摘要： A mobile device is engaged in a connected data service via a wireless network. The connected data service utilizes a radio traffic channel established between the mobile device and the wireless network and a data session for communicating data. While engaged in the service, the mobile device receives via a user interface a voice call request for initiating a voice call. In response to the request, the mobile device permits the initiation of the voice call. Specifically, the mobile device causes the radio traffic channel for the connected data service to be torn down without terminating the data session. The mobile device also causes the voice call to be established and maintained over a new radio traffic channel via the wireless network while the data session for the data service is maintained.

摘要： A voice call request for a voice call involving the mobile device is received in a wireless network while the mobile device is engaged in a connected data communication service via the wireless network. The service utilizes a radio traffic channel between the mobile device and the wireless network and a data session for communication of data. In response to the receiving of the voice call request, the wireless network causes the radio traffic channel for the service to be torn down without terminating the data session. The wireless network also causes a voice call involving the mobile device to be established and maintained over a new radio traffic channel via the wireless network while the data session for the service is maintained. Subsequently, the wireless network identifies an indication that the voice call involving the mobile device has ended and, in response, resumes the communication of the data in the data session over a radio traffic channel.

摘要： A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed.

摘要： Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station.

摘要： A method for allowing a mobile station to find a code transmitted by a base station which has a propagation delay to the mobile station which is much larger or smaller than a propagation delay between the mobile station and a base station from which it derived a time reference is provided. In the context of IS-95, a PN offset is sent to the mobile station to identify which target base station pilot signals to search for. By sending a virtual PN offset which differs from the real PN offset, the mobile station can find the target base station signals where normally they would fall outside the mobile station's search window.

摘要： Methods and apparatus for prioritizing voice call requests during data communication sessions involving a mobile communication device are disclosed. In one illustrative example, an end user invokes a voice call request though a user interface of the mobile device. If this request is made while the mobile device is engaged in a connected data communication service, the mobile device immediately forces the connected data service into a dormant state. In particular, a release order is transmitted to tear down a traffic channel of the connected data service so that the voice call request can be processed. Subsequently, a voice call with the mobile device is established using a new traffic channel. When the voice call is completed, data communications will resume if needed. Advantageously, the mobile device prioritizes voice calls over data communication sessions which may be deemed less time-critical.
