Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and in particular to an information processing method, apparatus, communication device, and storage medium. Background Technology

[0002] In satellite networks, if satellite access provides network services to User Equipment (UE), the signal coverage provided to the ground may be discontinuous due to insufficient satellites in the Starlink network or satellite beam interruptions. This means that when a UE accesses the network via satellite in a certain area, there may be periods without satellite signal coverage. Therefore, UEs need to consider the discontinuous coverage of satellite access during network access and service provision. In cases of discontinuous satellite access coverage, the UE's satellite coverage information needs to be known to ensure normal service operation. Currently, however, network devices cannot accurately obtain the UE's satellite coverage information. Summary of the Invention

Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several user equipment 110 and several base stations 120.

[0091] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones (or "cellular" phones), and computers with IoT user equipment capabilities. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment. Alternatively, user equipment 110 can also be a device from an unmanned aerial vehicle (UAV).

Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called a New Generation-Radio Access Network (NG-RAN).

[0093] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Medium Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack.

The implementation of network management device 130 is not limited in this embodiment.

[0099] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0100] To better understand the technical solutions described in any embodiment of this disclosure, some aspects of the related technology will be described first:

[0101] In some application scenarios, the discontinuous coverage of satellite access needs to be considered. For example, when there is no satellite signal coverage, the UE can be put into a sleep or power-saving state to conserve power. When satellite signal coverage is restored, the UE can be woken up in time to re-establish a connection with the network or resume services. Another example is when a network device sends signaling and / or data to a UE, it needs to determine whether the UE is reachable. If the UE is in a signal coverage area and is reachable, the network device sends the signaling and / or data to the UE. If the UE is in an area without signal coverage, the network device buffers the signaling and / or data. When the network device determines that satellite signal coverage has been restored for the UE, it sends the signaling / data to the UE. In short, when a UE uses satellite access to the network and there is discontinuous satellite access coverage, both the UE and the network device need to determine the UE's reachability based on satellite coverage when signaling and / or data is transmitted. Communication only occurs when the UE is reachable.

[0102] In one embodiment, the Application Function (AF) needs to be aware of the UE's satellite coverage information. For example, before initiating a service with a relatively long interaction time, the AF can obtain the UE's satellite coverage information from the network device and determine whether to initiate the service based on the UE's network coverage information. This reduces the possibility of the UE becoming unavailable before the service ends.

[0103] In one embodiment, the AF obtains the UE's satellite coverage information from the UE's current serving network (e.g., a Public Land Mobile Network (PLMN)); and determines service-related operations based on the UE's satellite coverage information. These service-related operations may include whether and / or when to conduct services. However, the serving network can only obtain satellite coverage information for the satellite access currently used by the UE; for example, if a handover between the access network and / or the serving network occurs, the AF cannot accurately obtain the UE's satellite coverage information.

[0104] like Figure 2 As shown, this disclosure provides an information processing method, executed by an AF, comprising:

[0105] Step S21: Send a first request to the serving network device, wherein the first request is used to request the satellite coverage information of the UE;

[0106] Step S22: Receive satellite coverage information sent by the service network device.

[0107] Here, the UE can be any mobile or fixed terminal. For example, the UE can be, but is not limited to, a mobile phone, computer, server, wearable device, vehicle terminal, roadside unit (RSU), game control platform, or multimedia device.

[0108] Here, the service network device can be a logical node or function that can be flexibly deployed in the service network, and there are no restrictions on the service network device.

[0109] In one embodiment, the serving network device includes, but is not limited to, at least one of the following:

[0110] Access and Mobility Management Function (AMF)

[0111] Session Management Function (SMF);

[0112] Policy Control Function (SCF);

[0113] Unified Data Management (UDM).

[0114] In another embodiment, the serving network device may be, but is not limited to, a source serving network device or a target serving network device.

[0115] Here, the source serving network device is the network device of the source serving network; the source serving network is the serving network before the serving network handover. The target serving network is the network device of the target serving network; the target serving network is the serving network after the serving network handover or the network accessed. For example, if the UE switches from the first serving network to the second serving network; the source serving network device is the network device of the first serving network; the target serving network device is the network device of the second serving network.

[0116] In yet another embodiment, the serving network device may be a Network Data Analytics Function (NWDAF). For example, the serving network device may be a source network data analytics function (S-NWDAF) or a target network data analytics function (H-NWDAF).

[0117] Here, satellite coverage information can be, but is not limited to, satellite coverage duration and / or satellite non-coverage duration. Here, the satellite coverage duration can be the duration during which a certain area is covered by satellite signals; the satellite coverage duration can also be the start time and / or end time of satellite signal coverage. Here, the satellite non-coverage duration can be the duration during which a certain area is not covered by satellite signals; the satellite non-coverage duration can also be the start time and / or end time of no satellite signal coverage. In the embodiments of this disclosure, satellite coverage can be satellite signal coverage; satellite non-coverage can be the absence of satellite signal coverage.

[0118] In another embodiment, the satellite coverage information can also be other information, as long as the satellite coverage duration and / or satellite non-coverage duration are determined based on the satellite coverage information; no restrictions are placed on the satellite coverage information here.

[0119] In one embodiment, the first request is used to request satellite coverage information of the UE for a first event. Here, the first event is used to indicate, but is not limited to, one of the following events: satellite coverage information of the UE; and reachability information of the UE. Thus, the satellite coverage range of the corresponding UE can be requested in response to the first event.

[0120] Thus, in this embodiment of the disclosure, the AF sends a first request to the serving network device, the first request being for requesting satellite coverage information of the UE; and receives satellite coverage information sent by the serving network device; this allows the AF to accurately obtain the UE's satellite coverage information from the serving network device. This is beneficial for the UE to determine whether it has satellite signal coverage based on the satellite coverage information; thereby, it is beneficial for the network device and the UE to conduct effective service interactions based on whether the UE has satellite signal coverage.

[0121] For example, when it is determined that the UE has no satellite signal coverage, the UE can be put into sleep or power-saving mode, and / or the network device can be prevented from sending data and / or signaling to the UE; this can save power consumption for both the UE and the network device, and reduce the probability that the UE will not receive data and / or signaling from the network device. Conversely, when it is determined that the UE has satellite signal coverage, the UE can be put into wake-up mode, and / or the network device can be prevented from sending data and / or signaling to the UE; this can increase the probability that the UE will receive data and / or signaling from the network device.

[0122] Here, network equipment can be a logical node, function, or device in the access network and / or core network. For example, the network equipment can be a base station.

[0123] This disclosure provides an information processing method, executed by an AF, comprising:

[0124] Based on the UE's satellite coverage information, determine whether the UE is conducting business within the current coverage time range; and / or,

[0125] Based on the UE's satellite coverage information, determine whether the UE will be able to conduct business within the next coverage time period.

[0126] Here, both the current coverage time range and the next coverage time range can be any length of time. For example, the current coverage time range and the next coverage time range can be 1 minute, 2 minutes, 10 minutes, 1 hour, etc.

[0127] In one embodiment, the duration of the current coverage time range is the same as the duration of the next coverage time range.

[0128] In another embodiment, the duration of the current coverage time range is different from the duration of the next coverage time range.

[0129] Here, conducting business can involve performing business-related operations; for example, it may include, but is not limited to, receiving and / or sending information. Here, information includes, but is not limited to, signaling and / or data.

[0130] For example, if the AF determines that there is satellite signal coverage within the current coverage time range based on the satellite coverage duration in the UE's satellite coverage information, then it determines that services will be provided within the current coverage time range; or, if the AF determines that there is no satellite signal within the current coverage time range based on the satellite non-coverage duration in the UE's satellite coverage information, then it determines that services will not be provided within the current coverage time range.

[0131] For example, if the AF determines, based on the satellite coverage information of the UE, that there is no satellite signal coverage within the current coverage time range and that there is satellite signal coverage within the next coverage time range, then it determines to carry out services within the next coverage time range; or, if the AF determines, based on the satellite non-coverage time range of the UE, that there is no satellite signal coverage within the current time range and that there is no satellite signal within the next coverage time range, then it determines not to carry out services within the current time range and not to carry out services within the next coverage time range.

[0132] Thus, in this embodiment of the disclosure, the AF can determine whether the UE can carry out services within the current coverage time range and / or the next coverage time range based on the UE's satellite coverage information; thereby improving the effectiveness of service delivery and saving UE power consumption, etc.

[0133] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0134] In some embodiments, sending a first request to the serving network device in step S21 includes: sending a first request to the serving network device via NEF;

[0135] Step S22, receiving satellite coverage information sent by the serving network device, includes: receiving satellite coverage information sent by the serving network device via NEF.

[0136] Here, NEF is a logical node or function of the core network; AF can be a logical node or function on the core network side, or it can be a logical node or function of a third-party platform.

[0137] This disclosure provides an information processing method executed by the AF, comprising: sending a first request to the serving network device via the NEF; the first request being used to request satellite coverage information of the UE;

[0138] Satellite coverage information is received by the NEF service network equipment.

[0139] Here, the satellite coverage information received by the NEF service network device can be: the satellite coverage information of the UE received by the NEF service network device.

[0140] Here, the AF sends a first request to the serving network device through the NEF, which can be: the AF sends a first request to the NEF; the NEF forwards the first request to the serving network device.

[0141] Here, the AF receives satellite coverage information sent by the NEF service network device, which can be: the NEF receives the satellite coverage information sent by the service network device and forwards the satellite coverage information to the AF.

[0142] Of course, in other embodiments, the AF may also send the first subscription to the serving network device through other logical nodes or functions in the communication device; and / or, the AF may also receive satellite coverage information sent by the serving network device through other logical nodes or functions in the communication device.

[0143] Thus, the first request sent by the AF can be forwarded through the NEF or other logical nodes or functions, so that the first request can be effectively sent to the serving network device; and / or, the satellite coverage information sent by the serving network device can be forwarded through the NEF or other logical nodes or functions, so that the AF can successfully receive the satellite coverage information.

[0144] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0145] In some embodiments, the serving network device includes: a source serving network device;

[0146] Step S21, which involves sending a first request to the serving network device, includes sending a first request to the source serving network device.

[0147] like Figure 3 As shown, this disclosure provides an information processing method, executed by an AF, comprising:

[0148] Step S31: Send the first request to the source service network device.

[0149] Here, the source serving network device can be, but is not limited to, at least one of the AMF, SMF, SCF, and UDM in the source serving network. For example, the source serving network device can be the source AMF or the source SMF, etc.

[0150] In some embodiments of this disclosure, the first request may be the same as the first request described in the above embodiments; the satellite coverage information may be the same as the satellite coverage information described in the above embodiments. For example, the first request is used to request the UE's satellite coverage information. The satellite coverage information may be, but is not limited to, satellite coverage duration and / or satellite non-coverage duration.

[0151] In one embodiment, step S31 may be: sending a first request to the source serving network device before the UE switches serving networks.

[0152] This disclosure provides an information processing method, executed by an AF, comprising: receiving satellite coverage information sent by a source serving network device. Here, the satellite coverage information of the UE is the satellite coverage information of the UE before the serving network handover.

[0153] In some embodiments, prior to step S31, the method further includes:

[0154] A second request is sent to the source serving network device, wherein the second request is used to request an event report of the serving network handover event; the event report includes the identification information of the target serving network.

[0155] This disclosure provides an information processing method executed by an AF, comprising: sending a second request to a source serving network device, wherein the second request is used to request an event report of a serving network handover event; the event report includes identification information of the target serving network.

[0156] In one embodiment, the second request is used to request the identification information of the target service network, which is: the identification information of the target service network of the service network switching event.

[0157] In other embodiments, the second request can also be used to request an event report of an access network event. In this case, the serving network accessed by the UE can be considered the target serving network; the event report may include the identification information of the accessed serving network.

[0158] Here, the identification information of the target service network can be any kind of information that can identify the target service network.
