Techniques for synchronizing an emulated wireless communication device over a local link are disclosed. In one aspect, the emulating device monitors received signals for information directed to the emulated device. The information is delivered to the emulated device over the local link. In another aspect, the emulated device updates stored information with the information received over the local link. In yet another aspect, a previously emulated device accesses a wide area network directly, using synchronized information. Various other aspects are also presented. These aspects have benefits including keeping an emulated device synchronized with a wide area network such that post-emulation access attempts are made with updated information and parameters.

1. Field
The present invention relates generally to communications, and more specifically to a novel and improved method and apparatus for synchronizing an emulated wireless communication device over a local link.
2. Background
The features, nature, and advantages of the present invention will become more apparent from the detailed description set forth below when taken in conjunction with the drawings in which like reference characters identify correspondingly throughout and wherein:
FIG. 1 is a general block diagram of a wireless communication system capable of supporting a number of users;
FIG. 2 depicts a portion of a mobile station equipped for emulation;
FIG. 1 is a diagram of a wireless communication system 100 that may be designed to support one or more wireless standards and/or designs (e.g., the W-CDMA standard, the IS-95 standard, the cdma2000 standard, the IS-856 standard, GSM, AMPS). Wireless communication system 100 is but one example of a wide area network that may be deployed within the scope of the present invention.
For simplicity, system 100 is shown to include one base station 104 in communication with two mobile stations 106. It is common to find cellular systems including multiple base stations 104. It also common for multiple cellular systems to interact with each other as well as the Public Switched Telephone Network (PSTN) for voice calls, and with one or more Packet Data Service Nodes (PDSNs) for data communications and connectivity with the Internet (details not shown).
The base station and its coverage area are often collectively referred to as a “cell”. In IS-95 systems, a cell may include one or more sectors. In the W-CDMA specification, each sector of a base station and the sector's coverage area is referred to as a cell. As used herein, the term base station may be used interchangeably with the terms access point or Node B. The term mobile station may be used interchangeably with the terms User Equipment (UE), subscriber unit, subscriber station, access terminal, remote terminal, or other corresponding terms known in the art. The term mobile station encompasses fixed wireless applications.
