摘要:
A system, method, and gateway in a telecommunication network for providing intercepted Content of Communications (CC) information from an Intercepting Control Element (ICE) to a Law Enforcement Monitoring Facility (LEMF). The system splits the intercepted CC information into CC control and CC payload information. A control point receives the control information and controls the gateway in accordance with the control information. The gateway receives the payload information and routes it to the LEMF over a payload Handover Interface.

The present invention relates to methods and arrangements in a telecommunication system to override current access rights. The telecommunication system comprises an Access Point IAP; MSC, SGSN associated with a Configuration Unit ICU. The method comprises receiving to the Access Point IAP; MSC, SGSN from the Configuration Unit ICU, a request to monitor a system member MS, SIM. The method further comprises receiving to the Access Point from the Configuration Unit, a request to override deprived access rights for the system member MS, SIM. The method further comprises overriding in the Access Point IAP; MSC, SGSN, the deprived access rights for the member.

The present invention relates to methods and arrangements to perform monitoring-continuity in case of number portability in a telecommunication system. The method comprises a step wherein a monitored user (B) requires number portability from an operator of a donor network (DNW) to an operator of a recipient network (RNW). The method further comprises the receiving of a number portability event—temporary address (NPE1) to an agency controlled receiving entity (LEMF, ADRS), which event (NPE1) comprises information related to the user's ported identity and the user's new identity.

A control device (104) for controlling communication in an Internet Protocol Multimedia Subsystem IMS (150) coupling a user equipment (160, 162, 164) and an application provider (170, 172, 174) providing an application, the control device (104) comprising a receiving unit (190) adapted for receiving location information indicative of a location of the user equipment (160, 162, 164), a verification unit (192) adapted for verifying if the received location information matches a spatial area and a spatial condition in relation to the spatial area, wherein the spatial area and the spatial condition are part of a control criterion being associated with the application of the application provider (170, 172, 174), and a control unit (194) adapted for controlling a provisioning of the application to the user equipment (160, 162, 164) according to a result of the verification unit (192).
摘要:
The method provides a Law Enforcement Agency LEA with retention or interception data related to a target user. At a data retention source node or at an interception control element of a telecommunications network, traffic packets involving the target user are inspected and a plurality of usage data records based on the inspected traffic packets are generated. Each record comprises information relating to a certain service class and to a respective communications stack layer. For each communications session involving a plurality of different communications stack layers, at the data retention source node or, respectively, the interception control element, the plurality of usage data records are provided with a same correlation identity number for correlating the data at the different communications stack layers. Then, the usage data records comprising the correlation identity number to the LEA are sent, for instance to the LI system or the data Retention System, respectively.
摘要:
A method in a telecommunication system for monitoring a communication by a Law Enforcement Monitoring Facility (LEMF). The LEMF sends a request for monitoring of a first party to a Call Session Control Function (CSCF) in a service domain of the telecommunication system. When the CSCF detects a SIP session event due to a setup of a media-flow connection between the monitored party and a second party, the CSCF sends Interception Related Information (IRI) toward the LEMF, and sends a resource setup message to a Multimedia Resource Function (MRF), also in the service domain. A Gateway GPRS Support Node (GGSN) routes the Communication Content (CC) to the MRF. The MRF copies the CC and routes one copy back to the GGSN and routes the other copy to the LEMF via a Delivery Function utilizing a SIP session with the LEMF.
摘要:
The present invention relates to a method for monitoring in a telecommunication system. The system comprises a service domain that handles session control and a bearer domain used for transportation of media flow. A request for monitoring of a first party (A) is received by a Call Session Control Function (CSCF) in the service domain. The method comprises the following further steps: —A SIP session event is detected by the Call 10 Session Control Function (CSCF) due to a set-up of a media-flow connection between the monitored party (A) and a second party (B). —A resource set-up message (SIP1) is sent via an interface (Mr) from the Call Session Control Function (CSCF) to a Multimedia Resource Function (MRF) in the service domain. —A SIP transaction is established between the Multimedia Resource Function (MRF) and a third Delivery Function (DF3). —A SIP session is established between the third Delivery Function (DF3) and a Law Enforcement Monitoring Facility (LEMF).

The present invention relates to methods in a telecommunication system to provide access to data received to a centralized storage medium from interfacing traffic nodes in the system. The centralized storage medium is part of a Mediation and Delivery Function which is associated with a Law Enforcement Monitoring facility. The method comprises the following steps: Identifying in the Mediation and Delivery Function, a configuration request which comprises a filtering criteria specifying type of data to be accessed. Configuring in the Mediation and Delivery Function, the requested filtering criteria. Receiving data from the system to the centralized storage medium. Establishing that the received data matches the filtering criteria. Retaining the received data in the centralized storage medium and/or forwarding the data to the Law Enforcement Monitoring Facility.

The present invention relates to problems how to generate information related to use of a Cashless Calling Service Subscription. The problems are solved by methods and arrangements in a communication system to generate information related to use of the monitored Cashless Calling Service Subscription. The system provides the information to an Intercept Configuration Unit. The information is collected from the Interception Access Point that is associated to the monitored Cashless Calling Service Subscription. The method comprises the following step: receiving to the Interception Access Point a request to monitor the Cashless Calling Service Subscription number, detection of use of the monitored Cashless Calling Service Subscription number at the Interception Access Point, delivering information related to said use, from the Interception Access Point to the Intercept Configuration Unit.
