摘要:
The present invention relates to methods and arrangements for monitoring translation activities in an intermediate node NAT/PAT between a local network and a public network in a communication system. The intermediate node NAT/PAT rewrites addresses related to traffic sent between the networks. The method comprises steps of configuring the intermediate node NAT/PAT to operate as Intercepting Control Element ICE or Data Retention source, and steps of requesting translation information, and reporting translation information to a requesting authority.

The present invention relates to a method for handling response times in a communication system comprising at least one data retention system (2;2,22,23) having at least one storage space (6A, 6B, 6C) for retained data. The at least one storage space (6A, 6B, 6C) has a defined response time (high, medium, low) for delivering retained data. The method comprises the following steps:—Receiving (31) a request for retained data from an authorized organization (3) to the at least one data retention system (2;2,22,23), which request comprises a specified data type and a retention time range—Dividing (37) in the at least one data retention system, the received retention time range into a least one time segment each corresponding to one defined response time (high, medium, low).—Delivering (32) an acknowledge message from the at least one data retention system to the authorized organization, which message comprises response and identification information corresponding to the at least one divided time segment.

A validation method for validating IP information header in data packets from user equipment connected to a mobile telecommunications network (1) and accessing an IP network (5) through a proxy. In the method trusted location information of the user equipment (2) from a trusted source of the telecommunications network is requested (109). Then, the trusted location information is inserted into the IP information header of a message (112) to be sent to a location based function (17).
摘要:
Systems and methods for legal interception of a transmission through a land based network to or from a mobile station based at least in part on the satisfaction of spatial criteria whereby a geographic area is identified and the location of one or more mobile stations is determined. Transmissions to or from one or more mobile stations may be intercepted based on the mobile stations being located within the geographic area, the distance between multiple mobile stations being less than a predetermined distance, or the distance between one or more mobile stations and a reference object being less than a predetermined distance. Intercepted transmissions as well as any associated data may be forwarded to one or more authorized entities, such as law enforcement agencies.

The present invention relates to a methods and arrangements for monitoring instant messaging and/or presence activity at application level in a telecommunication system, which method comprises the following steps:—A request to monitor instant messaging and/or presence activity information related to a target subscriber, which information is obtainable from any type of access and not limited to SIP clients connected to a public IMS core system is sent from an agency to a receiving entity.—A requested activity involving the target subscriber is received from an Instant Messaging and Presence Services (IMPS) system to the receiving entity.—Information related to the requested activity is delivered from the receiving entity to the agency.
摘要:
The present invention relates to methods and arrangements in a telecommunication system to monitor information related to specified services in a service unaware node. The node handles Content of Communication associated with services. The system comprises a Delivery Function to which Content of Communication related to a target is received from the node. The method comprises the following steps: Receiving from a requesting entity to the Delivery Function a request to delimit the received Content of Communication according to not desired services. Parsing the received Content of Communication according to not desired services by a Packet Inspection Feature associated with the Delivery Function. Forwarding Control Information related to the not desired services to the requesting entity.

摘要:
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 invention relates to the use of mobile networks (110) in a telematics environment. A method embodiment of the invention performed by an application server (108) accessible via the mobile network (110) comprises the steps of receiving setting information (124) via a radio interface (126) of the mobile network, wherein the setting information indicates an environment setting of an environment in which a user terminal (106) is deployed; and controlling an application (109) hosted by the application server according to the received setting information.
摘要:
Methods and apparatuses to enhance delivery capacity for traffic in a communication network are disclosed. Traffic is received to a Delivery Function with originally coded Quality of Services (QoS). A specification of requested QoS is received to the Delivery Function. The originally coded QoS is established to be higher than the requested QoS. The received traffic is transcoded into requested QoS. Optionally, the traffic is buffered with originally coded QoS and at request, the buffered traffic is retrieved.
