BACKGROUND
The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.
The Internet of Things (IoT) is a network of devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity which can be readable, recognizable, locatable, addressable, and controllable via an IoT communications network that enables these things to connect and exchange data, creating opportunities for more direct integration of the physical world into computer-based systems, resulting in efficiency improvements, economic benefits, and reduced human exertions. The “Internet of things” (IoT) concept is getting more and more popular, and devices, such as sensors, actuators and everyday objects including the coffee makers, washing machines, headphones, lamps and wearable devices, etc. are being increasingly looked upon as potential IoT devices. IoT involves extending Internet connectivity beyond standard devices, such as desktops, laptops, smartphones and tablets, to any range of traditionally dumb or non-internet-enabled physical devices and everyday objects. Embedded with technology, these devices can communicate and interact over the Internet, and they can be remotely monitored and controlled. The term "Enterprise IoT" refers to devices used in business and corporate settings in a network of physical objects that contain

embedded technology to communicate and sense or interact with their internal states or the external environment. Here, IoT refers to Internet-connected physical devices, in many cases everyday objects (things) that can communicate their status, respond to events, or even act autonomously. This enables communication among those things, closing the gap between the real and the virtual world and creating smarter processes and structures that can support us without needing our attention. IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS), and the Internet. An IOT device is generally provisioned with an IP address to provide it with the capability of transferring data and receive control signals over an IP network using the standard Internet protocols such as TCP/IP which is being exclusively used in the Internet.
With the IoT concept getting more and more popular, devices, such as sensors, actuators and everyday objects including the coffee makers, washing machines, headphones, lamps and wearable devices, smart metering, child monitoring etc. are being increasingly looked upon as potential IoT devices. An IOT device is generally provisioned with an IP address to provide it with the capability of transferring data and receive control signals over an IP network using the standard Internet protocols such as TCP/IP which is being used in the Internet.
Recently, 3GPP has introduced a new technology NB-IoT in release 13. The low end IoT applications can be met with this technology. This technology has better performance than Low Power Wide Area Networks (LP-WAN). It has taken efforts to address IoT markets with completion of standardization on NB-IoT. The NB-IoT technology has been implemented in licensed bands of LTE, which are used for exploiting this technology. This technology makes use of a minimum system bandwidth of 180 KHz i.e. one PRB (Physical Resource Block) is allocated for this technology. The NB-IOT can be seen as a separate RAT (Radio Access Technology). The NB-IOT can be deployed in 3 modes: “in-band”, “guard band” and “standalone”. In the “in-band” operation, resource blocks present within LTE

carrier are used. The inner resource blocks are not used as they are allotted for synchronization of LTE signals. In “guard band” operation, resource blocks between LTE carriers that are not utilized by any operator are used. In “standalone” operation, GSM frequencies are used or possibly unused LTE bands are used. Release 13 contains important refinements like extended or enhanced discontinuous reception (eDRX) and power save mode (PSM). The PSM ensures battery longevity in release 12 and is completed by eDRX for devices that need to receive data more frequently.
The NB-IoT technology focuses on devices like meter reading of water and electricity consumption that are stationery. Some of the use cases are: facility management services, fire alarms for home and commercial properties, tracking of persons and objects. The industries where NB-IoT services can add value are: Smart city, smart home, Safety and security, agriculture, health care and Energy. Another example for IoT industry includes logistic tracking. The tracking devices on shipping containers send huge volumes of sensor data that are collected and taken for analysis in order to make sure that real-time tracing of shipment locations can be made possible. The output display units are used for receiving alerts and optimized with service recommendations.
The NB-IoT technology addresses some of the key IoT requirements.
• Battery lifetime of the devices increases.
• Improved network coverage.
• Cost of the devices is reduced
• Multiplexing of devices met for capacity requirements.
• Support massive number of devices
• Low power consumption
• Use of low-cost devices

. Provides excellent coverage.
In a NB-IOT deployment, the NB-IOT cells have a 20db gain over other categories like CAT-1 cells. As such, the NB-IOT Carrier can support much larger areas when compared to a CAT-1 base station or channel. Typically, in NB-IOT scenario, the same base station provides the NB-IOT channels for a device. The same or a different base station can provide a channel for a CAT-1 or a CAT-4 operation due to the difference in the NB-IOT and other category cell coverage areas.
As huge number of IoT devices are connected and as businesses use applications to parse IoT data, connectivity becomes a real concern for both the CAT 1 and the CAT NB-IoT. When it comes to IoT ecosystem development, limited network bandwidth could be the weak link in the chain as latency stifles progress.
As IoT UEs may require to perform service-based requirement such as Firmware Over-the-Air (FOTA) upgrade from time to time, there is a challenge for such service-based requirement if the service requirement need high bandwidth. In such case, the IoT UEs should be able to latch on the high bandwidth RATs for faster and quicker service delivery and it would be better to switch to CAT-1 for such service like FOTA upgrade as CAT NB-IoT only supports lower DL data rate in the order of kbps.
The current 3GPP specification Release 13 does not specify any method for IoT Device to select the other high bandwidth RATs when there is need to download large data files. The specification does not define any solution on how the IoT UE may be able to latch on the high bandwidth RATs for faster and quicker service delivery. There is primarily a challenge for latching on the high bandwidth RATs for faster and quicker service delivery and this is necessary as the high bandwidth channel will help to provide efficient way of connectivity to billions of devices that has to be managed efficiently to handle service requests. Also, as the numbers grows for the IoT devices in future there needs to be an efficient architecture for latching on the high bandwidth RATs for faster and quicker

service delivery.
Thus, there exists a need in the art to find a solution for a system and method to support latching on the high bandwidth RATs (CAT-1/4) for faster and quicker service delivery so that the high bandwidth channel will help to provide efficient way of connectivity to billions of devices that has to be managed efficiently to handle service requests.
Therefore, in view of the above shortcomings in the existing approaches, there is a need in the art to provide a more efficient solution of switching from CAT-NB channel to CAT-1/4 channel for high data rate services.

The method may further comprise that in response to the high data rate service requirement, the network entity [300] transmits an acknowledgement signal corresponding to the high data rate service requirement received from the user equipment [200]. The said step of transmitting high data rate service requirement via the narrow band channel, and receiving an acknowledgement signal thereof, may occur prior to the step of the user equipment [200] transmitting a a RRC connection request to the network entity [300].
Referring to FIG. 7, an exemplary flow diagram [700] depicting an exemplary method for implementation of RRC connection request for legacy network, in accordance with exemplary embodiments of the present disclosure.
The example encompasses that the method begins at step [702].

Thereafter, the user equipment [200] receives a list of neighbouring CAT-1/4 channels from the network entity [300]. The list comprises at least one available neighbouring CAT-1/4 channel information and a channel identifier associated with each of the at least one available neighbouring CAT-1/4 channel. The

method may further comprise storing by the user equipment [200] list of neighbouring CAT-1/4 channels in a database.
Subsequently, the user equipment [200] switches from the narrow band channel to one of the available CAT-1/4 channel based on at least the list of neighbouring CAT-1/4 channels received from the network entity [300] and in response to a high data rate service requirement. Once the high data rate service requirement has been fulfilled, the user equipment [200] may switch back to the narrow band channel. For instance, once FOTA upgrade has been completed, the user equipment [200] may switch back to the narrow band channel.
Referring to FIG. 8, an exemplary flow diagram [800] depicting an exemplary method for implementation of piggyback neighbour cell information request, in accordance with exemplary embodiments of the present disclosure.
The example encompasses that the method begins at step [802]. The user equipment [200] may be operating in an idle mode and power saving mode (PSM). At step [806], the user equipment [200] initiates reattach with the network entity [300] via Tracking Area Update (TAU) procedure after PSM cycle is timed out. In idle mode, the user equipment [200] may be configured to send period tracking area update message to the wireless network in order to indicate the current Tracking Area (TA) in which the user equipment [200] is currently located.
At step [808], along with the TAU signals, the user equipment [200] requests for CAT-1 Neighbour cell information by transmitting the RRC connection request to the network entity [300] via the TAU procedure as an additional update type, for instance, spare bits in the TAU signal can be used. During RRC connection request, the user equipment [200] may include the cause Piggyback Neighbour cell information request along with TAU signaling.
Upon completion of the TAU procedure, the network entity [300] transmits a list of neighbouring CAT-1/4 channels to the user equipment [200]. The list may be

received in the RRC connection release message. The list comprises at least one available neighbouring CAT-1/4 channel information and a channel identifier associated with each of the at least one available neighbouring CAT-1/4 channel. The method may further comprise storing by the user equipment [200] list of neighbouring CAT-1/4 channels in a database.
Thereafter, whenever the user equipment [200] requires to fulfil high data rate service requirement, the user equipment [200] refers to the list stored in the database and switches from the narrow band channel to one of the available CAT-1/4 channel based such stored list. Once the high data rate service requirement has been fulfilled, the user equipment [200] may switch back to the narrow band channel. For instance, once FOTA upgrade has been completed, the user equipment may switch back to the narrow band channel.
Therefore, as evident from the above method, the user equipment [200] can easily switch from CAT-NB to CAT 1/3/4 channel when a high data rate service request is received since the list of available CAT 1/3/4 channels are already stored at the user equipment [200]. This avoids unnecessary signaling between the user equipment [200] and the network entity [300] when a high data rate service request is received.
FIG. 9 illustrates an exemplary flow diagram [900] depicting an exemplary method for implementation of periodic measurement of neighbouring list, in accordance with exemplary embodiments of the present disclosure.
The method starts at step [902]. At step [904], the user equipment [200] may be currently camped on a NB Cell/ channel.
The method at step [906] comprises periodically receiving at the network entity [300] a periodic neighbor list request from the user equipment [200] comprising at least a user equipment [200] identifier and a request for neighbouring CAT-1/4 channels information. The network entity [300] transmits a list of neighbouring CAT-1/4 channels to the user equipment [200]. The list comprises at least one

available neighbouring CAT-1/4 channel information and a channel identifier associated with each of the at least one available neighbouring CAT-1/4 channel.
Subsequently, the user equipment [200] periodically measures the at least one parameter associated with the CAT-1/4 channels as provided in the list of CAT-1/4 channels received from the network entity [300]. For instance, the user equipment [200] measures SNR, attenuation, bit rate for each of the channels contained in the list of CAT-1/4 channels received from the network entity [300]. The user equipment [200] then generates a measurement report comprising at least the channel identifier and the at least one parameter associated with the at least one CAT-1/4 channels, and transmits said measurement report to the network entity [300].
Thereafter, whenever the user equipment [200] requires to fulfil high data rate service requirement, the user equipment [200] refers to the list stored in the database and switches from the narrow band channel to one of the available CAT-1/4 channel based on at least the list of neighbouring CAT-1/4 channels received from the network entity [300] and in response to a high data rate service requirement. Once the high data rate service requirement has been fulfilled, the user equipment [200] may switch back to the narrow band channel. For instance, once FOTA upgrade has been completed, the user equipment [200] may switch back to the narrow band channel.
Therefore, as evident from the above method, the user equipment [200] can easily switch from CAT-NB to CAT 1/3/4 channel when a high data rate service request is received since the list of available CAT 1/3/4 channels are already stored at the user equipment [200]. This avoids unnecessary signaling between the user equipment [200] and the network entity [300] when a high data rate service request is received.
Therefore, as is evident from the above disclosure, the present invention provides mechanisms to switch a user equipment [200] from a CAT-NB channel

to a CAT 1/3/4 channel whenever there is a high data rate service requirement. For instance, when a firmware upgrade is required to be performed, it is more efficient for the user equipment [200] to switch from CAT-NB to CAT 1/3/4 channel so as to avail a higher bandwidth and better speed. Similarly, for instance, if the user equipment [200] is a camera in a smart home that detects the presence of an unknown individual and is configured to start recording a video and send the same to the user. In such a case, the present invention facilitates the camera to switch from CAT-NB channel to a CAT 1/3/4 channel so as to efficiently send the video recording in real-time to the user.
Although the above description has been described for switching between CAT NB-IoT channel to CAT-1 channel, it will be appreciated by those skilled in the art that the techniques described herein can be used for providing switching of a user equipment [200] from a CAT-NB channel to a CAT-1, or CAT-4 channel.
