Embodiment 1

[0164] like image 3 As shown, the embodiment of the present invention provides a bandwidth allocation method, the method can be applied to the EPOC system, the main flow of the method is as follows:

[0165] Step 301: The network device receives a bandwidth request message from the user equipment.

[0166] Specifically, the method in Embodiment 1 may be applied to the network device in the EPOC system.

[0167] In the embodiment of the present invention, the architecture diagram of the EPOC system can be as follows figure 2 shown.

[0168] In the embodiment of the present invention, the network device may be, for example, a CLT or an OLT, and the user equipment may be, for example, a CNU.

[0169] The user equipment may first send the bandwidth request message to the network device.

[0170] In the embodiment of the present invention, for example, the bandwidth request message may specifically be a REPORT (report) message sent by the CNU to the CLT or the OLT. For examp...

Embodiment 2

[0192] See Figure 4 , an embodiment of the present invention provides a bandwidth allocation method, the method can be applied to an EPOC system, and the main flow of the method is as follows:

[0193] Step 401: The network device obtains the conversion relationship between the size of the available resource block RB and the time quantum TQ in the orthogonal frequency division multiplexing OFDM frame of each modulation template in the multiple modulation templates; wherein, the conversion relationship is based on the OFDM frame. It is established by the size of the available RB included in an OFDM frame, and one modulation template corresponds to a set of specific modulation parameters; the network device is connected to multiple user equipments through multiple uplink logical channels divided on one physical channel , where one user equipment corresponds to one uplink logical channel, and one uplink logical channel corresponds to one modulation template.

Embodiment 3

[0248] See Figure 5 , an embodiment of the present invention provides a method for transmitting uplink data, the method can be applied to an EPOC system, and the main flow of the method is as follows:

[0249] Step 501: The user equipment sends a bandwidth request message to the network device.

[0250] Specifically, the method in Embodiment 3 may be applied to the user equipment in the EPOC system.

[0251] In this embodiment of the present invention, when the user equipment needs to transmit uplink data, the bandwidth request message may be sent to the network device.

[0252] Preferably, in this embodiment of the present invention, before sending the bandwidth request message to the network device, the user equipment may first place the TQ for each data queue in the bandwidth request message.

[0253] Wherein, each user equipment may have multiple data queues, and each data queue corresponds to a different bandwidth request, and the corresponding user equipment may separ...

Abstract

The present invention relates to the technical field of communications, and particularly relates to a bandwidth allocation method, device and system, which are used to solve the technical problem that a CLT or an OLT cannot indicate the allocation of time domain and frequency domain at the same time according to time domain information in the prior art. In the embodiments of the present invention, a network device respectively obtains a conversion relationship between the size of an available resource block (RB) in an orthogonal frequency division multiplexing (OFDM) frame of each modulation template in a plurality of modulation templates and a time quantum (TQ) so that a first bandwidth can be determined according to the conversion relationship in an authorization message issued to a user equipment, and thus the allocation of time domain information and frequency domain information can be indicated at the user equipment side.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a bandwidth allocation method, device and system. Background technique [0002] EPOC (Ethernet Passive Optical Network Protocol Over Coaxial PhysicalLayer, Ethernet Passive Optical Network Protocol Coaxial Cable Physical Layer) is a standard project being developed by the IEEE (Institute of Electrical and Electronics Engineers) standards organization. (Ethernet Passive Optical Network, Ethernet Passive Optical Network) technology and protocol are introduced into coaxial network. [0003] Cablelabs (Network Product Industry Certification System) is developing the EPOC system specification, which will be extended to support coaxial support on the basis of the DPOE (DataOver Cable Service Interface Specification Provisioning over EPON) standard. Cable access. [0004] EPOC extends the EPON protocol to the coaxial domain to realize end-to-end management, that ...
