Sub-frame allocation method, allocation device and network system

Abstract

The embodiment of the invention discloses a sub-frame allocation method, comprising the following steps of determining the predicted value of sent data within the sending time deviation of a data packThe embodiment of the invention discloses a sub-frame allocation method, comprising the following steps of determining the predicted value of sent data within the sending time deviation of a data packet and comparing the predicted value of the sent data with the data carrying capability of the sub-frame; if the data carrying capability of the sub-frame is more than or equal to the predicted valueet and comparing the predicted value of the sent data with the data carrying capability of the sub-frame; if the data carrying capability of the sub-frame is more than or equal to the predicted valueof the sent data, allocating a sub-frame to carry the sent data. The embodiment of the invention also provides an allocation device, which comprises an information unit, a comparison unit and a firstof the sent data, allocating a sub-frame to carry the sent data. The embodiment of the invention also provides an allocation device, which comprises an information unit, a comparison unit and a firstprocessing unit; wherein the information unit is used for determining the predicted value of the sent data within the sending time deviation of the data packet; the comparison unit is used for compariprocessing unit; wherein the information unit is used for determining the predicted value of the sent data within the sending time deviation of the data packet; the comparison unit is used for comparing the predicted value of the sent data with the data carrying capability of the sub-frame; and the first processing unit is used for allocating a sub-frame to carry the sent data when the comparisonng the predicted value of the sent data with the data carrying capability of the sub-frame; and the first processing unit is used for allocating a sub-frame to carry the sent data when the comparisonresult of the comparison unit is that the data carrying capability of the sub-frame is more than or equal to the predicted value of the sent data. The embodiment of the invention also provides a networesult of the comparison unit is that the data carrying capability of the sub-frame is more than or equal to the predicted value of the sent data. The embodiment of the invention also provides a network system. The technical proposal of the embodiment of the invention can improve the utilization ratio of the sub-frame and save network resources.rk system.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a subframe allocation method, allocation device and network system. Background technique [0002] MBMS (Multimedia Broadcast and Multicast Service, Multimedia Multicast Multicast) service is one of the important contents of 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) business development, mainly refers to the network side simultaneously sends the same multimedia data to Multiple recipients. SFN (Single Frequency Network, single frequency network) is an important application scenario of MBMS in LTE (Long Term Evolution, long-term evolution plan). In the SFN transmission mode, the SFA (Single Frequency Network area, single frequency network area) Multiple base stations simultaneously use the same physical resource to send the same data to the receiver, and the said same physical resource includes the same time resource and the ...
