The present invention disclosed a unified communication system based on micro base station. The system includes: a micro base station subsystem, a landline telephone network subsystem, an office network subsystem and a communication switching subsystem. The communication switching subsystem receives a voice service request from the micro base station subsystem and the landline telephone network subsystem, sends the voice service request to the micro base station subsystem when a called user in the voice service request is a mobile communication intranet user, sends the voice service request to the landline telephone network subsystem when the called user in the voice service request is a landline telephone network user, receives a service request from the micro base station subsystem, and sends the service request to the office network subsystem.

A system and method for supporting a multi-participant voice conference call using PSTN and Internet networks is described. The method for supporting a multi-participant voice conference call includes receiving voice from a PSTN client. The method also includes receiving voice data from a moderator and from at least one remote client connected to the Internet. The method then proceeds to mix the voice data from the PSTN client with the voice data from the moderator into a first mixed voice data that is transmitted to the remote client that is connected to the Internet. The method also mixes the voice data from the moderator with the voice data from the remote client connected to the Internet into a second mixed voice data that is transmitted to the PSTN client.

A fax and print method includes steps of providing a first fax device, a second fax device and a portable communication device, allowing the first fax device to send a fax password and a document to the second fax device and a data message and a text message corresponded to the fax password to the portable communication device, allowing the portable communication device to receive the text message and the data message, allowing the second fax device to receive the fax password and the document, generating a wireless connection between the portable communication device and the second fax device, judging if the text message is matched with the fax password, and printing the document when the result of the judgement is True. Therefore, the risk of being stolen is reduced through a transmission without the internet. The user does not have to remember any password. The user experiences are enhanced.

A mobile application and a method are described for servicing a second line service (“SLS”) based communication request originating from a subscriber's telecommunications device (“TD”) even if the call signal does not include sufficient information to identify the phone number from which the subscriber initiated the call. The method involves associating the SLS phone number of the subscriber, the primary number of the subscriber and the primary number of a third party via a special relationship number.

A routing system is provided for intelligent routing of instant messages between clients connected to a data network and customer service representatives connected to the network. The system comprises at least one instant message server and at least one intermediate server connected to and addressable on the network, the intermediate server capable of routing and accessible to the instant message server. Clients connecting to the instant message server through instant message software assert a connection link advertised by the instant message server to establish bi-directional communication between the client machine and the intermediate server. In preferred application, the intermediate server interacts with the client for identification of client and client software. The client request is then routed to an appropriate customer service representative running compatible software according to enterprise rules establishing an active instant message connection between the client and the selected customer service representative.

A mobile device identifies multiple, different networks available to a client resident on the mobile device, and sends multiple registration messages to an outbound proxy over the multiple, different networks via first, second and third communication interfaces. The mobile device determines whether access has been lost to a first network of the multiple different networks, and sends an invite message via the second communication interface, based on the determination, for an outbound call via a second network of the multiple, different networks for routing the outbound call via the second network.

Responsive to detecting a call from a first user into a call system, a user identifier associated with the first user by the call and user information associated with the user identifier can be added to respective user information stored in an e-meeting data structure associated with the call. Responsive to determining the call system recognizes the voice of the first user, the first user can be identified based on the voice of the first user. Responsive to determining that the user information associated with the user identifier contains information not related to the identified first user, the information not related to the identified first user can be removed from the e-meeting data structure. An e-meeting for the call can be generated, the e-meeting including as participants the first user and at least a second user.

A differentiated routing system includes a computer-executable system to receive a request from a first network gateway of a native network for establishing a communication service from a calling party terminal to a called party terminal. Upon receipt of the request, the system determines that policy information is not known for the calling party terminal that has originated the request, and therefore append a tag to the request in which the tag indicates that the requested communication service is to be established using one or more generic policies. The generic policies include one or more default policies to be used for establishing the communication service. The system then transmits the request to a routing device, wherein the routing device determines how the communication service is routed through the native network according to the one or more generic policies.

A telecommunications addressing system/method allowing selection of a telephone instrument device (TID) using arbitrary identifiers is disclosed. The system/method allows a source TID (STD) to select a target TID (TTD) by the use of a Target Telephone Identifier (TTI) data string rather than a traditional numeric telephone identification (NTI). This TTI is then indexed within a TTI/NTI mapping server (TMS) that functions as a hierarchical repository of TTI/NTI mappings. STD/TTD communication is established by first performing a lookup of the STD-selected TTI within the TMS to identify the NTI of the TTD. Once the NTI of the STD has been identified by the TMS, communication between the STD and TTD is established using the NTI via the normal public switched telephone network (PSTN). TMS TTI lookup may be performed via STD TID web application and/or via PSTN infrastructure interface.

An enhanced Circuit Switch Fallback enabled Heterogeneous Network (HETNET) is provided by the present invention in which the 1×IWS functionality is co-located with LTB eNB. It also tunnels 1×RTT over LTE messages directly to the Convergence Server over SIP, Further, it enables distributed PN-FAP identification determination. A mobile management, entity is configured to maintain multiple 1×CS IWS tunnels. Multiple 1×CS IWS tunnels are established, by using the same S1 tunnel end point used in establishing a Borne evolved Node B Gateway of the HETNET. The HETNET is configured to provide a correct FAP identification to the convergence server so that handover preparation can be done.
