A system and method are provided for controlling communications privacy in a Home Network telephone system. The method comprises: using a gateway to send and receive calls on at least one external telephone line; supplying privacy and public mode bridging options; and, selectively excluding bridges between external telephone lines and a plurality of Home Network endpoints. In response to the privacy mode being selected, the gateway bridges a call between a first external telephone line and a first endpoint, and prevents bridges between the first external telephone line and other endpoints in the system. Alternately, when the public mode is selected, the gateway bridges a call between the first external telephone line and the first endpoint; and permits bridges between the first external telephone line and other endpoints in the system. That is, while the call is bridged to the first endpoint, a bridge is added between the first telephone line and the second endpoint. The privacy and public mode bridging options are selected with respect to nodes. A node can be an external telephone line or an endpoint. That is, a privacy or public mode of operation can be selected for a first external telephone line, whether calls are received or originated through the Home Network telephone system. Likewise, a privacy or public mode of operation can be selected for a particular endpoint, regardless of whether the endpoint receives or originates the call.

The present invention provides a method for delivering an advertisement to a user comprising providing an advertisement by the advertiser to the service system, followed by delivering the advertisement by the service system to a mobile phone of a user through mobile phone communication network. The user determines to browse the advertisement or not. The user watches and brows the advertisement via the display of the mobile phone.

A method for screening and routing incoming telephone calls includes extracting caller identification information from an incoming telephone call, providing a plurality of tables including a primary ring table, a secondary ring table, a voicemail table, a block call table, and a forward call table, and determining which one of the plurality of tables includes the caller identification information. The method also includes allowing the incoming telephone call to have a primary ring tone if the primary ring table includes the caller identification information, and allowing the incoming telephone call to have a secondary ring tone if the secondary ring table includes the caller identification information. The method further includes sending the incoming telephone call directly to voicemail without having a ring tone if the voicemail table includes the caller identification information, blocking the incoming telephone call if the block call table includes the caller identification information, and forwarding the incoming telephone call if the forward call table includes the caller identification information.

A security system capable of safely performing home device state check or operation. In the security system, a mobile telephone module of a mobile telephone transmits M-series data (call signal) to home device modules provided in home devices such as a door lock and home electric appliances. In response to this call, the home device module returns a home device ID to the mobile telephone module. The mobile telephone module authenticates the home device module according to the home device ID and after authentication, returns a mobile telephone ID and state check or operation command to the home device module. The home device module authenticates the mobile telephone module according to the mobile telephone ID. When this mutual authentication is complete, the home device module performs the home device state check or operation according to the command and returns the result to the mobile telephone module. Thus, the state check or operation is performed after mutual authentication and it is possible to prevent an unauthorized access of a third person.

A system and method for communicating via a packet telephony distribution system is defined that includes a dual-use / analog phone or phone adapter. Any communication device incorporating the adapter can dynamically receive incoming calls and transmit outgoing calls over analog phone lines and over derived phone lines such as VoIP (Voice Over IP). When receiving or transmitting calls, the adapter and an associated gateway perform operations that enable simultaneous communication over the analog phone lines or derived phone lines from any combination of communication devices. In cooperation with the communication devices, the gateway further dynamically controls the incoming and outgoing calls over the analog phone lines and derived phone lines.

The invention concerns a communication device (102) and a method (200) for providing a personalized ring-back to a first user of the first communication device (102), when the first user initiates a phone call with a second user of a second communication device (104). In one arrangement, the method can include the steps of detecting (204) reception of a ring-back signal at the first communication device (102) received from a communication network (108), retrieving (206) a multimedia file in the first communication device (102), and playing (208) the multimedia file in the first communication device (102) for at least the duration of the ring-back signal.

A portable terminal includes an output device configured to output a ringing tone, a vibrator configured to generate vibration, and a first controller configured to detect a missed call indicating that an incoming call response operation is not performed, and a second controller coupled to the first controller. The second controller is configured, if the first controller detects the missed call, to notify a missed call notification at predetermined time intervals by at least one of the ringing tone output from the output device and the vibration generated by the vibrator, the missed call notification indicating that a response operation for the missed call is not performed.

A technique for joint detection of channel-coded signals in a multiple-input multiple-output system includes detecting, when a decoded signal associated with a first symbol stream passes a cyclic redundancy check, channel-coded signals in the first symbol stream and a second symbol stream using minimum mean squared error with ordered successive interference cancellation (MMSE-OSIC) based detection. When the decoded signal associated with the first symbol stream fails the cyclic redundancy check, the channel-coded signals in the first and second symbol streams are detected using neighbor search algorithm (NSA) based detection.

A device for intelligently adjusting a volume level for call / message alerts includes a processor, an interface(s), a memory, a timer and a volume adjuster. The processor receives a call(s) / message(s) and causes the memory to store data associated with the call(s) / message(s). The processor invokes a timer and instructs a ringer to generate a call / message alert. The processor receives an additional call(s) / message(s) and determines if these calls / messages are sent from the same user of an electronic device as a previous call / message within a time period. If a previous call / message was missed by a user of a terminal, the processor causes a ringer to increase the volume of a subsequent call / message sent from the user of the electronic device. If a previous call / message was rejected by a user of a terminal, the processor causes the ringer to decrease the volume of a subsequent call / message sent from the user of the electronic device.

Basic matrix based on irregular LDPC codes, codec and generation method thereof. The codec includes an encoding / decoding operation module and a basic matrix storage module. In the stored basic matrix Hb, for all girths with length of 4, any element of i, j, k or l constituting the girths in anti-clockwise or clockwise always satisfies inequality: mod(i−j+k−l, z)≠0, wherein z is the extension factor. When generating the basic matrix, firstly the number of rows M, number of columns N, and weight vectors of the rows and columns are determined, an irregularly original basic matrix is constructed; then the position of ‘1’ is filled by a value chosen from set {0, 1, 2, . . . , z−1} to obtain the basic matrix Hb, which is made to satisfy the above-mentioned inequality. The basic matrix Hb obtained by storing, which is configured with corresponding encoding / decoding operation module, constitutes the desired encoder / decoder. The encoder / decoder according to the present invention can effectively eliminate error-floor phenomenon of LDPC codes and accelerate the falling speed of BER curve.
