Filed:

Appl. No.:

10/409770

Inventors:

Hugh Shieh - Issaquah WA, US
Greg A. Wong - Mercer Island WA, US

Assignee:

AT&T Mobility II LLC - Atlanta GA

International Classification:

H04B 1/38
H04M 1/00
H04M 3/00
H04M 1/66
H04Q 7/20
H04K 1/00

US Classification:

455558, 455410, 455419, 4554352, 455551, 380249

Abstract:

A system and method for activating a subscriber identification module (SIM) based mobile device in a PCS/ANSI type wireless network. The method comprises pre-programming the SIM card of the mobile device with temporary activation identifiers, such as an international mobile station identity (IMSI) and/or a mobile identification number (MIN), and a temporary electronic serial number. The temporary electronic serial number, rather than the mobile device actual electronic serial number, is used to identify the mobile device during registration and activation. The network identifies the temporary electronic serial number associated with the SIM vendor and invokes an over-the-air activation procedure especially for the SIM card mobile devices. A SIM-over-the-air-activation processor is notified to perform the activation for that mobile device on the PCS wireless network. Authentication of the mobile device may be bypassed and the mobile device is instructed to transmit its actual electronic serial number for future registrations.

Filed:

Mar 4, 2002

Appl. No.:

10/091047

Inventors:

Hugh Shieh - Sammamish WA, US

Assignee:

AT&T Wireless Services, Inc.

International Classification:

H04K001/00

US Classification:

713/185000

Abstract:

A binding mechanism uses an authorization token and packet media flow identifier(s) to identify packet media flow(s) of a session for authorization. This provides the advantages of using a per-session authorization token while also allowing resource authorization and allocation on the basis of individual packet media flows of the session. The binding mechanism includes various aspects.

Inventors:

John Myhre - Shoreline WA, US
Venson Shaw - Kirkland WA, US
Hugh Shieh - Sammamish WA, US

International Classification:

H04Q007/20

US Classification:

455/445000, 455/426100

Abstract:

A system and method for allowing a mobile telephone or mobile terminal to interact with its wireless telephone/data service, including conventional 2G and 3G systems (hereinafter the “wireless network”), and also to interact with local-area services such as WLAN, BlueTooth, and personal area networks, and to communicate with and use systems and peripherals available on those networks. Since the mobile terminal is a trusted device on the wireless network, it also then acts as a gateway to allow other local-area services and devices to connect and communicate with the wireless network. When a user of the mobile terminal or a local-area device requests a data service that can be delivered over either the wireless network or the local-area network, the more-efficient data path is determined and the user can select the preferred data path.

Appl. No.:

12/820541

Inventors:

Hugh Shieh - Sammamish WA, US

International Classification:

H04W 40/00

US Classification:

370338

Abstract:

A soft AP module that is installed in the subscriber device is adapted to assign preselected ports numbers as part of its network address translation process. Those port numbers are registered to be used solely for this purpose, port numbers that are registered to applications that are seldomly used, or port numbers in the range 49152-65535. One or more modules in the service provider's facilities analyze the packets that pass through the service provider's facilities. Each module detects the aforementioned predetermined port numbers in the analyzed packets and thus identifies the network load that is attributed to devices the employ the WLANs.
