Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a multi-terminal hybrid access method and medium. Background Art

[0002] In a one-to-many wireless system, a time division multiple access method is generally used for terminals that send a stable amount of data (ie, the amount of data sent is a fixed value), while a random access method is generally used for terminals that send an unstable amount of data or a small amount of data.

[0003] For general wireless systems, a multiple access method is conventionally adopted. However, when multiple terminals in this wireless system include terminals with stable data volume and terminals with unstable data volume and small data volume, if only one multiple access method is adopted, it cannot be suitable for the above two types of terminals at the same time, and thus the wireless air interface resources cannot be used well.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] In order to overcome the above defects, the present invention provides a multi-terminal hybrid access method and medium, which can effectively improve the utilization rate of the air interface and increase the total data volume of the wireless system; and has a reasonable and novel working principle, strong control logic and high security.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a hybrid access method for multiple terminals, comprising:

[0007] S1: Provide an access point and at least two terminal groups, each of the terminal groups is composed of a plurality of terminals having the same data transmission attribute, and the data transmission attributes of the terminals belonging to different terminal groups are different;

[0008] S2: the access point sends an access request time and a response time to the terminal in the at least two terminal groups;

[0009] S3: The terminal in the at least two terminal groups may selectively send an access request to the access point at the access request time; wherein the access request includes a terminal identification number and data information;

[0010] S4: The access point determines the terminal type according to the received access request, and sends feedback information to the terminal at the response time; wherein the feedback information includes response data or a data information sending time allocated to the terminal.

[0011] As a further improvement of the present invention, in the above S1, there are two terminal groups, namely a first terminal group and a second terminal group;

[0012] The amount of data sent each time by any terminal in the first terminal group is a fixed value, and the amount of data sent each time by any terminal in the second terminal group is a dynamic value.

[0013] As a further improvement of the present invention, in the above S3, the terminal in the at least two terminal groups may selectively send an access request to the access point at the access request time, including:

[0014] The terminal self-checks whether there is data information to be sent, and if so, sends an access request to the access point at the requested access time; if not, does not send an access request at the requested access time.

[0015] As a further improvement of the present invention, in each of the terminals, the terminal identification number is associated with a data sending attribute of the terminal.

[0016] As a further improvement of the present invention, the access point determines the type of the terminal according to the received access request and sends feedback information to the terminal at the response time; comprising:

[0017] The access point determines the data transmission attribute of the terminal according to the terminal identification number in the received access request,

[0018] If the terminal belongs to the first terminal group, the access point allocates an independent data information sending time to the terminal, and feeds back the data information sending time to the terminal at the response time;

[0019] If the terminal belongs to the second terminal group, the access point sends response data to the terminal at the response time.

[0020] As a further improvement of the present invention, if the terminal in the first terminal group receives the data information sending time at the response time, the terminal will establish a data communication connection with the access point at the data information sending time;

[0021] If the terminal in the first terminal group does not receive the data information sending time within the response time, the terminal will send an access request to the access point again after a delay setting time.

[0022] As a further improvement of the present invention, if the terminal in the second terminal group does not receive the response data within the response time, the terminal will send an access request to the access point again after a delay setting time;

[0023] In addition, the response data includes the terminal identification number.

[0024] As a further improvement of the present invention, when the terminal in the first terminal group receives the data information sending time, if the terminal self-checks that it does not need to send data information, the terminal will establish interaction with the access point at the data information sending time, and the access point will delete the data information sending task corresponding to the data information sending time.

[0025] The present invention also provides a non-volatile computer-readable storage medium on which computer program instructions are stored. When the computer program instructions are executed by a processor, the multi-terminal hybrid access method of the present invention is implemented.

[0026] The beneficial effects of the present invention are as follows: ① Compared with the prior art, the present invention creatively proposes a hybrid access method for multiple terminals, namely: first, multiple terminals are divided into at least two terminal groups according to the data transmission attributes of the terminals; then the access point gives different feedback information to different types of terminals, namely: for terminals with a fixed data volume, the access point allocates an independent data information transmission time to the terminal, so that the terminal establishes a data communication connection with the access point at the data information transmission time; and for terminals with a dynamic data volume, the access point no longer configures additional data information transmission time for them, and when the access point feeds back response data, it indicates that this type of terminal has successfully sent data information. By adopting the above hybrid access method, the utilization rate of the air interface can be effectively improved, thereby greatly increasing the total data volume of the wireless system. ② The working principle of the hybrid access method for multiple terminals described in the present invention is reasonable and novel, with strong control logic and high security.

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Embodiment 1:

[0031] Please refer to the attached Figure 1 As shown, this embodiment 1 provides a hybrid access method for multiple terminals, which mainly includes the following steps:

[0032] S1: Provide an access point and at least two terminal groups, each of the terminal groups is composed of a plurality of terminals having the same data sending attribute, and the data sending attributes of the terminals belonging to different terminal groups are different.

[0033] Specifically, the example in which the terminal groups are configured as two is used for explanation: the two terminal groups are respectively defined as a first terminal group and a second terminal group, and the amount of data sent each time by any terminal in the first terminal group is a fixed value, which can be understood as: the amount of data sent each time by the terminals in the first terminal group is stable; the amount of data sent each time by any terminal in the second terminal group is a dynamic value, which can be understood as: the amount of data sent each time by the terminals in the second terminal group is random and bursty.

[0034] Furthermore, for the first terminal group, the data volumes sent by the multiple terminals therein may be the same, or may be different; it is sufficient to ensure that the data volume sent by each terminal each time is a certain fixed value.

[0035] Similarly, for the second terminal group, the data volumes sent by the multiple terminals therein may be the same or different, as long as each terminal satisfies the requirement that the data volume sent each time is a dynamic value (not fixed). In addition: In this embodiment, the data volumes sent by the terminals in the second terminal group are very small and may be zero.

[0036] S2: The access point sends an access request time and a response time to the terminals in the at least two terminal groups.

[0037] For details, please refer to the attached Figure 2 As shown, if the multiple terminals in the first terminal group are named as: terminal A1, terminal A2, ... terminal An; the multiple terminals in the second terminal group are named as: terminal B1, terminal B2, ... terminal Bn; the terminal A1, terminal A2, ... terminal An, and the terminal B1, terminal B2, ... terminal Bn can respectively establish a two-way communication connection relationship with the access point.

[0038] Therefore, the access point can send public information to the above-mentioned terminal A1, terminal A2, ... terminal An, terminal B1, terminal B2, ... terminal Bn at the same time (of course, not at the same time), and the public information includes: the "access request time" when the terminal sends the access request to the access point, the "response time" when the access point sends feedback information to the terminal, and other information.

[0039] S3: The terminal in the at least two terminal groups may selectively send an access request to the access point at the access request time; wherein the access request includes a terminal identification number and data information.

[0040] Specifically, when the terminal is running, it will use its own self-check function (ie, self-diagnosis function) to check in real time whether it has data information to be sent. If so, it will send an access request to the access point at the requested access time; if not, it will not send an access request at the requested access time.

[0041] Note: It is common knowledge that intelligent terminals have comprehensive self-diagnosis functions and can output self-diagnosis information, so they will not be described in detail here.

[0042] In addition, for the terminal, in order to facilitate tracking and management, etc., a unique code will be compiled after leaving the factory, that is, the terminal identification number. Through the terminal identification number, the relevant configuration model of the terminal can be understood. Therefore, it can be understood that for the terminal A1, terminal A2, ... terminal An, terminal B1, terminal B2, ... terminal Bn in this embodiment, their terminal identification numbers are respectively associated with their respective data transmission attributes.

[0043] S4: The access point determines the terminal type according to the received access request, and sends feedback information to the terminal at the response time; wherein the feedback information includes response data or a data information sending time allocated to the terminal.

[0044] Specifically, the access point determines the terminal type according to the received access request, and sends feedback information to the terminal at the response time; including the following contents:

[0045] S41: The access point determines the data transmission attribute of the terminal according to the terminal identification number in the received access request;

[0046] S42: If the terminal belongs to the first terminal group, the access point allocates an independent data information sending time for the terminal, and feeds back the data information sending time to the terminal at the response time; it can be understood that the terminals in the first terminal group send data to the access point at the designated data information sending time, and the data information sending times of the multiple terminals in the first terminal group are different, that is, for the first terminal group, the times at which the multiple terminals complete data transmission are different;

[0047] If the terminal belongs to the second terminal group, the access point sends response data to the terminal at the response time; understandably, because the amount of data sent by the terminals in the second terminal group is very small, the access point does not configure additional data information sending time. When the terminals in the second terminal group receive the response data, it indicates that the terminal has completed the data transmission. In addition, for the second terminal group, the time for multiple terminals to complete data transmission can be the same or different. The response data includes the terminal identification number.

[0048] Furthermore, when executing the above S4, if the terminal in the first terminal group receives the data information sending time at the response time, then the terminal will establish a data communication connection with the access point at the data information sending time; but if the terminal in the first terminal group does not receive the data information sending time at the response time, then the terminal will send an access request to the access point again after a delay setting time.

[0049] As above, when executing S4, if the terminal in the second terminal group does not receive the response data within the response time, the terminal will also send an access request to the access point again after a delay of a set time.

[0050] Note: The delay time is set by the access point, that is, in the above S2, the public information sent by the access point also includes the delay time.

[0051] In addition, when the terminal in the first terminal group receives the data information sending time, if the terminal self-checks that it does not need to send data information, the terminal will establish interaction with the access point at the data information sending time. At that time, the access point deletes the data information sending task corresponding to the data information sending time.

[0052] Description: The terminal establishes interaction with the access point in the following manner: the terminal sends an interaction request to the access point at the data information sending time, and the interaction request includes a terminal identification number, a request to delete the "data information sending" information, etc.

[0053] In addition, in this embodiment, in order to improve the security during data / signal transmission, encryption and decryption processing can be configured in all data / signal transmission processes, and the encryption and decryption processing method can preferably adopt a symmetric encryption and decryption algorithm or an asymmetric encryption and decryption algorithm.

[0054] Compared with the prior art, this embodiment creatively proposes a hybrid access method for multiple terminals, namely: first, multiple terminals are divided into at least two terminal groups according to the data transmission attributes of the terminals; then the access point gives different feedback information to different types of terminals, namely: for terminals with a fixed data volume, the access point allocates an independent data information transmission time to the terminal, so that the terminal establishes a data communication connection with the access point at the data information transmission time; and for terminals with a dynamic data volume, the access point no longer configures additional data information transmission time for them, and when the access point feeds back response data, it indicates that this type of terminal has successfully sent data information. By adopting the above hybrid access method, the utilization rate of the air interface can be effectively improved, thereby greatly increasing the total data volume of the wireless system. In addition, the working principle of the hybrid access method for multiple terminals is reasonable and novel, with strong control logic and high security.
