2. Description of Related Art

In order to meet the increasing demands for wireless data since the deployment of 4th-Generation (4G), communication systems, efforts were made to improve the 5th Generation (5G) or pre-5G communications network. Thus, the 5G or pre-5G communications system can also be referred to as a “Beyond 4G Network” or an “Post LTE System”. The 5G communications system is considered to be implemented with higher frequencies (mmWave) bands, e.g., 60 GHz bands, to accomplish higher data rates. Todecrease propagation loss of the radio waves and increase the distance of transmission, beamforming, massive multiple-input multiple-output (MIMO) and full-dimensional MIMO (FD-MIMO), array antenna, an analog beam-forming technique, and large-scale antenna techniques are being discussed in 5G communication systems. The development of 5G communication technology is based on the latest small cell, cloud radio access networks (RANs), ultra dense networks, device to device (D2D), wireless backhaul, and moving networks. This includes cooperative communications as well as coordinated multiple-points (CoMP), reception end interference cancellation, and other such technologies. As an advanced access technology, 5G systems will use hybrid FSK/QAM modulation (FQAM), sliding window superpositioncoding(SWSC) and filter bank multi carrier (FBMC) as well as sparse code multiple accessibility (SCMA), and non-orthogonal multiple acces (NOMA) to offer coding modulation (ACM).

Internet is a human-centered connectivity system that allows humans to create and consume information. However the Internet of things (IoT), where distributed entities such as things can exchange and process information without human intervention is in the process of evolving. The Internet of everything (IoE), which is a combination of the IoT technology as well as the huge data processing technology via connection to a cloud server has come into existence. 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. This type of IoT environment may provide intelligent Internet technology that adds the possibility of a brand new value to human life by collecting and analyzing data generated among connected things. IoT can be used in a wide range of fields, including smart home and smart cities, smart buildings, connected cars or smart cars and smart grids as well as health care and medical technology. It’s possible to integrate the existing technology of information technology (IT) with other industrial applications.

There have been numerous attempts in this direction, to use 5G communication systems to support IoT networks. For instance, technology such as a sensor network machine type communication (MTC), and machine-to-machine (M2M) communication may beimplemented through beamforming, MIMO, and array antennas. The use of a cloud radio access network (RAN) as described above big data processing technology could be considered as an illustration of the convergence of 5G technology and the IoT technology.

As a variety of services are delivered with the development of wireless communication systems , as described above, schemes to provide these services efficiently are required.

This background information is provided to aid in understanding the disclosure. There is no determination or any assertion has been made, as to whether any of these might be applicable as prior art, in connection with the disclosure.

The disclosure’s objectives are to address at least the problems mentioned above or drawbacks and provide at least the advantages described below. A method of efficiently measuring the strength of wireless signals in the communication system is an aspect of the disclosure.

A third aspect of the disclosure is that it offers an opportunity to rapidly recover from failure using an alarm clock within a wireless communication network.

Other aspects are described in part in the description that follows and in part will be apparent from the description, or could be learned through practicing the embodiments described.

In accordance with the disclosed aspect in the event that the base station transmits an indication of signal strength to a terminal, when a condition of the given configuration is met, the terminal transmits the strength of aserving cell, as well as the strength the neighboring cell, but the strength transmission is not applicable to all cells in the vicinity, and can only be to a neighboring cell operating at a frequency that is similar to the serving cell to where a serving cell measurement object is set up.

According to another aspect of disclosure, the terminal can operate an wireless signal timer through strength measurement of a downstream signal, then if a handover target cells is found the timer will be reset with a short timer value that could be used as serving cells. If a handover operation message is not received within the specified time and the terminal declares failure.

In accordance with a different aspect of the disclosure, during the time of measuring signal strength in a mobile communication system, the measurement object of a serving cell is restricted to a neighboring cell in a restricted frequency, ratherthan measuring the signal strength of all the potential neighboring cells, so that the amount of information produced by sending measurement data of an unnecessary neighboring cell is reduced.

According to another aspect of disclosure In the event there is no other alternative than transfer to a different cell via quick failure announcement in addition to time for monitoring the signal strength of serving cells is eliminated to allow fastfailure recovery.

The detailed description that follows will allow you to understand the other advantages, aspects, and key features of the disclosure. It is accompanied by the attached drawings.

What is a patent?

Patents are issued by the government in order to protect the invention. It grants the inventor the sole right to develop, utilize and market the invention. Society benefits when new technology is introduced for sale. Benefits can be realized in the direct sense, since it may allow people to accomplish previously unattainable things, or indirectly by the economic benefits (business growth and job opportunities) which the invention provides.

Patent protection is sought by many universities and pharmaceutical companies for research and development. Patents can be granted to a product, process, or method for making new materials. In order to be granted protection under a patent the invention must be useful, new, and not obvious to others within the same field.

Patents give inventors a reward for commercially profitable inventions. They are an incentive to inventors to come up with new ideas. Small-scale businesses and inventors are assured that they will get the most return from the investment they make in technology development through patents. They can earn a living from their work.

Patents play a vital role in businesses with the ability to:

Protect the latest products and services;

Your products will be more prominent as well as valuable and appealing to buyers.

Make your company and products stand out from the competition;

Find business and technical information.

Beware of accidentally using content from third parties or losing important information, original outputs, or any other creative output.

Patents transform inventor’s knowledge into a valuable asset which creates new opportunities for employment creation through joint ventures and licensing.

Small-scale businesses with patent protection will be more appealing to investors in the commercialization and development of technology.

Patenting can lead to the development of fresh ideas and innovative inventions. This information could be protected by patents.

Patents can serve as a deterrent to untrustworthy third parties that profit from the invention’s success.

Patent-protected technology revenue that is commercially viable can be used for financing technological research and development (R&D) which will improve the chances for better technology in the future.

Intellectual property ownership can be used to convince investors and lenders that there are legitimate chances to commercialize your product. Sometimes, one powerful patent can open the door to numerous financing possibilities. Patents can be used along with other IP assets as collateral or security for financing. Investors may also be able to see your patent assets to increase the value of your company. Forbes and others have pointed out that every patent can boost the value of your company by as much as $500,000 to $1 million.

Start-ups need a well-constructed business plan that builds on the IP to demonstrate that your product or service is unique and superior or ingenuous. Investors are also impressed if you have IP rights are secure or are in the process of becoming secure and if they are supportive of your business strategy.

It is essential to keep your invention secret until you apply for patent protection. Making an invention public before filing it could often erode its originality and render it patent-infringing. The filing of disclosures prior to filing, for example, for investors, test-marketing or other business partners should be done only after the signing of a confidentiality contract.

There are several types of patents, and understanding these is vital to safeguard your invention. Utility patents cover new processes and machine creations. Design patents cover ornamental designs. Utility patents are the best because they shield the owner from copycats and other competition. In most cases the utility patents are granted for improvements or modifications on existing inventions. Utility patents also cover enhancements and modifications in existing inventions. A process patent will be a way to describe the actions or methods of performing a particular act. But, a chemical composition would include an amalgamation of ingredients.

What is the typical length of a patent? Utility patents last 20 years from the initial date of filing, however their expiration dates can be extended due to delays at the patent office, for example.

When the patent office is satisfied with your application, you’ll be able to conduct a patent number look to locate the patent issued. Your product now has the potential to be patentable. Alongside the USPTO search engine, you may also use other search engines, such as espacenet, as detailed below. A patent lawyer or patent attorney can advise you on the process. In the US Patents are issued by the US trademark and patent office, or the United States patent and trademark office, which is also responsible for examining trademark applications.

Are you looking for similar patents? These are the steps:

1. Brainstorm terms to describe your invention, based on its purpose, composition, or use.

Write down a brief and precise description of the invention. Avoid using generic terms such as “device”, “process,” or “system”. Instead, consider synonyms to the terms you initially chose. Then, take note of important technical terms and keywords.

Utilize the following questions to help you find key words or concepts.

  • What is the goal of the invention Is it a utilitarian device or an ornamental design?
  • Is inventing a method to create something or perform an action? Does it constitute an item?
  • What is the purpose and composition of the invention? What is the physical constitution?
  • What’s the objective of this invention?
  • What are the technical terms and terms used to describe the nature of an invention? To assist you in finding the appropriate terms, use an online dictionary of technical terms.

2. Use these terms to find pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. If you are unable to determine the correct classification for your invention, look through the class Schemas (class schedules). If you don’t see any results from the Classification Text Search, you might consider substituting your words that describe your invention using synonyms.

3. Go through 3. Check the CPC Classification Definition for confirmation of the CPC classification you have found. If the chosen classification has a blue box with a “D” to its left, clicking on the link will lead you to the CPC classification’s description. CPC classification definitions can help determine the relevant classification’s scope and therefore you’re certain to pick the most appropriate. These definitions may also include some search tips or other recommendations that could be helpful for further investigation.

4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. By focusing your search on abstracts and illustrations you can narrow your search to the relevant patent documents.

5. Utilize this selection of most relevant patent publications to look at each in detail for similarities to your invention. Pay attention to the specification and claims. You may find additional patents through contacting the patent examiner and applicant.

6. Search for patent applications that have been published using the CPC classification you selected in Step 3 of the Applications Full-Text and Image Database. You can apply the same method of search as Step 4, narrowing your search results to the most pertinent patent applications through the abstract and drawings that appear on each page. After that, take a close look at the patent applications that have been published with particular attention paid to the claims as well as additional drawings.

7. Find additional US patent publications using keyword searches in the PatFT and AppFT databases, searching for classification of non-U.S. patents using the below, and searching for non-patent publications of inventions with web search engines. Here are a few examples:

  • Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
  • Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
  • Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
