Description

[Technical Field] The invention is according to the independent claims, and relates to wireless communication. More particularly, the disclosure relates to a service enabler architecture layer (SEAL) system and a method for provisioning inter-services communication in the SEAL system of wireless communication network. [Background Art] To meet the demand for wireless data traffic having increased since deployment of 4th generation (4G) communication systems, efforts have been made to develop an improved 5th generation (5G) or pre-5G communication system. The 5G or pre-5G communication system is also called a 'beyond 4G network' or a 'post long term evolution (LTE) system'. 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, beamforming, massive multiple-input multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large-scale antenna techniques are discussed with respect to 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 frequency shift keying (FSK) and Feher's quadrature amplitude 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 "sensing technology", "wired/wireless communication and network infrastructure", "service interface technology", and "security technology" 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, MTC, and M2M communication may be implemented by beamforming, MIMO, and array antennas. Application of a cloud 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. As described above, various services can be provided according to the development of a wireless communication system, and thus a method for easily providing such services is required. Generally, telecom industry mainly serves consumers with mobile communications including call, text, and internet data. However, the telecom industry is fast evolving and ready to offer services to different verticals (such as Public Safety, Automotive, Health, Logistics etc.) based on the demand from the verticals to leverage the telecom network in respective domains. Therefore, the telecom networks now need to support different service delivery characteristics for different kinds of services. In general, the service verticals when deployed over the telecom network would be disconnected and work in isolation. Multiple of such service verticals would require similar network functionalities. Existing model of isolated service verticals does not allow convergence of the similar network functionalities, which might lead to loss of resources and processing speed especially when there are a large number of service verticals requesting for the services from the telecom networks. The above information is presented as background information only to assist with an understanding the disclosure. No determination has been made and no assertion is made, as to whether any of the above might be applicable as prior art with r
