METHOD FOR MODIFYING MULTIPLE INPUT MULTIPLE OUTPUT MODE ACROSS RADIO NETWORK CONTROLLERS

摘要

A method for modifying Multiple Input Multiple Output (MIMO) mode across Radio Network Controllers (RNCs) is provided by the present disclosure. In the method of the present disclosure, a Serving RNC (SRNC) transmits a request message to a Drift RNC (DRNC), wherein the request message requests the DRNC to set a radio link for a mobile equipment in a cell controlled by the DRNC, and the DRNC feeds back a response message to the SRNC based on the capability of the DRNC and the cell controlled by the DRNC, wherein the response message contains the element used for configuring the radio link in the non-MIMO mode. As a result, when the DRNC and the cell controlled by the DRNC support the MIMO mode, the SRNC configures the radio link to be in the MIMO mode for the mobile equipment, and when the DRNC and the cell controlled by the DRNC do not support the MIMO mode, the SRNC configures the radio link to be in the non-MIMO mode for the mobile equipment. Therefore, a mobile equipment handover or a radio link reconfiguration is completed, and the success rate of the handover or the configuration is improved.

1. A method for modifying Multiple Input Multiple Output (MIMO) mode across Radio Network Controllers (RNCs), comprising:
a Serving RNC (SRNC) transmitting a request message to a Drift RNC (DRNC), wherein the request message requests the DRNC to set a radio link for a current mobile equipment in a cell controlled by the DRNC, and the request message contains an element which requests the DRNC to configure the radio link to be in the MIMO mode; and the SRNC receiving a response message fed back by the DRNC regarding the request message, and judging whether the response message contains an element which requests the SRNC to configure the radio link to be in a non-MIMO mode, if the response message contains the element which requests the SRNC to configure the radio link to be in the non-MIMO mode, then notifying the mobile equipment to configure the radio link to be in the non-MIMO mode, and otherwise, then notifying the mobile equipment to configure the radio link to be in the MIMO mode.
