摘要:
A method of delivering packets from a radio access network to a user terminal. The method comprises establishing a radio access bearer for transporting data to the user terminal from a radio layer control entity responsible for constructing downlink radio frames. Within the radio access network, an IP traffic flow destined for said user terminal is observed and a delivery priority determined for the IP traffic flow taking into account a user application to which the traffic relates. The delivery priority is dynamic ally adjusted in dependence upon the desired arrival time or delivery rate of packets within the IP traffic flow at the user terminal. With respect to other downlink user traffic to be sent over the radio interface, packets of the IP traffic flow are scheduled for transmission to the user terminal over the established radio access bearer, and or the scheduling weight of radio frames of the established radio access bearer adjusted, in accordance with the current delivery priority. The method further comprises, upstream of said radio layer control entity, carrying out a pre-scheduling of packets of said IP traffic flow with respect to other IP traffic flows.

A technique for identifying at least one mobile terminal travelling in a vehicle is disclosed, wherein the vehicle comprises a connected device. In a method aspect, the method comprises initializing a list of identifiers, IDs, of at least one candidate mobile terminal currently travelling in the vehicle, obtaining a current first position of the connected device and a current second position of the at least one candidate mobile terminal, comparing the current first position and the current second position so as to determine whether the current first and second positions match, and iteratively refining the list of IDs depending on the match of the current first and second positions by repeating the steps of obtaining and comparing until a predetermined condition is met.

Methods and a first node (110), a second node (120) and a network node (130) for managing traffic characteristics of one or more packets on a connection are disclosed. The first node (110) exchanges (303), with the network node (130), traffic characteristic semantics and a common key for encryption of a traffic characteristic value to be applied for the one or more packets on the connection, wherein the traffic characteristic semantics include the traffic characteristic value and an associated characteristic for the one or more packets. Moreover, the first node (110) sends (309) the traffic characteristic value and the common key to the second node (120). The network node (130) checks and applies (312) the traffic characteristics value according to service policies of the network node (130). Next, the first node (110) exchanges (311), with the second node (120), payload which includes one or more packets over the connection. Information about the traffic characteristic value is included in a transport header of each packet carrying the payload.

A technique for relocating a Serving Gateway associated to a User Equipment is described. One method implementation of this technique is performed in a Mobility Management Entity, MME, and comprises the steps of a) triggering, from the MME, a relocation of a source SGW to a target SGW by sending a Create Session Request message to the target SGW, b) receiving, from the target SGW, a Create Session Response message including S1 General Packet Radio Service, GPRS, Tunnelling Protocol, GTP, endpoints of the target SGW, c) updating, from the MME to an Evolved NodeB, eNB, an Internet Protocol, IP, address and a Tunnel Endpoint IDentifier, TEID, of the target SGW, and d) sending, from the MME to the source SGW, a Delete Session Request to delete a session.

A method is provided which introduces user plane caching over an interface between a first node in a radio access network and a second node in a core network. At the first node: receiving first uplink tunnel parameters relating to the second node, selecting first downlink tunnel parameters relating to the first node, sending the first uplink and downlink tunnel parameters to a cache node designated to the first node, receiving second uplink and downlink tunnel parameters relating to the cache node, and sending the second downlink tunnel parameters to the second node. A first tunnel is established between the first node and the cache node based on the second uplink tunnel parameters and the first downlink tunnel parameters, uplink user plane data is sent to the second node through the first and second tunnels via the cache node, and downlink user plane data is received from the second node.
摘要:
The present invention relates to a mobility management control node (111, 113) of a mobile communications network (100) and to a method in the mobility management control node (111, 113). According to the method a 5 gateway (105, 106, 117) is allocated to a bearer (110, 118). The method comprises determining an appropriate gateway for the bearer (110, 118) and obtaining load information indicating a current load of the determined appropriate gateway. If the load information indicates that the current load of the determined appropriate gateway is above a predetermined threshold 10 value of the determined appropriate gateway, a gateway out of the determined appropriate gateway and at least one other gateway is selected based on information associated with the bearer. On the other hand, if the load information indicates that the current load of the determined appropriate gateway is below or at the predetermined threshold value, the determined 15 appropriate gateway is selected. The selected gateway is allocated to the bearer (110, 118).
