Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] method embodiment

[0031] In this embodiment, a random access method is provided.

[0032] Such as figure 1 As shown, the random access method according to this embodiment includes the following steps: step S102, divide the access channel into multiple subcategory access channels according to the service category; step S104, allocate media resources for each subcategory access channel respectively; And step S106, when the service to be accessed is trying to access, judge whether there is a subcategory access channel corresponding to the category of the service to be accessed according to the category of the service to be accessed, and perform corresponding operations according to the judgment result.

[0033] Wherein, in step S106, when the judging result is that there is a subcategory access channel corresponding to the category of the service...

Abstract

The present invention provides a method of random access, including step S102, an access channel is divided into multiple sub-class access channels according to the service classes; step S104, each sub class access channel is distributed with a medium resource; and step S106, a service to be accessed attempts to access, whether existing the sub class access channel corresponding to the class of the service to be accessed or not is judged according to the class of the service to be accessed, and processing corresponding operation according to the judging result. In addition, the invention also provides a random access device. The invention resolves reducing the collision probability of the submitted information transmitted by the user end, reducing the unnecessary occupation of the network capacity and waste of resource, and improving the access efficiency.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a random access method and device. Background technique [0002] In cellular systems there is a Random Access Channel (RACH). The random access channel is usually used for the service request performed by the user terminal (UE) when it is turned on for registration, the update information to the network after the location moves, and the transmission of signaling such as uplink when the UE is unplugged. [0003] At present, the core idea of ​​implementing RACH is: when there is information to be transmitted between the sending and receiving parties, the sender randomly occupies wireless resources and sends the information to be transmitted to the receiver. The wireless resources can be frequency resources, time slot resources, and Codeword resources, etc. The specific implementation method is: classify all information that may be transmitted in RACH, different information ...
