Description

BI value issuing and access request sending method, base station and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a base station, and an apparatus for issuing a BI value and sending an access request.

Background

The number of terminals that each base station can access synchronously is limited by the limitation of the air interface resources and the data processing capability of the base station. If the number of terminals currently accessing to the base station has reached the upper limit of the number of accessible terminals of the base station, at this time, other terminals send access requests to the base station, and the base station is difficult to establish connection with the terminal. In the above case, the base station may send a response including a BI (Backoff Indicator, backoff indication) value to the terminal, where different BI values correspond to different waiting periods, and after the terminal receives the response sent by the base station, the terminal waits for the waiting period corresponding to the BI value carried in the response, and then resends the access request to the base station again. Therefore, the terminal can be prevented from frequently sending the access request to the base station to influence the normal operation of the base station.

However, in the prior art, no matter what application scenario the terminal requests to access the base station, the BI value carried in the response sent by the base station to the terminal is the same fixed value, that is, no matter what application scenario the terminal waits for the same waiting time after receiving the response sent by the base station, and then sends the access request to the base station again. In the prior art, the BI value issued by the base station is relatively fixed, and the requirement of accessing the base station by the terminal under different application scenes is difficult to meet.

Detailed Description

In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present invention means two or more, and other adjectives are similar.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention are included in the scope of protection of the present invention.

In order to meet the requirements of terminals accessing to base stations in different application scenes, the embodiment of the invention provides a BI value issuing and access request sending method, a base station and a device.

The embodiment of the invention provides a BI value issuing method which is applied to a base station and comprises the following steps:

responding to an access request sent by a target terminal, and determining whether the number of the terminals accessed to the base station reaches a preset number;

selecting a BI value matched with the communication quality value as a target BI value;

and issuing a response carrying the target BI value to the target terminal, so that the target terminal transmits an access request to the base station again after waiting for the waiting time corresponding to the target BI value.

The embodiment of the invention provides an access request sending method, which is applied to a terminal and comprises the following steps:

determining a communication power of a target base station for the terminal as a communication quality value;

transmitting an access request containing the communication quality value to the target base station, so that the target base station responds to the access request, and if the number of terminals accessed to the base station reaches a preset number, transmitting a target rollback instruction BI value matched with the communication quality value to the terminals;

From the above, it can be seen that, for the terminal, the communication power of the target base station can represent the communication quality situation between the terminal and the target base station, the access request sent by the terminal to the target base station carries the communication power as the communication quality value, and when the target base station determines that the number of terminals accessed to the target base station has reached the preset number, and the terminal is difficult to access to the target base station, the target base station can directly issue, based on the communication quality value carried in the access request, the target BI value corresponding to the communication quality value to the terminal, so as to control the waiting duration of the terminal before sending the access request to the target terminal again. According to the embodiment, the BI value issued by the base station can be dynamically adjusted according to the communication quality between the target terminal and the base station, so that the requirements of the terminal for accessing the base station in different application scenes are met. In addition, the access request sent by the terminal to the target base station already carries the communication quality value, so that the target base station does not need to additionally determine the communication quality value when determining the target BI value, and the efficiency of the base station for issuing the target BI can be improved.

Referring to fig. 1A, a flowchart of a first BI value issuing method according to an embodiment of the present invention is applied to a base station, and the method includes the following steps S101 to S104.

The base station may be a gNB (next Generation Node B ) base station in an NR (New Radio) system.

Specifically, the embodiment of the present invention may be implemented by a MAC (Medium Access Control ) layer included in the above base station.

S101: and responding to the access request sent by the target terminal, and determining whether the number of the terminals accessed to the base station reaches a preset number.

The preset number is less than or equal to the maximum number of the base station capable of accessing the terminal, and may be set based on the maximum number, for example, the preset number may be the maximum number of the base station capable of accessing the terminal, or may be 90%, 95% or the like of the maximum number, or may be obtained by subtracting a preset difference value from the maximum number. The resource amount of the base station is often fixed, the maximum number of terminals which can be accessed is also fixed, and the maximum number of the base station which can be accessed can be a fixed value estimated based on the resource amount of the base station.

Specifically, if the number of terminals that have accessed the base station has reached the preset number, which means that the base station has accessed a large number of terminals, and it may be difficult to continue accessing other terminals, it may be considered that the target terminal cannot access the base station any more, and step S102 is continued.

Otherwise, the terminal may access the base station through a random access procedure, the terminal may send a random access preamble to the base station, where the random access preamble may be referred to as MSG1 (message 1), indicates that the terminal itself requests to access the base station, after responding to an access request of the target terminal, the base station may allocate PUSCH (Physical Uplink Shared Channel ) resources for transmitting information in a process of establishing a connection between the terminal and the base station to the target terminal, and send information of the allocated PUSCH resources to the target terminal through a random access response, where the random access response may be referred to as MSG2 (message 2), the terminal may send MSG3 to the base station based on PUSCH resources corresponding to the MSG2 after receiving the MSG2, and after the base station receives the MSG3, send a contention resolution identifier to the target terminal, where the contention resolution identifier may be referred to as MSG4 (message 4), and the terminal completes random access after receiving the MSG 4.

That is, the base station allocates PUSCH resources for transmitting MSG3 to the terminal of each access base station, and the number of PUSCH resources allocated by the base station may represent the number of accessed terminals. The maximum number of PUSCH resources that the base station can allocate can be considered to be the maximum number of terminals that the base station can access.

Referring to fig. 1B, a flow chart of a target terminal accessing a base station is provided in an embodiment of the present invention, where the target terminal first sends a random access preamble to the base station, the base station feeds back PUSCH resource information to the target terminal, the target terminal then sends scheduling transmission information to the base station, and the base station sends a contention resolution identifier to the target terminal, so as to complete a process of accessing the target terminal to the base station.

Specifically, the process that the target terminal accesses the base station through the random access manner belongs to the prior art, and this embodiment will not be described in detail.

In one embodiment of the present invention, it may be determined whether the number of terminals having accessed the above base station reaches a preset number through the following step a.

Step A: and determining whether the number of the PUSCH resources allocated by the base station reaches a preset number.

Wherein, the PUSCH resources are used for: information is transmitted during the creation of a connection between the terminal and the base station.

If yes, determining that the number of the terminals accessed to the base station reaches the preset number.

Specifically, the base station may record the number of PUSCH resources allocated, increment the recorded data by 1 each time a terminal accesses the base station, and decrement the recorded data by 1 each time the connection between the terminal and the base station is disconnected. The recorded number may be compared with a preset number, so as to determine whether the number of PUSCH resources allocated by the base station reaches the preset number, and further determine whether the number of terminals accessed to the base station reaches the preset number.

In another embodiment of the present invention, the number of terminals currently connected to the base station may be recorded in the base station, the recorded data may be incremented by 1 each time a terminal is connected to the base station, and the recorded data may be decremented by 1 each time a connection between the terminal and the base station is disconnected. The recorded number may be directly compared with a preset number to determine whether the number of terminals having access to the base station reaches the preset number.

In addition, PL (Physical Channel) in the base station may receive the access request, and send the access request to the MAC layer of the base station, and the MAC layer may perform the step S101.

S102: based on the access request, a communication quality value indicating a communication quality between the target terminal and the base station is obtained.

Specifically, the communication quality value may be: the shorter the target physical distance between the target terminal and the base station, the better the communication quality between the target terminal and the base station is theoretically, and when the communication quality value is the target physical distance, the step S102 may be implemented by the step S102A shown in fig. 2, and the step S103 may be implemented by the step S103A, which is not described in detail herein.

The communication quality value may be: the greater the target terminal communication power, the better the communication quality between the target terminal and the base station, the greater the target terminal communication power, and the step S102 can be implemented by the step S102B shown in fig. 3 and the step S103 can be implemented by the step S103B when the communication quality value is the target terminal communication power, which is not described in detail herein.

The communication quality value may be: the greater the target base station communication power of the base station, the better the communication quality between the target terminal and the base station is theoretically, and when the communication quality value is the target base station communication power, the step S102 may be implemented by the step S102C shown in fig. 4, and the step S103 may be implemented by the step S103C, which will not be described in detail herein.

S103: and selecting the BI value matched with the communication quality value as a target BI value.

Specifically, the protocol specifies a waiting duration corresponding to different BI values, and the shorter the BI value, the shorter the corresponding waiting duration.

Referring to table 1, a table of correspondence between BI values and waiting time is provided for an embodiment of the present invention.

TABLE 1

In one embodiment of the present invention, a correspondence relationship between the communication quality value and the BI value may be preset, so that a target BI value corresponding to the communication quality value may be determined based on the above-described object relationship.

In another embodiment of the present invention, the communication quality level of the target terminal may be determined first based on the communication quality value, and different communication quality levels correspond to different communication quality value intervals, for example, the communication quality levels may be classified into three levels, i.e., a first level, a second level, and a third level, where the communication quality between the target terminal belonging to the first level and the base station is better, a second level, and a third level is worst. In addition, the correspondence between different communication quality levels and different BI values may be preset, and then after determining the communication quality level to which the target terminal belongs, the target BI value corresponding to the target terminal may be determined.

The step S103 may be implemented by a step S103D shown in fig. 5, which will not be described in detail here.

S104: and issuing a response carrying the target BI value to the target terminal, so that the target terminal transmits an access request to the base station again after waiting for the waiting time corresponding to the target BI value.

Specifically, the base station may use a PDU (Protocol Data Unit ) of the MAC layer as the response, and add the target BI value to a BI subheader in the PDU, and the base station may send the target BI value to the target terminal by sending the PDU to the target terminal. The structure of the PDU is defined in the existing protocol, and this embodiment is not described herein.

In addition, the target terminal can determine that the base station cannot be accessed currently after receiving the response, and after reading the target BI value in the response, the target terminal can determine the waiting time corresponding to the target BI value based on the corresponding relation between the BI value and the waiting time, and after the waiting time passes, the target terminal sends an access request to the base station to re-request to access the base station.

Referring to fig. 2, a flow chart of a second BI value issuing method according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 1A, the above step S102 may be implemented by the following step S102A, and the above step S103 may be implemented by the following step S103A.

S102A: and determining a target physical distance between the target terminal and the base station as a communication quality value based on the access request.

In this embodiment, the base station may measure TA (Timing Advance) based on the above access request, and determine a target physical distance between the target terminal and the base station based on the measured TA, where the larger the TA, the larger the target physical distance.

Specifically, the physical distance between the TA and the target may be determined by a method in the prior art, which is not limited in this embodiment.

S103A: and selecting the BI value matched with the target physical distance as a target BI value.

In one embodiment of the present invention, a correspondence between different physical distances and BI values may be preset, and a BI value corresponding to a target physical distance may be selected as a target BI value based on the correspondence.

The BI value may also be determined based on the TA corresponding to the target physical distance, and specifically, reference may be made to the correspondence between BI values and TAs shown in Table 2.

Referring to table 2, a table of correspondence between TA and BI values is provided in an embodiment of the present invention.

TABLE 2

From the above, if the target physical distance between the target terminal and the base station is short, the communication quality between the target terminal and the base station is good. Otherwise, if the target physical distance between the target terminal and the base station is larger, the communication quality between the target terminal and the base station is poorer. The target physical distance can reflect the communication quality between the target terminal and the base station, the target physical distance is used as a communication quality value, and the communication quality between the target terminal and the base station is determined based on the target physical distance, so that the scheme provided by the embodiment of the invention can be realized.

Referring to fig. 3, a flow chart of a third BI value issuing method according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 1A, the above step S102 may be implemented by the following step S102B, and the above step S103 may be implemented by the following step S103B.

S102B: and determining the target terminal communication power of the target terminal as a communication quality value based on the access request.

Specifically, the target terminal communication power is the communication power of the target terminal with respect to the base station, which is measured by the base station itself, and the base station may determine the target communication power by using a method in the prior art, which is not limited in this embodiment.

S103B: and selecting the BI value matched with the communication power of the target terminal as a target BI value.

In one embodiment of the present invention, a correspondence between different terminal communication powers and BI values may be preset, and a BI value corresponding to a target terminal communication power may be selected as a target BI value based on the correspondence.

Referring to table 3, a correspondence table between terminal communication power and BI value is provided in an embodiment of the present invention.

TABLE 3 Table 3

BI value	Terminal communication power (dB)
		0-4	-110 to-50
5-9	-120 to-110
		10-13	-128 to-120

Specifically, only the approximate range of the terminal communication power can be determined based on the access request, so that in the corresponding relation between the preset terminal communication power and the BI values in the embodiment of the invention, each terminal communication power interval is larger, and each terminal communication power interval corresponds to a plurality of BI values. Based on the correspondence, a plurality of BI values matching the communication power of the target terminal may be determined, and one of the BI values may be selected as the target BI value.

In one embodiment of the present invention, one BI value may be randomly selected from the determined BI values as the target BI value, or the target BI value may be selected according to the numerical size of the BI values, for example, the smallest BI value, the second largest BI value, or the largest BI value among them is selected as the target BI value.

From the above, if the communication power of the target terminal between the target terminal and the base station is large, the communication quality between the target terminal and the base station is good. On the contrary, if the communication power of the target terminal between the target terminal and the base station is smaller, the communication quality between the target terminal and the base station is poorer. The communication quality between the target terminal and the base station can be reflected by the communication power of the target terminal, the communication quality between the target terminal and the base station is determined based on the communication power of the target terminal by taking the communication power of the target terminal as a communication quality value, and the scheme provided by the embodiment of the invention can be realized.

Referring to fig. 4, a flow chart of a fourth BI value issuing method according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 1A, the above step S102 may be implemented by the following step S102C, and the above step S103 may be implemented by the following step S103C.

S102C: and acquiring the communication power of the target base station carried in the access request as a communication quality value.

The communication power of the target base station is as follows: and the communication power of the base station determined by the target terminal.

Specifically, the target base station communication power is a communication power of the base station with respect to the target terminal measured by the target terminal, and after the target terminal measures the target base station communication power, the target base station communication power may be added to an access request and transmitted to the base station.

The target terminal may determine the communication power of the target base station in a manner in the prior art, which is not limited in this embodiment.

The target base station communication power may be represented by a Preamble Index (Preamble Index). Wherein the range of the Preamble Index specified by the protocol is 0-59, the value of each Preamble Index corresponds to the range of the base station communication power, the target terminal may record a correspondence between the value of the Preamble Index and the range of the base station communication power, determine the value of the Preamble Index corresponding to the target base station communication power based on the correspondence, and represent the target base station communication power with the determined value of the Preamble Index.

After determining the value of the Preamble Index corresponding to the communication power of the target base station, the target terminal may add the determined value of the Preamble Index to the access request, and send the access request to the base station.

S103C: and selecting the BI value matched with the communication power of the target base station as a target BI value.

In one embodiment of the present invention, a correspondence between different base station communication powers and BI values may be preset, and a BI value corresponding to a target base station communication power may be selected as a target BI value based on the correspondence.

In another embodiment of the present invention, if the terminal uses the Preamble Index to represent the base station communication power, a correspondence between values of different Preamble indices and BI values may be preset, and a BI value corresponding to the value of the Preamble Index carried in the access request is selected as the target BI value based on the correspondence.

Referring to table 4, a correspondence table between values of base station communication power and Preamble Index and BI values is provided for an embodiment of the present invention.

TABLE 4 Table 4

BI value	Value of Preamble Index	Base station communication power (dB)
			0-4	0-19	Greater than-70
5-9	20-39	[-90,-70]
			10-13	40-59	Less than-90

Specifically, the target terminal can only determine the approximate range of the terminal communication power, so in the corresponding relation between the preset base station communication power and the values of the BI value and the Preamble Index in the embodiment of the invention, each base station communication power interval is larger, and each base station communication power interval corresponds to the values of a plurality of BI values and a plurality of Preamble indexes. Based on the correspondence, a plurality of BI values matched with the communication power of the target base station can be determined, a plurality of BI values matched with the value of the Preamble Index carried in the access request can be determined, and one BI value can be selected as the target BI value.

One BI value may be randomly selected from the determined BI values as the target BI value, or the target BI value may be selected according to the value size of the BI value, for example, 0 selects the smallest BI value, the third largest BI value, or the largest BI value among them as the target BI value.

From the above, if the communication power of the target base station between the target terminal and the base station is large, the communication quality between the target terminal and the base station is good. On the contrary, if the communication power of the target base station between the target terminal and the base station is smaller, the communication quality between the target terminal and the base station is poorer. The communication quality between the base station and the target terminal can be reflected by the communication power of the target base station, the communication quality between the target terminal and the base station is determined based on the communication power of the target base station by taking the communication power of the target base station as a communication quality value, and the scheme provided by the embodiment of the invention can be realized. In addition, the access request sent by the terminal to the target base station already carries the communication quality value, so that the target base station does not need to additionally determine the communication quality value when determining the target BI value, and the efficiency of the base station for issuing the target BI can be improved.

Referring to fig. 5, a flowchart of a fifth BI value issuing method according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 1A, the above step S103 may be implemented by the following step S103D.

S103D: and selecting the BI value matched with the communication quality value as a target BI value based on the fact that the better the communication quality indicated by the communication quality value is, the lower the BI value is.

The lower the BI value, the shorter the corresponding waiting time, that is, the shorter the waiting time of the target terminal with better communication quality represented by the communication quality value in the embodiment of the present invention, the target BI value is selected.

Specifically, the better the communication quality between the target terminal and the base station, which is indicated by the communication quality value, the greater the possibility that the target terminal is successfully accessed to the base station is, the base station may control the target terminal to send an access request to the base station again in a shorter time, so that the target terminal can be successfully accessed to the base station in a shorter time. In contrast, the worse the communication quality between the target terminal and the base station, the lower the probability that the target terminal successfully accesses the base station, that is, even if the target terminal sends an access request to the base station, the target terminal may have difficulty in successfully accessing the base station, so the base station may control the target terminal to send the access request to the base station again after a longer time, thereby reserving the resources of accessing the base station to other terminals.

In one embodiment of the present invention, if the communication quality value is the target physical distance, the BI value matching the target physical distance may be selected as the target BI value based on the fact that the smaller the physical distance is, the lower the BI value is.

In particular, in theory, the smaller the physical distance between the target terminal and the base station, the better the communication quality between the two, the smaller the selected BI value may also be.

In another embodiment of the present invention, if the communication quality value is the target terminal communication power, the BI value matched with the target terminal communication power may be selected as the target BI value based on the fact that the larger the terminal communication power is, the lower the BI value is.

Specifically, for the base station, the higher the communication power of the target terminal, which indicates that the larger the signal transmission power of the target terminal, the smaller the interference suffered by the channel between the target terminal and the base station, and the better the communication quality between the target terminal and the base station, the smaller the selected BI value may also be.

In still another embodiment of the present invention, if the communication quality value is the target base station communication power, the BI value matched with the target base station communication power may be selected as the target BI value based on the base station communication power being higher and the BI value being lower.

Specifically, for the target terminal, the higher the communication power of the target base station of the base station, which means that the smaller the interference suffered by the channel between the target terminal and the base station, the better the communication quality between the target terminal and the base station, the smaller the selected BI value may also be.

S601: the communication power of the target base station is determined as a communication quality value.

S602: and sending an access request containing the communication quality value to the target base station, so that the target base station responds to the access request, and when the number of terminals accessed to the base station reaches a preset number, the target base station sends a target BI value matched with the communication quality value to the terminals.

S603: and after waiting for the waiting time corresponding to the target BI value, sending an access request to the target base station again.
