Embodiment 1

[0043] like figure 1 As shown, it is a schematic diagram of the steps of the contention access resource adjustment method in Embodiment 1 of the present invention, and the method mainly includes the following steps:

[0044] Step 101: the base station acquires the number of consecutive failures of contention access reported by the terminal during the process of initiating contention access.

[0045] The concrete realization mode of this step 101 can be:

[0046] Step 1: The base station periodically (for example, every T time) broadcasts available contention access resources to terminals within the coverage area.

[0047] Step 2: The terminals within the coverage of the base station use the contention access resources allocated by the base station to initiate a contention access request, wherein the contention access request includes the failure times of consecutive terminal contention access failures.

[0048] If the terminal does not receive the HARQ sent by the base stati...

Embodiment 2

[0070] like figure 2 As shown, it is a schematic diagram of the steps of the method for sending a contention access request in Embodiment 2 of the present invention, and the method mainly includes the following steps:

[0071] Step 201: the terminal determines contention access resources allocated by the base station.

[0072] The concrete realization mode of this step 201 can be:

[0073] After the terminal enters a cell, it receives contention access resources broadcast by the base station covering the cell. Wherein, the quantity of competing access resources may be represented by resource blocks RB, or may be represented by the number of subcarriers.

[0074] Step 202: Send a contention access request by using contention access resources allocated by the base station.

[0075] The concrete realization mode of this step 202 can be:

[0076]The terminal uses the contention access resources allocated by the base station to send a contention access request, where the conte...

Embodiment 3

[0080] Embodiment 3 is a device for adjusting contention access resources that belongs to the same inventive concept as Embodiment 1, such as image 3 As shown, the device includes:

[0081] The acquiring module 11 is configured to acquire the number of failure times of consecutive contention access failures reported by the terminal during the process of initiating contention access.

[0082] The failure index value determination module 12 is configured to determine a failure index value representing the current competitive access situation according to the failure times, and a larger failure index value indicates a greater probability of a conflict in the current competitive access.

[0083] The adjustment module 13 is configured to adjust the quantity of competing access resources of the base station according to the magnitude relationship between the failure index value and a preset index threshold.

[0084] Specifically, the obtaining module 11 is specifically configured ...

Abstract

The present invention discloses a method for adjusting a contention access resource, and a method and device for sending a contention access request, and the specific contents are: according to failure time for continuous contention access failures of the terminal, determining a failure index value representing a current contention access condition, and according to the determined failure index value, dynamically adjusting the contention access resource allocated to the terminal, wherein the method may allocate reasonable contention access resource to the terminal according to feedbacks of the terminal, which effectively improves the usage rate of the contention access resource.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a contention access resource adjustment method, a contention access request sending method and a device. Background technique [0002] In the prior art, in order to reduce signaling overhead, a contention access method is used to transmit small data packets (such as keep-alive data packets) with low delay sensitivity. The specific implementation process is as follows: [0003] The base station periodically broadcasts contention access resources that can be used for uplink contention access to terminals within the coverage area. According to networks of different standards, the contention access resources can be time-domain resources, frequency-domain resources, or time-frequency resources. Different terminals within the coverage of the base station can use the same contention access resources to send contention access requests, and contention access requests ...
