    摘要： Addressing methods and apparatus which use airlink resources in an efficient manner are described. In order to use airlink resources efficiently, a variety of address types are supported. The number of bits in the address may vary depending on the type. In order to support a variety of different address types, of different lengths, in one embodiment, an address used for communications over an airlink is constructed by including in the address an address type field used to communicate an address type indicator and, optionally, an address field used to communicate an address value. The address field is variable in length and may be null, requiring the communication of no bits in this field, for certain types of addresses. Four types of addresses which may be supported include: i) an Access Terminal assisted address, ii) a Network assisted address, 3) a Pilot PN based address; and 4) a reserved address.

    摘要翻译： 描述了经由接入点（AP）在接入终端（AT）和远程设备之间进行通信的方法和装置。 对于通过空中链路的通信，在AP和AT之间，与远程设备相对应的短地址用于向/从远程设备路由分组。 这节省了空中链路资源。 然而，为了在AP和远程设备之间进行通信，使用较长的地址，例如对应于远程设备的完整IP地址。 当在远程设备和AT之间传送诸如分组之类的信息时，AT在长地址和短地址之间进行转换。 长地址可以是例如对应于用于通过远程设备和AP之间的二层隧道路由分组的远程设备的IP地址。 在一些实施例中，远程设备是远程接入点。

    摘要： Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.

    摘要： A method for handling a data packet includes a network device receiving the data packet. The method also includes the network device separating first network layer data of the data packet from message data of the data packet. The message data of the data packet includes a source address represented by less than four bytes, a destination address represented by less than four bytes, and a format identifier. The method includes determining whether the destination address of the message data matches an address of the network device or whether the message data indicates a broadcast message. The method also includes the network device processing the format identifier if the destination address of the message data matches the address of the network device or if the message data indicates the broadcast message. The method includes the network device providing the message data to the network device and/or other network devices.
