Abstract
Methods and apparatus for communicating between an access terminal (AT) and an Access Point (AP) are described. For communications over the air link, between an AP and an AT a PN (Pseudo-random Noise) code based address is used as an AP identifier, e.g., address. The PN code based address may be based on Pilot PN code based signals received from an AP. Thus, the PN based AP address may be determined from pilot signals received from an AP. The PN based AP address may be a shortened version of a PN code corresponding to an AP, a full PN code corresponding to an AP, or a value which can be derived in a known manner from a PN code corresponding to an AP.
Claims14
A method of communicating information to an access terminal, the method comprising:
- determining a PN (Pseudo-random Noise) code address from an IP (Internet Protocol) address corresponding to a remote access point, said IP address including more bits than said PN code address;
- generating, by a serving access point, a packet including the PN code address identifying the remote access point and said packet further including information to be communicated to said access terminal;
- and
- transmitting said generated packet over an airlink to the access terminal.
An apparatus comprising:
- a processor for use in a serving access point, the processor configured to:
- determine a PN (Pseudo-random Noise) code address from an IP (Internet Protocol) address corresponding to a remote access point, said IP address including more bits than said PN code address;
- generate a packet including the PN code address identifying the remote access point and said packet further including information to be communicated to an access terminal;
- and
- transmit said generated packet over an airlink to the access terminal.
A method of operating an access point to communicate information to a remote access point, the method comprising:
- receiving a packet from an access terminal, said packet including a PN (Pseudo-random Noise) code address and information to be communicated to a remote device;
- determining, from an IP address to PN code address mapping information database, an IP (Internet Protocol) address corresponding to said PN code address to be used for communicating the packet to said remote device, said IP address including more bits than said PN code address;
- and
- sending said packet including said information to be communicated, with the IP address, to said remote device.
