Abstract: Systems and methods are provided for lawful interception of data transmissions through at least one broadband network. Data transmissions, including voice and data services as well as high bandwidth transmissions such as multimedia and video, are intercepted and routed to authorized agencies such as law enforcement monitoring facilities. The systems and methods also enable interception of data transmissions such as peer to peer type data transmissions that pass through broadband networks from source to recipient without passing through centralized core network elements. These transmissions are intercepted at access points distributed throughout the broadband networks and forwarded to lawful intercept node elements for transmission to authorized entities.

Abstract: Method for providing intercepted Content of Communications CC information from Intercepting Control Element ICE to at least one Law Enforcement Monitoring Facility LEMF through Delivery Functions in a telecommunications network, comprising the steps of: splitting the intercepted CC information into CC control information and CC payload information; at a Lawful Interception Content of Communications Control Point LI CC CP, receiving the CC control information and processing the CC control information; at an LI CC Gateway, receiving the CC payload information from the ICE over a payload interface X3, said LI CC Gateway being controlled by said LI CC CP according to said CC control information; and at said LI CC Gateway, switching the CC payload information to said at least one LEMF over a payload Handover Interface 3 HI3.

Abstract: Systems and methods for legal interception of the transmission of personalized ring back tones as they are sent from a network such as a mobile telephone network associated with a subscriber to a caller in response to a call placed by the caller to the subscriber to allow monitoring of personalized ring back tones and/or their associated call content data. The personalized ring back tone is intercepted at an intercept access point on the network, where the systems and methods of the invention then transmit the intercepted personalized ring back tone to an authorized person or entity, such as a law enforcement agency.

Abstract: The present invention relates to methods and arrangements to intercept Short Message Services (SMS) in a telecommunication system (TS). The telecommunication system comprises a telecommunication Network (PLMN-A) that comprises a Short Message Service Centre (SMSC; ICE, IAP) responsible for relaying Short Messages (SMs) to/from all subscribers belonging to the telecommunication network. The method comprises the following steps: Receiving in the Short Message Service Centre (SMSC), a request to monitor Short Messages (SMs) related to a subscriber (A, Al, B, C, D, E, F) in the telecommunication system (TS). Registering in the Short Message Service Centre (SMSC) a Short Message (SM) related to the monitored subscriber (A, Al, B, C, D, E, F). Delivering from the Short Message Service Centre (SMSC), information related to the registered Short Message.

Abstract: 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.

Abstract: A method of controlling paging flow in a network for cellular communications is described, which comprises the steps of: at a control node, receiving a request for paging a mobile station; determining a location area in which the paging shall be performed; checking whether the number of paging transactions which are ongoing for the location area is lower than at least one maximum number of ongoing paging transactions allowed for the location area; after a determination that the number of ongoing paging transactions is lower than the maximum number, updating the number of ongoing paging transactions for the location area and processing the paging request. Preferably, if the number of ongoing paging transactions is not lower than the maximum number, it is checked whether the paging request is a particular LCS transaction and, if so, the request is placed in a buffer and served with priority as soon as the number of ongoing paging transactions returns to be lower than the maximum number.

Abstract: The present invention relates to methods and arrangements in a telecommunication system to monitor telecommunication activities within a specified area, which system comprises an access Point ICE associated with a Configuration Unit ICU, which method comprises the following steps: Receiving to the Access Point ICE from the Configuration Unit ICU, a request 11 to monitor telecommunication activities related to all non-excluded telecommunication members MS within a defined area LA1. register in the Access Point ICE, a telecommunication activity related to a member MSB within the defined area LA1. establish, in the Access Point ICE, that the member MSB is a non-excluded member. delivering information IRI, CC related to the non-excluded member MSB, from the Access point ICE to the Configuration Unit ICU.

Abstract: The invention relates to the provision of deferred location reporting wherein the reporting is triggered by a trigger location change event. Trigger location change events are either related to a user of a cellular telecommunication network entering, leaving or changing an area, or to an area, which is entered or left by a user.

Abstract: A method is provided for positioning a target user equipment of a first subscriber within a network for cellular communications, the method comprising the steps of: at a service node connected to a GMLC, receiving a Mobile Originating Location Services invoke from a requesting User Equipment (UE) of a second subscriber, the invoke comprising a target identifier of the target UE; initiating a checking whether a requesting identifier associated with the requesting UE is comprised within a list of allowable identifiers of respective UEs which are allowed to position the target user equipment; and, in response to a determination that the requesting identifier is comprised within the list of allowable identifiers, positioning the target UE and returning location information resulting from the positioning to the requesting UE.

Abstract: The invention provides a method for the determination of a velocity of a user equipment by means of location services, wherein the velocity of a user equipment is calculated by a radio access network node.

Abstract: The invention relates to a method for distinguishing between LOCATION REPORT messages to avoid ambiguities. Therefore, a value of an information element of request type is returned by a radio network controller, depending on an intended receiver of the location information. A control node receiving the information element value analyses said value and determines the receiver depending on the result of said analysis.

Abstract: The invention relates to the provision of deferred location reporting wherein the reporting is triggered by a trigger location change event. Trigger location change events are either related to a user of a cellular telecommunication network entering, leaving or changing an area, or to an area, which is entered or left by a user.
