The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.
Device-to-Device communication (D2D) is a Sidelink transmission technology (Sidelink, SL) based on D2D, and unlike the conventional cellular system in which communication data is received or transmitted through a base station, the car networking system adopts a terminal-to-terminal direct communication mode, which has higher spectral efficiency and lower transmission delay. The technology of vehicle networking is standardized in the Third Generation partnership Project (3 GPP) release 14(Rel-14), defining two modes of transmission: mode a and mode B.
Mode A: referring to fig. 1A, transmission resources of a terminal are allocated by a base station, and the terminal performs data transmission on a sidelink according to the resources allocated by the base station; the base station can allocate resources for single transmission to the terminal and can also allocate resources for semi-static transmission to the terminal; the base station allocates the side link transmission resource through Downlink (DL) control signaling.
And (3) mode B: referring to fig. 1B, the terminal uses a transmission mode of listening (sensing) and reserving (reserving). The terminal acquires an available transmission resource set in the resource pool in an interception mode, and randomly selects one resource from the set to transmit data. Because the service in the car networking system has a periodic characteristic, the terminal generally adopts a semi-static transmission mode, that is, after the terminal selects one transmission resource, the resource is continuously used in a plurality of transmission cycles, so that the probability of resource reselection and resource conflict is reduced. The terminal can carry the information of the reserved secondary transmission resource in the control information transmitted this time, so that other terminals can judge whether the resource is reserved and used by the user by detecting the control information of the user, and the purpose of reducing resource conflict is achieved.
In 3GPP, D2D was studied in several different stages, among which:
device-to-device communication in release 12/13(Rel-12/13) is a study conducted for the context of Proximity based Service (ProSe), mainly for public safety class traffic. The configuration of the discontinuous transmission and reception parameters is based on pre-configuration, or network configuration based on timing reference signals propagated by the terminal UE, and data transmission and reception between UEs can be realized only if the UEs communicating with each other are configured with the same discontinuous transmission and reception parameters, that is, based on the same pre-configuration and network configuration, the UEs have the same configuration for the discontinuous transmission and reception parameters.
In version 14/15(Rel-14/15), research was conducted in an internet of vehicles system, i.e., a scenario of Vehicle-to-Vehicle communication from a new air interface NR-Vehicle to another device (V2X), which is mainly oriented to a traffic of Vehicle-to-Vehicle and Vehicle-to-Vehicle communication moving at a relatively high speed, wherein, in the internet of vehicles environment, a Vehicle-type terminal has a fixed power input, so no consideration is given to the configuration of a reception mode in discontinuous transmission and reception, i.e., it is assumed that the Vehicle-type terminal is always in a continuous reception state; however, the handheld terminal does not implement a data receiving function in the environment of the internet of vehicles, but is in a one-way sending state, and completes the one-way transmission of data by means of the receiving function of the vehicle terminal.
In release 14(Rel-14), research is conducted on a scenario where a wearable device accesses a network through a mobile phone, and the scenario is mainly directed to low moving speed and low power access. In the scene of the wearable device, a discontinuous data receiving and transmitting mode used in communication between the wearable device and the mobile phone is researched, and the use mode is as follows: and the base station configures discontinuous receiving and transmitting parameters of the remote UE through the relay UE. After receiving the configured discontinuous transceiving parameters of the base Station, the remote UE communicates with the relay UE by using the discontinuous transceiving parameters, and the terminal according to the embodiment of the present invention may include various handheld devices, vehicle-mounted devices, computing devices, or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), a Mobile Station (MS), a terminal device (terminal device), a Roadside Unit (RSU), and the like. For convenience of description, the above-mentioned terminals are collectively referred to as terminals.
Connection management for D2D/V2X:
in the ProSe system, 3GPP defines (PC5-Signaling, PC5-S) protocols based on connection management for terminal-to-terminal including, but not limited to:
-establishment and release of a connection;
-security parameter configuration of the connection;
-channel quality monitoring of the connection;
in LTE-V2X, since broadcast services are mainly targeted and there is no concept of connection between terminals, 3GPP does not define a connection management mechanism, and in NR-V2X, since unicast and multicast services need to be considered and there is a concept of connection between terminals, the design of how to perform the connection management mechanism, including the scheme design of using PC5-Signaling for management in the non-access stratum and/or using PC5-RRC Signaling for management in the access stratum, is a problem to be solved.
In view of the above problems, the present application provides a configuration management method for multicast services to implement configuration management of communication connection between terminals. The following is a detailed description.
Referring to fig. 2A, fig. 2A is a configuration management method for multicast service, which is applied to a first terminal in a communication system, such as an LTE-V2X system, according to an embodiment of the present invention, and the method includes:
step 201, the first terminal sends first configuration information for a first multicast service to at least one second terminal, where the first configuration information is used to configure a target second terminal in the at least one second terminal.
The first multicast service is associated with the at least one second terminal, and a target second terminal of the first multicast service needs to be configured according to the first configuration information, and a second terminal of the at least one second terminal except the target second terminal needs to be configured according to configuration information different from the first configuration information, for example, the second terminal a needs to be configured through the second configuration information, and the second terminal B needs to be configured through the third configuration information, and the like, which is not limited herein.
The first multicast service may be, for example, a video service, an audio service, and the like, which is not limited herein.
The first configuration information includes various kinds of indication information, where the first configuration information includes, but is not limited to, measurement class configuration information, security encryption class configuration information, configuration information for a Protocol stack, and the like (for example, configuration information of a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer).
When a target second terminal in the at least one second terminal receives the first configuration information, configuration control operation is performed according to the first configuration information, so as to realize transmission of a first multicast service between the first terminal and the target second terminal.
It can be seen that, in the embodiment of the present invention, a first terminal sends first configuration information for a first multicast service to at least one second terminal, where the first configuration information is used to configure a target second terminal in the at least one second terminal. Therefore, when the first terminal sends the multicast service, the first terminal can individually configure the target second terminal in at least one second terminal, and does not need to collectively configure the same configuration for all the second terminals, so that the configuration from a single terminal to a single terminal is realized, the flexibility and pertinence of the terminal configuration are favorably improved, and the configuration management efficiency is improved.
In one possible example, the first multicast service is associated with a plurality of pieces of configuration information of a plurality of terminals in a device group, the plurality of pieces of configuration information include the first configuration information, any two pieces of configuration information in the plurality of pieces of configuration information are different from each other, and the device group is a device group of the first multicast service.
The device group comprises a plurality of terminals associated with the first multicast service, and the plurality of terminals comprise the at least one second terminal.
The configuration information is different configuration information for different terminals in the plurality of terminals, and includes, for example, the second configuration information and the third configuration information.
As can be seen, in this example, the first terminal may send the multiple pieces of configuration information associated with the first multicast service to different terminals in the device group for configuration, so that flexibility of configuration is improved, and the first multicast service is played in the device group.
In one possible example, the at least one second terminal comprises one second terminal; the first configuration information is transmitted over a unicast connection.
The unicast connection transmission is point-to-point connection transmission between the first terminal and the second terminal, that is, the first configuration information is transmitted from the first terminal to the second terminal through the unicast connection.
As can be seen, in this example, the first terminal sends the first configuration information to the second terminal through unicast connection transmission, which can improve the pertinence of the first configuration information, so that the second terminal can timely know the relevance between the first configuration information and itself.
In this possible example, the unicast connection transmission comprises at least one of the following transmission modes:
transmitting via a layer 2 address or a media access control layer address associated with the identity of the first terminal and/or the identity of the target second terminal;
transmitting via a unicast data bearer and/or a signaling bearer with the first terminal and the target second terminal.
Layer 2 includes, among other things, the MAC layer, and the physical layer.
As can be seen, in this example, the first terminal may accurately transmit the first configuration information to the second terminal through any one or more of the two transmission manners, so as to implement unicast connection transmission between the first terminal and the second terminal, improve accuracy of transmission, and reduce transmission delay.
In one possible example, the correspondence between the first configuration information and the first multicast service is indicated by at least one of:
the first configuration information comprises a relevant identifier of the first multicast service;
the first configuration information comprises a layer 2 address or a media access layer address associated with the first multicast service;
the first configuration information is transmitted through a layer 2 address or a media access control layer address associated with the first multicast service;
the first configuration information is transmitted over a unicast data bearer and/or a signaling bearer associated with the first multicast traffic.
The identifier related to the first multicast service is a plurality of identifiers that enable the second terminal to determine the first multicast service, for example, the identifier may be a service identifier of the first multicast service, or may be an ID identifier of the first multicast service, and the like, which is not limited herein.
For example, if the second terminal is currently performing two multicast services, namely a first multicast service and a second multicast service, the second terminal may determine the first multicast service corresponding to the first configuration information through the any one or more indication modes, and similarly, the second terminal may determine the configuration information corresponding to the second multicast service.
The first configuration information is transmitted through a layer 2 address or a media access control layer address associated with the first multicast service, or the first configuration information is transmitted through a unicast data bearer and/or a signaling bearer associated with the first multicast service, that is, in a process of transmitting the first configuration information, information associated with the first multicast service is added in a header of a corresponding protocol layer, where the information may be a layer 2 address, a media access control layer address, a unicast data bearer, a unicast signaling bearer, or the like.
As can be seen, in this example, the first terminal adds the identifier, the layer 2 address, or the media access layer address, which is related to the first multicast service, to the first configuration information, or transmits the first configuration information in a manner of a layer 2 address, a media access layer address, a unicast data bearer, and/or a signaling bearer, which are related to the first multicast service, so that the second terminal accurately obtains the first multicast service corresponding to the first configuration information when receiving the first configuration information, thereby avoiding confusion of configuration information when the second terminal performs multiple multicast services simultaneously, and improving accuracy of configuration of the multicast services.
In one possible example, the at least one second terminal comprises a plurality of second terminals; the first configuration information is transmitted over a multicast connection.
The multicast connection transmission is to implement a point-to-point network connection between the first terminal and each of the plurality of second terminals, that is, to implement a point-to-multipoint network connection transmission between the first terminal and the plurality of second terminals.
As can be seen, in this example, the first terminal transmits the first configuration information in a multicast connection transmission manner, so that the target second terminal can accurately determine the information of the first multicast service through the multicast connection without adding the associated information of the first multicast service in the first configuration information by the first terminal, which is beneficial to improving the accuracy of playing the first multicast service and reducing the data volume of the first configuration information.
In this possible example, the multicast connection transmission comprises at least one of the following transmission modes:
the first configuration information is transmitted through a layer 2 address or a media access control layer address associated with the first multicast service identifier;
the first configuration information is transmitted over a multicast data bearer and/or a signaling bearer associated with the apparatus for the first multicast service.
The first configuration information is transmitted through a layer 2 address or a media access control layer address associated with the first multicast service identifier, or the first configuration information is transmitted through a multicast data bearer and/or a signaling bearer associated with the first multicast service, that is, in a process of transmitting the first configuration information in multicast connection, information associated with the first multicast service is added in a message header of a corresponding protocol layer, where the information may be a layer 2 address, a media access control layer address, a multicast data bearer or a multicast signaling bearer, or the like.
As can be seen, in this example, the first terminal may accurately indicate the first multicast service transmitted by the multicast connection through any one or more transmission modes of the two transmission modes, so as to improve the timeliness and accuracy of determining the first multicast service when the second terminal receives the first configuration information.
In one possible example, the correspondence between the first configuration information and the target second terminal is indicated by at least one of:
the first configuration information comprises the related identification of the target second terminal;
the first configuration information comprises a layer 2 address or a medium access layer address associated with the target second terminal.
The relevant identifier of the target second terminal may be various, for example, an IP address identifier, an ID identifier, and the like, which is not limited herein.
For example, the plurality of second terminals transmitted by the first terminal through the multicast connection include a target second terminal and a second terminal a, and when both the target second terminal and the second terminal a receive the first configuration information, the target second terminal and the second terminal a may determine, through the indication information in the first configuration information, that the first configuration information is the configuration information of the target second terminal but not the configuration information of the second terminal a, and then the target second terminal may perform the configuration operation according to the first configuration information, and the second terminal a may not perform the configuration operation according to the first configuration information.
It can be seen that, in this example, when the first terminal transmits the first configuration information in the multicast connection transmission manner, the first configuration information is added with the relevant identifier of the target second terminal corresponding to the first configuration information or the associated layer 2 address or media access layer address, and the like, which is beneficial to improving the relevance of the target second terminal in accurately determining the first configuration information and the target second terminal, and improving the accuracy of configuration control.
In one possible example, the first configuration information is transmitted by a medium access layer control element, MAC CE, or a radio resource control, RRC.
The first configuration information belongs to the content of the payload part of the transmitted information, where the transmission of the content of the payload part is limited to be transmitted through a media access layer control unit MAC CE or a radio resource control RRC, and the first configuration information is transmitted through a layer 2 address or a media access control layer address associated with the first multicast service identifier, or the first configuration information belongs to the content of the limited transmission packet header part in a multicast data bearer and/or a signaling bearer transmission associated with the first multicast service, and the two are independent of each other.
In one possible example, the first configuration information is used to configure the configuration of at least one of the following layers of the second terminal:
a service data adaptation protocol SDAP layer, a packet data convergence protocol PDCP layer, a radio link control RLC layer, a media access control MAC layer and a physical PHY layer.
In one possible example, the configuration of the PHY layer includes a configuration of available resources.
As can be seen, in the present example, different available resource sets may be given for different second terminals in the first configuration information sent by the first terminal, so that resources used by different second terminals after configuration according to the configuration information are mutually independent, so as to reduce interference.
The following describes an embodiment of the present invention with reference to a specific application scenario.
Scene 1: as shown in fig. 2B, in case of unicast connection transmission, the first terminal sends the first configuration information to the target second terminal through a layer 2 address associated with the first terminal and/or the second terminal identification or through a unicast connection transmission mode of unicast data bearer and/or signaling bearer transmission between the first terminal and the second terminal, since the first configuration information is transmitted through the unicast connection, i.e., the first terminal transmits only the first configuration information to the target second terminal, the target second terminal can thus determine through the unicast connection that the first configuration information is transmitted to itself, the second terminal may or may not transmit a response message back to the first terminal upon receiving the configuration information for the target, and, the first configuration information may indicate the first multicast service associated with the first configuration information by at least one of:
the first configuration information comprises a relevant identifier of the first multicast service;
the first configuration information comprises a layer 2 address associated with the first multicast service;
the first configuration information is transmitted via a layer 2 address associated with the first multicast service;
the first configuration information is transmitted through a unicast data bearer and/or a signaling bearer associated with the first multicast service;
when the second terminal determines the mapping relation between the first multicast service and the first configuration information, the SDAP layer, the PDCP (packet data convergence protocol) (including the related configuration of security parameters), the RLC layer, the MAC layer and the PHY layer (including the configuration of available resources) are configured through the first configuration information, and then the first multicast service is carried out.
Scene 2: as shown in fig. 2C, in the case of multicast connection transmission, a first terminal transmits first configuration information to a plurality of second terminals, such as a target second terminal and a second terminal a, through layer 2 address transmission associated with a first multicast service identifier or through a multicast connection transmission mode for multicast data bearer and/or signaling bearer transmission associated with a first multicast service, so that the target second terminal and the second terminal a can accurately obtain the first multicast service corresponding to current first configuration information through the multicast transmission mode, establish a mapping relationship between the first multicast service and the first configuration information, and the first configuration information can indicate the target second terminal associated with the first configuration information through at least one of the following modes:
the first configuration information comprises a related identifier of the target second terminal;
the first configuration information comprises a layer 2 address associated with the target second terminal;
when receiving the first configuration information, the target second terminal in the target second terminal and the second terminal a obtains the above arbitrary one or more kinds of indication information by analyzing the first configuration information, determines that the first configuration information is the configuration information of the first multicast service, and further configures the SDAP layer, the PDCP layer (including the related configuration of the security parameters), the RLC layer, the MAC layer, and the PHY layer (including the configuration of the available resources) through the first configuration information, and performs the first multicast service after the configuration is completed.

the first terminal sends first configuration information aiming at a first multicast service to at least one second terminal, wherein the first configuration information is used for configuring a target second terminal in the at least one second terminal.
It can be seen that, in the embodiment of the present invention, a first terminal sends first configuration information for a first multicast service to at least one second terminal, where the first configuration information is used to configure a target second terminal in the at least one second terminal. Therefore, when the first terminal sends the multicast service, the first terminal can individually configure the target second terminal in at least one second terminal, and does not need to collectively configure the same configuration for all the second terminals, so that the configuration from a single terminal to a single terminal is realized, the flexibility and pertinence of the terminal configuration are favorably improved, and the configuration management efficiency is improved.
