Abstract
[Object] To provide a mechanism that enables a terminal device to receive streaming data stably and that can be more easily implemented. [Solution] Provided is a communication control device including: a control unit configured to cause each of segments included in streaming data to be delivered to one or more terminal devices in an area including a plurality of overlapping cells to be delivered from a first access point of a first cell in a first time slot and to be delivered from a second access point of a second cell overlapping the first cell in a second time slot different from the first time slot.
Claims19
A communication control device, comprising:
- one or more processors configured to:
- deliver each of segments included in streaming data to at least one terminal device in an area including a plurality of overlapping cells from a first access point of a first cell in a first time slot and from a second access point of a second cell that overlaps the first cell in a second time slot different from the first time slot,
- wherein each of the first access point and the second access point includes an Internet Protocol (IP) address filtering function;
- allocate a same multicast address to packets to transfer segments to access points that deliver a same segment in a same time slot;
- and
- allocate different multicast addresses to packets to transfer segments to access points that deliver a same segment in different time slots.
A communication control method, comprising:
- delivering each of segments included in streaming data to at least one terminal device in an area including a plurality of overlapping cells from a first access point of a first cell in a first time slot;
- delivering each of the segments from a second access point of a second cell overlapping the first cell in a second time slot different from the first time slot,
- wherein each of the first access point and the second access point includes an Internet Protocol (IP) address filtering function;
- allocating a same multicast address to packets to transfer segments to access points that deliver a same segment in a same time slot;
- and
- allocating different multicast addresses to packets to transfer segments to access points that deliver a same segment in different time slots.
A non-transitory computer-readable medium having stored thereon computer-readable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:
- delivering each of segments included in streaming data to at least one terminal device in an area including a plurality of overlapping cells from a first access point of a first cell in a first time slot and from a second access point of a second cell overlapping the first cell in a second time slot different from the first time slot,
- wherein each of the first access point and the second access point includes an Internet Protocol (IP) address filtering function;
- allocating a same multicast address to packets to transfer segments to access points that deliver a same segment in a same time slot;
- and
- allocating different multicast addresses to packets to transfer segments to access points that deliver a same segment in different time slots.
A terminal device, comprising:
- one or more processors configured to:
- receive each of segments included in streaming data from an access point in a first time slot in a time window including the first time slot and a second time slot;
- and
- cause a wireless communication unit of the terminal device to sleep at least partially in the second time slot based on a lack of reception of the segment from the access point,
- wherein the access point includes an Internet Protocol (IP) address filtering function,
- wherein a same multicast address is allocated to packets to transfer segments to access points that deliver a same segment in a same time slot, and
- wherein different multicast addresses are allocated to packets to transfer segments to access points that deliver a same segment in different time slots.
A data receiving method, comprising:
- receiving, in a terminal device, each of segments included in streaming data from an access point in a first time slot in a time window including the first time slot and a second time slot;
- and
- causing a wireless communication unit of the terminal device to sleep at least partially in the second time slot based on a lack of reception of the segment,
- wherein the access point includes an Internet Protocol (IP) address filtering function,
- wherein a same multicast address is allocated to packets to transfer segments to access points that deliver a same segment in a same time slot, and
- wherein different multicast addresses are allocated to packets to transfer segments to access points that deliver a same segment in different time slots.
A non-transitory computer-readable medium having stored thereon computer-readable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:
- receiving each of segments included in streaming data from an access point in a first time slot in a time window including the first time slot and a second time slot;
- and
- causing a wireless communication unit of a terminal device to sleep at least partially in the second time slot based on a lack of reception of the segment from the access point,
- wherein the access point includes an Internet Protocol (IP) address filtering function,
- wherein a same multicast address is allocated to packets to transfer segments to a first set of access points that deliver a same segment in a same time slot, and
- wherein different multicast addresses are allocated to packets to transfer segments to a second set of access points that deliver a same segment in different time slots.
A method for communicating, comprising:
- providing a wireless communication service to a terminal device in a first cell;
- delivering each of segments included in streaming data to the terminal device;
- and
- delivering each segment to the terminal device in a first time slot different from a second time slot in which each segment is delivered in a second cell that overlaps the first cell,
- wherein an access point includes an Internet Protocol (IP) address filtering function,
- wherein a same multicast address is allocated to packets to transfer segments to access points that deliver a same segment in a same time slot, and
- wherein different multicast addresses are allocated to packets to transfer segments to access points that deliver a same segment in different time slots.
