Embodiment 1
[0075] Such as figure 1 Shown is a flow chart of the UE transmitting its supported multi-carrier capability to the RNC;
[0076] Step 101: UE sends its supported multi-carrier capability to RNC;
[0077] The UE may, but is not limited to, carry the supported multi-carrier capability in the RRC Connection Request (radio resource control connection request) message;
[0078] The multi-carrier capability supported above may refer to the number of carriers supported by the UE, or the number of secondary carriers supported by the UE;
[0079] The UE can send supported multi-carrier capabilities in the following ways:
[0080] (1) In the message carrying the supported multi-carrier capability (such as the radio resource control connection request message), add an indication information element (Multi Cell Support Number) of the number of carriers supported by the UE to indicate the number of carriers supported by the UE ;
[0081] The protocol description is shown in Table 1 or ...
Embodiment 2
[0103] After the RNC obtains the multi-carrier support capability of the UE, the RNC can allocate resources for the UE according to the multi-carrier support capability of the UE. The specific operation process is as follows: figure 2 As shown, it mainly includes the following steps:
[0104] Step 201, the RNC decides whether the service can be applied to multiple carriers according to information such as Quality of Service (QoS, Quality of Service) attributes, UE's ability to support multiple carriers and cell capabilities, and executes step 202 when the decision service supports multiple carriers.
[0105] Wherein, the QoS attribute is transmitted to the RNC by the core network (CN, Core Network) when delivering the service assignment, and the cell capability is acquired by the RNC through the audit response of the Node B (NodeB).
[0106] Step 202, the RNC carries the secondary carrier cell information (HS-DSCH FDD SecondaryServing Information) in the radio link establishm...
Embodiment 3
[0109] When the UE moves between cells controlled by two RNCs, the relocation process needs to go through the core network. The specific operation process is as follows: image 3 As shown, it mainly includes the following steps:
[0110] Step 301, the source radio network controller SRNC initiates a relocation requirement message Relocation Required to the core network CN, which carries a transparent container (Source To Target Transparent Container) from the source radio network controller to the target radio network controller, the source radio network controller The transparent container from the device to the target radio network controller includes a radio resource control container, and the radio resource control container includes the multi-carrier capability supported by the UE.
[0111] Step 302, the core network CN initiates a relocation request message Relocation Request to the target radio network controller DRNC, which carries a transparent container (Source To Targ...
