Adding a Custom Service in Android System
This document describes how to add a custom service to the Android system. This example was implemented on Android 7.0, so code locations may vary on different systems.
1. Design the Interface
Create a new folder named addservice under the frameworks/base directory. Inside addservice, create the following structure:
Android.mkjava/android/mymodule/test(This path can be customized)
The java/android/mymodule/test directory will contain the Java interface files and corresponding AIDL files.

What is a Cell System?
A cell system consists of dividing the service area into cells, each containing a radio station that restricts its coverage area.
Elements of a Cellular System
- Mobile Stations (MS)
- Base Stations (BS)
- Mobile Switching Center (MSC)
- Public Switched Telephone Network (PSTN)
Understanding Hand-Over and Hand-Off
These are the necessary changes to keep communication channels uninterrupted when moving from one cell to another.

I. Introduction
Phase 1 of 5G is being standardized in 3GPP. 5G systems are expected to support various usage applications:
- Enhanced Mobile Broadband (eMBB)
- Massive Machine Type Communications (mMTC)
- Ultra Reliable Low Latency Communication (URLLC)
IMT-2020 (5G) is expected to provide the following key performance indicators (KPIs):
- > 10 Gbit/s peak data rate
- 100 Mbit/s user-experienced data rate
- 3x spectrum efficiency
- > 100 Mbps cell edge rates
