1. Introduction
The rapid development of wireless network technology has not only
significantly improved network coverage, network capacity,
transmission rate, and service quality, but also presents the
development trend of diversification of access modes, higher speed of
data transmission, universal mobility and full IP integration. Being
different from wired communication, wireless transmission media are
uncertain and susceptible to unpredictable interferences such as
noise, multipath fading, and shadow effect. Moreover, the inherent
mobility of wireless transmission media also does harm to channel
prediction and channel estimation. It brings considerable problem,
which increases the bit error rate of the channel. In order to
ensure the availability of wireless communication, the conservative
design is often performed according to the requirements of the lowest
channel performance, rather than adaptively adjusting to adapt to the
communication channel. It makes the protocol stack unable to
effectively and reasonably utilize limited power resources and
spectrum resources.
However, existing wireless communication methods ignore the
correlation between the overall requirements of network design and
the functions of each layer. Each layer of the protocol stack is
designed and operated independently, and between layers and layers
only exist interfaces which are static and independent of the
limitation and application of each network layers. This rigorous
layering design method lacks flexibility, compatibility, and does not
fit well into the characteristics of today's networks. In the
practical network communication process, the information between
layers is difficult to share, which also adds a large number of
uncontrollable link overheads, information redundancy, and
communication overhead between peer layers.
The cooperative communication method of the converged multi-media
wireless resource management network described in the proposal can
easily solve these problems. It can change the link type and
facilitate cross-layer design, which not only realizes device
independence, but also achieves the effect communication between
high-level applications and underlying channels.

2. Conventions used in this document
2.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
2.2. Protocol Stack
The protocol stack, is a specific software implementation of the
computer network protocol suite. A protocol in a protocol suite is
usually designed for one purpose only, which makes the design easier.
Each protocol module can usually be treated as a layer in the
protocol stack, because it typically communicates with two other
protocol modules. The lowest level protocol always describes the
physical interaction with the hardware. The user applications only
handle the top-level protocols.
2.3. Wireless Pipe
Wireless Pipe - phytype = "atheros", refers to wireless mesh_Pipe
based on wlan_mwds;
2.4. Ethernet Pipe
Ethernet Pipe - phytype = "ethernet", refers to the two-layered wired
mesh_Pipe in the same broadcast domain;
2.5. Ip Tunnel Pipe
Ip_tunnel Pipe - phytype = "ip_tunnel" is used to establish a three-
layered mesh network across the LAN. It can be divided into two
modes: active one and non-active one according to different working
modes.
2.6. Ip Pipe
Ip Pipe - phytype = "ip", which refers to the ability to extend other
types of links based on the change of the three-layered wired
mesh_Pipe in the same broadcast domain.
3. Joint Access Control and Resource Scheduling

Internet-Draft The CCM of the CMMWRMN May 2021
3.1. Unified Interface
The cooperative communication method of the converged multi-media
wireless resource management network can provide a unified standard
Ethernet interface to users by adapting to protocol specifications of
different media, so that coordination between network layer protocols
can improve the overall performance and efficiency of the wireless
network.
In practical applications, the protocol stack is usually divided into
three main parts: media, transmission, and application. A particular
operating system or platform often has two well-defined software
interfaces: one between the media layer and the transport layer and
the other between the transport layer and the application layer.
3.2. Different Assessment Standards
Different transmission quality assessment methods are adopted for
different media, which requires effective implementation of network
cross-layer radio resource management mechanism which assists in the
design of cross-layer optimal relay node selection algorithm in
cooperative relay network, and supports multi-hop self-organizing
network cross-layer routing.
4. Maximization of the Heterogeneous Network Resources Utilization Rate
4.1. Flexible Networking
The IP Pipe and IP Tunnel are designed to be ones that can change the
link type, which makes the network mode flexible.
4.2. Design Structure
Design structure: mesh - Pipe - link;
4.3. Service Interfaces
Pipe provides a standard Ethernet interface to Mesh. After being
configured in the configuration file G8000.xml, then the Ethernet
port can be treated as a Mesh Pipe. The type of the Box is
Relay/Mobile/Gateway (dual Ethernet port). While the Ethernet port
is used as the Mesh Pipe, it cannot be used as another role at the
same time, such as access users, etc. For example, the device is
connected to the Mesh Pipe through a standard Ethernet interface, and
the Mesh Pipe provides standard adaptation interface to the external
network.

4.4. Link Adaptation
The message format encapsulation and the transmission of
corresponding control instructions are chosen according to different
link transmission standards.
5. Classified Design of Mesh Pipe
Mesh Pipe's classified design technique is mainly showed in the power
control and adaptive modulation and demodulation control according to
the QoS requirements of MAC protocol, routing protocol, TCP protocol
and application layer services.
In the separate unit of a converged multi-media system, all Mesh Pip-
es will provide a unified Ethernet interface.
5.1. Design of Different Link Type
Two-layer and three-layer Pipe are designed according to different
link types. Set two-layer Pipes for Ethernet and link types "ethos".
Set three-layer Pipe for IP Tunnel.
--------------------------------------- | wired Pipe | fiber,covered
wire | --------------------------------------- |wireless
Pipe|scatter,radio,satellite| ---------------------------------------
5.2. Wired and Wireless Design
Designing wired and wireless Pipe is to set wired Pipe for fiber and
covered wire devices, and to set wireless Pipe for scatter, radio and
satellite devices, which achieves the wireless communication between
heterogeneous multi-media.
5.3. Broadband and Narrowband Design
Setting broadband Pipe and narrowband Pipe according to the practical
transmission rate of the device.A broadband Pipe is set for the fiber
devices, and a narrowband Pipe is set for the scattering and the
radio devices.
The structure can achieve multi-media convergence through the
application of Mesh Pipe, and provide a unified network interface for
business units, so the business units has the ability to cross media,
and the business units only need standard Ethernet port access. For
example, communication unit can be linked up to the converged multi-
media wireless communication system not only through the Mac layer
but also through the IP_tunnel Pipe using IP. Regardless of the

access, a unified standard Ethernet interface will be provided by the
converged multi-media wireless communication system.

6. Security Considerations
It is necessary to use the "network ID" to distinguish different ad
hoc networks. Only the ad hoc network node devices (hereinafter
referred to as nodes) configured with the same "network ID" can
discover each other.
Nodes in the same ad hoc network use a unified pre-configured static
key to encrypt the transmitted data. When the keys are different,
nodes cannot transfer data. Even if the eavesdropper acquires the
key seed by some means, he cannot get the final key.
And broadcast data packets and Mesh protocol packets are not
encrypted.
7. IANA Considerations
This document does not include an IANA request.
