Abstract:
1. A flexible connection control FAP (Femtocell Access Point) device of a small cell comprising an LTE (Long Term Evolution) link and providing VoLTE (Voice over LTE), PSVT (Packer Switch Video Telephony), and normal PS (Packet Service) services to mobile stations connected to the small cell, the flexible connection control FAP device, comprising: a controller; a UE (User Equipment) interface connected to the controller; a UL (Up Link) interface configured to connect an LTE FAP to an MME (Mobile Mobility Entity) through the LTE link; and an FAP access unit for an FAP service, wherein the controller comprises: an S1AP (S1 interface Application Protocol) message buffer configured to store an S1AP message of an E-RAB (E-UTRAN (Evolved Universal Terrestrial Radio Access Network) Radio Access Bearer) for setup, change, or release of a service; a system load data memory configured to store system load related information of the LTE FAP; and a mobile station service type memory including a VoLTE memory, a PSVT memory, and a normal PS memory configured to store information on mobile stations to which the LTE FAP is providing a service according to the type of the VoLTE, PSVT, and normal PS services, wherein the controller determines and controls connection of a mobile station by comparing a calculated system load and a maximum system load after calculating a system load when the mobile station is newly connected or transfers the type of service according to the type of the services that the mobile stations desire to use.
