Method for providing virtual private network services between autonomous systems

Abstract: The present invention relates to providing virtual private network (VPN) services between two or more Autonomic Systems (AS). An aggregation edge router (ASBR) is provided in two or more autonomous systems (Asx,Asy). The aggregation edge routers are configured such that routing peering between the two or more autonomous systems is done between the aggregation edge routers in these autonomous systems. Each aggregation edge router is a routing peer of other edge routers (PE) in its own autonomous system. The Multi-Protocol Label Switching (MPLS) network is used between the different autonomous systems.

A method and system for protecting a user identifier

Abstract: The present invention relates to a method and a system for protecting the user identifier of a service user from the service provider in a mobile communication network, which service to be provided/used is a content service utilizing the geographical information of the service user. The system comprises a terminal device of the service user (11) for sending the service request to the service provider; equipment of the service provider (12) for generating the service response and sending it to the service user; and a mobile communication network (10) for transmitting the service request and the service response. In accordance with the invention, the system comprises an encrypting device (13) for generating the service-request-specific anonymous identifier corresponding to the user identifier; an identification database (13) for storing the user identifier and corresponding anonymous identifier; a service gateway (14) for retrieving the user identifier and the anonymous identifier corresponding to one another and for substituting the identifiers in question with one another in the service requests and service responses directed to the service gateway in question; and a location register (15) for retrieving the user identifier corresponding to the anonymous identifier as well as for retrieving the geographical information of the service user based on the user identifier in question.

Billing in mobile communications system employing wireless application protocol

Abstract: The invention relates to a network part of a mobile communications system employing a wireless application protocol and a method for generating billing data in a mobile communications system employing a wireless application protocol. The network part of the mobile communications system comprises: means (104, 106, 118) for setting up a bi-directional wireless data transmission connection (102) to a subscriber terminal (100) of the mobile communications system; means (126) for transmitting a service request (150, 152) sent by the subscriber terminal (100) to a contents server (136) providing the service; means (126) for transmitting response data (154, 156, 158, 160) generated in the contents server (136) on the basis of the service request (150, 152) to the subscriber terminal (100). The network part further comprises: identifying means (130, 132) for identifying transactions associated with the service from among the service requests (150, 152) and the response data (154, 156, 158, 160) on the basis of the identification of the Internet address of the service referred to in the service request (150, 152) and the response data (154, 156, 158, 160); and billing means (134) for generating billing data for the service using the transactions identified on the basis of the service"s Internet address.

Evaluations of LTE Automatic Neighbor Relations

Abstract: In recent years, there has been a strong focus on network management simplicity under the device self-organizing networks (SON). A number of SON use cases and features have been and are discussed for 3G Long Term Evolution (LTE). The main SON feature in the first LTE release is methods for automatic configuration of neighbor cell relations - Automatic Neighbor Relations (ANR). In this paper, we describe the neighbor relations management and ANR, and evaluate ANR in a pre-launch, commercially deployed network cluster. The results indicate that ANR configures discovered and needed neighbor relations such that handover can be performed in combination with the neighbor relation establishment without dropping the connection.

Method, system and router providing active queue management in packet transmission systems

Abstract: The present invention provides a method of active queue management for handling prioritised traffic in a packet transmission system. The method is able to provide differentiation between traffic originating from rate adaptive applications that respond to packet loss. Traffic is assigned one, of at least a first and second, drop precedent level, namely in profile and out of profile. The method includes the steps of: calculating an average queue length, avg-ql; assigning minimum thresholds, min-th-in and min-th-out, for in profile packets and out of profile packets respectively, and a maximum threshold, max-th; retaining all packets with their initially assigned drop precedent levels while the average queue length is less than, or equal to, a threshold th-in; assigning a drop probability to each packet, determined from the average queue length; retaining all packets while avg-ql is less than th-in; and dropping packets in accordance with their assigned drop probability; the parameter max-p-out is greater than max-p-in, where max-p-out is the maximum drop probablity of packets marked as out of profile and max-p-in is the maximum drop probability for packets marked as in profile.
