Abstract
A system and communication method for the system interconnecting the optical network with the radio communication network is provided. The solution mainly applies to an optical access network employing fiber for transmission and the radio communication network connected to the optical access network, wherein a base station of the radio communication network is connected to the optical access network and communicates to an entity in the optical access network to achieve interconnection between the optical network and the radio communication network. After the interconnection is established, a user equipment can enjoy communication services through the interconnected radio communication network and the optical network.

16. A communication method for a system interconnecting an optical network with a radio communication network, comprising:
-
on an uplink, sending, by a user terminal in a radio communication network, a first message to a base station through a Wireless Adaptor (WA), forwarding the first message from the base station to an entity in an optical access network (OAN) and transmitting the first message in the OAN;
transmitting a second message by a user terminal in the OAN, wherein the WA performs a part of the radio interface protocol functions in the Radio Network Layer (RNL) protocol stack;on a downlink, sending, by the entity in the OAN, a third message to the base station through a Wireless Adaptor (WA) and forwarding the third message to the user terminal under the base station in the radio communication network;
sending by a corresponding entity in the OAN, a fourth message to the user terminal in the OAN, wherein the WA performs a part of the radio interface protocol functions in the Radio Network Layer (RNL) protocol stack. - View Dependent Claims (17, 18)
