Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a terminal access method, apparatus, electronic device, and storage medium. Background Art

[0002] In a beam communication system, when a terminal accesses the network side where an access device is located, a multi-beam coverage method is usually adopted. The terminal obtains beam resources by searching for downlink information sent by the access device, and thus accesses the network side based on the obtained beam resources. In an actual beam communication system, the beams emitted by the access device are relatively complex, and the terminal is very likely to access an unreasonable beam. If the beam accessed by the terminal is unreasonable, it will lead to access failure, and then the terminal needs to re-access the network side, resulting in low efficiency of the terminal accessing the network side.

[0062] Advantages of the embodiments of the present application:

[0063] In the technical solution provided by the embodiments of the present application, the network side obtains the location information of the terminal, and thus determines whether to allow the terminal to access the network side on the first beam according to the coverage information of the first beam and the location information of the terminal. When the network side determines that the terminal is not allowed to access on the first beam, it means that it is unreasonable for the terminal to access the network side on the first beam. The network side can prevent the terminal from accessing the network side through an unreasonable first beam, so that the terminal can find other beams for access, rather than waiting for jitter or data transmission failure after accessing the first beam, and then the terminal finds a new beam for access, thereby improving the efficiency of the terminal accessing the network side.

[0064] Of course, it is not necessary for any product or method implementing this application to achieve all of the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application belong to the scope of protection of the present application.

[0079] In a beam communication system, such as a 5G NTN (Non-Terrestrial Network) communication system, a terminal accesses the network side where the access device is located. Usually, a multi-beam coverage method is adopted. The terminal searches for the downlink SSB (Synchronization Signal Block) information sent by the access device and reads the SIB1 (System Information Block 1) bound to the downlink SSB information to obtain the uplink PRACH (Random Access Channel) resource and the Preamble code resource, that is, to obtain beam resources. Then, based on the obtained beam resources, the terminal triggers random access or an RRC (Radio Resource Control) connection to access the beam or cell, that is, to access the network side. The beam communication system may include one or more access devices, and the access device may include a satellite, a space station, a drone, etc.

[0080] As Figure 1 shown, the beam communication system includes a terminal and an access device. Among them, the access device is a device on the network side. The access device emits beams. Among the beams emitted by the access device, there are beams that cover the terminal. The terminal receives the downlink SSB information sent by the access device, thereby obtaining beam resources. Based on the obtained beam resources, the terminal accesses the network side where the access device is located (that is, establishes a service connection). After receiving the access request from the terminal, the access device processes the access request.

[0081] In an actual beam communication system, there are side lobes in the multiple beams emitted by the access device. It is very likely that the terminal will access the side lobes. As Figure 2 shown, some side lobes of beam 1 emitted by the access device are located in the main lobes of other beams (such as beam 3 and beam 4 in the figure). If the terminal accesses the side lobes, it will lead to access failure, and then the terminal needs to re-access the network side, resulting in a low efficiency of the terminal accessing the network side.

[0082] In addition, it is also possible for the terminal to access a beam with a relatively short coverage time. As Figure 2The terminal U shown in the figure is within the main lobe coverage of beam 1 and beam 2. However, the time remaining for the main lobe of beam 2 to cover the terminal U is only 1.5 seconds (s), while the time for the main lobe of beam 1 to cover the terminal U is 1 hour (h). Assuming that the process for the terminal to access the network side takes 2 s, if the terminal U accesses beam 2, it will cause the beam to change before the process of the terminal accessing the network side is completed, resulting in access failure and thus a low efficiency of the terminal accessing the network side. Currently, in the 3GPP (3rd Generation Partnership Project) NTN standard and other existing technologies, there is no solution to the above problem.

[0083] To solve the above problem, an embodiment of the present application provides a terminal access method, which is applied to the network side, as Figure 3 shown, and the method includes the following steps.

[0084] Step S31: Receive a first message sent by the terminal through a first beam of a first access device, where the first message is used to request access to the network side through the first beam.

[0085] Step S32: Obtain the location information of the terminal.

[0086] Step S33: Determine whether the terminal is allowed to access through the first beam based on the coverage information of the first beam and the location information of the terminal.

[0087] In the technical solution provided by the embodiment of the present application, the network side obtains the location information of the terminal, and thus determines whether to allow the terminal to access the network side through the first beam according to the coverage information of the first beam and the location information of the terminal. When the network side determines that the terminal is not allowed to access through the first beam, it means that it is unreasonable for the terminal to access the network side through the first beam. The network side can prevent the terminal from accessing the network side through the unreasonable first beam, so that the terminal can find other beams for access, rather than waiting for jitter or data transmission failure after accessing the first beam and then the terminal finds a new beam for access, thereby improving the efficiency of the terminal accessing the network side.

[0088] In the above step S31, the terminal can be any terminal capable of communicating with the access device, and the network side can be any device such as an access device, a terrestrial base station, a terrestrial network device, a functional device in the core network, a 5G NTN gateway, or a gateway station. The first message can be a random access request message or a radio resource control (RRC) connection establishment access request message. The network side can include one or more access devices. An access device can transmit one or more beams. The first access device is any access device on the network side, and the first beam is any beam transmitted by the first access device. After receiving the beam information transmitted by the access device on the network side, the terminal sends the first message to the first access device through the first beam of the first access device it receives, requesting to access the network side. The network side receives the first message through the first beam of the first access device.

[0089] In the above step S32, the location information of the terminal can include one or more of the tracking area code (TAC) where the terminal is located, the TAC list where the terminal is located, and the longitude and latitude where the terminal is located. The network side can obtain the historical location information of the terminal stored in advance as the location information of the terminal, or obtain the current location information of the terminal from the first message as the location information of the terminal. Specifically, it can include the following two cases.

[0090] Case 1: The first message does not carry the location information of the terminal.

[0091] In this case, the above step S32 can include the following steps: Obtain the identifier of the terminal from the first message; Determine the latest historical location information corresponding to the identifier of the terminal according to the corresponding relationship between the identifier of the terminal and the location information stored in advance, as the location information of the terminal.

[0092] Case 2: The first message carries the current location information of the terminal.

[0093] In this case, the current location information of the terminal is sent to the network side through the first message. The above step S32 can include the following steps: Obtain the current location information of the terminal from the first message as the location information of the terminal.

[0094] In the embodiment of the present application, the network side stores in advance the corresponding relationship between the identifier of the terminal and the historical location information of the terminal. When the first message does not carry the location information of the terminal, the network side can find the location information reported by the terminal last time according to the corresponding relationship between the identifier of the terminal and the historical location information of the terminal stored in advance, as the location information of the terminal, so as to determine whether to allow the terminal to access the first beam subsequently.

[0095] In the embodiments of the present application, the terminal may report location information to the network side. The terminal may be configured with location reporting parameters. When the location reporting parameters meet the preset conditions, the terminal reports location information to the network side. Among them, the location reporting parameters may include a reporting period and / or a location change condition.

[0096] In the embodiments of the present application, after the terminal accesses the first beam, it may periodically report the location information of the terminal to the network side. Thus, the network side can obtain the latest location information of the terminal, so that when the terminal accesses again later, even if the first message sent by the terminal does not carry the location information of the terminal, the network side can use the latest historical location information of the terminal stored in advance as the location information of the terminal according to the historical location information of the terminal. Thus, when the terminal accesses again, the network side can quickly obtain the location information of the terminal, determine whether the first beam accessed by the terminal is allowed to access, that is, determine whether the first beam accessed by the terminal is suitable for access. Furthermore, when the terminal is not suitable for accessing the first beam, the network side can timely give a response of rejecting access to the terminal, so that the terminal can timely find a new beam for access, improving the efficiency of the terminal accessing the network side.

[0097] In the embodiments of the present application, the location change condition includes one or more of the following:

[0098] The resident beam changes, that is, the beam emitted by the access device received by the terminal changes; for example Figure 2 in, the coverage range of beam 2 where terminal U is located no longer covers terminal U. At this time, the terminal meets the location change condition and the terminal can report location information to the network side;

[0099] The TAC where the terminal is located changes;

[0100] The TAC list where the terminal is located changes;

[0101] The distance change between the current longitude and latitude of the terminal and the previous longitude and latitude exceeds the set distance threshold, and the previous longitude and latitude is the longitude and latitude reported by the terminal to the network side last time.

[0102] When the terminal meets the condition that the location has not changed, the first message does not need to carry the location information of the terminal (such as the above situation 1), reducing the load of the message and improving the data transmission efficiency.

[0103] In the above step S33, after obtaining the location information of the terminal, the network side can determine whether the terminal is allowed to access in the first beam according to the coverage information of the first beam and the location information of the terminal.

[0104] In the embodiments of the present application, the network side may determine whether the terminal is allowed to access the first beam based on the main lobe coverage range of the first beam and the location information of the terminal. The network side determines whether the location information of the terminal is within the main lobe coverage range of the first beam to avoid the terminal accessing the side lobe of the first beam. If the location information of the terminal is not within the main lobe coverage range of the first beam, the network side may reject the terminal's access to the first beam or connect the terminal to other beams.

[0105] In the embodiments of the present application, when the network side determines that the terminal is allowed to access the first beam, it indicates that the terminal and the network side can establish a connection through the first beam. The network side may send a random access response message or an RRC connection establishment message indicating that the network side allows the terminal to access the first beam to the terminal.

[0106] In some embodiments, as Figure 4 shown, the embodiments of the present application further provide a terminal access method, including the following steps:

[0107] Step S41: Receive a first message sent by the terminal through the first beam of the first access device. The first message is used to request access to the network side through the first beam. This is the same as step S31 above.

[0108] Step S42: Obtain the location information of the terminal. This is the same as step S32 above.

[0109] Step S43: Determine whether the terminal is allowed to access the first beam based on the coverage information of the first beam and the location information of the terminal. This is the same as step S33 above.

[0110] Step S44: If not allowed, reject the terminal's access to the first beam.

[0111] In the embodiments of the present application, when the network side determines that the terminal is not allowed to access the first beam, it may inform the terminal that it is not allowed to access the first beam by sending a rejection message or information about other beams recommended for the terminal to access to the terminal.

[0112] In the technical solution provided by the embodiments of the present application, when the network side determines that the terminal is not allowed to access the first beam, it indicates that it is unreasonable for the terminal to access the network side through the first beam. The network side may reject the terminal's access so that the terminal can quickly find other beams for access, thereby improving the efficiency of the terminal accessing the network side.

[0113] In some embodiments, the network side may also determine whether the terminal is allowed to access the first beam based on the main lobe coverage range, the main lobe service capability of the first beam, and the location information of the terminal. Based on this, the embodiments of the present application further provide a terminal access method, as Figure 5 shown. This method may include the following steps.

[0114] Step S51: The receiving terminal receives a first message sent through the first beam of the first access device. The first message is used to request access to the network side through the first beam. This is the same as step S31 above.

[0115] Step S52: Obtain the location information of the terminal. This is the same as step S32 above.

[0116] Step S53: Determine whether the location information of the terminal is within the coverage range of the main lobe of the first beam. If not, execute step S54; if so, execute step S55. Refer to the relevant description in step S33 above.

[0117] Step S54: Reject the terminal from accessing the first beam. Refer to the relevant description in step S44 above.

[0118] Step S55: Determine the target time for the first beam to serve the terminal according to the operating trajectory information of the access device and the coverage information of the first beam, that is, the main lobe service ability of the first beam.

[0119] Step S56: Determine whether the target time is less than or equal to the set time threshold. If so, execute step S54; if not, execute step S57.

[0120] Step S57: Connect the terminal to the first beam.

[0121] In the technical solution provided by the embodiment of the present application, after the network side determines that the location information of the terminal is within the coverage range of the main lobe of the first beam, the network side also needs to determine whether the main lobe service ability of the first beam meets the requirement for the terminal to access the first beam. Only when the main lobe service ability of the first beam meets the requirement for the terminal to access the first beam, the terminal is allowed to access, thereby avoiding the situation that the time for the first beam to serve the terminal is short, resulting in the beam being replaced during the process of the terminal accessing the network side and unable to connect normally.

[0122] In step S55 above, the operating trajectory information may be ephemeris information. The coverage range of the first beam may change as the access device moves. The terminal may move or not move, so the time for the first beam to cover the terminal is limited, that is, the main lobe service ability of the first beam is limited. If the time for the first beam to cover the terminal is short, it will cause the first beam to no longer cover the location of the terminal during the process of the terminal accessing the first beam, resulting in access failure. In the embodiment of the present application, after the network side determines that the location information of the terminal is within the coverage range of the main lobe of the first beam, it also needs to determine the target time for the first beam to serve the terminal according to the operating trajectory information of the access device and the coverage information of the first beam, that is, the main lobe service ability of the first beam, so as to further determine whether the terminal is allowed to access through the first beam.

[0123] In the above step S56, the set time threshold can be set to be greater than the time required for the terminal to access the network side, so as to ensure that the process of the terminal accessing the network side is not interrupted. The network side determines whether the target time is less than or equal to the set time threshold. When the target time is less than or equal to the preset time threshold, step S54 is executed to reject the terminal from accessing the first beam; when the target time is greater than the preset time threshold, step S57 is executed to connect the terminal to the first beam.

[0124] In the embodiment of the present application, when the network side determines that the target time is less than or equal to the set time threshold, it indicates that the process of the terminal accessing the network side will be interrupted due to beam change. Then, a random access response message or an RRC connection rejection message can be sent to the terminal to inform the terminal of rejecting access to the first beam.

[0125] In some embodiments, when the network side rejects the terminal from accessing the first beam, it can also send second beam information to the terminal. The second beam is the beam that the network side recommends the terminal to access. The second beam information can be the identifier of the second beam, and the second beam information can be carried in the random access response message or the RRC connection rejection message; as Figure 6 shown, the above step S44 may include the following steps.

[0126] Step S61, select a second beam according to the location information of the terminal, the running trajectory information of at least one access device, and the coverage information of the beams emitted by at least one access device.

[0127] Step S62, send the second beam information to the terminal so that the terminal can send a first message through the second beam.

[0128] In the technical solution provided by the embodiment of the present application, when the network side determines that the terminal should not access through the first beam based on the location information of the terminal, the target time when the first beam covers the terminal, etc., and rejects the terminal from accessing the first beam, it confirms a second beam suitable for the terminal to access according to the location information of the terminal, the running trajectory information of all access devices in the network side, and the coverage information of the beams emitted by these access devices, and sends the second beam information to the terminal so that the terminal can access through the second beam suitable for access, thereby further improving the efficiency of the terminal accessing the network side.

[0129] In the above step S61, the second beam may be a beam transmitted by a second access device. The second access device and the first access device may be the same or different, and the second beam is different from the first beam. The network side prestores the operation trajectory information of at least one access device and the coverage information of the beams transmitted by at least one access device. Among them, the coverage information of the beam, that is, the geographical information of the ground range covered by the beam, such as longitude and latitude information. The network side may select the second beam of the second access device suitable for the terminal to access according to the above information and the current location information of the terminal. In the embodiment of the present application, the network side may select the beam with the optimal signal quality and / or the longest service time as the second beam. For example, if there is a beam in the second access device whose service time for the terminal is much longer than the time required for the terminal to access the network side, the network side will use this beam as the second beam; for another example, among all the beams whose service time for the terminal is greater than the set time threshold, the beam with the optimal signal quality may be selected as the second beam; in addition, thresholds may be set separately for the signal quality and the service time, and the optimal beam may be selected as the second beam by comprehensively considering the signal quality and the service time.

[0130] In the above step S62, the network side sends the second beam information to the terminal according to the second beam determined in the above step S61. After receiving the second beam information, the terminal may search for and access the second beam according to the second beam information, that is, send the first message requesting access to the network side through the second beam, and initiate a new access process to the terminal. For example, the terminal resends the second message for requesting to access the network side through the second beam through the second beam. The network side receives the second message sent by the terminal through the second beam and obtains the location information of the terminal, so as to determine whether the terminal is allowed to access in the second beam.

[0133] In the embodiment of the present application, the third access device and the first access device may be the same or different, and the third beam and the first beam may be the same or different. The network side selects the beam recommended for the terminal to access according to the third beam accessed by the terminal last time, the current location information of the terminal, the operation trajectory information of at least one access device, and the coverage information of the beams transmitted by at least one access device, and uses it as the second beam.

[0134] In the technical solution provided by the embodiment of the present application, when the network side determines the beam for the recommended terminal to access, considering the third beam of the third access device to which the terminal successfully accessed last time can improve the efficiency of determining the beam for the recommended terminal to access. For example, directly using the third beam as the second beam, that is, using the third access device as the second access device.

[0135] In the embodiment of the present application, for the location reporting of the terminal, the location reporting parameters of the terminal can be configured according to RRC states such as RRC connected state, RRC idle state, and RRC inactive state.

[0157] Step S93: The network side sends an RRC connection rejection message for rejecting access to the terminal.
