A core network device of a telecommunications network can receive a first request from a consumer network function (NF) and forward the first request to a first provider NF. The device can subsequently detect a violation by the first provider NF of a response criterion. The device can receive a second request and forward the second request to a second, different provider NF in response to the violation. In some examples, the device can later detect that the first provider NF has satisfied the response criterion with respect to a third request. The device can modify load data to increase the proportion of subsequent requests for which the first provider NF is selected. The device can select provider NFs based on the load data. In some examples, a system can include a network registry device that selects NFs based on violation indications received from the core network device.

A surgical device is provided. The surgical device includes a tubular outer shaft having a longitudinal axis and an angled guide positioned on a first end of the surgical device. The angled guide may be angled relative to the longitudinal axis of the outer shaft. The surgical device includes an elongated inner shaft having a second end and a third end. The inner shaft is removably coupled to the outer shaft and configured to axially translate through the outer shaft. The surgical device includes pivotal device having at least one joint and an access tool. The at least one joint may be pivotally coupled to the third end of the inner shaft and to an end of the access tool. The pivotal device may be configured to axially translate through the angled guide into a deployed position.

Embodiments of this application provide a policy control function network element selection method, an apparatus, a system, and a storage medium The method includes: A first access and mobility management function network element receives a registration request message of the terminal device; obtains, based on an identifier of the terminal device in the registration request message, an identifier of a policy control function network element currently serving the terminal device and a network identifier of the policy control function network element; and when a network identifier of the first access and mobility management function network element is consistent with the network identifier of the policy control function network element, determines that the policy control function network element is a target policy control function network element.

The invention provides for a method of selecting a Dedicated Core Network (DCN) based on assisting indication by mobile terminals, and including the step of configuring the RAN Nodes of the mobile network with the DCN Types of the serving EPC Nodes so that the RAN Nodes can map the DCN selection assisting information from the connecting mobile terminals with the right dedicated EPC Node. This allows for the RAN Node to connect the mobile terminals with EPC Node of the mobile terminal's dedication at initial attach and then keep the mobile terminals on the same DCN. Thus, a re-routing of mobile terminals NAS message from one EPC Node to another EPC node is avoided. The invention also allows for a flexible and dynamic change of the EPC Nodes dedication based on operator's configuration and policy. Additionally, the invention allows for DCN access restriction control by broadcasting of the supported DCN Types by the RAN Node.

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.

A system is described in which a default mobility management entity (MME) receives, from a base station, a request for setting up a communication connection to a mobile device having an associated usage type. The default MME sends, to the base station and responsive to the request, a message identifying a dedicated MME, to which the request should be re-routed, the dedicated MME having a supported service type corresponding to the usage type associated with the mobile device. The base station sends a response to the default MME, the response indicating whether re-routing to said dedicated MME is was successful or not (e.g. due to an overload of the dedicated MME). If the re-routing was not successful, the default MME attempts to serve the mobile device instead of the dedicated MME.

A communication scheme and system converges a 5G communication system supporting a data rate higher than that of a 4G system with an internet of things (IoT) technology. Applicable to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars, connected cars, health care, digital education, retails, and security and safety-related services), the communication scheme and system is based on the 5G communication technology and the IoT-related technology. Methods of operation a terminal and a network for facilitating a 5G terminal registration procedure in a wireless communication system are disclosed.

The present disclosure relates to communication methods, core network devices, and access network devices. One example method includes receiving, by a core network device, a first message from an access network device, where the first message carries information used to indicate a slice supported by the access network device, and determining, by the core network device, a location area identity list of user equipment UE based on the information used to indicate the slice supported by the access network device.

Relay service is enabled between a residential gateway and a remote user. For example, a 5G residential gateway (5G-RG) may include a relay user equipment (UE) to enable relay service for a 5G core (5GC)-capable UE behind the 5G-RG to connect to the 5GC. The relay UE of the 5G-RG may provide a trusted/untrusted non-3GPP access network for L2 or L3 transport connection to the 5GC-capable UE.

A method includes obtaining, by a data analytics device, data of a terminal on an access device and data of the terminal on an access and mobility management function device, where the data of the terminal on the access device includes a first identifier, and the access device is an access device, the data of the terminal on the access and mobility management function device includes the first identifier, and the first identifier includes an identifier assigned by the access device to the terminal, associating, by the data analytics device, the data of the terminal on the access device with the data of the terminal on the access and mobility management function device based on the first identifier.
