Patent number: 9369394Abstract: For handling user plane traffic in a communication network, a NAT node (100) determines a mapping between a network address (200-e) of a server (200) and a replacement network (200-i) address matching a packet classification rule implemented in the communication network. If the NAT node (100) receives an UL data packet (403) in which a source address identifier corresponds to a network address of a user equipment (10) and a destination address identifier corresponds to the replacement network address (200-i), it performs NAT of the UL data packet (403) in accordance with the mapping. This is accomplished at least by modifying the destination address identifier in the UL data packet (403) to correspond to the network address (200-e) of the server (200). The NAT node (100) then sends the modified UL data packet (405) toward the server (200).Type: GrantFiled: April 3, 2014Date of Patent: June 14, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Reiner Ludwig, Pablo Molinero Fernandez

Patent number: 9313797Abstract: For enabling differentiated handling of mobile network data traffic between a UE (410) and a network resource, a network address lookup procedure is adapted on the basis of mobile access information related to a connection between the UE (410) and a mobile network. The mobile access information may be obtained from authentication traffic (502, 503, 504, 505) in the mobile network and be provided to a node (560) performing the adaptation by modifying a message (508) of the lookup procedure. On the basis of the mobile access information, the adaptation may cause the lookup procedure to return a network address of a replacement network resource capable of handling the data traffic. The network address of the replacement network resource (60) matches a packet filter for directing the data traffic to a bearer established between the UE (410) and the mobile network.Type: GrantFiled: October 24, 2011Date of Patent: April 12, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Åsa Larsen, Reiner Ludwig, Pablo Molinero Fernandez

Patent number: 9077821Abstract: Currently existing mechanisms to optimize the quality of experience (QoE) in accordance with user data plans are rather based on user self-managed usage of his mobile user data plan with, for example, help from external applications which continuously evaluate the limits reached. There is thus a need for deployment of intelligence in the network, in order to avoid abrupt downgrades in the QoE for subscribers that go over the monthly quota of their data plan. To overcome these problems, or at least to mitigate them, an embodiment of the present invention provides for an optimization of the user's quota by gradually reducing the required bandwidth for the content that the user requests. This is achieved by a method which takes into account the consumed/remaining volumes in the user data plan as well as the user browsing habits, and which provides context enrichment to content providers to enable taking decisions.Type: GrantFiled: December 27, 2012Date of Patent: July 7, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Miguel Angel Pallares Lopez, Stuart Clark, Pablo Molinero Fernandez, Miguel Angel Muñoz De La Torre Alonso
