Abstract:
According to the present invention, a carrier management method in which a mobile station that supports multiple carriers manages a primary carrier, wherein the method comprises the steps of receiving a primary carrier change command from a base station; and changing the primary carrier from a serving primary carrier to a target primary carrier.
Abstract:
Provided is a method of managing an MBS resource in a multicast and broadcast service. The MBS resource management method comprises: forming a plurality of domains, which include at least one first domain and second domain, by dividing a downlink resource within at least a time domain; allocating said at least one first domain to at least one MBS zone; and allocating said second domain to a unicast domain.
Abstract:
If area allocation information of a subband is changed, a terminal receives a new MBS setup message after a validity period of an MBS setup message has expired at a time when an SCD message including the changed area allocation information has been received. Then, the terminal applies the changed area allocation information at the start of a first MSI of the new MBS setup message.
Abstract:
When MBS information is updated, a base station transmits a first message which comprises: a service flow update identifier that identifies a method for expressing the current MBS identifier and flow identifier to be updated; information on the current MBS identifier and flow identifier expressed according to the method identified by the service flow update identifier; and new MBS information. A terminal transmits a second message to the base station in response to the first message.
Abstract:
A base station allocates paging groups to a mobile station. The base station transmits a first message which includes information on indexes of a plurality of carriers and a plurality of carriers to the mobile station, and transmits, to the mobile station, a second message which includes paging group information indicating whether each of the plurality of carriers support each of one or more paging groups. The base station selects a paging transmission carrier for the mobile station among one or more paging carriers corresponding to the paging groups allocated to the mobile station, and transmits a paging message through said paging transmission carrier.
Abstract:
Provided is a method in which a terminal receives multicast broadcast service in a wireless communication system. The method for receiving multicast broadcast service comprises the following steps: receiving a dynamic service addition (DSA) message from a base station via a primary carrier; switching the primary carrier into a secondary carrier on the basis of the DSA message; receiving an MBS configuration message (MBS-CFG) from the base station via the secondary carrier; and receiving the MBS data from the base station via the secondary carrier on the basis of the MBS configuration message.
Abstract:
Disclosed is a method for executing handover from a service base station to a target base station for providing service to a terminal in a wireless communication system. The method comprises the steps of: transmitting a handover request message to the service base station; and receiving a handover instruction message, constituting a response to the handover request message, from the service base station. Multi-carriers can be used effectively by pre-allocating multi-carriers immediately before handover, and activating some or all of the multi-carriers immediately after handover.
Abstract:
Disclosed is an operating method of a femto base station. The method comprises the steps of: transmitting information related to a first Low Duty Operation (LDO) pattern including length information of Available Interval (AI) as an active state of the femto base station and length information of Unavailable Interval (UAI) as an inactive state of the femto base station, to a terminal; and operating on the basis of the first LDO pattern formed by repeating a first LDO cycle that is a sequence of the AI and the UAI, wherein the information related to the first LDO pattern further includes a super frame offset that is information inducing a starting point of the first LDO cycle.
Abstract:
PURPOSE: An information obtaining method of a neighbor base station in a femto cell is provided to efficiently transmit a neighbor advertisement message to a terminal from a femto cell base station. CONSTITUTION: A terminal requests neighbor BS(Base Station) information through an NBR-REQ message(S310). The NBR-REQ message includes an RT(Request Base Station Type) field and a BSID field for BSID(Base Station Identifier). A femto BS(Base Station) analyzes the NBR-REQ message. The femto base station includes terminal request information in the NBR-ADV message(S320).
Abstract:
In a power saving operation management method in a mobile communication system, a base station receives a sleep mode entering request message from a mobile station desiring to enter the sleep mode, determines a sleep period type and a parameter by analyzing a combination of radio channels between the mobile station and the base station, and transmits a sleep mode entering response message including the sleep period type and the parameter.
