Problems solved by technology

It can be seen from the above description that because there is no processing of the information related to the coverage of the cell exchanged between the RNC and the NodeB, the RNC cannot obtain the positioning format in the relevant information, and thus cannot locate the UE; nor can it obtain the coverage of the cell. Therefore, it cannot be guaranteed that the transmit power of NodeB can cover the entire cell

Embodiment Construction

[0045] The scheme of the present invention mainly transmits the information related to the coverage range of the cell between the NodeB and the RNC. In the first solution, the NodeB actively reports the information about the cell coverage, and in the second solution, the RNC allocates the information about the cell coverage to the NodeB and sends it to the NodeB.

[0046] The cell coverage-related information may be cell coverage information, or may be a positioning format. Wherein, the positioning element used for positioning the UE may use PD, and may further use RTT, and the positioning formats of PD and RTT both include a field length and a unit. The corresponding cell coverage can be expanded by only modifying the field length of PD and RTT, or the corresponding cell coverage can be expanded by only modifying the unit of PD and RTT.

[0047] The two implementation schemes of the present invention will be described in detail below with reference to the drawings and specif...

Abstract

The invention relates to a method for confirming the information of region cover range, wherein it adds report word in the message sent to wireless network controller from base station; and it also comprises that: a, base station sets information of region cover range, via the added report word to send said information to the wireless network controller; b, wireless network controller via the information confirms the region cover range. The invention also discloses another method for confirming the information of region cover range. With said invention, RNC can obtain accurate region cover range information.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for determining information related to cell coverage. Background technique [0002] The Wideband Code Division Multiple Access (WCDMA) network can pass the transmission delay (PD, Propagation Delay) of the Physical Random Access Channel (PRACH, Physical Random Access Channel) and the loopback time ( RTT, Round Trip Time) to locate the UE. [0003] PD represents the one-way transmission delay of the air interface. NodeB transmits the PD value currently required by UE to RNC in the form of FP packet, and RNC can determine the location of the UE according to the PD value, and configure a dedicated channel for the UE according to the PD value when necessary. In the frequency division duplex (FDD) system of WCDMA, PD can be obtained through PRACH channel measurement. The range of PD is 0 to 765, and the unit is 3chips. When the value of PD is greater than 76...
