Embodiment Construction

[0028] In the following description, specific details are given in order to provide a thorough understanding of the embodiments. However, one of ordinary skill in the art would understand that the described embodiments may be practiced without these specific details. For example, various circuits may be shown in block diagram form in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, structures and techniques have been shown in detail in order not to obscure the described embodiments.

[0029] Also, it should be noted that the described embodiments may be described as processes shown in the form of flowcharts, flowcharts, block diagrams, or block diagrams. Although a flowchart may describe operations as a sequential process, many operations may be performed in parallel or simultaneously. In addition, the order of operations may be rearranged. A process ends when its operation is complete. A procedure may correspond to a met...

Abstract

Various concepts are disclosed in connection with locating a wireless local area network associated with a wireless wide area network. These concepts involve obtaining the difference in transmission time of a marker between two transmitters in a second network, measuring the difference in arrival time of the marker between the two transmitters, and locating the first network based on the difference in transmission time and the difference in arrival time of the marker.

Description

[0001] Claim of priority under 35 U.S.C § 119 [0002] This patent application claims priority to Provisional Application No. 60 / 792,252, filed April 12, 2006, and entitled "SUPPORT OF WLAN ACCESS IN ASSOCIATION WITH WWAN" , which has been assigned to the assignee of the present invention and is incorporated herein by reference. technical field [0003] The present disclosure relates generally to telecommunications and, more particularly, to concepts for locating wireless local area networks associated with wireless wide area networks. Background technique [0004] Wireless networks, such as those supporting GSM, WCDMA, cdma2000, and TDMA, provide wireless coverage over large geographic areas, such as cities, metropolitan areas, states or counties, or sometimes entire countries. This network is sometimes called a WWAN (Wireless Wide Area Network). More recently, smaller wireless networks called WLANs (Wireless Local Area Networks) have been standardized by eg the IEEE 802...
