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: 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and provides for methods and apparatuses whereby, upon determining by a control server that a particular parameter is no longer applicable for a first control rule, a modified control rule is determined that includes a removal indicator indicating the particular parameter to be removed for the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: A method of establishing a Packet Data Unit, PDU, session between a User Equipment, UE (51; 600), and a data network identified by a Data Network Name, DNN, in a telecommunication network. The telecommunication network comprising an Access and Mobility Function, AMF (56; 66; 500), and a Policy Control Function, PCF (60; 700).

Abstract: A control apparatus initiates, in response to a predetermined condition being satisfied, a provisioning, to a communications terminal, of information of a portion of a management object. The control apparatus generates, and transmits to the communications terminal, one or more commands comprising information of the portion including information of a reference node which is a leaf node of the management object and which contains reference information specifying a sub-tree comprising specific access network related information. The communications terminal receives the one or more commands, stores the information of the portion comprised in the one or more commands in accordance with the one or more commands, and acquires the specific access network related information of the sub-tree using the reference information of the reference node included in the information of the portion.

Abstract: According to the invention in a first aspect, there is provided a communication device (114, 200) configured to form part of a telecommunications network and to carry out an access network discovery and selection function, ANDSF. The communication device comprises a receiver (204) configured to receive a request for access network policy information relating to a user equipment, UE, (100, 300) and current UE location data. The communication device comprises a policy information unit (214) configured to determine primary information comprising access network policy information for the UE based at least in part on the current UE location data. The policy information unit is further configured to determine secondary information specifying one or more further UE locations at which the UE should make a further request for access network policy information. The communication device comprises a transmitter (202) configured to transmit the primary and secondary information towards the UE.

Abstract: The present specification faces the issue of detecting collisions caused by concurrent processes which operate on shared data, without compromising bandwidth and system performance. The present specification provides for: a user data repository that, for one or more requests to read data from different application front-ends, provides the data along with a current version value assigned to the data; a first application front-end that, upon determining a data modification, submits a modification request to the user data repository including a first replace indication with the data to be modified, a delete indication with the current version value received, and a second replace indication with a new version data to assign for the data to be modified; and wherein the user data repository accepts the modification if the current version value received from the application front-end matches the current version value at the user data repository, or rejects it, otherwise.

Abstract: This invention relates to methods, user equipment, access controller, and equipment identity register for controlling access of a user equipment, UE, (100) to services provided by a communication network (101). The UE (100) is adapted to support at least a first access technology (202), said at least first access technology (202) is associated with at least one first equipment identifier (206), and said first equipment identifier uniquely identifies the UE (100). The method comprises the first steps of receiving a network access request to services via said first access technology (202), said network access request comprising said first equipment identifier (206). The method comprises the second steps of receiving at least one additional equipment identifier not related to said first access technology (202), said additional equipment identifier uniquely identifying the UE (100). The method comprises the third steps of and controlling the UE's (100) access to the services based on the received information.

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.
