Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] figure 1 It is a flowchart of a radio resource management method for a multi-band network according to the present invention. The present invention adds a frequency band indication message in the broadcast message to inform the user equipment (UE) whether cells in different frequency bands can be detected around. Report whether multiple frequency bands are supported in the user equipment capability, so that the radio network controller (RNC) can know in time whether the cell being accessed supports multiple frequency bands, so as to decide whether to notify the UE of a list of possible different frequency bands; When measuring control messages, these event threshold parameters are filled in differently according to UE capability information. The cell information of different frequency bands is added to the adjacent cell l...

Abstract

The invention provides a wireless resource management method which is applied to the multi-frequency network and the system thereof. The method includes steps as following: step 1, a wireless network controller sends the broadcast message along with frequency band direction message to a user device, so as to inform the user device of whether to detect different frequency subdistrict or not in surrounding, the user device submits the user device capacity message to the wireless network controller, wherein, the message which to support the multi frequency or not is added into the user device capacity message; step 2, the wireless network controller ensures whether to inform the user device of the possibly existent different frequency list according to different frequency distribution and the user device capacity message, if needing to inform, the different frequency subdistrict message and the measuring control message are added into the adjacent subdistrict list to send to the user device; step 3, the user device measures the different frequency subdistrict and sends the measuring result to the wireless network controller; step 4, according to the measuring result, the wireless network controller switches between frequencies, or dictates the user device to reelect the different frequency subdistrict.

Description

technical field [0001] The present invention relates to the communication field, in particular to a radio resource management method and system for a multi-band network, a radio network controller and user equipment. Background technique [0002] In 1992, ITU allocated 230MHz bandwidth for the third-generation mobile communication service at the WARC-92 conference: 1885-2025MHz (40M) as the uplink frequency band of IMT-2000, and 2110-2200MHz (90M) as the downlink frequency band. Among them, the uplink of FDD (including WCDMA and CDMA2000) uses 1920-1980MHz (60M), and the downlink uses 2110-2170MHz (60M). The TDD mode (including TD-SCDMA and UTRA TDD) uses 2010~2025MHz (15M), and does not distinguish between uplink and downlink. 1980-2010MHz (30M) and 2170-2200MHz (30M) are respectively used as uplink and downlink frequency bands for mobile satellite services. [0003] With the acceleration of the commercialization process of TD-SCDMA system, the 15M bandwidth allocated to ...
