Abstract
Disclosed is a mobile internet system, and more particularly, to a method and apparatus for supporting a multicast broadcast service (MBS) over WIMAX. The MBS supporting method of the present invention comprises assigning a first GRE key to a first MBS service flow for a first MS, and delivering MBS contents having the first MBS service flow through the use of first GRE key; and if a second MBS service flow for a second MS is the same as the first MBS service flow, delivering MBS contents having the second MBS service flow through the use of first GRE key pre-assigned to the first MBS service flow.
Claims24
An MBS supporting method comprising:
- assigning a first GRE key to a first MBS service flow for a first MS, and delivering MBS contents having the first MBS service flow through the use of first GRE key;
- and
- if a second MBS service flow for a second MS is the same as the first MBS service flow, delivering MBS contents having the second MBS service flow through the use of first GRE key pre-assigned to the first MBS service flow.
An MBS supporting method comprising:
- assigning a first GRE key to a first MBS service flow requesting a first QoS, and delivering MBS contents having the first MBS service flow through the use of first GRE key;
- and
- assigning the first GRE key to a second MBS service flow requesting the first QoS, and delivering MBS contents having the second MBS service flow through the use of first GRE key.
An MBS supporting method comprising:
- granting one MCID to an MBS program including multiple channels with the same Qos;
- assigning one GRE key to the MCID;
- and
- providing an MBS service through the use of GRE key.
An MBS supporting method comprising:
- assigning a first GRE key to a first MBS service flow for a first MS, and creating a GRE tunnel for the first MBS service flow through the use of first GRE key;
- if a second MBS service flow for a second MS, wherein the second MS is registered in the same MBS group as the first MS, is identical to the first MBS service flow, assigning the first GRE key to the first MBS service flow;
- and
- delivering MBS contents having the first MBS service flow, and MBS contents having the second MBS service flow through the use of GRE tunnel created through the first GRE key.
An MBS supporting apparatus comprising:
- a receiving means for receiving service flow information for MBS service flows;
- a GRE key assigning means for assigning a first GRE key to a first MBS service flow for a first MS registered in an MBS group through the use of service flow information;
- and, if a second MBS service flow for a second MS is identical to the first MBS service flow, assigning the first GRE key to the second MBS service flow;
- and
- delivering the first GRE key.
