Patent number: 9204292Abstract: An open service provisioning method may be implemented by a terminal. The method may include receiving a customer's selection of a first-time network access provider and network service provider (NAP/NSP). The method may also include establishing a connection with the first-time NAP/NSP. The method may also include receiving information about possible other NAPs/NSPs while connected to the first-time NAP/NSP. The method may also include receiving the customer's selection of a home NAP/NSP. The method may also include assisting the customer to sign up for service with the home NAP/NSP. The method may further include establishing a connection with the home NAP/NSP.Type: GrantFiled: October 20, 2008Date of Patent: December 1, 2015Assignee: QUALCOMM IncorporatedInventors: Guangming Carl Shi, Kuo-Chun Lee, Steven Cheng, Isaac Ta-yan Siu

Patent number: 9020505Abstract: Methods and apparatus for using network topology and coverage information from one radio access technology (RAT) network to assist acquisition of another different RAT network for a multi-mode mobile station (MS), such as acquiring a WiMAX (Worldwide Interoperability for Microwave Access) network based on topology and coverage information about a 3G (Third Generation) network and vice versa, are provided. Base station (BS) acquisition assisted in this manner may provide for quick restoration of a previously interrupted or deactivated network service, while decreasing the power consumption of the multi-mode MS during a power savings state because periodic scanning and registration need not occur.Type: GrantFiled: September 17, 2008Date of Patent: April 28, 2015Assignee: QUALCOMM IncorporatedInventors: Isaac Ta-yan Siu, Guangming Carl Shi, Nitin Pant

Patent number: 8948069Abstract: Certain embodiments of the present disclosure improve a robustness of some critical MAC management response massages transmitted from a base station (BS) to a mobile station (MS). In this way, a reliability of transmission can be increased and a messaging failure that results in out of sync state between the MS and the BS can be avoided.Type: GrantFiled: January 9, 2009Date of Patent: February 3, 2015Assignee: QUALCOMM IncorporatedInventors: Steven Cheng, Guangming Carl Shi, Tom Chin, Isaac Ta-yan Siu, Kuo-Chun Lee

Patent number: 8554205Abstract: A method for facilitating dynamic service-based system selection and determination may be implemented by a communications device. The method may include presenting system selection options to a user based on information that is received about Network Access Providers (NAPs) and Network Service Providers (NSPs). The method may also include receiving user input about the system selection options. The user may be permitted to provide input about specific services offered by specific NSPs. The method may also include determining user preferences regarding system selection based on the user input. The method may also include creating a preferred roaming list (PRL) based on the user preferences. The method may further include using the PRL to scan for available networks and channels and to find serving systems.Type: GrantFiled: October 23, 2008Date of Patent: October 8, 2013Assignee: QUALCOMM IncorporatedInventors: Guangming Carl Shi, Kuo-Chun Lee, Steven Cheng, Isaac Ta-yan Siu

Patent number: 8218466Abstract: A base station and a subscriber station may negotiate paging parameters so that the subscriber station can enter idle mode. After the subscriber station has entered idle mode, the base station may change at least one paging parameter at the base station. The base station may direct the subscriber station to change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode. The subscriber station may change at least one paging parameter at the subscriber station after the subscriber station has entered idle mode.Type: GrantFiled: March 17, 2009Date of Patent: July 10, 2012Assignee: QUALCOMM IncorporatedInventors: Tom Chin, Fangqi Hu, Kuo-Chun Lee, Guangming Carl Shi, Isaac Ta-yan Siu, Doo Seok Kim

Publication number: 20100189070Abstract: The present disclosure proposes a method for incorporating a procedure of adding/changing a service flow of a mobile station into a handover process in order to avoid problem that the mobile station can handover to a neighbor base station that do not support the requested service flow operation. Furthermore, the proposed disclosure can reduce the processing delay by combining the handover process of the mobile station and the procedure of adding/changing the service flow.Type: ApplicationFiled: January 27, 2009Publication date: July 29, 2010Applicant: QUALCOMM INCORPORATEDInventors: Guangming Carl Shi, Fangqi Hu, Isaac Ta-yan Siu, Wei Zhang, Kuo-Chun Lee

Publication number: 20100069070Abstract: Methods and apparatus for using a location of a mobile station (MS) to assist network entry and initialization, scanning, and/or handover operations in a radio access technology (RAT), such as WiMAX (Worldwide Interoperability for Microwave Access), are provided. The location of the MS may be ascertained by determining the Global Positioning System (GPS) coordinates of the MS internally or by receiving the location from a GPS device external to the MS. Knowledge of the current or future location of the MS may reduce the amount of base station (BS) information transmitted to the MS; may reduce the power consumption and the amount of time spent during network entry, scanning, or handover; and may increase the bandwidth usage efficiency.Type: ApplicationFiled: September 17, 2008Publication date: March 18, 2010Applicant: QUALCOMM IncorporatedInventors: Guangming Carl Shi, Kuo-Chun Lee, Tom Chin, Isaac Ta-yan Siu

Patent number: 6516188Abstract: A method and apparatus for acquiring an emergency service from one or more candidate mobile radio communication systems. An attempt is made by the mobile radio unit to acquire normal non-emergency service. If the attempt of acquiring normal non-emergency services fails and the user needs to originate an emergency call, an emergency scan list containing one or more candidate mobile radio communication systems is scanned, and an attempt is made to acquire emergency service from one of these systems. The emergency scan list is different from the normal preferred roaming list stored in the mobile radio unit. Next, the invention originates an emergency call in accordance with the service acquired from the emergency scan list.Type: GrantFiled: November 22, 1999Date of Patent: February 4, 2003Assignee: Qualcomm IncorporatedInventors: Wen J.
