This application claims a priority to Chinese Patent Application No. 202111202901.5 filed on Oct. 15, 2021 and a priority to Chinese Patent Application No. 202111232756.5 filed on Oct. 22, 2021, the disclosures of which are incorporated in their entirety by reference herein.
The present disclosure relates to the field of communications technologies, and in particular, to an information processing method, an information processing apparatus, and a readable storage medium.
Direct communication refers to a manner in which neighboring terminal equipments perform data transmission by using a direct communication link (also referred to as SL (sidelink). The direct communication link is also referred to as a bypass. The wireless interface corresponding to the Sidelink is referred to as a direct communication interface, which is also referred to as a Sidelink interface or a bypass interface. In order to improve user experience, a direct communication interface SL DRX (SL Discontinuous Reception) mechanism and/or a SL DTX (SL Discontinuous Transmission) mechanism are introduced. For a SL receiving end, SL DRX is used; correspondingly, for a SL sending end, SL DTX is used.
For a traditional handover scenario, a source base station sends a Handover Request (HANDOVER REQUEST) message to the target base station, the handover request message carries an RRC (Radio Resource Control) Context of a terminal equipment to be handed over. Specifically, the content of the RRC Context is defined in HandoverPreparationInformation (Handover Preparation Information), and the HandoverPreparationInformation includes RRC configuration information of the terminal equipment to be handed over, which is configured by the source base station.
In case of SL unicast, SL DRX/DTX configuration used by a connected-state terminal equipment for the source base station may be carried in the HandoverPreparationInformation, and the target base station may determine the SL DRX and/or DTX configuration of the terminal equipment to be handed over under the target base station according to indication in the HandoverPreparationInformation without enhancement.
However, for the SL groupcast/broadcast, the SL DRX/DTX configuration determined by the connected-state terminal equipment is not configured by the source base station. In this case, how the target base station determines whether the terminal equipment needs to use the SL DRX/DTX configuration and which SL DRX/DTX configuration is specifically used is a technical problem to be solved.

Referring to
Step 101: When a first network equipment determines that a terminal equipment needs to perform handover, the first network equipment sends a first message to a second network equipment.
The first network equipment may be a base station, a Central Unit (CU), or the like.
In the embodiments of the present disclosure, when the terminal equipment has groupcast communication on the sidelink interface, the first message includes assistant information related to SL DRX configuration and/or the SL DTX configuration corresponding to the groupcast communication on the sidelink interface of the terminal equipment; and/or when the terminal equipment has broadcast communication on the sidelink interface, the first message includes assistant information related to SL DRX configuration and/or the SL DTX configuration corresponding to the broadcast communication of the sidelink interface of the terminal equipment.
The method in which the first network equipment determines whether the terminal equipment needs to perform handover may be a determination method in the related art. Determining whether the terminal equipment has groupcast communication and/or broadcast communication on the SL interface by the first network equipment may use an existing mechanism, for example, the first network equipment may determine whether the terminal equipment has groupcast communication and/or broadcast communication, and determine an L2 target address corresponding to groupcast and/or broadcast, according to sidelinkUEinformation (Sidelink UE information) reported by the terminal equipment.
In an embodiment of the present disclosure, the assistant information includes one or more of the following assistant information:
The foregoing (1)-(3) and (5)-(8) may be obtained by the first network equipment from the terminal equipment. Specifically, the terminal equipment may reuse an existing RRC (Radio Resource Control) signaling (for example, SidelinkUEInformation or UEAssistantantInformation) to report the foregoing information, or may introduce new RRC signaling to report the foregoing information.
In the embodiments of the present disclosure, when the first network equipment determines that the terminal equipment needs to perform handover, the first network equipment sends the first message to the second network equipment, where the first message includes the assistant information related to SL DRX configuration and/or SL DTX configuration related corresponding to the groupcast communication and/or the broadcast communication of the sidelink interface of the terminal equipment, so that the second network equipment may obtain the SL DRX configuration and/or the SL DTX configuration used by the terminal equipment for the sidelink interface under the first network equipment, and perform corresponding configuration on the terminal equipment. Therefore, by using the embodiments of the present disclosure, the second network equipment in a handover scenario can determine whether the SL DRX/SL DTX needs to be configured for the terminal equipment to be handed over and how to configure the SL DRX/SL DTX, thereby ensuring power saving of the sidelink interface of the terminal equipment in the handover scenario.
In addition, for a purpose of enabling the second network equipment to configure the configuration to the terminal equipment through the RRC reconfiguration process of the first network equipment, the first network equipment may further receive a second message sent by the second network equipment on the basis of the foregoing embodiments, where the second message includes one or more of the following:
The first network equipment is a source network equipment of the terminal equipment, and the second network equipment is a target network equipment of the terminal equipment. The second network equipment may be a base station or the like.
The indication information includes one or more of the following:
Referring to
Step 201: a second network equipment receives a first message sent by a first network equipment, where the first message is sent by the first network equipment when the first network equipment determines that the terminal equipment needs to perform handover.
Step 202: the second network equipment performs SL DRX configuration and/or SL DTX configuration on groupcast communication and/or broadcast communication of the sidelink interface of the terminal equipment according to the first message.
When the terminal equipment has groupcast communication on the sidelink interface, the first message includes assistant information related to SL DRX configuration and/or the SL DTX configuration corresponding to the groupcast communication of the sidelink interface; and/or when the terminal equipment has broadcast communication on the sidelink interface, the first message includes assistant information related to SL DRX configuration and/or the SL DTX configuration corresponding to the broadcast communication of the sidelink interface.
The first network equipment is a source network equipment of the terminal equipment, and the second network equipment is a target network equipment of the terminal equipment. The second network equipment may be a base station or the like.
A meaning of the assistant information may be obtained by referring to the description of the foregoing embodiments.
In the step 202, according to different contents included in the assistant information, the second device may have different manners to determine whether to perform SL DRX configuration and/or SL DTX configuration on groupcast communication and/or broadcast communication of the sidelink interface of the terminal equipment, and how to configure.
For example, when the assistant information includes the indication information about that the SL DRX configuration and/or the SL DTX configuration is used for the L2 target address of the sidelink interface of the terminal equipment, the second network equipment determines that the SL DRX configuration and/or the SL DTX configuration need to be performed. In this case, the second device may perform SL DRX configuration and/or SL DTX configuration on the groupcast communication and/or the broadcast communication of the sidelink interface of the terminal equipment according to the SL DRX configuration and/or the SL DTX configuration indicated in the assistant information.
For example, when the assistant information includes the indication information about that the SL DRX configuration and/or the SL DTX configuration is used for the combination of the L2 target address and the SL transmission mode of the sidelink interface of the terminal equipment, the second network equipment determines that the SL DRX configuration and/or the SL DTX configuration needs to be performed for the combination of the L2 target address and the SL transmission mode of the sidelink interface of the terminal equipment. In this case, the second device may perform SL DRX configuration and/or SL DTX configuration on the groupcast communication and/or the broadcast communication of the sidelink interface of the terminal equipment according to the SL DRX configuration and/or the SL DTX configuration used for the combination indicated in the assistant information.
For example, when the assistant information includes the TX profile corresponding to the sidelink interface of the terminal equipment, the second network equipment determines, based on the TX profile corresponding to the sidelink interface of the terminal equipment, whether the SL DRX configuration and/or the SL DTX configuration needs to be performed on the terminal equipment. It is assumed that the TX profile includes a certain L2 address, and then the second device may perform SL DRX configuration and/or SL DTX configuration on the L2 address.
For example, when the assistant information includes the correspondence between the QoS profile and the SL DRX configuration and/or the correspondence between the QoS profile and the SL DTX configuration configured in the SIB of the first network equipment, the second network equipment performs the SL DRX configuration and/or the SL DTX configuration according to the correspondence between the QoS profile and the SL DRX configuration configured in the SIB of the first network equipment.
For example, when the assistant information includes the SL DRX configuration and/or the SL DTX configuration corresponding to the L2 target address of the sidelink interface of the terminal equipment, the second network equipment performs the SL DRX configuration and/or the SL DTX configuration according to the SL DRX configuration and/or the SL DTX configuration corresponding to the L2 target address of the sidelink interface of the terminal equipment.
For example, when the assistant information includes the SL DRX configuration and/or the SL DTX configuration corresponding to the combination of the L2 target address and the SL transmission mode of the sidelink interface of the terminal equipment, the second network equipment performs the SL DRX configuration and/or the SL DTX configuration according to the SL DRX configuration and/or the SL DTX configuration corresponding to the combination of the L2 target address and the SL transmission mode of the sidelink interface of the terminal equipment.
For example, when the assistant information includes the correspondence between the QoS profile and the SL DRX configuration and/or the correspondence between the QoS profile and the SL DTX configuration under the L2 target address of the sidelink interface of the terminal equipment, the second network equipment configures the SL DRX configuration and/or the SL DTX configuration corresponding to each QoS profile according to the correspondence.
For example, when the assistant information includes the correspondence between the QoS profile and the SL DRX configuration and/or the correspondence between the QoS profile and the SL DTX configuration under the combination of the L2 target address of the sidelink interface of the terminal equipment and the SL transmission mode, the second network equipment configures the SL DRX configuration and/or the SL DTX configuration corresponding to each QoS profile according to the correspondence.
When the assistance information received by the second network equipment includes a plurality of pieces of information, the second network equipment may determine, based on any one of the plurality of pieces of information, whether to perform SL DRX configuration and/or SL DTX configuration, and how to perform SL DRX configuration and/or SL DTX configuration. Optionally, the second network equipment may further perform, with reference to a preset policy, a final decision based on a determination result obtained by using the plurality of pieces of information. In the embodiments of the present disclosure, there is no limitation on how the second network equipment makes a decision, as long as the second network equipment can obtain the final decision.
In the embodiments of the present disclosure, when the first network equipment determines that the terminal equipment needs to perform handover, the first network equipment sends a first message to the second network equipment, where the first message includes the assistant information related to SL DRX configuration and/or SL DTX configuration corresponding to the groupcast communication and/or the broadcast communication of the sidelink interface of the terminal equipment, so that the second network equipment may obtain the SL DRX configuration and/or the SL DTX configuration of the terminal equipment, and perform corresponding configuration on the terminal equipment. Therefore, by using the embodiments of the present disclosure, the second network equipment can determine whether the SL DRX/SL DTX needs to be configured for the terminal equipment to be handed over in a handover scenario, and how to configure the SL DRX/SL DTX, thereby ensuring power saving of the sidelink interface of the terminal equipment in the handover scenario.
In addition, for a purpose of enabling the second network equipment to configure the configuration to the terminal equipment through the RRC reconfiguration process of the first network equipment, the second network equipment may further send the second message to the first network equipment on the basis of the foregoing embodiments, where the second message includes one or more of the following:
The indication information includes one or more of the following:
Referring to
Step 301: the terminal equipment sends, to the first network equipment, the assistant information related to the SL DRX configuration and/or the SL DTX configuration corresponding to the groupcast communication of the sidelink interface; and/or, the terminal equipment sends, to the first network equipment, the assistant information related to the SL DRX configuration and/or the SL DTX configuration corresponding to the broadcast communication of the sidelink interface.
The assistant information includes one or more of the following:
In this embodiment of the present disclosure, the terminal equipment sends the first message to the first network equipment, so that when the first network equipment determines that the terminal equipment needs to perform handover, the first network equipment sends the first message to the second network equipment, where the first message includes the assistant information related to SL DRX configuration and/or SL DTX configuration corresponding to the groupcast communication and/or the broadcast communication of the sidelink interface of the terminal equipment, so that the second network equipment may obtain the SL DRX configuration and/or the SL DTX configuration of the terminal equipment, and perform corresponding configuration on the terminal equipment. Therefore, by using the embodiments of the present disclosure, the second network equipment can determine whether the SL DRX/SL DTX needs to be configured for the terminal equipment to be handed over in a handover scenario and how to configure the SL DRX/SL DTX, thereby ensuring power saving of the sidelink interface of the terminal equipment in the handover scenario.
The implementation process of the information processing method in the embodiments of the present disclosure will be described in detail below with reference to specific embodiments. The first network equipment is the source base station and the second network equipment is the target base station.
In the embodiments of the present disclosure, the source base station performs a handover decision for the terminal equipment. When the terminal equipment needs to perform handover, and if the terminal equipment has groupcast communication and/or broadcast communication in the SL interface and when the source base station sends a handover request message to the target base station, the handover request message needs to carry the assistant information related to the SL DRX configuration and/or the assistant information related to the SL DTX configuration corresponding to the groupcast and/or broadcast of the SL interface of the terminal equipment.
Referring to
Step 401: a terminal equipment reports the assistant information.
This step is an optional step. If the source base station may determine whether the SL DRX configuration/the SLDTX configuration are used for the L2 target address or the combination of the L2 target address and the SL transmission mode of the SL interface of the terminal equipment, this step may be omitted.
The specific determination manner of the source base station may be as follows: the source base station determines, according to a SUI (sidelink UE information, SidelinkUEinformation) reported by the terminal equipment, an L2 target address or a combination of an L2 target address and an SL transmission mode corresponding to the SL groupcast and/or SL broadcast of the terminal equipment. Then, the source base station determines a certain (or specific) L2 target address of the SL interface of the terminal equipment according to the TX profile (Tx profile indicates whether each L2 target address or a combination of the L2 target address and the SL transmission mode uses the SL DRX configuration/SL DTX configuration), or whether the combination of the L2 target address and the SL transmission mode corresponding to the SL interface of the terminal equipment uses the SL DRX configuration/SL DTX configuration.
If the source base station cannot determine whether a combination of the specific L2 target address or the combination of the L2 target address and the SL transmission mode of the SL interface uses the SL DRX configuration/SL DTX configuration, a terminal equipment reporting mechanism needs to be introduced, and the terminal equipment directly reports, to the source base station, indication information about whether the specific L2 target address or a combination of the L2 target address and the SL transmission mode of the SL interface of the terminal equipment uses the SL DRX configuration/SL DTX configuration. Specifically, the reporting of the assistant information may reuse an existing RRC signaling, or a new RRC signaling may be introduced. If the existing RRC signaling is reused, for example, sidelinkUEinformation may be reused.
Step 402: the source base station performs a handover decision on the terminal equipment. If it is determined that the terminal equipment needs to perform the handover, a handover request message is sent to the target base station.
The source base station performs the handover decision on the terminal equipment, and if the terminal equipment has groupcast communication and/or broadcast communication on the SL interface, then when the source base station sends a handover request message to the target base station, the handover request message needs to carry the assistant information related to the DRX configuration and/or the DTX configuration corresponding to groupcast and/or broadcast of the SL interface of the terminal equipment.
Determining whether the terminal equipment has the groupcast communication and/or broadcast communication on the SL interface by the source base station may use an existing mechanism, for example, the base station may determine the L2 target address corresponding to the groupcast and/or broadcast by using SidelinkUEInformation reported by the terminal equipment.
The contents of the assistant information may be indication information of whether the L2 target address of the SL interface of the terminal equipment uses the SL DRX configuration and/or the SL DTX configuration, or indication information about whether the combination of the L2 target address of the SL interface of the terminal equipment and the SL transmission mode uses the SL DRX configuration and/or the SL DTX configuration.

After the target base station determines, according to the assistant information, whether the SL DRX/DTX configuration needs to be performed for the SL groupcast and/or broadcast communication of the terminal equipment, the method further includes: notifying, by the target base station to the source base station through the interface between base stations, indication information of the SL DRX/SL DTX configuration performed for the SL groupcast and/or broadcast communication of the terminal equipment.
Specifically, the indication information of the SL DRX/SL DTX configuration transmitted in the interface may include one or more of the following:
Step 404: the source base station performs RRC reconfiguration to the terminal equipment.

The RRC reconfiguration signaling includes the Sidelink SL DRX/SL DTX configuration of the terminal equipment determined in step 403.
Referring to
Step 501: a terminal equipment reports the assistant information.
Specifically, the assistant information may be a TX profile obtained by the terminal equipment from a higher layer (an AS above a protocol layer, for example, a V2X layer). The content of the Tx profile may be one of the following:
Specifically, the reporting of the assistant information may reuse an existing RRC signaling, or a new RRC signaling may be introduced. If the existing RRC signaling is reused, for example, sidelinkUEInformation may be reused.
Step 502: the source base station performs a handover decision on the terminal equipment, and if it is determined that the terminal equipment needs to perform the handover, the source base station sends a handover request message to the target base station.
The source base station performs a handover decision on the terminal equipment, and if the terminal equipment has groupcast and/or broadcast communication on the SL interface, then when the source base station sends the handover request message to the target base station, the handover request message needs to carry the assistant information related to the DRX configuration and/or the DTX configuration corresponding to the groupcast and/or broadcast of the SL interface of the terminal equipment.
Determining whether the terminal equipment has groupcast and/or broadcast communication on the SL interface by the source base station may use an existing mechanism, for example, the base station may determine the L2 target address corresponding to the groupcast and/or broadcast by using SidelinkUEInformation reported by the terminal equipment.

After the target base station determines, according to the assistant information, whether the SL DRX/DTX configuration needs to be performed for the SL groupcast and/or broadcast communication of the terminal equipment, the method further includes: notifying, by the target base station to the source base station through the interface between base stations, indication information of the SL DRX/SL DTX configuration performed for the SL groupcast and/or broadcast communication of the terminal equipment.
Specifically, the indication information of the SL DRX/SL DTX configuration transmitted in the interface may include one or more of the following:

The RRC reconfiguration message includes the Sidelink SL DRX configuration/SL DTX configuration of the terminal equipment determined in step 503.
Referring to
Step 601: the source base station performs a handover decision on the terminal equipment, and if it is determined that the terminal equipment needs to perform the handover, the source base station sends a handover request message to the target base station.
The source base station performs the handover decision on the terminal equipment, and if the terminal equipment has groupcast and/or broadcast communication on the SL interface, then when the source base station sends the handover request message to the target base station, the handover request message needs to carry the assistant information related to the DRX configuration and/or the DTX configuration corresponding to the groupcast and/or the broadcast of the SL interface of the terminal equipment.
Determining whether the terminal equipment has groupcast and/or broadcast communication on the SL interface by the source base station may use an existing mechanism, for example, the base station may determine the L2 target address corresponding to the groupcast and/or broadcast by using SidelinkUEInformation reported by the terminal equipment.
The handover request message needs to carry the assistant information, and specifically, the content of the assistant information may be correspondence between a Quality of Service (QOS) profile and SL DRX configuration and/or correspondence between the QoS profile and the SL DTX configuration configured in a SIB of the source base station.

It should be noted that the division of the units in the embodiments of the present disclosure is schematic and is merely a logical function division, and there may be other division manners in actual implementation. In addition, functional units in the embodiments of the present disclosure may be integrated into one processing unit, or each of the units may exist alone physically, or two or more units are integrated into one unit. The integrated unit may be implemented in a form of hardware, or may be implemented in a form of a software functional unit.
When the integrated unit is implemented in the form of a software functional unit and sold or used as an independent product, the integrated unit may be stored in a processor-readable storage medium. Based on such understanding, an essential part, or a part contributing to the related art, or some or all of the technical solutions of the present disclosure may be embodied in the form of a software product, and the computer software product is stored in a storage medium and includes several instructions for causing a computer device (which may be a personal computer, a server, or a network equipment, etc.) or a processor to execute all or part of the steps of the method described in the embodiments of the present disclosure. The foregoing storage medium includes: any medium that can store program codes, such as a USB flash drive, a removable hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.
An embodiment of the present disclosure further provides a readable storage medium, a program is stored on the readable storage medium, and when the program is executed by the processor, each process of the foregoing information processing method embodiment is implemented, and the same technical effect can be achieved. The readable storage medium may be any usable medium or data storage device accessible by the processor, including but not limited to a magnetic memory (for example, a floppy disk, a hard disk, a magnetic tape, a magneto-optical disk (MO), etc.), an optical memory (for example, CD, DVD, BD, HVD, etc.), and a semiconductor memory (for example, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (Electrically EPROM, EEPROM), a non-volatile memory (NAND Flash), a solid state drive (SSD), etc.
It should be noted that, in this specification, the terms “include”, “comprise” or any other variations thereof are intended to cover a non-exclusive inclusion, so that a process, a method, an article, or an apparatus that includes a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to the process, method, article, or apparatus. In the absence of more restrictions, an element after a statement “including” does not preclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.
Through the description of the foregoing embodiments, a person skilled in the art may clearly understand that the method in the foregoing embodiment may be implemented by means of software plus a necessary general hardware platform, or of course, may also be implemented by hardware, but in many cases, the former is a better implementation. According to such an understanding, the essential part, or a part contributing to the related art, of the technical solutions of the present disclosure may be embodied in the form of a software product, and the computer software product is stored in a storage medium (for example, a ROM/RAM, a magnetic disk, or an optical disk), and includes several instructions for enabling a terminal equipment (which may be a mobile phone, a computer, a server, an air conditioner, or a network equipment) to perform the method described in the embodiments of the present disclosure.
It should be noted that, it should be understood that the division of each of the foregoing modules is merely a division of logical functions, and during actual implementation, all or some of the foregoing modules may be integrated into one physical entity, or may be physically separated. The modules may all be implemented in a form of software invoked by a processing element, or may all be implemented in a form of hardware: or some modules may be implemented in a form of invoking software by using a processing element, and some modules are implemented in a form of hardware. For example, the determining module may be a separately established processing element, or may be integrated in a certain chip of the foregoing apparatus, and in addition, the determining module may be stored in a memory of the foregoing apparatus in a form of program code, and a certain processing element of the foregoing apparatus invokes and executes the function of the foregoing determining module. Other modules may be implemented similarly. In addition, all or some of these modules may be integrated together, or may be implemented independently. The processing element described herein may be an integrated circuit with signal processing capability. In an implementation process, each step of the foregoing method or the foregoing modules may be completed by using an integrated logic circuit of hardware in the processor element or an instruction in a form of software.
For example, each module, unit, subunit, or submodule may be one or more integrated circuits configured to implement the foregoing method, for example, one or more application specific integrated circuits (ASIC), or one or more microprocessors (DSP), or one or more field programmable gate arrays (FPGA). For another example, when a certain module is implemented in a form of scheduling program code by using a processing element, the processing element may be a general-purpose processor, for example, a central processing unit (CPU) or another processor that can invoke the program code. For another example, these modules may be integrated together and implemented in a form of a system on a chip (SOC).
The terms “first”, “second”, and the like in the specification and claims of the present disclosure are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way may be interchanged where appropriate, so that the embodiments of the present disclosure described herein are implemented in an order other than those illustrated or described herein. In addition, the terms “include” and “have” and any variations thereof are intended to cover non-exclusive inclusion, for example, processes, methods, systems, products, or devices that include a series of steps or units are not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not expressly listed or inherent to these processes, methods, products, or devices. In addition, the description and claims use “and/or” to refer to at least one of the connected objects, such as A and/or B and/or C, indicating that A exists, B exits, C exists, and both A and B exist, both B and C exist, both A and C exist, and all A, B and C exist. Similarly, the use of “at least one of A and B” in this specification and the claims should be understood as “A alone, B alone, or both A and B”.
The embodiments of the present disclosure are described above with reference to the accompanying drawings, but the present disclosure is not limited to the above specific embodiments, and the above specific embodiments are merely illustrative and not restrictive, and a person of ordinary skill in the art can also make many forms without departing from the spirit of the present disclosure and the scope of protection of the claims, and all fall within the protection of the present disclosure.
