Embodiment 1

[0058] image 3 It is a flow chart of the long-term evolution frequency point measurement reporting method according to the preferred embodiment 1 of the present invention, such as image 3 As shown, the following steps S302 to S310 are included.

[0059] In step S302, the terminal reports to the 3G network controller RNC its ability to support the measurement of the target LTE frequency point in the public connection state through a common control channel (Common Control Channel, CCCH for short) cell update message Cell Update. Optionally, the capability level indication is: the terminal can complete the synchronization of a single target LTE frequency point and the scanning and measurement of all serving cells within 3s.

[0060] Step S304, according to the capability of the above-mentioned terminal, the RNC uses the cell update confirmation message Cell Update Confirm of the dedicated channel DCCH to send the 4 LTE frequency point information [F2, F3, F4, F5] to be tested ...

Embodiment 2

[0065] Figure 4 It is a flow chart of the long-term evolution frequency point measurement reporting method according to the preferred embodiment 2 of the present invention, such as Figure 4 As shown, the following steps S402 to S410 are included.

[0066] In step S402, the terminal reports to the 3G network controller RNC its ability to support the measurement of the target LTE frequency point in the public connection state through the cell update message Cell Update on the common uplink channel CCCH. Optionally, the capability level indication is: the terminal can complete the synchronization of a single target LTE frequency point and the scanning and measurement of all serving cells within 5s.

[0067] Step S404, according to the capability of the above-mentioned terminal, the RNC uses the measurement control message measurement control of the dedicated channel DCCH to send the 4 target LTE frequency point information [F6, F7, F8, F9] and a maximum measurement time value ...

Abstract

The invention discloses a method, a device and a system for measurement report of long-term evolution frequency points. The method comprises the following steps: a terminal in a universal mobile telecommunication system (UMTS) public connection state receives frequency point information and a maximum measurement report time value of a long term evolution (LTE) frequency point to be measured from a radio network controller (RNC), wherein the maximum measurement report time value is the longest time value which is allocated by the RNC to the terminal and used for the measurement report of the LTE frequency point to be measured, and the maximum measurement report time value corresponds to the time needed by the terminal for measuring the single LTE frequency point to be measured; and then the terminal carries out the measurement report of the LTE frequency point to be measured according to the frequency point information in the maximum measurement report time value. According to the method, the device and the system for the measurement report of the long-term evolution frequency points, the terminal in the public connection state carries out the measurement report of the LTE frequency point to be measured in the maximum measurement report time value which is allocated by the RNC so that the RNC can obtain wireless quality information of the LTE frequency point to be measured, and therefore the reliable movement of the terminal from a UMTS to an LTE system is guaranteed.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method, device and system for measuring and reporting long-term evolution frequency points. Background technique [0002] In the Universal Mobile Telecommunications System (UMTS for short) 3G network, the Universal Terrestrial Radio Access Network (UTRAN for short) includes a Radio Network Controller (RNC for short) and base station NodeB (NB) two basic network elements. In a Long Term Evolution (LTE for short) 4G network, an evolved universal terrestrial radio access network (Evoluted Universal Terrestrial Radio Access Network, E-UTRAN for short) includes an evolved base station eNodeB (eNB), a basic network element. In the long-term process of the evolution of the 3G UMTS network deployed by the operator to the 4G LTE network, there must be a long period of time. The two systems coexist and work together to jointly undertake the downlink or transmission from or to the ...
