Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method, an apparatus, and a base station for activating and deactivating an auxiliary carrier.
Background
After the 3GPP protocol adds the downlink Dual carrier, in order to further increase the Uplink service rate and increase the balance between the Uplink carrier and the downlink carrier, the 3GPP protocol introduces an Uplink Dual carrier technology, Dual-carrier High Speed Uplink Packet Access (abbreviated DC-HSUPA). The DC-HSUPA allows a user to use two adjacent frequency points of the same frequency band when sending uplink data, can effectively improve the uplink rate of the user (the maximum rate is close to two times), and can enable the user positioned at the center and the edge of a cell to continuously sense the improvement of the uplink network speed.
According to the result of the DC-HSUPA network access test, if the secondary carrier cell is not overloaded, the transmission delay of the dual-carrier DC user is significantly better than that of the single-carrier SC user for burst service, i.e., burst service. In an interference test performed under the condition that the internet surfing rate of a DC user is approximately doubled relative to the internet surfing rate of an SC user, for burst service, the DC-HSUPA service can bring about 80% of rate gain. Therefore, for a large number of burst services (including wechat, microblog and the like) on the commercial network, the DC-HSUPA service is also required to be used, so that the user can enjoy the gain brought by the DC-HSUPA.
At present, for a method for implementing activation and deactivation of an auxiliary carrier of a DC-HSUPA service, it needs to consider that a User Equipment buffer (abbreviated UE buffer) has sufficient data to activate the auxiliary carrier, and the auxiliary carrier is not activated when the data amount is insufficient, so that the auxiliary carrier may not be activated for a large number of burst services (including WeChat, microblog, and the like) on a commercial network. In addition, the method of activating and deactivating the secondary carrier used in the prior art is to control at the level of a Radio Network Controller (RNC), and a corresponding measurement report or parameter needs to be reported to the RNC by a user equipment (ue) or a base station. Therefore, a method, an apparatus and a base station for activating and deactivating a secondary carrier are needed to solve the above technical problems in the prior art.

Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.
The method for activating and deactivating the secondary carrier provided by the invention can enjoy the gain brought by the DC-HSUPA in the burst type service which is common on the commercial network, and the method for activating and deactivating the secondary carrier and each step thereof are described in detail below.
First embodiment
As shown in fig. 1, the method for activating a secondary carrier according to this embodiment includes: step S10: checking power headroom UPH of SC-HSUPA UE on primary carrierpriWhether or not to be greater than or equal to threshold value UPH of power headroom of activated secondary carrierAct-thr. If UPHpriLess than UPHAct-thrThen, the process is ended directly. If the case of step S20 occurs: if UPHpriUPH or higherAct-thrFurther judging the Cell load of the auxiliary carrier of the UE of SC-HSUPAsecWhether the Cell Load is less than or equal to a threshold value Cell _ Load for activating the secondary carrierAct-thr. If Cell _ loadsecGreater than Cell _ LoadAct-thrThen, the process is ended directly. If step S30 occurs: if Cell _ loadsecLess than or equal to Cell _ LoadAct-thrAnd activating the secondary carrier of the UE of SC-HSUPA. The above algorithm for activating the secondary carrier is an algorithm for converting the SC-HSUPA service into the DC-HSUPA service. It can be seen that the method for activating the secondary carrier does not consider the factor of the UE buffer, so that the secondary carrier can be still activated when the data amount of the UE buffer is small. In addition, the method directly controls the activation of the secondary carrier in the base station, and is simple and more effective.
Preferably, the activating the secondary carrier of the SC-HSUPA UE in step S30 specifically includes: and the secondary carrier of the UE of the SC-HSUPA is activated regularly. The time length of the timer for activating the auxiliary carrier of the UE is set, for example, 10ms, so that the ping-pong effect generated by the DC-HSUPA and the SC-HSUPA can be effectively avoided.
Further, at step S10: checking SCPower headroom UPH on the primary carrier for a UE of HSUPApriWhether or not to be greater than or equal to threshold value UPH of power headroom of activated secondary carrierAct-thrPreviously, the user equipment UE selecting single carrier high speed uplink packet access SC-HSUPA may adopt the scheduling priority of the base station to the UE.
Second embodiment

And, set Cell _ LoadAct-thrFor example, the value can be configured to be 90% of the full load of the cell, and the simulation verification can be performed, and then some fine adjustment can be performed on the value according to the real data of the external field.
Third embodiment
As shown in fig. 3, the method for deactivating a secondary carrier provided in this embodiment specifically includes: step 50: checking power headroom UPH of DC-HSUPA UE on main carrier respectivelypriAnd power headroom on secondary carrier UPHsecWhether all are less than threshold value UPH of power margin for deactivating auxiliary carrierDeact-thr. UPH for deactivating secondary carriersDeact-thrMay be set to 23, Cell _ LoadDeact-thrMay be set to 95% of the full load of the cell. Step 60: if UPHpriAnd UPHsecAre all less than UPHDeact-thrThe secondary carrier of the UE of DC-HSUPA is directly deactivated. If there is a situation in step 70: if UPHpriAnd UPHsecAny one of not less than UPHDeact-thrFurther verifying Cell load of secondary carrier of DC-HSUPA UEsecWhether the Cell Load is larger than or equal to a threshold value Cell _ Load for deactivating the Cell Load of the secondary carrierDeact-thrAnd determines in the secondary carrierWhether the number of all users in the cell is greater than a set value M, wherein M is a positive integer, and then the step 80 is executed: if Cell _ loadsecCell _ Load or moreDeact-thrAnd if the number of all users in the auxiliary carrier cell is larger than M, calculating the user equipment unhappy UE with limited service authorization SG schedulable except the UE of the DC-HSUPA in the auxiliary carrier cell, if the SG of the unhappy UE is lifted by one step, obtaining the load increment delta L of the cell, and simultaneously calculating the cell load Li currently occupied by the UE of the DC-HSUPA. Step 90: judging whether DeltaL is more than or equal to Li. If Δ L is equal to or greater than Li, perform step 60: deactivating the secondary carrier of the DC-HSUPA UE. Likewise, the timer duration for deactivating the secondary carrier of the UE may be set, such as configurable 10ms, to avoid ping-pong effects between DC-HSUPA traffic and SC-HSUPA traffic. Purpose of step 80 and step 90: if the secondary carrier of the UE of the DC-HSUPA is deactivated, the released resources do not need to be deactivated to the secondary carrier if the resources cannot be fully utilized by other schedulable unhappy users on the cell of the secondary carrier, and the purpose of the deactivation is to fully utilize the resources.
The method for deactivating the auxiliary carrier adopts an algorithm for converting the DC-HSUPA service into the SC-HSUPA service. Similarly, the method for deactivating the secondary carrier does not consider the factor of the UE buffer, so that the secondary carrier can still be activated when the data amount of the UE buffer is small. In addition, the method directly controls the activation of the secondary carrier in the base station, and is simple and more effective.
Further, step 50: checking power headroom UPH of DC-HSUPA UE on main carrier respectivelypriAnd power headroom on secondary carrier UPHsecWhether or not the threshold value UPH of the power margin for deactivating the auxiliary carrier is smaller thanDeact-thrIn the past, the user equipment UE selecting the dual-carrier high-speed uplink packet to access the DC-HSUPA may adopt the scheduling priority of the base station to the UE.
