Problems solved by technology

[0028] Obviously, using the same backoff value for so many types of M2M terminals and H2H terminals will cause a high probability of access conflicts between different types of terminals. For H2H terminals and M2M terminals with high priority or important service levels, Its service experience will be seriously affected

Embodiment Construction

[0092] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0093] This embodiment describes an implementation example of the random access control technology of the present invention in an LTE system. Assume that the scenario of the embodiment is an LTE system, and the network element of the access network is an eNodeB (eNB for short).

[0094] The random access control method in this embodiment includes:

[0095] Step 1, the network element of the access network sets a plurality of random access backoff values ​​(hereinafter referred to as backoff values) for each category of terminal classification, and each random access backoff value corresponds to one or more categories;

[0096] The terminal classification method can be but not limited to one or a combination of the following methods:

[0...

Abstract

A method for controlling random access is provided, and the method includes that an access network element sets multiple random access backoff values according to the various types of the terminal classification; the access network element transmits a Random Access Response Media Access Control Protocol Data Unit (RAR MAC PDU) to a terminal, and the RAR MAC PDU contains the information of the random access backoff value set according to the classification; and according the type of the terminal itself, the terminal looks up the corresponding random access backoff value in the RAR MAC PDU to perform the random access delay processing. A system for controlling random access is also provided. With the present invention, the access collision probability of the terminal can be decreased enormously.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless resource scheduling method of a broadband wireless communication system. Background technique [0002] H2H communication refers to the communication between people. People communicate through the operation of equipment. The existing wireless communication technology is developed based on H2H communication. The definition of M2M in the narrow sense is machine-to-machine communication, and the definition in the broad sense is networked applications and services centered on the intelligent interaction of machine terminals. It is based on intelligent machine terminals and uses multiple communication methods as access means to provide customers with informatization solutions to meet customers' informatization needs in monitoring, command and dispatch, data collection and measurement. [0003] The development of wireless technology is an important factor in t...
