Abstract: A server-implemented method is disclosed. The method includes: receiving a request from an IP Multimedia Subsystem (IMS) network node of an IMS network; and in response to receiving the request, providing NAS registration state information associated with a user equipment (UE) to the IMS network node, the NAS registration state information indicating at least one of fourth-generation (4G) single radio voice call continuity (SRVCC) capability of the UE or fifth-generation (5G) SRVCC capability of the UE that is applicable when using an access network supported by a core network, wherein the server is configured to store separate instances of UE SRVCC capabilities, the separate instances including indications of at least one of 4G UE SRVCC capability or 5G UE SRVCC capability that is applicable when using the access network supported by the core network, and wherein the UE is registered with the IMS network using a session initiation protocol (SIP) via the access network.

Abstract: Described herein is a system and method in a user equipment (UE) supporting registration using third generation partnership project (3GPP) access and using non-3GPP access, the method comprising storing, in a memory of the UE, first emergency information received using first registration procedures; receiving, by the UE, a REGISTRATION ACCEPT message using second registration procedures via non-3GPP access; and keeping, in the memory, the first emergency information after receiving the REGISTRATION ACCEPT message.

Abstract: Methods and devices for encoding a point cloud. A current node associated with a sub-volume is split into further sub-volumes, each further sub-volume corresponding to a child node of the current node, and, at the encoder, an occupancy pattern is determined for the current node based on occupancy status of the child nodes. A probability distribution is selected from among a plurality of probability distributions based on occupancy data for a plurality of nodes neighbouring the current node. The encoder entropy encodes the occupancy pattern based on the selected probability distribution to produce encoded data for the bitstream and updates the selected probability distribution. The decoder makes the same selection based on occupancy data for neighbouring nodes and entropy decodes the bitstream to reconstruct the occupancy pattern.

Abstract: A system and method in a user equipment (UE) for transferring an emergency session from a first network to a second network. The method includes transmitting a first registration request message to the second network; receiving a registration reject message from the second network; detecting the emergency session between the UE and the first network is ongoing; transmitting a second registration request message comprising an emergency registration request to the second network; and receiving a registration accept message for the emergency session.

Abstract: 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.

Abstract: A method at a user equipment for obtaining emergency codes using a non-Third Generation Partnership Project (3GPP) network, the method including sending a request message to a network node, the request message containing an indication; and receiving, at the user equipment, a response message, the response message including at least one mobile country code (MCC), and the response message indicating an emergency number, type or category information, wherein the emergency number, type or category information is associated with the at least one MCC, and wherein the at least one MCC indicates a portion of a Public Land Mobile Network (PLMN) code to which the emergency number, type or category information applies.

Abstract: A method for steering of roaming (SOR) in wireless communication networks includes sending by a mobile equipment (ME) a registration message to a visited public land mobile network (VPLMN). The ME receives a first message from a home public land mobile network (HPLMN) through the VPLMN. The ME determines that the first message has failed a security check. In response to determining that the first message has failed the security check, the ME sends a second message to the VPLMN, the second message including an indication that the first message has failed the security check.

Abstract: A method implemented by a network node is disclosed. The method includes: obtaining registration state information associated with a user equipment (UE) from a first core network node, the registration state information indicating at least one of fourth-generation (4G) UE single radio voice call continuity (SRVCC) capability or fifth-generation (5G) UE SRVCC capability for the UE, wherein the UE is registered with a first IMS network that includes the network node using a session initiation protocol (SIP) via an access network supported by a second core network; and providing, to a second IMS network node, an indication of a single UE SRVCC capability for the UE.

Abstract: In some examples, a wireless device receives, from a wireless access network node, an indication of a supported extended emergency information (EEI) type supported by a wireless local area network (WLAN). The supported EEI type is selected from among a plurality of different EEI types. The wireless device sends a message relating to an emergency call, the message including EEI data according to the supported EEI type.
