Abstract:
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.
Abstract:
Methods and apparatus for communicating with a multimode mobile station supporting multiple radio access technologies (RATs) are provided. For certain embodiments, when a paging request is received via a first RAT network, paging requests may be broadcast on all RATs supported by the mobile device. As a result, the mobile device may receive the paging request regardless of which RAT it used for a current network connection.
Abstract:
The invention relates to a mobile station apparatus in a communication system. The communication system comprises a plurality of base stations for providing mobile communication service within a covered communication area. The mobile station apparatus comprises a memory for recording a predetermined access control class and determining which base station the mobile station apparatus is allowed to camp on for conducting mobile communication service, a battery for providing electrical power, a control program, and a power detector for detecting the current power of the battery, so that when the power detector detects that the power is lower than a predetermined low power watermark, the power detector issues a trigger signal. When the control program receives the trigger signal, the control program overwrites the predetermined access control class, so as to allow the mobile station apparatus to conduct mobile communication service through other base stations in the communication area.
Abstract:
Call processing system and method for mobile users. The processing system identifies call urgency by categorizing incoming emergency data calls, and prioritizes the data calls accordingly. The emergency call processing method comprises submitting a data call to an emergency call center, placing the data call in a queuing system according to the priority level of the emergency, and waiting for an available processing unit to call back and address the emergency. During the waiting period, the emergency call center solicits information associated with the emergency, and user equipment returns the requested information automatically. The present invention improves efficiency of the emergency call center, ensuring that the most urgent emergency is served first. Additionally, the present invention conserves battery power of user equipment by collecting relevant information beforehand using data messages.
Abstract:
A method for proceeding with communications by a mobile device is provided. The method first determines if any registered public land mobile network has been stored in the mobile device. If yes, the method determines if the signals from the registered public land mobile network are clear enough to maintain a good communication quality. If yes, the method determines if the mobile device is one legitimate user of the registered public land mobile network. If yes, the mobile device starts to transmit signals via the registered public land mobile network.
