Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, a Conditional PSCell addition/change is introduced into R6, and is a method for providing one or more PSCell cells or cell groups accessed by a pre-configured target for a terminal, and a network provides a specified execution condition for each pre-configured PSCell cell at the same time. And after receiving the command containing the Conditional PSCell configuration information, the terminal evaluates the preconfigured PSCell cells according to the execution conditions configured by the network side. When the pre-configured PSCell cell meets the configured execution condition, the terminal can execute access in the cell to complete PSCell addition/change process.

Taking the Conditional PSCell addition as an example, a specific flow may be that a Master base station (Master Node, MN) configures measurement configuration information for a terminal, and at this time, the terminal only has data transmission with the MN. And then the terminal triggers a measurement report to the MN, the MN prepares a pre-configured target PSCell cell for the terminal according to the measurement report, and the MN sends an SN addition request message to a target SN base station, wherein the SN addition request message carries indication information of conditional SN addition. The serving base station MN may configure the terminal with a plurality of preconfigured target PSCell cells according to the measurement report, e.g. adding SN1 and SN2, respectively, in this example. At this time, if the target SN base station decides to admit the terminal, a confirmation message of the SN addition request is generated for the terminal, wherein the confirmation message of the SN addition request contains the configuration information of the SN, and the SN addition request confirmation message is sent to the current service base station MN of the terminal. The serving base station MN sends an RRC message including configuration information and execution conditions of the pre-configured target PSCell cell to the terminal, and the terminal sends an RRC completion message to the serving base station MN as a response. And then the terminal executes measurement and evaluates the execution condition, if a certain pre-configured SN measurement result meets the execution condition, the terminal executes access at the SN, and the terminal synchronizes and triggers a random access process to a target SN meeting the execution condition. Of course, the target cell is one of the pre-configured target pscells configured for the terminal by the serving base station MN, for example SN1. After the terminal accesses the SN1, the data interaction with the SN1 can be carried out, and the SN adding process is completed.

In addition, in order to save signaling overhead, radio Resource Control (RRC) supports delta configuration. The delta configuration refers to that the reference configuration information is taken as a reference, when the network side submits the configuration information, the configuration information is provided for the terminal according to the configuration principle of different domains in the configuration information, for the domain which continues to use the reference configuration information, the network can determine whether to provide the domain according to the attribute of the domain, if the attribute of the domain does not appear, the original value of the domain is maintained, and the network can not provide the domain any more, but only provide the domain value which needs to be updated. For example, the RRC reconfiguration message supports delta configuration, for example, the attributes of field1 and field2 are default values of the field, the original values of the field are maintained, the source configuration stored in the network side and the terminal is used as reference configuration information, if the network side only wants to update the value of field2, only field2 needs to be included in the reconfiguration message, and field1 does not need to be included, and after the terminal receives the reconfiguration message, the value of field2 is updated, and the value of original field1 is used.

While a full configuration is a configuration in which the network side needs to provide all configuration information. For example, if the attributes of field1 and field2 are default, the original value of the field is maintained, if the network side only wants to update the value of field2, but if full configuration is used, the terminal will clear the original configuration message, so that not only field2 but also field1 need to be included in the reconfiguration message. If the network does not contain field1, the terminal, upon receiving the reconfiguration message, would assume that field1 was not configured and would not continue to use the value of the original field1.

Considering that the network side can provide a plurality of preconfigured SCG configuration information to the terminal in the PSCell addition and change process, the signaling overhead is increased to a large extent. Especially, in the Conditional PSCell addition process, SCG configuration information that is not stored on the network side and the terminal side is used as reference configuration information, and how to reduce signaling overhead becomes a technical problem to be solved.

In view of this, the embodiment of the present invention provides the preconfigured SCG configuration information for the terminal according to the delta configuration principle by using the configuration information specified by the protocol definition or specification as the reference configuration information, so as to reduce the signaling overhead. Specifically, the embodiments of the present invention are specifically described as follows:

as shown in fig. 1, a flowchart of the steps of a secondary cell group configuration method applied to an MN in the embodiment of the present invention is shown, where the method includes the following steps:

step 101: and configuring reference secondary cell group SCG configuration information for the terminal and the at least one pre-configured target secondary base station SN respectively.

Specifically, the MN may configure reference SCG configuration information for the terminal and at least one preconfigured target SN, respectively, so that each target SN can generate its own SCG configuration information based on the reference SCG configuration information, and the terminal can obtain complete SCG configuration information of the target SN based on the SCG configuration information and the received SCG configuration information of the target SN.

In addition, specifically, in this embodiment, when a conditional secondary cell group master cell addition (conditional PSCell addition) is performed, a conditional secondary cell group master cell is changed (conditional PSCell change) is performed, or when one or more SCGs need to be configured for the terminal in multiple connections, reference SCG configuration information may be provided for the terminal and at least one preconfigured target SN, respectively, so that when one or more preconfigured SCG configuration information needs to be provided for the terminal, the preconfigured SCG configuration information may be provided for the terminal based on the reference SCG configuration information, thereby reducing signaling overhead.

In this way, reference SCG configuration information is configured for the terminal and the target SN respectively, so that the target SN can generate self SCG configuration information based on the reference SCG configuration information, and then the terminal can obtain complete SCG configuration information of the target SN based on the reference SCG configuration information and the received SCG configuration information of the target SN.

In addition, the reference SCG configuration information may specifically include default configuration information and/or target SCG configuration information provided by the MN.

Of course, the default configuration information may include at least one of the following information: default physical layer parameters defined by a physical layer or Radio Resource Control (RRC) layer; default Media Access Control (MAC) parameters defined by a MAC layer or RRC layer; default Radio Link Control (RLC) parameters defined by the RLC layer or RRC layer; packet Data Convergence Protocol (PDCP) or RRC layer defined default PDCP parameters; default bearer parameters defined by the RRC layer; default SCG configuration information.

It should be noted that the default configuration information may be a default parameter defined by the protocol.

It should be noted that the default SCG configuration information may be at least one of a default physical layer parameter defined by the physical layer or the RRC layer, a default MAC parameter defined by the MAC layer or the RRC layer, a default RLC parameter defined by the RLC layer or the RRC layer, a default PDCP parameter defined by the PDCP layer or the RRC layer, and a default bearer parameter defined by the RRC layer, and is not specifically limited herein. Or default SCG configuration information defined by the protocol.

In addition, the target SCG configuration information may be customized reference configuration information, designated SCG configuration information, or source SCG configuration information.

Specifically, the specified SCG configuration information may be at least one of the following information:

1 st SCG configuration information in an SCG configuration list configured for the terminal; wherein, other SCG configuration information in the SCG configuration list uses the 1 st SCG configuration information as a reference, or other SCG configuration information in all SCG configuration information configured for the terminal uses the 1 st SCG configuration information as a reference;

configuring the Nth SCG configuration information in the SCG configuration list configured for the terminal; wherein, the other SCG configuration information in the SCG configuration list uses the nth SCG configuration information as a reference, or the other SCG configuration information in all the SCG configuration information configured for the terminal uses the nth SCG configuration information as a reference, and N is a positive integer greater than 1.

That is, the specified SCG configuration information may be defined in each signaling, that is, other SCG configuration information in the signaling uses the specified SCG configuration information as reference SCG configuration information, or the specified SCG configuration information may be defined for the terminal, that is, other SCG configuration information configured for the terminal uses the specified SCG configuration information as reference SCG configuration information.

Furthermore, in this embodiment, when configuring the reference SCG configuration information for at least one preconfigured target SN, a request message may be sent to the target SN, where the request message includes indication information of the reference SCG configuration information and/or adopted reference SCG configuration information;

specifically, the indication information is used to indicate any one of the following: whether the target SN uses the reference SCG configuration information, uses the default configuration information as the reference SCG configuration information, and uses the target SCG configuration information as the reference SCG configuration information.

Further, specifically, the request message may be a SN addition request message, but is not specifically limited herein.

In addition, specifically, when the reference SCG configuration information indicated by the indication information is target SCG configuration information provided by the MN, that is, the adopted reference SCG configuration information is target SCG configuration information, the target SCG configuration information may be transmitted to the target SN in advance before the MN sends the request message to the target SN; of course, the reference SCG configuration information may also be carried in the request message.

In addition, specifically, after sending the request message to the target SN, the acknowledgement information fed back by the target SN may be received, where the acknowledgement information may carry the identification information of the reference SCG configuration information; the identification information is used to indicate that the reference SCG configuration information is the default configuration information or the target SCG configuration information.

Of course, the confirmation information may be specifically the SN, and is not determined here.

In this way, in this embodiment, the reference SCG configuration information is configured for the target SN in the manner described above, so that the target SN can generate its own SCG configuration information in a delta configuration manner based on the reference SCG configuration information, thereby avoiding a problem in the prior art that the SN can only generate complete SCG configuration information when no source SCG configuration information is used as a reference in the SN adding process, which results in a large signaling overhead, and reducing the signaling overhead.

Specifically, the target SCG configuration information is customized reference configuration information, specified SCG configuration information or source SCG configuration information.

In addition, it should be noted herein that, when the target SCG configuration information is the customized reference configuration information and the reference SCG configuration information is configured for the terminal, the customized reference configuration information may be notified to the terminal through system information broadcast; or sending the self-defined reference configuration information to the terminal through RRC dedicated signaling.

The terminal is configured with the reference SCG configuration information in the mode, so that the terminal can acquire the reference SCG configuration information, the terminal can obtain the complete SCG configuration information of the target SN based on the reference SCG configuration information and the received SCG configuration information of the target SN, the network side generates the SCG configuration information of the target SN based on the reference SCG configuration information, and signaling overhead is reduced.

In this way, in this embodiment, reference SCG configuration information is configured for the terminal and the target SN, so that provision of preconfigured SCG configuration information for the terminal based on the reference SCG configuration information is achieved, and when a plurality of SCG configuration information are configured for the terminal, air interface consumption caused by configuring a plurality of SCGs can be reduced.

In addition, as shown in fig. 2, a flowchart of steps of a secondary cell group configuration method applied to an SN in the embodiment of the present invention is shown, where the method includes the following steps:

step 201: and acquiring the SCG configuration information of the reference auxiliary cell group configured by the main base station MN.

Step 202: generating SCG configuration information of itself based on the reference SCG configuration information.

Specifically, the SN may obtain reference SCG configuration information configured by the MN, and generate SCG configuration information of itself based on the reference SCG configuration information. Of course, when the SN generates its SCG configuration information based on the reference SCG configuration information, it may generate its SCG configuration information according to the principle of delta configuration, thereby reducing signaling overhead.

It should be noted that the default configuration information and the target SCG configuration information in this embodiment are the same as the default configuration information and the target SCG configuration information in the foregoing embodiment, and are not described herein again.

Specifically, the request message may be a SN addition request message, but is not specifically limited herein.

In addition, specifically, when the reference SCG configuration information indicated by the indication information is target SCG configuration information provided by the MN, that is, the adopted reference SCG configuration information is the target SCG configuration information, the target SCG configuration information may be received in advance before the SN receives the request message sent by the MN; of course, the target SCG configuration information may also be acquired in the request message as the reference SCG configuration information.

In addition, specifically, after receiving the request message sent by the MN, the apparatus may also send acknowledgement information to the MN, where the acknowledgement information carries the identification information of the reference SCG configuration information; the identification information is used to indicate that the reference SCG configuration information is the default configuration information or the target SCG configuration information.

In this way, in this embodiment, the reference SCG configuration information configured by the MN is received in the manner described above, so that the SN can generate its own SCG configuration information in the delta configuration manner based on the reference SCG configuration information, thereby avoiding a problem of large signaling overhead when the SN can only generate complete SCG configuration information, and reducing the signaling overhead.

In addition, as shown in fig. 3, a flowchart of the steps of the secondary cell group configuration method applied to the terminal in the embodiment of the present invention is shown, where the method includes the following steps:

step 301: acquiring SCG configuration information of a reference auxiliary cell group configured by the MN;

step 302: and obtaining the complete SCG configuration information of the target SN based on the reference SCG configuration information and the received SCG configuration information of the target SN.

Of course, it should be noted herein that the SCG configuration information of the target SN received by the terminal is the own SCG configuration information generated by the target SN based on the reference SCG configuration information.

Therefore, the terminal receives the reference SCG configuration information configured by the MN, and obtains the complete SCG configuration information of the target SN based on the reference SCG configuration information and the received SCG configuration information of the target SN, thereby realizing the purpose of providing the pre-configured SCG configuration information for the terminal based on the reference SCG configuration information, and reducing the signaling overhead.

In addition, specifically, the reference SCG configuration information includes default configuration information and/or target SCG configuration information provided by the MN.

It should be noted that the default configuration information and the target SCG configuration information in this embodiment are the same as the default configuration information and the target SCG configuration information in the MN-side embodiment, and are not described herein again.

In addition, further, when acquiring the reference SCG configuration information configured by the MN, the terminal may receive an RRC signaling sent by the MN, where the RRC signaling carries the SCG configuration information of each target SN and/or identification information of the reference SCG configuration information; the identification information is used to indicate that the reference SCG configuration information is the default configuration information or the target SCG configuration information.

Specifically, the target SCG configuration information is customized reference configuration information, designated SCG configuration information, or source SCG configuration information.

In addition, it should be noted herein that when the target SCG configuration information is the customized reference configuration information and the reference secondary cell group SCG configuration information configured by the MN is received, the customized reference configuration information may be received through system information broadcast; or receiving the self-defined reference configuration information through RRC dedicated signaling.

In this way, the reference SCG configuration information provided by the MN is obtained in the above manner, so that the terminal can obtain the reference SCG configuration information, and the terminal can obtain the complete SCG configuration information of the target SN based on the reference SCG configuration information and the SCG configuration information of the target SN, thereby realizing the reference SCG configuration information based and reducing the signaling overhead.

The following specifically describes embodiments of the present invention with reference to specific examples.

Of course, the default configuration information may be at least one of a default physical layer parameter defined by the RRC layer, a default MAC parameter defined by the MAC layer or the RRC layer, a default RLC parameter defined by the RLC layer or the RRC layer, a default PDCP parameter defined by the PDCP layer or the RRC layer, a default bearer parameter defined by the RRC layer, and a default SCG configuration information defined by the protocol. Or protocol defined default SCG configuration information.

And finally, after receiving the configuration information containing the pre-configured SN1 and SN2, the terminal obtains the complete configuration information of the SN1 and the complete configuration information of the SN2 based on the reference SCG configuration information.

In addition, the identification information may be configured based on each signaling, that is, the signaling includes the identification information, and then SN1 and SN2 are configured according to the identification information; the configuration may also be based on each preconfigured SN configuration, that is, SN1 and SN2 configure the identification information respectively, and configure based on information indicated by corresponding identification information, for example, SN1 notifies the terminal as reference SCG configuration information according to default configuration information, and SN2 notifies the terminal as reference SCG configuration information not according to default configuration information.

Finally, after receiving the configuration information containing the pre-configured SN1 and SN2, the terminal obtains the complete configuration information of SN1 and the complete configuration information of SN2 based on the default configuration information specified by referring to the identification information of the SCG configuration information.

It should be noted that, this example only takes the default configuration information as an example, but the same applies to other reference SCG configuration information.

Of course, it should be noted that the above example is not only applicable to the conditional PSCell addition and conditional PSCell change procedures, but also applicable to configuring one or more SCGs for the terminal on the network side in the multi-connection procedure.

Example 2-1, assume that the MN configures SN1 and SN2 for the terminal as pre-configured target SNs for the conditional PSCell addition.

At this time, the MN may transmit an SN addition request message, which includes indication information of whether to use the reference SCG configuration information, to the SN1, informing the SN1 of using the default SCG configuration information as the reference SCG configuration information, in one of the cases. At this time, SN1 generates SCG configuration information of SN1 with the default SCG configuration information as reference SCG configuration information, and notifies MN through PSCell addition confirmation message.

Secondly, the MN sends a SN addition request message to the SN1, where the SN1 is notified of using the reference SCG configuration information provided by the MN to the SN1 as a reference, and the reference SCG configuration information may be provided to the SN1 by the MN before, that is, may not be carried in the message or may be provided to the SN1 together in the message. At this time, the SN1 generates SCG configuration information of the SN1 with reference SCG configuration information provided by the MN, and adds an acknowledgement message to the MN through the PSCell.

Thirdly, the MN sends an SN addition request message to the SN1, which includes indication information of whether to use the reference SCG configuration information, and informs the SN1 not to use the reference SCG configuration information. Or does not carry the indication. At this time, SN1 generates SCG configuration information in a full configuration manner, and notifies MN through PSCell addition acknowledgement message.

Example 2-2, assume that the MN configures SN1 and SN2 for the terminal as pre-configured target SNs for the conditional PSCell addition. The MN sends an SN addition request message to the SN1, where the SN addition request message includes reference SCG configuration information, where the reference SCG configuration information may be the reference SCG configuration information defined in the foregoing embodiment 1-1, or may be configuration information of an SN currently served by the terminal.

It should be noted that the above is not only applicable to the conditional PSCell addition/change procedure, but also applicable to the case where one or more SCGs are configured for a terminal in multi-connection.
