20080247523 | Multiple virtual telephones sharing a single physical address - A shared multi-user IP telephone device for receiving, based on SIP, calls transmitted over VoIP network, a system using such a device and method thereof. The shared multi-user IP telephone device includes a storage device for storing user profiles, an ID extraction portion for receiving from the VoIP network a SIP packet including at least the callee's ID, and extracting the ID contained in the SIP packet, and a personalized feature presentation portion for searching in the storage device for the user profile corresponding to the ID according to the extracted ID for presenting the corresponding personalized feature according to the search result. Thus it is possible for everyone using such a phone to receive directly the call for him/herself without anyone else or other device forwarding the call. | 10-09-2008 |
20090008445 | VIRTUAL MEMBERSHIP CARD SYSTEM AND PROVIDING METHOD, AND VIRTUAL MEMBERSHIP CARD READING METHOD - A method for providing virtual membership cards whereby by a card broker generates a virtual membership card based on the information of a card issuer and the information of a user and sends the virtual membership card to the mobile terminal of the user though a communication network. A virtual membership card system includes a membership management module, for managing card issuer account information, card user account information, and the virtual membership card information and a virtual membership card management module, including a card generation module, for generating a virtual membership card based on the information of the card issuer and the information of the user and a card distribution module, for sending the virtual membership card to the mobile terminal of the user though a communication network. With the present invention, merchants can easily issue, validate and maintain their membership cards, and the user may retrieve, use and manage his/her membership card at any place and at any time. | 01-08-2009 |
20090103451 | Method and system for topology discovery in an SIP network - A method for discovering topology in an SIP network is disclosed. According to the method, the SIP network is divided into domains governed by corresponding SIP proxies. A management system creates a topology agent for each SIP-domain and registers it with the governor proxy of each SIP-domain. Each topology agent generates topology-exploring messages to other agent and accumulates topology-exploring messages from other agents, gather routing information of the SIP network based on the collected topology-exploring messages to deduce topology of the SIP network. | 04-23-2009 |
20090122785 | VoIP ADAPTER, IP NETWORK DEVICE AND METHOD FOR PERFORMING ADVANCED VoIP FUNCTIONS - A VoIP adapter for POTS a phone comprises: a POTS phone connector, an IP network interface, two sets of signaling senders, signaling receivers, media senders and media receivers for the POTS phone and the IP network respectively, and a controller for controlling the operations of above components. The VoIP adapter enables the user to carry out VoIP communications using a normal POTS phone and further enables use of advanced VoIP functions via the normal POTS phone, such as Call Hold, Call Transfer, Ad Hoc Conference, etc. | 05-14-2009 |
20090270073 | AUTHENTICATING IDENTITY OF CALLER - A method, apparatus, system, and computer readable medium for authenticating the identity of a caller. An authentication device authenticates a caller's identity based on received information of the caller and an identifier generation device generates an identifier containing the caller's identity. The authentication information is supplied to a mobile telephone user acting as a callee. Therefore, the callee knows the caller's identity, thereby providing a secure delivering channel. | 10-29-2009 |
20100333200 | METHOD AND APPARATUS FOR SPAM MESSAGE DETECTION - A method, apparatus and computer program product for spam message detection. The method includes collecting time domain transmission characteristic of a message source; computing frequency domain transmission characteristic of the message source with the time domain transmission characteristic of the message source; and identifying the message source to be a spammer in response to the frequency domain transmission characteristic of the message source satisfying predefined criteria; wherein the steps of the method are carried out using a computer device. An apparatus and computer program product for carrying out the above method is also provided. | 12-30-2010 |
20110023116 | METHOD AND APPARATUS FOR SPAM SHORT MESSAGE DETECTION - A method and apparatus for spam short message detection. The method includes obtaining sending characteristics of at least two suspected short message sources, judging whether the two suspected short message sources have similar sending characteristics, and determining the two suspected short message sources as spammer if they have similar sending characteristics. A spammer that makes multiple short message sources send short messages alternately can be detected through similar sending characteristics of the short message sources. | 01-27-2011 |
20110289207 | METHOD AND APPARATUS FOR PROCESSING NETWORK VISUALIZATION - A method, system and computer program product for processing network visualization. The network visualization processing method includes: obtaining main-information-dimension-based topological data of an analytic object in a network; performing visualization processing to the main-information-dimension-based topological data of the analytic object so as to reveal change of a relationship between an analytic node and a neighboring node in the analytic object along the main information dimension. The network visualization processing method and apparatus according to the present invention can display dynamic change of the network based on main information dimension within a single view, and provide a better graphical resolution, so as to facilitate a user to perform analysis to the network and to reduce comprehension overhead of the user. | 11-24-2011 |
20120221232 | METHOD AND APPARATUS FOR TRAFFIC MANAGEMENT - A method for determining travel time of a vehicle on a road, wherein the vehicle is operable within a mobile communication network, comprising: collecting historical communication events of a mobile user in order to obtain travel samples, wherein the historical communication events indicate when the mobile user travelled along a monitored road; determining a cell handover sequence from the historical communication events; determining from the cell handover sequence, one of more road segments of the monitored road; determining the travel time of the one or more road segments according to the travel time samples; selecting, for an undetermined road segment of the monitored road for which the real-time travel time is not determined from the collected historical communication events, a candidate mobile user that is most likely to appear on the undetermined road segment; actively positioning the candidate mobile user to obtain positioning information; and returning to the step of collecting communication events of a mobile user currently on a monitored road with the active positioning as one communication event for the candidate mobile user, to determine the real-time travel time of the undetermined road segment. | 08-30-2012 |
