摘要： In some examples, a user equipment (UE) is registered with a fifth generation (5G) core network. In response to an emergency indication, the UE selects a first domain intended for a call responsive to the emergency indication. Subsequent to selecting the first domain, the UE attempts a combined registration with a second core network different from the 5G core network. In response to attempting the combined registration, the UE receives a further indication that the UE is registered for packet switched services but not circuit switched services. In response to the further indication, the UE selects an access network connected to a third core network to perform the call.

摘要： In some examples, a device detects a calling identifier received as part of initiating a call matches an emergency identifier, the emergency identifier associated with information from which to derive a Uniform Resource Name (URN). The device detects that the device is in a first network different from a second network, where the second network configured the emergency identifier. In response to detecting that the device is in the first network different from the second network, the device includes a URN, urn:service:sos, in a Session Initiation Protocol (SIP) INVITE message to be transmitted.

摘要： There is provided a method and device for provisioning emergency number information on a user equipment. When a dialed number matches an emergency number from the provisioned emergency number information, the user equipment selects either the circuit switched domain or the packet switched domain and executes a call setup procedure for that domain.

摘要： An embodiment provides a user equipment that includes a processor configured to receive a Session Initiation Protocol (SIP) NOTIFY message transmitted by a network component as a result of a registration event. The SIP NOTIFY message contains at least a portion of information included in a first SIP message sent between a first user equipment and the network component. Another embodiment provides method and apparatus for a network node to determine whether filter criteria include one or more indicators that specify the need for information, and including in a second SIP message the information specified by the one or more indicators.
