Problems solved by technology

Every time the secondary carrier is turned off and on, many unfavorable factors will be brought about, such as the loss of synchronization time, the feedback rearrangement of the HS-DPCCH physical feedback channel feedback information, and the participation of multiple RF receiving links of the UE in activities that lead to high power consumption, etc.

specific Embodiment 1

[0054] The second decision module is designed as the following logic synthesis operation, within the valid time of the constraints stipulated in the Valid DL forbid time period:

[0055] When the first judgment module outputs the "downlink secondary carrier activation command" and the value of the Forbid DL activation information element in the message carrying the secondary carrier state control condition sent by the RNC is false, the node B sends the "downlink secondary carrier activation command" to the terminal .

[0056] When the first decision module outputs the "downlink secondary carrier activation command" and the value of the Forbid DL activation information element in the message carrying the secondary carrier state control condition sent by the RNC is true, the Node B does not issue the "downlink secondary carrier activation command".

[0060] Design the second judgment module as the following logic synthesis operation, within the valid time limit specified in the Valid UL forbid time period:

[0061] When the first decision module outputs the "uplink secondary carrier activation command" and the value of the Forbid UL activation information element in the message carrying the secondary carrier state control condition sent by the RNC is false, the node B sends the "uplink secondary carrier activation command" to the terminal .

[0062] When the first decision module outputs the "uplink secondary carrier activation command" and the value of the Forbid UL activation information element in the message carrying the secondary carrier state control condition sent by the RNC is true, the Node B does not issue the "uplink secondary carrier activation command".

Abstract

The invention discloses a method and system for carrying out activation / deactivation control on a secondary carrier of a multicarrier network. The method comprises the following steps that: a wireless network controller sends a secondary carrier state control condition for indicating to allow or forbid to activate / deactivate the secondary carrier to a node B; the node B judges whether operation indicated by the secondary carrier state control condition is the same as operation indicated by a secondary carrier state control order or not; if so, the secondary carrier state control order is sent to the terminal; and if not, the secondary carrier state control order is forbidden to be sent. With the adoption of the method and the system provided by the invention, the flexibility configured to the carrier by the network is improved by controlling the node B through an RNC (Radio Network Controller).

Description

technical field [0001] The present invention relates to a wireless communication system or network with multi-carrier characteristics, in particular to a method and system for controlling the activation and deactivation of secondary carriers in a multi-carrier network. Background technique [0002] First, the abstract characteristics of the system or network with multi-carrier characteristics are given, as follows: In order to increase the data transmission rate between network element A and network element B in a certain communication period, multiple carriers are configured. The signal of network element A is transmitted to network element B through N (N>1) carriers, and the signal of network element B is transmitted to network element A through M (M>1) carriers at the same time. Among the N carriers of network element A, if a certain carrier is responsible for transmitting signals controlling all or part of the carriers of network element A, or is responsible for tr...
