Embodiment Construction

[0023] In the following description, specific details are given to provide a thorough understanding of the described embodiments. However, it will be understood by those of ordinary skill in the art that the described embodiments may be practiced without these specific details. For example, circuitry may not be shown in block diagrams in order not to obscure the embodiments in unnecessary detail.

[0024] Also, it should be noted that the embodiments may be described as processes shown as flowcharts, operational diagrams, structural diagrams, or block diagrams. Although a flowchart may describe operations as a sequential process, many operations may be performed in parallel or simultaneously. Also, the order of the operations may be rearranged. At the same time that its operation is completed, the process ends. A procedure may correspond to a method, a function, a procedure, a subroutine, a subroutine, and so on. When a procedure corresponds to a function, its end correspo...

Abstract

One feature provides a method for encoding geolocation information into a next-generation internet protocol (IP) address, such as IPv6, to facilitate distribution of geolocation information among networked devices. A request for an IP address assignment is received from a network device. The geographical location for the network device is obtained. An IP address is assigned or generated that includes the geographical location. The assigned IP address is then provided to the network device. By encoding the geolocation information of a first network device into the IP address assigned to the first network device, other network devices are able to readily obtain the geographical location of the first network device. This method propagates geolocation information for network devices as part of the IP address, thus avoiding the need for separate geolocation distribution messaging. As the network device moves, its IP address is changed to update its geographical location information.

Description

technical field [0001] Various embodiments of the invention relate to network devices, and more specifically, various embodiments of the invention relate to network infrastructure devices that are aware of their own geographic location and protocols that facilitate geolocation of other network devices. Background technique [0002] Finding the location of a device attached to a network is often difficult, yet such locating is desirable for many commercial, emergency and legal purposes. For example, Voice over IP (VOIP) telephony services rely on knowledge of the geographic information of the telephony device to route emergency calls. Without knowledge of the geographic location of the telephone device, emergency calls cannot be easily routed to the nearest call center. In the event that a caller using a VOIP phone cannot provide an address, emergency services may not be able to locate the caller by other means. Regulations of telephone service also enforce the need to loca...
