Description

Method and device for processing information of condition-based mobility

Technical Field

The disclosure relates to the field of communication technologies, and in particular, to a method and a device for processing information of condition-based mobility.

Background

A dual connectivity (dual connectivity, DC) terminal device may access two cell groups, a primary cell group (master cell group, MCG) and a secondary cell group (secondary cell group, SCG), respectively, wherein the MCG corresponds to a Master Node (MN) on the network side and the SCG corresponds to a Secondary Node (SN) on the network side.

In the current system, the terminal device can perform mobility of the MCG by performing conditional handover (conditional handover, CHO), and perform mobility of the SCG by performing conditional primary-secondary cell addition (conditional PSCell addition, CPA) or conditional primary-secondary cell change (conditional PSCell change, CPC). When the terminal device successfully performs MCG mobility or performs SCG mobility, the terminal device deletes the corresponding conditional reconfiguration. However, the processing method of conditional reconfiguration is only suitable for the scenario that CHO or CPA/CPC is configured separately, and when CHO and CPA/CPC configurations exist simultaneously, it is necessary to consider how to process the conditional reconfiguration of the terminal equipment configuration after mobility is performed, so as to ensure reliability of mobility of the terminal.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for processing information of condition-based mobility, which is performed by a terminal device according to an embodiment of the present disclosure. As shown in fig. 2, the method may include, but is not limited to, the steps of:

step 201, receiving information for condition-based mobility sent by a network device, wherein the condition-based mobility includes any one of the following: conditional handover CHO and/or conditional primary secondary cell change CPC, CHO and/or conditional primary secondary cell add CPA.

Wherein, the information for the condition-based mobility may include at least one of the following: the execution condition of mobility, the configuration information of a target cell, the association relation between CHO and CPA and the association relation between CHO and CPC. The association relationship between CHO and CPA may be used to indicate that CHO and CPA are configured jointly, and the association relationship between CHO and CPC may be used to indicate that CHO and CPC are configured jointly.

Further, the information for the condition-based mobility may include condition reconfiguration information or the like, to which the present disclosure is not limited.

Alternatively, when the information for the condition-based mobility does not include the association relationship between CHO and CPA or does not include the association relationship between CHO and CPC, the network device may send the indication information to the terminal device alone to indicate the association relationship between CHO and CPA or the association relationship between CHO and CPC.

In the present disclosure, the network device may transmit information for the condition-based mobility to the terminal device, whereby the terminal device may receive and store the information for the condition-based mobility, and thereafter, the terminal device may evaluate an execution condition of the mobility, which may be executed in case the execution condition of the mobility is satisfied.

Alternatively, the network device may also send a message to the terminal device to instruct the terminal device to perform MCG mobility and/or SCG mobility. Thus, the terminal device, upon receiving the message, may perform HO and/or CPA, or perform HO and/or CPC. The message sent by the network device to the terminal device may be a radio resource control (radio resource control, RRC) reconfiguration message, or the like, which is not limited in this disclosure.

In response to performing mobility, the information for the condition-based mobility is deleted or retained, step 202.

In the present disclosure, after the terminal device performs mobility, information for the condition-based mobility may be deleted or reserved, thereby guaranteeing reliability of mobility.

In the present disclosure, deleting or retaining information for the condition-based mobility includes deleting or retaining all or part of information stored by the terminal device for the condition-based mobility.

Illustratively, deleting CHO configuration information may include deleting all or part of CHO information stored by the terminal device for condition-based mobility. Preserving CHO configuration information may include preserving all CHO configuration information stored by the end devices, or preserving CHO configuration information associated with CPAs or CPCs. Wherein the CHO configuration information is information for CHO among the information for condition-based mobility.

Furthermore, the terminal device performing MCG mobility includes the terminal device successfully accessing the target PCell. Accordingly, the terminal device performing SCG mobility includes that the terminal device successfully accesses the target PSCell.

In the present disclosure, after receiving information for condition-based mobility transmitted by a network device, a terminal device may delete or retain the information for condition-based mobility when mobility is performed. Therefore, terminal equipment configured with CHO and CPC or CHO and CPA can reasonably delete or retain information for condition-based mobility according to the execution condition of specific mobility after mobility is executed, thereby improving the reliability of the terminal mobility process.

Referring to fig. 3a, fig. 3a is a flowchart illustrating a method for processing information of condition-based mobility, which is performed by a terminal device according to an embodiment of the present disclosure. As shown in fig. 3a, the method may include, but is not limited to, the steps of:

In the disclosure, when the terminal device satisfies an execution condition for mobility of the primary cell group MCG, or when a message indicating MCG movement sent by the network device is received, mobility of the primary cell group MCG may be executed, and after mobility of the MCG is executed, CHO configuration information may be deleted to ensure that subsequent mobility is performed normally. Among them, mobility of the MCG may be CHO, handover (HO), etc., which is not limited by the present disclosure.

In the present disclosure, after performing mobility of the MCG, the terminal device may refer to a detailed description of any embodiment of the present disclosure in a manner of deleting CHO configuration information, which is not described herein again.

Alternatively, when the terminal device satisfies the execution condition for mobility of the master cell group MCG, CHO may be executed, and after CHO is executed, CHO configuration information is deleted to ensure normal operation of subsequent CHO.

Alternatively, when CHO and CPA or CPC are included in one configuration information, CHO may be considered to have an association relationship with CPA or CPC, and after the terminal device executes CHO, CHO configuration in the configuration information may be deleted.

In the present disclosure, after receiving information for condition-based mobility sent by a network device, a terminal device performs mobility of a master cell group MCG, and deletes conditional handover CHO configuration information. Therefore, the terminal equipment configured with CHO and CPC or CHO and CPA can delete CHO configuration information after executing MCG mobility, thereby improving the reliability of the terminal mobility process.

Referring to fig. 3b, fig. 3b is a flowchart illustrating a method for processing information of condition-based mobility, which is performed by a terminal device according to an embodiment of the present disclosure. As shown in fig. 3b, the method may include, but is not limited to, the steps of:

Wherein the CPA configuration information is information for CPA in the information for condition-based mobility, and the CPC configuration information is information for CPC in the information for condition-based mobility.

In the disclosure, when the terminal device satisfies the execution condition for mobility of the primary cell group MCG, or when a message indicating MCG movement sent by the network device is received, mobility of the primary cell group MCG may be executed, and CPA or CPC configuration information may be reserved, so that subsequent CPA or CPC is performed directly according to the reserved CPA or CPC configuration information. Among them, mobility of the MCG may be CHO, handover (HO), etc., which is not limited by the present disclosure.

Alternatively, when the terminal device satisfies the execution condition for mobility of the master cell group MCG, CHO may be executed, and after CHO is executed, CPA or CPC configuration information may be reserved, so that subsequent CPA or CPC is performed directly according to the reserved CPA or CPC configuration information.

Optionally, after the terminal device executes CHO, according to the association relationship between CHO and CPA in the information for condition-based mobility, the CPA associated with CHO may be determined, and the CPA configuration information may be reserved, so that the CPA may be performed directly according to the CPA associated with CHO. Or, according to the association relation between CHO and CPC in the information for condition-based mobility, determining the CPC associated with the CHO, and retaining the CPC configuration information so as to perform CPC directly according to the CPC associated with CHO. Wherein, CHO and CPA or CPC are contained in different configuration information, and there is association relation.

Alternatively, when the CHO and the CPA or CPC are included in one configuration information, the CHO may be considered to have an association relationship with the CPA or CPC, and after the terminal device executes the CHO, the CPA configuration information or CPC configuration information in the configuration information may be reserved.

Optionally, after the terminal device executes CHO, the CPA that is not associated with CHO may be determined according to the association relationship between CHO and CPA in the information for the condition-based mobility, and then the configuration information of the CPA may be deleted. Alternatively, the CPC that is not associated with CHO is determined from the association relationship between CHO and CPC in the information for the condition-based mobility, and then the configuration information of CPC may be deleted.

In the present disclosure, after receiving information for condition-based mobility sent by a network device, a terminal device reserves CPA or CPC configuration information after performing mobility of a primary cell group MCG. Therefore, the terminal equipment configured with CHO and CPC or CHO and CPA can keep CPC or CPA configuration information after the MCG mobility is executed, and the reliability of the terminal mobility process is improved.

Referring to fig. 4a, fig. 4a is a flowchart illustrating a method for processing information of condition-based mobility, which is performed by a terminal device according to an embodiment of the present disclosure. As shown in fig. 4a, the method may include, but is not limited to, the steps of:

Step 401, receiving information for condition-based mobility sent by a network device, where the condition-based mobility includes any one of the following: conditional handover CHO and/or conditional primary secondary cell change CPC, CHO and/or conditional primary secondary cell add CPA.

In the present disclosure, the specific implementation process of step 401 may refer to the detailed description of any embodiment of the present disclosure, which is not repeated herein.

Step 402, in response to performing secondary cell group SCG mobility, the CPA or CPC configuration information is deleted.

In the disclosure, when the terminal device satisfies the execution condition for the mobility of the secondary cell group SCG, or when the message indicating the SCG mobility sent by the network device is received, the mobility of the secondary cell group SCG may be executed, and after the SCG mobility is executed, the CPA or CPC configuration information may be deleted immediately, so as to ensure that the subsequent CPA or CPC is normally performed. Wherein SCG mobility may be added or changed for CPA, CPC, SCG, etc., which is not limiting of the present disclosure.
