BACKGROUND

1. Field

The embodiments herein relate to wireless communication, and more particularly, to a method and a user equipment (UE) for optimizing resources of wireless communication network while providing 5 th generation (5G) services.

2. Description of the Related Art

To meet the demand for wireless data traffic having increased since deployment of 4G communication systems, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a âBeyond 4G Networkâ or a âPost LTE Systemâ. The 5G communication system is considered to be implemented in higher frequency (mmWave) bands, e.g., 60 GHz bands, so as to accomplish higher data rates. To decrease propagation loss of the radio waves and increase the transmission distance, the beamforming, massive multiple-input multiple-output (MIMO), Full Dimensional MIMO (FD-MIMO), array antenna, an analog beam forming, large scale antenna techniques are discussed in 5G communication systems. In addition, in 5G communication systems, development for system network improvement is under way based on advanced small cells, cloud Radio Access Networks (RANs), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, moving network, cooperative communication, Coordinated Multi-Points (CoMP), reception-end interference cancellation and the like. In the 5G system, Hybrid FSK and QAM Modulation (FQAM) and sliding window superposition coding (SWSC) as an advanced coding modulation (ACM), and filter bank multi carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) as an advanced access technology have been developed.

The Internet, which is a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of Things (IoT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of Everything (IoE), which is a combination of the IoT technology and the Big Data processing technology through connection with a cloud server, has emerged. As technology elements, such as âsensing technologyâ, âwired/wireless communication and network infrastructureâ, âservice interface technologyâ, and âSecurity technologyâ have been demanded for IoT implementation, a sensor network, a Machine-to-Machine (M2M) communication, Machine Type Communication (MTC), and so forth have been recently researched. Such an IoT environment may provide intelligent Internet technology services that create a new value to human life by collecting and analyzing data generated among connected things. IoT may be applied to a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services through convergence and combination between existing Information Technology (IT) and various industrial applications.

In line with this, various attempts have been made to apply 5G communication systems to IoT networks. For example, technologies such as a sensor network, Machine Type Communication (MTC), and Machine-to-Machine (M2M) communication may be implemented by beamforming, MIMO, and array antennas. Application of a cloud Radio Access Network (RAN) as the above-described Big Data processing technology may also be considered to be as an example of convergence between the 5G technology and the IoT technology.

Currently, with the advancement in wireless communication technology, number of users accessing a wireless communication network has increased manifold times. The increased number of users of the wireless communication network has also brought in the need for optimizing resources of the wireless communication network to be able to serve the increased number of users.

Consider an example scenario where a user equipment (UE) which is dual subscriber identity module (SIM) and dual radio capable with a first transceiver being allocated to a first SIM and a second transceiver being allocated to a second SIM. When a call is initiated one the first SIM, then the second SIM is moved into an idle state with a data connectivity being suspended. However, due to the suspension of the second SIM, the second transceiver remains un-utilized which leads to loss of resources of the wireless communication network.

In another example scenario, consider the UE is dual subscriber identity module (SIM) and has a single transceiver. When the UE receives the call on the first SIM, then transceiver is allocated to the first SIM without informing the second SIM. Since, the second SIM is not aware about the call on the first SIM, the paging on the second SIM continues leading to un-necessary power consumption, which is not addressed.

The above information is presented as background information only to help the reader to understand the present invention. Applicants have made no determination and make no assertion as to whether any of the above might be applicable as prior art with regard to the present application.
