Description

Communication method and device

The present application claims priority to Chinese Patent Application Serial No. 20 181 039 428 6.4 filed on Apr. 27, 2018, the entire disclosure of which is incorporated herein by reference.

Technical field

The embodiments of the present application relate to communication technologies, and in particular, to a communication method and device.

Background technique

In order to improve the throughput of the data transmission of the user equipment (User Equipment, UE) and reduce the signaling overhead of the core network due to the mobility of the UE, the concept of dual connectivity is introduced in the LTE system, that is, the UE can pass two The base station sends and receives data. Among the two base stations, the base station that provides the UE with the control plane connection to the core network is called the master base station (Master eNB), and the other base station that provides the UE with additional radio resources is called the secondary base station (Secondary eNB). In the 5G system, Dual connectivity technology will still be used.

In the 5G system, a new Radio Resource Control (RRC) state is added, called the RRC_INACTIVE state. RRC_INACTIVE is a type of UE that maintains connection management-CONNECTED (CM-CONNECTED) and can move within the RAN-base notification area (RNA) of the NG-RAN configuration without notifying NG. - Status of the RAN. In R15, when the UE transitions from the connected state to the inactive state, the secondary node (SN) configuration process has the following two options: Option 1: Release the cell group configuration of the SN (ieRLC/MAC/) PHY, Pscell/scell), Service Data Adaptation Protocol (SDAP)/Packet Data Convergence Protocol (PDCP) configuration of the Secondary Cell Group (SCG); Option 2 : Release all configurations of the SN.

For option 2, the bearer type change is not explicitly performed when the UE enters inactive in the existing protocol. Here, bearer type change refers to transforming an SN-related radio bearer (data bearer DRB and signaling bearer SRB) into a master node (MN) related radio bearer. The UE may maintain multiple DRBs during the inactive period, and the DRBs used when directly transmitting data in the inactive state are determined according to related services.

When the dual-connected UE moves from the connected state to the inactive state, whether or not it indicates direct transmission of the data radio bearer, the configuration of the SN needs to perform an additional two reconfiguration processes before releasing the UE to inactive. First, the SN modification process is used to complete the bearer type change by indicating the SN-related radio bearer ID list and PDCP configuration that needs to be converted into the MN-related radio bearer, and then the original SCG configuration and the related radio bearer configuration are released by using the SN release process. The SN configuration process for directly transmitting the data radio bearer when the UE transits from the connected state to the inactive state may add a corresponding indication in the RRC reconfiguration message in the SN modification process (indicating which radio interfaces are established when the connection state is allowed) Data can be transferred directly in inactive).

However, the configuration process of processing the SN when the UE moves from the connected state to the inactive state requires an additional two reconfiguration processes regardless of whether or not the radio bearer directly transmitting data is required, and the required air interface signaling overhead is large.

The first identifier list includes an identifier of a radio bearer, an identifier of a PDU session, or an identifier of a QoS flow and an identifier of a PDU session, and each bit of the first bitmap information Corresponding to one radio bearer or one QoS session of a PDU session or a PDU session, and indicating whether the corresponding radio bearer needs to perform bearer type conversion.

When the first identification list includes the identity of the radio bearer, the step 2031 is performed after step 202.

When the first identification list includes an identifier of a PDU session, or an identifier of a QoS flow and an identifier of a PDU session, the step 2032 is performed after step 202.

When each bit of the first bitmap information corresponds to one radio bearer and indicates whether the corresponding radio bearer needs to perform bearer type conversion, step 2023 is performed after step 202.

When each bit of the first bitmap information corresponds to one service quality stream or one PDU session of one PDU session, and indicates whether the corresponding radio bearer needs to perform bearer type conversion, step 202 is performed after step 202.

Step 2031: The terminal performs bearer type conversion on the radio bearer corresponding to the identifier according to the identifier of the radio bearer, the default PDCP configuration information, or the default radio bearer configuration information.

The terminal determines, according to the identifier of the radio bearer, the radio bearer that needs to be changed by the bearer type, and performs bearer type conversion on the radio bearer corresponding to the identifier according to the default PDCP configuration information or the default radio bearer configuration information, that is, the radio corresponding to the identifier The bearer is a radio bearer that is transformed into a primary cell group.

It can be understood that, when the first indication information further carries the PDCP configuration information of the radio bearer, the terminal may perform bearer type conversion on the radio bearer corresponding to the identifier according to the PDCP configuration information of the radio bearer carried by the first indication information.

Step 2032: The terminal is configured according to the identifier of the service quality flow and/or the identifier of the PDU session, the mapping relationship between the PDU session and the radio bearer, and the default radio bearer configuration information or the default packet data convergence protocol PDCP configuration information. The corresponding radio bearer is identified to perform bearer type conversion.

The mapping relationship between the PDU session and the radio bearer includes a mapping relationship between the PDU session and the service quality flow, and a mapping relationship between the service quality flow and the radio bearer, that is, the PDU session can be mapped to one or more service quality flows, and one PDU session. One or more quality of service flows may be mapped to one or more radio bearers.

That is, the terminal determines the radio bearer corresponding to the identifier according to the identifier of the PDU session and the identifier of the service quality flow, and the mapping relationship between the PDU session and the radio bearer, and corresponding to the identifier according to the default radio bearer configuration information or the default PDCP configuration information. The radio bearer performs bearer type conversion. It should be noted that the service quality flow identifier is an identifier of one or more service quality flows of the PDU session corresponding to the PDU session identifier.

Specifically, the terminal may determine the service quality flow corresponding to the PDU session according to the identifier of the PDU session, and determine the corresponding radio bearer according to the identifier of the service quality flow. That is, the radio bearer corresponding to the identifier of the service quality flow in the PDU session is determined.

Or the terminal determines the radio bearer corresponding to the identifier according to the identifier of the PDU session and the mapping relationship between the PDU session and the radio bearer, and performs bearer type transformation on the radio bearer corresponding to the identifier according to the default radio bearer configuration information or the default PDCP configuration information. .

The PDU session is configured to a plurality of QoS flows, that is, the PDU session has a mapping relationship with the QoS flow, and the QoS flow has a mapping relationship with the radio bearer. For example, A PDU session (ID=2) of the connected terminal is configured with 4 QoS flows, and the QoS flow IDs are 1, 2, 3, and 4, respectively. The network device in the access network accessed by the terminal maps the four QoS flows to the radio bearer ID of the terminal according to its policy configuration to be 3, 4, 6, and 7, respectively. Specifically, the QoS flow 1 maps to the radio bearer. 3. QoS flow 2 is mapped to radio bearer 4, QoS flow 3 is mapped to radio bearer 6, and QoS flow 4 is mapped to radio bearer 7. The foregoing example further illustrates that, when the first identifier list includes the PDU session identifier is 2, and the identifier of the associated QoS flow is 1, the terminal identifies the identifier of the PDU session and the identifier of the service quality flow. And the mapping relationship between the PDU session and the radio bearer determines the corresponding radio bearer, and the radio bearer corresponding to the QoS flow 1 in the PDU session is the radio bearer 3, and the terminal according to the default radio bearer configuration information or the default packet data convergence protocol PDCP The configuration information performs bearer type conversion on the radio bearer 3.

Transform.

Each of the first bitmap information corresponds to one radio bearer, and uses 0 or 1 to indicate whether the corresponding radio bearer needs to perform bearer type conversion. For example, using 0 indicates that the corresponding radio bearer does not need to perform bearer type conversion. Use 1 to indicate that the corresponding radio bearer needs to perform bearer type conversion, or use 0 to indicate that the corresponding radio bearer needs to perform bearer type conversion, and use 1 to indicate that the corresponding radio bearer does not need to perform bearer type conversion. The radio bearer that needs to perform the bearer type conversion may be determined according to the first bitmap information, and bearer type conversion is performed on the corresponding radio bearer according to the default radio bearer configuration information or the default packet data convergence protocol PDCP configuration information.

Step 2034: The terminal determines, according to the first bitmap information and the mapping relationship between the PDU session and the radio bearer, the radio bearer that needs to perform bearer type conversion, and according to the default radio bearer configuration information or the default packet data convergence protocol PDCP. The configuration information performs bearer type conversion on the radio bearer.

Each bit of the first bitmap information corresponds to a service quality flow or a PDU session of a PDU session, and uses 0 or 1 to indicate whether a service quality flow of a PDU session or a radio bearer corresponding to a PDU session needs to be carried. The type conversion, for example, uses 0 to indicate that the corresponding radio bearer does not need to perform bearer type conversion, and uses 1 to indicate that the corresponding radio bearer needs to perform bearer type conversion.

When each bit of the first bitmap information corresponds to a service quality stream of a PDU session, the terminal may determine the corresponding radio bearer according to the mapping relationship between the PDU session and the radio bearer. Specifically, the first bitmap information is 1011. The first bit of the first bitmap information corresponds to QoS flow 1, the second bit corresponds to QoS flow 2, and so on, and the fourth bit corresponds to QoS flow 4, and then according to the mapping relationship between the PDU session and the radio bearer, step 2032 For example, the QoS flow 1 is mapped to the radio bearer 3, the QoS flow 2 is mapped to the radio bearer 4, the QoS flow 3 is mapped to the radio bearer 6 and the QoS flow 4 is mapped to the radio bearer 7, and the first bitmap information can be determined according to the first bitmap information. The bearer type transformed radio bearers are radio bearers 3, 6, and 7.

When each bit of the first bitmap information corresponds to one PDU session, the terminal may determine the corresponding radio bearer according to the mapping relationship between the PDU session and the radio bearer. Specifically, the first bitmap information is 0100, and the first bitmap is The first bit of information corresponds to the PDU session (ID=1), the second bit corresponds to the PDU session (ID=2), and so on, the fourth bit corresponds to the PDU session (ID=4), and then according to the PDU session and the radio bearer Mapping relationship, with the example of step 2032, QoS flow radio bearer 3 of PDU session (ID=2), QoS flow 2 of PDU session (ID=2) mapped to radio bearer 4, QoS flow of PDU session (ID=2) 3 QoS flow 4 mapped to the radio bearer 6 and the PDU session (ID=2) is mapped to the radio bearer 7, and the radio bearer that needs to perform bearer type conversion can be determined as the radio bearer 3, 4, 6 according to the first bitmap information. The bearer type conversion is required for the radio bearers corresponding to all the QoS flows of the PDU session.

After determining, according to the first bitmap information, the radio bearer that needs to perform the bearer type conversion, the bearer type is changed according to the default radio bearer configuration information or the default packet data convergence protocol PDCP configuration information.
