摘要:
A method in a Radio Access Network Congestion Awareness Function, RCAF (200), of sending, to a Policy and Charging Rules Function, PCRF (100, 100-1 - 100-3), of a mobile communications network (1), congestion information (415) for a plurality of mobile entities, UEs (400-1 - 400-8), each one of the plurality of UEs (400-1 - 400-8) being connected to a respective radio access network (10) of the mobile communications network (1) and associated with the PCRF (100, 100-1 - 100-3), the congestion information (415) indicating congestion of the respective radio access network (10). The method comprising sending a Radio Access Network User Plane Congestion Information, RUCI, report (501) for transmitting congestion information of a given UE (400-1-400-8) to a PCRF (100, 100-1 - 100-3), including congestion information (415) and an identity (414) of the given UE (400-1 - 400-8) of the plurality of UEs (400-1 - 400-8), wherein the RUCI report (501) is routed by a Diameter Routing Agent, DRA (600) to the PCRF (100, 100-1 - 100-3), and receiving a response message (502) including an identity (413) of the PCRF (100, 100-1 - 100-3) associated with the given UE (400-1 - 400-8). The method further comprising aggregating the congestion information (415) for at least some of the plurality of UEs (400-1-400-8) based on the respective UEs (400-1 - 400-8) being associated with the PCRF (100, 100-1 - 100-3), and sending a message (411-1, 411-3) including the aggregated congestion information (415) to the PCRF (100, 100-1 - 100-3), wherein said sending of the message (411-1, 411-3) employs the retrieved identity (413) of the PCRF (100, 100-1 - 100-3) to route the message (411-1, 411-3) to the PCRF (100, 100-1 - 100-3).

摘要:
The present invention relates to a method, mobile station and base station in a soft handover cellular communications system. A problem addressed is the complexity imposed by a soft handover combination node in the network for combining packets received from one mobile station over parallel diversity links. The combination node is a problem with respect to the network complexity, transmission capacity and retransmission delays. The present invention solves the problem by selecting on a packet-by-packet basis one of an active set base stations for forwarding the packet further uplink. Thereby no combination node in the network is needed. The mobile stations select the base station after transmitting a packet or prior to transmitting it. The selection is based on measures of the radio link qualities made during transmission of the relevant packet or made prior to its transmission.

A User Equipment comprises a master clock, for example a Precision Time Protocol, PTP, or Precision Time Control Protocol, PTCP, network clock. The User Equipment further comprises circuitry configured to set the master clock based on signals from a wireless communications network node and a time offset, wherein the time offset is based on the propagation delay between the wireless network node and the User Equipment. The circuitry is further configured to send timing information to a network device in a communications network having a slave clock, whereby the network device can synchronize its slave clock with respect to the master clock comprised within the User Equipment.

The present invention provides a system, apparatus and method wherein the network initiates a PDP context activation for a second PDP context using a new IP address that can be used for new transport sessions whenever one or more operator configured criteria apply. For example, the present invention can be used to: (1) route ongoing and new communication sessions from the old network device associated with the old IP address through a new network device associated with the new IP address using the old IP address; (2) route ongoing communication sessions from the old network device through the new network device using the old IP address, and new communication sessions directly through the new network device; or (3) route ongoing communication sessions from the old network device through the new network device without using the new IP address, and new communication sessions directly through the new network device.
