Embodiment 1

[0083] Such as figure 1 As shown, this embodiment provides an access control method, the method comprising:

[0084] Step S100: the first type of node sends indication information through a downlink channel; wherein, the indication information includes at least configuration information of a first physical random access channel (PRACH) resource. The indication information may be used to control the second type of nodes to access the first type of nodes.

[0085] The access control method described in the embodiment of the present invention can be applied to a first type of node, and the first type of node can include a macro base station (Macrocell), a micro base station (Microcell), a pico base station (Picocell), and a femto base station ( Femtocell) is also called home base station, low power node (LPN) and relay station (Relay) and other communication nodes.

[0086] The first PRACH resource is a PRACH resource newly configured by the node of the first type after the pre...

Embodiment 2

[0122] Such as figure 2 As shown, this embodiment provides an access control method, the method comprising:

[0123] Step S210: When the first condition is met, the second type of node detects the indication information sent by the first type of node; wherein, the indication information includes at least the configuration information of the first physical random access channel PRACH resource

[0124] Step S220: According to the indication information, send random access signaling to the first type of node through the first PRACH resource.

[0125] The access control method described in this embodiment can be applied to a second type of node, and the second type of node can be a second type of node of human-to-human H2H, a second type of node of machine-to-machine M2M, or a vehicle-to-vehicle V2V The second type of node or the second type of node for device-to-device D2D. Typical representatives of the second type of H2H nodes may include mobile phones and the like. The sec...

example 1

[0192] The first type of node sends indication information to the second type of node through a downlink channel, wherein the second indication information includes at least one of the following:

[0193] First PRACH resource configuration information.

[0194] The indication information may be sent in a random access response message.

[0195] The configuration information of the first PRACH resource includes at least one of the following:

[0196] Time-frequency resource configuration information of the first PRACH resource;

[0197] Carrier information corresponding to the first PRACH resource;

[0198] Index information of the random access sequence of the first PRACH resource;

[0199] Duration information of the first PRACH resource;

[0200] Enabling time information of the first PRACH resource;

[0201] Disabling time information of the first PRACH resource;

[0202] Furthermore, the disabling time information included in the disabling time information of the fir...

Abstract

The embodiment of the invention discloses an access control method and a communication node. The method comprises the following steps: a node of a first type sends indication information through a downlink channel, wherein the indication information at least comprises configuration information of first physical random access channel PRACH resources.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an access control method and a communication node. Background technique [0002] Machine Type Communication (MTC for short) User Equipment (UE for short) (hereinafter referred to as MTC UE), also known as Machine to Machine (M2M for short) user communication equipment, is the main application form. Low power consumption and low cost are important guarantees for its large-scale application. Currently, the M2M devices deployed in the market are mainly based on the Global System of Mobile communication (GSM for short) system. In recent years, due to the improvement of spectrum efficiency of Long Term Evolution (LTE) / LTE-A, more and more mobile operators choose LTE / LTE-A as the future broadband wireless communication system direction of evolution. M2M multi-type data services based on LTE / LTE-A will also be more attractive. Only when the cost of LTE-M2M equipment ca...
