Description

Unauthorized packet access method, device and system

Technical Field

The present application relates to the field of communications technologies, and in particular, to an unauthorized packet access method, device, and system.

Background

Large-scale Machine Type Communication (mtc) has the characteristics of large connection number, small sending data packet, low data transmission rate and power consumption, dominant uplink Communication, and the like. For access in an mtc scenario with a large scale, a small rate, and a strong burstiness, an unauthorized Non-orthogonal multiple access (NOMA) technology is usually adopted to implement the access.

The NOMA technology is to allocate one resource to multiple terminals, that is, multiple terminals perform power multiplexing on the same resource, thereby improving the utilization rate of the resource. However, multiple terminals perform power multiplexing on the same resource, and resource collision may occur during random access, which may cause network congestion. In order to reduce network congestion, technologies such as Access Class Barring (ACB) or polling are usually adopted for Access, but the adoption of the Access Class technology or the polling technology results in a longer Access delay, which makes the terminal service not well aware and the Access efficiency not high.

Therefore, how to improve the access efficiency of the terminal on the basis of ensuring the service awareness of the terminal is a technical problem to be urgently solved by those skilled in the art.

In order to improve the access efficiency of a terminal on the basis of ensuring the service perception of the terminal, the embodiment of the application provides an unauthorized grouping access method, which obtains the information of the rate to be used of each device to be accessed in M devices to be accessed; determining a rate interval and a resource set corresponding to each packet in the L packets according to the rate information to be used of each device to be accessed; after determining a rate interval and a resource set corresponding to each group, sending access information to M devices to be accessed; the access information is used for indicating a rate interval and a resource set corresponding to each packet, so that each device to be accessed in the M devices to be accessed receives the access device information, and a target packet is selected for access according to the respective rate information to be used and the access information. Compared with the prior art, the priority of each device to be accessed does not need to be distinguished, the access of the device to be accessed with lower priority does not need to be discarded, and the access time delay does not exist, so that the access efficiency of the terminal is improved on the basis of ensuring the service perception of the terminal.

It should be noted that, in this embodiment of the present application, taking a network device as an example of a base station, when the base station determines, according to rate information to be used of each device to be accessed, a rate interval and a resource set corresponding to each of L packets, the base station may be implemented in at least two possible manners, in one possible implementation manner, the base station may first determine the rate interval corresponding to each of the L packets, and then determine a resource set corresponding to each of the L packets according to a sum of rates corresponding to the rate intervals of each of the L packets, and in another possible implementation manner, the base station may first determine the resource set corresponding to each of the L packets, and then determine the rate interval corresponding to each of the L packets according to a resource amount of the resource set corresponding to each of the L packets and the rate information to be used of each device to be accessed. For example, please refer to the following embodiments shown in fig. 2 and fig. 3, fig. 2 is a schematic flowchart of an unauthorized packet access method provided in an embodiment of the present application, and fig. 3 is a schematic flowchart of another unauthorized packet access method provided in an embodiment of the present application. In the following, the access method for these two different unauthorized packets will be described in detail.

In a possible implementation scheme, when determining a rate interval corresponding to each of the L packets first, and then determining a resource set corresponding to each packet according to a sum of rates corresponding to the rate intervals of the packets, for example, as shown in fig. 2, the method for accessing an unauthorized packet may include:

s201, the base station acquires the to-be-used rate information of each to-be-accessed device in the M to-be-accessed devices.

The number of M is not specifically limited in this application, and M is an integer greater than or equal to 2.

It should be noted that, for each device to be accessed, it may correspond to at least one service, each service corresponds to a respective rate requirement, and when the device to be accessed corresponds to multiple services, the rate information to be used of the device to be accessed may be understood as the sum of the rate requirements of all services corresponding to the device to be accessed. However, in general, each device to be accessed only corresponds to a single rate requirement, i.e. its multiple services are services with almost the same rate requirement.

Before obtaining the information of the rate to be used of each device to be accessed in the M devices to be accessed, the base station establishes a connection relationship between the base station and each device to be accessed in advance. For example, in the embodiment of the present application, the connection relationship may be a communication connection between an existing device to be accessed and a base station, and for example, the communication connection may be a communication unauthorized access connection, and after an unauthorized access connection is established between the base station and each device to be accessed, the to-be-used rate information of each device to be accessed in M devices to be accessed may be obtained. Optionally, when the base station acquires the to-be-used rate information of each of the M to-be-accessed devices, the base station may acquire the to-be-used rate information of each to-be-accessed device by receiving the to-be-used rate information reported by each to-be-accessed device; of course, a rate distribution model may also be established according to the historical statistical data of each device to be accessed and the related service model, and the rate information to be used of each device to be accessed is determined according to the established rate distribution model. For example, please refer to fig. 4, fig. 4 is a schematic diagram of a rate probability distribution provided in the present embodiment, a horizontal axis in fig. 4 represents a rate of a device to be accessed, and a vertical axis represents a probability density, which can be seen in conjunction with fig. 4: after a rate distribution model is established according to historical statistical data of the equipment to be accessed and the related service model, the rate information to be used of the equipment to be accessed can be obtained according to the established rate distribution model.

After obtaining the to-be-used rate information of each of the M to-be-accessed devices through S201, the following S202 may be performed:

s202, the base station determines a total rate interval corresponding to the M devices to be accessed and a total resource set required by the M devices to be accessed according to the information of the rate to be used of each device to be accessed.

The total rate interval is a union of the rate intervals corresponding to each group, and the total resource set is a full set of the resource set corresponding to each group. By way of example, the resources of the device to be accessed may include frequency, time and code, which may be denoted as (f, t, c); of course, only any one or two of the frequency, the time, and the code may be included, and the setting may be specifically performed according to actual needs, and here, the embodiment of the present invention is only described by taking as an example that the resource of the device to be accessed may include the frequency, the time, and the code, but the embodiment of the present invention is not limited thereto.

When determining the total rate interval corresponding to the M devices to be accessed, it is necessary to first determine the maximum boundary value and the minimum boundary value of the total rate interval, and determine the total rate interval according to the maximum boundary value and the minimum boundary value of the total rate interval. For example, when determining the maximum boundary value and the minimum boundary value of the total rate interval, the minimum rate of the service executed by each device to be accessed may be determined first, and the minimum rate required by the service executed in all the devices to be accessed is determined as the minimum boundary value of the total rate interval, and the minimum boundary value may be recorded as γ _L So as to obtain the minimum boundary value of the total speed interval; in determining the maximum boundary value of the total rate interval, the maximum boundary value may be

Determining a maximum boundary value of the total rate interval, which may be denoted as γ _M Wherein P is _U The expression denotes the maximum transmission power of the device to be accessed, i.e. the maximum rate requirement of the device to be accessed cannot exceed the maximum power limit of the device itself, N ₀ Representing the system bandwidth, W representing the system bandwidth, thereby obtaining the maximum boundary value of the total rate interval, and further determining the total rate interval corresponding to the M devices to be accessed as [ gamma ] according to the minimum boundary value and the maximum boundary value _L ，γ _M ]。

Optionally, when determining the total resource set required by the M devices to be accessed according to the information of the rate to be used of each device to be accessed, the total resource set may be determined according to the information of the rate to be used of each device to be accessed

And determining a total resource set required by the M devices to be accessed.

indicates the total rate interval [ gamma ] _L ，γ _M ]And in the step (A), M total rates required by the devices to be accessed are obtained, and C represents a second constant.

In this possible implementation scheme, after determining the total rate interval corresponding to the M devices to be accessed and the total resource set required by the M devices to be accessed through S202, S203 may be executed to determine the rate interval corresponding to each packet in the L packets, then S204 may be executed, and the resource set corresponding to each packet is determined according to the sum of the rates of the rate intervals corresponding to each packet and the total resource set, specifically, refer to the following S203 and S204:

s203, the base station divides the total rate interval according to the number L of the packets by equal step length to obtain the rate interval corresponding to each packet.

For example, the number of packets L may be equal to 3, or may also be equal to 5, and may be specifically set according to actual needs, where the number of packets L is specifically not limited further in the embodiment of the present application.

After the total rate intervals corresponding to the M devices to be accessed are determined, the total rate intervals can be divided by equal step length according to the number L of packets to obtain a rate interval corresponding to each packet. Wherein, the rate interval corresponding to the first packet can be marked as [ γ [ ] ₀ ，γ ₁ ]The rate interval corresponding to the second packet may be marked as [ gamma ] ₁ ，γ ₂ ]… the rate interval corresponding to the L-1 th packet can be labeled [ gamma ] _L-2 ，γ _L-1 ]The rate interval corresponding to the lth packet may be labeled [ γ [ ] _L-1 ，γ _L ]That is, the rate interval corresponding to the ith packet can be marked as [ gamma ] _i-1 ，γ _i ]Where i ∈ [1, L ]]After the L packets are marked, the rate interval corresponding to each of the L packets can be specifically calculated. By way of example, may be according to

Dividing the total rate interval, wherein s represents the step size of dividing the total rate interval, after determining the equal step size s, the rate interval corresponding to each of the L packets can be further determined, and the rate interval corresponding to the first packet is [ gamma ], [ gamma ] _L ，γ _L +s]The second packet corresponds to a rate interval of [ gamma ] _L +s，γ _L +2s]The third packet corresponds to a rate interval of [ gamma ] _L +2s，γ _L +3s]… packet number L-1 corresponds to a rate interval of [ gamma ] _L +(L-2)s，γ _L +(L-1)s]The L-th packet corresponds to a rate interval of [ gamma ] _L +(L-1)s，γ _M ]Thereby obtaining the corresponding rate interval of each packet.

It should be noted that, when the total rate interval is divided according to the number L of packets, the total rate interval may be divided according to equal step size, or of course, the total rate interval may not be divided according to equal step size, specifically, the total rate interval may be divided differently according to different rate distribution probability functions. Here, the embodiment of the present application is described by taking an example of dividing the total rate interval into equal steps according to the number of packets L, but the embodiment of the present application is not limited thereto.

After the rate interval corresponding to each of the L packets is calculated, the following S204 may be performed:

and S204, the base station determines the resource set corresponding to each group according to the sum of the rates of the rate intervals corresponding to each group and the total resource set.

After the rate interval corresponding to each group is determined by the calculation of S203, and then the resource set corresponding to each group is determined according to the rate interval corresponding to each group, the resource set corresponding to each group may be divided according to the principle that the sum of the rates of the rate intervals corresponding to each group matches with the resource set corresponding to each group

And dividing the total resource set to obtain a resource set corresponding to each group. Wherein i represents the ith packet of the L packets,

indicates the total rate interval [ gamma ] _i-1 ，γ _i ]Information of the total rate, Δ, required by all devices to be accessed _i Represents the resource amount of the resource set corresponding to the ith group, and each of the resources is represented by Delta _i The full set of (2) constitutes the total resource set.

After determining the rate interval corresponding to each packet and the resource set corresponding to each packet, respectively, access information indicating the rate interval corresponding to each packet and the resource set corresponding to each packet may be sent to each device to be accessed, that is, the following S205 is performed:

s205, the base station sends access information to the M devices to be accessed.

The access information includes a total rate interval, a packet number L, and a resource set corresponding to each packet.

It is noted that in this possible implementationIn the existing method, each device to be accessed can know in advance that the division mode of the total rate interval is equal-step division, so that the base station only needs to divide the total rate interval [ gamma ] gamma _L ，γ _M ]The number of groups L and the resource set corresponding to each group are sent to each device to be accessed, so that the device to be accessed can be according to the total rate interval [ gamma ] _L ，γ _M ]The number of packets L is obtained as the rate interval corresponding to each packet, and of course, the access information may indicate that the rate division method is equal step division.

For example, in this embodiment of the present application, the base station may send access information to M devices to be accessed in a broadcast manner, so that after each device to be accessed receives the access information sent by the base station, the following S206 is executed:

s206, the equipment to be accessed determines a rate interval corresponding to each packet according to the total rate interval and the number L of the packets.

For each device to be accessed, after receiving the access message, the total rate interval may be divided by equal step length according to the number of packets in the access message, so as to obtain the rate interval corresponding to each packet. It should be noted that, the specific method for obtaining the rate interval corresponding to each packet by performing equal-step division on the total rate interval according to the number of packets in the access message may refer to the related description in S203, and here, the embodiments of the present application are not described again.

And S207, selecting a target group by the equipment to be accessed according to the information of the rate to be used, the rate interval corresponding to each group and the resource set, and accessing.

After the rate interval and the resource set corresponding to each packet in the L packets are respectively determined, the rate information to be used of the packet is compared with the rate interval corresponding to each packet, the packet in which the rate information to be used of the packet is located is determined in the L packets as a target packet according to the rate information to be used of the packet, and access is performed according to the rate interval and the resource set corresponding to the target packet.

In this possible implementation manner, when the base station controls each device to be accessed to access, the base station may first obtain rate information to be used of each device to be accessed in the M devices to be accessed, and determine, according to the rate information to be used of each device to be accessed, a total rate interval corresponding to the M devices to be accessed and a total resource set required by the M devices to be accessed; after the total rate interval and the total resource set corresponding to the M devices to be accessed are respectively determined, the total rate interval can be divided in equal step length according to the number L of packets to obtain a rate interval corresponding to each packet, and the resource set corresponding to each packet is determined according to the sum of the rates of the rate intervals corresponding to each packet and the total resource set; after a rate interval and a resource set corresponding to each packet in the L packets are respectively determined, access information is sent to the M devices to be accessed, so that after each device to be accessed receives the access information, the rate interval corresponding to each packet can be determined according to the total rate interval and the packet number L included in the received information, and a target packet is selected according to the rate information to be used, the rate interval corresponding to each packet and the resource set, so that access is performed according to the rate interval and the resource set corresponding to the target packet.

In another possible implementation scheme, when determining a resource set corresponding to each of L packets, and then determining a rate interval corresponding to each packet according to a resource amount of the resource set corresponding to each packet and to-be-used rate information of each device to be accessed, for example, as shown in fig. 3, the method for accessing an unauthorized packet may include:

s301, the base station acquires the to-be-used rate information of each of the M to-be-accessed devices.

S302, the base station determines a total rate interval corresponding to the M devices to be accessed and a total resource set required by the M devices to be accessed according to the information of the rate to be used of each device to be accessed.

It should be noted that, in this embodiment of the present application, a manner in which the S301 base station obtains the to-be-used rate information of each of the M to-be-accessed devices, and a manner in which the S302 base station determines, according to the to-be-used rate information of each of the M to-be-accessed devices, a total rate interval corresponding to the M to-be-accessed devices and a total resource set required by the M to-be-accessed devices are similar to the manner in S201 and S202 in the embodiment shown in fig. 2, and reference may be made to relevant descriptions in S201 and S202 in the embodiment shown in fig. 2, where details of this embodiment are not repeated.

In this possible implementation scheme, after determining the total rate interval corresponding to the M devices to be accessed and the total resource set required by the M devices to be accessed through S302, S303 may be executed to determine the resource set corresponding to each of the L groups, and then S304 may be executed to divide the total rate interval according to the resource amount of the resource set corresponding to each group and the to-be-used rate information of each device to be accessed, so as to obtain the rate interval corresponding to each group, specifically refer to the following S303 and S304:

and S303, the base station performs equal resource division on the total resource set according to the number L of the groups to obtain a resource set corresponding to each group.

When the total resource set is equally divided according to the number of groups L, assuming that the resource amount of the total resource set is M, after the equal resource division is performed, the resource amount of the resource set corresponding to each group is obtained as

And determining the corresponding resource set according to the resource amount of the resource set corresponding to each group, thereby ensuring that the resource amounts corresponding to the resource sets in each group are equal or approximately equal.

After obtaining the resource set corresponding to each group, the following S304 may be performed:

s304, the base station divides the total rate interval according to the resource amount of the resource set corresponding to each group and the to-be-used rate information of each to-be-accessed device to obtain the rate interval corresponding to each group.

After the resource set corresponding to each group is determined by the calculation of S303, when the rate interval corresponding to each group is determined according to the resource amount of the resource set corresponding to each group, the rate interval corresponding to each group may be divided according to a principle that the resource amount of the resource set corresponding to each group matches with the rate interval corresponding to each group, for example, the rate interval corresponding to each group may be divided according to the principle that the resource amount of the resource set corresponding to each group matches with the rate interval corresponding to each group

And dividing the total rate interval to obtain the rate interval corresponding to each packet division. Wherein i represents the ith packet of the L packets,

indicates the total rate interval [ gamma ] _i-1 ，γ _i ]Information of the total rate, Δ, required by all devices to be accessed _i Indicating the resource amount of the resource set corresponding to the ith group, the resource amount of the resource set corresponding to each group is equal or approximately equal, and each delta _i Constitutes the total resource set.

After determining the rate interval corresponding to each packet and the resource set corresponding to each packet, respectively, access information indicating the rate interval corresponding to each packet and the resource set corresponding to each packet may be sent to each device to be accessed, that is, the following S305 is performed:

s305, the base station sends access information to the M devices to be accessed.

The access information includes L +1 boundary values for dividing the total rate interval, and a resource set corresponding to each group.

It should be noted that, in this possible implementation manner, when dividing the rate interval corresponding to each packet, the division is not performed according to equal step length, so that the base station does not send the total rate interval and the number L of packets to the device to be accessed, but needs to send L +1 boundary values for dividing the total rate interval and the resource set corresponding to each packet to each device to be accessed, so that the device to be accessed can determine the rate interval corresponding to L packets according to the L +1 boundary values.

For example, in this embodiment of the present application, the base station may send access information to M devices to be accessed in a broadcast manner, so that after each device to be accessed receives the access information sent by the base station, the following S306 is executed:

s306, the equipment to be accessed determines a rate interval corresponding to each group in the L groups according to the L +1 boundary values.

For each device to be accessed, after receiving the access message, the total rate interval may be divided according to L +1 boundary values in the access message to obtain L rate intervals, and a rate interval corresponding to each packet may be determined. Specifically, the rate interval corresponding to the first boundary value and the second boundary value is the rate interval corresponding to the first packet, the rate interval corresponding to the second boundary value and the third boundary value is the rate interval corresponding to the second packet, and so on, the rate interval corresponding to the lth boundary value and the L +1 th boundary value is the rate interval corresponding to the lth packet, so as to obtain the rate interval corresponding to each packet in the L packets.

S307, the equipment to be accessed selects a target group according to the information of the rate to be used, the rate interval corresponding to each group and the resource set, and accesses the target group.

In this possible implementation, when the base station controls each device to be accessed to access, the base station may first obtain rate information to be used of each device to be accessed in the M devices to be accessed, and determine, according to the rate information to be used of each device to be accessed, a total rate interval corresponding to the M devices to be accessed and a total resource set required by the M devices to be accessed; after the total rate interval and the total resource set corresponding to the M devices to be accessed are respectively determined, the total resource set may be subjected to equal resource division according to the number L of packets to obtain a resource set corresponding to each packet, and the total rate interval may be divided according to the resource amount of the resource set corresponding to each packet and the rate information to be used of each device to be accessed to obtain a rate interval corresponding to each packet; after a rate interval and a resource set corresponding to each of the L packets are respectively determined, access information is sent to the M devices to be accessed, so that after each device to be accessed receives the access information, the rate interval corresponding to each of the L packets is determined according to L +1 boundary values included in the access information, a target packet is selected according to the rate information to be used, the rate interval corresponding to each packet, and the resource set, and access is performed.
