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.

A method of operating a communication system is disclosed. The method includes transmitting from a remote unit to a base station remote unit channel data. The remote unit channel is generated at the remote unit and includes data about a first portion of communication channels on which the call can be executed. The method also includes applying a channel selection method to the remote unit channel data and to base station channel data so as to select a communication channel from among the first portion of communication channels. The base station channel d...

1. A method of operating a communication system, comprising:transmitting, via an air link, remote unit channel data from a remote unit to a base station, the remote unit channel data being generated at the remote unit and including data about a first portion of communication channels on which a call can be executed;applying a channel selection method to the transmitted remote unit channel data so as to select a communication channel from among the first portion of communication channels;transmitting a channel identifier associated with the selected communication channel from the base station to the remote unit before executing the call on the selected communication channel;executing the call on the selected communication channel; andwaiting for the remote unit to contact the base station on the selected communication channel after transmitting the channel identifier. 2. The method of claim 1, wherein the remote unit channel data is transmitted to the base station over a control channel. 3. The method of claim 1, wherein the remote unit channel data includes data about the status of the first portion of the communication channels. 4. The method of claim 3, wherein the status of the first portion of the communication channels includes the strength of signals transmitted on the first portion of communication channels. 5. The method of claim 3, wherein the remote unit channel data includes data about the status of a second portion of the communication channels. 6. The method of claim 5, wherein the status of the first portion of the communication channels includes the strength of signals transmitted on the first portion of communication channels and the status of the second portion of the communication channels includes the strength of signals transmitted on the second portion of communication channels. 7. The method of claim 1, wherein the remote unit channel data includes preferred channel data. 8. The method of claim 1, wherein the channel identifier is transmitted over a control channel. 9. The method of claim 1, further comprising:transmitting a request for a second version of the remote unit channel data from the base station to the remote unit in response to execution of the channel selection method failing to result in selection of a communication channel; andtransmitting from the remote unit to the base station the second version of the remote unit channel data from the remote unit. 10. A method of operating a communication system, comprising:transmitting, via an air link, remote unit channel data from a remote unit to a base station, the remote unit channel data being generated at the remote unit and including data about a first portion of communication channels on which a call can be executed;applying a channel selection method to the transmitted remote unit channel data so as to select a communication channel from among the first portion of communication channels; andexecuting the call on the selected communication channel;wherein applying the channel selection method to the remote unit channel data includes applying the channel selection method to base station channel data, the base station channel data being generated at the base station and including data about a second portion of the communication channels. 11. A method of managing a call at a base station of a fixed wireless loop network, comprising:receiving from a remote unit, via an air link, remote unit channel data, the remote unit channel data being generated at the remote unit and including data about a first portion of communication channels on which the call can be executed;applying a channel selection method to the remote unit channel data so as to select a communication channel from among the first portion of communication channels;transmitting a channel identifier associated with the selected communication channel to the remote unit over a control channel before executing the call on the selected communication channel;executing the call on the selecte d communication channel; andwaiting for the remote unit to contact the base station on the selected communication channel after transmitting the channel identifier. 12. The method of claim 11, wherein the remote unit transmits the remote unit channel data to the base station over a control channel. 13. The method of claim 11, wherein the data about the first portion of the communication channels includes data about the status of the first portion of the communication channels and the remote unit channel data also includes data about the status of the second portion of a communication channels. 14. The method of claim 13, wherein the status of the first portion of the communication channels includes the strength of signals transmitted on the first portion of communication channels and the status of the second portion of the communication channels includes the strength of signals transmitted on the second portion of communication channels. 15. The method of claim 11, wherein the remote unit channel data includes preferred channel data. 16. The method of claim 11, further comprising:transmitting a request for a second version of the remote unit channel data from the base station to the remote unit in response to execution of the channel selection method failing to result in selection of a communication channel; andtransmitting from the remote unit to the base station the second version of the remote unit channel data from the remote unit. 17. The method of claim 16, wherein the second version of the remote unit channel data includes data for a different portion of communication channels than the first portion of communication channels. 18. A method of managing a call at a base station of a fixed wireless loop network, comprising:receiving from a remote unit, via an air link, remote unit channel data, the remote unit channel data being generated at the remote unit and including data about a first portion of communication channels on which the call can be executed;applying a channel selection method to the remote unit channel data so as to select a communication channel from among the first portion of communication channels; andexecuting the call on the selected communication channel,wherein applying the channel selection method to the remote unit channel data includes applying the channel selection method to base station channel data, the base station channel data being generated at the base station and including data about a second portion of the communication channels.
