Abstract:
A spam filtering system based on SIP(Session Initiation Protocol) using a spam detection part and a spam filtering part and a method thereof are provided to minimize damage by telephony spam on SIP network due to filtering the spam according to a spam countermeasure by analyzing the SIP message transmitted for a call session connection. A spam detection part(15aa) receives an SIP message in which the labeling is completed from an outgoing side user agent(14). The spam detection part detects spam through the label within the received SIP message. A spam confirmation part(15ab) confirms the received SIP message by the call receiver. The spam confirmation part confirms a spam countermeasure corresponding to a caller through a spam managing server. A spam filtering part(15ac) filters the spam according to the spam countermeasure.

Abstract:
A method of transmitting and receiving a data frame supporting a video MAC protocol and a system thereof are provided to use contents having error partially, thereby reducing waste of network resources due to contents retransmission. A video MAC(Media Access Control) support terminal determines whether a video MAC protocol is supported(S210). A video MAC data frame is received so that the video MAC support terminal determines whether error exists in a header. If the error does not exist in the header, the received video MAC data frame is provided to a user without respect to that error exists in a body(S240).
Abstract:
An apparatus and a method for coping with IP(Internet Protocol) multimedia spam in an Internet protocol multimedia service providing network are provided to construct an expanded IP multimedia application server having no relation with an application layer or a service type of sub-network to cope with spam. An apparatus for coping with IP(Internet Protocol) multimedia spam in an Internet protocol multimedia service providing network includes a service broker(110) for classifying all calls by application services, a spam controller(131) for exchanging policy and database information differently applied by the application services to perform security management and verifying whether each of all the calls classified by the service broker has spam, a policy and database management interface(140) for transmitting a policy to the spam controller, and a resource manager(160) for managing resources required for the spam controller.
