.[.Anonymous voice communication between a first station and a second station is facilitated by providing an interface that allows input of a transaction specification from at least one of the first and second stations. A reference code associated with the transaction is generated, there being a defined relationship between the reference code and the address of the second station for voice communication. The reference code is supplied to the first station, and a voice communication request and the reference code are received from the first station. The reference code is used to recover said address and a channel for voice communication is opened between said first and second stations. Voice communication can thereby be established between the first and second stations without providing the address of the second station to the first station..]..Iadd.An Internet-based service system for data mining user information is herein disclosed and enabled. The disclosed service system may facilitate users posting information, advertising products/services, connecting to other users, and making transactions over the Internet. Data obtained from each transaction submitted through the service are data mined. The collected data may include personal information, private data, interests, intellectual property, etc. To create transactions, the system may create a proposed transaction specifying a transaction between first and second parties based, at least in part, on data mining the first and second party's history of transactions. The service system may transmit a reference code to the first party related to the proposed transaction, and wait to receive a communication request from the first party employing the reference code. The reference code may include text, image(s), video(s), audio, or communication link(s), and the proposed transaction may be an advertisement or matching service..Iaddend.

Disclosed embodiments provide improved communication between a caller and multiple parties. A caller performs a call spray operation on a group of contacts using an electronic communication device such as a mobile telephone. The call spray operation attempts to contact an electronic device associated with each contact in the group of contacts. If one of the contacts answers and is deemed to be a live user, then the remaining contacts that did not answer each receive a message on their associated electronic device indicating which of the contacts answered the caller with a live user. In this way, a group of people can be conveniently contacted and kept up to date with the status of the communication with the caller.

Aspects of the disclosure relate to apparatus and methods of event scheduling and notification. According to one aspect, a method, operational at a server, may include determining that a prescheduled event is concluded, sending a first notification message to one or more user communication addresses associated with the prescheduled event, determining if a first acknowledgement to the first notification message is received before a first predetermined period of time elapses, and sending a second notification message to the one or more user communication addresses if the first acknowledgement is not received by expiration of the first predetermined period of time. The method may further include determining if a second acknowledgment to the second notification message is received before a second predetermined period of time elapses and sending a third notification message to the communication addresses and a first alternate contact notification message to an alternate contact communication address.

Disclosed are an emergency call-for-help method and system based on fingerprint identification for a mobile terminal, and a mobile terminal. When a user is in an emergency, a mobile terminal sends an emergency short message including positional information to emergency contacts, and automatically calls the numbers of all the emergency contacts, so as to rapidly send a call-for-help signal to the outside world, thereby guaranteeing the user's safety, reducing safety risks and being convenient for the user.

.[.Anonymous voice communication between a first station and a second station is facilitated by providing an interface that allows input of a transaction specification from at least one of the first and second stations. A reference code associated with the transaction is generated, there being a defined relationship between the reference code and the address of the second station for voice communication. The reference code is supplied to the first station, and a voice communication request and the reference code are received from the first station. The reference code is used to recover said address and a channel for voice communication is opened between said first and second stations. Voice communication can thereby be established between the first and second stations without providing the address of the second station to the first station..]. .Iadd.Client (e.g., a device, a station, or an application) for accessing an Internet-based service that data mines user information is herein disclosed and enabled. The service may facilitate a user of the client connecting to other users over the Internet. Data obtained from each transaction submitted through the service are data mined. The collected or obtained data may include private data, interests, intellectual property, and the like. The client may (1) provide, to the user, a proposed transaction specifying a transaction between the user and another user, which is based, at least in part, on data mining the user's history of transactions; (2) provide a reference code to the user related to the proposed transaction; and (3) receive a communication request from the user employing the reference code. The reference code may include text, image(s), video(s), audio, or communication link(s), and the proposed transaction may include an advertisement..Iaddend.
