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.

Methods and apparatus for service provisioning in wireless communication networks

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.

Quick system selection and acquisition for multi-mode mobile devices

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.

Methods and systems for improving response message transmission reliability

Certain embodiments of the present disclosure allow a mobile station to activate a sleep mode in order to reduce power consumption when the residual battery capacity is low. Certain embodiments of the present disclosure also provide techniques for adaptive power saving applied during an idle mode operation.

Methods and systems to prolong mobile station operation during low battery power

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.

Methods and apparatus for facilitating dynamic service-based system selection and determination

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.

Methods and apparatus for changing paging parameters in a communication system

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.
