LTE Location Technologies and Delivery Solutions

With the rapid growth of mobile communication systems, user location is proving to be an important asset for end users, operators, application service providers, enterprises, public safety and law enforcement officials, and others. There are a vast number of applications and use cases that exploit location capabilities but with a diverse set of needs and requirements in terms of accuracy, latency, scalability etc. Long Term Evolution (LTE) offers multiple methods for determining and delivering location information. The chosen method must meet and be tailored to the needs of the application and use case for which it is being designed. In this paper, location determination and delivery methods in LTE, realizable and simple network architectures to support them, and a comparative analysis and recommendations of these methods are discussed. Furthermore, several representative uses case, their requirements, and solutions for them are also addressed.
