Abstract
A method and apparatus providing broadcast content over a unicast channel. The method and apparatus may be configured to determine whether content received using a broadcast type format is to be transmitted using a unicast type format, and to map the content to a unicast reservation upon a determination that the content is to be transmitted using the unicast type format.
Claims29
A method for providing broadcast content over a unicast channel, the method comprising:
- determining that content received using a broadcast type format is to be transmitted using a unicast type format;
- mapping the content to a unicast reservation upon a determination that the content is to be transmitted using the unicast type format;
- and
- identifying, in the unicast type format and using at least one broadcast protocol identifier, the content received using the broadcast type format, wherein the broadcast protocol identifier corresponds to a framing format used in the broadcast type format.
1 more element
An apparatus, comprising:
- a content transmission selection module configured to:
- determine that content received using a broadcast type format is to be transmitted using a unicast type format;
- map the content to a unicast reservation upon a determination that the content is to be transmitted using the unicast type format;
- and
- identify, in the unicast type format and using at least one broadcast protocol identifier, the content received using the broadcast type format, wherein the broadcast protocol identifier corresponds to a framing format used in the broadcast type format.
2 more elements
An apparatus, comprising:
- a content transmission selection module configured to:
- determine whether content received using a broadcast type format is to be transmitted using a unicast type format;
- obtain a number of access terminals to receive the content;
- and
- if the number of access terminals to receive the content is less than a predetermined broadcast threshold, generate instructions for the content to be transmitted using the unicast type format;
- and
- upon a determination that the content is to be transmitted using the unicast type format, map the content to a unicast reservation, wherein the content received using the broadcast type format is identified in the unicast type format using at least one broadcast protocol identifier.
4 more elements
An apparatus, comprising:
- a content transmission selection module configured to:
- determine whether content received using a broadcast type format is to be transmitted using a unicast type format;
- determine that an access terminal receiving content using the broadcast type format is within a coverage threshold region, wherein the coverage threshold region is defined as predefined boundary region beyond which content may not be received using a broadcast type format;
- upon a determination that the access terminal in within the coverage threshold region, generate instructions for the content to be transmitted using the unicast type format;
- and
- upon a determination that the content is to be transmitted using the unicast type format, map the content to a unicast reservation, wherein the content received using the broadcast type format is identified in the unicast type format using at least one broadcast protocol identifier.
3 more elements
A method for receiving content by a wireless communications device (WCD), the method comprising:
- monitoring, by the WCD, content from a serving base station using a broadcast type format;
- detecting a target base station with a signal strength greater than a handover threshold value;
- determining whether the target base station is operable to communicate using the broadcast type format;
- upon a determination that the target base station is not operable to communicate using the broadcast type format, transmitting a request to the serving base station to transition content communication from using the broadcast type format to using a unicast type format;
- transitioning content communication from the broadcast type format to the unicast type format in response to a command received from the serving base station transmitted by the serving base station in response to the transmitted request;
- and
- processing a handover command from the serving base station to the target base station, wherein the handover includes maintaining content communication using the unicast type format.
4 more elements
A wireless communications device, comprising:
- a transceiver operable to:
- monitor content from a serving base station using a broadcast type format;
- a handover module, associated with a processor, and operable to:
- detect a target base station with a signal strength greater than a handover threshold value;
- and
- determine whether the target base station is operable to communicate using the broadcast type format;
- wherein the transceiver is further operable to transmit a request to the serving base station to transition content communication from using the broadcast type format to using a unicast type format upon a determination that the target base station is not operable to communicate using the broadcast type format;
- and
- wherein the handover module is further operable to:
- transition content communication from the broadcast type format to the unicast type format in response to a command received from the serving base station transmitted by the serving base station in response to the transmitted request;
- and
- process a handover command from the serving base station to the target base station, wherein the handover includes maintaining content communication using the unicast type format.
