Assignee:

SBC Technology Resources, Inc. - Austin TX

International Classification:

H04M011/00

US Classification:

455406, 455408, 379230, 37911401

Abstract:

A service control point transmits a recharge request message or advice of charge to a mobile client resident in a wireless communications device. The message is first received by a wireless telephony application server that then forwards the message to a wireless access protocol gateway. The wireless access protocol gateway then sends the request to the mobile client. The user of the mobile client responds with an affirmative or negative answer to the request to recharge the prepaid telephone airtime account. The service control point then either recharges the account as instructed or lets the account expire, depending on the response from the user.

US Classification:

709248, 709204, 709249, 709205, 455466, 455414

Abstract:

Wireless access protocol-capable wireless devices are able to synchronize displayed Web content. A first WAP device requests a synchronized session through the sync Proxy of the network. The sync Proxy, through a WAP Push Proxy, sets up the synchronized session. One or both wireless devices may then request content from a Web site. This content is transmitted from the Web site to the first device, and through a WAP proxy to the second device.

International Classification:

G06F 3/00

US Classification:

719315, 719313, 719316

Abstract:

A user agent in a Web access device transmits an HTTP request for Web content to an origin server. The request contains a set of capabilities of the Web access device. A content authoring mechanism and adaptation determination service on the origin server process the request to determine what transformation is required to make the requested content fit the capabilities of the Web access device. The adaptation determination service invokes a niche transformation service that performs, in response to the content and the capabilities, the necessary transformation. The transformed Web content is transmitted to the user agent.

Assignee:

SBC Properties, L.P. - Reno NV

International Classification:

H04Q 7/20

US Classification:

4554565, 4554562

Abstract:

A plurality of wireless network access points (NAPs) each having a known location are provided. The wireless NAPs comprise shorter-range NAPs and longer-range NAPs. An associated precedence is assigned to each of the NAPs. A history database is to track a sequence of the NAPs accessed by a wireless device in a session. If a request for information from the wireless device is received by at least two of the NAPs, a processor determines which of the at least two NAPs has a greatest precedence and assigns same as a current NAP. The processor estimates a current location of the wireless device based on the known location of the current NAP and the known location of a previously-current NAP for the wireless device from the history database.

International Classification:

G06Q 30/00

US Classification:

705 26

Abstract:

One or more content providers push data related to: movies, movie products, digital movie content over a network (e. g. , a LAN, a WAN, the Internet, or a wireless network) onto an information filling station which, in turn, wirelessly transacts (over a network based on the 802. 11protocol) and transmits any requested data to a portable computer-based device (e. g. , laptop, a pen-based computer device, a PDA, a wireless phone, or a pager). The portable device performs financial transactions for: purchasing movie tickets (directly or via auctions), downloading digital entertainment content of interest (e. g. , copy of a movie of interest, copy of a movie identified based on a pre-stored profile, copy of soundtrack of a movie of interest), or movie related products. Any purchased digital content is either transferred wirelessly onto the portable device or, optionally, sent on a storage medium to a physical address associated with the profile.

Abstract:

Via a user interface, a user creates a device group that identifies communication devices of the user, the devices having different communication addresses. At least one of the devices is user-designated to receive an aggregated list of communications made with the devices in the user-defined device group. Communications made using devices in the group are detected, entries for the aggregated list are generated based thereon, and the entries are provided to the designated communication device(s). Thereafter, the user edits the user-defined device group via the user interface to add a communication device thereto or to remove a communication device therefrom.
