Technical Field

The present disclosure relates to the field of wireless communication technology, and in particular, to an information processing method and apparatus, a communication device, and a storage medium.

Background

The terminal or User Equipment (UE) accesses the network, and the power of the terminal is consumed for developing services. The limited terminal volume power tends to be limited. Especially, for some internet of things terminals, the power supply is more limited.

In order to be more efficient and to extend the power usage time as much as possible, some power saving mechanisms and power saving modes have been developed to save terminal power. For example, the terminal of the internet of things is not always in an operating state, and when the terminal is in a non-operating state (such as a dormant state), the electric quantity of the terminal can be saved, so that the standby time is prolonged. For another example, in an area where the communication signal is not covered, the terminal may continuously search for a cell, which may increase power consumption of the terminal, so in an area where the communication signal is not covered, it is desirable that the terminal does not perform cell search, network connection, and the like, in order to save power of the terminal.

As shown in fig. 2, a star chain composed of satellites sat_1 and sat_2 provides communication services for Tracking Areas (TA) 1 and TA 2. The UE is in TA1. At time T1, sat_2 moves over TA1 to provide signal coverage, and the UE may access the network through the signal provided by sat_2. By the time T2, the TA1 region has no satellite to provide signal coverage due to satellite movement, at which time the UE cannot access the network. By time T3, sat_1 moves into TA1 region to provide signal coverage, at which time the UE can access the network again. Since the area where the UE is located cannot support the continuous coverage of the communication signal, the UE is in a discontinuous coverage scene. Aiming at the scene, the communication signal coverage conditions of the areas where the UE is located at different time points need to be determined, so that the UE can conveniently communicate with the network under the condition of communication signal coverage, and the communication between the network and the UE is suspended under the condition of no communication signal coverage, thereby achieving the purpose of saving the power consumption of the UE and ensuring the normal and orderly development of the communication service of the UE under the discontinuous coverage scene.

As shown in fig. 3, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a core network device, and the method includes:

s110: acquiring ephemeris information of a satellite;

S120: and determining satellite coverage information of the UE according to the ephemeris information and the current position information of the UE.

The information processing method provided by the embodiments of the present disclosure may be performed by a core network device including, but not limited to, an access control function (Access Management Function, AMF). Also illustratively, the first network device may also be an access control device of a non-terrestrial network (Non Terrestrial Network, NTN).

The core network device acquires ephemeris information of the satellites, wherein the ephemeris information is used for recording satellite motion conditions, namely, position data of each satellite at any moment can be determined according to the ephemeris information, so that coverage change conditions of satellite signals transmitted by the satellites in an area where the UE is located, namely, the satellite coverage information, can be determined according to the ephemeris information of the satellites and the current position information of the UE.

In some embodiments, the UE may be a less mobile UE or a stationary UE. Illustratively, the UE may be a smart home device or a smart office device, etc. Aiming at the UE with smaller mobility or the fixed UE, the current position of the UE is the position area where the UE is located for a long time. The area where the UE is located can be determined according to the current location information of the UE, and the area can be TA, RA, NTN cell such as satellite cell, or the like.

The current location information of the UE indicates the location of the UE. And determining a Tracking Area (Tracking Area TA) or an NTN cell and the like where the UE is currently located according to the current position information of the UE.

The current location information may include: the longitude and latitude of the current position of the satellite and/or the TA code of the TA or the cell identification of the cell.

Determining the change information of the satellite signal coverage area according to the ephemeris information of the satellite, and combining the area of the UE to know

Knowing the satellite coverage of the area in which the UE is located, this satellite coverage can be indicated by the satellite coverage information described above.

Illustratively, the satellite coverage information includes, but is not limited to, at least one of:

the satellite covers the time information of the area where the UE is located;

the satellite covers the time information of the area where the UE is located next time;

and the satellite currently covers the residual time information of the area where the UE is located.

The embodiment of the disclosure provides a method for determining satellite coverage information, which determines whether communication is performed between a network and UE according to the satellite coverage information, so as to ensure that communication service of the UE in a discontinuous coverage scene is normally developed.

In some embodiments, as shown in fig. 4A, the method further comprises:

S130A: determining a power saving parameter of the UE according to the satellite coverage information;

S140A: and sending the power saving parameter to at least one of the UE and access network equipment.

If the UE works according to the power saving parameter, the power consumption of the UE can be saved relative to the normal standby state of the UE.

If the power saving parameter of the UE is determined according to the satellite coverage information, the UE may be in a non-operating state such as a sleep state when there is no satellite signal coverage, and in an operating state when there is satellite signal coverage. The power consumption of the UE in the working state is higher than that of the UE in the non-working state such as the dormant state, so that the power consumption of the UE is saved on one hand, and the load of the network equipment for transmitting data is reduced on the other hand.

For example, the core network device may directly send the power saving parameter to the UE, for example, through a Non-Access Stratum (NAS) message. Or the core network device sends the power saving parameter to the access network device (e.g. eNB or gNB), and then the access network device sends the power saving parameter to the UE through an RRC message or an access layer message such as MAC CE. The access network device includes, but is not limited to: the access network device of the UE.

In some embodiments, the core network device may send the power saving parameters to the UE and the access network device, respectively, so that both the UE and the access network device may receive the power saving parameters from the core network device and know the power saving parameters of the UE.

In some embodiments, as shown in fig. 4B, the method further comprises:

S130B: transmitting the satellite coverage information to at least one of access network equipment and the UE;

the satellite coverage information is used for at least one of the access network equipment and the UE to determine the power saving parameter of the UE.

The core network device sends the satellite coverage information to the access network device or the UE. The access network device or the UE can determine the power saving parameter of the UE according to the satellite coverage information, and at this time, the UE switches between the working state and the non-working state according to the power saving parameter, thereby saving the power consumption of the UE.

Or, the UE determines whether to communicate with the network device according to the satellite coverage information after receiving the satellite coverage information, or the access network device determines whether to communicate with the UE according to the satellite coverage information after receiving the satellite coverage information, or the network device determines whether to communicate with the UE according to the satellite coverage information.

In another embodiment, the method may further comprise:

and after the satellite coverage information is determined, judging whether to initiate communication with the UE according to the satellite coverage information.

For example, the core network device may determine whether to initiate communication with the UE based on its own determined satellite coverage information. For example, when it is determined that the area where the UE is located is not covered by satellite signals according to the satellite coverage information, communication with the UE is not initiated. And when the satellite signal coverage exists in the area where the UE is located and the communication requirement exists according to the satellite coverage information, initiating communication with the UE.

In some embodiments, the power saving parameter comprises at least one of:

eDRX parameters;

PSM parameters.

eDRX parameters include, but are not limited to eDRX cycle and PTW.

As shown in fig. 5, during each eDRX cycle, the UE may receive downlink data only during the paging time window (Paging Time Window, PTW), and the terminal is in a sleep state during other times during the eDRX cycle. The UE does not receive downlink data in the sleep state. The eDRX mode takes into account low power consumption of the UE and communication services having certain requirements on time delay, for example, remote shutdown gas service and the like.

During each eDRX period, the UE listens to the paging channel for reception of downlink data during the PTW according to the DRX period. The DRX cycle is short, e.g., 1.28s, 2.56s, 5.12s, or 10.24s, etc.

The eDRX mode involves two important eDRX parameters, the duration of the eDRX cycle and the duration of the PTW, respectively. The core network configures eDRX parameters to the UE through an initial registration or a registration update procedure. In addition, the core network may also send eDRX parameters to the base station via paging messages, and then the base station sends the eDRX parameters to the UE. For example, when paging the UE, the core network sends the eDRX parameter to the base station with the eDRX parameter carried in a paging message.

The PSM parameter includes a duration parameter of a timer. The timer herein includes, but is not limited to: a timer (T3324) and/or a TAU timer (T3412) is activated.

After entering PSM, UE is in dormant state at least in timing time of TAU timer outside timing range of activation timer, and paging message and down going data are not received.

There are two ways for the UE to wake up:

the first is that the UE transmits uplink data;

the second is that the TAU timer expires.

Referring to fig. 6, the PSM parameter involves two timers, T3412 and T3324, respectively. Where T3412 is a TAU timer and T3324 is an activation timer. The DRX cycle is a period in which the UE listens for paging messages, and in a timing range of the activation timer, the UE is reachable because the UE periodically listens for paging messages even in an idle state, i.e., the UE periodically wakes up to enter a working state and listens for paging messages.

In the timing range of the TAU timer outside the activation timer, the UE is not reachable, i.e. the UE does not receive downlink data, nor does it make any measurements of the serving cell and neighbor cells.

The values of the two timers T3324 and T3412 are configured to the UE by the core network, which typically configures the above parameters to the UE when the UE attaches to the network and performs TAU.

In summary, in the embodiments of the present disclosure, the power saving parameter determined according to the satellite coverage information includes at least the eDRX parameter and/or the PSM parameter described above.

Illustratively, the satellite coverage information includes at least duration information for a first duration and a second duration;

the first duration is as follows: the duration of the area where the satellite covers the UE;

the second duration is: and the satellite covers the interval duration between the starting moments of the areas where the UE is located twice.

The first time length indicates the duration of coverage of the satellite by the preset area, and the second time length indicates the interval time length between the revealing time between two adjacent coverage satellites by the satellite, so that the duration of non-coverage of the area where the UE is located by the satellite can be determined according to the second time length and the first time length. For example, if the first duration is Ts1 and the second duration is Ts2, the duration of the area where the UE is located and is not covered by the satellite is: ts2-Ts1.

In other embodiments, the satellite coverage information may further include: duration information of the first duration and the third duration;

the first duration is as follows: the duration of the satellite coverage preset area; the preset area is an area where the current position of the UE is located;

the third duration is as follows: the satellite covers the interval duration of the preset area twice.

In some embodiments, the first duration is used for determining a duration of a paging time window PTW in an eDRX cycle in eDRX parameters of the power saving parameter; the duration of the PTW does not exceed the first duration;

and/or the number of the groups of groups,

the second duration is used for determining the duration of the eDRX cycle; the duration of the eDRX cycle is not less than the second duration;

and/or the number of the groups of groups,

the first duration is used for determining the duration of an activation timer in the PSM parameter of the power saving parameter; the duration of the activation timer does not exceed the first duration;

and/or the number of the groups of groups,

the second duration is used for determining the duration of a tracking area update TAU timer in the PSM parameter; the duration of the TAU timer is not less than the second duration.

If the duration of the PTW is less than or equal to the first duration, that is, the time when the UE is in the working state such as the awake state under the eDRX mechanism is just the time when the satellite covers the area where the UE is located, the UE can be successfully paged if the UE is paged at this time.

If the eDRX cycle is less than or equal to the second duration, the UE is in the non-working state such as the sleep state or is mostly distributed in the time where the area where the UE is located is not covered by the satellite signal. At this time, the network side cannot communicate with the UE based on the satellite signal, and the UE enters the sleep state to save power consumption just.

In an embodiment, the duration of the activation timer in the PSM parameter is determined according to the first duration, and the duration of the activation timer is less than or equal to the first duration, so that the UE is reachable in the first duration, and if the network side needs to page the UE, downlink data may be sent to the UE through the transmission of a paging message.

The duration of the TAU timer in the PSM parameter is determined according to the second duration, and the duration of the TAU timer is less than or equal to the second duration, so that the UE is just the time without satellite signal coverage when in a low power consumption non-operating state where downlink data is not received and no measurement is performed on the cell.

In some embodiments, as shown in fig. 7, the method further comprises:

S131C: communicating with the UE in the first duration;

and/or the number of the groups of groups,

S132C: and not communicating with the UE in the second time period except the rest of the first time period.

Of course, the UE may also be in an operating state without satellite coverage, but the network device may determine, according to the satellite coverage information, what time periods are in communication with the UE and what time periods are not in communication with the UE.

S131C may include at least one of:

transmitting downlink data to the UE in a first duration;

and sending a downlink instruction to the UE in the first duration, wherein the downlink instruction is used for indicating the UE to report the state of the UE or the acquired data and the like. For example, the UE is an intelligent home device, and the downlink indication may be used to instruct the UE to report a home work completion status of the UE or an operation status of the UE;

receiving uplink data reported by UE in a first duration;

and receiving a service request and the like sent by the UE in the first time period.

Of course, the above is merely a specific example of communication with the UE in the first time period, and the specific implementation is not limited to this example.

Meanwhile, in the remaining second duration from which the first duration is removed, the core network device not communicating with the UE may include at least one of:

in the remaining second time length from which the first time length is removed, not sending downlink data to the UE;

and in the remaining second time length from which the first time length is removed, not sending downlink signaling to the UE.

The downlink data may be downlink data sent to the UE by the peer terminal device or AF, etc. The downlink signaling includes, but is not limited to, signaling such as mobility management, session management, etc. of the core network device and the UE.

In this way, the communication between any network device and the UE on the network side is within the time when the satellite signal coverage occurs in the area where the UE is located, so that ineffective attempts to communicate with the UE during the period when the area where the UE is located is not covered by the satellite signal are reduced.

In some embodiments, the method further comprises at least one of:

receiving the ephemeris information from an access network device;

receiving the ephemeris information from a management device;

the ephemeris information is configured on a core network device.

The above-mentioned manner of obtaining the ephemeris information by the core network device is provided, and the specific implementation manner is not limited to any one of the above-mentioned manners.

For example, the core network device receives ephemeris information from access network devices including, but not limited to, base stations.

The management device may be a satellite management device and/or an access network management device. The operation and maintenance personnel can perform configuration management on the satellite and the access network equipment through the management equipment.

As shown in fig. 8, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a UE, and the method includes:

S210: and acquiring a power saving parameter, wherein the power saving parameter is determined according to satellite coverage information of an area where the UE is located.

The UE may acquire the power saving parameters determined according to the satellite coverage information of the region in which the UE is located.

determining the eDRX parameter and/or PSM parameter according to the satellite coverage information from the core network equipment;

or alternatively, the process may be performed,

and receiving the power saving parameters determined by the core network equipment according to the satellite coverage information.

The UE may determine the power saving parameter according to the satellite coverage information sent by the core network device, or may receive the power saving parameter from the core network device or the access network device, but the power saving parameter is determined according to the satellite coverage information regardless of the power saving parameter received from the core network device or the access network device. In some embodiments, the satellite coverage information includes at least duration information for a first duration and a second duration;

Wherein, the first duration is: the duration of the area where the satellite covers the UE;

the second duration is: the time interval between the starting moments of the adjacent two coverage preset areas of the satellite.

In some embodiments, the first duration is used for a duration of a paging time window PTW within an eDRX cycle in the eDRX parameter; the duration of the PTW does not exceed the first duration;

and/or the number of the groups of groups,

And/or the number of the groups of groups,

and the second duration is used for determining the duration of a TAU timer in the PSM parameter, and the duration of the second timer is not less than the second duration.

If the eDRX period and the PTW in the eDRX parameter are set according to the first duration and the second duration, the area where the UE is located can be reached under the condition that satellite signals are covered, so that communication between the UE and other devices is facilitated, and the non-working state with low power consumption is entered under the condition that the area where the UE is located is not covered by satellite signals, so that the power consumption of the UE is reduced.

If the PSM parameter of the UE is set according to the first duration and the second duration, the timing duration of the TAU timer and the timing duration of the activation timer are set with reference to the second duration and the first duration, respectively, so that when the UE works according to the PSM parameter, it can be ensured that the area where the UE is located is reachable under the condition of satellite signal coverage, thereby facilitating communication between the UE and other devices, and entering a low-power-consumption non-working state under the condition that the area where the UE is located is not covered by satellite signals.

And/or the number of the groups of groups,

and not communicating with the UE in the second time period except the rest of the first time period.

The network device (e.g., AMF) obtains ephemeris information. The ephemeris information is used for recording satellite motion conditions, namely, the position data of each satellite at any moment can be determined according to the ephemeris information. The ephemeris information may be obtained from a wireless access device (e.g., a gNB), a network management device (e.g., a gNB network management, or a satellite management network element), or may be configured on a network device.

The network device AFM and the like determine satellite coverage information for User Equipment (UE) according to the ephemeris information and current position information of the UE, and the network device at least comprises: a first period of time Ts1 and a second period of time Ts2.

The first time period is used to represent a coverage time period, and during the time period, the satellite provides continuous coverage for an area where the UE is located. The second duration is used to represent a duration from one coverage start time to a next coverage start time. The UE pages reachable within a first time period.

For example, starting at time T1, the satellite provides network coverage for the UE, which is reachable. Starting at time T2, the satellite moves out of the coverage area and the UE is not reachable. Starting at time T3, the satellite again provides coverage for the UE, which is reachable. The first duration is ts1=t2-T1 and the second duration is ts2=t3-T1.

The network device may further determine parameters such as DRX parameters, eDRX parameters, and/or PSM parameters according to the satellite coverage information. For example, the determined eDRX cycle duration is not less than the second duration, the PTW duration is not more than the first duration, etc.

The network device provides the satellite coverage information to the UE, and an access device.

The network device determines whether to initiate interaction with the UE based on the satellite coverage information, where the interaction with the UE includes initiating a paging request, triggering initiation of a service request, and the like. The interaction with the UE is initiated for a first time period and ended beyond the first time period. The network does not initiate any interaction with the UE for the remaining second time period exceeding the first time period.

And the UE judges whether to initiate network interaction according to the satellite coverage information, wherein the network interaction comprises an initial registration request, a registration update request, a service request, a PDU session operation request and the like.

The UE can determine DRX parameters, eDRX parameters, PSM parameters and the like according to the satellite coverage information.

The access device determines whether to initiate interaction with the UE and the network device, for example, whether to initiate a broadcast message, according to the satellite coverage information.

And the access equipment determines parameters such as DRX, eDRX, PSM and the like according to the satellite coverage information.

When the eDRX parameter negotiation is carried out between the UE and the network, the network equipment (AMF) determines the eDRX parameter according to the satellite coverage information used by the access of the UE and returns the eDRX parameter to the UE and the gNB.

Referring to fig. 12, an information processing method provided by an embodiment of the present disclosure may include:

1a, the UE sends a registration request, wherein the registration request can be used for requesting eDRX parameters; illustratively, the UE accesses the 5G core network through a satellite, and sends a registration request, where the registration request includes eDRX parameters, where the eDRX parameters include eDRX cycle duration, PTW duration, and the like, and recommended values.

1b, gNB sends a registration request to AMF, wherein the registration request is used for requesting eDRX parameters and carrying user location information and ephemeris information of the UE. Specifically, when the registration request message arrives at the gNB, the gNB sends the user location information (User Location Information, ULI) and ephemeris information to the AMF along with the registration request message. The user location may be one of the aforementioned current location information of the UE.

When the AMF receives the registration request message, the UE is judged to use the non-geosynchronous satellite access according to the received RAT type, the ephemeris information is requested to the gNB, and the gNB returns the ephemeris information to the AMF according to the request. Or the AMF requests the management function to acquire the ephemeris information, and the ephemeris information may be configured on the AMF.

2. The AFM determines satellite coverage information, and illustratively, the AMF determines satellite coverage information related to the UE, for example, a satellite coverage duration (first duration Ts 1) and a satellite coverage interval duration (second duration Ts 2) of an area where the UE is located, according to the ephemeris information and the user location information of the UE. When AMF determines eDRX parameters in combination with user subscription information and/or local strategy, the satellite coverage information is also required to be considered, namely, the determined eDRX period duration cannot exceed the second duration, and if so, the second duration is taken as the eDRX period duration; and if the determined PTW duration cannot exceed the first duration, taking the first duration as the PTW duration.

The local policy may determine whether eDRX parameters need to be determined for the UE.

3. The remaining registration steps are performed.

4. The AMF sends a registration acceptance message to the UE, wherein the message contains eDRX parameters.

5. The UE stores eDRX parameters.

the AMF returns the eDRX parameters to the UE in a registration success message. The AMF can also send the eDRX parameter to the gNB, and the gNB controls downlink data and downlink signaling to be sent to the UE in Ts1 according to the eDRX parameter.

And the UE stores the eDRX parameter, and can ensure that the UE has satellite coverage and paging is reachable within the PTW duration according to the eDRX parameter. During eDRX periods beyond PTW periods, there is no satellite coverage and the UE remains dormant.

According to the embodiment, the discontinuous coverage of the satellite is fully considered by setting the eDRX parameter for the UE, so that the UE can be ensured to sleep under the condition that the satellite coverage is not available, and the purpose of saving power consumption is achieved.

The network device (AMF) may also determine satellite coverage information from ephemeris information obtained in the UE registration request and send the satellite coverage information to the UE and the gNB. The UE may determine when to initiate network interactions based on the satellite coverage information. The gNB may also determine when to send downstream data to the network based on the satellite coverage information. The implementation process may be as shown in fig. 13, and specifically may include:

1a, the UE sends a registration request, wherein the registration request can be used for requesting eDRX parameters; by way of example only, and in an illustrative,

the UE accesses the 5G core network through the satellite and sends a registration request. When the registration request message arrives at the gNB, the gNB sends User Location Information (ULI) and ephemeris information along with the registration request message to the AMF.

1b, gNB sends a registration request to AMF, wherein the registration request is used for requesting eDRX parameters and carrying user location information and ephemeris information of the UE. When the AMF receives the registration request message, the UE is judged to use the non-geosynchronous satellite access according to the received RAT type, the ephemeris information is requested to the gNB, and the gNB returns the ephemeris information to the AMF according to the request. Or the AMF requests the management function to acquire the ephemeris information, and the ephemeris information may be configured on the AMF.

The AMF determines satellite coverage information related to the UE, for example, a satellite coverage start time T0, a satellite coverage duration (first duration Ts 1) and a satellite coverage interval duration (second duration Ts 2) of an area where the UE is located, according to the ephemeris information and the UE location information.

3. The remaining registration steps are performed.

4. The AMF sends a registration accept message to the UE, which contains satellite coverage information, e.g. the information of Ts1 and Ts2 described above.

5. The UE stores satellite coverage information.

the AMF returns the satellite coverage parameters to the UE in a registration success message. The AMF can also send the satellite coverage parameters to the gNB, and the gNB controls downlink data and signaling to be sent to the UE in Ts1 according to the satellite coverage information.

The UE stores the satellite coverage parameters, and according to the satellite coverage parameters, the UE can be ensured to have satellite coverage in the Ts1, paging can be kept to be reachable, no satellite coverage exists in the Ts2 exceeding the Ts1, and the UE is kept in a dormant state until the next second duration Ts2 starts.

According to the embodiment, the satellite coverage parameters are set for the UE, so that the UE can be ensured to sleep under the condition of no satellite coverage, and the purpose of saving power consumption is achieved.

The satellite coverage information described above may also be used for determination of PSM parameters. The implementation process is described as follows:

the UE requests the use of PSM in the attach procedure and/or the tracking area update procedure, and the recommended values of T3324, T3412 are included in the request message. The T3324 value is the time when the network can provide continuous coverage to the UE; the value T3412 is the difference between the time of starting to be in network coverage (the time of sending the request) and the time of next to be in network coverage, where there may be no network coverage between the two network coverage.

The network device (AMF or MME) receives the request message, determines satellite coverage information of the area where the UE is located according to the ephemeris information, further determines T3324 and T3412 values and sends PSM parameters to the UE and the access network device (eNB or gNB) in the attach accept and TAU accept messages.
