Description

Test method and device when user i prepares high-speed mobile This application claims to be submitted to the Chinese Patent Office on June 10, 2011, application number 201110156427.7, and the Chinese patent entitled "Testing Method and Device for High-speed Mobile of User Equipment" Priority of the application, the entire contents of which are incorporated herein by reference. Technical field

The present invention relates to the field of mobile communications, and in particular, to a test method and apparatus for user equipment moving at high speed. BACKGROUND When a user equipment (UE) such as a mobile phone is in a moving state during communication, the frequency of the received signal changes. This situation in which the signal frequency changes due to motion is called a Doppler effect. The Doppler effect is a characteristic of any wave process, and the additional frequency caused by it is called Doppler shift, which can be expressed by:

f

ΐ =― *v*cos<

d C In the above formula, v is the velocity of motion, / is the frequency, C is the propagation velocity of the radio wave (equal to the speed of light in the vacuum), and Θ is the angle between the incident wave and the direction of motion of the mobile terminal.

According to the above principle, when the UE is in the handover area between two adjacent base stations, the actual frequencies of the downlink signals of the base station 1 and the base station 2 received by the UE side are "/ 0 - / d" and "/ 0 + / d", as shown in Figure 1, wherein the frequency of the base station is /0. Assuming that the UE frequency is locked to the primary serving cell on the left side of the figure, that is, "/ 0 - / d", the frequencies after the signal transmitted by the UE reaches the base station 1 and the base station 2 are "/ 0 - 2/d" and '0, respectively. - / d + / d" , ie "f 0 - 2/ d" and "f 0". After the UE's signal arrives at both base stations, there will be a relative frequency difference of "2 / d". Ignored in the above analysis. The fixed frequency offset of the uplink and downlink frequency points. In the actual network, for example, the 2.1 GHz frequency band, there is a fixed frequency offset of 190M in the uplink and downlink. One test method in the prior art is to simulate a channel model by a channel simulator, which requires an increase in the channel model for uplink or downlink. Because the Doppler effect exists in the actual mobile communication process, the test method provided by the prior art cannot simulate the situation in which the uplink and downlink signals in the real frequency are both frequency offset, and it is also impossible to simulate the UE moving between two cells. The scene of the time, the scope of application is limited.

The execution body may be a power attenuating device, for example, an adjustable attenuator or the like. The method illustrated in Figure 2 mainly includes the steps of:

S201. Receive a signal preset from a first radio frequency module and/or a second radio frequency module and preset a Doppler frequency offset.

In the embodiment of the present invention, the first radio frequency module or the second radio frequency module is a module capable of transmitting a radio frequency signal and receiving a radio frequency signal, similar to a base station device in actual mobile communication. In order to simulate the scenario of the actual mobile communication, in the embodiment of the present invention, the frequency of the transmitted signal of the first radio frequency module is preset to /. - / d, to simulate the downlink signal of one of the two base stations in the actual mobile communication, and preset the frequency of the transmission signal of the second radio frequency module to /Q + /d to simulate two of the actual mobile communication The downlink signal of another base station in the base station. here /. For the actual frequency of the base station, / d is the Doppler shift, / d is calculated according to the following formula:

f

f. =― * v* cos< ,

d C Where V is the moving speed of the user equipment in actual mobile communication, / is the frequency of the base station in actual mobile communication, C is the propagation speed of the radio wave, and Θ is the angle between the incident radio wave of the base station and the moving direction of the user equipment.

After receiving the transmitted signals from the first radio frequency module and/or the second radio frequency module, the power attenuating device receives, for example, the first radio frequency module and the frequency point is preset to /. - / d transmit signals, and / or receive transmit signals from the second RF module with a frequency preset of / Q + / d to adjust the transmit power of these signals.

S202. The signal that is preset to the Doppler frequency offset is adjusted and sent to the user equipment to obtain the receiving condition of the adjusted signal by the user equipment.

In the embodiment of the present invention, it is assumed that the first radio frequency module is one of two base stations.

B 1 , the second radio frequency module is one of the two base stations B2.

In order to simulate that the user equipment is in a certain cell in the actual mobile communication, in one embodiment of the present invention, the power of the signal from the first radio frequency module and preset by the Doppler frequency offset may be increased to simulate that the user equipment is in a certain Community. For example, set the frequency to /. - The power of the transmitted signal of the first radio frequency module of - / d is sent to the user equipment, and the user equipment in the actual mobile communication is simulated to be in the cell to which the base station B1 belongs; in another embodiment of the present invention, the second The radio frequency module presets the power of the Doppler frequency offset signal to simulate that the user equipment is in a certain cell. For example, set the frequency to /. The power of the transmitted signal of the second radio module of + / d is transmitted to the user equipment, and the user equipment in the actual mobile communication can be simulated to be in the cell to which the base station B2 belongs.

In order to simulate the switching of user equipment between two cells in actual mobile communication, in one embodiment of the present invention, the power of the signal from the first radio frequency module and preset Doppler frequency offset can be increased and reduced from the first The second radio frequency module presets the power of the Doppler frequency offset signal, thereby simulating the user equipment to switch between the two cells. For example, set the frequency to /. - / d The power of the transmitted signal of the first RF module is increased, and at the same time, reducing the power of the transmitted signal of the second RF module with a frequency of /0 + /d will increase the power and decrease The power transmission signal is sent to The user equipment can simulate that the user equipment in the actual mobile communication is moving from the cell to which the base station B2 belongs to the cell to which the base station B1 belongs, and finally to the cell to which the base station B1 belongs to the cell to which the base station B1 belongs.

In the embodiment of the present invention, the retransmission mechanism may also be introduced, that is, when the signal for adjusting the preset Doppler frequency offset is transmitted to the user equipment, the data sent to the user equipment is recorded in real time. When the user equipment receives an abnormality, it requests the power attenuating device side to retransmit the data through the ARQ or HARQ mechanism.
