5G mobile phone concept is a concept that will have a software technology that defines the radio and modulation schemes as well as new error control scheme (New Error-Control Schemes) which can be downloaded via the internet. This development was seen was headed toward the user’s connection as the focus of this 5G mobile phone concept. Connections are able to access to different wireless technologies at the same time and the connection is able to combine the different currents of different technologies as well.
The 5G technology, each network will be responsible for handling the user’s movement, while the connection will determine the final choice between different wireless and mobile access network service providers for certain services. That choice will be based on the middleware is installed on a cell phone.
Wireless networks have grown very rapidly in the last 15 years. On this day, many mobile phones equipped with a WLAN adapter, and most likely the future of all mobile phones will also be equipped with WiMax adapter. In the 2G and 3G technology, which uses Internet Protocol (IP) on the one hand, and WLAN (Wireless Local Area Network) on the other hand, has been increasing research activity on the incorporation of these technologies.
On 4G technology, the focus of these technologies led to the incorporation of cellular networks like GSM and 3G, WLAN and Bluetooth. Users multimode connections as shown must have a 4G, but the different security mechanisms and support different QoS in different wireless technologies also remains a challenge. Merging the two technologies in different wireless networks are still running even to this day.
However, different wireless networks from a single connection is used exclusively, meaning that no combination of different wireless access technologies in the same session. Open Wireless Architecture (OWA) is proposed, targeted to open baseband processing module with the parameters of an open interface to support the existence of differences as well as the future standard of wireless communication. OWA is targeted to layer MAC / PHY on cellular connections in the future. The above explanation is the background of the concept of 5G cellular network.
Physical Layer / MAC
Physical and Medium Access Control (MAC / PHY) is the first layer and second layer of the OSI (Open Systems Interconnect) which defines the wireless technology. In the second layer, the 5G cellular network tends to be based on Open Wireless Architecture (OWA).
Layer of the network used is most likely the IP (Internet Protocol) because no one else that can compete with the IP. Internet Protocol version 4 (IPv4) has spread almost all over the world and have some addressing issues such as limited space and lack of a definite possibility for QoS in support of each stream. These issues have been solved by IPv6, but IPv6 packet header traded with far greater. This makes the movement still has problems.
All mobile networks will use IP phones in the 5G, and any cellular connection using the FA (Foreign Agent), CoA (Care of Address) equipment to map the IPv6 fixed address and CoA address for the wireless network is now used. Phones can be attached to multiple cellular or wireless network at the same time. In some cases, it can maintain IP addresses are different for each radio interface, while each IP address will be for the FA CoA address placed on a cell phone. IPv6 has been enhanced to be applied on a cell phone 5G. 5G mobile phone will keep the wireless multivirtual network environment.
To that end, the network layer must be divided into two sub layers in the 5G cellular network, the Lower Network Layer (for each interface) and Upper Layer Network (for a cellular connection). The division is because the initial design of the internet, where all the routes based on IP addresses that should be different in each IP networks around the world. Middleware between the upper and lower layers of the network will retain the address of the network address translation upper (IPv6) to the IP address of a different lower network (IPv4 or IPv6), and vice versa.
Open Transport Layer Protocol (OTA)
Cellular and wireless networks differ from wired networks associated with the transport layer (Transport Layer). In all versions of TCP, segments are lost due to the blockage of the network, while on the wireless network, the loss of the segment is likely to occur due to error ratio is slightly larger in the radio interface. Therefore, the proposed TCP modification and adaptation for mobile and wireless networks, which sends back the parts are missing or damaged TCP is done only through a wireless link. For 5G phones, the connection would be appropriate to have a transport layer that allows it to be downloaded and installed. Each cell must have the ability to download such as TCP, RTP, or new transport protocol that is targeted to a specific wireless technology installed at the BTS. This is called Open Transport Protocol (OTP).
Speaking about the application, the main message of the 5G cellular connection is to provide intelligent QoS management through a diverse network. Today, in the mobile phone user can manually select the wireless interface to a particular internet service without having the ability to use the QoS history to choose the best wireless connection to a particular service. 5G telephone service must provide the ability for quality testing and measurement of information storage in the database of information on cellular connections. QoS parameters such as delay, loss, wide band, reliability, will be deposited into the cell phone database 5G with a view used by intelligent algorithms that run on cellular connections as a processing system, which in turn should provide the best wireless connection to one’s limitations and costs QoS is required.
5G mobile phone concept is proposed as an open platform designed in different layers, from physical layer to application layer. The proposed concept of adjusting to the Open Wireless Architecture (OWA) that have been proposed for 4G mobile connections, and provide the changes are more distant from the network layer to application layer.
The network layer is divided into two sub-layers to provide all IP connectivity in an environment surrounded by cellular or wireless technologies such as network providers and service providers. Open transport layer is proposed in order to allow the use of specific implementations of the protocol-protocol wireless carrier. 5G mobile phone concept is also possible to select a different wireless technologies to include the cost of QoS constraints on the services of different QoS, real-time (VoIP, streaming, IPTV, etc.) or non-real-time (web, messaging, games , etc.).
To that end, 5G cellular network connection should be able to maintain a database that will store statistical information relating to services and wireless technologies available on the phone. At this time, the ongoing development of these modules is capable of providing the best QoS with the lowest prices for certain services provided using one or more wireless technologies at the same time from a cell phone 5G
