    • An embodiment of the present invention provides an apparatus, comprising a transceiver capable of transmitting decreased size management messages in a wireless network by transmitting only differences between subsequently sent management messages and previously sent management messages. The wireless network may be according to the Institute of Electronic and Electrical Engineers (IEEE) latest 802.16 standard. The determination of differences between subsequent management messages may be accomplished by the management message header being extended by an optional field, informing whether the rest of the management message is a full management message or a delta from the previous management message. The management message may be a DL Map (Downlink Map) and UL Map (Uplink Map) and may be transmitted by a base station (BS) in downlink (DL) periodically, in each radio frame and a full map message may still transmitted in predefined intervals for synchronization and to allow new subscriber stations to join the network. Further, a receiver of the management messages may know a previously sent management message and may merge it with changes conveyed in a delta message to obtain a current full map of the management message.
    • 本发明的一个实施例提供了一种装置,其包括能够通过仅发送随后发送的管理消息和先前发送的管理消息之间的差异来在无线网络中发送减小的管理消息的收发器。 无线网络可能根据电子和电气工程师协会(IEEE)最新的802.16标准。 可以通过管理消息报头由可选字段扩展来确定后续管理消息之间的差异的确定,通知管理消息的其余部分是完整管理消息还是来自先前管理消息的增量。 管理消息可以是DL映射(下行链路映射)和UL映射(上行链路映射),并且可以在每个无线电帧中周期性地由下行链路(DL)中的基站(BS)发送,并且全映射消息可以仍然以 用于同步的预定间隔并允许新的用户站加入网络。 此外,管理消息的接收者可以知道先前发送的管理消息,并且可以将其与在增量消息中传送的变化合并,以获得管理消息的当前完整映射。
