    • Methods and apparatus for compressing messages used to support mobile communications are described. After transmission of a first mobile IP message which may be a conventional mobile IP message, a compressed mobile IP message is transmitted. The compressed message includes a new "compressed message" indicator and information which is to replace information in the previous message or to be added to the previous message to construct a new message. In some embodiments, the compressed message includes a mask field, e.g., a sequence of bits, each bit corresponding to one field of a standard registration request message or binding update message. If the mask flag bit corresponding to a field is set, it indicates that the compressed message includes information to replace the content in the corresponding field of the previous message or to be added to the previous message as a field corresponding to the asserted bit.
    • 描述用于压缩用于支持移动通信的消息的方法和装置。 在传输可能是常规移动IP消息的第一移动IP消息之后,发送压缩的移动IP消息。 压缩消息包括一个新的“压缩消息”指示符和信息,该信息将替换先前消息中的信息或被添加到先前消息中以构建新消息。 在一些实施例中,压缩消息包括掩码字段,例如位序列,每个位对应于标准注册请求消息或绑定更新消息的一个字段。 如果设置了对应于字段的掩码标志位,则表示压缩消息包括将先前消息的相应字段中的内容替换或被添加到先前消息中的信息作为对应于被断言位的字段。

    • An apparatus comprising a policy enforcement point (PEP) (110) configured to enforce firewall policies in a network, and a policy decision point (PDP) (120) coupled to the PEP (110) and configured to manage the PEP (110) based on at least one firewall policy option received from at least one node (130,132). Also disclosed in a network component comprising at least one processor configured to implement a method comprising receiving a request from a node (130,132) regarding a firewall policy entry, authenticating the node (130,132), processing the request to manage a firewall (110) using a firewall control protocol, and sending a reply to the node (130,132) regarding processing the request. Also disclosed is a method comprising signaling a PDP (120) to establish a session associated with a source address and a requested protocol, and receiving an indication when the session is allowed.

    • Methods and apparatus related to message compression/decompression are described. A compressed message is generated by indicating what changes are to be made to a previous message to produce the message sought to be transmitted. The required change, in the form of at least one command and corresponding parameter, is transmitted as a compressed version of the message being communicated. This approach takes advantage of the fact that messages sent over time often include much of the same message content and only one or a few fields may have changed. The techniques are general and involve including a command in the compressed message along with at least one parameter. The command indicates processing to be performed on a previous message to generate the uncompressed message. The parameter may be, e.g., data to be inserted into the previous message or specify a location in the previous message where the change is to be made.
    • 描述与消息压缩/解压缩有关的方法和装置。 通过指示对先前消息进行什么改变以产生寻求发送的消息来生成压缩消息。 以至少一个命令和对应参数的形式进行所需的改变作为被传送的消息的压缩版本被发送。 这种方法利用这样的事实,即随着时间的推移发送的消息通常包括大部分相同的消息内容,并且只有一个或几个字段可能已经改变。 这些技术是通用的,并且包括在压缩消息中包括命令以及至少一个参数。 该命令指示对先前消息执行的处理以生成未压缩消息。 该参数可以是例如要插入到先前消息中的数据,或者指定要进行改变的先前消息中的位置。
