Distributed network edge security architecture

A method performed by a first IP multimedia system, IMS, node (), for handling a network function in a communication network. The first IMS node () requests a first core network node () for at least a part of contact information of a network function instance, and receives a response from the first core network node () with at least the part of the contact information for the network function instance. The first IMS node () communicates with a second IMS node () or a core network node over a service based interface, based on the received part of the contact information for the network function instance.

First IMS node, first core network node, second IMS node, and methods performed therein

Embodiments herein relate to e.g. a method performed by a user equipment, UE, for handling a service in a wireless communication network. The UE perform, upon handling an emergency service, a connection to a second cell of a second RAT for handling the emergency service, and performs the emergency service in the second cell of the second RAT. The UE then stays connected in the second cell of the second RAT for a time interval relating to initiation of the emergency service or finalization of the emergency service.

Network node, user equipment, and methods performed in a communication network

A process of operating a first network node in a first communication network can include establishing a control plane interface between the first network node and a second network node in a second communication network. The process can further include communicating first control plane data via the control plane interface. The first control plane data can be associated with operation of a user equipment, UE, in a first communication system of the first communication network. The process can further include determining that the UE has moved to a second communication system of the first communication network. The process can further include maintaining the control plane interface between the first network node and the second network node in the second communication network. The process can further include communicating second control plane data via the control plane interface.

Maintaining N32 interface when using different radio access technologies

There is provided mechanisms for establishing a communication session with a local serving network. A method is performed by a terminal device. The method comprises obtaining an indication of traffic to be communicated. The traffic is associated with a traffic descriptor. The method comprises selecting a URSP rule for the traffic to be communicated in a communication session with the local serving network. The URSP rule is selected in accordance with the traffic descriptor and in accordance with a validity condition for the communication session. The validity condition at least pertains to network support for IMS in the local serving network. The method comprises establishing a communication session with the local serving network for communicating the traffic according to the selected URSP rule.

Session establishment with a local serving network

Methods and apparatuses are disclosed for implementing mobile terminating call. According to an embodiment, a subscriber management node obtains, from a mobility management node, an indication that indicates whether a packet switching (PS) connection is currently active for a terminal device. The subscriber management node receives, from a server, a first query about whether a PS access domain is to be used for a terminating call to the terminal device. The subscriber management node sends a response to the server based on the obtained indication.

Methods and apparatuses for implementing mobile terminating call

Apparatuses and methods for short message service (SMS) delivery are disclosed. In one embodiment, a method implemented in a unified data management, UDM, node includes setting a short message service, SMS, function, SMSF, registration notification flag to detect an SMSF registration event associated with a user equipment, UE. In another embodiment, a method implemented in a home subscriber server, HSS, node includes sending a request to subscribe to a notification at a unified data management, UDM, node about a short message service, SMS, function, SMSF, registration event associated with a user equipment, UE.

Short message service (SMS) delivery

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.

Dynamic RSFP

A node of a wireless communication network () receives an indication from a user equipment (). The indication indicates that a limitation of volume charged packet data services is required for the user equipment (). Depending on the received indication, the node () prevents transmission of packet data associated with the volume charged packet data services and allows transmission of packet data associated with one or more other packet data services.

Packet data connectivity control with volume charged service limitation

According to techniques disclosed herein, a Visited Communication Network (VCN) () selectively reports usage information back to a Home Communication Network (HCN) () for user traffic that is offloaded at the VCN () to a Data Network (DN) () rather than routed back to the HCN (). Among the various advantages, the reporting supports charging operations in the HCN () regarding the offloaded traffic. Further advantages include the application of policy control and service-authorization control jointly between the VCN () and the HCN ().

Method and network node for home charging of offloaded traffic at visited network

A method performed by a first base station associated with a preferred access network includes initiating a first handover of a wireless device to a second base station associated with a non-preferred access network in response to fulfillment of a condition. Information indicating that the wireless device is subject to a forced access change is transmitted to a second base station associated with the non-preferred access network. The information also indicates that a second handover of the wireless device should be initiated to hand the wireless device back to the first base station or another base station associated with the preferred access network as soon as the condition is no longer fulfilled.

Optimized handling of traffic management-initiated access change

Systems and methods are disclosed herein for performing a controlled handover of a wireless device from an incoming access network to a cellular access network of a visited cellular network. In some embodiments, a method for handover of a wireless device from an incoming access network to a cellular access network of a visited cellular network while in roaming comprises, at the wireless device, sending a message to a core network of the visited cellular network. The message is related to a handover of the wireless device from the incoming access network to the cellular access network of the visited cellular network and comprises an incoming access indication. The incoming access indication is an indication of the incoming access network. The method further comprises, at the core network node, receiving the message and making a decision for the handover based on the incoming access indication.
