Aspects of the present disclosure propose solutions to a problem of mobility interruption during handover between base stations by providing a UE with mechanisms to report the UE capability for simultaneous connectivity based handover, or so-called Dual Active Protocol Stack Handover (DAPS-HO). A UE reports the DAPS-HO capability of the UE to the network and then the base station initiates physical layer procedures to carry out DAPS-HO in accordance with the DAPS-HO capability reported by the UE. Aspects of the present disclosure also provide examples of signaling that may be used by the UE for reporting DAPS-HO capability to the network and the physical layer procedures that the UE may follow in accordance with the configuration that the network provides to the UE, which should be in accordance with the UE's capability.

The present disclosure provides a method for implementing service, a network unit and a terminal. The method for implementing service, operable by a terminal, includes: obtaining indication information for an operation from a first network to a second network; determining an operation for the related service, according to the indication information for the operation from the first network to the second network.

Systems and methods for dynamically managing the states (e.g., enabling/disabling) of telecommunication services/features are disclosed. To do so, the system associates parameters (e.g., timers) with the impacted services/features. For example, when a user experiences issues with voice calls, he/she calls the telecommunications service provider (carrier) to help resolve the issue. A customer care representative may ask the user to temporality turn off the VoNR service to help alleviate the issue. When the user turns off (or toggles off) the VoNR service on his/her mobile device, the system can start a configurable timer (parameter) for the VoNR service. In this manner, the system can replace the conventional toggle on/off feature with a time-based feature. The system monitors the timer's value and when the timers value reaches a target value (e.g., 24 hours, 1 week, etc.), the system alerts the user that the VoNR service will be turned on (or toggled on).

A cable communications network provides an alternative communications path between a user equipment device and a data network to a cellular path for a communications session with a desired level of Quality of Service. A cable modem termination system, coupled to a wireless core network, e.g., a 5G core network, interacts with the wireless core network to attempt to establish a PDU session for a UE with a desired QoS level. The core sends a QoS service request message to the CMTS including a requested level of QoS, an IP address and port number for the session. The CMTS and cable modem, corresponding to the UE, negotiate and decide if the request desired QoS level can be supported over the cable between the CMTS and the cable mode for the session.

Apparatuses, methods, and systems are disclosed for voice session handover. One method (800) includes receiving (802) a handover message including first information indicating a voice handover request to handover a voice session from a first network to a second network. The method (800) includes determining (804) a first network function configured to facilitate communication with the second network. The method (800) includes transmitting (806) a relocation request message to the first network function, wherein the relocation request message includes second information related to the voice handover request. The method (800) includes receiving (808) a relocation response message from the first network function, wherein the relocation response message indicates completion of a voice handover. The method (800) includes transmitting (810) third information related to the voice handover to a third network function, wherein the third network function suspends non-guaranteed bit rate data flows.

Embodiments of a system and method for providing DRX enhancements in LTE systems are generally described herein. In some embodiments, a system control module is provided for controlling communications via a communications interface. A processor is coupled to the system control module and is arranged to implement an inactivity timer and an on-duration timer for determining an active time for monitoring subframes on the physical downlink control channel for control signals, the processor further monitoring subframes after the active time.

A method is provided. The method may be performed by a UE. The method includes attempting to attach to or to perform a tracking area update in an EPS network to obtain voice services for a number of times. The method includes starting a modified timer based on a failure to attach to or to perform the tracking area update in an EPS network for the number of times and based on a configuration parameter. The modified timer may be modified based on a default timer. The method includes keeping an S1 mode enabled when starting the modified timer. The method includes attempting to obtain the voice services based on one or more access technologies other than EPS. The method includes attaching to or performing a tracking area update in the EPS network to obtain voice services based on the modified timer.

The present technology is generally directed to optimizing a non-3GPP untrusted Wi-Fi to 5G system handover followed by Evolved Packet System (EPS) fallback, more specifically, to delaying removal of the Wi-Fi session resources and creating a voice flow as part of the EPS fallback. The present technology can receive a request for an EPS fallback from a mobile device for a handover to a 5G network while the mobile device is in communication over non-3GPP access network, maintain one or more resources of the non-3GPP access network during data path switching from the non-3GPP access network to the 5G network, generate a list of EPS bearer identifiers to transmit to an access and mobility management function (AMF), wherein the list of EPS bearer identifiers is associated with a voice flow to transfer the one or more resources of the non-3GPP access network as part of the handover from the non-3GPP access network to the 5G network, and transmit the list of EPS bearer identifiers to a mobility management entity (MME).

A quantum resistant method is provided for supporting user equipment (UE) roaming across APs/eNBs/gNBs belonging to various Wireless LAN Controllers (WLCs) in enterprise 5G and WiFi co-located deployments. The method may include initializing a SKS server in an electrical communication with a master WLC with a random post-quantum common secret seed (PQSEED) to generate a post-quantum pre-shared key (PQPSK) and a respective PQPSK-ID. The method may also include sending an encrypted PQSEED along with a PQPSK-ID to a second WLC. The method may further include joining AP (WiFi) to the master WLC using a CAPWAP/DTLS protocol. The method may further include sending the PQPSK-ID from the master WLC to the UE in an EAP success packet when the UE is associated with the AP (WiFi).

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.
