Abstract:
A User Plane Function, UPF (35), sends a load report to a Session Management Function, SMF (45). Responsive to receiving the load report from the UPF (35), the SMF (45) installs a load reduction policy rule in the UPF (35). The load reduction policy rule comprises a criterion for identifying one or more users subject to the load reduction policy rule. The UPF (35) selectively applies the load reduction policy rule to user plane traffic of the one or more users based on the criterion.
Abstract:
Methods of operating a network function NF node of a communication network are discussed. In such methods a message is received from an access and mobility management function AMF node. Moreover, the message includes information regarding a radio access network RAN node with respect to a communication device. Related methods of operating RAN nodes and AMF nodes are also discussed.
Abstract:
One aspect provides a method performed by a radio access network node in a telecommunications network. The method comprises: responsive to detection of a trigger event associated with a wireless device having a connection to the telecommunications network via the radio access network node or seeking to establish a connection to the telecommunications network via the radio access network node, transmitting, directly to a user plane core network node, a message initiating establishment of a user-plane tunnel for the connection between the radio access network node and the user plane core network node. The message comprises one or more of: an indication of an identifier of the wireless device; and an indication of an identifier of a session for the wireless device, and further comprises an indication of a downlink tunnel endpoint identifier of the radio access network node.
Abstract:
A method may be provided to operate a core network entity of a wireless communication network. A session establishment request may be received from a wireless terminal through a base station node. Responsive to receiving the session establishment request, the core network entity may determine that a breakout protocol data unit session is to be established for the wireless terminal. Responsive to determining that the breakout PDU session is to be established for the wireless terminal, a request may be transmitted to the base station node, and the request may include an indication that the breakout PDU session is to be established for the wireless terminal. Related methods may be provided for base station nodes, wireless terminals, and central controllers.
Abstract:
A network slice selection involves authenticating, by an identity manager (1) of a network operator (4), a user device (8) and/or user based on a network attachment request originating from the user device (8) to correlate the user device (8) and/or user to a network slice of multiple network slices (3) provided by the network operator (4).The identity manager (1) authorizes access to a network slice (3) of the network slice type based on credentials of the user device (8) and/or user. The identity manager (1) provides information of an entry point to an application provided by the network slice (3) for transmission to the user device (8).
Abstract:
A method for initiating handover of a circuit switched service using a circuit switched bearer of a mobile station (31) from a circuit switched to a packet switched domain in a mobile communications network, the mobile communications network comprising a radio network and a core network, the radio network comprising a controlling node (32, 32'), the mobile station being allocated an IP address and access port, said method comprising the controlling node communicating to the core network a relocation/handover required message; said relocation/handover required message comprising an indication of the IP address and access port allocated to the mobile station.
Abstract:
The invention is directed towards determining whether a hard handover should be performed of a mobile station (48) in relation to a first group of cells (16, 18, 20, 24) including a number of active cells (16, 18, 20) and handled by a first cell handling device (10) to a second group of cells (32, 36, 38) handled by a second cell handling device (26), when the cell handling devices lack a direct communication link (Iur). Either the first cell handling device or the mobile station obtains measurements of link quality between the mobile station and cells of the groups, determines a first and second total quality factor for the groups, performs an evaluation of a preferred group involving comparing the first total quality factor with the second quality factor and initiates a handover from the first group to the second group if the second group is preferred.
Abstract:
A serving RNC signals the load contribution of all mobiles for which it is the serving RNC to all cells controlled by another RNC that are affected by the uplink transmissions of those mobiles. This allows the other RNC to determine the contribution of those mobiles to the total uplink interference in its cells. In one example, the uplink load may be estimated using mobile-based path gain measurements.
Abstract:
A method, performed by a first node (111). The first node (111) operates in a communications network (10). The first node (111) determines (202) a predictive model of a future need to page a device (133) operating in the communications network (10). The first node (111) then outputs (204) a first indication. The first indication is based on the determined predictive model. A second node (112) operating in the communications network (10) obtains (301) the first indication, and predicts (302), based on the obtained first indication, the future need to page the device (133). A third node (113) obtains (402) a third indication from the second node (112). The third indication indicates the predicted future need to page the device (133) operating in the communications network (10). The third node (113) then determines (403), based on the obtained third indication, whether or not to page the device (133).
Abstract:
Discovery of a RAN function providing a RAN service is provided. An instance registration message is received for an instance of the RAN function. The instance registration message includes information for the instance of the RAN function. The information includes a service name identifying the RAN service and an instance identifier for the instance of the RAN function. Responsive to receiving the instance registration message, the information for the instance of the RAN function is saved. The information includes the service name and the instance identifier. A service discovery request message is received with query parameters from a service consumer node. The query parameters include the service name. Responsive to the query parameters including the service name, a service discovery response message is transmitted to the service consumer node. The service discovery response message includes the instance identifier for the instance of the RAN function.
