  • Publication number: 20150139185
    Abstract: The present invention relates to a method for localization of peer-to-peer packet data traffic in a mobile network comprising a core network and at least one radio access network (RAN). The method comprises obtaining data traffic information for a packet data connection between two peers located in the RAN and where the connection is passing through a packet gateway node P-GW in the core network. If it is determined that the packet data connection is carrying peer-to-peer traffic, the PG-W requests localization policy information from a policy control function entity PCRF. The PCRF returns localization policy information related to the two peers and if localization is permitted, the P-GW requests a mobile management function entity to move the data traffic from the existing packet data connection to another packet data connection passing through another (local) packet gateway node L-GW which could be located in the same RAN as the peers.

  • Publication number: 20150049612
    Abstract: A method for determining a traffic bearer for data traffic between a terminal (106) of a mobile network (102) and a content data source (116) of a content data network (104) is described. The method comprises sending (126) a service request for data of the content data source (116) from the terminal (106) to a network gateway (110) of the mobile network (102), and determining (132) an edge entity (108) of the mobile network (102). The edge entity (112) is adapted to forward the data traffic between the content data source (116) and the mobile network (102). The method comprises sending (130) a bearer establishment request to a control node (108) of the mobile network (102) for establishing the traffic bearer (389, 589) to the edge entity (112), and directing (154) the data traffic associated with the content data source (116) to the traffic bearer.

  • Publication number: 20140355542
    Abstract: The invention refers to providing a service associated to a service request received from a mobile user equipment—UE— (10), the communications network comprising a plurality of service nodes (21a-21h), the communications network (1) receives (S2) a service request from a requesting UE (10), obtains mobility information associated to the UE (10), selects a service node (21) from the plurality of service nodes (21, 21?) in dependency of the mobility information, and transmits (S3) a response to the UE indicative of the selected service node (21) to be contacted for providing the service. The invention further refers to a gateway node and a method performed by the gateway node, a policy server and a method performed in the policy server and to corresponding programs.

  • Publication number: 20130210384
    Abstract: A gateway apparatus (40) for a user equipment (20) which is connected to a radio-access network via a relay node (10) determines that a dedicated bearer is to be created for a specific type of traffic which is to be transmitted on a data radio bearer to be created between the relay node (10) and a donor node (30) of the radio access network, and includes a parameter into a message requesting creation of the dedicated bearer, which indicates that the dedicated bearer is required for integrity protection or used to carry the specific type of traffic. The message is sent from the gateway apparatus (40) to a mobility management apparatus (50) which includes a second parameter in a message requesting setup of a radio access bearer for the type of traffic based on the parameter.

  • Publication number: 20120250565
    Abstract: An interference control method and apparatus in a self-organizing system are provided. The method includes the following steps: interference information is received at an access node from at least two other access nodes, wherein the other access nodes serve communication devices interfered by the access node; then the interference information is evaluated at the access node to determine at least one action that could be taken because of the interference; information about the determined at least one action is communicated to at least one of the at least two other access nodes, and the recipient node is operated accordingly.

  • Patent number: 8209422
    Abstract: According to one general aspect, a method may include transmitting, from a first network entity to a peer network entity, an offer to perform at least one networking function, wherein the offer includes a set of parameters indicating at least one networking capability that may be employed by the first network entity to perform the networking function. The method may include receiving, from the peer network entity, a set of parameters indicating at least one networking capability that may be employed by the peer network entity to perform the networking function. The method may include determining if at least one networking capability may be employed by both the first network entity and peer network entity to perform the networking function. The method may include selecting at least one networking capability to employ to perform the networking function. The method may include other actions as described herein.
