연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

The present invention relates to communicating between a network and user equipment in a wireless communication system. The invention includes receiving an indicator on a first transmission frequency having no associated uplink service. The indicator indicates at least one transmission frequency different from the first transmission frequency and having no associated uplink service. Moreover, the indicator indicates whether the availability of a service on the at least one transmission frequency is provided on the first transmission frequency.

1. A method for communicating between a network and user equipment (UE), the method comprising: receiving, from a multicast broadcast single frequency network (MBSFN) by the UE handed over from a current cell to a neighbor cell, a neighbor list that specifies cells or frequencies to which a dual receiver UE is permitted to listen, the neighbor list including an indicator on a first transmission frequency having no associated uplink service, wherein the neighbor list identifies particular transmission frequencies of neighbor cells as being available, wherein the neighbor cells are part of a geographic area different from a geographic area of a cell for the first transmission frequency,wherein the indicator transmitted on the first transmission frequency indicates the availability of at least one service provided on at least one neighboring transmission frequency, andwherein the at least one service is received from the MBSFN that has at least one single frequency network (SFN) area having a set of cells that all transmit the same frequency and the same content such that the set of cells appear to be a single cell from the perspective of the UE; andreceiving, by the UE, the at least one neighboring transmission frequency when the indicator indicates that the availability of the at least one service is not provided on the first transmission frequency, that the at least one neighboring transmission frequency provides information regarding all available services on all frequencies, or that no frequency provides information regarding all available services on all frequencies. 2. The method of claim 1, further comprising receiving the at least one neighboring transmission frequency in addition to the first transmission frequency. 3. The method of claim 2, wherein the at least one neighboring transmission frequency is received periodically. 4. The method of claim 1, further comprising receiving the at least one neighboring transmission frequency in place of the first transmission frequency. 5. The method of claim 4, wherein the at least one neighboring transmission frequency is received periodically. 6. The method of claim 1, wherein a priority scheme is used to indicate whether the availability of the at least one service on the at least one neighboring transmission frequency is provided on the first transmission frequency. 7. The method of claim 1, wherein a frequency flag scheme is used to indicate whether the at least one neighboring transmission frequency provides information on all available services on all frequencies. 8. A method for communicating between a network and user equipment (UE), the method comprising: transmitting, from a multicast broadcast single frequency network (MBSFN) to the UE handed over from a current cell to a neighbor cell, a neighbor list that specifies cells or frequencies to which a dual receiver UE is permitted to listen, the neighbor list including an indicator on a first transmission frequency having no associated uplink service, wherein the neighbor list identifies particular transmission frequencies of neighbor cells as being available, wherein the neighbor cells are part of a geographic area different from a geographic area of a cell for the first transmission frequency,wherein the indicator transmitted on the first transmission frequency indicates the availability of at least one service provided on at least one neighboring transmission frequency, andwherein the at least one service is transmitted from the MBSFN that has at least one single frequency network (SFN) area having a set of cells that all transmit the same frequency and the same content such that the set of cells appear to be a single cell from the perspective of the UE; andtransmitting, to the UE, the at least one neighboring transmission frequency when the indicator indicates that the availability of the at least one service is not provided on the first transmission frequency, that the at least one neighboring transmission frequency provides information regarding all available services on all frequencies, or that no frequency provides information regarding all available services on all frequencies. 9. The method of claim 8, wherein a frequency flag scheme is used to indicate whether the at least one neighboring transmission frequency provides information on all available services on all frequencies. 10. The method of claim 8, wherein a priority scheme is used to indicate whether the availability of a service on the at least one neighboring transmission frequency is provided on the first transmission frequency. 11. A user equipment (UE) for communicating with a multicast broadcast single frequency network (MBSFN), the UE comprising: at least one antenna associated with a radio frequency module; anda processor for controlling the UE, wherein the processor is configured to: receive, from a multicast broadcast single frequency network (MBSFN) the UE handed over from a current cell to a neighbor cell, a neighbor list that specifies cells or frequencies to which a dual receiver UE is permitted to listen, the neighbor list including an indicator on a first transmission frequency having no associated uplink service, wherein the neighbor list identifies particular transmission frequencies of neighbor cells as being available, wherein the neighbor cells are part of a geographic area different from a geographic area of a cell for the first transmission frequency,wherein the indicator transmitted on the first transmission frequency indicates the availability of at least one service provided on at least one neighboring transmission frequency, andwherein the at least one service is received from the MBSFN that has at least one single frequency network (SFN) area having a set of cells that all transmit the same frequency and the same content such that the set of cells appear to be a single cell from the perspective of the UE; andreceive the at least one neighboring transmission frequency when the indicator indicates that the availability of the at least one service is not provided on the first transmission frequency, that the at least one neighboring transmission frequency provides information regarding all available services on all frequencies, or that no frequency provides information regarding all available services on all frequencies.
