Description
Technical Field
The present invention relates to wireless communication technologies, and in particular, to a method, a system, and an apparatus for performing measurement.
Background
For TD-SCDMA (Time Division Synchronized Code Division multiple access, Time Division synchronous CDMA system), the current protocol specifies that in CELL _ FACH (CELL forward access state) state and CELL _ DCH (CELL dedicated channel state), when a User Equipment (UE) receives a neighboring CELL list of co-frequency, inter-frequency, or inter-system configured by a network, it needs to perform co-frequency, inter-frequency, or inter-system measurement.
An RNC (Radio Network Controller) configures a list of cells of the same frequency, different frequency, or different systems to a user terminal through a broadcast message or a measurement control message. When the terminal receives the list information, it knows the information of the neighboring cells, such as frequency information and scrambling code. So that the terminal can uniquely determine a neighbor cell. The RNC also configures the quantity to be measured to the terminal through a broadcast message or a measurement control message, and the user terminal measures the quantity to be measured in the determined neighbor cell.
The network side can send a neighboring cell list of the same frequency, different frequency or different system to the user terminal according to the set time. After receiving the neighbor CELL list of the co-frequency, inter-frequency or inter-system configured by the network, the user terminal in the CELL _ FACH state and the CELL _ DCH state needs to perform co-frequency, inter-frequency or inter-system measurement at the specified time.
Sometimes, the user terminal does not need to measure at all, but can measure after receiving the neighbor cell list, so that the user terminal can perform a lot of unnecessary measurements, the user terminal needs to occupy a lot of resources when measuring, and the occupied resources cannot be used for transmission, thereby causing resource waste.
In summary, at present, after receiving the cell list configured by the network, the ue performs measurement at the specified time, which causes resource waste and reduces resource utilization.

Detailed Description
After the user terminal determines that the quality of the received signal meets the measurement condition, the user terminal determines the time for measurement according to the received measurement time parameter information from the RNC, and measures according to the received neighbor cell list from the RNC when the determined measurement time is up. The user terminal starts to measure after meeting the measuring condition, thereby reducing the times of useless measurement, saving resources and improving the utilization rate of the resources.
In the conventional CELL _ FACH state, since the terminal needs to monitor a Forward Access Channel (FACH), the FACH is mapped to a Physical Channel SCCPCH (secondary common Control Physical Channel), and the SCCPCH is located at TS 0. That is, in the conventional CELL _ FACH state, the ue needs to continuously listen to the SCCPCH channel of TS0 time slot. If the user terminal needs to measure, it must jump to another frequency point at TS0 to monitor the PCCPCH of the neighboring cell. If the base station uses the FACH channel to send data to the user terminal, and the user terminal jumps to another frequency point to monitor the PCCPCH of the neighboring cell at the moment, the SCCPCH cannot be monitored by the user terminal, and subsequent data loss is caused. For this case, a formula is defined for calculating the measurement opportunity:
SFN div N ═ C _ RNTI mod M _ REP + N ═ M _ REP (formula one)
Wherein SFN represents the number of radio frames; n represents a maximum TTI (Transmission time interval) length (in units of radio frames) of the FACH; C-RNTI is the identification of the terminal; m _ REP is a measurement period, the value of which is configured by the RNC; n is an integer and takes a value of 0, 1, 2. These parameters are configured to both the base station and the user terminal. For the SFN satisfying the above formula, the ue performs measurement, and the bs does not transmit data to the ue at the corresponding SFN. The user terminal and the base station start the calculation and measurement opportunity formula after receiving the configured parameters, thereby avoiding the occurrence of the data loss problem.
In the CELL _ DCH or enhanced CELL _ FACH state, since the PCCPCH channel only exists on TS0, if the ue wants to perform inter-frequency measurement, it must jump to another frequency point at TS0 to monitor the PCCPCH of the neighboring CELL. For a system using TS0, for example, an HS-SCCH (High-Speed shared control channel) channel is configured at TS0, if the base station schedules the user terminal at TS0, and the user terminal jumps to another frequency point to monitor the PCCPCH of the neighboring cell, the user terminal may not monitor the HS-SCCH, and subsequent data loss may be caused. For this case, a formula is defined for calculating the measurement opportunity:
SFN ═ H-RNTI mod M _ REP + n × M _ REP (formula two)
Wherein SFN represents the number of radio frames; H-RNTI is the identification of the terminal; m _ REP is a measurement period, the value of which is configured by the RNC; n is an integer and takes a value of 0, 1, 2. These parameters are configured to both the base station and the user terminal. For SFN satisfying the above formula, the user terminal performs measurement, and the base station does not schedule the user terminal at the corresponding SFN. The user terminal and the base station start the calculation and measurement opportunity formula after receiving the configured parameters, thereby avoiding the occurrence of the data loss problem.
It should be noted that the formulas used by the ue and the base station to calculate the measurement time in the embodiment of the present invention are not limited to the above two formulas, and any other formulas capable of calculating the measurement time are all used in the embodiment of the present invention.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, a system for performing measurement according to an embodiment of the present invention includes: RNC10 and user terminal 20.
And the RNC10 is used for sending the measurement time parameter and the neighbor cell list.
The ue 20 is configured to determine a measurement time according to the received measurement time parameter information after determining that the received signal quality satisfies the measurement condition, and perform measurement according to the received neighbor cell list when the determined measurement time arrives.
Wherein, if the received signal quality is characterized by the signal strength of the cell where the ue is located (i.e. the received signal quality can be determined according to the signal strength of the cell where the ue is located), the measurement condition includes:
the signal intensity of the cell where the user terminal is located is lower than a first set threshold value, and the duration time is longer than the first threshold value.
Specifically, the first set threshold value and the first threshold value may be set as needed. An extreme way is to set the first threshold to 0, so that it is determined that the received signal quality satisfies the measurement condition as long as the signal strength of the cell in which the ue is located is lower than the first set threshold.
In a specific implementation process, the Signal strength of the cell in which the ue is located may be a Received Power of a Primary Common Control Physical Channel (PCCPCH) of the cell in which the ue is located, that is, a Received Signal Code Power (RSCP).
It should be noted that, in the embodiment of the present invention, the signal strength of the cell in which the ue is located is not limited to the received power of the PCCPCH, and the received powers of other channels are also applicable to the embodiment of the present invention.
If the received signal quality is characterized by the path loss of the user terminal (i.e. the received signal quality can be determined from the path loss of the user terminal), the measurement conditions include:
the path loss of the user terminal is higher than a second set threshold value, and the duration is longer than the set second threshold value.
Specifically, the second set threshold value and the second threshold value may be set as needed. One extreme way is to set the second threshold to 0, so that it is determined that the received signal quality meets the measurement condition as long as the path loss of the subscriber terminal is higher than the second set threshold.
In the implementation, the path loss is the difference between the actual received power and the actual transmitted power of the ue.
The formula three can be used to calculate:
srxlev ═ Qrxlevmeas-Qrxlevmin-Pcomnpenpenation (equation three)
Wherein, Qrxlevmeas represents the actual receiving power of the user terminal; qrxlevmin indicates that the cell requires the minimum received power (informed by the broadcast); pcompensation is the larger of UE _ TXPWR _ MAX _ RACH-P _ MAX and 0, UE _ TXPWR _ MAX _ RACH representing the maximum transmit power allowed on the RACH channel, and P _ MAX representing the maximum output power of the user terminal.
It should be noted that the method for calculating the path loss in the embodiment of the present invention is not limited to the formula three, and other formulas capable of calculating the path loss are all used in the embodiment of the present invention.
There are two ways for the RNC10 to send the measurement time parameter and the neighbor cell list to the user terminal 20.
In the first mode, the user terminal 20 notifies the RNC10 of sending the measurement time parameter and the neighbor cell list.
After the user terminal 20 determines that the received signal quality satisfies the measurement condition, the RNC10 transmits measurement time parameter information and a neighbor cell list to the user terminal 20.
In order for the base station 30 to be able to not schedule the user terminal 20 or send data to the user terminal 20 at the time the user terminal 20 is making measurements, the RNC10 also needs to send measurement time parameter information to the base station 30.
In a specific implementation, after receiving the acquiring message, the RNC10 sends the measurement time parameter information to the base station 30 before the ue 20 determines the time for performing the measurement.
The RNC10 may send the measurement time parameter information to the base station 30 earlier than the time to return the measurement time parameter information and the neighbor cell list to the user terminal 20; or later than the time of returning the measurement time parameter information and the neighbor cell list to the user terminal 20; the measurement time parameter information may be transmitted to the base station 30 while returning the measurement time parameter information and the time of the neighbor cell list to the user terminal 20.
Accordingly, the ue 20 and the bs 30 determine the measurement time according to the received measurement time parameter information.
In a specific implementation, the base station 30 may determine whether to use formula one or formula two according to the parameters configured by the RNC 10.
The acquiring message sent by the ue 20 to the RNC10 may be RRC (Radio resource control) signaling or special MAC PDU (MAC Packet Data Unit) format message.
It should be noted that the acquiring message in the embodiment of the present invention is not limited to the above two messages, and other messages capable of notifying the RNC10 that the measurement time parameter information and the neighbor cell list need to be acquired are all applicable to the embodiment of the present invention.
In the second mode, the RNC10 sends the measurement time parameter and the neighbor cell list directly to the user terminal 20.
The RNC10 sends the measurement time parameter and the neighbor cell list to the user terminal 20 before the user terminal 20 determines that the received signal quality satisfies the measurement condition.
In order for the base station 30 to be able to not schedule the user terminal 20 or send data to the user terminal 20 at the time the user terminal 20 is making measurements, the RNC10 also needs to send measurement time parameter information to the base station 30.
In particular implementations, the RNC10 may also need to send measurement time parameter information to the base station 30 before determining that the received signal quality satisfies the measurement condition.
The RNC10 may send the measurement time parameter information to the base station 30 earlier than the time to return the measurement time parameter information and the neighbor cell list to the user terminal 20; or later than the time of returning the measurement time parameter information and the neighbor cell list to the user terminal 20; the measurement time parameter information may be transmitted to the base station 30 while returning the measurement time parameter information and the time of the neighbor cell list to the user terminal 20.
Correspondingly, after receiving the measurement time parameter information, the user terminal 20 and the base station 30 buffer the measurement time parameter information;
after determining that the received signal quality meets the measurement condition, the user terminal sends notification information to the base station 30, so as to notify the base station 10 that the user terminal 30 starts to perform measurement;
correspondingly, after receiving the notification message, the base station 30 determines the measurement time of the user terminal 20 according to the cached measurement time parameter information; and after the user terminal 20 sends the notification information, the measurement time is determined according to the cached measurement time parameter information.
In consideration of the reliability of the control channel, a preferred method is that the ue 20 repeatedly sends the notification message to the bs 30, and determines the measurement time according to the buffered measurement time parameter information after the number of times of repeated sending reaches a set number; in another way, the base station 30 returns a response message to the ue 20 after receiving the notification message, and the ue 20 determines the measurement time according to the buffered measurement time parameter information after receiving the response message.
Wherein the base station 30 needs to determine what state the user terminal 20 is currently in before determining the measurement time of the user terminal 20:
if the ue 20 is in the conventional CELL _ FACH state, the ue 20 and the base station 30 determine the measurement time according to the formula one;
if the user terminal 20 is in CELL _ DCH or enhanced CELL _ FACH state, the user terminal 20 and the base station 30 determine the measurement time according to formula two.
In a specific implementation, the ue 20 may notify the base station of the physical layer signaling as a notification message. This physical layer signaling may be a special E-RUCCH (E-DCH Random access uplink control Channel, Random access uplink control Channel for enhanced dedicated transport channels).
For example, the notification information includes TEBS (Total E-DCH Buffer Status, Total Buffer amount of the enhanced dedicated transport channel) and HLBS (high priority Logical channel Buffer Status, Buffer occupancy of the Highest priority Logical channel), where the TEBS is set to 0 and the HLBS is set to be greater than 0 (such as 1111). Since it is practically impossible for the HLBS to be greater than 0 after the TEBS is set to 0, the base station 30 knows that it is a notification message after receiving it.
It should be noted that the notification message according to the embodiment of the present invention is not limited to the above form, and other messages capable of notifying the base station 30 are applicable to the embodiment of the present invention.
In the first and second modes, the RNC10 may also place the measurement time parameter information in an NBAP (node b ap Protocol) signaling or FP (Frame Protocol) Frame and send the measurement time parameter information to the base station 30.
It should be noted that the embodiment of the present invention is not limited to the above-mentioned manner of transmitting the measurement time parameter information to the base station 30, and any other manner capable of transmitting the measurement time parameter information to the base station 30 is used as the embodiment of the present invention.
As shown in fig. 2, the user terminal according to the embodiment of the present invention includes: a receiving module 200, a time determining module 210 and a measuring module 220.
A receiving module 200, configured to receive measurement time parameter information and a neighbor cell list from an RNC.
A time determining module 210, configured to determine, according to the received measurement time parameter information, a time for performing measurement after determining that the received signal quality satisfies the measurement condition;
a measuring module 220, configured to perform measurement according to the received neighbor cell list when the determined measurement time arrives.
Wherein, if the received signal quality is characterized by the signal strength of the cell where the user terminal is located, the measurement condition includes:
the signal intensity of the cell where the user terminal is located is lower than a first set threshold value, and the duration time is longer than the first threshold value.
In a specific implementation process, the signal strength of the cell in which the ue is located may be the received power of the PCCPCH, i.e., the RSCP, of the cell in which the ue is located.
It should be noted that, in the embodiment of the present invention, the signal strength of the cell in which the ue is located is not limited to the received power of the PCCPCH, and the received powers of other channels are also applicable to the embodiment of the present invention.
If the received signal quality is characterized by a path loss for the user terminal, the measurement conditions include:
the path loss of the user terminal is higher than a second set threshold value, and the duration is longer than the set second threshold value.
In the implementation, the path loss is the difference between the actual received power and the actual transmitted power of the ue. Formula three may be used for the calculation.
It should be noted that the method for calculating the path loss in the embodiment of the present invention is not limited to the formula three, and other formulas capable of calculating the path loss are all used in the embodiment of the present invention.
There are two ways for the receiving module 200 to receive the measurement time parameter and the neighbor cell list.
The first method is as follows: after determining that the received signal quality meets the measurement condition and before determining the measurement time, the time determination module 200 sends an acquisition message to the RNC;
accordingly, the receiving module 200 receives the measurement time parameter and the neighbor cell list from the RNC after determining that the received signal quality satisfies the measurement condition.
The acquiring message sent by the receiving module 200 to the RNC may be RRC signaling or a special MAC PDU format message.
It should be noted that the acquisition message in the embodiment of the present invention is not limited to the above two messages, and other messages capable of notifying the RNC that the measurement time parameter information and the neighbor cell list need to be acquired are all applicable to the embodiment of the present invention.
In the second mode, before determining that the quality of the received signal meets the measurement condition, the receiving module 200 receives the measurement time parameter and the neighbor cell list from the RNC;
accordingly, the time determination module 200 sends notification information to the base station after determining that the received signal quality satisfies the measurement condition, for notifying the base station that the ue starts to perform measurement.
In consideration of the reliability of the control channel, a preferred mode is that the time determination module 200 repeatedly transmits the notification information to the base station, and determines the measurement time according to the cached measurement time parameter information after the number of times of repeated transmission reaches a set number; in still another way, the time determination module 200 determines the measurement time according to the buffered measurement time parameter information after receiving the response message from the base station.
In a specific implementation, the time determination module 200 may notify the base station of the physical layer signaling as a notification message. This physical layer signaling may be a special E-RUCCH.
For example, the notification information includes TEBS and HLBS, where TEBS is set to 0 and HLBS is set to greater than 0 (e.g., 1111).
It should be noted that the notification message according to the embodiment of the present invention is not limited to the above form, and other messages capable of notifying the base station are applicable to the embodiment of the present invention.
As shown in fig. 3, a first RNC according to an embodiment of the present invention includes: a first processing module 100 and an information sending module 110.
A first processing module 100, configured to receive an acquisition message from a ue, where the acquisition message is sent by the ue after determining that the received signal quality meets a measurement condition;
an information sending module 110, configured to send measurement time parameter information and a neighbor cell list to the user equipment after receiving the obtaining message, and send a measurement time parameter to the base station.
The information sending module 110 may send the measurement time parameter information to the base station earlier than the time for returning the measurement time parameter information and the neighbor cell list to the user terminal; or later than the time for returning the measurement time parameter information and the neighbor cell list to the user terminal (the measurement time cannot be determined later than the user terminal); the measurement time parameter information and the time of the neighbor cell list may also be sent to the base station while returning the measurement time parameter information to the user terminal.
As shown in fig. 4, the base station according to the embodiment of the present invention includes: a second processing module 300 and a determination module 310.
A second processing module 300, configured to receive the measurement time parameter from the RNC.

In a specific implementation process, the second processing module 300 may buffer the measurement time parameter after receiving the measurement time parameter; the determining module 310 extracts the measurement time parameter cached by the second processing module 300 after receiving the notification message from the ue, and determines the time for the ue to perform measurement according to the measurement time parameter.
As shown in fig. 5, a first method for performing measurement according to an embodiment of the present invention includes the following steps:
Wherein, if the received signal quality is characterized by the signal strength of the cell where the user terminal is located, the measurement condition includes:
the signal intensity of the cell where the user terminal is located is lower than a first set threshold value, and the duration time is longer than the first threshold value.
Specifically, the first set threshold value and the first threshold value may be set as needed. An extreme way is to set the first threshold to 0, so that it is determined that the received signal quality satisfies the measurement condition as long as the signal strength of the cell in which the ue is located is lower than the first set threshold.
In a specific implementation process, the signal strength of the cell in which the ue is located may be the received power of the PCCPCH, i.e., the RSCP, of the cell in which the ue is located.
It should be noted that, in the embodiment of the present invention, the signal strength of the cell in which the ue is located is not limited to the received power of the PCCPCH, and the received powers of other channels are also applicable to the embodiment of the present invention.
If the received signal quality is characterized by a path loss for the user terminal, the measurement conditions include:
the path loss of the user terminal is higher than a second set threshold value, and the duration is longer than the set second threshold value.
Specifically, the second set threshold value and the second threshold value may be set as needed. One extreme way is to set the second threshold to 0, so that it is determined that the received signal quality meets the measurement condition as long as the path loss of the subscriber terminal is higher than the second set threshold.
In the implementation, the path loss is the difference between the actual received power and the actual transmitted power of the ue. Formula three may be used for the calculation.
It should be noted that the method for calculating the path loss in the embodiment of the present invention is not limited to the formula three, and other formulas capable of calculating the path loss are all used in the embodiment of the present invention.
There are two ways for the RNC to send the measurement time parameter and the neighbor cell list to the user terminal.
In the first mode, the user terminal informs the RNC to send the measurement time parameter and the neighbor cell list.
Step 501 may further include:
step a501, the user terminal determines that the quality of the received signal meets the measuring condition, and sends an acquisition message to the RNC
Step b501, after receiving the acquisition message, the RNC returns the measurement time parameter information and the neighbor cell list to the user terminal;
step c501, the user terminal determines the time for measurement according to the received time parameter information.
In order for the base station (i.e. the base station of the cell in which the ue is located) to be able to not schedule the ue or send data to the ue at the time when the ue performs the measurement, the RNC further needs to send measurement time parameter information to the base station.
In step b501, after receiving the acquisition message, the RNC sends measurement time parameter information to the base station.
The time for RNC to send the measurement time parameter information to the base station can be earlier than the time for returning the measurement time parameter information and the neighbor cell list to the user terminal; or later than the time for returning the measurement time parameter information and the neighbor cell list to the user terminal; the measurement time parameter information and the time of the neighbor cell list may also be sent to the base station while returning the measurement time parameter information to the user terminal.
Correspondingly, the user terminal and the base station determine the measuring time according to the received measuring time parameter information.
In the specific implementation process, the base station may determine whether to use the formula one or the formula two according to the parameter configured by the RNC.
The acquisition message sent by the user terminal to the RNC may be RRC signaling or a special MAC PDU format message.
It should be noted that the acquisition message in the embodiment of the present invention is not limited to the above two messages, and other messages capable of notifying the RNC that the measurement time parameter information and the neighbor cell list need to be acquired are all applicable to the embodiment of the present invention.
And in the second mode, the RNC directly sends the measurement time parameter and the neighbor cell list to the user terminal.
Step 501 may further include:
step a500, RNC sends measurement time parameter and adjacent cell list to user terminal;
step b500, the user terminal receives the measurement time parameter and the neighbor cell list.
In order for the base station not to schedule the ue or send data to the ue at the time when the ue performs measurement, the RNC further needs to send measurement time parameter information to the base station.
In step a500, the RNC further needs to send measurement time parameter information to the base station.
The time for RNC to send the measurement time parameter information to the base station can be earlier than the time for returning the measurement time parameter information and the neighbor cell list to the user terminal; or later than the time for returning the measurement time parameter information and the neighbor cell list to the user terminal; the measurement time parameter information and the time of the neighbor cell list may also be sent to the base station while returning the measurement time parameter information to the user terminal.
Correspondingly, after receiving the measurement time parameter information, the user terminal and the base station buffer the measurement time parameter information;
in step 501, after determining that the received signal quality meets the measurement condition, the ue sends notification information to the base station to notify the base station that the ue starts to perform measurement;
correspondingly, after receiving the notification message, the base station determines the measurement time of the user terminal according to the cached measurement time parameter information; and after the user terminal sends the notification information, determining the measurement time according to the cached measurement time parameter information.
In consideration of the reliability of the control channel, a preferred mode is that the user terminal repeatedly sends notification information to the base station, and determines the measurement time according to the cached measurement time parameter information after the number of times of repeated sending reaches a set number; in another mode, the base station returns a response message to the ue after receiving the notification message, and the ue determines the measurement time according to the cached measurement time parameter information after receiving the response message.
Wherein, the base station needs to determine what state the user terminal is currently in before determining the measurement time of the user terminal:
if the user terminal is in the traditional CELL _ FACH state, the user terminal and the base station determine the measurement time according to a formula I;
and if the user terminal is in a CELL _ DCH state or an enhanced CELL _ FACH state, the user terminal and the base station determine the measurement time according to a formula II.
In the implementation process, the ue may notify the base station of the physical layer signaling as a notification message. This physical layer signaling may be a special E-RUCCH.
For example, the notification information includes TEBS and HLBS, where TEBS is set to 0 and HLBS is set to greater than 0 (e.g., 1111).
It should be noted that the notification message according to the embodiment of the present invention is not limited to the above form, and other messages capable of notifying the base station are applicable to the embodiment of the present invention.
In the first and second modes, the RNC may also place the measurement time parameter information in NBAP signaling or FP frame and send it to the base station.
It should be noted that the embodiment of the present invention is not limited to the above-mentioned manner of sending the measurement time parameter information to the base station, and any other manner capable of sending the measurement time parameter information to the base station is used in the embodiment of the present invention.
