Embodiment

[0075] Since multiple LTE modules of a multi-card multi-stream terminal in the prior art are relatively close to each other and have similar arrival quality, if it cannot be controlled, it is likely that multiple LTE modules are connected to the same cell, and multiple LTE modules cannot be fully utilized. The uplink performance of the multi-card multi-stream terminal, for example: the multi-card multi-stream terminal integrated with two LTE modules is almost inferior in the cell of the double-layer network. Although the uplink rate can be improved through the uplink MU-MIMO pairing, the improvement effect is about 10 %, very limited, far less than the improvement effect of two LTE modules connected to different cells. To solve this problem, as figure 1 As shown, the embodiment of the present invention provides a control method for accessing a cell, which is applied to a multi-card multi-stream terminal, including:

[0076] Step 10: Receive the network quality parameters of e...

example 1

[0105] When the multi-card multi-stream terminal includes two LTE modules,

[0106] If only one frequency point is measured, that is, only the currently accessed serving cell is detected, this judgment is skipped and the current access mode is not changed;

[0107] If two or more frequency points are detected, that is, not only the serving cell but also one or more neighboring cells are detected, the RSRP of the serving cell is RSRP1, and the maximum RSRP of the neighboring cells is RSRP2.

[0108] When both LTE modules are connected to the serving cell, the estimated total throughput value Tph=T(RSRP1)*(1+G(RSRP1));

[0109] When two LTE modules access the serving cell and the neighboring cell respectively, the expected total throughput value Tph=T(RSRP1)+T(RSRP2);

[0110] Among them, T(RSRP1) represents the throughput of accessing the serving cell, G(RSRP1) represents the throughput gain of accessing the serving cell, and T(RSRP2) represents the throughput of accessing the...

example 2

[0112] When the multi-card multi-stream terminal includes three LTE modules,

[0113] If only one frequency point is measured, that is, only the currently accessed serving cell is detected, this judgment is skipped and the current access method is not changed;

[0114] If two frequency points are measured, when two LTE modules access the serving cell, Tph=T(RSRP1)*(1+G(RSRP))+T(RSRP2), when two LTE modules access the adjacent cell , Tph=T(RSRP1)+T(RSRP2)*(1+G(RSRP2)); comparing the two Tph values ​​obtained by the above calculation, selecting the access cell combination corresponding to the maximum value as a decision strategy;

[0115] If three or more frequency points are measured, set the value of the adjacent cell that is less than RSRP2 to RSRP3. In this case, in addition to calculating the above two access cell combinations, it is also necessary to calculate the time when the three LTE cells access different cells. The expected total throughput value of Tph=T(RSRP1)+T(R...

Abstract

The invention discloses a control method of an access cell and an apparatus thereof, and a multi-card multithread terminal. The method comprises the following steps of receiving a network quality parameter of each cell reported by each LTE module, wherein each cell includes a service cell and an adjacent cell; according to the network quality parameter, calculating a throughput and a throughput gain of the LTE module accessing each cell respectively; according to the service cell and the adjacent cell, determining different access cell combinations which can be realized by the plurality of LTE modules, and according to the throughput and the throughput gain of the LTE module accessing each cell, calculating predicted total throughput values of the plurality of LTE modules under the different access cell combinations respectively; and selecting the access cell combination corresponding to a maximum value in the predicted total throughput values to be a decision strategy of the access cell. In the invention, through selecting the access cell combination with the maximal predicted total throughput value to be the decision strategy of the access cell, the access cell of each LTE module can be automatically adjusted according to an actual network condition and uplink performance of the multi-card multithread terminal is increased.

Description

technical field [0001] The present invention relates to the wireless field, in particular to a cell access control method, device and multi-card multi-stream terminal. Background technique [0002] With the construction of 4G network, 4G-based industrial applications are developing rapidly, such as high-definition video surveillance, instant capture, etc. Such video applications usually require high data transmission bandwidth, and the industry has launched multi-card multi-stream routers for this purpose. End products. [0003] The multi-card multi-stream terminal integrates more than two LTE modules or data cards, and performs data splitting and merging at the IP layer. Under a single-layer network, two LTE modules can perform uplink MU-MIMO pairing to improve uplink performance; under a multi-layer network , two LTE modules can access different cells respectively, similar to uplink carrier aggregation to improve uplink performance. However, in the prior art, the multi-c...
