Embodiment

To make the purpose, technical scheme and advantage of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application In accompanying drawing, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is Some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art The every other embodiment obtained under the premise of creative work is not made, belong to the scope of the application protection.

The technical scheme of the embodiment of the present invention, various wireless communication systems are can apply to, such as：Long Term Evolution（Long Term Evolution, LTE）System or advanced Long Term Evolution（Advanced Long Term Evolution, LTE-A） Other communication systems such as system or follow-up evolution.

Base station, can be the evolved base station in other communication systems such as LTE system, lte-a system or follow-up evolution （Evolved NodeB, eNB）Deng network element.

In addition, the terms "and/or", only a kind of incidence relation for describing affiliated partner, represents there may be Three kinds of relations, for example, A and/or B, can be represented：Individualism A, while A and B be present, these three situations of individualism B.Separately Outside, character "/" herein, it is a kind of relation of "or" to typically represent forward-backward correlation object.

In a wireless communication system, there is time delay in the air interface transmission between terminal and base station.Enter in terminal and base station After row synchronization, in order to ensure that the time point that the upward signal that terminal is sent requires in base station reaches base station, terminal needs to shift to an earlier date Data are sent, so as to offset the influence of the propagation delay time of air interface transmission.This time value shifted to an earlier date is exactly timing advance（Timing Advance, TA）Value.

Therefore, for some terminal, because different districts（Main plot or secondary cell）Uplink transmission path may not Together, cause the TA values of these cells may also be different.In general, terminal can perform random access procedure in different districts, To obtain the TA values of each cell.

For example, when base station needs to increase a secondary cell for terminal, the terminal needs to perform in the secondary cell to be connect at random Enter process, to obtain the TA values of the secondary cell, still, certain increase time delay can be brought by performing random access procedure.

Fig. 1 is the schematic flow sheet of the method for the increase secondary cell that the embodiment of the application one provides, as shown in Figure 1.

101st, the TA values of secondary cell to be increased are determined for terminal.

102nd, the first message for increasing the secondary cell is sent to the terminal, is included in the first message described The cell ID of secondary cell and the first configured information, first configured information are used to indicate the TA values.

It should be noted that 101 and 102 executive agent can be base station.

So far, because the first message that terminal is sent by base station obtains the TA values of the secondary cell, therefore, the end End can directly utilize the TA values, and data are sent by the secondary cell, and Stochastic accessing is performed so as to avoid the terminal Flow.

It should be noted that the concept for the increase secondary cell being related in the present invention, it can be understood as one cell of increase is made For secondary cell.

It should be noted that it is described auxiliary small to include increase in the first message for increasing the secondary cell The detailed description of the configuration information in area, the cell ID of the secondary cell and the configuration information of secondary cell may refer to prior art Related content, here is omitted.

Alternatively, in a possible implementation of the present embodiment, the first message can be Radio Resource control System（Radio Resource Control, RRC）Connect reconfiguration message.

Alternatively, in a possible implementation of the present embodiment, in 101, base station can specifically receive eventually When holding the A4 measurement events reported, the secondary cell for the terminal by the adjacent area increase indicated by the A4 measurement events is determined. Wherein, A4 measurement events represent that the neighboring area signal intensity is higher than a threshold value.Wherein, base station can configure the threshold value and be sent to Above-mentioned terminal, the threshold value can be Reference Signal Received Power（Reference Signal Received Power, RSRP）Or Reference Signal Received Quality（Reference Signal Received Quality, RSRQ）Related concrete numerical value.

Alternatively, in a possible implementation of the present embodiment, first configured information specifically can be used for The size of TA values described in explicit instruction.

Alternatively, in a possible implementation of the present embodiment, first configured information specifically can be used for TA values described in implicit instruction are 0.RACH is not carried for example, working as in above-mentioned first configured information（Random Access Channel, RACH）Configuration information or when not carrying specific TA values, it is that the implicit instruction TA values are 0.

Alternatively, in a possible implementation of the present embodiment, in 101, base station specifically can be according to described The coverage of secondary cell, determine the TA values of the secondary cell.For example, because the minimum step of the adjustment of TA values is 0.52 micro- Second, wireless signal probably propagates 156 meters or so within this time, therefore, be less than when the radius of the coverage of secondary cell or During equal to 156/2=78 meter, base station can then determine that the TA values of the secondary cell are 0.

Alternatively, in a possible implementation of the present embodiment, in 101, base station specifically can be according to described The position of terminal, determine the TA values of the secondary cell.

Alternatively, base station can be specifically calculated described in obtaining according to the position of the terminal and the position of the secondary cell The distance between secondary cell and the terminal, then, by the distance divided by rate of signal propagation（That is 300,000 thousand metre per second (m/s)s）, and Result is multiplied by 2 and obtains the TA values of the secondary cell.Wherein, the position of the secondary cell is the base station belonging to the secondary cell Position.

Alternatively, base station specifically can according to the position of the terminal, and the position of the terminal pre-set with it is auxiliary small The TA values in area, it is determined that the TA values with the secondary cell of the position correspondence of the terminal.For example, base station can prestore terminal Position and the corresponding relation of secondary cell TA values, and presented by tabular form.

Alternatively, in a possible implementation of the present embodiment, before 101, base station can further obtain The position of the terminal.

Specifically, base station can specifically send the second configured information to the terminal, and second configured information is used to refer to Show the position for sending the terminal, and receive the position for the terminal that the terminal is sent according to second configured information Put.Wherein, the terminal specifically can be according to global positioning system（Global Positioning System, GPS）Or see Survey reaching time-difference（Observed Time Difference Of Arrival, OTDOA）, obtain the position of the terminal.

For example, base station can specifically send the measurement task configuration information for including second configured information to the terminal （For example, the measurement task configuration information of A4 measurement events）, and receive the measurement report that the terminal is sent（For example, A4 is surveyed The measurement report of amount event）, the position of the terminal is included in the measurement report.

For another example base station can specifically send location request message to the terminal, and the terminal is received according to institute The position response message of location request message transmission is stated, the position of the terminal is included in the position response message.

Specifically, base station can specifically interact with the centre of location, obtain the position of the terminal.

Wherein, the centre of location is a kind of equipment for the position that terminal is obtained by some localization methods, for example, passing through GPS location method or observation reaching time-difference（Observed Time Difference Of Arrival, OTDOA）Positioning side The localization methods such as method, obtain the position of terminal.

Alternatively, in a possible implementation of the present embodiment, in 102, described the first of base station transmission disappears The 3rd configured information can also be further included in breath, the 3rd configured information is used to indicate whether to start TA timers, with So that the terminal starts according to the 3rd configured information or does not start the TA timers.

If for example, the 3rd configured information instruction starts TA timers, then, when TA timer expiries, represent The TA values obtained before（TA values indicated by i.e. described first configured information）It is insincere, because the change in location of terminal may The TA values are caused to change.After TA timer expiries, terminal can not then send upstream data, and rear extended meeting passes through other method weight Newly obtain new TA values.For example, terminal can perform random access procedure in the secondary cell, determined using obtaining base station as the terminal The secondary cell new TA values.

So, by the 3rd configured information indicate start TA timers, can secondary cell coverage it is larger When, with the TA values for the secondary cell that the movement of terminal, the base station that can upgrade in time determine for terminal.

If for another example the 3rd configured information instruction does not start TA timers, then, then it is considered that TA timers It is always not time out, that is to say, that the TA values obtained before are credible always.

So, by the 3rd configured information instruction do not start TA timers, can secondary cell coverage compared with Hour, the TA values of the secondary cell determined without the mobile continuous renewal base station with terminal for terminal, because the shifting with terminal It is dynamic, the TA values will not be caused to change, so as to save the empty overhead for reacquiring TA values, for example, saving by TA orders （TA Command）Reacquire the empty overhead of TA values.

It should be noted that the 3rd configured information and first configured information can be same configured information, Or can also be different configured informations, the present embodiment is to this without limiting.

Alternatively, in a possible implementation of the present embodiment, have belonging to a kind of possible scene i.e. main plot Base station and secondary cell belonging to base station differ, cell-Radio Network Temporary Identifier corresponding to the secondary cell（Cell Radio Network Temporary Identifier, C-RNTI）Different from C-RNTI corresponding to main plot.Therefore, 102 In, C-RNTI corresponding to the secondary cell can also be further included in the first message that base station is sent, it is described to cause C-RNTI of the terminal using the C-RNTI as the secondary cell, so as to improve the accuracy of secondary cell configuration.

Optionally, in a possible implementation of the present embodiment, relative to the larger macrocell of coverage Speech, the secondary cell can be the less cell of coverage, such as Microcell（Pico cells）Or picocell（Femto is small Area）.Wherein, the base station belonging to the picocell can be Home eNodeB.When terminal in Microcell or picocell etc. it is fast When speed is mobile, by shortening the turn-on time of terminal, for the coverage of Microcell or picocell etc., Ke Yiyou Effect improves communication utilization rate of the terminal in Microcell or picocell etc..

In the present embodiment, by the TA values that secondary cell to be increased is determined for terminal, enabling sent to the terminal For increasing the first message of the secondary cell, cell ID and the first instruction of the secondary cell are included in the first message Information, first configured information is used to indicate the TA values, by the first message that terminal is sent by base station obtains institute The TA values of secondary cell are stated, therefore, the terminal can directly utilize the TA values, and data are sent by the secondary cell, so as to Avoid the terminal and perform random access procedure, and then can avoid increasing time delay caused by execution random access procedure.

202nd, using the TA values, data are sent by the secondary cell.

It should be noted that 101 and 102 executive agent can be terminal.

It should be noted that the secondary cell can also be included in the first message for increasing the secondary cell The detailed description of relevant configuration information, the cell ID of the secondary cell and the configuration information of secondary cell may refer to prior art Related content, here is omitted.

Alternatively, in a possible implementation of the present embodiment, what base station can specifically report in receiving terminal During A4 measurement events, the secondary cell for the terminal by the adjacent area increase indicated by the A4 measurement events is determined.Wherein, A4 is surveyed Amount representations of events neighboring area signal intensity is higher than a threshold value.Wherein, base station can configure the threshold value and be sent to above-mentioned terminal, should Threshold value can be Reference Signal Received Power（Reference Signal Received Power, RSRP）Or reference signal connects Receive quality（Reference Signal Received Quality, RSRQ）Related concrete numerical value.

Alternatively, in a possible implementation of the present embodiment, first configured information specifically can be used for TA values described in implicit instruction are 0.RACH configuration informations are not carried in above-mentioned first configured information or are not carried specific for example, working as It is that the implicit instruction TA values are 0 during TA values.

Wherein, base station determines that the method for the TA values of the secondary cell may refer to the phase in embodiment corresponding to Fig. 1 inside the Pass Hold, here is omitted.
