| 20100182507 | METHOD AND APPARATUS FOR USING A COLOR INDICATOR TO DISPLAY FREQUENCY OR CHANNEL SELECTION - A system for matching the currently tuned frequency of a signal transmitting device with that of a signal receiving device, including a transmitter having an illuminated color display which changes colors in relation to the channel or frequency on which the transmitter is currently tuned, and a signal receiving device having an illuminated color display which changes colors in relation to the channel or frequency on which the signal receiving unit is currently tuned. Each device has a channel selector function so that the frequency to which the device is tuned can be changed, thereby changing the color displayed. | 07-22-2010 |
| 20100315021 | CIRCUIT AND METHOD FOR CONTROLLING RGB LED COLOR BALANCE USING A VARIABLE BOOSTED SUPPLY VOLTAGE - A microprocessor uses one or more output pins to pulse width modulate a charge pump network to achieve a boosted voltage on an output port. The boosted voltage is then used to drive an LED, which may have a higher voltage drop than that of the starting un-boosted voltage. The adjustment of either the frequency or duty cycle of the PWM signal allows for adjustment of the steady state output voltage. This allows for the adjustment of the brightness of the LED by firmware while supplying enough voltage drop required by the LEDs. | 12-16-2010 |

| 20100099443 | SMS OVER WIRELESS PACKET DATA NETWORK - A system may include one or more network devices. The one or more network devices may receive a short message service (SMS) message intended for an access terminal, embed the SMS message into a data message, determine whether a data session exists with the access terminal, the data session occurring over a data network, transmit the data message to the access terminal via the data network when the data session exists, and transmit the SMS message via a voice network when the data session does not exist. | 04-22-2010 |
| 20100278125 | REDIRECTING A CALL BY A CIRCUIT SWITCHED NETWORK TO AN INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM (IMS) NETWORK - A device receives a call for a user device associated with an Internet protocol multimedia subsystem (IMS) network, where the call includes a mobile directory number (MDN) associated with the user device, and retrieves, from a home location register (HLR), an address of a wireless intelligent network (WIN) termination trigger service control point (SCP). The device sends, to the WIN termination trigger SCP, a first message that includes the MDN, receives, from the WIN termination trigger SCP, a second message that includes steering digits as a prefix to the MDN, and generates a third message that includes a called party number set to the MDN and omits the steering digits. The device also routes, based on the steering digits, the third message to a media gateway control function/media gateway (MGCF/MGW) of the IMS network, where the MGCF/MGW further processes the call. | 11-04-2010 |
| 20110093542 | SESSION INITIATION PROTOCOL (SIP) SIGNALING TO KEEP A VOICE OVER INTERNET PROTOCOL (VoIP) SESSION ACTIVE DURING A CALL HOLD - A device monitors a session description protocol (SDP) parameter associated with a voice over Internet protocol (VoIP) call provided via a network and a user equipment, and determines, based on the SDP parameter, whether the VoIP call changed from an active state to a hold state or from a hold state to an active state. The device also sends, after the VoIP call is determined to change from an active state to a hold state, a session initiation protocol (SIP) keep alive message to the user equipment to prevent the user equipment from entering a dormant state and to prevent a radio link connection between the user equipment and the network from being released. | 04-21-2011 |

The system includes a device that receives a lawful intercept request from a law enforcement agency, and determines whether a packet data lawful intercept or a SIP-based applications (SBA) lawful intercept is requested by the lawful intercept request. The device also provisions, when a packet data lawful intercept is requested by the lawful intercept request, a policy control and charging rules function (PCRF) and a packet data network (PDN) gateway (PGW) for the packet data lawful intercept. The device further provisions, when a SBA lawful intercept is requested, a proxy call session control function (P-CSCF), a serving-CSCF (S-CSCF), and a session border controller (SBC) for the SBA lawful intercept. | 06-16-2011 |
| 20110150196 | TELEPHONE NUMBER MAPPING - A method may include receiving a telephone number mapping query associated with a call from a calling party to a called party. The method may also include identifying, based on the query, first routing information that identifies a call session control component to process the call, and second routing information that identifies a border control component. The method may further include forwarding the first routing information to the querying device, and forwarding the second routing information to the querying device when the query originated from outside a network servicing the called party. | 06-23-2011 |
