Abstract

A method is provided for managing mobile end-of-service (MT) information for a multi-subscriber identification module (SIM) user equipment (UE) in a wireless communication network through non-3rd generation partnership project (N3GPP) access. The method comprises the steps of: determining, by a multi-SIM UE, a service in progress on a first SIM of a multi-SIM UE through 3GPP access; and managing MT service information for a second SIM of a multi-SIM UE using N3GPP access based on the service in progress for the first SIM of the multi-SIM UE's 3GPP access by a multi-SIM UE.

Description

Method and device for managing MT service information The present disclosure relates to wireless communication, and more specifically, the present disclosure relates to a method for managing mobile terminated (MT) service information through non-3rd generation partnership project (N3GPP) access in a wireless communication network and to multi-subscriber identity module (SIM) user equipment (UE). Efforts have been made to develop advanced 5th generation (5G) or pre-5G communication systems to meet the demands resulting from the continuously increasing wireless data traffic following the commercialization of 4th generation (4G) communication systems. For this reason, 5G or pre-5G communication systems are also referred to as beyond 4G network communication systems or post-LTE (long term evolution) systems. Implementations of 5G communication systems using ultra-frequency millimeter wave (mmWave) bands, such as the 60 GHz band, are considered to achieve higher data transmission rates. To reduce propagation loss of radio waves and extend transmission range in ultra-frequency bands, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and large-scale antenna techniques are under discussion. To improve system networks, technologies for next-generation small cells, cloud RANs (radio access networks), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, moving networks, cooperative communication, coordinated multi-points (CoMP), and receiver interference cancellation are also being developed in 5G/NR communication systems. In addition, advanced coding modulation (ACM), such as hybrid frequency-shift keying (FSK) and quadrature amplitude modulation (QAM) (FQAM), sliding window superposition coding (SWSC), and advanced access technologies, such as filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA), are being developed in 5G systems. Meanwhile, the Internet is evolving from a human-centric connectivity network where humans generate and consume information into the Internet of Things (IoT), where distributed entities, such as objects, transmit, receive, and process information without human intervention. For example, the Internet of Everything (IoE) has also emerged, combining IoT with big data processing technologies through connections with cloud servers. To implement IoT, various technologies are required, including sensing technology, wired and wireless communication and network infrastructure, service interfacing technology, and security technology. Recently, even technologies for sensor networks, machine-to-machine (M2M), and machine-type communication (MTC) for connecting objects are being researched. This IoT environment can provide intelligent Internet Technology (IT) services that create new value for human life by collecting and analyzing data generated between connected objects. IoT can be applied to various fields such as smart homes, smart buildings, smart cities, smart or connected vehicles, smart grids, healthcare, smart home appliances, and next-generation medical services through convergence and combination between existing information technology (IT) and various industrial applications. In this regard, various attempts are being made to apply 5G communication systems to IoT networks. For example, technologies related to sensor networks, M2M, MTC, etc., are implemented by 5G communication technologies, such as beamforming, MIMO, and array antenna schemes. Even the application of the aforementioned cloud radio access network (cloud RAN) as a big data processing technology can be seen as an example of the convergence of 5G and IoT technologies. Generally, due to technological advancements, multi-subscriber identification module (SIM) user devices (UEs) are widely used to obtain the benefits of services from various operators. Consider a multi-SIM user device (UE) with a single receiver and transmitter, or a multi-SIM UE with dual receivers and a single transmitter. The multi-SIM UE is in connection mode using services on the first SIM of the multi-SIM UE via 3GPP access. The multi-SIM UE receives paging from the network for the second SIM. The multi-SIM UE does not have knowledge of what kind of service is pending for the second SIM. Therefore, the multi-SIM UE responds to the paging via 3GPP access and enters connection mode via 3GPP access by interrupting the service in progress on the first SIM. After entering connection mode, the multi-SIM UE notices that the service on the second SIM does not take precedence over the service that was in progress on the first SIM. Therefore, multi-SIM UEs will have to abandon services on the second SIM and fall back to services on the first SIM via 3GPP access. This will have a significant impact on services on the first SIM on the UE side (e.g., reduced throughput). At the same time, the network will face
