Technical field

The embodiments of the present application relate to the field of communications, and in particular, to an information processing method, a base station, and a terminal.

Background technique

In the future 5th generation (5G) network construction, you can use dual connection (DC) between Long Term Evolution (LTE) and New Radio (NR) systems (referred to as "LTE". -NR DC"), enabling the terminal to obtain radio resources from both LTE and NR air interfaces, improving radio resource utilization and increasing transmission rate.

In the foregoing LTE-NR DC scenario, the primary base station and the secondary base station are different base stations, for example, the primary base station is an LTE base station and the secondary base station is an NR base station. In this scenario, how the terminal acquires the NR PDCP configuration is an urgent problem to be solved.

Summary of the invention

An embodiment of the present application provides an information processing method, a base station, and a terminal, which are used to solve the problem that a terminal existing in an LTE-NR DC scenario acquires an NR PDCP configuration.

In order to solve the above problems, the present application provides the following technical solutions:

In a first aspect, the present application provides an information processing method, where the method includes: receiving, by a primary base station, an NR PDCP configuration from a secondary base station, and identifying information of a data radio bearer (DRB) corresponding to the NR PDCP configuration, where After receiving the NR PDCP configuration and the ID information of the DRB, the base station forwards the NR PDCP configuration and the ID information of the DRB to the terminal, where the primary base station and the secondary base station are base stations of different standards. It can be seen from the above that in the first aspect of the present application, if the primary base station and the secondary base station are in different formats, if the existing LTE DC mechanism is used, the primary base station may not be able to resolve the content sent by the secondary base station, which may result in Discard directly. In order to prevent the problem from occurring in the LTE-NR DC scenario, the secondary base station directly transmits the NR PDCP configuration and the identification information of the DRB corresponding to the NR PDCP configuration to the primary base station through the interface between the primary and secondary base stations, and the primary base station does not resolve. The NR PDCP configuration generated by the secondary base station directly forwards the received NR PDCP configuration and the corresponding DRB identification information to the terminal.

In a possible implementation, the primary base station receives the NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration, where the primary base station receives the first container that includes the NR PDCP configuration from the secondary base station. a container, and receiving, from the secondary base station, the identifier information of the DRB corresponding to the NR PDCP configuration, wherein the first container and the identifier information of the DRB are in one-to-one correspondence, and then the primary base station configures the identifier information of the DRB corresponding to the NR PDCP. And a first container transmitting terminal that only includes the NR PDCP configuration. Therefore, in the implementation, the secondary base station only encapsulates the generated NR PDCP configuration into a container and sends it to the primary base station. For the primary base station, on one hand, the primary base station does not need to parse the content of the first container. Therefore, the first container is not considered to be an error packet, and finally the NR PDCP configuration is successfully sent to the terminal through the first container, which effectively solves the problem of how the secondary base station sends the configuration to the terminal.

In a possible implementation, the primary base station receives the NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration, specifically, the primary base station receives the NR PDCP configuration from the secondary base station, and the NR PDCP The first container of the identifier information of the corresponding DRB is configured, where the NR PDCP configuration corresponds to the identifier information of the DRB. Then, the primary base station sends the first container to the terminal. It can be seen that the difference from the above implementation is that the first container includes the NR PDCP configuration of the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration, that is, the first The container includes the NR PDCP configuration of the secondary base station and the identification information of the DRB corresponding to the NR PDCP configuration, which improves the diversity of the solution.

In a possible implementation, the primary base station may send an interface message between the primary base station and the secondary base station, for example, a secondary base station add request acknowledgement (SgNB addition request acknowledge) message, and a secondary base station change request acknowledgement (SgNB modification request acknowledge) message. The SgNB modification required message, the SgNB change required message, and the like, the receiving base station sends the NR PDCP configuration, and the ID information of the DRB corresponding to the NR PDCP configuration.

In a possible implementation, the primary base station further receives the second container from the secondary base station, where the second container includes the air interface configuration of the secondary base station, where the air interface configuration of the secondary base station does not include the foregoing NR PDCP configuration, and the primary base station The second container received from the secondary base station is sent to the terminal, and the second container also has a one-to-one correspondence with the identification information of the DRB. In this implementation, the primary base station sends the NR PDCP configuration to the terminal, and sends the air interface configuration of the secondary base station to the terminal to ensure the integrity of the solution.

In a possible implementation, both the primary base station and the secondary base station use NR PDCP, that is, both the primary base station and the secondary base station use the NR PDCP protocol.

In a second aspect, the present application provides an information processing method, where the method includes: a secondary base station generates an NR PDCP configuration, and the secondary base station sends an NR PDCP configuration to the primary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration, so that the primary The base station forwards the NR PDCP configuration to the terminal, and the identifier information of the DRB corresponding to the NR PDCP configuration, where the primary base station and the secondary base station are base stations of different standards.

In a possible implementation, the secondary base station generating the NR PDCP configuration includes: the secondary base station generates a first container that only includes the NR PDCP configuration. The secondary base station sends the NR PDCP configuration to the primary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration includes: the secondary base station sends the first container generated by the secondary base station to the primary base station, where the identifier information of the first container and the DRB is one by one. correspond.

That is, in the present implementation, another manner in which the secondary base station transmits the NR PDCP configuration to the primary base station and the identification information of the DRB corresponding to the NR PDCP configuration is proposed, which improves the diversity of the scheme.

The NR PDCP configuration is in one-to-one correspondence with the identifier information of the DRB, where the first container is generated by the secondary base station.

In a possible implementation, the terminal further receives, from the primary base station, a second container that includes an air interface configuration of the secondary base station, where the air interface configuration of the secondary base station does not include the NR PDCP configuration.

After that, the first base station can send the NR PDCP configuration (PDCP layer configuration information corresponding to the NR protocol) to the terminal, and proposes a specific transmission scenario in which the base station can send the NR PDCP configuration to the terminal, thereby improving the implementability of the solution.

In a possible implementation, when the terminal accessing the first base station enters an active state from an idle state, the first base station determines that the terminal supports the NR PDCP protocol or supports dual connectivity functions of the LTE system and the NR system. The first base station receives the capability information of the terminal from the core network device; the first base station determines, according to the capability information of the terminal, that the terminal supports the NR PDCP protocol or supports the dual connectivity function between the LTE system and the NR system. That is, since the core network device stores the capability information of the terminal, when the state mode of the terminal is changed, the first base station can directly obtain the capability information of the terminal from the core network, and avoid the first base station actively acquiring the terminal, so in this implementation In the process of performing state switching, after the first base station determines that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, the first base station may send the NR PDCP configuration to the terminal, and propose another The transmission scenario of the NR PDCP configuration can be sent, improving the implementability and diversity.

The second base station has acquired the capability information of the terminal, and the first base station can directly acquire the capability information of the terminal from the second base station when the terminal switches from the second base station to the first base station. In this implementation, in the process of the terminal switching from the second base station to the first base station, once the first base station determines that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, the first base station may The NR PDCP configuration is sent, and another transmission scenario in which the base station can transmit the NR PDCP configuration is proposed.

In a possible implementation, the terminal accesses the first base station and the second base station respectively, the first base station is the NR base station as the primary base station, the second base station is the LTE base station as the secondary base station, and the primary base station and the secondary base station form a dual connectivity scenario.

In the embodiment of the present application, the DRB refers to a data radio bearer between the terminal and the base station, and is used to carry data transmitted between the base station and the terminal. Referring to FIG. 2, FIG. 2 is a schematic diagram of a DRB provided in the embodiment of the present application. As shown in FIG. 2, the DRB type provided by the embodiment of the present application includes a primary cell group bearer (MCG bearer) and a secondary cell group bearer (SCG). Bearer), as well as a split bearer. The split bearer further includes a offload bearer of the data anchor point on the primary base station and a offload bearer of the data anchor point on the secondary base station, wherein the offload bearer of the data anchor point on the primary base station may be referred to as a primary cell component flow bearer (MCG split bearer) The offloaded bearer of the data anchor on the secondary base station may be referred to as a secondary cell component bearer (SCG split bearer).

Specifically, the MCG bearer refers to a bearer protocol in which only the primary base station uses the transmission resources of the primary base station, and therefore, uplink or downlink data on the MCG bearer is transmitted only through the primary base station. The SCG bearer refers to a bearer protocol where only the secondary base station uses the transmission resources of the secondary base station, and therefore, the uplink or downlink data on the SCG bearer is transmitted only through the secondary base station. The split bearer refers to a bearer protocol in which the primary base station and the secondary base station simultaneously use the transmission resources of the primary base station and the secondary base station, and the primary base station and the secondary base station can simultaneously perform data transmission with the terminal. Further, for the split bearer, if the MCG split bearer is used, the downlink data sent by the core network is offloaded to the secondary base station by the Packet Data Convergence Protocol (PDCP) layer of the primary base station in the downlink direction. And the secondary base station sends the downlink data of the offload to the terminal; in the uplink direction, if the uplink supports the offload, the primary base station and the secondary base station respectively receive the uplink data from the terminal, and the secondary base station sends the received uplink data to the primary base station again. The primary base station reorders the uplink data received from the primary base station and the secondary base station, and then sends the received data to the core network in sequence.

It can be understood that, for the MCG bearer and the SCG bearer, the data transmitted on the primary base station and the data transmitted on the secondary base station belong to different services, for example, the voice service data is transmitted on the primary base station, and the video service data is transmitted on the secondary base station; for the split bearer, The data transmitted on the primary base station and the data transmitted on the secondary base station belong to different data of the same type of service, which is not limited in this embodiment of the present application.

For example, in the embodiment of the present application, the PDCP layer of the MCG bearer, the SCG bearer, and the split bearer may be in the format of the PDCP layer specified by the NR protocol. In the embodiment of the present application, the PDCP layer specified by the NR protocol may be simply referred to as NR PDCP layer. The other protocol layers, such as the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY), are still used for the above four bearer modes. They are independent in different systems.

In the above scenario, each DRB corresponding configuration includes the configuration information of the NR PDCP layer, which is referred to as an NR PDCP configuration in the embodiment of the present application, and the NR PDCP configuration has a one-to-one correspondence with the DRB, and different DRBs have corresponding NR PDCP configurations. For example, the DRG is an MCG bearer. The MCG bearer corresponds to a set of NR PDCP configurations. The NR PDCP configuration corresponding to the MCG bearer may include, but is not limited to, the following information:

1. The duration setting of the discard timer (discardTimer) is used by the NR PDCP layer on the terminal to determine when to delete the PDCP service data unit (SDU) buffered in the buffer, corresponding to the PDCP SDU. PDCP protocol data unit (PDU);

2. The header compression parameter is used to indicate header compression profile information used when the data packet is transmitted between the primary base station and the terminal;

3. The duration setting of the reordering timer (t-reordering) is used to indicate a timer used by the NR PDCP layer on the terminal to perform a reordering operation;

4. Status report information, which is used to indicate whether the terminal opens the NR PDCP status report in the RLC determination mode (AM mode);

5. PDCP serial number (SN) length indication;

It should be noted that the foregoing NR PDCP configuration is only an example, and does not limit the NR PDCP configuration involved in the present application. The NR PDCP configuration may have other configuration information/parameters depending on the actual application scenario.

Referring to FIG. 3, FIG. 3 is a schematic diagram of signaling interaction of an embodiment of an information processing method according to an embodiment of the present disclosure, including:

101. The secondary base station generates an NR PDCP configuration.

Further, the secondary base station sends the NR PDCP configuration to the primary base station, and the identification information of the DRB corresponding to the NR PDCP configuration.

There is a one-to-one mapping relationship between the NR PDCP configuration and the DRB. The NR PDCP configuration may be an NR PDCP configuration corresponding to any one or more of the SCG bearer and the SCG split bearer.

In this embodiment, the secondary base station separately generates an NR PDCP configuration, where there is a one-to-one mapping relationship between the NR PDCP configuration and the DRB.

102. The primary base station receives an NR PDCP configuration from the secondary base station, and identifier information of the DRB corresponding to the NR PDCP configuration.

The identifier information of the DRB may be a DRB identity (DRB ID), or other information that may be used to identify the DRB. Specifically, the identifier information may be in the form of a character string and/or a number. This is not specifically limited. It can be understood that different DRBs can be distinguished by different identification information.

In some embodiments of the present application, the secondary base station may send the foregoing NR PDCP configuration and the identifier information of the DRB corresponding to the NR PDCP configuration to the primary device in a plurality of manners through a logical interface with the primary base station, for example, an X2 interface. For the sake of understanding, the eNB is used as the primary base station (MeNB) and the gNB is used as the secondary base station (SgNB) as an example.

Example 1: As shown in Figure 4, taking the EN-DC dual-connection scenario as an example, when the MeNB determines that a bearer needs to be established on the SgNB (for example, SCG bearer, and/or SCG split bearer), it will pass the MeNB and the SgNB. The X2 interface sends a SgNB addition request message to the SgNB, and after receiving the SgNB addition request message, the SgNB feeds back to the MeNB a corresponding SgNB addition request acknowledge message, the SgNB addition message. The request acknowledge includes the DRB-related parameters established on the SgNB. In the embodiment of the present application, the SgNB adds the mapping relationship between the NR PDCP configuration and the DRB in the SgNB addition request acknowledge message, that is, in the embodiment of the present application, the SgNB can pass the SgNB. The SgNB addition request acknowledge message sends the generated NR PDCP configuration and the DRB mapping relationship to the primary base station.

Example 2: As shown in FIG. 5, the SgNB may also configure the NR PDCP by using a SgNB modification request acknowledge message, and send the identifier information of the DRB corresponding to the NR PDCP configuration to the MeNB, that is, the SgNB will be the NR. The PDCP configuration, and the identifier information of the DRB corresponding to the NR PDCP configuration is sent to the MeNB in the SgNB modification request acknowledge, where the SgNB modification request acknowledge message is sent after the secondary base station receives the secondary base station table request request message (SgNB modification request). Message.

It should be noted that, in addition to transmitting the mapping relationship between the NR PDCP configuration and the DRB by using the SgNB addition request acknowledge message or the SgNB modification request acknowledge message, the SgNB modification required message may be triggered by the secondary base station. Or, the NR PDCP configuration and the ID information of the DRB are sent to the primary base station by using the SgNB change required message or the other information sent by the secondary base station to the primary base station, which is not limited in this embodiment.

It should be understood that when the terminal establishes a DRB with the base station, the bearer between the terminal and the core network device is first established. For example, in an EN-DC scenario, the bearer may be an evolved packet system (EPS) bearer, and the terminal may establish an EPS bearer with a packet data network gateway (PDN-GW), where the EPS bearer includes a DRB. An EPS bearer of the terminal may correspond to one DRB, and an EPS bearer identifier (EPS ID) is used to identify an EPS bearer of the terminal. That is to say, the NR PDCP configuration of each DRB also corresponds to one EPS bearer. However, if the secondary base station is the NR SgNB, the secondary base station cannot identify the EPS bearer. Therefore, the secondary base station does not send the mapping relationship between the NR PDCP configuration and the EPS bearer to the primary base station. In order to enable the primary base station to know which bearer the NR PDCP configuration is received, the embodiment of the present application provides a manner in which the secondary base station sends an EPS ID to the primary base station.

103. The primary base station sends an NR PDCP configuration to the terminal, and identifier information of the DRB corresponding to the NR PDCP configuration. In the embodiment of the present application, after the primary base station learns the NR PDCP configuration sent by the secondary base station and the identifier information of the DRB corresponding to the NR PDCP configuration, the NR PDCP is configured, and the identifier information of the DRB corresponding to the NR PDCP configuration is notified to the terminal. . When the primary base station and the secondary base station are in different formats, the primary base station directly forwards the relationship between the NR PDCP configuration and the DRB to the secondary base station, and does not analyze the NR PDCP configuration generated by the secondary base station, thereby effectively solving the problem. The secondary base station issues the NR PDCP configuration to the terminal.

104. The terminal performs PDCP layer configuration on the DRB according to the NR PDCP configuration and the identifier information of the DRB.

After receiving the NR PDCP configuration and the identifier information of the DRB corresponding to the NR PDCP configuration, the terminal may determine the NR PDCP configuration corresponding to the established DRB by using the identifier information of the DRB, thereby performing PDCP on the DRB by using the NR PDCP configuration. The configuration of the layer, in turn, ensures that the data on the DRB is transmitted normally.

In some embodiments of the present application, the primary base station receives the NR PDCP configuration from the secondary base station, and the identifier information of the DRB corresponding to the NR PDCP configuration includes:

The primary base station receives the first container and the identifier information of the DRB from the secondary base station, and the first container only includes the NR PDCP configuration;

The first container has a one-to-one correspondence with the identification information of the DRB. The secondary base station generates a first container including only the NR PDCP configuration in the form of a container, and sends the first container to the primary base station.

It should be noted that the first container includes only the NR PDCP configuration generated by the secondary base station, which can be understood as: the secondary base station sets an independent first container for the NR PDCP configuration generated by the secondary base station, and the first container distinguishes and encapsulates other information. Container.

It should be understood that, for the LTE-NR DC scenario, because the primary base station and the secondary base station use different radio access technologies (RATs), the NR PDCP generated by the secondary base station is not recognized by the primary base station, if the secondary base station The NR PDCP configuration is directly sent to the primary base station, and the primary base station may configure the NR PDCP sent by the secondary base station as an error packet to perform other processing, such as RRC reconnection. With the embodiment of the present application, the secondary base station generates the first container including the NR PDCP configuration in the form of a container, and sends the first container including the NR PDCP configuration to the primary base station. For the primary base station, the primary base station does not need to be configured. The content of the first container is parsed, but is directly transmitted to the terminal for parsing. Therefore, the received first container is not considered to be an error packet, and the other processing is not performed, which can effectively reduce unnecessary system overhead. .

In combination with the foregoing embodiment, the sending, by the primary base station, the NR PDCP configuration and the identifier information of the DRB to the terminal includes:

The primary base station sends, to the terminal, identification information including only the first container of the NR PDCP configuration and the DRB.

That is, after receiving the first container and the identification information of the DRB sent by the secondary base station, the primary base station sends the identifier information of the first container and the DRB to the terminal.

After the secondary base station encapsulates the generated NR PDCP configuration into a container and sends the identifier information to the primary base station, and sends the identifier information of the DRB corresponding to the first container to the primary base station, the primary base station sends the identifier information of the DRB corresponding to the first container. And the terminal directly forwards the first container to the terminal in a transparent manner, so that the terminal can obtain the NR PDCP configuration generated by the secondary base station according to the first container, and determine, according to the received identification information, the NR PDCP configuration. DRB, here, the secondary base station successfully configures the NR PDCP to the terminal.

The primary base station receives, from the secondary base station, a first container that includes only the NR PDCP configuration and the identifier information of the DRB; the NR PDCP configuration corresponds to the identifier information of the DRB bearer. Therefore, in this embodiment, the secondary base station sends the generated NR PDCP configuration and the ID information of the DRB to the primary base station in the form of a container, that is, the secondary base station generates the NR PDCP configuration along with the DRB corresponding to the NR PDCP configuration. The identification information is encapsulated into a container and sent to the primary base station. Similarly, for the primary base station, the primary base station does not need to parse the content of the first container, and does not consider that the received first container is an error packet, so the above other processing is not performed, and unnecessary system overhead can be effectively reduced. .

In combination with the foregoing embodiment, the sending, by the primary base station, the NR PDCP configuration and the ID information of the DRB to the terminal includes: the primary base station sending the first container to the terminal.

After the secondary base station encapsulates the generated NR PDCP configuration and the identifier information of the DRB corresponding to the NR PDCP configuration into the first container, the primary base station directly forwards the first container to the terminal in a transparent manner, so that the terminal The NR PDCP configuration generated by the secondary base station and the identification information of the DRB corresponding to the NR PDCP configuration may be obtained according to the first container, so that the secondary base station successfully configures the NR PDCP to the terminal.

In the embodiment of the present application, after the RRC connection is established between the primary base station and the terminal, the primary base station triggers an RRC connection reconfiguration process. For example, when the air interface configuration needs to be sent to the terminal, the primary base station sends an RRC weight to the terminal. The configuration message, the RRC reconfiguration message contains various information element (information element) parameters with different functions. Here is a practical example. For example, taking the SCG split bearer as the data anchor point, the SCG split bearer is assumed to be the DRB ID1. When the secondary base station receives the bearer setup request from the primary base station, the secondary base station requests the DRB according to the primary base station. ID1, generates a corresponding NR PDCP configuration, and only encapsulates the NR PDCP configuration in the container1 and sends the corresponding DRB ID1 identification information to the primary base station. The primary base station sets the identifier information of the container 1 and the DRB ID1 corresponding to the container1 in the RRC reconfiguration message in the form of an IE parameter, and sets the NR PDCP corresponding to the DRB ID1 and the DRB ID1 through the RRC reconfiguration message. The configuration is sent to the terminal. Specifically, the NR PDCP configuration corresponding to the DRB ID and the DRB ID is sent to the terminal by using an RRC reconfiguration message, including the following two exemplary methods:

Example 1, the NR PDCP configuration and the ID information of the DRB may be in the form of an RRC reconfiguration message as shown in FIG. 6:

As shown in FIG. 6 , in the embodiment of the present application, the RRC reconfiguration message sent by the primary base station to the terminal includes an IE, and the IE may be in the form of a list, where the list may be a public packet convergence protocol list. In the example, it is called "CommonPDCPConfigList"). Each item in the list includes a container corresponding to the NR PDCP configuration and a DRB ID (DRB ID) corresponding to the container. Different containers correspond to different DRB IDs, and different DRBs have different DRB IDs. In order to facilitate understanding of the mapping relationship between the DRB ID and the container, a practical example will be described here. For example, for the MCG bearer, the PDCP layer is located on the primary base station. Once the primary base station is configured with the MCG bearer, the primary base station generates the NR PDCP configuration corresponding to the MCG bearer in the form of a container, and uses the container and the corresponding DRB ID as One of the lists. For the same reason, for MCG split bearer, the processing method is exactly the same as MCG bearer. For the SCG bearer, the PDCP layer is located on the secondary base station. Once the secondary base station is configured with the SCG bearer, the secondary base station generates the NR PDCP configuration corresponding to the bearer in the form of a container, and the container and the corresponding DRB ID are sent to the primary base station. The primary base station receives the container and the corresponding DRB ID from the secondary base station as one of the lists. For the same reason, for SCG split bearer, the processing method is exactly the same as SCG bearer.

It can be seen that the embodiment of the present application proposes a specific form of configuring the NR PDCP configuration and the DRB ID in the RRC reconfiguration message.

It should be noted that, in the embodiment of the present application, there is another manner that the RRC reconfiguration message sent by the primary base station to the terminal includes a public packet convergence protocol list, and each item in the list includes one Container, the container contains only the DRB ID and the NR PDCP configuration corresponding to the DRB ID.

For example mode 2, the NR PDCP configuration and the ID information of the DRB may also be in the form of an RRC reconfiguration message as shown in FIG. 7:

As shown in FIG. 7, in the RRC reconfiguration message sent by the primary base station to the terminal, a "CommonPDCPConfigList" IE is also defined in the embodiment of the present application, but differs from the manner shown in FIG. 6: In the CommonPDCPConfigList, only for the split bearer, each item in the list may contain a container corresponding to the NR PDCP configuration and the corresponding DRB ID, or each item in the list may contain a container, and the container only contains NR PDCP configuration and corresponding DRB ID.

For the two bearers of the MCG bearer and the SCG bearer, the IE location of the NR PDCP configuration corresponding to the MCG bearer and the SCG bearer is unchanged as shown in FIG. 7 , and the container corresponding to the MCG bearer is configured to be carried in the RRC reconfiguration message. In the "DBR-ToAddMod" IE, the corresponding provider of the SCG bearer is configured in the "DBR-ToAddModListSCG" IE carried in the RRC reconfiguration message, except that the original PDCP configuration parameter is replaced with a container, and the container includes the MCG bearer. And the NR PDCP configuration corresponding to the SCG bearer bearer. It can be seen that the embodiment of the present application provides another specific form for configuring the NR PDCP configuration and the DRB ID in the RRC reconfiguration message.

In the implementation of the present application, the terminal performs PDCP layer processing on the data on the DRB by using the obtained NR PDCP configuration and the ID information of the DRB.

For uplink data transmission, the terminal performs PDCP layer processing on the sent data, including: performing header compression on the transmitted data; performing encryption/integrity protection on the user plane data and control plane data of the uplink transmission; and performing integrity on the control plane data. Protection and other processing. For downlink data transmission, the terminal performs PDCP layer processing on the received data, including: performing corresponding decompression on the received data stream; performing decryption/integrity check on the user plane data and the control plane data of the downlink transmission; and performing control plane data on the control plane data Processing such as integrity check. It should be noted that, in the specific processing procedure of the NR PDCP layer, the NR PDCP configuration corresponding to the type of the actual DRB determines that the terminal performs the corresponding NR PDCP layer processing, which is not limited herein, and will be described in detail in the next embodiment.

It should be noted that, in actual applications, the air interface configuration information corresponding to the DRB includes: a PDCP configuration, an RLC configuration, a MAC configuration, and a logical channel configuration. In some implementations of the present application, the secondary base station separately generates the first container according to the NR PDCP configuration, and separately generates the air interface configuration of the other secondary base station, such as the RLC configuration, the MAC configuration, and the logical channel configuration. The second container. In addition to transmitting the first container and the corresponding DRB ID to the primary base station, the secondary base station may also send the second container and the corresponding DRB ID to the primary base station. The primary base station sends the first container and the DRB ID to the terminal from the secondary base station. In addition, the primary base station sends the second container and the DRB ID received from the secondary base station to the terminal.

There is another implementation in this embodiment. The secondary base station separately generates a first container by using the NR PDCP configuration and the corresponding DRB ID, and the secondary base station separately generates air interface configurations of other secondary base stations, such as RLC configuration, MAC configuration, and logical channel configuration, and the corresponding DRB IDs. Another second container. The secondary base station sends the first container and the second container to the primary base station. The primary base station sends the first container and the second container received from the secondary base station to the terminal.

Referring to FIG. 8 , taking the SCG split bearer as an example, the SCG split bearer is assumed to be the DRB ID1. According to the DRB ID1, the secondary base station generates the NR PDCP configuration corresponding to the DRB ID1, and encapsulates the NR PDCP configuration in a container. In the NR PDCP configuration container, the secondary base station also generates an air interface configuration of the secondary base station according to the DRB ID1. The air interface configuration of the secondary base station includes: RLC configuration, MAC configuration, and logical channel configuration. In another container (referred to as a secondary base station air interface configuration container in the application embodiment). The secondary base station sends the NR PDCP configuration container, the secondary base station air interface configuration container, and the DRB ID1 together to the primary base station.

According to the DRB ID1, the primary base station configures an air interface corresponding to the primary base station, and the air interface configuration of the primary base station includes: an RLC configuration, a MAC configuration, and a logical channel configuration of the primary base station. The primary base station sends the DRB ID1, the NR PDCP configuration container, the secondary base station air interface configuration container, and the air interface configuration of the primary base station to the terminal.

In this embodiment, there is another implementation. According to the DRB ID1, the secondary base station will generate the NR PDCP configuration corresponding to the DRB ID1, and encapsulate the NR PDCP configuration and the DRB ID1 together in a container (referred to as an NR PDCP configuration container in the embodiment of the present application), and according to the DRB ID1, The secondary base station also generates an air interface configuration of the secondary base station, where the air interface configuration of the secondary base station includes: RLC configuration, MAC configuration, and logical channel configuration of the secondary base station, and the DRB ID1 is encapsulated in another container (referred to in the application embodiment). Configure the container for the secondary base station air interface. The secondary base station sends the NR PDCP configuration container and the secondary base station air interface configuration container to the primary base station.

According to the DRB ID1, the primary base station will configure the air interface corresponding to the primary base station, and the air interface configuration of the primary base station includes: DRB ID1, RLC configuration of the primary base station, MAC configuration, and logical channel configuration. The primary base station sends the NR PDCP configuration container, the secondary base station air interface configuration container, and the primary base station air interface configuration to the terminal.

The configuration process of the SCG bearer, the MCG split bearer, and the MCG bearer is similar to that of the SCG split bearer, and is not described here.

In order to facilitate the understanding of the implementation of the present application, the application embodiment will be described by taking an example of the downlink transmission of the video service data by using the SCG split bearer in the EN-DC dual-connection scenario. Referring to FIG. 9, FIG. 9 is another schematic flowchart of an embodiment of an information processing method according to an embodiment of the present disclosure, including:

201. The SgNB generates a first container corresponding to the SCG split bearer.

In this embodiment, the SgNB separately generates the NR PDCP configuration corresponding to the SCG split bearer, and there is a one-to-one mapping relationship between the NR PDCP configuration and the DRB, and there is also a one-to-one correspondence between the air interface configuration of the SgNB and the DRB. Mapping relationship.

Optionally, the air interface configuration of the SgNB generated by the SgNB, the air interface configuration of the SgNB includes: an RLC configuration, a MAC configuration, and a logical channel configuration, and the SgNB encapsulates the air interface configuration of the SgNB in the second container. It can be understood that the second container and the first container are two independent containers, that is, the first container includes the NR PDCP configuration corresponding to the SCG split bearer; and the second container includes the air interface configuration of the secondary base station. The second container may be referred to as a secondary base station air interface configuration container.

The foregoing NR PDCP configuration may include one or more combinations of the following information:

The duration of the discardTimer is configured to configure the NR PDCP layer on the terminal to determine when to delete the PDCP SDU buffered in the buffer and the PDCP PDU corresponding to the PDCP SDU.

2. The header compression parameter is used to indicate profile configuration information of the header compression when the data packet is transmitted between the primary base station and the terminal;

3. The duration setting of the t-reordering is used to indicate a timer in the reordering operation of the terminal NR PDCP layer;

5. PDCP SN length indication.

That is, after the SCG split bearer is established, it is necessary to determine the relevant configuration information used when the SCG split bearer transmits data.

202. The SgNB sends the first container and the DRB ID generated by using the SgNB addition request acknowledge edge message to the MeNB.

Optionally, the second container is further included in the SgNB addition request acknowledge message. Specifically, as shown in FIG. 10, the SgNB sends the generated NR PDCP configuration into a container and sends it to the primary base station. In addition, the SgNB encapsulates other air interface configuration information (other configurations than the NR PDCP configuration), for example, the RLC configuration of the SgNB, the MAC configuration, and the logical channel configuration into another container, and in the same manner, the above two containers are And the corresponding DRB ID is sent to the MeNB together.

That is, in the embodiment of the present application, the SgNB can send the mapping between the generated NR PDCP configuration and the DRB through the X2 interface message to the primary base station, and the mapping between the secondary station air interface configuration and the DRB generated by the SgNB. The X2 interface message is provided to the primary base station, and the specific providing process is similar to the process of mapping the NR PDCP configuration and the DRB that the SgNB will generate, and is not cumbersome here.

203. The MeNB receives the first container, the DRB ID, and the air interface configuration of the primary base station generated by the MeNB, and sends the configuration to the terminal through the Uu interface.

Optionally, when the MeNB receives the second container, the MeNB sends the second container to the terminal together with the first container, the DRB ID, and the air interface configuration of the primary base station generated by the MeNB. Specifically, as shown in FIG. 11, after acquiring the first container and the second container from the secondary base station, and the DRB ID corresponding to the two containers, the MeNB sends the RRC reconfiguration message to the terminal by using an RRC reconfiguration message, where the RRC reconfiguration message is sent. It also includes the MeNB's own primary base station air interface configuration.

204. The terminal acquires required configuration information from the RRC configuration information sent by the MeNB.

After receiving the RRC reconfiguration message from the MeNB, the terminal may obtain the NR PDCP configuration of the secondary base station, the air interface configuration of the secondary base station, and the air interface configuration of the MeNB itself.

205. The terminal performs data transmission with the MeNB and the SgNB, respectively.

Specifically, the core network sends the downlink transmission video service data to the terminal by using the SCG split bearer, that is, the core network needs to send the video service data of the terminal to the SgNB, and the video service data is offloaded by the SgNB, and a part of the video service data is sent by the MeNB. To the terminal, a part of the data is directly sent to the terminal through the SgNB. Before the core network transmits the video service data, the MeNB and the SgNB need to respectively establish a split bearer corresponding to the terminal. The established split bearer is assigned the corresponding DRB ID. Therefore, for the terminal, the configuration information related to the L2 layer (Layer 2) corresponding to the split bearer can be determined by the DRB ID. Since the terminal has obtained the L2 layer configuration sent by the MeNB in step 204, the terminal can utilize the terminal. The L2 layer configuration sent by the MeNB receives the video service data downlinked by the core network.

As shown in the above description, there is another implementation in this embodiment, that is, the SgNB generates a first container and a second container corresponding to the SCG split bearer, where the first container includes only the NR PDCP configuration corresponding to the SCG split bearer. Corresponding DRB ID, the second container includes the air interface configuration of the SgNB corresponding to the SCG split bearer and the corresponding DRB ID, for example, the RLC configuration, the MAC configuration, and the logical channel configuration of the SgNB. The SgNB sends the first container and the second container to the primary base station through the X2 interface. The MeNB receives the two containers from the SgNB, and the air interface configuration of the MeNB generated by the MeNB is sent to the terminal through the Uu interface.

Referring to FIG. 12, FIG. 12 is a schematic flowchart of an embodiment of an information processing method according to an embodiment of the present disclosure, including:

301. The base station determines that the terminal supports the NR PDCP protocol, or determines that the terminal supports the dual connectivity function of the LTE system and the NR system.

In the embodiment of the present application, the base station determines that the terminal supports the NR PDCP protocol, or determines that the terminal supports the dual connectivity function between the LTE system and the NR system. There are three scenarios, as described below:

In the first scenario, when the terminal initially accesses the primary base station, the terminal triggers an attach process, and the attach process includes a process in which the terminal reports capability information to the core network device, specifically, the terminal sends the access to the accessed base station. The capability information, the base station forwards the capability information reported by the terminal to the core network device, and thus, when the terminal initially accesses the base station, the base station can know the capability information of the terminal, and if the capability information of the terminal indicates that the terminal supports the NR PDCP protocol. Or supporting the dual connectivity function of the LTE system and the NR system, when the base station determines, according to the capability information of the received terminal, that the terminal supports the NR PDCP protocol or supports the dual connectivity function of LTE and NR, the base station sends the NR PDCP configuration to the terminal.

The second scenario is: when the terminal accessing the base station enters an active state from an idle state, the base station receives the capability information of the terminal from the core network device, and determines, according to the capability information of the terminal, that the terminal supports the NR PDCP protocol or Support dual connectivity of LTE system and NR system.

When the terminal enters the idle state after accessing the base station, in order to reduce the system load, the base station clears the information about the terminal, including the capability information of the terminal, and the terminal reports the capability information of the terminal to the core network device when initially accessing the base station. The core network device stores the capability information reported by the terminal. Therefore, when the terminal accessing the base station enters the active state from the idle state, the base station can obtain the capability information of the terminal from the core network device. Exemplarily, in some embodiments of the present application, when the terminal accessing the base station enters the active state from the idle state, the core network device sends the terminal to the terminal by using an initial context setup request (S1). The related information is determined by the capability information carried in the S1 message after the S1 message is received by the S1 message, and the capability information indicating that the terminal supports the NR PDCP protocol or the dual connectivity function of the LTE system and the NR system is carried in the sent S1 message. After the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, the terminal transmits the NR PDCP configuration to the terminal.

In a third scenario, the terminal accesses the source base station. According to the foregoing description, when the terminal accesses the source base station, the source base station can acquire the capability information of the terminal, and therefore, when the terminal switches from the accessed source base station to the target base station, The target base station may acquire capability information of the terminal from the source base station, and the target determines, according to the capability information acquired from the source base station, that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system.

It should be understood that the above three scenarios may be used in the LTE-NR DC scenario, and in the LTE-NR DC scenario, the base station refers to the primary base station in the LTE-NR DC scenario.

302. The base station sends an NR PDCP configuration to the terminal.

Therefore, after acquiring the NR PDCP configuration, the terminal can perform configuration of the PDCP layer in the corresponding scenario. For example, in a dual-connection scenario, the terminal uses the parameters in the NR PDCP configuration to perform related PDCP configuration on the access secondary base station. In the handover scenario, the terminal uses the parameters in the NR PDCP configuration to perform related PDCP configuration on the access target base station. . The specific process will not be repeated here.

In an implementation manner of the present application, when the terminal initially accesses the primary base station, the terminal sends an indication information to the primary base station, where the indication information may carry a message in a random access procedure. Sending the indication information to the primary base station, for example, by using a preamble or a random access message 3 (RRC Connection Setup Request message or RRC Connection Re-establishment message) or a random access message 5 (RRC Connection Setup Complete message), The indication information is used to indicate that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, and the primary base station determines, according to the received indication information of the terminal, that the terminal supports the NR PDCP protocol or supports the pair of LTE and NR. When the function is connected, the base station transmits an NR PDCP configuration to the terminal.

After the base station determines that the terminal supports the NR PDCP protocol or supports the dual connectivity function of the LTE system and the NR system, the NR PDCP configuration is sent to the terminal. In the dual connectivity scenario of the LTE system and the NR system, the details of the NR PDCP configuration sent by the base station to the terminal may be referred to the process of configuring the terminal NR PDCP in the EN-DC dual connectivity scenario, and details are not described herein. It can be seen that the embodiment of the present application proposes a specific scenario in which the base station sends the NR PDCP configuration to the terminal, which improves the implementability and diversity of the solution.

In order to facilitate the implementation of the solution described in the foregoing method embodiments of the present application, related devices for implementing the above solutions are also provided below.

Referring to FIG. 13, FIG. 13 is a schematic structural diagram of an embodiment of a base station according to an embodiment of the present application. The base station is used as a primary base station described in the method embodiment of the present application, and includes: a receiving unit 101 and a sending unit 102.

The receiving unit 101 is configured to receive, by the secondary base station, a new air interface packet data convergence protocol NR PDCP configuration, and identifier information of the data radio bearer DRB corresponding to the NR PDCP configuration;

The sending unit 102 is configured to send, to the terminal, the NR PDCP configuration received by the receiving unit 101 and the identifier information of the DRB;

The base station and the secondary base station are base stations of different standards.

It can be seen that the base station shown in FIG. 13 can be used as the primary base station. If the base station and the secondary base station are in different formats, if the existing LTE DC mechanism is used, the base station may not be able to resolve the content sent by the secondary base station, thereby May cause direct discarding.
