20090097419 | COMMUNICATION NODE, AND TOKEN ISSUING METHOD AND TOKEN-RING COMMUNICATION METHOD IN RING COMMUNICATION SYSTEM - A communication node includes a token-start-right acquisition processor that issues a token-start-right acquisition frame containing specific information, determines a priority based on predetermined reference using specific information for other communication node and the specific information for the own communication node upon reception of a token-start-right acquisition frame from the other communication node, issues the token-start-right acquisition frame at a predetermined time interval when the own communication node has a higher priority than the other communication node, and stops issuing the token-start-right acquisition frame when the own communication node has a lower priority than the other communication node, to forward the token-start-right acquisition frame of the other communication node, and also includes a token start processor that passes the token frame to the ring upon reception of the token-start-right acquisition frame which is issued by the token-start-right acquisition processor and circulates around the ring. | 2009-04-16 |
20090097420 | METHOD AND SYSTEM FOR LAWFUL INTERCEPTION OF VALUE-ADDED SERVICE IN IP MULTIMEDIA SUBSYSTEM - A method and a system for lawfully intercepting a value-added service in an IP multimedia subsystem (IMS) are provided. In the present method, a service subscription information is sent to a first information delivery module when a suspect is registered to an IMS network. A service triggering information is sent to the first information delivery module when the value-added service subscribed by the suspect is triggered. Furthermore, when the value-added service is provided, an intercept related information (IRI) is sent to the first information delivery module according to the characteristics of the value-added service. As a result, the suspect who is using the value-added service in the IMS can be lawfully intercepted according to the information collected by the first information delivery module. | 2009-04-16 |
20090097421 | IP-based interworking methods and apparatus for voice and data communications - Method and apparatus for call interworking between user equipments (UEs) located in domain using different communication protocols. The methods and apparatus receive a call request for establishing a call between a first UE and a second UE, the call request including a list of addresses corresponding to the second UE. A list of list of addresses corresponding to the first UE is then retrieved and a forking operation is performed the received list of addresses corresponding to the second UE. Then a determination is made, based on a set of rules, on which address to be used from the list of addresses corresponding to the first UE and which address to be used from the list of addresses corresponding to the second UE for establishing the call between the first UE and the second UE. | 2009-04-16 |
20090097422 | METHOD FOR SCHEDULING SIMULTANEOUSLY TERMINALS IN A COMMON FREQUENCY BAND, AND CORRESPONDING BASE STATION - The present invention relates to a method for scheduling simultaneously terminals belonging to two radio communication systems in a common frequency band, a base station of said first communication system having knowledge of said second radio communication system, both systems using an OFDM resource allocation mechanism on the air interface, an OFDM frame structure being predefined for said first system. According to the present invention, the method comprises the steps of: detecting in said first system the amount of resources needed for said second system for a predefined time period; determining a first part of said OFDM frame reserved for said first system and a second part of said OFDM frame reserved for said second system for said predefined time period, said first and second part of said OFDM frame being separated in the frequency domain of and taking into account the resources needed for said second system. | 2009-04-16 |
