Specifically, when terminal device #B has sent the relevant information of spatial cache #x (for example, caching to network equipment #B The size of space #x and initial position) when, network equipment #B can determine data #x based on the information that terminal device #B is reported Storage location in terminal device #B.

5. index of the data #x in multiple data that network equipment #B is sent to terminal device #B

Non-limiting as example, multiple data can be carried on different data packets respectively, also, in each data The index of the data carried in the data packet can be carried in packet, thus, network equipment #B can will distribute to each data Index is sent to terminal device #B.

To which before moment #c, terminal device #B can be received from network equipment #B including data #x Multiple data, and it is possible to multiple data of the caching including data #x in the buffer.

It should be noted that in the embodiment of the present application, multiple data of terminal device #B caching need to be committed to application (for example, above-mentioned moment #a) can be located at before moment #3 at the time of layer, can also be located at after moment #3, the application is not It is particularly limited to.

That is, being stored with multiple alternate datas in terminal device #B before moment #c.

Here, being somebody's turn to do " alternate data " can refer to that terminal device #B is received from network equipment #B and is buffered in caching sky Between in and be not yet committed to the data of application layer.

In the following, determining the movement progress needed when moment #c sends data #z to network equipment #B to terminal device #B It is described in detail.

Wherein, data #z is the data for needing to be committed to application layer by terminal device #B in moment #d, the moment #d After moment #c.Therefore, data #z needs to be buffered in the spatial cache of terminal device #B.

Due to being cached with alternate data in the spatial cache of terminal device #B, work as accordingly, it is possible to terminal device #B occur The case where preceding available cache memory space (that is, spatial cache of not stored data) is unable to satisfy the storage demand of data #z.

Therefore, in the embodiment of the present application, data #y can be determined from alternate data in S320, terminal device #B, In other words, determine the spatial cache of #y for storing data (that is, an example of the first spatial cache, hereinafter, in order to facilitate understanding And explanation, it is denoted as, spatial cache #y).Also, terminal device #B can delete stored in spatial cache #y data (that is, Data #y), thus, terminal device #B can in spatial cache #y some or all of storing data #z, in the following, to this Process is described in detail.

Non-limiting as example, terminal device can determine data #y or spatial cache #y based on following manner.

Mode 1

Terminal device #B can determine data #z institute according to the size (for example, bit number that data #z includes) of data #z The size of the spatial cache (hereinafter, in order to facilitate understanding and distinguish, referred to as target cache space) needed.

Terminal device #B can according to the size in terminal device #B current available cache memory space and the target cache space, It determines the size for needing the data (that is, data #y) deleted, in other words, determines the cushion space for needing to empty (that is, caching is empty Between #y) size.

Non-limiting as example, in the embodiment of the present application, spatial cache #y's is big determined by terminal device #B The sum of current size of available cache memory can be greater than or equal to the size in target cache space in small and terminal device #B.

Alternatively, in the embodiment of the present application, the size of spatial cache #y determined by terminal device #B can be greater than or Equal to the size in target cache space.

In addition, it is necessary to which explanation, data #y can be the arbitrary data in alternate data, in other words, the caching is empty Between #y can be any spatial cache in the occupied spatial cache of alternate data, as long as can make, spatial cache #y's is big It is small to meet above-mentioned condition.

Mode 2

Terminal device #B can determine data #y based on the priority of data #z.

Specifically, in the embodiment of the present application, terminal device #B can be by alternate data, and priority is lower than data The data of #z are determined as data #y.

Mode 3

At the time of terminal device #B can need to be committed to the application layer of terminal device #B based on each alternate data, number is determined According to #y.

For example, data at the time of terminal device #B can will need to be committed to application layer in alternate data relatively late, It is determined as data #y, non-limiting as example, data #y can be at the time of need to be committed to application layer in alternate data Data the latest.

It should be understood that aforesaid way 1, mode 2 and mode 3 can be used alone, the application can also to be used in combination not special It limits.

The number being stored in spatial cache #y can be sent to the network equipment in moment #c in S330, terminal device #B According to #z.

Instruction information #4 can be sent to network equipment #B (that is, the one of retransmission instruction information in S340, terminal device #B Example).

Wherein, instruction information #4 is used to indicate network equipment #B and retransmits data #y.

Optionally, instruction information #4 may include the information of the index of data #y.

Optionally, instruction information #4 may include the initial position of spatial cache #y and the information of size.

Optionally, instruction information #4 may include the information of the size of spatial cache #y.

Optionally, instruction information #4 may include the information of the size of data #y.

To which network equipment #B can be readily determined data #y based on instruction information #4.

It can be based on instruction information #4 in S350, network equipment #B, retransmit data #y to terminal device #B.
