Description

Method and system for aggregating and exchanging messages in an IoT communication system Technical Field The present disclosure relates to the field of internet of things (IoT) communications, and in particular to message aggregation and exchange in IoT communication systems. Background In order to meet the demand for increased wireless data traffic since the deployment of fourth generation (4G) communication systems, efforts have been made to develop improved fifth generation (5G) or former 5G communication systems. Therefore, the 5G or front 5G communication system is also referred to as a "super 4G network" or a "LTE-after-system". A 5G communication system is considered to be implemented in a higher frequency (mmWave) band (e.g., 60GHz band) in order to achieve a higher data rate. In order to reduce propagation loss of radio waves and increase transmission distance, beamforming, massive Multiple Input Multiple Output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, massive antenna techniques are discussed in 5G communication systems. Further, in the 5G communication system, development of system network improvement is underway based on advanced small cells, cloud Radio Access Networks (RANs), ultra dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, cooperative multipoint (CoMP), reception-side interference cancellation, and the like. In 5G systems, hybrid FSK and QAM modulation (FQAM) and Sliding Window Superposition Coding (SWSC) as Advanced Coding Modulation (ACM) and Filter Bank Multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code division multiple access (SCMA) as advanced access technologies have been developed. The messaging service, MSGin G service, is defined by the third generation partnership project (3 GPP) in5G systems, which is capable of implementing various messaging models with advanced messaging (messaging) service capabilities and capabilities over 5G systems. MSGin5G services support messaging models such as point-to-point messaging, application-to-point messaging, group messaging, and broadcast messaging. In addition, MSGin G services are basically designed and optimized for message communications between massive internet of things (MIoT) devices, including object-to-object communications and person-to-object communications. Typical IoT devices communicate send and receive small data, which may be delivered in messages. However, the features of MIoT devices, such as, but not limited to, high density connections, flexible mobility, limited power-saving computing power, large numbers of devices, traffic patterns of short bursts of small data, etc., bring about various new demands for messaging. Examples of new requirements may be, but are not limited to, requirements for lightweight messaging for provisioning and monitoring, ultra low latency and high reliability messaging for remote control, extremely high resource efficiency for large scale connections, etc. According to one requirement, the MSGin G service must optimize resource utilization for both the control plane and the user plane in a resource efficient manner in view of the high throughput of message communications between MIoT devices and MIoT devices or MIoT devices and application servers. MIoT devices may have limitations in terms of computation and storage, and may use batteries or small solar photovoltaic devices, so that message communication must be lightweight and well-scheduled in order to save power and data traffic consumption of MIoT devices. In addition, MIoT devices may send data that is significantly smaller than the maximum segment size that can be transmitted over the available transmissions. However, in such a scenario, if a greater number of messages exchanged between MIoT devices are used to send and receive data that is significantly smaller than the maximum segment size, the control plane and user plane resources may not be fully utilized. Furthermore, exchanging a greater number of messages between MIoT devices for transmitting and receiving data that is significantly smaller than the maximum segment size may result in a significant amount of overhead. In addition, a greater number of messages may be exchanged between MIoT devices and application servers for data that is significantly smaller than the maximum segment size. In such a scenario, control plane and user plane resources may not be fully utilized. Disclosure of Invention Technical problem It is a primary object of embodiments herein to disclose methods and systems for aggregating and exchanging messages in an internet of things (IoT) communication system. It is another object of embodiments herein to disclose a method and system for aggregating multiple message requests into a single message request and transmitting the single message request to at least one target device, wherein the size of each message request is less than a
