Description

Measurement result reporting method, system and equipment

technical field

The invention relates to mobile communication technology, in particular to a method, system and equipment for reporting channel quality measurement results in a communication system.

Background technique

In the protocol version of R7, the enhanced function of common channel data transmission state (CELL-FACH) is introduced, and the user terminal (UE, User Equipment) supports the high-speed downlink shared channel (HS-DSCH, High Speed Downlink Shared Channel) to receive downlink data. In the uplink direction, the UE needs to report whether the transmitted data is received correctly, and the measured current pilot channel quality and other information. Since the uplink of CELL_FACH adopts random access channel (RACH, Random Access Channel), feedback information such as channel quality indication (CQI, Channel Quality Indication) and acknowledgment (ACK) cannot be transmitted, so the UE can only report the corresponding measurement results through the RACH channel .

FIG. 1 is a schematic diagram of reporting a measurement result by an existing UE. As shown in Figure 1, the UE, according to the relevant parameters configured in the system information block (SIB, System Information Type) 11/SIB12 broadcast in the cell, such as information related to cell selection, same-frequency measurement indication, or inter-frequency measurement indication, etc., Measure parameters such as received signal power code (RSCP, Received Signal Code Power) or chip energy (Ec)/noise power density (N0) of the pilot channel, and during UE position changes or periodic cell update (Cell Update) process In this method, the measurement result is reported to the radio network controller (RNC, Radio Network Controller) through the Cell Update message sent on the RACH channel. The RNC carries the measurement results received from the RACH channel in the "Transmit Power Level" header field of the HS-DSCH frame protocol (FP, Frame Protocol) data frame header and sends it to the base station (NodeB). NodeB performs scheduling according to the measurement results, such as configuring multi-channel selection (MCS, MCS, Multiple Channel Select) and transmission power, etc.

In the solution shown in Figure 1, although the UE can measure the RSCP or Ec/N0 of the pilot channel in real time according to the parameters in the system message SIB11/SIB12, the measured results can only be reported to the RNC during the Cell Update process. In this way, when the channel environment changes and the originally reported measurement results no longer conform to the current channel environment, if the Cell Update message is not sent, the UE cannot report the new measurement results to the RNC, resulting in the NodeB being unable to make decisions based on the current channel environment. Scheduling in line with the current situation will affect the quality of service (QoS, Quality of Service) of the network.

Detailed ways

In the embodiment of the present invention, the current parameter of the pilot channel is measured to obtain the current measurement result; the current measurement result is compared with the saved measurement result, and when the comparison result meets the reporting condition, the current measurement result is reported.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

Fig. 2 is a flow chart of the first embodiment of the method of the present invention. As shown in Figure 2, the following steps may be included:

201: Measure the current parameter of the pilot channel, and obtain the current measurement result.

In this step, the UE obtains the current measurement result by measuring the current parameter of the pilot channel. A specific measurement method may adopt a measurement method in the prior art. How to perform the measurement is not the key to realizing the solution of the present invention, and will not be repeated here.

Wherein, the pilot channel parameter may be RSCP, or Ec/N0 and so on.

202: Compare the current measurement result with the saved measurement result, and report the current measurement result when the comparison result satisfies the reporting condition.

In this step, the current measurement result is compared with the pre-saved previously reported measurement result, for example, it is judged whether the absolute value of the difference between the two is greater than or equal to the preset reporting threshold, and if so, the current measurement result is reported , otherwise, do not report. For the measurement result obtained from the first measurement, since there is no corresponding measurement result reported last time, it may be directly reported without comparison.

In practical applications, the measurement and comparison described in 201 and 202 can be completed by the UE alone, or jointly by the UE and the RNC. When the comparison result meets the reporting condition, the RNC reports the current measurement result to the NodeB. Wherein, the measurement is completed by the UE, and the comparison can be completed by either the UE or the RNC.

It should be noted that the embodiment shown in FIG. 2 is only for illustration and is not intended to limit the technical solution of the present invention. For example, in practical applications, the reporting condition mentioned in 202 may also be that as long as the current measurement result is different from the saved measurement result, the reporting is performed without comparing with the reporting threshold. Moreover, when making the comparison, in addition to comparing the current measurement result with the pre-saved previously reported measurement result, other known comparison methods may also be used.

It can be seen that compared with the prior art, the solution described in the embodiment of the present invention is no longer limited to reporting the measurement results of the frequency channel during the CellUpdate process, but after obtaining the measurement results of the pilot channel, if it is determined through comparison that the pre-defined The set reporting conditions are reported, so that the subsequent NodeB can perform scheduling in accordance with the current channel environment in time according to the received measurement results, and improve the network service quality.

The scheme of the present invention will be further described in detail through specific examples below.

Fig. 3 is a flow chart of the second embodiment of the method of the present invention. In this embodiment, the UE simultaneously completes the measurement and comparison functions. In this embodiment, the UE measures the current parameters of the pilot channel in real time, such as the value of RSCP or Ec/N0, obtains the current measurement result, and compares the current measurement result with the previously saved measurement result reported last time, and according to the comparison The result determines whether to report the current measurement result. As shown in Figure 3, the following steps may be included:

301: The UE measures current parameters of a pilot channel to obtain a current measurement result.

Before this step, it may further include: the RNC sends the extended system message SIB11/SIB12 to the UE through cell broadcast. The extension mentioned here refers to the addition of two information elements in the system message SIB11/SIB12, one of which is used to carry the information indicating whether the UE needs to report the measurement result according to the change of the channel environment, and the other is used to carry the report condition. Wherein, the indication information may be set to 0 or 1. For example, when the indication information is 1, it means that the RNC needs the UE to report the current measurement result according to the channel environment change; when the indication information is 0, it means that the RNC does not require the UE to report the current measurement result according to the channel environment change. When the RNC does not require the UE to report the current measurement result according to channel environment changes, the information element carrying the reporting condition information can be set to be empty.

For example, in this embodiment, the first information element may carry information indicating whether the UE needs to perform difference detection and reporting according to the current measurement result and the previous saved measurement result, and the other information element may be used to carry reporting threshold information.

In the above process, the RNC may determine whether the UE needs to report the current measurement result according to the difference according to the actual situation. For example, if the RNC determines that the UE is in the CELL_FACH enhanced state, it may determine that the UE needs to report the current measurement result according to the difference.

The UE measures the current parameters of the pilot channel according to the indication information carried in the received system message SIB11/SIB12.

302: The UE calculates the absolute value of the difference between the current measurement result and the saved measurement result reported last time.

303: The UE compares whether the calculated absolute value of the difference is greater than or equal to the preset reporting threshold, and if yes, executes 304; otherwise, returns to execute 301.

The preset reporting threshold mentioned in this step is the reporting threshold carried in the system message SIB11/SIB12 issued by the RNC to the UE. The UE compares whether the absolute value of the difference between the current measurement result and the previous reported measurement result is greater than or equal to the reporting threshold, and performs different operations according to the comparison result: if yes, perform 304; otherwise, consider the change of the current channel environment It will not obviously affect the scheduling of NodeB, ignore this change, and return to execute 301.

Normally, the value of the reporting threshold can be set to 4-10dB, but in practical applications, the specific value of the reporting threshold needs to be determined according to the use environment and network conditions at that time.

304: The UE reports the current measurement result to the NodeB through the RNC.

In this step, how to report the measurement result can refer to the method in the prior art, and will not be repeated here.

Furthermore, in the subsequent process, the NodeB can perform scheduling according to the received measurement results, such as reconfiguring the number of retransmissions and transmit power for the UE. How to perform scheduling is a prior art and will not be repeated here.

305: The UE updates the saved measurement result, and then returns to 301.

The UE uses the current measurement result reported this time to update the saved measurement result of the previous report for the next comparison, and then returns to 301, that is, measures the current parameter of the pilot channel again, and determines whether to report it according to the situation, here No longer.

It should be noted that what is shown in FIG. 3 is only for illustration and is not intended to limit the technical solution of the present invention. For example, before 301, the RNC sends the indication to the UE whether to perform difference detection and reporting and the reporting threshold information. In addition to carrying the system information SIB11/SIB12 described in Figure 3, it can also be carried through the dedicated Uu interface. The measurement control message or a self-defined message is carried, and the specific implementation manner is not limited. Moreover, the solution described in the embodiment of the present invention is not only applicable to the CELL_FACH enhanced state, but also applicable to other radio resource control (RRC, Radio Resource Control) states, such as the cell-dedicated connection (CELL_DCH, CELL Dedicated Channel) state.

The embodiment shown in FIG. 3 is an implementation process of the solution of the present invention when the UE independently completes the measurement and comparison. In practical applications, the UE may also complete the measurement, and the RNC may complete the comparison. The specific implementation can be as follows:

The RNC sends a message to the UE, and the message carries an indication of whether periodic reporting is required, and reporting period information.

The sent message may be the system message SIB11/SIB12 mentioned in the embodiment shown in FIG. 3 , or a dedicated measurement control message through the Uu interface, or a self-defined message.

The UE measures the current parameters of the pilot channel, obtains the current measurement result, and periodically reports the current measurement result to the RNC; the RNC compares whether the absolute value of the difference between the current measurement result and the previously reported measurement result saved by itself is greater than or equal to the set reporting threshold, if yes, the RNC reports the current measurement result to the NodeB.

Or, the UE measures the current parameters of the pilot channel, obtains the current measurement result, and periodically calculates the difference between the current measurement result and the pre-saved previously reported measurement result, and reports it to the RNC; the RNC compares the received difference Whether the absolute value of is greater than or equal to the set reporting threshold, and if so, report the current measurement result to the NodeB.

Wherein, the UE can report the current measurement result while reporting the calculated difference to the RNC, so that the subsequent RNC can report the current measurement result to the NodeB; If the difference is reported, the difference is added to the measurement result reported for the first time to obtain the current measurement result.

It can be seen that when the comparison is completed by the RNC, the current measurement result of the pilot channel can also be reported to the NodeB in time, so that the subsequent NodeB can perform scheduling in accordance with the current channel environment in time according to the received measurement result, and improve network service quality.
