METHOD FOR PROVIDING CONNECTION TYPE INFORMATION AND METHOD FOR CONTROLLING RADIO RESOURCE OF HOME (E)NODEB

Abstract

A method for providing connection type information in a Mobile Management Entity (MME) and a method for controlling radio resources in a Home (e)NodeB system are discussed. The method for providing connection type information according to an embodiment includes receiving an Attach Request message from a Home (e)NodeB. The Attach Request message includes a Closed Subscriber Group (CSG) ID and an access mode of the Home (e)NodeB when the Home (e)NodeB is a hybrid cell. The Attach Request message includes a CSG ID but does not include an access mode of the Home (e)NodeB when the Home (e)NodeB is not a hybrid cell. The method for providing connection type information further includes determining whether the UE is a CSG member or a non CSG member if the Home (e)NodeB is a hybrid cell; and transmitting a connection accept message when the Home (e)NodeB is the hybrid cell.

Claim

1. A method for providing connection type information in a Mobile Management Entity (MME), the method comprising:
receiving an Attach Request message from a Home (e)NodeB,
wherein the Attach Request message includes a Closed Subscriber Group (CSG) ID and an access mode of the Home (e)NodeB, when the Home (e)NodeB is a hybrid cell, and
wherein the Attach Request message includes a CSG ID but does not include an access mode of the Home (e)NodeB, when the Home (e)NodeB is not a hybrid cell;
transmitting an update location request message to a HSS (Home Subscriber Server);
receiving, from the HSS, an update location acknowledgement message including the UE's subscriber information;
determining, by the MME, whether the UE is a CSG member or a non CSG member based on the access mode information and the UE's subscriber information, if the Home (e)NodeB is a hybrid cell; and
transmitting, by the MME to the Home (e)NodeB, a connection accept message including an information indicating whether the UE is the CSG member or the Non-CSG member when the Home (e)NodeB is the hybrid cell.
2. The method of claim 1, wherein the radio resource control comprises at least one of a rate control and a diversion of establishment connection.
3. A method for controlling radio resources in a Home (e)NodeB system, the method comprising:
receiving, by the Home (e)NodeB, an attach request from a User Equipment (UE);
transmitting, by the Home (e)NodeB to a Mobile Management Entity (MME), an Attach Request message, in response to the received Attach Request message,
wherein the Attach Request message including a CSG ID and access mode of the Home (e)NodeB, when the Home (e)NodeB is a hybrid cell, and
wherein the Attach Request message including a CSG ID but does not include an access mode of the Home (e)NodeB, when the Home (e)NodeB is not a hybrid cell;
receiving, by the Home (e)NodeB from the MME, a connection accept message including an information indicating whether the UE is the CSG member or the Non-CSG member when the Home (e)NodeB is the hybrid cell;
establishing, by the Home (e)NodeB, a connection with the UE in response to the received connection accept message; and
performing, by the Home (e)NodeB, a radio resource control function with respect to the established connection based on the received indication.
4. The method of claim 3, wherein the radio resource control comprises at least one of a rate control and a diversion of establishment connection.
5. The method of claim 3, wherein the radio resource control function further comprises:
if the UE is the CSG member and the Home (e)NodeB having a deficient radio resource, performing, by the Home (e)NodeB, a handover of the UE to other CSG cell.
6. The method of claim 3, wherein the radio resource control function further comprises:
if the UE is the CSG member and the Home (e)NodeB having a deficient radio resource, releasing, by the Home (e)NodeB, a handover of the UE to a non-CSG cell.
7. The method of claim 3, wherein the MME is a new MME changed from an old MME due to a movement of the UE.
