Abstract: A method and system for selecting a Multimedia Resource Function Controller (MRFC) for allocating resources for a conference call based on a pre-defined condition. In a first embodiment, the condition is associated with a status of an MRFC of a first network, such as an overload of resources, a failure, or an inexistence of the MRFC in the first network. When the condition is detected, an application server (AS) of the first network delegates the responsibility of allocating the resources for the conference call to an MRFC of a second network. In a second embodiment, the pre-defined condition is associated with a location of a User Equipment (UE) involved in the conference call. Based on the UE's location, the AS of the first network selects an MRFC of a second network, and delegates the responsibility of allocating the resources for the conference call to the MRFC of the second network.

The wireless receiving apparatus includes an integral computing unit for sequentially computing integrals of the signal levels of the tones of the tone signal at first predetermined time intervals and a data information computing unit for sequentially computing differences between two respective integrals of the signal levels of the tones of the tone signal, at respective second predetermined time intervals to acquire data information.

Abstract: Telephone numbers are omitted from a communications device (200) or line (110b), thereby inhibiting incoming calls. Outgoing calls are permitted on the line or communications device and are facilitated in part by an equipment identifier (122b, 222) used in a telecommunications network. A surrogate telephone number, which may already be assigned to a customer, is used for billing, caller identification and other functions. The equipment identifier is used for maintenance, administration and other functions associated with the communications device or line. A telephone number is temporarily made available to the communications device or line for a predetermined period of time upon request by a user. This advantageously reduces the number of telephone numbers required in a telecommunications network.

Abstract: A method is provided for enabling a customer to activate a call waiting feature for a list of caller numbers specified by the user. Calls from numbers on the list generate call waiting tones if they call while the customer is talking to someone. Other callers will hear a busy signal or may be routed to voicemail. The customer can activate the feature and add numbers to, or can remove numbers from, the list by entering one or more codes and interacting with prompts from a network server to enter the numbers to be added or deleted. A method for administering the feature on the network can include administering user charges for activating and maintaining the feature and deleting a number from the list when the user receives a call from the number.

Abstract: A user calls a directory assistance service provider to search for a desired telephone number and be connected to a party at the desired number. In one such connection, the user is afforded enhanced directory assistance upon a user command in the form of an out-of-band signaling message, e.g., SS7 signaling message. For example, the user may be afforded further operator assistance by pressing on the user telephone a predetermined key (e.g., “*” key), which is detectable by the directory assistance service provider as an SS7 signaling message.

Abstract: A network monitoring agent is disclosed that monitors network conditions, such as traffic volume, and determines when to dynamically adjust the encoding scheme for one or more connections. The network monitoring agent can select an encoding standard based on, for example, current network traffic volume, network error characteristics, time of day or day of week. In the illustrative network traffic implementation, an encoding standard that provides a lower degree of compression and a higher quality level is selected at times of lighter network traffic. Likewise, as network traffic increases, an encoding standard that provides a higher degree of compression, although at a lower quality level, is selected in order to maximize the network utilization. The network monitoring agent notifies one or both of the devices associated with each connection of changes in the encoding scheme. Generally, both devices must change the compression algorithm at the same time, to ensure proper decoding of received packets.

Abstract: Peak detector 104 detects the first peak timing where the correlation value of the first synchronization channel is the greatest. SSCH identifier 108 identifies the second synchronization channels by adding the correlation values of the second synchronization channels at a number of timings, and detects the timing where the sum of the correlation values of the identified second synchronization channels is the largest as a second peak timing. Based on the first and second peak timings, timing controller 105 instructs SSCH identifier 108 on the timing to perform correlation calculation. Likewise, based on the first and second peak timings, frequency corrector 110 calculates the error in a frame time measured by a base station, and converts this into a frequency difference, and changes the frequency of an oscillator in RF receiver 102 in such a way that corrects the frequency difference.

Abstract: To address the scarcity of radio frequency (RF) spectrum, the disclosed systems offer unique ways to mitigate interference between television broadcasters (including their direct audience and viewers served via cable television) and other concurrent users of the RF spectrum, e.g. for one-way or two-way wireless communication. A preferred embodiment makes use of the “framing” characteristics of the “letterbox” video display format. RF emissions of the simultaneous RF spectrum user are keyed “on” only or substantially only during the time intervals when the blanking intervals and/or letterbox-border video lines are being scanned on the display, i.e. when the potentially affected (interfered with) television display is in the letterbox-frame-scanning portions of each video field. The concurrent uses may support services for voice (including telephony, music etc.), data (including Internet, intranet, etc.
