CROSS REFERENCE OF RELATED APPLICATION

The present application claims a priority of Chinese patent application No. 202010768819.8 filed on Aug. 3, 2020, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the technical field of communication, and in particular, to a service processing method, an information indication method, a terminal and a network device.

BACKGROUND

In some communication systems, the terminal supports connected state, idle state and inactive state, and the terminal needs to release Radio Resource Control (RRC) connection in some state transitions, for example: when the terminal leaves the connected state and enters the idle state or the inactive state, the terminal needs to release the RRC connection. However, when the current terminal releases the RRC connection, all the content of the corresponding bearer(s) are released.

Referring to FIG. 2, FIG. 2 is a flowchart of a service processing method provided by an embodiment of the present disclosure, as shown in FIG. 2, it includes the following steps:

Step 201, determining, by a terminal, a service transmission mode or an indication content of an RRC release message; and

Step 202, reserving, by the terminal, a first bearer, according to the indication content or the service transmission mode, when the terminal releases an RRC connection, where the service transmission mode is a service transmission mode of the first bearer.

The foregoing service transmission mode may be indicated by the network device, or the terminal determines the service transmission mode of the first bearer according to a protocol agreement mode. In the embodiments of the present disclosure, the service transmission mode of the first bearer may include at least one of the first transmission mode or the second transmission mode, where the first transmission mode is multicast, groupcast, or broadcast, and the second transmission mode is unicast.

The indication content of the aforementioned RRC release message may include at least one of the bearer indicated to be released or the bearer indicated to be reserved, and the indication method may be explicit or implicit indication.

Reserving the first bearer, according to the aforementioned indication content, when the terminal releases the RRC connection, may include: reserving the first bearer, when the terminal releases the RRC connection, in a case that the released bearer indicated by the above indication content does not include the above first bearer, or, when the terminal releases the RRC connection, in a case that the reserved bearer indicated by the above indication content includes the above first bearer.

In the above service transmission mode, reserving the first bearer, when the terminal releases the RRC connection, may be, reserving the first bearer, when the terminal releases the RRC connection, in a case that the above service transmission mode includes a transmission mode that needs to reserve the bearer.

In addition, the aforementioned reserving the first bearer may refer to reserving all or part of content of the first bearer, for example, part of logical channels and related configurations.

In the embodiment of the present disclosure, the bearer may be a Data Resource Bearer (DRB), of course, this is not limited thereto. For example, it may also be another bearer for service transmission defined in a subsequent protocol.

In the embodiment of the present disclosure, through the above steps, the first bearer can be reserved when the RRC connection is released, so that after the terminal releases the RRC connection, it is convenient for the terminal to continue the transmission of the service corresponding to the first bearer, so as to improve the service transmission capability of the terminal, for example, continue to receive service data through the reserved bearer in the disconnected state.

As an optional implementation, the reserving the first bearer according to the service transmission mode, when the terminal releases an RRC connection, including: reserving the first bearer, when the terminal releases the RRC connection, in a case that the service transmission mode includes the first transmission mode, where the first transmission mode is multicast, groupcast, or broadcast.

In this embodiment, the first bearer can be reserved when the RRC connection is released, in a case that the service transmission mode of the first bearer includes multicast, multicast, or broadcast, so that the multicast, groupcast, or broadcast services of the terminal can continue to be received during the transitions between the connected state and the idle state/inactive state, so as to improve the service transmission capability of the terminal.

As an optional implementation, determining, by the terminal, a service transmission mode of the bearer includes: receiving, by the terminal, RRC configuration information of the first bearer, and determining a service transmission mode of the first bearer according to the RRC configuration information.

The above RRC configuration information may explicitly or implicitly indicate the service transmission mode of the first bearer. For example: the RRC configuration information indicates whether the service transmission mode of the first bearer includes the first transmission mode.

In this embodiment, when the network device can use a bearer while reserving the multicast/unicast transmission mode to transmit data, or transmit data through the multicast transmission mode, the corresponding unicast/multicast service category of the bearer is indicated in the RRC configuration information.

Optionally, the RRC configuration information indicates that the service transmission mode of the first bearer is the following one: the first transmission mode; the first transmission mode and a second transmission mode; or the second transmission mode, where the first transmission mode is multicast, groupcast, or broadcast, and the second transmission mode is unicast.

Specifically when the service transmission mode of the first bearer is the first transmission mode and the second transmission mode, the two transmission modes can transmit data of the same service, which is of course not limited.

Further, when the service transmission mode of the first bearer is the first transmission mode and the second transmission mode, reserving the first bearer may be reserving the content related to the first transmission mode, and releasing the content related to the second transmission mode in the first bearer.

In addition, when the RRC configuration message indicates that the service transmission mode of the first bearer is the second transmission mode, the first bearer may be released when the RRC connection is released.

In this embodiment, it is possible to indicate the service transmission mode of the current bearer in the bearer configuration or PDCP configuration, for example: indicate whether the first transmission mode is included, and if the first transmission mode is included, then the first bearer may establish a separate logical channel for multicast or unicast respectively, and send the service through the air interface in different transmission modes. For example, as shown in FIG. 3, bearer configurations indicate services corresponding to different bearers, where the multicast service indicates that the service transmission mode of the service includes multicast, and the unicast service indicates that the service transmission mode of the service includes unicast.

Optionally, the RLC configuration or logical channel configuration is used for explicitly indicating the service transmission mode of the RLC entity or logical channel; or in a case that no logical channel is configured for the RLC configuration, the RLC configuration implicitly indicates that the service transmission mode of the RLC entity or the logical channel is the first transmission mode.

The above-mentioned explicit indication may be indicated as the first transmission mode or the second transmission mode in the RLC configuration/logical channel configuration. If a DRB (or PDCP entity) is associated with an RLC configuration/logical channel identification of the first transmission mode. For example: as shown in FIG. 4, Bearer 1, or the RLC configuration/logical channel associated with the first transmission mode and the second transmission mode respectively, for example: as shown in FIG. 4, Bearer 2, it indicates that the service of the DRB bearer can be sent in multicast mode.

The above-mentioned implicit indication may be content such as logical channel configuration is not carried in the RLC configuration related to the first transmission mode, and a predefined fixed value is used by the configuration of the first transmission mode, such as a fixed value defined by the protocol. For example: if a DRB (or PDCP entity) is associated with at least one RLC configuration that does not have a logical channel configured, the terminal defaults that the DRB is associated with a logical channel of multicast mode, and the services of the DRB bearer can be sent in multicast mode.

As an optional implementation, the indication content indicates at least one of following: a bearer to be released, or a bearer to be reserved, where the bearer to be released may include: a bearer to be released in which a service transmission mode includes a first transmission mode, and the first transmission mode is multicast, groupcast, or broadcast.

Of course, this is not limited, for example, the network device may directly indicate the released bearer or the reserved bearer, and the terminal defaults that these bearers are the bearers of the service transmission mode including the first transmission mode.

Optionally, the method also includes: releasing a second bearer, when the terminal releases the RRC connection, in a case that the bearer to be released indicated by the indication content includes the second bearer; or releasing the second bearer, when the terminal releases the RRC connection, in a case that the bearer to be reserved indicated by the indication content does not include the second bearer; a service transmission mode of the second bearer includes the first transmission mode, where the first transmission mode is multicast, groupcast, or broadcast.

In the above embodiment, the above content can be indicated directly through the RRC release message, so that the terminal can reserve the corresponding bearer when releasing the RRC connection, thereby improving the service transmission capability of the terminal, and also avoiding the introduction of new message to save transmission resource.

Further, in the above implementation, it is also possible to avoid reserving bearers for services that do not support to be received in the disconnected state. For example, if some services of the first transmission mode do not support to be received in the disconnected state, it is possible to explicitly indicate which bearers adoptable in the first transmission mode are to be released in the RRC release message, or to explicitly indicate which bearers are to be released. Therefore, the terminal reserves bearers corresponding to other services that can be received in the disconnected state (idle/inactive state), and when the terminal releases the RRC connection, the bearer required to be released in the display notification may be performed according to the indication of the network side.

For example: if it is explicitly indicated which bearers adoptable in the first transmission mode are to be released in the RRC release message, the terminal explicitly releases the bearers. Unicast bearers not explicitly notified are performed to be released. For bearers adoptable in the first transmission mode that are not explicitly notified, the terminal only releases the logical channel and related configuration corresponding to the unicast transmission mode, and reserves the logical channel and related configuration corresponding to the first transmission mode, such as: RLC entity, MAC configuration and wireless resource.

For another example: if it is explicitly indicated which bearers are to be released in the RRC release message, the terminal explicitly releases the bearers, and the bearers not explicitly notified are reserved. If the first transmission mode can be adopted by the bearer not explicitly notified, and there is a unicast transmission mode, the terminal only releases the logical channel and related configuration corresponding to the unicast transmission mode, and reserves the logical channel and related configuration corresponding to the multicast transmission mode.

For another example: which bearers are reserved is explicitly indicated in the RRC release message, so that the terminal releases the bearers that are not indicated to be reserved, and for the bearers that are explicitly indicated to be reserved, if there is a unicast transmission mode, the terminal can only release the logical channel and related configuration corresponding to the unicast transmission mode, and reserve the logical channel and related configuration corresponding to the multicast transmission mode.

As an optional implementation, the reserving the first bearer, in a case that the service transmission mode of the first bearer includes at least one of the first transmission mode or the second transmission mode, including: reserving a configuration associated with a first logical channel in the first bearer, and releasing a configuration associated with a second logical channel in the first bearer, where the service transmission mode of the first logical channel is the first transmission mode, and the service transmission mode of the second logical channel is the second transmission mode.

Optionally, the configuration associated with the first logical channel includes at least one of following: an RLC entity associated with the first logical channel, a MAC configuration associated with the first logical channel, or a radio resource associated with the first logical channel; and/or the configuration associated with the second logical channel includes at least one of following: the RLC entity associated with the second logical channel, the MAC configuration associated with the second logical channel, or the radio resource associated with the second logical channel.

In this embodiment, when the first bearer is reserved, only the logical channel of the first transmission mode and related configuration can be reserved, and in a case that the service transmission mode also includes the second transmission mode, the logical channel of the second transmission mode and related configuration can be released. That is to say, when the terminal releases the RRC connection, only bearers (or resources) in the unicast transmission mode are performed to be released; while bearers that can transmit services through the first transmission mode are reserved.

For example: for the first transmission mode not included indicated in the RRC configuration, or the DRB including only the RLC configuration/logical channel of the second transmission mode, the DRB configuration and related resources are directly released.

Another example: for bearer in which the service transmission mode includes the first transmission mode indicated in the RRC configuration, or DRB only associated with the RLC configuration/logical channel of the first transmission mode, no operation is required when the RRC connection is released.

Another example: for bearer in which the service transmission mode includes the first transmission mode indicated in the RRC configuration, and DRB associated with both the first transmission mode and the second transmission mode at the same time, or DRB associated with RLC configuration/logical channel of the first transmission mode or the second transmission mode at the same time, when the RRC connection is released, only at least one of the RLC entity, MAC configuration, or radio resource related to the unicast transmission mode is released, while at least one of the RLC entity, MAC configuration, or radio resource related to the multicast transmission mode is reserved.

As an optional implementation, the method also includes: reporting service information corresponding to the first transmission mode to a network side, when the terminal establishes or restores the RRC connection, in a case that the service transmission mode of the first bearer includes the first transmission mode.

After the network device receives the above service information, it can know that the terminal reserves the bearer corresponding to the above first transmission mode, so that the related actions can be performed for this behavior, for example: avoiding reconfiguring the configuration content corresponding to the above service information for the terminal, or transmitting, by the network device, the service data to the terminal in the first transmission mode according to the above service information. It should be noted that, in the embodiments of the present disclosure, the behaviors of the network device are not limited.

Optionally, the service information includes at least one of following: bearer identification, logical channel identification, or, service identification.

Optionally, the service information further includes at least one of following: SDAP configuration information associated with the first transmission mode, PDCP configuration information associated with the first transmission mode, RLC configuration information associated with the first transmission mode, MAC configuration information associated with the first transmission mode, or physical PHY configuration information associated with the first transmission mode.

The above embodiment can realize the reporting the bearer identification and/or logical channel identification/service identification for the bearer of the first transmission mode currently used, when the terminal establishes or restores the RRC connection, and further, the related configuration information of bear can also be reported, for example: at least one of SDAP, PDCP, RLC, MAC, or PHY configuration information.

For example: after the RRC connection is released, if it is released to the idle state, the network side will delete all terminal context information; if it is released to the inactive state, the network side will delete part of the terminal context information; for the multicast data that the terminal in the idle state/inactive state can continue to receive, the terminal stores related entities and corresponding identification information, such as DRB identification, logical channel identification.

After the terminal establishes/restores the RRC connection, the network side may not know the identification information that the terminal has used. If the configuration on the network side conflicts with the identification information being used by the current terminal, it may cause wrong configuration of the bearer. Therefore, when the terminal establishes/restores the RRC connection, it reports the above-mentioned service for the bearer of the currently used transmission multicast service type. Therefore, after being obtained by the network device, these existing identifications can be avoided to establish other unicast service bearers for the terminal, and/or RLC entity/logical channel and related configuration information of the unicast transmission mode are added for the multicast service according to the existing identification and configuration information.

In the embodiments of the present disclosure, the terminal determines the service transmission mode or the indication content of the RRC release message; the terminal reserves the first bearer according to the indication content or the service transmission mode, when the terminal releases the RRC connection, where the service transmission mode is the service transmission mode of the first bearer. In this way, the first bearer can be reserved when the RRC connection is released, thereby improving the service transmission capability of the terminal.

Referring to FIG. 5, FIG. 5 is a flowchart of an information indication method provided by an embodiment of the present disclosure. As shown in FIG. 5, it includes the following steps: Step 501, transmitting, by a network device, an RRC message to a terminal, where an RRC indicates a service transmission mode or an indication content of an RRC release message, and the service transmission mode is a service transmission mode of a first bearer.
