DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. The invention provides an intelligent carrier breaking method. FIG. 1 is a flowchart of an intelligent carrier breaking method according to an embodiment of the present invention. As shown in FIG. 1, the following steps S102 to S104 are included. Step S102, determining that the cell performs smart carrier breaking. Step S104, processing a multi-carrier service in which a carrier exists in the cell. In the related art, the intelligent carrier breaking may affect the normal operation of the multi-carrier service, causing the service to drop. In the embodiment of the present invention, after determining that the cell performs the intelligent carrier breaking, the multi-carrier service in which the carrier exists in the cell is processed in time, thereby avoiding service dropped calls and improving the user experience. In order to more clearly describe the processing of the multi-carrier service, the embodiment of the present invention divides the multi-carrier service into a multi-carrier service in which a secondary carrier exists in the cell and a multi-carrier service in which a primary carrier exists in the cell. They are described separately below.

(1) The carrier processing of the multi-carrier service in which the secondary carrier is present in the cell may be performed by using the Node B and the Radio Network Controller (RNC) as the main body, and may be divided into the smart carrier to be turned off. On and the smart carrier is disconnected to open. They are described separately below.

1. In the case that the smart carrier is turned on to the smart carrier disconnection, the Node B performs carrier deactivation on the multi-carrier service in which the secondary carrier exists in the cell through the HSSCCH ORDER mode.

2. In the case that the smart carrier is disconnected to the smart carrier, the Node B performs carrier activation on the multi-carrier service in which the secondary carrier exists in the cell through the HSSCCH ORDER mode. It should be noted that, by using the HSSCCH ORDER mode, the RNC can perform signaling reconfiguration participation for all terminals on a certain carrier at the same time, thereby avoiding service dropped calls and ensuring network performance. 3. When the smart carrier is turned on and the smart carrier is disconnected, the RNC configures the multi-carrier service in which the secondary carrier exists in the cell as a single carrier service through the Radiobearer message. 4. When the smart carrier is disconnected to the smart carrier, the RNC configures the single carrier service with the secondary carrier in the cell as a multi-carrier service through the Radiobearer message.

(2) The scheduling process for the multi-carrier service in which the primary carrier exists in the cell can be divided into two cases: smart carrier on-off and smart carrier off-to-on. They are described separately below. 1. In the case that the smart carrier is turned on to the smart carrier disconnection, the scheduling process is stopped for the multi-carrier service.

2. In the case that the smart carrier is disconnected to the smart carrier, the scheduling processing is resumed for the multi-carrier service. It should be noted that the stop scheduling process and the resume scheduling process may be performed by the node B or by the RNC. In addition, the embodiment of the present invention may determine that the cell performs smart carrier breaking by determining that the pilot power variation of the cell is a preset threshold. Specifically, when the RNC continuously sends the cell reconfiguration signaling to the NodeB, until the pilot power is reconfigured to the foregoing preset threshold (for example, -100dbm), the NodeB may determine that the cell performs the smart carrier from on to off; When the RNC continuously retransmits the cell pilot channel and the common transport channel to the cell physical channel configuration value by continuously transmitting cell reconfiguration signaling to the NodeB, the NodeB may determine that the cell performs the smart carrier from off to on. The implementation process of the embodiment of the present invention will be described in detail below with reference to examples. FIG. 2 is a schematic diagram of an intelligent carrier breaking method according to an example 1 of the present invention. As shown in FIG. 2, the HSSCCH ORDER (High Speed Control Channel Command) is used for the DC-HSDPA terminal user secondary carrier deactivation mode, and only the primary carrier is performed. Scheduling processing; When the smart carrier is turned on, if the DC-HSDPA terminal user secondary carrier is not activated, the secondary carrier is activated by the HSSCCH ORDER, thereby performing multi-carrier scheduling processing to improve performance. With this method, the RNC (Radio Network Controller) does not need to perform signaling reconfiguration participation for all terminals on a certain carrier at the same time, which may cause network performance degradation due to service drop.

A): When the smart carrier is turned on to the smart carrier disconnection: 1: The RNC passes the continuous cell reconfiguration signaling to the NodeB, until the pilot power is reconfigured to a certain value (can be set to -lOOdbm);

2: For this cell whose pilot is reduced to -lOOdbm: a: For the single-carrier user of the cell and the user of the dual-carrier and multi-carrier users whose primary cell is the cell, the scheduling process is stopped, so that the terminal can automatically initiate the same-frequency or inter-frequency handover to other cells; b: for the secondary carrier The dual carrier and multi-carrier UE of the cell performs secondary carrier deactivation through the HSSCCH ORDER mode. B): When the smart carrier is disconnected until the smart carrier is turned on:

1: The RNC retransmits the cell pilot channel and the common transport channel to the cell physical channel configuration value by using cell reconfiguration signaling to the NodeB;

2: The processing for the carrier cell is as follows: a: re-schedule processing for the single-carrier user of the cell and the user of the dual-carrier and multi-carrier user whose primary cell is the cell; b: the dual carrier for the secondary carrier in the cell and The multi-carrier UE performs secondary carrier activation in the HSSCCH ORDER mode, and can perform scheduling processing on the carrier. Example 2 FIG. 3 is a schematic diagram of an intelligent carrier breaking method according to Example 2 of the present invention. As shown in FIG. 3, the RNC operates in a signaling control manner when the intelligent carrier is turned off and turned on.

A): When the smart carrier is turned on to the smart carrier disconnection:

1: The RNC passes the constant cell reconfiguration signaling to the NodeB, until the pilot power is reconfigured to a certain value (can be set to -lOOdbm);

2: The cell with the pilot reduced to -lOOdbm is processed: a: for the single-carrier user of the cell and the user of the dual-carrier and multi-carrier user whose primary cell is the cell stops scheduling, so that the terminal can automatically initiate the same frequency Or inter-frequency handover to other cells; b: For the dual-carrier and multi-carrier UEs of the secondary carrier in the cell, the RNC performs the following signaling operations on the UEs: by re-allocating the NodeB radio link and the radio bearer to the UE With RadiobearerRecfg, the corresponding DC-HSDPAUE is reconfigured to become SC-HSDPAUE. B): When the smart carrier is turned off to the smart carrier is turned on:

2: The processing for the carrier cell is as follows: a: re-scheduling the single-carrier user in the cell; b: the dual-carrier and multi-carrier UEs can be supported on the cell, and the RNC performs the following signaling operations on the UE: The radio link reconfiguration and the RadiobearerRecfg for the UE reconfigure the corresponding SC-HSDPA UE into a DC-HSDPA UE. The embodiment of the present invention proposes that in the case of an intelligent carrier switch, the UMTS HSPA+ includes a DC-HSDPA (dual carrier) and a subsequent MC-HSDPA processing solution, which ensures that in the case of an intelligent carrier switch, the dual carrier and multi-carrier services can be not affected. Normal operation does not affect network performance. Therefore, the impact on the business in the case of intelligent carrier shutdown is well solved.
