Embodiment 1

[0039] This embodiment describes how DRNC and SRNC transfer the auxiliary frequency status, such as figure 1 shown, including the following steps:

[0040] Step 101, the SRNC initiates an information exchange initialization request to the DRNC, wherein the object type of the information exchange is a UTRAN (UMTS Terrestrial Radio Access Network, UMTS Terrestrial Radio Access Network) cell, the information type is the coordinator state, and the reporting rule is reported when changing;

[0041] By setting the information type as the tutoring status, the DRNC will report the tutoring status information to the SRNC when the tutoring status changes. In other embodiments, the object type of information exchange may also be set to other values, which are determined by the wireless technology adopted by the cell. In addition, the reporting rule can also be set to report periodically, and at this time, the reporting cycle can be set to be shorter, so that the SRNC can know the tutori...

Embodiment 2

[0047] Such as figure 2 shown, including the following steps:

[0048] Step 201, the UE establishes a service in the SRNC using MIMO mode;

[0049] Step 202, the DRNC side cell takes place to deactivate the pilot frequency;

[0050] Step 203, the DRNC reports an information report to the SRNC, carrying cell pilot frequency status information, and taking a value of pilot frequency deactivation, which means that the pilot frequency is unavailable;

[0051] Step 204, when the UE gradually moves to the DRNC side cell, report a measurement report to the SRNC indicating that the cell with the best signal quality is the DRNC cell;

[0052] Step 205, when the UE is handed over to the DRNC side cell, the SRNC initiates a wireless link establishment procedure on the Iur interface, and at the same time reconfigures the UE to a non-MIMO mode.

[0053] Since the SRNC knows that the pilot frequency of the cell on the DRNC side is unavailable, it reconfigures the UE to the non-MIMO mode....

Embodiment 3

[0056] Such as image 3 shown, including the following steps:

[0057] Step 301, the UE uses the non-MIMO mode to establish services, and switches to the DRNC cell, that is, the HS-DSCH serving cell is the DRNC side cell;

[0058] Step 302, the DRNC side cell takes place to deactivate the pilot frequency;

[0059] Step 303, the DRNC reports an information report to the SRNC, carrying cell pilot frequency status information, and takes the value of pilot frequency deactivation;

[0060] Step 304, when the SRNC initiates a wireless link reconfiguration process on the Iur interface, the SRNC does not reconfigure the MIMO mode of the UE, and keeps the UE in the non-MIMO mode.

Abstract

The present invention discloses a multiple-input multiple-output mode judgment method and a wireless network controller. When the cell under the jurisdiction of the DRNC of the UE closes the secondary antenna or deactivates the auxiliary frequency channel, the UE is prevented from switching or reconfiguration due to the use of the MIMO mode. The problem of failure. The method includes: when the first RNC closes the auxiliary antenna or deactivates the auxiliary frequency channel for the cell under its jurisdiction, sends the auxiliary frequency state information of the cell to the second RNC adjacent to the first RNC; when the first RNC is The drift RNC of the UE with MIMO capability, when the second RNC is the serving RNC of the UE, the second RNC judges the guidance of the first RNC side cell when establishing or reconfiguring the radio link for the UE If the secondary frequency state information of the cell indicates that it is unavailable, configure the UE in a non-MIMO mode.

Description

technical field [0001] The invention relates to a wideband code division multiple access (WCDMA) mobile communication technology, in particular to a judgment method of a multi-input multi-output mode and a wireless network controller. Background technique [0002] The secondary antenna is turned off or the auxiliary frequency is deactivated, which means that in a cell that supports multiple input multiple output technology (Multiple Input Multiple Output, MIMO), the number of user equipment (User Equipment, UE) that does not activate MIMO or that activates MIMO is small In the case of the situation, turn off the secondary antenna or deactivate the secondary frequency channel to achieve energy saving and reduce interference technology. The operation of closing or opening the secondary antenna or deactivating or activating the secondary frequency may be triggered by a radio network controller (RadioNetwork Controller, RNC) or a node B (Node B). The basic principles of the two...
