Efficient Communications for Location-Based Services Using Spare Extensions of Control Channels in Mobile Networks

Abstract

Location-based services (LBS) are services that are provided to the user according to their location. The components of an LBS needed to secure an end-to-end service successfully are: a mobile terminal; a positioning system; a communications network; and a service and data provider. In normal systems, the communication network used to transfer data and user requests to the data and service provider is the internet. Therefore, if the user has no internet access, the LBS cannot be completed and the mobile operator cannot exchange data with the user. In this paper, a recommended solution is proposed whereby control channels will used instead of data channels to send the user request to and from the service and data provider. The main advantages of this solution are that the connection between the user and the data and service provider is always available especially in case of emergency
