Detailed Description
In the scenario of dual connectivity between the L TE base station and the NR base station, the primary base station and the secondary base station need measurement results of the terminal for the same measurement frequency in some cases.
In the prior art, when the main base station and the secondary base station need the measurement result together, the main base station and the secondary base station need to perform measurement configuration for the terminal for the frequency respectively, and then the terminal performs measurement and sends the measurement result respectively based on the configuration information of the main base station and the secondary base station, which results in an increase in downlink signaling overhead and an increase in complexity of terminal processing.
The inventor of the present invention finds, through research, that in the prior art, for measurement results required by a main base station and an auxiliary base station, the main base station, the auxiliary base station and a terminal do not negotiate with each other or judge a measurement result required by another base station, and thus it is impossible to know whether there is a situation that two base stations repeatedly require measurement results of the same frequency to be measured, and therefore the terminal respectively performs measurement and sends the measurement results based on configuration information of the main base station and the auxiliary base station.
In the embodiment of the invention, when the measurement result of the frequency to be measured needs to be reported, whether the measurement result of the frequency to be measured is needed by a main base station and a secondary base station together is determined, wherein the frequency to be measured belongs to the measurement frequency of the secondary base station; and when the main base station and the auxiliary base station need the measurement result of the frequency to be measured together, reporting the measurement result to the main base station and the auxiliary base station respectively. By adopting the scheme, the terminal can respectively send the measurement results to the main base station and the auxiliary base station when the measurement results of the frequency to be measured need to be reported and the main base station and the auxiliary base station need the measurement results of the frequency together.
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. 1, fig. 1 is a flowchart of a method for reporting a measurement result of a dual connection in an embodiment of the present invention. The method for reporting the measurement result of the dual connectivity may include steps S11 to S12:
step S11: when a measurement result of the frequency to be measured needs to be reported, determining whether a main base station and a secondary base station need the measurement result of the frequency to be measured together, wherein the frequency to be measured belongs to the measurement frequency of the secondary base station;
step S12: and when the main base station and the auxiliary base station need the measurement result of the frequency to be measured together, reporting the measurement result to the main base station and the auxiliary base station respectively.
In the specific implementation of step S11, when the terminal needs to report the measurement result of the measurement frequency of a certain secondary base station, it is determined whether the primary base station and the secondary base station need the measurement result of the frequency to be measured together.
Specifically, since the main base station needs to select different secondary base stations according to the measurement result, the main base station may still need the measurement result of a certain measurement frequency when the measurement frequency belongs to the secondary base station measurement frequency but not to the main base station measurement frequency, and when the measurement frequency belongs to the main base station measurement frequency but not to the secondary base station measurement frequency, the secondary base station does not need the measurement result in a normal case, and the terminal may perform measurement and directly transmit the measurement result to the main base station according to the measurement configuration information received from the main base station.
And the secondary base station measurement frequency is a measurement frequency configured for the terminal based on the wireless access technology to which the secondary base station belongs.
In the specific implementation of step S12, when the terminal determines that the primary base station and the secondary base station need the measurement result of the frequency to be measured together, the terminal reports the measurement result to the primary base station and the secondary base station, respectively.
Specifically, the terminal uses the asn.1 coding of the primary base station, and reports the measurement result to the primary base station through an air interface message on the primary base station side, for example, through Radio Resource Control (RRC) signaling on the primary base station side; and adopting ASN.1 coding of the auxiliary base station, and reporting the measurement result to the auxiliary base station through an air interface message of the auxiliary base station side, for example, reporting through an RRC signaling of the auxiliary base station side.
For example, when the main base station is a L TE base station and the auxiliary base station is an NR base station, the terminal sends the measurement result to the main base station through RRC signaling of L TE and sends the measurement result to the auxiliary base station through RRC signaling of NR, and conversely, when the main base station is an NR base station and the auxiliary base station is a L TE base station, the terminal sends the measurement result to the main base station through the RRC signaling of NR and sends the measurement result to the auxiliary base station through the RRC signaling of L TE.
In the embodiment of the invention, the terminal can respectively send the measurement results to the main base station and the auxiliary base station when the measurement results of the frequency to be measured need to be reported and the main base station and the auxiliary base station need the measurement results of the frequency together.
Further, an embodiment of the present invention provides another method for reporting a measurement result of a dual connectivity, and a specific flowchart refers to fig. 2. The other method for reporting a measurement result of a dual connectivity may include steps S21 to S23, which are described in detail below.
In step S21, when the measurement result of the frequency to be measured needs to be reported, it is determined whether the measurement result of the frequency to be measured is needed by the primary base station and the secondary base station together according to the common sending indication cell sent by the secondary base station.
Wherein the common transmission indication cell is used for indicating whether a measurement result of the measurement frequency of each secondary base station is required by the main base station or whether the measurement result is required by both the main base station and the secondary base station. Specifically, the secondary base station may directly indicate whether the measurement result of the measurement frequency of each secondary base station is required by the primary base station and the secondary base station together by sending an indication cell together, or may implicitly indicate whether the measurement result of the measurement frequency of each secondary base station is required by the primary base station by sending an indication cell together. More specifically, since the measurement result of the measurement frequency of the secondary base station is tested based on the instruction sent by the secondary base station to the terminal, that is, the secondary base station indicates that the measurement result is needed, it is determined that the measurement result of the measurement frequency of a certain secondary base station is also needed by the primary base station, and the measurement result can be implicitly indicated as being needed by both the primary base station and the secondary base station. It should be noted that the content of the common transmission indicator cell corresponding to different measurement frequencies of the secondary base station is determined according to the specific measurement frequency of the secondary base station, and may be the same or different.
In a specific implementation, when the common sending indication cell indicates that the frequency to be measured belongs to the frequency to be measured required by the main base station, it is determined that the main base station and the secondary base station commonly require a measurement result of the frequency to be measured.
For example, for a certain secondary base station measuring frequency, 1 is used to indicate that the measurement result of the secondary base station measuring frequency is commonly required by the primary base station and the secondary base station, and 0 is used to indicate that the measurement result of the secondary base station measuring frequency is not commonly required by the primary base station and the secondary base station, that is, only the secondary base station is required; or 1 is adopted to indicate that the measurement result of the secondary base station measurement frequency is required by the main base station, and 0 is adopted to indicate that the measurement result of the secondary base station measurement frequency is not required by the main base station, namely only the secondary base station is required. It should be noted that, in the embodiment of the present invention, a specific indication manner for jointly transmitting the indication information element is not limited.
The common transmission indication information element may be included in the measurement configuration information, transmitted to the terminal by the secondary base station, or transmitted to the terminal by the secondary base station alone. The measurement configuration information may include a measurement frequency and a reporting condition, where the reporting condition is used to indicate under which conditions the terminal needs to report the measurement result of the measurement frequency, for example, periodic reporting or event-triggered reporting. As a non-limiting example, the reporting condition may include that reporting is required when the measurement signal at the measurement frequency is stronger than a certain threshold.
The common transmission indication information element may be determined by the secondary base station negotiating with the primary base station. An interface is arranged between the main base station and the auxiliary base station, negotiation can be realized through signaling interaction, and measurement results on measurement frequencies are determined to be needed by the main base station. For example, for a certain frequency to be measured, when the auxiliary base station and the main base station negotiate to determine that the measurement result of the frequency to be measured is needed together, the auxiliary base station performs measurement configuration on the terminal, and the main base station does not need to perform measurement configuration and send measurement configuration information, so that the configuration overhead and signaling overhead of the main base station can be saved.
Further, the terminal may receive the common transmission indication information element transmitted by the secondary base station through the primary base station. Specifically, the secondary base station may directly send the common transmit indication cell or the measurement configuration information to the terminal, and may also forward the common transmit indication cell or the measurement configuration information to the terminal through the primary base station.
Those skilled in the art should understand that the secondary base station forwards to the terminal through the primary base station, so that the signaling channel already established between the primary base station and the terminal can be multiplexed, and at this time, the signaling channel between the secondary base station and the terminal does not need to be established, thereby effectively saving the configuration overhead.
Specifically, in the process of establishing the dual connectivity, the terminal first accesses the main base station, the main base station and the secondary base station negotiate to configure a serving cell on the secondary base station side for the terminal, and then the main base station notifies the terminal to access the secondary base station through the main base station side RRC signaling, so that the dual connectivity between the terminal and the main base station and the secondary base station is established, and at this time, a signaling channel is already established between the main base station and the terminal.
The common transmission indication cell is transmitted through the RRC signaling of the secondary base station side. Specifically, the common transmission indication cell or the measurement configuration information is configured according to RRC signaling of the secondary base station side, whether transmitted directly to the terminal by the secondary base station or transmitted to the terminal through the primary base station.
In step S22, the measurement result is transmitted to the master base station.
Specifically, when the main base station and the secondary base station need the measurement result of the frequency to be measured together, the terminal sends the measurement result to the main base station.
In step S23, the measurement result is transmitted to the secondary base station.
Specifically, when the primary base station and the secondary base station need the measurement result of the frequency to be measured together, the terminal sends the measurement result to the secondary base station.
In the embodiment of the invention, the indication cell is sent together to indicate whether the measurement result of the measurement frequency of each auxiliary base station is required by the main base station and the auxiliary base station together, and then the terminal can directly send the measurement result to the main base station without the need of the main base station to carry out measurement configuration and send measurement configuration information.
For more details of another method for reporting measurement results of dual connectivity shown in fig. 2, please refer to the foregoing and the related description of the method for reporting measurement results of dual connectivity shown in fig. 1, which is not repeated herein.
Fig. 3 is a data flow diagram of another method for reporting a measurement result of a dual connection according to an embodiment of the present invention. The other method for reporting a measurement result of dual connectivity may include steps S31 to S35:
step S31: the auxiliary base station 33 negotiates with the main base station 31 to determine to transmit the indication cell in common;
step S32: the auxiliary base station 33 sends measurement configuration information to the terminal 32, wherein the measurement configuration information comprises a common sending indication information element;
step S33: the terminal 32 determines that the main base station 31 and the auxiliary base station 33 need the measurement result of the frequency to be measured together;
step S34: the terminal 32 transmits the measurement result to the main base station 31;
step S35: the terminal 32 sends the measurement result to the secondary base station 33.
In a specific implementation, the method may further include the step of sending, by the secondary base station 33, measurement configuration information to the primary base station 31, and then the primary base station 31 processes the measurement result according to the measurement result received from the terminal 32 and the measurement configuration information, for example, determining whether to change the secondary base station 33 to another secondary base station, or whether to release the secondary base station 33.
Further, another method for reporting a measurement result of dual connectivity is provided in an embodiment of the present invention, and a specific flowchart refers to fig. 4. The method for reporting measurement results of the dual connectivity may include steps S41 to S43, which are described in detail below.
In step S41, when the measurement result of the frequency to be measured needs to be reported, it is determined whether the measurement result of the frequency to be measured is needed by the primary base station and the secondary base station together according to the frequency that needs to obtain the measurement report and the measurement configuration information sent by the secondary base station and sent by the primary base station.
Specifically, when the secondary base station needs a measurement result of a certain frequency, measurement configuration may be performed according to the frequency, and measurement configuration information is sent to the terminal; when the main base station requires a measurement result of a certain frequency, the frequency can be directly transmitted to the terminal without performing measurement configuration and transmitting measurement configuration information to the terminal.
When the measurement result of the frequency to be measured needs to be reported, if the terminal determines that the measurement result of the frequency to be measured is needed by the main base station and the secondary base station together according to the frequency to be measured sent by the main base station and the measurement configuration information sent by the secondary base station, the measurement can be performed according to the measurement configuration information received from the secondary base station, and the measurement result is sent to the main base station and the secondary base station.
Specifically, determining whether the primary base station and the secondary base station need the measurement result of the frequency to be measured together according to the frequency to be obtained by the measurement report sent by the primary base station and the measurement configuration information sent by the secondary base station includes: and when the frequency to be measured belongs to the frequency which is sent by the main base station and needs to obtain the measurement report and is contained in the measurement configuration information, determining that the main base station and the auxiliary base station need the measurement result of the frequency to be measured together.
For example, the terminal receives measurement configuration information from the secondary base station, and receives a frequency for which a measurement report needs to be obtained from the main base station, and the frequency required by the main base station is included in the measurement configuration information, the terminal may determine that the measurement configuration of the frequency required by the main base station is configured by the secondary base station, measure the frequency based on the measurement configuration information of the secondary base station, and report the measurement result to the main base station and the secondary base station when the obtained measurement result meets a reporting condition. Wherein the reporting condition may be included in the measurement configuration information.
Further, the primary base station may send the frequency of the measurement report to be obtained through an air interface message of the primary base station side, for example, through an RRC signaling of the primary base station side, and the secondary base station sends the measurement configuration information through an air interface message of the secondary base station side, for example, through an RRC signaling of the secondary base station side.
Further, the measurement configuration information transmitted by the secondary base station may be received by the primary base station. Specifically, the secondary base station may directly send the measurement configuration information to the terminal, and may also forward the measurement configuration information to the terminal through the primary base station. As described above, the secondary base station forwards to the terminal through the primary base station, so that the signaling channel established between the primary base station and the terminal can be multiplexed, which helps to save configuration overhead.
Further, the main base station is one of an NR base station and an L TE base station, and the secondary base station is the other of the NR base station and a L TE base station, for example, when the main base station is a L TE base station, the secondary base station is an NR base station, and when the main base station is an NR base station, the secondary base station is a L TE base station.
In step S42, the measurement result and the measurement configuration information are transmitted to the master base station.
Specifically, when the terminal reports the measurement result to the main base station, the terminal may send measurement configuration information to indicate a reporting condition of the measurement result, so that the main base station can understand under what condition the measurement result is reported (for example, periodic reporting or event-triggered reporting).
It can be understood that, when the terminal reports the measurement result to the main base station, a part of the trigger conditions in the measurement configuration information may also be sent, that is, the complete measurement configuration information is not sent. Wherein the partial trigger condition enables the master base station to understand under what conditions the measurement results are reported.
For example, when the main base station is L TE base station, the auxiliary base station is NR base station, the terminal sends the measurement result to the main base station through the RRC signaling of L TE, and when the main base station is NR base station, the auxiliary base station is L TE base station, the terminal sends the measurement result to the main base station through the RRC signaling of NR.
In step S43, the measurement result is transmitted to the secondary base station.
Specifically, the terminal may adopt asn.1 coding of the secondary base station, and report the measurement result to the secondary base station through an air interface message on the secondary base station side, for example, report through an RRC signaling on the secondary base station side, for example, when the primary base station is an L TE base station and the secondary base station is an NR base station, the terminal sends the measurement result to the secondary base station through the RRC signaling of NR, and when the primary base station is an NR base station and the secondary base station is a L TE base station, the terminal sends the measurement result to the secondary base station through the RRC signaling of L TE.
In the embodiment of the present invention, the main base station may only send the frequency for which the measurement report needs to be obtained, and does not need to send complete measurement configuration information, and the terminal may determine, according to the frequency to be measured, that the main base station and the secondary base station both belong to the frequency for which the measurement report needs to be obtained, and that the measurement configuration information is included in the measurement configuration information, a measurement result of the common frequency that is commonly required by the main base station and the secondary base station.
For more details of the method for reporting measurement results of a dual connection shown in fig. 4, please refer to the foregoing description and the related descriptions of the method for reporting measurement results of a dual connection shown in fig. 1 to fig. 3, which are not repeated herein.
Fig. 5 is a data flow diagram of another method for reporting a measurement result of dual connectivity according to an embodiment of the present invention. The method for reporting measurement results of the dual connectivity may include steps S51 to S56:
step S51: the secondary base station 53 performs measurement configuration;
step S52: the secondary base station 53 transmits measurement configuration information to the terminal 52;
step S53: the main base station 51 sends the frequency at which the measurement report needs to be obtained to the terminal 52;
step S54: the terminal 52 determines that the main base station 51 and the auxiliary base station 53 need the measurement result of the frequency to be measured together;
step S55: the terminal 52 sends the measurement result and the measurement configuration information to the master base station 51;
step S56: the terminal 52 sends the measurement result to the secondary base station 53.
It should be noted that, in the specific implementation, since the measurement configuration information may be sent when the terminal 52 sends the measurement result to the main base station 51, in the embodiment of the present invention, the secondary base station 33 may not send the measurement configuration information to the main base station 31, thereby saving signaling overhead.
