Jun 23, 1999

Appl. No.:

09/339344

Inventors:

Ram Krishnan - San Diego CA
Johnny K. John - San Diego CA

Assignee:

Qualcomm, Incorporated - San Diego CA

International Classification:

H04B 138

US Classification:

455553, 455557

Abstract:

A switch (212) is included in a wireless terminal (206). Different settings of the switch cause a processor (210) in the wireless terminal to use different device algorithms. The switch itself is set by applying a code signal to the wireless terminal through its RJ-11 interface (208). The code is a sequence of Dual Tone Multiple Frequency (DTMF) tones, which may conveniently be provided by an ordinary telephone (214), or by a computer modem (204). A single wireless terminal may therefore be reconfigured on demand to interface with any of a variety of devices (202), (214).

International Classification:

H04Q007/20

US Classification:

455/432000, 455/433000

Abstract:

A mobile communication device, and a method of connecting a mobile device to a preferred communication system, are disclosed. The mobile communication device includes a signal sender, a signal receiver, and a processor and memory. The processor and memory include a static table, and are in communication with the signal sender and the signal receiver. The processor and memory match a location of the device directly to at least one preferred system. The mobile communication system includes at least one base station and the at least one mobile communication device. The method includes the step of locating of the mobile communication device, the step of converting the location generated into a position range, the step of matching the position range to at least one preferred SID index for the position range using a lookup table, the step of selecting the preferred SID from a roaming list, wherein the preferred SID is correspondent to the at least one preferred SID index, and the step of connecting the mobile communication device to a channel correspondent to the preferred system indicated by the preferred SID.

International Classification:

H04W 8/20
H04L 29/12
H04L 29/08
H04L 29/06

Abstract:

In an embodiment, a client device (CD) maintains a contact profile for a user of the CD, the contact profile including a universal identifier (UID) for the user and a list of devices and addresses at which the user of the CD can be contacted. The CD establishes a communication session with a remote CD (RCD) via a given contact address from the set of contact addresses for the RCD. The CD shares, in response to the communication session establishment, at least a portion of the contact profile to the RCD. The RCD generates and/or updates a given contact profile for the user of the CD that is maintained on the RCD based on the shared contact profile. The RCD can also share its profile with the CD in response to the communication session establishment, causing the CD to generate and/or update a contact profile for the RCD.

International Classification:

H04W 28/24

US Classification:

370259

Abstract:

In an embodiment, a Voice over Internet Protocol (VoIP) bidder negotiates with a VoIP provider and/or a VoIP access network to establish the VoIP provider as a preferred or default VoIP provider for the VoIP access network (e.g., a set of particular WiFi APs, a non-roaming cellular access network, etc.). As the preferred or default VoIP provider, the VoIP access network gives preferential performance and/or contract terms (or VoIP opportunities) for providing VoIP service to user equipments (UEs) via the VoIP provider as compared to one or more other VoIP providers that are also configured to provide VoIP service to the UEs over the VoIP access network. In a further embodiment, one of the UEs connects to the VoIP access network and advertises, to a user of the UE, the preferential performance and/or contract terms available to the UE via the VoIP provider over the VoIP access network.

Abstract:

Aspects for enhancing call control for directing a content path over multiple connections may include a method which includes establishing a first connection to a destination to use as a content path, receiving information from the destination for establishing an alternative connection, establishing as the alternative connection a background connection to the destination based on the information received, evaluating whether the background connection is preferable to the first connection for use as the content path, and switching the content path to the background connection when the background connection is preferable. Another method may include establishing a first connection as a content path and a background connection simultaneously to a destination for exchanging call traffic representing the same content, evaluating whether the background connection is preferable to the first connection for use as the content path, and switching the content path to the background connection when the background connection is preferable.
