There is provided mechanisms for providing wireless network access to an external wide area network. A method is performed by a user terminal device. The method includes establishing a wireless connection to a gateway device located in a vehicle. The user terminal device is identified as a client to the gateway device. The user terminal device uses the gateway device as gateway for all data traffic exchanged between the user terminal device and the external wide area network. The method includes establishing wireless network access for the gateway device to the external wide area network. The gateway device is operatively connected to the external wide area network via the user terminal device. The user terminal device bridges all data traffic communicated between the gateway device and the external wide area network.

Wireless network access for user terminal device and gateway device in vehicle

A mobile management control entity, MBC, being adapted for communicating with an access node, AN, such as an eNodeB, the MB being adapted for issuing a message comprising an indication () of a type of traffic to be reduced to or from the AN, wherein the traffic reduction comprises one of rejecting, ignoring or selectively restricting traffic. An Access Node, AN the AN being adapted for receiving () from the MBC an indication () of a type of traffic to be reduced, receiving () a message () of a UE associated with the indication of a type of traffic to be reduced, rejecting, ignoring or selectively restricting () traffic to or from the UE belonging to the indication of type of traffic to be reduced.

There is provided a method for a mobility management node (MME) and a mobility management node for collecting mobility data of user entities, UEs, in a mobile communication network comprising a plurality of cells, wherein at least one cell or a group of cells are forming a tracking area, TA, in which paging of a given UE may be undertaken. At least the mobility management node is adapted for holding a TA list for a given UE defining a larger paging area in which paging may be performed throughout the area and in which TA update need not be undertaken by the UE in question before moving out of said area; the UE being required to perform a TA update procedure if moving out of the larger paging area. The method comprises: continuously registering mobility events pertaining to a plurality of UE's in the network, wherein for each of the plurality of UE's: assigning a link strength indicative of the frequency at which UE's are travelling a link in question; and building a table of links and associated link strengths in the network. The method further comprises for a given UE when performing a TA update procedure and upon moving from a second source TA to a second target TA: investigating based on at least the location of at least one of the source TA and the target TA; one or more probable travel paths potentially comprising a series of interconnected links and originating in either the source TA or the target TA; the probable travel paths being selected by taking into account the strength of the associated links in the table; the probable travel paths moreover being selected by taking into account the limit of a TA list length applying for the UE in question; and generating a TA list comprising the TA's constituted by the probable travel paths.
