这项工作提出了一个MM-MAN（移动的多媒体城域网），其特点是扩展的办公局域网服务作为4G移动的网络的一个组成部分。扩展的LAN服务在移动的终端和它们的家庭办公室LAN之间提供VPN电路，并且允许移动的终端表现得好像它们在家庭办公室LAN中一样。这里的VPN电路是指使用MM-MAN提供的私有IP地址进行IP地址隐藏。负载应该由用户自己隐藏;由于终端被认为是在办公室LAN本身中，因此用户不希望网络运营商对负载进行加密和解密。为了支持快速移动性，MM-MAN采用PON（无源光网络）作为地面网络，下行分组通过PON广播到同一个逻辑宏小区（LMC）中的所有微小区，允许分组通过无线接口传送到任意小区的快速移动终端，上行分组可以从同一个LMC中的任意微小区发出。LMC由几个相邻的微单元组成。为了在微蜂窝环境中加快到移动终端的分组传送，在每个LMC的每个微小区中并行地进行轮询，并且接收响应的微小区将响应多点传送到其它微小区以同步用于下一次轮询。
This work proposes an MM-MAN (mobile multimedia metropolitan area network) featuring extended Office LAN services as a component of the 4G mobile networks. The extended LAN services offer VPN circuits between mobile terminals and their home office LAN, and allow mobile terminals to behave as if they were in the home office LAN. The VPN circuit here means IP address concealment using private IP address offered by the MM-MAN. Payload should be concealed by the users themselves; since the terminal is considered to be in the office LAN itself, and thus, users do not want payload encryption and decryption by the network operator. To support fast mobility, PON (passive optical network) is used as terrestrial network of the MM-MAN. Downlink packets are broadcast through PON to all micro-cells in the same LMC (logical macro-cell) to allow packet transfer over the wireless interface to fast-moving terminals at any cell, and uplink packets can be sent out from any micro-cell in the same LMC. The LMC consists of several adjacent micro-cells. To quicken packet transfer to moving terminals in the micro-cellular environment, polling is conducted in parallel in every micro-cell of each LMC, and the micro-cell, which receives response multicasts the response to other micro-cells to synchronize for the next polling.
