Description

Access method, terminal equipment, network equipment and storage medium

Technical Field

The present application relates to, but is not limited to, the field of communications, and in particular, to an access method, a terminal device, a network device, and a computer readable storage medium.

Background

In the related art, a terrestrial carrier leases a fixed bandwidth and a frequency point to a satellite carrier, which results in that the leased bandwidth resource cannot be dynamically adjusted according to the real-time capacity of a Non-terrestrial network (Non-terrestrial Network, NTN) terminal user of the terrestrial carrier, and serious resource waste or resource shortage can be caused. Thus, for high-throughput broadband satellite communication systems, dynamic satellite bandwidth lease, i.e., dynamic frequency point lease, will be a trend. In the satellite frequency point dynamic renting scenario, the system dynamically adjusts the frequency point resources allocated to each tenant.

However, when the NTN terminal needs to re-access the network, since the frequency point is dynamically leased, if the NTN terminal accesses according to the frequency point allocated at the previous moment, the frequency point may be occupied by other tenants, which causes a problem of invalid access.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description is given of related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as an alternative, which all belong to the protection scope of the embodiments of the present application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.

The third generation partnership project (3rd Generation Partnership Project,3GPP) proposes a transparent repeating satellite based non-terrestrial network access network architecture upon which terrestrial operators can deploy respective satellite networks by renting fixed satellite bandwidths. Under the architecture, the following technical schemes exist in the existing network access frequency point detection flow: the traditional satellite network uses a single carrier, and the ground operator rents a fixed satellite bandwidth, and the terminal only carries out frequency point detection in the bandwidth, so that the frequency point information of the network-access wave beam can be obtained rapidly. In a New Radio (NR) system, a search grid of a primary synchronization signal is related to a frequency band, and a terminal determines a search grid to be used according to a currently searched frequency band. If the frequency ranges from 0MHz to 3000MHz, the synchronous grid is 1200kHz; the synchronous grid is 1440kHz in the frequency range of 3000-24250 MHz; in the frequency range 24250-100000 MHz, the synchronous grid is 17.28MHz; in an internet of things (Internet of Things, IOT) system, the synchronization grid is 100kHz. In NR Non-terrestrial network (Non-terrestrial Network, NTN) or IOT NTN systems, because the terrestrial operators lease a fixed satellite bandwidth, there is no problem of excessive main synchronization signal search time despite the large bandwidth characteristics of high-throughput broadband satellites.

Fig. 2 is a flow chart of an access method according to an embodiment of the present application, as shown in fig. 2, where the method is applied to the communication system 100 shown in fig. 1, and the method includes:

step 201, the network device broadcasts a frequency point list of each tenant in the set fixed frequency band.

The frequency point list of each tenant comprises a first frequency point list of the tenant to which the terminal equipment belongs; the first frequency point list comprises frequency point resources allocated to the tenant to which the terminal equipment belongs.

In this embodiment of the present application, before the network device broadcasts the frequency point list of the tenant to each tenant, the network device negotiates a fixed frequency band with each tenant in advance, and stores the fixed frequency band in the inside of each terminal under the tenant. Here, each terminal under the tenant has the same tenant identity.

It should be noted that the fixed frequency band is a very small frequency band of a plurality of frequency resources supported by the network device, so that occupation of the existing frequency resources can be reduced as much as possible.

In the embodiment of the present application, the network device periodically broadcasts, to the terminal under each tenant, a plurality of frequency point lists corresponding to all tenants in the set fixed frequency band. It should be noted that, the frequency point list of the tenant may be carried by a broadcast message or a system message.

In some embodiments, the network device may update the fixed frequency band pre-negotiated with each tenant periodically according to the number of access terminals of each tenant and the demand of the frequency point resources, and pre-store the updated fixed frequency band in the terminal device to which the tenant belongs. Here, the update period may be preset, or may be adjusted according to an actual scene, which is not particularly limited in this application. It should be noted that, the updated fixed frequency band is pre-stored in the terminal device to which the tenant belongs, before the network device broadcasts the frequency point list in the updated fixed frequency band.

Step 202, under the condition that the terminal equipment is awakened, the terminal equipment obtains a fixed frequency band set by a tenant to which the terminal equipment belongs and the network equipment.

In the embodiment of the present application, under the condition that the terminal device is awakened, the terminal device obtains the tenant to which the terminal device belongs and the fixed frequency band which is negotiated in advance by the tenant to which the terminal device belongs and the network device. Here, a plurality of terminals may be connected to one tenant, and a plurality of tenants may be corresponding to one fixed frequency band.

It should be noted that the terminal device being awakened means that the frequency of the signal received by the receiver of the terminal device is switched from being greater than or equal to the receiving frequency threshold value to being less than the receiving frequency threshold value. For example, the frequency at which the receiver receives a signal being greater than or equal to the receive frequency threshold includes the receiver being in an off state all the time, or the receiver being turned on once a week to receive the signal. The receiver receiving a signal having a frequency less than the receive frequency threshold comprises the receiver receiving the signal once every few minutes or seconds. Here, the setting of the reception frequency threshold may be specifically set according to the communication scenario.

In some embodiments, the terminal device being awakened may refer to the terminal device switching from a sleep mode or a shutdown mode to a normal operating mode.

For example, for some outdoor scenes, when the related terminal equipment to be detected needs to start to carry out inspection work, the related terminal equipment to be detected is awakened and is switched from a shutdown mode or a dormant mode to a normal inspection mode, namely, the related terminal equipment to be detected scans and detects a related area by means of an unmanned aerial vehicle, and real-time image return is completed in a larger inspection range based on the advantages of automatic cruising, high-definition aerial photographing and the like of the unmanned aerial vehicle.

For example, when the network quality is good and the power consumption is not strictly required, the terminal equipment to be detected is switched from the sleep mode to the normal monitoring mode, so that the terminal equipment to be detected communicates with the management platform server in real time, and the reporting of the monitored data information is completed.

In some embodiments, the network device first transmits a wake-up signal (Wake Up Signaling, WUS) to the terminal device, e.g., user Equipment (UE), before the terminal device is activated, the UE detecting the WUS at the corresponding instant. If the UE detects the WUS, the UE is activated.

Step 203, the terminal device obtains a first frequency point list of a tenant broadcasted by the network device received in the fixed frequency band.

The first frequency point list comprises frequency point resources distributed to tenants.

In the embodiment of the application, the first frequency point list can be effectively used by the terminal equipment at the current moment; may be received for a last cycle of the plurality of broadcast cycles; or may be received for the current one of a plurality of broadcast periods.

In the embodiment of the present application, after receiving a plurality of frequency point lists broadcasted by a network device in a fixed frequency band, a terminal device obtains a first frequency point list of a tenant to which the terminal device belongs from the plurality of frequency point lists based on a tenant identifier of the tenant to which the terminal device belongs.

In the embodiment of the present application, the first frequency point list includes frequency point resources allocated to the tenant, that is, frequency point information that can be accessed by the terminal device.

Here, when the network device allocates frequency points to each tenant, the network device may allocate continuous frequency points as much as possible. The frequency point information formed by the continuous frequency points can be represented by the starting point and the ending point of the frequency points without presenting each frequency point information one by one, so that the broadcasting resources are saved.

Step 204, the terminal equipment performs network access based on the frequency point resources.

In the embodiment of the application, the terminal equipment determines an access frequency point of the terminal equipment from the frequency point resources pre-allocated to the tenant, and performs network access based on the access frequency point. Here, the access frequency point may be a working frequency point at a previous time of the terminal device, or may be a new working frequency point.

The embodiment of the application provides an access method, which comprises the following steps: under the condition that the terminal equipment is awakened, acquiring a fixed frequency band set by a tenant to which the terminal equipment belongs and the network equipment; acquiring a first frequency point list of a tenant broadcasted by network equipment received in a fixed frequency band; the first frequency point list comprises frequency point resources allocated to tenants; and based on the frequency point resource, performing network access. That is, before the terminal device performs network access, that is, before the terminal device performs primary synchronization signal search, according to a fixed frequency band pre-negotiated between the tenant to which the terminal device belongs and the network device, determining a first frequency point list recording frequency point information that can be accessed by the terminal device at the current time, that is, the network device can broadcast the first frequency point list that can be used by the tenant to which the terminal device belongs on the fixed frequency band pre-negotiated between the terminal device and the network device, the terminal device can receive the first frequency point list on the fixed frequency band, that is, the terminal device can receive available frequency point resources on the fixed frequency band pre-negotiated, and perform primary synchronization signal search according to the available frequency point resources; obviously, the method and the device can conduct targeted search instead of blind search, so that the synchronization time is greatly reduced, and the synchronization efficiency is improved. Meanwhile, before the terminal equipment searches the main synchronous signal, one frequency point is selected from the frequency point information recorded in the effective frequency point list at the current moment to access, so that the problem of invalid access caused by the network access of the re-networking terminal is avoided.

Fig. 3 is a flow chart of an access method according to an embodiment of the present application, as shown in fig. 3, where the method is applied to the communication system 100 shown in fig. 1, and the method includes:

step 301, the network device broadcasts a frequency point list of each tenant in the set fixed frequency band.

Step 302, under the condition that the terminal equipment is awakened, the terminal equipment obtains a fixed frequency band set by the tenant to which the terminal equipment belongs and the network equipment.

Step 303, the terminal device obtains a first frequency point list of a tenant broadcasted by the network device received in the fixed frequency band.

Step 304, the terminal device obtains a first effective time period of the first frequency point list.

In the embodiment of the present application, the network device broadcasts the frequency point list of each tenant and the effective time period of the frequency point list of each tenant in the set fixed frequency band. That is, the effective period of the frequency point list of each tenant is independent from the frequency point list of each tenant. Here, the valid time periods of the frequency point list of each tenant may be presented in a form of a table, where each row in the table records a valid time period corresponding to one frequency point list.

In some embodiments, the list of points for each tenant includes a valid period of time for the list of points for each tenant.

In this embodiment of the present application, the first valid period includes a start time when the first frequency point list takes effect to an end time when the first frequency point list fails.

In the embodiment of the present application, the first frequency point list may be received in a last period of a plurality of broadcast periods; or may be received for the current one of a plurality of broadcast periods. The first frequency point list used by the subsequent terminal equipment when the network is accessed is determined by a first effective time period of the first frequency point list.

Step 305, the terminal device performs network access based on the frequency point resource and the first effective time period.

In the embodiment of the application, the access frequency point of the terminal equipment is determined based on the frequency point resource of the first frequency point list and the first effective time period of the first frequency point list, and network access is performed based on the access frequency point. That is, the terminal device only determines that the first frequency point list is within the validity period based on the first validity period, and can perform network access based on the frequency point resources of the first frequency point list.

It should be noted that, in this embodiment, the descriptions of the same steps and the same content as those in other embodiments may refer to the descriptions in other embodiments, and are not repeated here.

Fig. 4 is a flow chart of an access method according to an embodiment of the present application, as shown in fig. 4, where the method is applied to the communication system 100 shown in fig. 1, and the method includes:

step 401, the network device allocates a frequency point resource for the tenant b based on attribute information of the tenant b.

In the embodiment of the application, the attribute information includes a dynamic attribute and a static attribute.

Here, the dynamic attribute includes a prediction result of bandwidth demand of the tenant b and resource requests initiated in real time by terminals under the tenant b; the static attributes include a fixed bandwidth lease agreement entered into by the tenant. Wherein the bandwidth requirements include traffic channel requirements and access requirements. That is, the present application may allocate frequency point resources to tenant b based on a predetermined amount or real-time demand or a fixed protocol. Obviously, the frequency point resources are allocated to the tenant b, and the proper frequency point resources are obtained through prediction or calculation based on the user application, so that the resource utilization rate is higher and more flexible compared with a static satellite frequency point renting mode.

The prediction result of the bandwidth demand of the tenant b is based on the bandwidth demand of the tenant b in one period in the historical period, and the predicted bandwidth demand of the next period in the one period is obtained.

It should be noted that, when each tenant signs a lease protocol with a fixed bandwidth, the resource allocation module may also allocate a frequency point to the tenant according to the current frequency point utilization condition.

In the embodiment of the present application, the network device calculates the frequency point resources allocated to each tenant in each beam based on the attribute information of the tenant. Each beam comprises at least one fixed frequency band f ₀ ～f ₁ . Each fixed frequency band can correspond to a plurality of tenants.

Exemplary, beam A includes a fixed frequency band f ₀ ～f _n The fixed frequency band includes n frequency bins. Fig. 5 is a schematic diagram of a fixed frequency point leasing manner and a dynamic frequency point leasing manner according to an embodiment of the present application. As shown in fig. 5, in the fixed-frequency renting mode, bandwidths and frequency used by tenant 1, tenant 2 and tenant 3 are fixed, and the frequency dynamic renting mode is implementedThe bandwidths and the frequency points used by the tenants 1, 2 and 3 can be dynamically adjusted according to the actual demands of the tenants; the frequency points used by the same tenant in different broadcasting periods can be dynamically adjusted, namely, the frequency points used by tenant 1, tenant 2 and tenant 3 in the first period are different from the frequency points used by tenant 1, tenant 2 and tenant 3 in the second period.

In this embodiment of the present application, if the attribute information of the tenant b is a prediction result of the bandwidth demand of the tenant b, the network device allocates a frequency point resource to the tenant b based on the attribute information of the tenant b in step 401, which may be implemented by:

And A1, obtaining a trained time sequence prediction model.

And A2, obtaining the access quantity of the terminals under the tenant b and the bandwidth resources occupied by the terminals under the tenant b in a period and in a fixed frequency band.

And step A3, inputting the access quantity and the occupied bandwidth resources into a trained time sequence prediction model to obtain the bandwidth demand of the lessor b in the next period.

And step A4, allocating frequency point resources for the tenant b based on the bandwidth demand of the tenant b in the next period.

In the embodiment of the present application, the demand of each tenant in each satellite wave position on satellite bandwidth is similar to the resource utilization rate of a physical resource block (Physical Resource Block, PRB) of a cell, and the uncertainty, the direct correlation with significant activities, event arrangement and the autocorrelation (periodic fluctuation in units of days, zhou Shenzhi months and quarters) are presented. The time series model is:

y(t)＝g(t)+s(t)+h(t)+ε _t (1)

Wherein g (t) is a trend model modeling the aperiodic variations of the time series values; s (t) is a seasonal model, representing periodicity (per unitDay or week) effect of change on time series values; h (t) is a holiday model, representing the effect of a special case on time series values; epsilon _t Is a noisy part of the time series, representing unpredictable random fluctuations.

In this embodiment of the present application, a network device, for example, a gateway station, periodically records satellite bandwidth utilization conditions of each tenant in each wave bit through a traffic billing module, that is, when time is t, in tenant b of wave bit x, bandwidth resources are used to obtain a historical dataset BW _b,x ＝(BW _b,x,1 ，BW _b,x,2 ……BW _b,x,t ). When the periodic recording time of the gateway station is t, obtaining a historical data set U under the condition of the number of access users of the wave position x tenant b _b,x ＝(U _b,x,1 ，U _b,x,2 ……U _b,x,t )。

Here, the gateway station divides the counted historical data set into two parts through the resource allocation module: the last Y days of data were used as the test set, the remainder as the training set. One tenant training set can be selected to be input into the time sequence model for training, and each component of the time sequence model is fitted. Since bandwidth utilization behavior of individual tenants is substantially uniform, other tenants can multiplex the model in order to reduce computational complexity.

In the embodiment of the application, the gateway station uses the resource allocation module to send the historical data set BW _b,x Inputting the fitted time sequence model, and predicting and obtaining satellite bandwidth utilization condition BW 'of each tenant in each wave position in a future period' _b,x ＝(BW _b,x,t+1 ，BW _b,x,t+2 ……BW _b,x,t+t′ ). Will history data set U _b,x Inputting the fitted time sequence model, and predicting to obtain access user condition U 'of future period' _b,x ＝(U _b,x,t+1 ，U _b,x,t+2 ……U _b,x,t+t′ )。

In some embodiments, the gateway station passes BW' _b,x And U' _p,x Obtaining frequency point resource F 'of future time resource allocation module for wave position x tenant b' _b,x ：

F′ _b,x MAX (traffic channel demand, access channel demand) +f _{Allowance of} (2)

Wherein the traffic channel demand is defined by the predicted bandwidth utilization BW' _b,x Determining that the access channel demand is determined by the number of access users U' _b,x Determination, F _{Allowance of} The frequency point resource allowance is increased for ensuring the sufficient allocation of the frequency point resources.

In the embodiment of the application, the frequency point resource set F 'is set according to a future period of time' _b,x ＝(F′ _b,x,t+1 ,F′ _b,x,t+2 ……F′ _b,x,t+t′ ) If the frequency point resource demand of the latest time M is unchanged/does not change much, the resource allocation module may set the effective time of the frequency point allocation scheme to M. The degree of change of the frequency point resource demand can be set by each tenant or by a gateway station, which is not particularly limited in the application.

In step 402, in one of a plurality of broadcast periods, the network device obtains information about use of frequency point resources of the beam of the satellite wave bit x by the tenant b in the satellite wave bit x and the number of frequency point resources allocated to the tenant b.

Wherein x and B are positive integers, B is more than or equal to 1 and less than or equal to B, and B is the total number of each tenant.

In the embodiment of the present application, the usage information of the frequency point resource includes information of each tenant occupying the frequency point resource.

Step 403, the network device obtains frequency point information allocated to the tenant b in a next period of the period based on the usage information of the frequency point resources and the frequency point resource number.

In the embodiment of the application, the frequency points which are occupied by the terminal and the frequency points which are not occupied by the terminal in one period can be determined through the use information of the frequency point resources; and determining the number of terminals allowed to be accessed in the tenant b through the frequency point resource number, and further, obtaining frequency point information allocated to the tenant b in the next period of one period according to the use information of the frequency point resource and the frequency point resource number.

Step 404, the network device generates a frequency point list of the tenant b based on the frequency point information allocated to the tenant b in the next period.

In this embodiment of the present application, the frequency point list of the tenant b includes the tenant identifier of the tenant b, the frequency point information allocated to the tenant b, and the valid time of the frequency point information allocated to the tenant b. Here, the frequency point information allocated to the tenant b in the frequency point list has effective time, and only in the effective time, the frequency point information allocated to the tenant b in the frequency point list can be used; if the frequency point information allocated to the tenant b in the frequency point list used by the terminal equipment is not in the effective time, the problem that the access is impossible can be caused; i.e. the frequency bin list in the present application is time-efficient.

It should be noted that the valid time may be a specific time period, for example, the frequency point information allocated to the tenant b is valid only from 2022, 7, 9, to 2022, 7, 19; alternatively, the effective time is a relative time period, for example, the effective time period of the frequency point information allocated to the tenant b is 1 day; this application is not particularly limited.

Step 405, the network device broadcasts a frequency point list of each tenant in the set fixed frequency band.

Wherein each tenant comprises tenant b; the frequency point list of each tenant comprises a first frequency point list of the tenant to which the terminal equipment belongs; the first frequency point list comprises frequency point resources allocated to the tenant to which the terminal equipment belongs.

Illustratively, the gateway station is at satellite beam f ₀ ～f ₁ In the fixed frequency band, the currently allocated frequency point List list_F is periodically broadcast to the wave bit x _x,m . Table 1 is a frequency bin list provided in the present application. The frequency point list comprises tenant identifications, frequency point resources distributed to the tenants and effective time of the frequency point resources.

TABLE 1

Wherein, the fixed frequency band f ₀ ～f ₁ Including a plurality of frequency bins, for example: frequency point _1，1 Frequency point _k，1 The method comprises the steps of carrying out a first treatment on the surface of the k is a positive integer greater than 1.

Step 406, in the case that the terminal device is awakened, the terminal device obtains a second frequency point list that is used by the terminal device last time before being awakened.

In the embodiment of the application, when the terminal equipment is in one of the following states, the terminal equipment is determined to be awakened;

starting up the terminal equipment;

the terminal equipment is switched from a power saving state to an activated state;

the terminal device switches from the enhanced discontinuous reception state to the continuous reception state.

In the embodiment of the present application, when the terminal device is in a Power Save Mode (PSM), an enhanced discontinuous reception (Extended Discontinuous Reception, eDRX) state, and a DRX state, data can be received only in a time when the receiver is turned on, and downlink data cannot be received in a time when the receiver is turned off. It should be noted that when the terminal device is in PSM, eDRX and DRX states, the frequency of turning on the receiver is low, for example, the receiver is turned on once a few days, that is, when the terminal device is in PSM, eDRX and DRX states, the frequency of receiving the signal by the receiver of the terminal device is considered to be greater than or equal to the reception frequency threshold.

In some embodiments, in PSM mode, after the communication module of the terminal device enters an idle state for a period of time, the receiving and transmitting of signals and the related functions of the access layer are turned off. The terminal equipment enters the local shutdown state, and the gateway equipment cannot access the terminal, namely, cannot be called. In the DRX mode, the terminal device stops listening to the physical downlink control channel (Physical Downlink Control Channel, PDCCH) for a certain period of time, and periodically enters a sleep state. eDRX mode is a functional extension to further enhance power saving based on DRX mode.

In this embodiment, the terminal device powering on refers to that the receiver of the terminal device is switched from a continuous off state to a continuous on state.

Step 407, the terminal device obtains a second effective time period of the second frequency point list.

In this embodiment of the present application, each frequency point list further includes an effective time period of a frequency point resource allocated to a tenant to which the terminal device belongs.

In this embodiment, the obtaining, by the terminal device in step 407, the second valid period of the second frequency point list may also be implemented by the following steps: the terminal equipment determines the effective time of the second frequency point list; the terminal equipment acquires a starting time point for receiving the second frequency point list, and acquires a second effective time period of the second frequency point list according to the starting time point and the effective time.

In this embodiment, the effective time periods of the frequency point lists of different tenants may be different or the same.

In this embodiment of the present application, the valid time periods of the frequency point lists received by the same tenant in different broadcast periods may be different, or may be the same.

Step 408, if the system time of the terminal device exceeds the second effective period, the terminal device reads the fixed frequency band stored in the terminal device.

In this embodiment of the present application, if the system time of the terminal exceeds the time range of the second effective time period of the second frequency point list, the fixed frequency band is read from the inside of the terminal device, and the fixed frequency band f is used ₀ ～f ₁ And (5) monitoring broadcast information. If the system time of the terminal does not exceed the time range of the second effective time period of the second frequency point list, the terminal equipment directly uses the frequency point resources of the tenant in the second frequency point list to perform network access. Obvious. According to the method and the device, the frequency point list of the previous period can be directly used under the condition that the frequency point list of the previous period is still in the effective period, the step of receiving the frequency point list of the broadcast of the current period is omitted, the occupation of terminal equipment resources is reduced, and the utilization rate of the frequency point list is improved.

In this embodiment, the reading of the fixed frequency band stored in the terminal device in step 408 may be implemented through steps B1 to B2, or may be implemented through step B3:

And B1, under the condition that the terminal equipment is covered by the different-frequency beam, the terminal equipment obtains the terminal position of the terminal equipment, ephemeris information sent by the satellite and a coverage area of the beam covering the terminal equipment.

And B2, determining an actual beam covering the terminal equipment based on the terminal position, the ephemeris information and the coverage area, and reading a fixed frequency band corresponding to the actual beam stored in the terminal equipment.

In the embodiment of the application, for the terminal equipment covered by the different-frequency beam, the actual beam covering the terminal equipment is determined according to the terminal position of the terminal equipment, ephemeris information sent by the satellite and the coverage area of the beam covering the terminal equipment, and the fixed frequency band corresponding to the actual beam is read from a plurality of frequency bands stored in the terminal equipment.

And B3, under the condition that the terminal equipment is covered by the same-frequency beam, reading the fixed frequency band corresponding to the same-frequency beam stored in the terminal equipment.

In the embodiment of the present application, if the terminal device is always in the scene covered by the same frequency beam, the terminal device will only store one fixed frequency band. If the satellite communication system has a plurality of different frequency beams, each different frequency beam should correspond to a different fixed frequency band information f _n ～f _n+1 If the terminal equipment is in the coverage of the different-frequency beam, the terminal can calculate the beam currently covering the terminal equipment according to the terminal position, the ephemeris information and the beam coverage, and further read the working frequency band of the antenna generating the beam covering the terminal equipment as the fixed frequency band corresponding to the terminal equipment.

The ephemeris information is also called as an ephemeris table, and refers to a star orbit parameter table, that is, list data is used to indicate the preset position of a certain star at regular intervals or the preset position of a certain artificial satellite at regular intervals.

Step 409, the terminal device obtains a first frequency point list of the tenant broadcasted by the network device received in the fixed frequency band.

In the embodiment of the application, the terminal device may obtain the currently allocated frequency point List list_f by broadcasting _x,m The method comprises the steps of carrying out a first treatment on the surface of the Obviously, the terminal equipment can quickly acquire the frequency point information distributed to the affiliated tenant, so that the long-time main synchronous signal search brought by blind search of the terminal equipment is reduced, and the network access process is quickened.

In this embodiment of the present application, if the system time of the terminal does not exceed the valid time of the second frequency point list, the first frequency point list obtained in step 409 is the last second frequency point list used by the terminal device before being awakened.

Step 410, the terminal device randomly selects a frequency point from the frequency point resources as an access frequency point of the terminal device.

In the embodiment of the present application, after obtaining the first frequency point list currently allocated to the affiliated tenant, the terminal device selects one of the frequency points as the access frequency point with equal probability instead of according to the list order.

The probability J of one frequency point in the frequency point resources allocated to the tenant of the terminal equipment in the first frequency point list is:

and B is the total number of frequency point resources of the tenant to which the terminal equipment belongs.

Step 411, the terminal device performs network access at the access frequency point.

In the embodiment of the application, the terminal equipment detects the main synchronous signal on the access frequency point to obtain the information of the target cell associated with the terminal equipment, and the cell searching process is realized.

In the embodiment of the application, the network device directly informs the terminal device of the frequency point information distributed by each tenant, the terminal device solves the frequency point information of the tenant to which the terminal device belongs through the tenant identification, and one frequency point is randomly accessed, so that the frequency points of other tenants are prevented from being detected, and invalid access is avoided.

in step 601, the network device encrypts the frequency point list of each tenant based on the tenant identifier and/or the code of the tenant identifier, to obtain an encrypted frequency point list.

In the embodiment of the application, in order to improve the security of the frequency point List, the frequency point List list_F of each tenant _p,x,m The frequency point information of the tenant has respective encryption modes, and only the terminal of the tenant can know the encryption modes. That is, the network device may determine an encryption policy of the frequency point list corresponding to different tenants according to the tenant identifier, for example, the code of the land operator public land mobile network (Public Land Mobile Network, PLMN) identifier and/or the tenant identifier, and encrypt the frequency point list according to the encryption policy, to obtain an encrypted frequency point resource and an encrypted effective time period. Here, the code of the tenant identifier is obtained by using some coding means for the tenant identifier, and thus, there is a mapping relationship between the code of the tenant identifier and the tenant identifier.

It should be noted that, the encryption policies of different tenants are different, and the terminal device can only decrypt the frequency point information corresponding to the tenant to which the terminal device belongs, and cannot know the frequency point information of other tenants. Therefore, the terminal equipment under the same tenant can be accurately decrypted, and the frequency point can be prevented from being occupied by terminals under other tenants.

In some embodiments, the encryption policies adopted for the same tenant may also be different, for example, according to different user levels or wake-up scenarios of terminal devices under the same tenant, different layers of encryption policies are adopted for frequency points available in different levels or wake-up scenarios.

For example, for tenant a, the tenant a includes a terminal 1 with a first level of user level and a terminal 2 with a second level of user level, where the user level of the terminal 1 is greater than the user level of the terminal 2, then only one layer of encryption algorithm is adopted for the frequency point available to the terminal 1, and one layer of encryption algorithm is added on the basis of encryption of the terminal 1 for the frequency point available to the terminal 2.

In some embodiments, the network device encrypts the frequency point list directly based on the tenant identification and/or the encoding of the tenant identification, to obtain an encrypted frequency point resource and an encrypted effective time period. For example, the tenant identifier is 123, and the code of the tenant identifier is ABC, where the frequency point list may be encrypted by using 123 as an encryption key; or the ABC is used as an encryption key to encrypt the frequency point list; or the 123ABC is used as an encryption key to encrypt the frequency point list.

Step 602, the network device broadcasts each encrypted frequency point list in the set fixed frequency band.

In the embodiment of the application, the network device broadcasts the encrypted frequency point list corresponding to each tenant in the set fixed frequency band.

In this embodiment of the present application, each encrypted frequency point list includes an encrypted frequency point resource, or each encrypted frequency point list includes an encrypted frequency point resource and an encrypted effective time period.

Step 603, the terminal device obtains a fixed frequency band set by the tenant and the network device to which the terminal device belongs when the terminal device is awakened.

Step 604, the terminal device obtains an encrypted first frequency point list of the tenant broadcasted by the network device received in the fixed frequency band based on the tenant identifier of the tenant and/or decoding of the tenant identifier.

Step 605, the terminal device obtains a decryption key of the first frequency point list.

In the embodiment of the application, the decryption key is pre-stored in the terminal equipment and can be associated with a user level or a wake-up scene.

Step 606, the terminal device decrypts the encrypted first frequency point list based on the decryption key, and obtains a decrypted first frequency point list.

The decrypted first frequency point list comprises frequency point resources distributed to the tenant of the terminal equipment.

In the embodiment of the application, the terminal equipment obtains the list_F of the frequency points through tenant identification or decoding based on tenant identification _x,p,m Determining a decryption method through a decryption key prestored in the terminal equipment; and solving the frequency point information and the effective time period corresponding to the tenant of the terminal equipment based on the decryption method.

Here, the decoding of the tenant identity is obtained by using some decoding means for the encrypted tenant identity, and therefore, there is a mapping relationship between the decoding of the tenant identity and the tenant identity.

Step 607, the terminal device performs network access based on the frequency point resource.

In the embodiment of the application, the frequency point list allocated by the network equipment to each tenant has respective encryption modes, and the terminal subordinate to the tenant adopts the corresponding decryption mode to decrypt the frequency point list and then uses the frequency point to carry out network access, so that the security of the frequency point leased by each tenant can be improved, and invalid access caused by mixed use of the frequency point of each tenant can be avoided.

In step 703, the network device 120 determines, through the resource allocation module, which frequency points are allocated to the tenant b of the current beam in the next period according to the frequency point utilization condition of the current beam, and generates a frequency point list.

Step 704, the network device 120 sends the frequency point list to the communication device 130.

Step 705, the communication device 130 periodically broadcasts a frequency bin list to each band in the fixed frequency band.

Step 706, in the case that the terminal device 110 is awakened, the terminal device 110 determines whether the frequency point list used last time before being awakened is invalid; if not, step 707 is performed, otherwise step 708 is performed.
