UEs, the paging message may be sent after a delay of not exactly the same duration. For example, if there are three target terminals UE a, UE B and UE C in the target area, the network side device may send the paging message to UE a after delaying for 0ms, send the paging message to UE B and UE C after delaying for 2ms, or send the paging message to UE a after delaying for 0ms, send the paging message to UE B after delaying for 2ms, and send the paging message to UE C after delaying for 3 ms.

In one possible implementation manner of the embodiment of the present application, the network side device may be a core network device. In one possible implementation, the core network device includes one of: an access and mobility management function (AMF) network element, a network function entity (NF) network element, a Session Management Function (SMF) network element, and a User Plane Function (UPF) network element. For example, the SMF network element may send paging related information, such as downlink data, to the AMF network element after waiting for the corresponding target duration. For another example, the UPF network element may send paging related information, such as downlink data, to the SMF network element after waiting for the corresponding target duration.

Thus, in one possible implementation, S212 may include: and after the network side equipment waits for the target duration, sending a paging message for paging the target terminal to access network equipment.

In another possible implementation manner, the network-side device may be an access network device. Thus, the S212 may include: and after receiving the first paging message sent by the core network equipment and paging the target terminal, the network side equipment waits for the target duration and then sends a second paging message to the target terminal.

In one possible implementation manner, the first paging message may carry indication information, where the indication information is used to instruct the network side device to send the second paging message to the target terminal after waiting the target duration after receiving the first paging message.

For example, the first paging message may include information as shown in table 1.

Table 1.

In one possible implementation manner, the indication information may include first information indicating the target duration, for example, the first information is a time value of the target duration.

In another possible implementation manner, the indication information may also include second information for determining the target duration. For example, the second information may include at least one of:

(1) Index of target duration; for example, the core network device may configure the corresponding relationship between each target duration and the index to the access network in advance, or the core network device and the access network device may agree on the corresponding relationship between each target duration and the index in advance, where the network side device indicates the corresponding index in the first paging message when sending the first paging message, so that the access network may obtain the corresponding target duration.

(2) Calculating the value and unit of the target duration; for example, a random value of the target time length and a unit (e.g., ms) of the target time length are calculated.

(3) Ephemeris information; for example, for determining various parameters of time, coordinates, azimuth, speed, etc. of the satellite.

(4) And analyzing information of the target terminal. The analysis information of the target terminal includes, but is not limited to, at least one of: statistics information of the target terminal and prediction information of the target terminal.

In S212, the network side device may send the second paging message to the target terminal after waiting for the target duration according to the indication information carried in the first paging message.

In one possible implementation manner, the indication information may not be carried in the first paging message sent by the core network device, and the network side device (i.e. the access network device) determines the waiting target duration and then sends the second paging message. Thus, S212 may include: and the network side equipment determines the target duration after receiving the first paging message, and sends a second paging message to the target terminal after waiting for the target duration.

By the technical scheme provided by the embodiment of the application, the time point of paging the target UE can be dispersed by delaying the target time length, so that a large number of target UEs are prevented from attempting to access the network in a short time, and network congestion can be relieved.

Fig. 3 shows a further flowchart of a paging method according to an embodiment of the present application, and as shown in fig. 3, the method 300 includes the following steps.

S310, the core network device determines that both UE1 and UE2 have downlink data or signaling to be transmitted, but UE1 and UE2 are not in coverage of the satellite cell, so the core network device does not transmit downlink data or downlink signaling of UE1 and UE2.

S312, the core network device determines that the target area enters the coverage area of the satellite cell, pages UE1 after determining delay time1, and pages UE2 after delay time 2.

When the core network device determines that the target area enters the coverage area of the satellite cell, UE1 or UE2 may be still in the target area, but may not be in the target area, for example, UE1 or UE2 has the target area but is not connected to the network, so the core network device presumes that UE1 or UE2 is still in the target area.

S314, when the time1 arrives, the core network equipment sends a first paging message for paging the UE1 to the access network equipment.

The core network may be an AMF network element, or other NF network elements, such as an SMF network element, etc., to perform the delay operation.

For example, if the delay action is performed at the SMF network element, the SMF network element sends the information related to the packet to the AMF network element after the delay, such as the following data. If the delay action is performed at the UPF network element, the UPF network element sends the information related to the packet to the SMF network element after the delay, such as downlink data.

S316, after receiving the first paging message, the access network device sends a second paging message to the UE 1.

And S318, when the time2 arrives, the core network equipment sends a third paging message for paging the UE2 to the access network equipment.

S320, after receiving the third paging message, the access network device sends a fourth paging message to the UE 2.

According to the technical scheme provided by the embodiment of the application, when the core network discovers that the target area enters the satellite coverage area, the time points of a large number of PAING target UE are dispersed through delay, so that a large number of UE are prevented from attempting to access the network in a short time, and network congestion is relieved.

Fig. 4 shows a further flowchart of a paging method according to an embodiment of the present application, and as shown in fig. 4, the method 400 may include the following steps.

S410, the core network device sends a first paging message for paging UE1 to the access network device.

S412, the core network device sends a second paging message paging UE1 to the access network device.

At S414, the access network device delays time1 (i.e., waits for time 1) after receiving the first paging message after determining that the target area enters the coverage area of the satellite.

The core network carries indication information in the first paging message and the second paging message respectively, indicates the access network equipment to delay time1 after receiving the first paging message, then transmits the paging message of paging UE1, delays time2 after receiving the second paging message, and then transmits the paging message of paging UE 2.

Or, another implementation manner is that the access network device automatically judges and determines the delay time X after receiving the first paging message or the second paging message, and then sends the paging message.

S416, the access network device sends a third paging message to UE 1.

S418, the access network device delays time2 (i.e. waiting time 2) after receiving the second paging message after determining that the target area enters the coverage area of the satellite.

S420, the access network equipment sends a fourth paging message to the UE 2.

According to the technical scheme provided by the embodiment of the application, when the access network discovers that the target area enters the satellite coverage area, after receiving the paging message, the access network distributes the time points of a large number of PAING target UE through delay, so that a large number of UEs are prevented from attempting to access the network in a short time, and network congestion is relieved.
