Abstract
An apparatus and method for transmitting control information to provide an MBMS service in a mobile communication system. Upon receipt of a request for an MBMS service from at least one UE, a service ID is assigned to the MBMS service and a MAC message containing the service ID and control information of the MBMS service is transmitted to the at least one UE on a common channel.
Claims20
A method of transmitting multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service, comprising the steps of:
- assigning a service ID to the MBMS service upon receiving a request for a MBMS service from at least one user equipment (UE);
- and
- transmitting to the at least one UE a medium access control (MAC) message containing the service ID and control information of the MBMS service.
A method of transmitting multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service, comprising the steps of:
- assigning a service ID to the MBMS service upon receiving a request for a MBMS service from at least one user equipment (UE);
- and
- transmitting to the at least one UE a medium access control (MAC) message containing the service ID, a target channel type field (TCTF) identifying a channel to deliver control information of the MBMS service, and the MBMS control information.
An apparatus for transmitting multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service comprising:
- a controller for assigning a service ID to the MBMS service upon receiving a request for an MBMS service from at least one user equipment (UE);
- and
- a medium access control (MAC) message generator for generating a MAC message containing the service ID and control information of the MBMS service.
An apparatus for transmitting multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service, comprising:
- a controller for assigning a service ID to the MBMS service upon receiving a request for an MBMS service from at least one user equipment (UE), and deciding a target channel type field (TCTF) identifying a channel to deliver control information of the MBMS service;
- and
- a medium access control (MAC) message generator for generating a MAC message containing the service ID, the TCTF, and the MBMS control information.
A method of receiving multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service, comprising the steps of:
- receiving a service ID identifying the MBMS service after requesting an MBMS service;
- receiving on a common channel a medium access control (MAC) message containing a service ID and control information of an MBMS service;
- and
- performing a control operation according to the MBMS control information if the service ID included in the MAC message is identical to the service ID identifying the requested MBMS service.
A method of receiving multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service, comprising the steps of:
- receiving a service ID identifying the MBMS service after requesting an MBMS service;
- receiving on a common channel a medium access control (MAC) message containing a service ID, a target channel type field (TCTF), and control information of an MBMS service;
- and
- performing a control operation according to the MBMS control information if the service ID included in the MAC message is identical to the service ID identifying the requested MBMS service.
The method of claim l5, wherein the TCTF identifies a channel that delivers the MBMS control information.
An apparatus for receiving multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service, comprising:
- a receiver for receiving a service ID identifying the MBMS service, after requesting an MBMS service and receiving on a common channel a medium access control (MAC) message containing a service ID and control information of a MBMS service;
- and
- a service ID detector for performing a control operation according to the MBMS control information if the service ID included in the MAC message is identical to the service ID identifying the requested MBMS service.
An apparatus for receiving multimedia broadcast/multicast service (MBMS) control information in a mobile communication system supporting the MBMS service, comprising:
- a receiver for receiving a service ID identifying the MBMS service after requesting an MBMS service and receiving on a common channel a medium access control (MAC) message containing a service ID, control information of an MBMS service, and a target channel type field (TCTF) identifying a channel that delivers the MBMS control information;
- and
- a service ID detector for performing a control operation according to the MBMS control information if the service ID included in the MAC message is identical to the service ID identifying the requested MBMS service.
