Abstract

Machine Type Communication (MTC) devices which have been applied extensively generate a small amount of data exchanged periodically However legacy transmission method used in 3GPP is not suitable for MTC device to perform small data transmission The reason is these devices will have to perform random access procedures to establish the Radio Resource Control (RRC) connection This scenario will increase network overhead and power consumption of MTC device Non-Access Stratum (NAS) method proposed from 3GPP TR23 887 document can improve network overhead Small data can be added into NAS packet and NAS packet supports the encrypted function for protecting data Hence the transmission procedures which included the establishment of the radio bearers and security mode are redundant Nevertheless this document does not show sufficient simulation statistics which prove this method is efficient The objective of this thesis is to devise an analytical model used to explore if NAS method can be applied to small data transmission Numerical result shows that NAS method can extend the lifetime of device without causing the increment of access delay when infrequently small data being produced
