Description
Message Type
The first field of every management message is
Message Type. To know the value of this field,
refer to the content of MAC management message
in the protocol.
Non-TLV field
This field is sequenced strictly according to the
definition of message format. The corresponding
values of various fields are sorted strictly according to the sequence defined by the message format.
TLV field
This field is a triple field, that is, type-lengthvalue. The message sorts the triple of such field
according to the actual situation.
The R1 interface contains MAC layer and physical layer. The MAC
layer contains three sub-layers, that is, service-specific Convergence Sub-layer (CS), MAC Common Part Sub-layer (MAC CPS)
and security sub-layer in the top-down sequence.
CS sub-layer: The CS sub-layer converts/maps the external data
received by CS-SAP into MAC SDU and transmits the data to MAC
CPS through MAC SAP. The sub-layer classifies external Service
Data Units (SDUs) and associates them with proper SFIDs and
CIDs. It supports the payload head compression function and provides various service-specific convergence sub-layer specifications
for different external protocol interfaces.
MAC CPS sub-layer: The MAC CPS sub-layer does not resolve the
payload at the CS sub-layer. The MAC CPS sub-layer supports
the core functions of the MAC layer, including bandwidth request,
connection setup and maintenance. It receives data of various
CS sub-layers through the MAC SAP and classifies these data by
different MAC connections. Its QoS is applied to transmission and
scheduling above the physical layer.
�
Security sub-layer: The MAC layer contains an independent
security sub-layer that provides authentication, safe key exchange and encryption.
�
The physical layer has multiple specifications, each of which
corresponds to a specific frequency range and application.

Physical Layer
The R1 interface adopts Orthogonal Frequency Division Multiplexing (OFDM) at the physical layer.
R6 Interface
R6 interface defines the processing flow between BS and ASN-GW.
The signaling between the BS and the ASN-GW is transmitted
through the R6 tunnel in the format of User Datagram Protocol
(UDP) plus the signaling format defined by NWG stage 3. The media plane data is borne over the encapsulation tunnel protocol.
UDP bears R6 signaling. Generic Routing Encapsulation (GRE),
Multiple Protocol Label Switching (MPLS) and Virtual Local Area
Network (VLAN) bears R6 data.
The ASN-GW terminates the R6 tunnel from the BS. The R6 tunnel
can adopt various encapsulation technologies, such as GRE, MPLS
and VLAN, and different tunnel granularities are allowed. The R6
data path supports encapsulation protocol and tunnel granularity
negotiation.
