Problems solved by technology

In this way, in the scenario where the random access load is heavy, multiple UEs may initiate the next random access immediately, and the system cannot back off random access of different UEs in the time domain, which may cause continuous collision of UEs
Moreover, the random access triggered by the trunking group call service establishment will not get special treatment
In this way, during the trunking group call establishment process, random access may continue to collide, resulting in the introduction of additional delay in the random access process, which in turn affects the time for trunking communication to set up a group call

Embodiment Construction

[0027] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] figure 2 This is the method for setting and updating backoff parameters in the random access process of the present invention, such as figure 2 As shown, the method includes:

[0029] Step 201: In the initialization of the random access procedure of the UE, the backoff parameter is set to an initial value.

[0030] Among them, when the initial value is set, it is performed according to the service type that triggers the UE to perform random access, and the initial value of backoff corresponding to the trunking group call service is the smallest, so that the trunking group call service has the highest priority when performing random access. Specifically, when setting the initial value of backoff, the service type can be classified in advance. The higher the service...

Abstract

The present invention provides a setting and updating method for backoff parameters in a random access procedure. The method comprises: in the initialization of the random access procedure of UE, according to the service type of the UE, setting the backoff parameters to be initial values of the corresponding service type, wherein the initial value corresponding to a trunking group call service is the maximum; in the random access response received by the UE, if a backoff indicator subheader is included, and the service type is not a trucking group call service, updating the backoff parameters of the UE according to the content of the backoff parameter indicator subheader; and otherwise, not updating the backoff parameters of the UE. Via the method of the present invention, the backoff parameter value corresponding to the trunking group call service is enabled to be the maximum; and thereby the interval for establishing random access of the trunking group call service is the minimum, ensuring the priority and accomplishing the access as soon as possible.

Description

Technical field [0001] The present invention relates to random access technology, in particular to a method for setting and updating backoff control parameters in a random access process. Background technique [0002] The broadband digital trunking communication system based on TD-LTE technology can not only support various multimedia services of the TD-LTE mobile communication system itself, but also provide basic trunking call services and trunked multimedia services, such as voice group calling, voice single calling, and Visual group calling, visual single calling, web browsing, mobile office, video playback, video surveillance, video conference and other services. In these services, trunking communication has strict requirements on the time for group call establishment. In order to achieve the rapid establishment of group calls, it is necessary to take a series of measures to ensure the broadband digital trunking communication system based on TD-LTE technology. [0003] Rando...
