  • Publication number: 20120214501
    Abstract: A method in a user equipment for handling cell selection is provided. While in dedicated mode the user equipment receives from a radio network node a measurement information message which indicates at least two frequencies associated with a respective cell in a respective radio access technology. While it is in dedicated mode, the user equipment performs measurements on the frequencies to obtain a respective measurement value for each one of them, and receives a selection indicator message comprising a respective priority for each one of the frequencies. The user equipment obtains a respective threshold value for each of the frequencies and successively evaluates the frequencies in descending priority order until a frequency is determined for which the measurement value exceeds its respective threshold value. When entering idle mode, the user equipment selects cell based on the evaluation.

  • Patent number: 8180344
    Abstract: A 2G controlling entity in a common 2G/3G network that includes a common Core Network is connected to dual mode mobile stations and to a 3G controlling entity also connected to dual mode mobile stations. The 2G controlling entity applies a 3G camping strategy and receives a service request, for a service at least supported by the 2G network, from a dual mode mobile station. The 2G controlling entity instructs the dual mode mobile station, when connected to the 2G network, to perform cell reselection evaluation of 3G network cells only when the 2G network signal strength is below a predetermined threshold.

  • Publication number: 20120076052
    Abstract: Embodiments of the present invention a method and a node for finding the shortest path to a cache node in a content delivery network (CDN) comprising requested content and a method for creating a virtual representation of a network. According to an embodiment of the present invention, the virtual representation is in the form of a virtual, hierarchical topology, and the cache nodes correspond to the cache nodes of the real network. All cache nodes are arranged at a first level and with the virtual nodes arranged at higher levels. In the virtual representation, all nodes (cache and virtual) are connected with virtual links such that there exist only one path between any two arbitrary cache nodes. Further, costs to the virtual links are assigned such that the path cost between any two arbitrary cache nodes in the virtual representation generally corresponds to the lowest path cost between corresponding cache nodes in the real network.

  • Publication number: 20120072526
    Abstract: The present invention relates to a method and node for efficiently distributing electronic content in a content distribution network (CDN) comprising a plurality of cache nodes. Embodiments of the present invention include a virtual node logically representing a set of cache nodes. The set of cache nodes is in turn defined based on an internal communication cost between the cache nodes. In each of the cache nodes represented by the virtual node statistics regarding content requests is collected, and based on this statistics it is determined whether specific content is to be cached in the virtual node or not. If it is determined to cache specific content in the virtual node, the specific content may be caused to be cached in one or more of the cache nodes represented by the virtual node.

  • Publication number: 20110256873
    Abstract: A system, method, and User Equipment, UE, for providing a current LTE cell location to a Generic Radio Access Network Controller, GANG, based on different triggers depending on the UE state. The GANC ensures that the correct GANG is serving the UE, and also maps the LTE cell location to an associated GAN Cell Global Identifier, GAN-CGI. The GANG provides the GAN-CGI to a Mobile Switching Center, MSC, or other serving core network node to support location-based services and other mobile originated or mobile terminated calls and transactions.

  • Publication number: 20110207462
    Abstract: A method and system wherein a Voice over LTE via Generic Access (VoLGA) Access Network Controller (VANC)1 upon receiving a REGISTER and REGISTER UPDATE message from the UE1 notifies a Hand Over Selection Function node (HOSF) that a user equipment (UE) is registered in the VANC. This will only be done if the HOSF has not theretofore been notified.

  • Patent number: 7996537
    Abstract: Illegitimate use of IP addresses is counteracted. A network (1) includes a switch (5) with ports (P1,P2,P3) to subscribers (6,6A) and a port (PN) to a core network (2) with DHCP servers (4, 4a,4b). The switch includes a database (MAC1, MAC2), port numbers (P1, P2)) and VLAN identities (VLAN1, VLAN2) for the subscribers (6, 6A) and the filter has a list over trusted DHCP servers. Initially onlY DHCP messages from the subscribers are allowed. When the subscriber (6) requests (M1, M3) for an IP address it is checked that it is a DHCP message with valid subscriber values (MAC1, P1, VLAN1). A respond (M2, M4) with an allocated IP address (IP1) and lease time interval (T1) is checked to come from a trusted DHCP server. If so, a list in the filter (9) with correct information is dynamically generated (MAC1, P1, VLAN1, IP1, T1). A message (M5) from the subscriber (6) with false IP address is discarded by the filter. Attempts by the subscriber to use false IP address are counted and a warning signal is generated.
