US 8,265,626 B2 · Method of setting up connection in a communication system, radio network controller, and communication system

Abstract

A method of setting up a connection in a communication system is provided, wherein the communication system includes a user equipment (UE). The present method includes following steps. When a first radio resource control (RRC) connection request message is received from the UE, whether the first RRC connection request message has been received before is determined. If the first RRC connection request message has been received, a first RRC connection setup message is sent back to the UE. If the first RRC connection request message has not been received, whether there is an accessible Femto access point (FAP) near the UE is further determined. If there is the accessible FAP near the UE, a first RRC connection reject message is sent back to the UE. If there is no accessible FAP near the UE, the first RRC connection setup message is sent back to the UE.

Dependent claims

A method of setting up a connection in a communication system, the communication system comprising a user equipment (UE) and a network controller (RNC), the method being performed by the RNC and comprising:

receiving a first radio resource control (RRC) connection request message from the UE;
determining whether the first RRC connection request message has been received before, wherein
if the first RRC connection request message has been received before, a first RRC connection setup message is sent back to the UE, and if the first RRC connection request message has not been received before, whether there is an accessible Femto access point (FAP) near the UE is further determined;
and
if there is the accessible FAP near the UE, a first RRC connection reject message is sent back to the UE to guide the UE to the accessible FAP, and if there is no accessible FAP near the UE, the first RRC connection setup message is sent back to the UE.

2 more elements

A communication system, comprising a UE, a RNC, and a FAP, wherein the RNC comprises:

a transceiver unit, for receiving a first RRC connection request message or a first RRC connection setup complete message from the UE and sending back a first RRC connection setup message or a first RRC connection reject message to the UE;
a processing unit, coupled to the transceiver unit, for determining whether the transceiver unit has received the first RRC connection request message from the UE before, and if the transceiver unit has not received the first RRC connection request message before, searching a database to determine whether there is the accessible FAP near the UE, so as to determine whether the transceiver unit needs to send the first RRC connection reject message to the UE to guide the UE to the accessible FAP and allow the UE to set up a connection with the FAP, wherein the first RRC connection reject message carries an information of the FAP;
and
a database, coupled to the processing unit, for storing a context of the FAP.
