Abstract
The invention relates to a method for sending control data in a hybrid wireless/broadcast network system, said network system comprising a broadcast network dedicated to transmission of broadcast services through at least a broadcast cell and a wireless network dedicated to transmission of at least a service through a plurality of cells, a cover area of the broadcast cell covering, at least partially, a cover area of a first cell and a cover area of a second cell among the plurality of cells, said method comprising: when control data related to a service of the first cell is identical to control data related to a service of a second cell, sending the control data through the broadcast cell.
Claims20
A method for transmitting control data in a hybrid broadband/broadcast network system, said network system comprising a broadcast network dedicated to transmission of broadcast services through at least one broadcast cell and a wireless cellular network dedicated to transmission of at least a service through a plurality of cells, a coverage area of the at least one broadcast cell covering, at least partially, a coverage area of a first cell and a coverage area of a second cell among the plurality of cells, said method comprising:
- determining whether common control data is transmitted using the wireless cellular network, wherein common control data comprises control data related to a service that is provided by or through the first cell and by or through the second cell;
- and
- based on determining that common control data is transmitted using the wireless cellular network, offloading the common control data from the wireless cellular network to the broadcast network, including transmitting, using the broadcast network, the common control data through the at least one broadcast cell, while user data and user specific control data are transmitted using the wireless cellular network, respectively through the first cell and the second cell.
A non-transitory computer-readable medium comprising instructions stored thereon, which when executed by a processor implement a method for transmitting control data in a hybrid broadband/broadcast network system, said network system comprising a broadcast network dedicated to transmission of broadcast services through at least one broadcast cell and a wireless cellular network dedicated to transmission of at least a service through a plurality of cells, a coverage area of the at least one broadcast cell covering, at least partially, a coverage area of a first cell and a coverage area of a second cell among the plurality of cells, said method comprising:
- determining whether common control data is transmitted using the wireless cellular network, wherein common control data comprises control data related to a service that is provided by or through the first cell and by or through the second cell;
- and
- based on determining that common control data is transmitted using the wireless cellular network, offloading the common control data from the wireless cellular network to the broadcast network, including transmitting, using the broadcast network, the control data through the at least one broadcast cell, while user data and user specific control data are transmitted using the wireless cellular network, respectively through the first cell and the second cell.
A hybrid wireless/broadcast network system, said network system comprising a broadcast network dedicated to transmission of broadcast services through at least one broadcast cell and a wireless cellular network dedicated to transmission of at least an unicast service through a plurality of cells, a coverage area of the at least one broadcast cell covering, at least partially, a coverage area of a first cell and a coverage area of a second cell among the plurality of cells, the system comprising at least one network entity comprising:
- a wireless/broadcast network interface;
- and
- a processor configured for implementing a method for transmitting control data, comprising:
- determining whether common control data is transmitted using the wireless cellular network, wherein common control data comprises control data related to a service that is provided by or through the first cell and by or through the second cell;
- and
- based on determining that common control data is transmitted using the wireless cellular network, offloading the common control data from the wireless cellular network to the broadcast network, including transmitting, using the broadcast network, the common control data through the at least one broadcast cell, while user data and user specific control data are transmitted using the wireless cellular network, respectively through the first cell and the second cell.
