Description
Technical Field
The invention relates to the technical field of communication, in particular to a cell measurement method and a user terminal.
Background
A dual connection technology is introduced into Long Term Evolution (LTE) Release 12, so that a User Equipment (UE) can simultaneously utilize resources of two LTE base stations to perform data transmission, which not only can improve data throughput rate, but also can improve mobility.
For a UE configured with dual connectivity, a Master base station (Master eNB, MeNB) connected to the UE is responsible for transmission of Radio Resource Control (RRC) signaling, and a Secondary base station (Secondary eNB, SeNB) is responsible for configuration of a Secondary Cell Group (SCG). The SeNB only transmits data, and the secondary cell group configured by the SeNB needs to be sent to the UE through the MeNB by RRC signaling. Both MeNB and SeNB may configure multiple serving cells to the UE.
With the development of wireless technology, 3GPP will introduce New Radio access technology (NR), which is called as a fifth generation mobile communication technology, i.e. 5G, to meet the requirement of larger data volume and smaller transmission delay. Operators have widely deployed LTE networks, so in order to fully utilize existing LTE networks, at the early stage of NR network deployment, an NR network may not be deployed independently, and needs to cooperate closely with the LTE network (light Interworking), and an LTE-NR dual connectivity technology may be used so that a UE can use both the LTE network and the NR network for data transmission.
In LTE-NR dual connectivity, the NR base station as the SeNB may have RRC signaling interaction with the UE, configure NR measurements for the UE, and receive measurement reports directly from the UE, so the UE may be configured by the MeNB and the SeNB at the same time to measure certain NR frequencies.
When the UE receives the measurement configuration messages sent by the MeNB and the SeNB to the cells with the same frequency, the UE respectively performs measurement and respectively reports a measurement report, which wastes not only the power consumption of the UE but also precious wireless signaling resources.

Detailed Description
In 5G, it is assumed that a plurality of NR base stations are deployed within a coverage area of a cell under the jurisdiction of the LTE base station, and if the UE first accesses the LTE network, the LTE and NR dual connectivity is configured in order to perform subsequent configuration (that is, the NR base station is configured as the SeNB, and the LTE base station needs to configure measurement of the NR neighboring cell by the UE.
In the specific process of configuring the dual connectivity, the LTE base station may send a dual connectivity configuration request to the NR base station, after the NR base station configures the wireless parameters for the UE, the NR base station returns a dual connectivity configuration response message to the LTE base station, the LTE base station sends the wireless parameters configured at the NR side to the UE, and the UE accesses the NR cell according to the wireless parameters configured at the NR side to successfully establish the dual connectivity.
Referring to fig. 1, for a UE configured with LTE-NR dual connectivity, in order to maintain the configuration of serving cells in SCG, such as increasing the number of serving cells in SCG or decreasing the number of serving cells in SCG, and to implement the requirement for change of SeNB, the NR base station eNB2 as SeNB may have RRC signaling interaction with the UE, and the NR base station eNB2 needs to configure the UE to measure cells of certain NR frequencies and receive measurement reports directly from the UE. Thus the UE may be simultaneously configured by base station eNB1 of LTE and NR base station eNB2 to measure cells on certain NR frequencies.
Currently, once receiving a measurement configuration message sent by a network, a UE needs to perform measurement according to the measurement configuration message, and report a measurement report to a network side when a reporting condition is met. Therefore, for the UE configured with LTE-NR dual connectivity, once receiving the measurement configuration messages sent by the MeNB and the SeNB, the UE needs to perform cell measurement according to the measurement configuration messages sent by the MeNB and the SeNB, and then report measurement reports to the MeNB and the SeNB, which wastes not only power consumption of the UE but also valuable radio signaling resources.
In view of the above problems, embodiments of the present invention provide a cell measurement method, where when measurement configuration information for measuring a cell of the same frequency exists in measurement configuration messages sent by a primary base station and a secondary base station, the method selects corresponding measurement configuration information sent by the primary base station or the secondary base station according to a preset measurement condition to measure the cell of the same frequency, and sends a measurement report to a corresponding base station.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 2, an embodiment of the present invention provides a cell measurement method, where the method is applied to a terminal.
Specifically, the method may comprise the steps of:
The primary base station and the secondary base station respectively correspond to different wireless access networks, the wireless access network may be a wireless access network implemented by a public mobile communication network, such as 5G, 4G, 3G, or General Packet Radio Service (GPRS), or may also be a wireless local area network (WiFi), and the like, and the wireless access network is not particularly limited as long as the network uses a wireless electromagnetic wave as a transmission medium.
For example, the primary base station may correspond to an LTE network, and the secondary base station may correspond to an NR network, where the primary base station is an LTE base station and the secondary base station is an NR base station. Of course, the main base station may also correspond to an NR network, and the secondary base station corresponds to an LTE network, where the main base station is an NR base station, and the secondary base station is an LTE base station.
In a specific implementation, after the UE establishes the dual connectivity, it may perform signaling interaction with the primary base station and the secondary base station. The primary base station and the secondary base station may respectively configure a cell for measuring some frequencies for the UE, and the cell corresponding to the frequency may be a cell of a wireless access network where the secondary base station is located, or may be a cell of a wireless access network where the primary base station is located. The frequencies of the cells configured by the primary base station and the secondary base station may be completely the same or partially the same, or may be completely different. In the measurement configuration, only the frequency information to be measured may be included, and the cell information on the frequency is not included, and after receiving the measurement configuration, the UE may measure the cell on the frequency by detecting a synchronization signal or a cell-specific reference signal.
And step 22, when the measurement configuration information for measuring the cell of the same frequency exists in the measurement configuration messages sent by the main base station and the secondary base station, selecting the corresponding measurement configuration information sent by the main base station or the secondary base station according to preset measurement condition information to measure the cell of the same frequency, and sending a measurement report to the selected base station.
In specific implementation, the measurement configuration message sent by the base station usually includes a plurality of measurement identification information, and the terminal can obtain the measurement requirement information of the terminal according to the measurement configuration message and some other wireless configuration parameters of the terminal, for example, the measurement requirement information that the terminal needs to meet for measuring the same frequency, different frequency, and different system is specially formulated in the existing LTE protocol TS 36.133. Each measurement identification information includes frequency information of a cell to be measured and corresponding measurement report reporting condition information. The terminal measurement requirement information, that is, the condition information that needs to be satisfied when the UE performs cell measurement of a corresponding frequency, for example, the measurement requirement that the UE needs to satisfy measurement of a co-frequency cell in certain scenarios is that 8 co-frequency neighboring cells can be measured within 200ms as specified in LTE.
In an embodiment of the present invention, the preset measurement condition information may be measurement reporting condition information corresponding to the cells of the same frequency in measurement configuration messages sent by the primary base station and the secondary base station.
In a specific implementation, the measurement reporting condition information may include: and reporting the measurement report according to a preset period. That is, the UE may periodically report a measurement report when performing cell measurement of a corresponding frequency.
At this time, when the measurement configuration information for measuring the cell of the same frequency exists in the measurement configuration messages sent by the primary base station and the secondary base station, the UE may select the corresponding measurement configuration information to measure the cell of the same frequency according to a corresponding measurement report reporting period in the measurement configuration information sent by the primary base station and the secondary base station, that is, a measurement report reporting period set in the measurement reporting condition information. The UE may select the measurement configuration information with a shorter measurement report reporting period to measure the cell of the same frequency, or may select the measurement configuration information with a longer measurement report reporting period to measure the cell of the same frequency, which is not limited specifically.
In a specific implementation, the measurement reporting condition information may include: and reporting the measurement report when the preset event is met. That is, the UE may report the measurement report event-triggered when performing cell measurement of the corresponding frequency.
At this time, when the measurement configuration messages sent by the primary base station and the secondary base station have measurement configuration information for measuring the cells of the same frequency, and the corresponding measurement report reporting condition information both satisfy the same preset event, the UE may select the corresponding measurement configuration information to measure the cells of the same frequency according to the corresponding trigger thresholds in the measurement configuration information sent by the primary base station and the secondary base station, that is, the event trigger threshold set in the measurement reporting condition information. The UE may select the measurement configuration information with a lower trigger threshold to measure the cell of the same frequency, or may select the measurement configuration information with a higher trigger threshold to measure the cell of the same frequency, which is not limited specifically.
In a specific implementation, the preset event may include a plurality of types, and is not particularly limited.
For example, the preset event may be: and the duration of the signal characteristic value of the adjacent region being higher than the first preset value is longer than a preset first time length. The signal characteristic value may be signal quality or signal strength, that is, signal quality or signal strength of a neighboring cell measured by the terminal. In this case, the UE may select the measurement configuration information with the shorter first time length from the measurement configuration information transmitted by the primary base station and the secondary base station to measure the cell of the same frequency, or may select the measurement configuration information with the longer first time length to measure the cell of the same frequency.
For another example, the preset event may also be: and the duration that the signal characteristic value of the adjacent cell is higher than the characteristic value of the serving cell by a second preset value is longer than a preset second time length. At this time, the UE may select the measurement configuration information with the shorter second duration from the measurement configuration information sent by the primary base station and the secondary base station to measure the cell of the same frequency, or may select the measurement configuration information with the longer second duration to measure the cell of the same frequency.
For another example, when the corresponding first time lengths in the measurement configuration information sent by the primary base station and the secondary base station are the same, the preset measurement condition information may also be: the signal characteristic value of the adjacent area is higher than a first preset value. At this time, the UE may select the measurement configuration information with a smaller first preset value from the measurement configuration information sent by the primary base station and the secondary base station to measure the cell of the same frequency, or may select the measurement configuration information with a larger first preset value to measure the cell of the same frequency.
For another example, when the second time lengths corresponding to the measurement configuration information sent by the primary base station and the secondary base station are the same, the preset measurement condition information may also be: the signal characteristic value of the adjacent cell is higher than the characteristic value of the serving cell by a second preset value. At this time, the UE may select the measurement configuration information with a smaller second preset value from the measurement configuration information sent by the primary base station and the secondary base station to measure the cell of the same frequency, or may select the measurement configuration information with a larger second preset value to measure the cell of the same frequency.
In another embodiment of the present invention, the preset measurement condition information may be measurement requirement information that the terminal needs to meet for measuring the cell of the same frequency. The terminal may determine measurement requirement information that needs to be satisfied for measuring the cells of the same frequency according to the measurement configuration messages sent by the primary base station and the secondary base station. The terminal measurement requirement may not be included in the measurement configuration message, and the terminal may determine the corresponding measurement requirement information according to the measurement configuration message and the corresponding protocol.
The measurement requirement information relates to a frequency to be measured, and a Discontinuous Reception (DRX) cycle length configured by the UE. At this time, the UE may select measurement configuration information with a stricter measurement requirement to measure the cell of the same frequency according to measurement requirement information corresponding to the measurement configuration information sent by the primary base station and the secondary base station, or select measurement configuration information with a looser measurement requirement to measure the cell of the same frequency.
For example, in the measurement configuration information sent by the primary base station, the corresponding measurement requirement information is: when measuring a cell with a frequency of F1, the UE needs to measure 8 neighbor cells within 400 ms. In the measurement configuration information sent by the secondary base station, the corresponding measurement requirement information is as follows: when measuring a cell with a frequency of F1, the UE needs to measure 8 neighbor cells within 200 ms. In this case, the UE may select the measurement configuration information transmitted by the secondary base station to measure the cell with the frequency F1, or may select the measurement configuration information transmitted by the primary base station to measure the cell with the frequency F1.
When the corresponding measurement requirement information in the measurement configuration information sent by the primary base station and the secondary base station is the same, the UE may randomly select to execute the measurement configuration information of one of the base stations to measure the cell of the same frequency.
In another embodiment of the present invention, when the measurement configuration information sent by the primary base station or the secondary base station is selected according to the preset measurement condition information to measure the cell of the same frequency, the UE may select the measurement configuration information sent by the base station of the same radio access network as the cell of the same frequency to perform measurement, for example, when the same frequency is an NR frequency, the UE may select the measurement configuration information sent by the NR base station to measure the frequency, and when the same frequency is an LTE frequency, the UE may select the measurement configuration information sent by the LTE base station to measure the frequency.
In an implementation, the measurement configuration information sent by the primary base station and the secondary base station may be configured with corresponding measurement configuration information for a plurality of cells of the same frequency at the same time. At this time, the UE may measure the cells of the corresponding frequency according to the preset measurement condition information and the measurement configuration information sent by different base stations.
For example, the primary base station and the secondary base station may respectively configure the UE with cells measuring certain NR frequencies, where the primary base station configures the UE with cells measuring NR frequencies F1, F2, and F3, and the secondary base station configures the UE with cells measuring NR frequencies F1 and F2. After receiving the signaling configuration messages sent by the primary base station and the secondary base station, the UE learns that the primary base station and the secondary base station are both configured with the measurement configuration information for the cells with the frequencies F1 and F2. At this time, the UE may measure the cell of frequency F1 according to the measurement configuration information transmitted by the primary base station, and measure the cell of frequency F2 according to the measurement configuration information transmitted by the secondary base station.
In a specific implementation, when the measurement configuration information transmitted by the main base station is selected to measure the cell of the same frequency, the measurement report related to the cell of the same frequency is transmitted to the main base station. And when the measurement configuration information sent by the secondary base station is selected to measure the cell with the same frequency, sending a measurement report related to the cell with the same frequency to the secondary base station.
In a specific implementation, a measurement report reported by a UE needs to meet a specification of a network protocol in which a corresponding base station is located, and unselected base stations generally cannot understand the measurement report reported by the UE. Therefore, in order to enable the unselected base stations to obtain the cell measurement result of the same frequency in time, in an embodiment of the present invention, the measurement report may include: and the first indication information is suitable for indicating the corresponding base station to forward the measurement result of the cell with the same frequency to the unselected base station in the main base station and the auxiliary base station. And the corresponding base station forwards the measurement result to the unselected base station through an interface between the corresponding base station and the unselected base station, so that the unselected base station can correctly analyze the measurement result of the cell with the same frequency in the measurement report reported by the UE.
For example, when the LTE base station and the NR base station have measurement configuration information for the cells of frequencies F1 and F2, the UE measures the cell of frequency F1 according to the measurement configuration information transmitted by the LTE base station, and measures the cell of frequency F2 according to the measurement configuration information transmitted by the NR base station. And after the measurement reporting conditions are met, the UE reports the cell measurement result of the frequency F1 to the LTE base station and reports the cell measurement result of the frequency F2 to the NR base station.
The cell measurement result of the frequency F1 reported by the UE to the LTE base station needs to meet the specification of the LTE protocol, and the NR base station generally cannot understand the measurement report reported by the UE using the LTE protocol. By setting the first indication information in the measurement report, the LTE base station is instructed to forward the measurement result to the NR base station through the interface with the NR base station, so that the NR base station can correctly resolve the cell measurement result of the frequency F1. Likewise, for the cell measurement result of frequency F2, the NR base station forwards the measurement result to the LTE base station through an interface with the LTE base station, so that the LTE base station can correctly resolve the cell measurement result of frequency F2.
Referring to fig. 3, another cell measurement method is provided in an embodiment of the present invention, and is applied to a terminal.
Specifically, the method may comprise the steps of:
And step 32, when the measurement configuration information for measuring the cell of the same frequency exists in the measurement configuration messages sent by the main base station and the secondary base station, selecting the corresponding measurement configuration information sent by the main base station or the secondary base station according to the preset measurement condition information to measure the cell of the same frequency, and sending a measurement report to the selected base station.
For the steps 31 and 32, reference may be made to the above description of the steps 21 and 22, which is not repeated herein.
And step 33, sending instruction information for suspending measurement of the cell of the same frequency to unselected base stations of the main base station and the auxiliary base station.
In a specific implementation, the indication information for the suspension to measure the cell of the same frequency includes a measurement frequency (or a measurement identifier) to be suspended. The suspended frequency may be only one frequency, two frequencies, or more than two frequencies, and is not limited specifically. In other words, the indication information for performing measurement on the cell of the same frequency through the suspension may indicate that the UE suspends the cell measurement of one frequency, or may indicate that the UE suspends the cell measurement of two or more frequencies.
In a specific implementation, when the UE determines to execute the measurement configuration information of one of the primary base station and the secondary base station and measure the cell of the same frequency, the UE may send, to a base station on the other side, that is, an unselected base station, indication information for suspending measurement of the cell of the same frequency, that is, temporarily suspending measurement configured for the unselected base station, so that the unselected base station may know that the current UE does not actively report the measurement result of the cell of the same frequency to the unselected base station. But the UE may continue to store the measurement configuration information sent by the unselected base stations, and once the UE disconnects the dual connectivity, the measurement configured by the unselected base stations may be resumed immediately.
As can be seen from the above, in the cell measurement method in the embodiment of the present invention, when measurement configuration information for measuring a cell of the same frequency exists in measurement configuration messages sent by a primary base station and a secondary base station, the corresponding measurement configuration information sent by the primary base station or the secondary base station is selected according to preset measurement condition information to measure the cell of the same frequency, which not only can reduce power consumption of a UE, but also can save wireless signaling resources.
In view of the above problems, embodiments of the present invention provide a cell measurement method, where, when receiving suspension measurement indication information, a user terminal that has established connections with a primary base station and a secondary base station respectively suspends measurements of a frequency cell configured by a corresponding base station, and compared with performing measurements respectively and reporting measurement reports respectively, the method of the present invention not only can reduce power consumption of a UE, but also can save wireless signaling resources.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 4, another cell measurement method is provided in an embodiment of the present invention, and the method is applicable to a user equipment that has established connections with a primary base station and a secondary base station, respectively.
Specifically, the method may comprise the steps of:
In a specific implementation, the suspension measurement indication information may be transmitted by the primary base station, or may be transmitted by the secondary base station, which is not limited specifically. The primary base station and the secondary base station respectively correspond to different wireless access networks, the wireless access networks may be wireless access networks implemented by public mobile communication networks such as 5G, 4G, 3G, GPRS, or the like, or WiFi, and the like, and the wireless access networks are not particularly limited as long as they use wireless electromagnetic waves as transmission media.
For example, the primary base station may correspond to an LTE network, and the secondary base station may correspond to an NR network, where the primary base station is an LTE base station and the secondary base station is an NR base station. Of course, the main base station may also correspond to an NR network, and the secondary base station corresponds to an LTE network, where the main base station is an NR base station, and the secondary base station is an LTE base station.
In a specific implementation, the suspension measurement indication information may be generated by a measurement frequency configured interactively between the main base station and the secondary base station. For example, after the UE establishes the LTE-NR dual connectivity, the LTE base station may query the NR base station for a measurement frequency that the NR base station will configure for the UE, or the NR base station indicates the measurement frequency that the NR base station will configure for the UE when sending a dual connectivity configuration response message to the LTE base station. After the LTE base station knows the measurement frequency that the NR base station will configure, if the LTE base station has previously sent measurement configuration information of the frequency to the UE, the LTE base station may send suspension measurement indication information about the frequency to the UE.
In a specific implementation, the suspension measurement indication information may include suspended measurement frequency information or a suspended measurement identifier (the measurement identifier is associated with a measurement frequency), and the terminal may know the suspended measurement frequency according to the suspended measurement frequency or the measurement identifier information. The suspended frequency may be only one frequency, two frequencies, or two or more frequencies, and is not particularly limited. In other words, the suspension measurement indication information may indicate that the UE suspends cell measurement of one frequency, and may also indicate that the UE suspends cell measurement of two or more frequencies.
And 42, suspending the cell measurement of the indicated frequency according to the suspension measurement indication information when the suspension measurement indication information is received.
In a specific implementation, after receiving the indication information of measurement suspension, the UE may measure the cell of the indicated frequency to suspend temporarily, that is, not measure the cell corresponding to the suspended measurement frequency, but the UE may continue to store the measurement configuration information corresponding to the suspended measurement frequency until receiving a further indication.
For the cell with the frequency not indicated, that is, the cell corresponding to the frequency for which the suspension measurement indication information does not indicate suspension, cell measurement may be continued according to the previously received measurement configuration message.
In a specific implementation, when the suspension measurement indication information is not received, the measurement may be performed according to a measurement configuration message received in advance. The measurement configuration message received in advance may be sent by the primary base station, may also be sent by the secondary base station, and may also include both the measurement configuration message sent by the primary base station and the measurement configuration message sent by the secondary base station, but the measurement configuration messages sent by the primary base station and the secondary base station do not have measurement configuration information for the same frequency cell. Before the suspension measurement indication information is not received, cell measurement may be performed according to the measurement configuration information received in advance.
Referring to fig. 5, an embodiment of the present invention further provides another cell measurement method, where the method may include the following steps:
and step 51, suspending the cell measurement of the indicated frequency and continuing to measure the cell of the non-indicated frequency when the suspension measurement indication information is received.
For step 51, reference may be made to the above description of steps 41 and 42, which is not described herein again.
And step 52, when receiving the recovery measurement indication information, recovering the cell measurement of the frequency indicated in the recovery measurement indication information.
In a specific implementation, the frequencies or measurement identities indicated in the recovered measurement indication information may be one or more of the frequencies indicated in the suspended measurement indication information. In other words, the recovery measurement indication information may indicate that the UE recovers cell measurements of one of the suspended frequencies, and may also indicate that the UE recovers cell measurements of two or more suspended frequencies.
When the UE is required to continue to measure the cell of the suspended frequency, the UE can immediately resume the measurement of the cell on the frequency by sending the measurement resuming indication information to the UE, so as to save signaling overhead and reduce the power consumption of the UE.
As can be seen from the above, for a UE with established dual connectivity, by sending suspension measurement indication information to the UE, the UE can suspend cell measurement of a certain frequency, and compared with performing measurement and reporting measurement reports respectively, power consumption of the UE can be reduced and wireless signaling resources can be saved.

For example, the primary base station may query the secondary base station for a measurement frequency that the secondary base station will configure for the UE, or the secondary base station indicates a measurement frequency that it will configure for the UE when sending the dual connectivity configuration response message to the primary base station. After the main base station knows the measurement frequency that the secondary base station will configure, if the main base station has previously sent measurement configuration information of the frequency to the UE, the main base station may send suspension measurement indication information about the frequency to the UE.
