Abstract: Systems and methods for dynamic Radio Access Technology (RAT)/Frequency Selection Priority (RFSP) selection for a User Equipment (UE) are disclosed. In some embodiments, a method of operation of a core network entity in a core network of a cellular communications system comprises selecting a RFSP index for a UE during setup of a packet data session for the UE where the RFSP index is an index to a specific Radio Resource Management (RRM) configuration for the UE and sending a message comprising the selected RFSP index to another core network entity. In some other embodiments, a method of operation of a core network entity comprises detecting an application that is using a packet data session of a UE, selecting a RFSP index for the UE based on the detected application, and sending a message comprising the RFSP index to another core network entity.

Abstract: The present invention faces the issues of inactivating a particular control rule parameter, only for a given control rule and whilst maintaining this particular control rule parameter for other control rules and provides for methods and apparatuses whereby, upon determining by a control server that a particular parameter is no longer applicable for a first control rule, a modified control rule is determined that includes a removal indicator indicating the particular parameter to be removed for the first control rule previously installed and not for other control rules. The modified control rule is submitted to an enforcing device which removes the particular parameter only for the first control rule previously installed and not for others.

Abstract: Network nodes and methods for control thereof for dynamic network slice selection. An AMF receives a UE request originating from the UE, the UE request being any one of a registration request and a session request. A network slice requester controls a transmitter to transmit a network slice selection request to a PC_NSS. A selection data manager of the PC_NSS determines selection data specifying one or more UE specific parameters affecting network slice selection. A network slice selector selects a network slice assignable for the UE, based on the selection data, determines network slice data and a corresponding network slice routing rule, and transmits them to the AMF. A network slice manager of the AMF controls assignment of a network slice to the UE in dependence on the received network slice data and network slice routing rule.

Abstract: Methods and apparatus for controlling the transmission of user data over an NAS of a telecommunications network. An AMF includes a receiver configured to receive NAS policy control data determined by a PCF. The NAS policy control data identifies a user, is based on the user's subscription to the telecommunications network and includes one or more authorization parameters identifying whether the user is permitted to transmit user data over the NAS. The receiver also receives from a UE, or an AS, an NAS transmission request identifying the user and requesting transmission of user data over the NAS. An NAS transmission authorizer controls whether the transmission of the user data over the NAS should be authorized based on the authorization parameters and the NAS transmission request.

Abstract: An apparatus for user plane function, UPF, allocation is described. The UPF is configured to provide a Protocol Data Unit, PDU, connectivity service between a terminal device and a data network on a user plane, and the allocation is based on control information associated with an individual logical PDU entity. The control information defines priority information indicative of a priority of the PDU entity relative to other PDU entities and pre-emption information indicative of at least one of whether the PDU entity is capable of being pre-emptively allocated to a UPF over other PDU entities served by that UPF, and whether the PDU entity when served by a UPF is vulnerable to being re-allocated for pre-emptively allocating other PDU entities to that UPF. The apparatus is configured to detect an event that requires UPF allocation to a first PDU entity, to select a first UPF, wherein the first UPF is serving one or more second PDU entities, and to determine, for the selected UPF, insufficient resources for serving the first PDU entity. The apparatus is also configured to perform, responsive to determining the insufficient resources of the selected UPF, an evaluation of first priority information associated with the first PDU entity relative to second priority information associated with the one or more second PDU entities and at least one of first pre-emption information associated with the first PDU entity and second pre-emption information associated with the one or more second PDU entities. The apparatus is further configured to trigger, dependent on the result of the evaluation, allocation of the first PDU entity to either the first UPF or a second UPF.

Abstract: An IMS registration and session initiation is disclosed for a user equipment (UE). The UE has a subscription identifier comprising an IMSI and/or MSISDN. A PDN-GW establishes (s10) an IP-CAN session with a PCRF, for the UE, by transmitting, to the PCRF, the subscription identifier of the UE and an IP address assigned to the UE. The PCRF binds (s20) the subscription identifier to the IP address assigned to the UE for the IP-CAN session. Then, upon the UE initiating the IMS registration, a P-CSCF transfers (s30), to an S-CSCF, an IMPU. The S-CSCF obtains (s40), based on the IMPU, the subscription identifier of the UE from a user database. The S-CSCF transfers (s50) to the P-CSCF the obtained subscription identifier of the UE. The P-CSCF binds (s60) the subscription identifier of the UE to the IMPU. Then, upon the UE initiating an IMS session associated with the IMPU, the P-CSCF establishes (s70) an AF session towards the PCRF with the subscription identifier bound to the IMPU. The PCRF then identifies (s80) the correct IP-CAN session by matching the subscription identifier with the one of the IP-CAN session.
Abstract translation: 公开了用于用户设备（UE）的IMS注册和会话发起。 UE具有包括IMSI和/或MSISDN的订阅标识符。 PDN-GW通过向PCRF发送UE的订阅标识符和分配给UE的IP地址来建立（S10）与PCRF的IP-CAN会话。 PCRF将订阅标识符（s20）绑定到分配给用于IP-CAN会话的UE的IP地址。 然后，在UE发起IMS注册时，P-CSCF向S-CSCF，IMPU传送（s30）。 S-CSCF从用户数据库基于IMPU获取UE的订阅标识符（s40）。 S-CSCF向P-CSCF传送所获得的UE的订阅标识符（s50）。 P-CSCF将UE的订阅标识符（s60）绑定到IMPU。 然后，在UE发起与IMPU相关联的IMS会话时，P-CSCF向订阅标识符绑定到IMPU的PCRF建立（s70）AF会话。 然后，PCRF通过将订阅标识符与IP-CAN会话中的一个进行匹配来识别（s80）正确的IP-CAN会话。
