Method and apparatus for communication in wireless communication system
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes receiving a first message including configuration information from a base station, setting an establishment cause based on whether the first message includes a first indicator indicating that a use of a value indicating a voice service as the establishment cause is requested, and transmitting a second message including the establishment cause for a radio resource control (RRC) connection request.
1. A method of a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a control message including a first indicator indicating that the terminal is requested to use a first value indicating a voice service as an establishment cause;
transmitting, to the base station, a radio resource control (RRC) connection request message for a service, wherein the RRC connection request message includes a first establishment cause which is set to a second value indicating a mobile originated data service;
receiving, from the base station, an RRC connection setup message; and
transmitting, to the base station, an RRC connection complete message, wherein the RRC connection complete message includes a second establishment cause which is set to the first value when the service corresponds to the voice service.
2. The method of claim 1 , wherein the control message comprises a system information block type 2.
3. The method of claim 1 , wherein the second establishment cause included in the RRC connection complete message is set to the first value indicating the voice service when the control message includes the first indicator and the terminal supports the first value indicating the voice service as the establishment cause.
4. A method of a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, a control message including a first indicator indicating that the terminal is requested to use a first value indicating a voice service as an establishment cause;
receiving, from the terminal, a radio resource control (RRC) connection request message for a service, wherein the RRC connection request message includes a first establishment cause which is set to a second value indicating a mobile originated data service;
transmitting, to the terminal, an RRC connection setup message; and
receiving, from the terminal, an RRC connection complete message, wherein the RRC connection complete message includes a second establishment cause which is set to the first value when the service corresponds to the voice service.
5. The method of claim 4 , wherein the control message comprises a system information block type 2.
6. A terminal in a wireless communication system, the terminal comprising:
a transceiver for transmitting and receiving signals; and
at least one processor configured to:
receive, from a base station, a control message including a first indicator indicating that the terminal is requested to use a first value indicating a voice service as an establishment cause,
transmit, to the base station, a radio resource control (RRC) connection request message for a service, wherein the RRC connection request message includes a first establishment cause which is set to a second value indicating a mobile originated data service,
receive, from the base station, an RRC connection setup message, and
transmit, to the base station, an RRC connection complete message, wherein the RRC connection complete message includes a second establishment cause which is set to the first value when the service corresponds to the voice service.
7. The terminal of claim 6 , wherein the control message comprises a system information block type 2.
8. The terminal of claim 6 , wherein the second establishment cause included in the RRC connection complete message is set to the first value indicating the voice service when the control message includes the first indicator and the terminal supports the first value indicating the voice service as the establishment cause.
9. A base station in a wireless communication system, the base station comprising:
a transceiver for transmitting and receiving signals; and
at least one processor configured to:
transmit, to a terminal, a control message including a first indicator indicating that the terminal is requested to use a first value indicating a voice service as an establishment cause,
receive, from the terminal, a radio resource control (RRC) connection request message for a service, wherein the RRC connection request message includes a first establishment cause which is set to a second value indicating a mobile originated data service,
transmit, to the terminal, an RRC connection setup message, and
receive, from the terminal, an RRC connection complete message, wherein the RRC connection complete message includes a second establishment cause which is set to the first value when the service corresponds to the voice service.
10. The base station of claim 9 , wherein the control message comprises a system information block type 2.
