And 6G, universal intelligent networking is realized, and ubiquitous access of massive users is supported. The network coverage objective of 6G will be extended to more natural space than 5G, including space, land, and sea. The 6G network needs to meet differentiated service performance requirements, and higher requirements are put forward on network performance indexes such as data rate, connection number, time delay and the like and networking flexibility. Thus, 6G networks introduce a new type of non-cellular network architecture. The non-cellular architecture adopts a concept of centering on users, and a plurality of distributed access devices are deployed in a network, and centralized signal processing is performed through a central processing unit connected with all the access devices. In this way, widely distributed access devices may achieve a high level of collaboration, covering the entire area.

In a non-cellular network architecture, a terminal may access multiple specific access devices, utilizing spatial macro diversity to improve the spectral efficiency of the network. This means that the terminal can communicate with multiple access devices simultaneously, thereby increasing network capacity and improving user experience.

However, no reasonable way is proposed in the general art as to how a terminal accesses multiple access devices. Thus, there is a need to explore an efficient and rational way of accessing a terminal to multiple access devices.

In view of the above-mentioned drawbacks of the general technology, after the access indication method provided by the present application obtains the transmission performance index between the target terminal and the first access device, the second access device meeting the second preset condition may be determined under the condition that the transmission performance index meets the first preset condition, so as to further send a multiple connection indication to the target terminal through the first access device, so that the target terminal establishes connection with the first access device and at least one second access device at the same time.

Based on the method, under the condition that the transmission performance between the first access equipment and the target terminal is poor, at least one second access equipment with better performance is determined according to the transmission performance of other access equipment, so that the target terminal is simultaneously connected with the first access equipment and the at least one second access equipment, and the transmission performance between the target terminal and the access equipment is improved. Therefore, the terminal can be effectively and reasonably accessed to a plurality of access devices.

The access indication system 100 may comprise a plurality of terminals 101, an access indication means 102, a first access device 103 and a second access device 104.

Fig. 2 is a schematic hardware structure diagram of an access indication device according to an embodiment of the present application. The access indicating means comprise a processor 21, a memory 22, a communication interface 23, a bus 24. The processor 21, the memory 22 and the communication interface 23 may be connected by a bus 24.

The processor 21 is a control center of the access indicating device, and may be one processor or a collective name of a plurality of processing elements. For example, the processor 21 may be a general-purpose central processing unit (central processing unit, CPU), or may be another general-purpose processor. Wherein the general purpose processor may be a microprocessor or any conventional processor or the like.

As one example, processor 21 may include one or more CPUs, such as CPU 0 and CPU 1 shown in fig. 2.

Memory 22 may be, but is not limited to, a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (random access memory, RAM) or other type of dynamic storage device that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), magnetic disk storage or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.

In a possible implementation, the memory 22 may exist separately from the processor 21, and the memory 22 may be connected to the processor 21 by a bus 24 for storing instructions or program code.

It should be noted that the structure shown in fig. 2 does not constitute a limitation of the access indicating device, and the access indicating device may comprise more or less components than shown in fig. 2, or may combine certain components, or may be arranged in different components.

Fig. 3 is a schematic flow chart of an access indication method according to an embodiment of the present application. The access indication method may be applied to the access indication means 102 of the access indication system 100 shown in fig. 1. The access indication method comprises the following steps: S301-S303.

S301, an access indicating device obtains a transmission performance index between a target terminal and first access equipment.

Wherein the transmission performance index comprises one or more of the following: transmission rate, and/or transmission delay, and/or transmission reliability. The transmission rate may be used to represent the ability to transfer data between the target terminal and the first access device. The transmission delay may be used to represent the time required for the target terminal to send data to the first access device, or the time required for the first access device to send data to the target terminal, or the time required for sending data to other terminals in case of a connection between the target terminal and the first access device. The transmission reliability can be determined according to the packet loss rate when data transmission is performed between the target terminal and the first access device.

In one possible manner, the access indication means may send a performance indicator request to the first access device in case the target terminal establishes a communication connection with the first access device. The access indication means may receive a performance indicator response from the first access device and parse the performance indicator response to obtain a transmission performance indicator. The specific implementation manner of the access indication device for obtaining the transmission performance index between the target terminal and the first access device may refer to the following S501-S502, which are not described herein.

S302, the access indicating device determines a second access device meeting a second preset condition under the condition that the transmission performance index meets the first preset condition.

Wherein the first preset condition may include one or more of: the transmission rate is less than a preset rate threshold, the transmission delay is greater than a preset delay threshold, and the transmission reliability is less than a preset reliability threshold. The second preset condition may include: the signal strength is greater than a preset strength threshold and the synchronization deviation is less than a preset deviation threshold.

Optionally, the preset rate threshold may be set according to actual requirements. For example, the preset rate threshold may be 300 megabits per second (megabits per second, mbps) or 500Mbps. This is not particularly limited in this application.

Optionally, the preset delay threshold may be set according to actual requirements. For example, the preset delay threshold may be 1 millisecond or 10 milliseconds. This is not particularly limited in this application.

Alternatively, the preset reliability threshold may be set according to actual requirements. For example, the preset reliability threshold may be 99% or 99.9%. This is not particularly limited in this application.

Optionally, the preset intensity threshold may be set according to actual requirements. For example, the preset intensity threshold may be-99 decibel milliwatts (dBm) or 100dBm. This is not particularly limited in this application.

It is understood that synchronization bias may refer to a time synchronization bias between different access devices. Time synchronization bias refers to a time difference or error between clocks of different access devices. Too large a time synchronization deviation may result in data inconsistencies or application dysfunction.

Alternatively, the synchronization bias may also refer to a frequency synchronization bias between different access devices. The frequency synchronization deviation refers to a frequency difference or an error of different access devices, and represents an offset of an operation rate of each clock with respect to a reference clock. Frequency synchronization bias can cause the clock to produce significant time errors over long periods of time.

Optionally, the preset deviation threshold may be set according to actual requirements. In the case where the synchronization deviation is a time synchronization deviation, the preset deviation threshold may be 10 ns or 100 ns. In the case that the synchronization deviation is a frequency synchronization deviation, the preset deviation threshold may be 10 hz or 1 hz.

In one possible manner, the access indicating means may instruct, by the first access device, the target terminal to send measurement reports corresponding to the plurality of third access devices one to one. The access indication means may receive a plurality of measurement reports from the transmissions of the first access device and synchronization parameters of the first access device with the plurality of third access devices. The synchronization parameters may be used to represent time and/or frequency information of the access devices, and according to the synchronization parameters of different access devices, synchronization bias between different access devices may be determined. The access indication means may determine a synchronization bias for each of the plurality of third access devices based on the plurality of measurement reports and the synchronization parameters of the first access device. The access indicating means may determine that the third access device satisfying the second preset condition is the second access device. The specific implementation manner of the access indication device to determine the second access device satisfying the second preset condition may refer to S401 to S403 described below, which will not be described herein.

S303, the access indicating device sends a multi-connection indication to the target terminal through the first access equipment.

Wherein the multi-connection indication may be used to indicate that the target terminal is simultaneously connected with the first access device and the at least one second access device.

In a possible manner, the access indication device may instruct the target terminal to send the multi-connection indication through the first access device.

Specifically, the access instruction means may send instruction information for instructing the target terminal to make multiple connections to the first access device. The indication information may include a target terminal identification and at least one second access device identification. In response to the indication information, the first access device may send a multi-connection indication to the target terminal. The multiple connection indication may include at least one second access device identification. In response to the multiple connection indication, the target terminal may establish a connection with at least one second access device corresponding to the at least one second access device identification while establishing a connection with the first access device.

In a possible manner, the target terminal may perform data transmission through the first access device and the at least one second access device after being connected to the first access device and the at least one second access device at the same time.

It may be understood that the access indicating device may obtain a transmission performance index of the target terminal after performing multiple connections, and determine another access device that meets a second preset condition when the transmission performance index meets the first preset condition, so as to further perform multiple connections between the target terminal and the other access device.

In one possible manner, the access indication device may access the target terminal to the plurality of access devices in a step-by-step access manner.

Specifically, the access indicating device may instruct the target terminal to access the first access device, and determine whether the target terminal may access at least one second access device at the same time according to the transmission performance index of the target terminal. The access indicating device may not determine the second access device any more if it is determined that the transmission performance index of the target terminal does not meet the first preset condition. That is, the access indicating device may not determine the second access device when the transmission performance of the target terminal after accessing the first access device meets the terminal transmission performance requirement.

Based on the method, the number of the access devices connected with the target terminal can be reduced as much as possible on the premise that the target terminal meets the transmission performance of the terminal, so that the energy consumption of the target terminal and the access devices is saved.

Based on the above technical solution, after the access indication method provided by the present application obtains the transmission performance index between the target terminal and the first access device, the second access device meeting the second preset condition can be determined under the condition that the transmission performance index meets the first preset condition, so that the first access device indicates the target terminal to send the multi-connection indication, and the target terminal can establish connection with the first access device and at least one second access device at the same time.

Based on the method, under the condition that the transmission performance between the first access equipment and the target terminal is poor, at least one second access equipment with better performance is determined according to the transmission performance of other access equipment, so that the target terminal is simultaneously connected with the first access equipment and the at least one second access equipment, and the transmission performance between the target terminal and the access equipment is improved. Therefore, the terminal can be effectively and reasonably accessed to a plurality of access devices.

In an embodiment, when determining at least one second access device that meets a second preset condition, as shown in fig. 4, the access indication method provided in the embodiment of the present application further includes: S401-S403.

S401, the access indicating device acquires a plurality of signal intensities and a plurality of synchronization parameters corresponding to a plurality of third access devices one by one and the synchronization parameters corresponding to the first access devices.

In one possible manner, the access indicating device may instruct, by the first access device, the target terminal to send a plurality of measurement reports corresponding to the plurality of third access devices one by one.

Wherein the measurement report may comprise signal strength. The signal strength may be used to represent the reference signal received power of the access device. In one possible approach, the access device may be an access device that is less than a first preset distance from the target terminal.

Optionally, the first preset distance may be set according to actual requirements. For example, the first preset distance may be 500 meters or 700 meters. This is not particularly limited in this application.

In one possible manner, the access indication device may send, to the target terminal, a measurement report for measuring one-to-one correspondence with the plurality of third access devices and a measurement instruction of the synchronization parameter of the first access device through the first access device. In response to the acquisition instruction, the target terminal transmits the measured measurement reports corresponding to the third access devices one by one and the synchronization parameters of the first access device to the first access device. Wherein the measurement instructions may include a plurality of third access device identifications and a first access device identification.

In one possible approach, the first access device may send a plurality of measurement reports and synchronization parameters of the first access device to the access indication means. The access indication means may receive a plurality of measurement reports from the first access device transmitted and the synchronization parameters of the first access device. The access indicating means may also receive synchronization parameters transmitted from a plurality of third access devices.

S402, the access indicating device determines the synchronization deviation of each third access device in the third access devices based on the synchronization parameters of the third access devices and the synchronization parameters of the first access device, wherein the synchronization parameters correspond to the third access devices one by one.

In one possible manner, the access indicating device may determine the synchronization deviation of each third access device in the plurality of third access devices based on a plurality of synchronization parameters corresponding to the plurality of third access devices one to one and the synchronization parameters of the first access device. That is, the access indicating device may use the difference between the time information in the synchronization parameter of the first access device and the time information in the synchronization parameter of the third access device as the synchronization deviation of the third access device.

In this case, the access indication means may determine the synchronization deviation of each of the plurality of third access devices according to the plurality of synchronization parameters corresponding to the plurality of third access devices one by one and the time information in the synchronization parameters of the first access device. For example, the time information in the synchronization parameter of the third access device a is 10 ns, the time information in the synchronization parameter of the first access device B is 9 ns, and the access instruction device may determine that the time synchronization deviation between the third access device a and the first access device B is 1 ns.

Or, in the case that the synchronization deviation is a frequency synchronization deviation, the access instruction means may determine the synchronization deviation of each of the plurality of third access devices according to the plurality of synchronization parameters corresponding to the plurality of third access devices one to one and the frequency information in the synchronization parameters of the first access device. For example, the frequency information in the synchronization parameter of the third access device a is 11 hz, the frequency information in the synchronization parameter of the first access device B is 10 hz, and the access indicating device may calculate that the frequency synchronization deviation between the third access device a and the first access device B is 1 hz.

S403, the access indicating device determines the third access device meeting the second preset condition as the second access device.

In one possible manner, the access indicating means may determine that the third access device satisfying the second preset condition is the second access device. That is, the access indicating device may determine, as the second access device, a third access device whose signal strength is greater than a preset strength threshold and whose synchronization deviation is less than a preset deviation threshold.

For example, when the preset deviation threshold is 2 hz and the preset intensity threshold is-99 dBm, the access indicating device may determine that the signal intensity-95 dBm corresponding to the third access device a is greater than the preset intensity threshold, and the synchronization deviation corresponding to the third access device a is 1 hz less than the preset deviation threshold.

Based on the above, the method and the device can determine the second access device meeting the second preset condition based on the signal intensity and the synchronization deviation of the plurality of third access devices so as to support the subsequent connection between the target terminal and the second access device. The third access equipment with smaller synchronization deviation and larger signal strength with the first access equipment can be determined to be the second access equipment, so that the target terminal can obtain better signal quality after being accessed to the second access equipment, the cell synchronization process is not required to be executed again, the time-frequency synchronization with the second access equipment is established, the second access equipment can be accessed quickly without synchronization, the access time delay is shortened, and the transmission performance of the terminal is improved. Therefore, the terminal can be effectively and reasonably accessed to a plurality of access devices.

In an embodiment, when acquiring a transmission performance index between a target terminal and a first access device, as shown in fig. 5, the access indication method provided in the embodiment of the present application further includes: S501-S502.

S501, the access indicating device sends a performance index request to the first access equipment.

In one possible manner, the access indicating device may instruct, through the first access device, the target terminal to send the performance index request, so that the target terminal measures and uploads the performance index request with the first access device. The storage module can store transmission performance indexes of preset duration uploaded by the target terminal.

S502, the access indicating device receives the performance index response from the first access equipment and analyzes the performance index response to obtain the transmission performance index.

In one possible manner, the first access device may send, to the access indication device, a performance indicator response including a transmission performance indicator of a preset duration after the transmission performance indicator of the preset duration is stored in the storage module. The access indication means may receive a performance indicator response from the first access device and parse the performance indicator response to obtain a transmission performance indicator.

Alternatively, the first access device may send in real time a performance indicator response including the transmission performance indicator. The access indicating device may receive the performance index response from the first access device, and analyze the performance index response to obtain a transmission performance index, so as to obtain the transmission performance index of the preset duration after the preset duration.

Based on the technical scheme, the access indication method provided by the application can further receive the performance index response from the first access equipment by sending the performance index request to the first access equipment, and analyze the performance index response to obtain the transmission performance index.

Based on the above, the method and the device can acquire the transmission performance index between the target terminal and the first access device, so that at least one second access device is accessed when the transmission performance index is judged to be poor in the follow-up process. Therefore, the terminal can be effectively and reasonably accessed to a plurality of access devices.

In an embodiment, before the target terminal establishes a communication connection with the first access device, as shown in fig. 6, the access indication method provided in the embodiment of the present application further includes: S601-S603.

S601, the access indicating device receives a plurality of terminal access requests corresponding to a plurality of first candidate access devices one by one.

The terminal access request comprises a target terminal identification, the resource utilization rate of the first candidate access equipment and the signal receiving power. The first candidate access device is used for representing an access device capable of receiving an initial access request broadcast by the target terminal, and the signal receiving power of the initial access request is larger than a preset power threshold.

In a possible manner, in the case that the target terminal is a terminal to which the access device is not connected, an initial access request for requesting connection to the access device may be broadcast using a preset time-frequency resource. The initial access request may include a target terminal identification. The access device may receive an initial access request broadcast from a target terminal at a preset time-frequency resource, and may send, as a first candidate access device, the terminal access request to the access indication device when the signal received power is greater than a preset power threshold. The access indication means may receive a plurality of terminal access requests in one-to-one correspondence with the plurality of first candidate access devices.

S602, the access indicating device determines a first candidate access device meeting a third preset condition from the plurality of first candidate access devices as the first access device.

The third preset condition includes that the resource utilization rate is smaller than a preset utilization rate threshold value, and the signal receiving power is larger than other first candidate access devices.

In one possible manner, the access indication device may analyze a plurality of terminal access requests corresponding to a plurality of first candidate access devices one by one, so as to obtain a resource utilization rate and a signal receiving power corresponding to a plurality of first candidate access devices one by one. The access indicating device may determine, as the first access device, a first candidate access device satisfying a third preset condition from among the plurality of first candidate access devices through resource utilization rates and signal receiving powers corresponding to the plurality of first candidate access devices one by one.

Optionally, the preset utilization threshold may be set according to actual requirements. For example, the preset utilization threshold may be 50% or 30%. This is not particularly limited in this application.

For example, in the case that the preset utilization threshold is 30%, the access indicating device may determine that the resource utilization is 25% and the signal receiving power is greater than that of the other first candidate access devices C as the first access device.

S603, the access indication device sends a terminal access indication to the first access equipment so that the first access equipment establishes connection with the target terminal.

The terminal access indication may be used to instruct the first access device to send an access indication signal to the target terminal. The access indication signal may be used to indicate that the target terminal accesses the first access device, and may include a target terminal identification and a synchronization parameter of the first access device.

In one possible manner, after determining the first access device, the access indication means sends a terminal access indication to the first access device. The first access device may receive and establish a connection with the target terminal in response to the terminal access indication.

In one possible manner, the first access device establishes a connection with the target terminal, and the target terminal may perform data transmission through the first access device.

Based on the above technical solution, the access indication method provided by the present application may receive a plurality of terminal access requests corresponding to a plurality of first candidate access devices one by one, and determine, as the first access device, a first candidate access device satisfying a third preset condition in the plurality of first candidate access devices, so as to further send a terminal access indication to the first access device, so that the first access device establishes a connection with the target terminal.

Based on the above, the method and the device can determine the first access device with better transmission performance from a plurality of first candidate access devices and connect the target terminal with the first access device under the condition that the target terminal is a terminal which is not connected with the access device. By determining the first access device, the target terminal can access the access device with optimal signal coverage in the initial access stage, and the transmission performance of the terminal is ensured. Therefore, the terminal and the access equipment can be effectively and reasonably connected.

In an embodiment, before the target terminal establishes a communication connection with the first access device, as shown in fig. 7, the access indication method provided in the embodiment of the present application further includes: S701-S703.

S701, the access indicating device receives a transmission request for establishing data transmission by the target terminal sent by the fourth access device.

Wherein the transmission request includes the target terminal identification, the distance between the second candidate access device and the target terminal, and the resource utilization of the second candidate access device. The fourth access device is used for indicating the access device to which the target terminal is currently connected.

In a possible manner, in a case where the target terminal is a terminal to which the fourth access device is connected, the target terminal may send a transmission request to the fourth access device when data transmission is required. The fourth access device receives and responds to the transmission request and forwards the transmission request to the access indication means. The access indicating device may receive a transmission request for establishing data transmission by the target terminal sent by the fourth access device, and analyze the transmission request to obtain the target terminal identifier, the distance between the second candidate access device and the target terminal, and the resource utilization rate of the second candidate access device.

Alternatively, the transmission request may be a radio resource control (radio resource control, RRC) message for controlling and managing radio resources in the wireless communication.

S702, the access indicating device determines the second candidate access device meeting the fourth preset condition as the first access device.

The fourth preset condition is used for indicating that the resource utilization rate is smaller than a preset utilization rate threshold value and the distance between the fourth preset condition and the target terminal is smaller than the distance between other second candidate access equipment and the target terminal.

Optionally, the second candidate access device is any one access device in the preset area.

Optionally, the preset area may be set according to actual requirements. For example, the preset area may be a circular area with a radius of 500 meters centered on the target terminal. This is not particularly limited in this application.

In one possible manner, the access indicating device may determine whether the second candidate access device meets a fourth preset condition, that is, whether the resource utilization rate of the second candidate access device is less than a preset utilization rate threshold, and whether a distance between the second candidate access device and the target terminal is less than that of other second candidate access devices. The access indicating device may preset the second candidate access device meeting the fourth preset condition in the area, and determine the second candidate access device as the first access device.

For example, in the case where the preset utilization threshold is 30%, the access indicating means may determine, as the first access device, a second candidate access device C having a resource utilization of 20% and a distance from the target terminal smaller than other second candidate access devices.

S703, the access indication device sends a terminal access indication to the first access equipment so as to enable the first access equipment to establish connection with the target terminal.

In one possible manner, after determining the first access device, the access indication means sends a terminal access indication to the fourth access device. The fourth access device may receive and respond to the terminal access indication by sending a handover indication message to the target terminal. The handover indication message may be used to instruct the target terminal to re-access the first access device, and the handover indication message may include the first access device identification. In response to the handover indication message, the target terminal may disconnect from the fourth access device and access the first access device.

In one possible manner, after the first access device establishes a connection with the target terminal, the target terminal may perform data transmission through the first access device.

It is understood that the access indicating means is not used to perform S703 in case the first access device is identical to the fourth access device. That is, in the case where the first access device is the same as the fourth access device, the access instruction means does not need to transmit the terminal access instruction to the fourth access device.

Based on the above technical solution, the access indication method provided in the present application may receive a transmission request for establishing data transmission by the target terminal sent by the fourth access device, and then determine the second candidate access device meeting the fourth preset condition as the first access device, so as to further send a terminal access indication to the first access device, so that the first access device establishes a connection with the target terminal.

Based on the method, the first access device capable of meeting the data transmission of the terminal can be determined according to the distance between the terminal and the access device and the resource utilization rate of the access device, and the terminal is connected with the access device. The first access device may provide better signal coverage and meet the resource requirements of the terminal traffic transmission. Therefore, when the first access device is different from the fourth access device, the target terminal can be instructed to disconnect from the fourth access device and switch to the first access device, so as to improve the transmission performance of the terminal. Therefore, the terminal can be effectively and reasonably connected with the access equipment with better performance.
