The application discloses an activation method of a secondary cell. The activation method includes the following steps: when system information change happens in a secondary cell (SCell) of UE and corresponding processing operations are completed, if the current service quantity of the UE is larger than a preset service quantity threshold and before the system information is changed, the SCell of the UE is at an activation state, a base station activates the SCell of the UE; and when the UE completes a switching process, if before the switching, an SCell at an activation state exists in the UE, the base station triggers the current SCell of the UE so as to carry out activation. Through adoption of the activation method of the secondary cell, a problem that user service continuity is affected when system information change of the SCell of the UE happens and switching happens can be effectively solved.
Description
Technical field
The present invention relates to mobile communication technology, particularly relate to a kind of Activiation method of auxiliary community.
Background technology
Carrier aggregation technology is to improve the direct method of message transmission rate.So-called carrier aggregation, refers to that user's data can be transmitted on multiple member carriers (Component Carrier, CC) simultaneously, has been equivalent to increase user's transmission bandwidth.In LTE Rel-10 agreement, the CC that user can use mostly simultaneously is most 5, and the maximum transmission bandwidth of unique user can reach 100MHz in theory like this, and this will greatly improve the peak rate of user data transmission.
CC has represented a up-link carrier or a descending carrier, and a up CC and a descending CC are associated and are just formed Liao Yige community (Cell) by certain corresponding relation, so carrier aggregation is also referred to as community polymerization (CellAggregation).Member carrier is divided into main member carrier (Primary CC, PCC) and auxiliary member carrier (Secondary CC, SCC) so that member carrier is managed, and specifies that each UE is up to a up PCC and a descending PCC.The effect of descending PCC comprise set up that RRC signaling connects, Non-Access Stratum (Non-Access Stratum, NAS) mobility and as the input of security parameters etc.; Up PCC is for sending the control information of physical layer.Descending PCC and up PCC are associated and have formed main plot (Primary Cell, PCell), and descending SCC and optional up SCC are associated and form Liao Fu community (Secondary Cell, SCell).
In Rel-10, because all carrier waves are all backward compatibility carrier waves, mean broadcast system information on each carrier wave.When subscriber equipment (UE) is transformed into CONNECTED state from IDLE state, resident carrier wave becomes PCell.The process of Rel-8/9 is continued to use in the SIM system information management of PCell, and SIM system information management two aspects when SIM system information management when management of SCell system information mainly increases from SCell and SCell system information change are considered.Change for SCell system information, the system information of upgrading by the transmission of RRC signaling, the method that first discharge this SCell and increase this SCell by the process of removal+addition realizes.
The activation of SCell and increase process are independently to carry out, and the object activating is mainly in order to tackle burst service.In LTE R10 agreement the SCell of specified configuration in the time newly increasing and handoff procedure be in deactivation status after completing.UE before changing for SCell system information or before switching has a large amount of transfer of data at SCell, when UE completes because of the associative operation of SCell changing system information or completes after handoff procedure, the state of the SCell of UE is in deactivation status, if the user of these class special circumstances activates SCell not in time, can have influence on continuity and the user oriented experience of business.
As can be seen here, in current system, switch or its SCell system information changes in the situation that, can exist because SCell affects the successional problem of customer service in deactivation status at UE.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of Activiation method of auxiliary community, when the SCell system information that the method can effectively solve UE changes and switches on the successional impact of customer service.
In order to achieve the above object, the technical scheme that the present invention proposes is:
An Activiation method for auxiliary community, comprising:
In the time that user equipment (UE) Yi Gefu community SCell generation systems information changes and complete corresponding processing operation; if the current traffic carrying capacity of described UE is greater than default traffic volume threshold; and before described changing system information, the described SCell of described UE is in state of activation, the described SCell of UE described in base station activation;
In the time that described UE completes handoff procedure, if described UE exists the SCell in state of activation before described switching, described base station triggers activates the current SCell of described UE.
In sum, the present invention proposes the Activiation method of Fu community, in the time that the SCell of UE system information changes and completes relevant treatment operations, if the traffic carrying capacity of this UE this SCell large and this UE before system information changes is in state of activation, this SCell of this UE that triggers the activation; In the time that UE completes handoff procedure, if this UE exists the SCell in state of activation before switching, SCell current this UE is activated.So, by time the SCell of UE being activated, make in the situation that switching or SCell system information changes, can not exist because SCell affects the successional problem of customer service in deactivation status.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, the present invention is described in further detail.
Core concept of the present invention is: in the situation that switching or SCell system information changes, in time whether the current SCell of UE is needed to activate and judge, and activate accordingly when needed, to avoid because SCell affects the successional problem of customer service in deactivation status.
The embodiment of the present invention one mainly comprises:
In the time that a SCell generation systems information of UE changes and complete corresponding processing operation, if the current traffic carrying capacity of described UE is greater than default traffic volume threshold, and before described changing system information, the described SCell of described UE is in state of activation, the described SCell of UE described in base station activation.
In the time that described UE completes handoff procedure, if described UE exists the SCell in state of activation before described switching, described base station triggers activates the current SCell of described UE.
In above-described embodiment, in the time that a SCell generation systems information of UE changes and complete corresponding processing operation, need to consider traffic carrying capacity and this SCell state before of UE simultaneously, if the traffic carrying capacity of UE is large and this SCell before in state of activation, be illustrated as the business demand needs that meet UE and activate this SCell, and for the little situation of traffic carrying capacity, even if this SCell is in state of activation before, this SCell is also little on the impact of its business continuance in deactivation status afterwards, like this, adopt said method can reduce as far as possible and activate the resource overhead that SCell produces, simultaneously, also can avoid for the large UE of traffic carrying capacity because its SCell is in deactivation status and exerting an influence to its business continuance.
In above-described embodiment, need to whether there is the SCell in state of activation according to UE before switching, determine whether to activate its current SCell.If before switching there is the SCell in state of activation in UE, be illustrated as the SCell that meets its business demand needs and activate some, now need triggering to activate SCell; If there is not the SCell in state of activation before, the business demand that does not need to activate SCell and also can meet UE is described, now do not need to trigger SCell is activated.So, with after avoiding switching to the blindness of SCell activate produced compared with large resource expense,, also can effectively reduce after switching because all SCell of UE are in deactivation status and the impact that its business continuance is produced meanwhile.
Particularly, in the time that the current SCell of described UE is activated, its quantity that activates SCell can be determined arbitrarily, at least one current described UE SCell can be activated; Also can determine the quantity that activates SCell according to the quantity of the SCell in state of activation of described UE before switching, N the SCell current by described UE activates, and described N is the described switching quantity of the SCell in state of activation of described UE before.
Particularly, described traffic volume threshold can be arranged according to actual needs by those skilled in the art.
Can find out from such scheme, adopt above-mentioned steps, the SCell that can activate needs in time in the time that SCell generation systems information changes and switches activates, to avoid the generation of above-mentioned situation on the successional impact of customer service.
In actual applications, in the time that user's traffic carrying capacity increases suddenly, also will increase the quantity demand of the SCell in state of activation, in the case, also need the SCell of excited users timely.Therefore, the continuity of customer service when further guaranteeing that traffic carrying capacity increases suddenly, preferably, the present invention can further include following step:
Base station, according to default measurement period, is added up the user satisfaction of described UE.
If the user satisfaction of the described UE counting on current is lower than default satisfaction threshold value, described base station judges the current SCell whether existing in deactivation status of described UE, if exist, select at least one SCell from the described SCell in deactivation status and activate.
Particularly, described measurement period and satisfaction threshold value, can be arranged according to actual needs by those skilled in the art.
Here, the same existing system of the definition of described user satisfaction, specific as follows:
For ensureing bit rate (GBR) business, to ensure that GBR is as target, the computing formula of its business satisfaction is
for user i is at the effective data rate of the MAC layer of the logic channel of t moment business j,
for smoothing factor, R (i, j, t) is the significant instant speed of user i at t moment business j logic channel MAC layer; R
gBRthe logic channel GBR of the business j that (i, j) is user i is embodied in the effective data rate of MAC layer.
For non-guarantee bit rate (non-GBR) business, consider delay character, its business satisfaction
t_delay
jfor PDB corresponding to QCI grade by business j converts RLC delay requirement end to end; Timer_threshold is the time delay thresholding that non-GBR business allows at rlc layer; Due to the up stand-by period that cannot obtain packet, judge criterion using the not scheduling time of such business as satisfaction, WT (i, j, t) be by the not scheduling time of the business j to subframe t user i, and the stand-by period of descending employing packet is considered its delay character, WT (i, j, t) be the stand-by period by the packet arriving at first of the business j to subframe t user i.
Preferably, the accuracy activating in order to improve SCell, described user satisfaction can be the average satisfaction of described UE all business in current measurement period.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
