Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a random access method, user equipment, and network side equipment. Background Art

[0002] The satellite beam hopping communication system consists of a ground gateway, a satellite (beam pointing hopping) and a user equipment (User Equipment, UE). The ground gateway is such as a base station (NR Node B, GNB). The low-orbit satellite communication system uses beam hopping technology to increase system capacity, reduce interference and improve configuration flexibility. The hopping beam hops within the coverage area of ​​the satellite cell at a certain period. The pointing direction of each hopping beam will change. The single stay time of the beam in each spatial direction is called the dwell time; the beam hopping visits all candidate directions is called a hopping cycle. Hopping beams are divided into control hopping beams (referred to as control beams) and service hopping beams (referred to as service beams) according to their functions.

[0003] In existing technologies, when control beams are configured separately from service beams, control beams are typically used for interactive signaling, including uplink and downlink synchronization, random access, and resource scheduling. Due to the bursty nature of control beam signaling and the polling method used during hopping, the control beam is often underloaded. This results in wasted resources when satellite power is severely limited. Summary of the Invention

[0204] To make the technical problems, technical solutions, and advantages to be solved by the present invention more apparent, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and brevity, descriptions of known functions and configurations have been omitted.

[0205] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment.

For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0209] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0210] When describing the embodiments of the present invention, some concepts used in the following description are first explained.

[0211] Ground 5G beam scanning system: The 5G NR cellular mobile communication system uses beam scanning technology. Through beam management, network resources can be more effectively utilized to provide services to UEs within the cell. The principle of NR beam scanning is as follows Figure 1 As shown in the figure, the current 5G NR standard beam management solution does not distinguish between control beams and service beams; both types of data are transmitted through the same beam. This has no impact on the random access process of user equipment.

[0212] Satellite beam-hopping communication system: Taking low earth orbit satellite (LEO) as an example, the low earth orbit satellite beam-hopping communication system is as follows: Figure 2 As shown, the hopping beam includes a control beam and a service beam. The control beam generally hops in a polling manner, and the service beam hops according to service requirements or a Quality of Service (QoS) guarantee solution.

[0213] Depend on Figure 1 and Figure 2 As can be seen, the service beam and control beam have different functions, different transmission contents, and different hopping periods. The control beam mainly transmits control signaling, while the service beam mainly transmits user data.

[0214] Specifically, embodiments of the present invention provide a random access method, user equipment, and network-side equipment to solve the problem of resource waste caused by existing random access methods.

[0215] like Figure 3 As shown, an embodiment of the present invention provides a random access method, which is applied to a user equipment and specifically includes the following steps:

[0216] Step 301: The user equipment sends a service beam resource request message required for random access to a network side device in the control beam of the hopping beam.

[0217] The user equipment obtains downlink synchronization in the control beam and initiates a random access service beam resource application in the control beam, that is, sends a service beam resource request message to the network side device in the control beam to apply for service beam resources.

[0218] Step 302: The user equipment receives resource configuration information sent by the network side device in the control beam.

[0219] After receiving the service beam resource request message sent by the user equipment, the network-side device schedules a service beam for the user equipment to provide coverage, thereby supporting random access by the user equipment. The network-side device may determine resource configuration information for the service beam based on the service beam resource request message and the current resource utilization status, and send the resource configuration information to the user equipment in the control beam. The network-side device schedules the service beam to provide random access service for the user equipment.

[0220] Step 303: The user equipment initiates a random access process in the service beam of the hopping beam according to the resource configuration information.

[0221] The user equipment can obtain relevant information such as the hopping period of the service beam configured by the network side device based on the resource configuration information, thereby initiating a random access process in the service beam. Wherein, the user equipment initiating a random access process in the service beam means: performing random access in the service beam.

[0222] In this embodiment of the present invention, a user device applies for service beam resources required for random access in the control beam of a hopping beam, obtains service beam resource configuration information sent by a network device in the control beam, and initiates random access in the service beam based on the resource configuration information. This embodiment simplifies control beam design, reduces control beam power, bandwidth, and other configuration requirements, and increases service beam power configuration, thereby improving resource utilization in the communication system.

[0223] Specifically, the service beam resource request message may include: a detection sequence of the user equipment;

[0224] or

[0225] The service beam resource request message may include: a detection sequence of the user equipment and location information of the user equipment.

[0226] In this embodiment, the service beam resource request message sent by the user equipment to the network-side device may include the detection sequence of the user equipment, or may include both the detection sequence of the user equipment and the location information of the user equipment. If the service beam resource request message does not include the location information of the user equipment, the location information of the user equipment may be implicitly indicated by the detection sequence of the user equipment.

[0227] The detection sequence may include one of the following:

[0228] a) First preamble sequence: The first preamble sequence may be a preamble sequence (ie, preamble sequence) in an existing protocol standard.

[0229] b) a second preamble sequence having a length greater than or equal to the first value; the first value can be set as required. Preferably, the first value is greater than the length of the preamble sequence in the existing protocol standard, that is, a longer preamble sequence is designed as a detection sequence, such as a pseudo-random (Pseudo-Noise, PN) sequence or a ZC (Zadoff-chu) sequence with a length of 2048 or 4096. Each user equipment is assigned a detection sequence as a unique identifier of the user equipment, which can improve the detection probability under low signal-to-noise ratio.

[0230] c) A third preamble sequence that has been authorized for scrambling and has a length greater than or equal to the first value. Using a special long PN code that has been authorized for scrambling as a detection sequence, each special user device is assigned a detection sequence that uniquely identifies the user device. Upon receiving this type of detection sequence, the network device can prioritize resource allocation and ensure access to services for special users. This can reduce false detection rates, improve the detection rate of special users, and prevent malicious resource request signals.

[0231] Specifically, the location information may include at least one of the following:

[0232] 1) The latitude, longitude and elevation information of the user equipment on the ground;

[0233] 2) User equipment beam position information. The user equipment location information may be relative position information of the user equipment in the current satellite cell, such as beam position information. A beam position refers to the ground position covered by each hopping beam, and the coverage area of ​​each satellite may consist of multiple beam positions.

[0234] Optionally, when the service beam resource request message does not include the location information of the user equipment, the location information of the user equipment may be indicated by a detection sequence in the service beam resource request message, or the RO time-frequency resource may implicitly indicate the location information of the user equipment. For example, the timing of sending the service beam resource request message indicates the location of the user equipment. When the service beam resource request message includes a detection sequence and the location information of the user equipment, the location information of the user equipment may also be implicitly indicated by the detection sequence, or implicitly indicated by the RO time-frequency resource. Specifically, the service beam resource request message implicitly indicates the location information of the user equipment.

[0235] The manner in which the service beam resource request message implicitly indicates the location information of the user equipment includes one of the following:

[0236] a) The detection sequence corresponds to the waveband of the user equipment; for example, the detection sequence of the user equipment corresponds to the waveband number of the waveband of the user equipment. That is, the detection sequence corresponds to the waveband of the user equipment, and the location information of the user equipment can be obtained based on the detection sequence and the corresponding relationship.

[0237] b) The set of detection sequences corresponds to the waveband location of the user equipment; for example, the set of detection sequences for the user equipment corresponds to the waveband location number of the waveband location of the user equipment, that is, one waveband location corresponds to one set of detection sequences. That is, the set of detection sequences corresponds to the waveband location of the user equipment, and the location information of the user equipment can be obtained based on the set of detection sequences and the corresponding relationship.

[0238] c) The detection sequence and random access channel timing (RO) time-frequency resource each correspond to the beam position of the user equipment. For example, the beam position number of the user equipment corresponds to a detection sequence and an RO time-frequency resource. That is, the detection sequence and RO time-frequency resource each correspond to the beam position of the user equipment. The user equipment's location information can be obtained based on the detection sequence and the timing of sending the service beam resource request message.

[0239] This embodiment implicitly includes the location information of the user equipment in the service beam resource request message. For example, the wave position of the user equipment can be pre-assigned to the preamble sequence, the time-frequency resource position of the RO, or different detection sequence sets in the protocol. When the network side device detects the service beam resource, it can detect the location of the user equipment.

[0240] In this embodiment, to reduce the uplink overhead when a user device requests service beam resources within a control beam, a detection sequence can be used to implicitly carry the user device's location information. The user device's beam position information within the satellite's coverage area (a beam position refers to the area covered by each satellite beam hop) is associated with the detection sequence. After the network-side device detects the user device's uplink detection sequence, it can infer the user device's beam position information within the satellite's coverage area. Specifically, the satellite coverage area must be pre-divided into a large number of beam positions. This division can be arranged in a rectangular, square, or cellular layered arrangement. The number of beams depends on the satellite cell range and the coverage range of a single satellite beam. Adjacent beam positions will overlap to achieve complete coverage under the satellite. During system configuration, the satellite's beam positions are pre-numbered. For example, if a satellite is divided into 200 beam positions, the 200 beam positions are numbered according to a certain rule, resulting in beam position numbers 0, 1, 2, ..., 199.

[0241] The network-side equipment can pre-assign satellite beam position numbers to available detection sequences. This can be done by mapping one beam position to one detection sequence, one beam position to a group of detection sequences, or one beam position to one detection sequence and one RO time-frequency resource. Ultimately, a one-to-one mapping between beam positions and detection sequences, or between beam positions, detection sequences, and RO resources, is achieved. This allows the network-side equipment to identify the beam position of the user equipment based on the detection sequence and the timing of random access channel transmission.

[0242] Optionally, the location information of the user equipment includes: wave position information of the user equipment;

[0243] Before sending a service beam resource request message required for random access to the network side device, the method further includes:

[0244] Acquire the wave position information of the user equipment; determine the detection sequence corresponding to the wave position information according to the correspondence between the wave position information and the detection sequence;

[0245] The correspondence between the wave position information and the detection sequence is sent by the network side device or obtained by calculation by the user equipment.

[0246] In this embodiment, the service beam resource request message sent by the user equipment to the network side device may include the user equipment's wave position information, that is, the service beam resource request message includes the user equipment's detection sequence and the user equipment's wave position information. Before sending the service beam resource request message to the network side device, the user equipment needs to obtain its own wave position information. According to the correspondence between the wave position information and the detection sequence, the detection sequence corresponding to the wave position can be obtained. The correspondence between the wave position information and the detection sequence can be established by the network side device in advance by establishing a correspondence between the satellite wave position number and the available detection sequence, and sending the correspondence to the user equipment; or, the correspondence between the wave position information and the detection sequence can be pre-configured in the user equipment, which can be set by the network side device through a standard protocol. The user equipment is pre-configured with a wave position allocation strategy, and can determine the location information according to the wave position division rule, and then search a pre-set table based on the wave position information to obtain the corresponding detection sequence.

[0247] Specifically, obtaining the wave position information of the user equipment may include:

[0248] Determine the wave position sequence number of the wave position where the user equipment is located according to the global navigation satellite system;

[0249] or

[0250] The wave position sequence number of the wave position where the user equipment is located is obtained from the downlink broadcast signal in the control beam.

[0251] In this embodiment, a first method for a user device to obtain its own beam position information may be: the user device may obtain its own position based on the Global Navigation Satellite System (GNSS), obtain the position of the satellite based on the ephemeris, and pre-configure the beam position allocation policy for the user device so that it can obtain the beam position sequence number of the current satellite it is located at. Another method is for the user device to obtain the current beam position sequence number from the downlink broadcast signal in the control beam. Specifically, the network-side device transmits a downlink broadcast signal in the control beam, and the control beam transmits different beam position sequence number information in the broadcast signal on each beam position.

[0252] In this embodiment, when the user equipment controls the beam to initiate a service beam resource application, it first needs to obtain its own wave position information, then determine the corresponding detection sequence based on the wave position information, and finally carry the detection sequence when sending a service beam resource request message to the network side device.

[0253] Among them, the network side device can broadcast the wave position information and the preamble information available for the wave position in the control beam. After the user equipment obtains the wave position information, it selects the corresponding preamble to initiate a service beam resource application; or, the network side does not broadcast the wave position information, the user equipment knows the wave position division rule, the user equipment can obtain its own location information, calculate the current wave position sequence number based on the location information and the wave position division rule, and select the preamble to apply for service beam resources. Optionally, when the network side device does not broadcast the wave position information and the user equipment does not know the wave position division rule, the user equipment can obtain its own location information and carry the location information when sending a service beam resource request message to the network side device. The network side device determines the wave position information of the user equipment based on the location information of the user equipment and can carry the wave position information of the user equipment when sending a random reception response RAR message to the user equipment in the random access process.

[0254] Specifically, after the network side device receives the service beam resource request message sent by the user equipment, it configures resource configuration information of the service beam for the user equipment. The resource configuration information may include:

[0255] A) Resource Request Response Message: The resource request response in the resource request response message, for example, "0" indicates that no service beam resources can be scheduled.

[0256] In a case where the resource request response message indicates that no service beam resources can be scheduled, the method further includes: repeatedly sending the service beam resource request message according to a predetermined period.

[0257] In this embodiment, when the resource configuration information is "0", the user equipment can wait for a period of time and then initiate an access application again (i.e., send the service beam resource request message again). The waiting time can be configured according to the access period of the control beam and configured as a positive integer multiple of the control beam access period.

[0258] B) Service beam scheduling information. This information may include status information for the assigned service beam, including the access time, frequency band configuration, and dwell time of the service beam. For example, the resource configuration information may include the service beam index. The correspondence between the service beam index and the frequency band allocation may be pre-specified in the protocol.

[0259] It should be noted that the resource configuration information may also include other required information; or, the resource configuration information may include information bits reserved for subsequent function expansion, or include subsequent access mode selection indication, etc.

[0260] After the user equipment receives the resource configuration information of the service beam sent by the network side device, the random access process is initiated in the service beam according to the resource configuration information. Specifically, the random access process is initiated in the service beam of the hopping beam according to the resource configuration information, which may include:

[0261] The random access method of the random access process is determined according to the configuration of the network side device or customization; according to the random access method, the random access process is performed in the service beam; wherein, when the random access method is configured by the network side device, the resource configuration information includes indication information of the random access method.

[0262] The random access mode may include a 4-step access mode and a 2-step access mode. The random access mode may be configured by a network-side device. For example, the network-side device configures an access mode for a user device, which may be carried in the resource configuration information, informing the user device to select one of the 4-step or 2-step modes to access the service beam, or to first perform 2-step access and then 4-step access, or first perform 4-step access and then 2-step access, etc.

[0263] The random access method can be customized by the user equipment, that is, the user equipment independently selects it. In this case, the user equipment independently selects the 2-step access method or the 4-step access method according to the access method supported by the network side device, or first performs the 2-step access and then the 4-step access method, or first performs the 4-step access and then the 2-step access, etc.

[0264] As an optional embodiment, the specific steps of the four-step access method: performing a random access process in the service beam according to the random access method may include:

[0265] 1) sending a first message to the network-side device in the service beam, where the first message includes a physical random access channel (PRACH) signal;

[0266] 2) receiving, in the service beam, random receive response (RAR) information sent by the network-side device;

[0267] 3) sending a second message to the network side device in the service beam, where the second message includes: a user equipment identifier and a radio resource control (RRC) connection request;

[0268] 4) Receive random access success feedback information sent by the network side device in the service beam to resolve the contention.

[0269] Specifically, in a case where the service beam resource request message does not include the beam position information of the user equipment, the RAR information includes the beam position information of the user equipment.

[0270] In the embodiment of the present invention, the wave position information of the user equipment may be obtained in the following ways:

[0271] Method 1: The network-side device broadcasts the information of the beam position and the available preamble information of the beam position in the control beam. After obtaining the beam position information, the user equipment selects the preamble to initiate a service beam resource application.

[0272] Method 2: The network side device does not broadcast the beam position information, but the user device knows the beam position allocation rules. The user device can obtain positioning information, calculate the current beam position sequence based on the positioning information and the beam position allocation rules, and select the preamble to apply for service beam resources.

[0273] Method 3: The network side device does not broadcast the wave position information, and the user equipment does not know the wave position division rules. The user equipment can obtain positioning information. When the user equipment initiates a service beam resource application, it carries the location information. The network side device can feedback the wave position information in the RAR of the above random access process.

[0274] As another optional embodiment, the specific steps of the two-step access method: performing a random access process according to the random access method may include:

[0275] 1) Sending a third message to the network side device in the service beam, wherein the third message includes a PRACH signal, a user equipment identifier, and an RRC connection request; the third message may also include other required information.

[0276] 2) Receive random access success feedback information sent by the network side device in the service beam.

[0277] The random access process of the embodiment of the present application is described below through specific examples.

[0278] like Figure 4 As shown, it includes: step 41, the user equipment obtains downlink synchronization in the control beam;

[0279] Step 42: The user equipment initiates a random access request for the service beam resources required in the control beam, Msg1 (i.e., the service beam resource request message). The Msg1 message can be sent multiple times.

[0280] Step 43: The user equipment receives the resource request feedback Msg2 (i.e., the resource configuration information) in the control beam. If Msg2 is not received, the user equipment repeatedly sends Msg1.

[0281] Step 44: The user equipment initiates a random access process in the service beam according to the content of Msg2 (supporting 4-step or 2-step random access).

[0282] Step 45: The user equipment completes random access.

[0283] For the random access method, the execution process of the user equipment and the network side device is as follows: Figure 5 As shown, including:

[0284] Step 51: The user equipment obtains downlink synchronization in the control beam;

[0285] Step 52: The user equipment applies for the service beam resources required for random access in the control beam, that is, sends a service beam resource request message Msg1;

[0286] Step 53: The network-side device determines the resource configuration of the service beam based on Msg1 and feeds back the resource configuration information Msg2 in the control beam. The user equipment then receives the resource configuration information Msg2 about the service beam in the control beam.

[0287] In step 54, the network device schedules a service beam for the user equipment to provide coverage (the service beam is directed toward the user equipment). The user equipment initiates a random access procedure in the service beam based on the content of Msg2. The specific random access procedure can be a four-step access method or a two-step access method, which is not described here.

[0288] In this embodiment of the present invention, a user device applies for service beam resources required for random access in the control beam of a hopping beam, obtains service beam resource configuration information sent by a network device in the control beam, and initiates random access in the service beam based on the resource configuration information. This embodiment simplifies control beam design, reduces control beam signaling interaction requirements, and can lower control beam power, bandwidth, and other configurations, saving resource overhead. It can also increase the power configuration of the service beam, thereby improving resource utilization in the communication system.

[0289] It should be noted that the random access method provided in the embodiment of the present invention is not only applicable to the LEO communication system, but also to the geosynchronous earth orbit satellite (GEO) communication system and the medium earth orbit satellite (MEO) communication system, which will not be described in detail here.

[0290] It should be noted that the user equipment involved in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. The user equipment is, for example, a terminal device, wherein the wireless terminal device can communicate with one or more core networks (CNs) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present application.

[0291] It is worth noting that the network side device involved in the embodiments of the present application can be a satellite communication device, such as a base station based on satellite communication, wherein the satellite and the base station can be set as an integrated whole, or the satellite and the base station can be set separately. It should be noted that the network side device can also be an unmanned high altitude platform (HAPS) communication device, such as a drone; in addition, the network side device can also be a ground communication device. When the network side device is a ground communication device, it is necessary to ensure that a hopping beam method is used during beam scanning, that is, the control beam and the service beam are separated.

[0292] like Figure 6 As shown, an embodiment of the present invention further provides a random access method, which is applied to a network side device, including:

[0293] Step 601: A network-side device receives a service beam resource request message sent by a user equipment in a control beam of a hopping beam.

[0294] The user equipment obtains downlink synchronization in the control beam, and initiates a service beam resource application required for random access in the control beam of the hopping beam, that is, sends a service beam resource request message to the network side device in the control beam to apply for service beam resources, and the network side device receives the service beam resource request message sent by the user equipment in the control beam.

[0295] Step 602: The network-side device determines resource configuration information according to the service beam resource request message and resource utilization status.

[0296] Step 603: The network side device sends the resource configuration information to the user equipment in the control beam.

[0297] After receiving the service beam resource request message sent by the user equipment, the network device schedules a service beam for the user equipment to provide coverage, thereby supporting random access by the user equipment. The network device may determine resource configuration information for the service beam based on the service beam resource request message and the current resource utilization status, and send the resource configuration information to the user equipment in the control beam. The network device schedules the service beam to provide random access services for the user equipment.

[0298] After receiving the resource configuration information of the service beam, the user equipment initiates a random access process in the service beam according to the resource configuration information.

[0299] In this embodiment of the present invention, a user device requests service beam resources required for random access in the control beam of a hopping beam. A network device determines service beam resource configuration information based on the service beam resource request and resource utilization status, and transmits the resource configuration information in the control beam. The user device then initiates random access in the service beam based on the resource configuration information. This embodiment simplifies control beam design, reduces control beam power, bandwidth, and other configuration requirements, and increases service beam power configuration, thereby improving resource utilization in the communication system.

[0300] Optionally, the service beam resource request message includes: a detection sequence of the user equipment;

[0301] or

[0302] The service beam resource request message includes: a detection sequence of the user equipment and location information of the user equipment.

[0303] In this embodiment, the service beam resource request message received by the network-side device may include a detection sequence of the user equipment, or may include both the detection sequence of the user equipment and the location information of the user equipment. If the service beam resource request message does not include the location information of the user equipment, the location information of the user equipment may be implicitly indicated by the detection sequence of the user equipment.

[0304] The detection sequence may include one of the following:

[0305] a) First preamble sequence: The first preamble sequence may be a preamble sequence in an existing protocol standard.

[0306] b) a second preamble sequence having a length greater than or equal to the first value; the first value is greater than the length of the preamble sequence in the existing protocol standard, that is, a longer preamble sequence is designed as a detection sequence, such as a PN sequence or ZC sequence with a length of 2048 or 4096. Each user equipment is assigned a detection sequence as a unique identifier of the user equipment, which can improve the detection probability under low signal-to-noise ratio.

[0307] c) A third preamble sequence that has been authorized for scrambling and has a length greater than or equal to the first value. Using a special long PN code that has been authorized for scrambling as a detection sequence, each special user device is assigned a detection sequence that uniquely identifies the user device. Upon receiving this type of detection sequence, the network device can prioritize resource allocation and ensure access to services for special users. This can reduce false detection rates, improve the detection rate of special users, and prevent malicious resource request signals.

[0308] Optionally, the location information includes at least one of the following:

[0309] The latitude, longitude and elevation information of the user equipment on the ground;

[0310] The user equipment's beam position information. The user equipment's location information may be relative location information of the user equipment in the current satellite cell, such as beam position information. A beam position refers to the ground location covered by a hopping beam each time, and the coverage area of ​​each satellite may consist of multiple beam positions.

[0311] Optionally, when the service beam resource request message does not include the location information of the user equipment, the location information of the user equipment may be indicated by a detection sequence in the service beam resource request message, or the RO time-frequency resource may implicitly indicate the location information of the user equipment. For example, the timing of sending the service beam resource request message indicates the location of the user equipment. When the service beam resource request message includes a detection sequence and the location information of the user equipment, the location information of the user equipment may also be implicitly indicated by the detection sequence, or implicitly indicated by the RO time-frequency resource. Specifically, the service beam resource request message implicitly indicates the location information of the user equipment.

[0312] The manner in which the service beam resource request message implicitly indicates the location information of the user equipment includes one of the following:

[0313] a) The detection sequence corresponds to the wave position where the user equipment is located; for example, the detection sequence of the user equipment corresponds to the wave position sequence number of the wave position where the user equipment is located.

[0314] b) The set of detection sequences corresponds to the wave position where the user equipment is located; for example, the set of detection sequences of the user equipment corresponds to the wave position sequence number of the wave position where the user equipment is located, that is, one wave position corresponds to a set of detection sequences.

[0315] c) The detection sequence and the random access channel opportunity (RO) time-frequency resource respectively correspond to the waveband where the user equipment is located. For example, the waveband sequence number of the waveband where the user equipment is located corresponds to one detection sequence and one RO time-frequency resource.

[0316] This embodiment implicitly includes the location information of the user equipment in the service beam resource request message. For example, the wave position of the user equipment can be pre-assigned to the preamble sequence, the time-frequency resource position of the RO, or different detection sequence sets in the protocol. When the network side device detects the service beam resource, it can detect the location of the user equipment.

[0317] Optionally, the location information of the user equipment includes: wave position information of the user equipment;

[0318] Before receiving a service beam resource request message sent by the user equipment in the control beam of the hopping beam, the method further includes:

[0319] Establish the corresponding relationship between wave position information and detection sequence;

[0320] The corresponding relationship is sent to the user equipment.

[0321] In this embodiment, to reduce the uplink overhead when a user device requests service beam resources within a control beam, a detection sequence can implicitly carry the user device's location information. The user device's beam position information within the satellite's coverage area is then mapped to the detection sequence. After the network device detects the user device's uplink detection sequence, it can infer the user device's beam position information within the satellite's coverage area. Specifically, the network device can pre-divide the satellite's coverage area into a large number of beam positions, which can be arranged in a rectangular, square, or cellular layered arrangement. The number of beams depends on the satellite cell range and the coverage range of a single satellite beam. Adjacent beam positions will overlap to achieve complete coverage under the satellite. During system configuration, the satellite's beam positions are pre-numbered. For example, if a satellite is divided into 200 beam positions, the 200 beam positions can be numbered according to a certain rule to obtain the beam position sequence numbers: 0, 1, 2, ..., 199.

[0322] The network-side equipment can pre-assign satellite beam position numbers to available detection sequences. This can be done by mapping one beam position to one detection sequence, one beam position to a group of detection sequences, or one beam position to one detection sequence and one RO time-frequency resource. Ultimately, a one-to-one mapping between beam positions and detection sequences, or between beam positions, detection sequences, and RO resources, is achieved. This allows the network-side equipment to identify the beam position of the user equipment based on the detection sequence and the timing of random access channel transmission.

[0323] Optionally, the method further includes: sending a downlink broadcast signal in the control beam, wherein the downlink broadcast signal includes a wave position sequence number of the control beam.

[0324] When the service beam resource request message includes the wave position information of the user equipment, the wave position information can be the wave position sequence number determined by the user equipment according to the GNSS, or can be the downlink broadcast signal sent by the network side device in the control beam, and the information about the wave position sequence number in the broadcast signal sent by the control beam on each wave position is different. When the user equipment initiates a service beam resource application in the control beam, it first needs to obtain its own wave position information, then determine the corresponding detection sequence based on the wave position information, and finally carry the detection sequence when sending the service beam resource request message to the network side device.

[0325] After receiving the service beam resource request message sent by the user equipment, the network side device configures resource configuration information of the service beam for the user equipment. Optionally, the resource configuration information includes:

[0326] A) Resource request response message: The resource request response in the resource application response message, for example, "0" indicates that no service beam resources can be scheduled.

[0327] B) Service beam scheduling information: This may include the service beam's access time, frequency band configuration, dwell time, etc. For example, the resource configuration information may carry the service beam's index, and the correspondence between the service beam index and the frequency band division may be agreed upon in advance in the protocol.

[0328] It should be noted that the resource configuration information may also include other required information; or, the resource configuration information may include information bits reserved for subsequent function expansion, or include subsequent access mode selection indication, etc.

[0329] Optionally, after sending the resource configuration information to the user equipment in the control beam, the method further includes:

[0330] A random access process initiated by the user equipment is performed in the service beam of the hopping beam.

[0331] The random access mode may include a 4-step access mode and a 2-step access mode. The random access mode may be configured for the network-side device. For example, the network-side device configures the access mode for the user equipment, which may be carried in the resource configuration information, informing the user equipment to select one of the 4-step or 2-step modes to access the service beam, or to first perform the 2-step access mode and then the 4-step access mode, or first perform the 4-step access mode and then the 2-step access mode, etc.

[0332] The random access method can be customized by the user equipment, that is, the user equipment independently selects it. In this case, the user equipment independently selects the 2-step access method or the 4-step access method according to the access method supported by the network side device, or first performs the 2-step access and then the 4-step access method, or first performs the 4-step access and then the 2-step access, etc.

[0333] As an optional embodiment, the specific steps of the four-step access method are: performing a random access process initiated by a user equipment in the service beam of the hopping beam, including:

[0334] 1) receiving a first message sent by the user equipment in the service beam, where the first message includes a physical random access channel (PRACH) signal;

[0335] 2) sending random receive response (RAR) information to the user equipment in the service beam according to the first message;

[0336] 3) receiving a second message sent by the user equipment in the service beam, where the second message includes: a user equipment identifier and a radio resource control (RRC) connection request;

[0337] 4) Sending random access success feedback information to the user equipment in the service beam.

[0338] Optionally, when the service beam resource request message does not include the beam position information of the user equipment, the RAR information includes the beam position information of the user equipment.

[0339] In the embodiment of the present invention, the wave position information of the user equipment may be obtained in the following ways:

[0340] Method 1: The network-side device broadcasts the information of the beam position and the available preamble information of the beam position in the control beam. After obtaining the beam position information, the user equipment selects the preamble to initiate a service beam resource application.

[0341] Method 2: The network side device does not broadcast the beam position information, but the user device knows the beam position allocation rules. The user device can obtain positioning information, calculate the current beam position sequence based on the positioning information and the beam position allocation rules, and select the preamble to apply for service beam resources.

[0342] Method 3: The network side device does not broadcast the wave position information, and the user equipment does not know the wave position division rules. The user equipment can obtain positioning information. When the user equipment initiates a service beam resource application, it carries the location information. The network side device can feedback the wave position information in the RAR of the above random access process.

[0343] As another optional embodiment, the specific steps of the two-step access method: performing a random access process initiated by a user equipment in the service beam of the hopping beam includes:

[0344] 1) receiving a third message sent by the user equipment in the service beam, where the third message includes a PRACH signal, a user equipment identifier, and an RRC connection request;

[0345] 2) Sending random access success feedback information to the user equipment in the service beam.

[0346] The random access process of the embodiment of the present application is described below through specific examples.

[0347] like Figure 7 As shown, it includes: step 71, the network side device receives the service beam resource application Msg1 sent by the user equipment in the control beam, and successfully detects once to determine that there is an access request;

[0348] Step 72: The network-side device decides whether to allocate service beam resources for the service beam resource request of the user equipment and determines resource configuration information based on Msg1 and the current resource utilization status.

[0349] Step 73: The network-side device sends a resource request feedback Msg2 (i.e., the resource configuration information) in the control beam.
