Embodiment
Here will at length describe exemplary embodiment, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless separately there is expression, the same numbers in different accompanying drawings represents same or analogous key element.Execution mode described in following exemplary embodiment does not represent all execution modes consistent with the present invention.On the contrary, they are only and the example of apparatus and method as consistent in some aspects that described in detail in appended claims, of the present invention.
Fig. 1 is according to the flow chart of a kind of data transfer control method shown in an exemplary embodiment, and as shown in Figure 1, this data transfer control method, for terminal, comprises the following steps.
In step S101, whether the bandwidth of the first link group of monitoring terminal meets pre-conditioned.
For terminal, it can have multilink, for example: WiFi, GPRS (General Packet Radio Service, general packet radio service), EDGE (Enhanced Data Rate for GSM Evolution, enhanced data rates for gsm evolution technology), WCDMA (WidebandCodeDivision Multiple Access, Wideband Code Division Multiple Access (WCDMA)), HSPA (High-Speed Packet Access, high speed uplink packet access) and LTE (Long Term Evolution, Long Term Evolution) etc. technology form link.Fig. 2 is a kind of application scenarios of disclosure embodiment, and figure comprises: terminal 1, communication link 2, network 3 and server 4, and terminal 1 can be connected with network 3 by multilink, and carries out transfer of data, and server 4 is connected with network.
The first link group refers to the current combination of carrying out the link that transfer of data uses of terminal, and the first link group can comprise at least one in the multilink of this terminal.In disclosure embodiment, comprise that taking the first link group WiFi describes as example.As shown in Figure 3, the link that in figure, terminal 1 forms by WiFi technology and network 3 carry out data interaction.
Under normal circumstances, WiFi link can provide the data transmission bauds of tens Mbps, can meet the most transfer of data of user, but the situation that needs mass data to transmit for some, for example: user, in watching Online Video, need to download some data, now WiFi link cannot provide enough bandwidth to carry out transfer of data at short notice, this will terminal access speed decline, and causes Online Video to watch, and data is downloaded the problems such as length consuming time.
In disclosure embodiment, in order to address the above problem, the link using for current terminal, can preset some pre-conditioned, the upper limit with the bandwidth to the first link group is monitored, these are pre-conditioned can be the bandwidth availability ratio of link, can be also some parameters of link transmission data, for example: send the window size of data etc.
When the bandwidth of the first link group does not meet when pre-conditioned, show that the bandwidth of the first link group has reached the upper limit, if proceed transfer of data, and then the problem that there will be terminal access speed to decline.
When the bandwidth of described the first link group does not meet when pre-conditioned, in step S102, activate the second link group in the described multilink of described terminal.Otherwise process ends, continues to use the first link group to carry out transfer of data.
Described the second link group comprises at least one in described multilink, and the first link group is different with the second link group, is specially: any link in the first link group is all not identical with any link in described the second link group.
Aforementioned terminals has multilink, illustrates between terminal and network and has set up communication link, and just terminal is not used these communication links to carry out transfer of data.In this step, activate the second link group, the link of enabling in the second link group is carried out transfer of data by expression terminal.
In step S103, utilize the link in link and the second link group in described the first link group to transmit data simultaneously.
In the time that the first link group is WiFi, the second link group can be any one or more in GPRS, EDGE, WCDMA, HSPA and LTE, and as shown in Figure 4, in disclosure embodiment, the second link group describes as an example of GPRS example.Visible, when activating after the second link group, terminal is utilized between link in link and the second link group in the first link group and network simultaneously and is carried out transfer of data, the bandwidth between terminal and network is increased, and then can improve the message transmission rate between terminal and network.
This data transfer control method that disclosure embodiment provides, can monitor the bandwidth of the first link group of the terminal with multilink, and whether the bandwidth that judges the first link group is pre-conditioned, whether the bandwidth of the first link group is met the demands and judged, when bandwidth meets when pre-conditioned, it is the discontented sufficient requirement of this Time Bandwidth, the second link group in multiple links of activated terminals, and terminal utilizes the link in link and the second link group in the first link group to transmit data simultaneously.
For the link transmission data only using in the first link group, the method can be used the link in link and the second link group in the first link group to carry out transfer of data simultaneously, the bandwidth of terminal transmission data is increased, and the speed of transmission data also can correspondingly increase.Therefore, need the situation of mass data transmission for terminal, also can meet flexibly the requirement of terminal, avoid the problem that occurs that terminal access data are limited.
Fig. 5 is according to the flow chart of a kind of data transfer control method shown in another exemplary embodiment, and as shown in Figure 5, on the basis of method shown in Fig. 1, the method can also comprise the following steps.
In the time that the link in link and the second link group utilized in described the first link group transmits data simultaneously, in step S104, whether the bandwidth that continues to monitor the first link group of described terminal meets pre-conditioned.
This step can, referring to the step S101 in embodiment of the method shown in above-mentioned Fig. 1, not repeat them here.
When the bandwidth of described the first link group meets when pre-conditioned, in step S105, close the link in described the second link group.Otherwise, process ends, the state of activation of maintenance the second link group.
Referring in above-described embodiment about pre-conditioned description, visible, when the bandwidth of the first link group meets when pre-conditioned, show that the bandwidth of the first link group does not reach the upper limit, be not now restricted by the first link group transmission data, meet transfer of data requirement.
That is to say, now terminal there is no need to adopt the link in link and the second link group in the first link group to carry out transfer of data simultaneously simultaneously, if and now still keep link in link and the second link group in the first link group all in state of activation, owing to will maintaining the hardware device running that in two link group, link communicates, will certainly cause terminal to occur unnecessary kwh loss, reduce the cruising time of terminal.For this reason, in this step, by the link-down in the second link group.
In addition, when link in the second link group is closed, for the multiple links in the second link group, also can be with reference to the above-mentioned processing mode to the first link group and the second link group, using the bandwidth of a part of link in the second link group as foundation, by another part link-down in the second link group, so just can realize when the joint group in the second link group is while being multiple, can be in batches by the link-down in the second link group.
This data transfer control method that disclosure embodiment provides, when in the first link group, the bandwidth of link does not meet the demands, can be by activating the mode of link in the second link group, increase the bandwidth of terminal transmission data, and after the second link group activates, can also continue the bandwidth of link in the first link group to monitor, and in the time that the bandwidth of link in the first link group meets the demands, again by the link-down in the second link group, thereby can dynamically adjust according to the situation of terminal transmission data the bandwidth of terminal, to meet the requirement of terminal transmission data, avoid occurring because terminal data transmission quantity causes greatly the limited problem of visit data.
