Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. An electronic device, comprising:
a communication module;
and a processor connected to the communication module,
wherein the processor is configured to:
detect a number for splitting one piece of content, and
allow a plurality of edge nodes to split and store at least some of packets split from the content based on the number,
wherein each of the edge nodes include a femto base station or a pico base station that is different from a user equipment (UE) and a macro base station (BS),
wherein the detecting of the number is performed based on a radius of an edge cell area in which coverage areas of the edge nodes overlap along with an average amount of storage of the edge nodes for the content,
wherein the edge nodes store the at least some of packets split from the content according to a maximum distance separable (MDS) coding scheme,
wherein the edge nodes distributed and deployed in the edge cell area directly transmit the stored packets simultaneously to the UE within the edge cell area in response to a-request from the UE by cooperating with each other without separate control of the macro base station (BS), wherein the UE receives the stored packets from the edge nodes and restores the content from the received packets, wherein the UE further receives a remainder of the packets from the BS if the edge nodes store some of the packets,
wherein the processor is configured to:
detect the number as, ⌊
  
   
    λπ
    ⁢
    
     r
     2

  ⌋, in response to when the average amount of storage is more than 0 and less than or equal to 2,
detect the number as, 6.25

   2, in response to when the average amount of storage exceeds 2,
maintain the detected number or re-detecting the number as a different value based on a signal to interference ratio (SIR) from the edge nodes to the UE,
wherein Mi indicates the average amount of storage, r indicates the radius, and λ, indicates average density of the edge nodes per unit area,
wherein the average amount of storage of the edge nodes for the content is based on a probability that the content will be stored over the number of the packets that the content is split into.
