Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention more apparent, the following detailed description will be given with reference to the accompanying drawings and the specific embodiments.
The design goals of the next generation mobile communication Network (Lite Network) and flexible Network (Soft, resilient Network) require Service Oriented (SO) protocol stack functions to be designed.
As shown in fig. 1, the SDAP is responsible for mapping and demapping of quality of service flows (QoS flows) and DRBs, and optional reflection mapping functions (Reflective QoS flow to DRB mapping).
As shown in fig. 2 and 3, each protocol layer performs data transmission strictly according to the upper and lower layer constraint relation of L3/L2/L1.
In 6G, with the increase of the types of information to be transmitted (6G network is a smart endogenous network, and needs to generate measurement information according to its own operation), besides service data and RRC signaling, a lot of information is required to be transferred between access layers (AS layers) of terminal side and network side, and inside the AS layers, such AS configuration or update interaction of AI model, protocol sublayer interaction, selecting appropriate protocol sublayer function according to service characteristics, etc., which all require that the protocol stack in 6G has flexibility capability of function on-demand selection, unified Protocol Data Unit (PDU) format, low redundancy overhead, no connection between protocol layers, or light connection.
In order to implement a flexible protocol stack, the following problems need to be solved:
1. consistency of peer-to-peer protocol; the protocol between the sender (terminal or network) and receiver (network or terminal) needs to be consistent.
2. Uniqueness of inter-Layer logical constraints between Lower layers (Lower layers) and Upper layers (Upper layers) between protocol layers. The flexibility of the flexible protocol stack is embodied in terms of function on-demand selection, unified Protocol Data Unit (PDU) format, low redundancy overhead, no connection or light connection between protocol layers, the requirements of functions and services between lower and upper layers being clear and unique.
3. Stability of air interface transmission; how the protocol stack functions change as needed is to better serve the transmission of user data. No matter how the function of the protocol sublayer changes according to the requirement, no influence is required to the physical layer, the wireless transmission of an air interface is not perceived, and only one data Transmission Block (TB) needs to be transmitted.
Therefore, it is necessary to reconstruct the existing RRC signaling procedure to implement service-oriented RRC signaling configuration.
The invention provides an RRC configuration scheme of SDAP function service facing to service, which takes configuration 'function service' as a Main Key (Main Key), takes QoS guarantee capability as guide, and maps a flexible mapping mode in a mode of real-time data transmission requirement, thereby realizing 'control' and 'use' decoupling, and realizing flexible function under a reduced network.
The embodiment of the invention provides a function configuration method and device, which can realize the configuration of service-oriented SDAP functions.
The embodiment of the invention provides a function configuration method, which is applied to a terminal and comprises the following steps:
reporting a capability request message of the self to network side equipment, wherein the capability request message carries a Service Data Adaptation Protocol (SDAP) service set required by the terminal;
and receiving a capability configuration message returned by the network side equipment, wherein the capability configuration message is used for configuring an SDAP service set available by the terminal in the service range of the network side equipment.
In this embodiment, through the message interaction between the terminal and the network side device, the service of the SDAP function peer to peer between the terminal and the network side device can be implemented, and the configuration of the service-oriented SDAP function can be implemented. Wherein, the capability request message and the capability configuration message are both RRC signaling.
In this embodiment, the function service of the SDAP in the signaling may be defined in the form of an array, where the array includes, but is not limited to, a set, and an enumerated type.
In this embodiment, service definition is performed in the face of the function of the SDAP, and the RRC may uniformly number the function service of the SDAP.
Wherein the SDAP function service comprises:
A. the peer functions of the sending end and the receiving end, such as remapping the service according to the IP header of the SDAP, the corresponding SDAP functions are: the receiving end and the transmitting end need to establish a set of peer-to-peer IP header (de) interleaving mechanism and (de) remapping mechanism, including PDU format, control packet transmitting and receiving rules, etc.
B. Only a function existing in a transmitting end or a receiving end, such as a complete on-demand routing function of the SDAP: the method comprises the mapping relation between PDU format and transmission channel.
C. And the following path control function: the network side is required to configure a core algorithm or rule flexibly controlled by the UE side according to the requirement.
In some embodiments, as shown in fig. 4, the set of SDAP services includes at least one of:
an SDAP service-oriented function (SO Function set of SDAP) configured in the form of an array, wherein the array includes, but is not limited to, a set, an enumerated type;
basic function of SDAP (Basic Function of SDAP). This part of the functionality may be the default SDAP functionality in RRC signaling. Related functions are default functions of the SDAP, including but not limited to: the processing mode of the data is a default mode, the QoS guarantee level used for connection with a lower layer is a default value, the transmission mode of the data packet is a default mode, and the like.
The quality of service QoS guarantee level of the protocol data unit PDU when the SDAP transmits data with a lower layer is configured in the form of an array, wherein the array includes, but is not limited to, a set, an enumerated type, and the lower layer includes a medium access control MAC layer, a packet data convergence protocol PDCP layer, and/or a radio link control RLC layer. This content in RRC signaling identifies QoS guarantee requirements for data transmission by all lower layers (e.g., MAC layer, PDCP/RLC layer) adjacent to the SDAP. And according to the characteristics of downlink or uplink data (comprehensively formulated according to the QoS requirements of the service required to be supported by the SDAP and combining the characteristics of SDAP data packet processing) which are required to be transmitted by the SDAP, formulating a QoS guarantee level suitable for the SDAP. When SDAP and lower layer thereof perform data transmission, a proper transmission carrier is selected for data transmission according to the configured QoS guarantee and the capability of the SDAP layer and lower layer transmission carriers (such as TNL: transport Network Layer transmission network layer).
In this embodiment, the QoS guarantee level for transmitting the SDAP PDU is defined in the face of the packet type that the SDAP may transmit. By configuring the QoS guarantee level of the SDAP PDU, the terminal and the base station can maintain the consistent QoS guarantee level. And the terminal and the base station realize the configured QoS guarantee requirements according to the direct transmission capacity of the SDAP-MAC in each terminal and the base station. Namely, the soft requirement of QoS class is configured, and hard connection like DRB is not configured, which means that the information carried between SDAP-MAC is not needed to be carried when in air interface transmission, thereby reducing RRC signaling overhead.
As shown in fig. 5, after the terminal accesses the network, a capability request message is sent to a network side device, such as a base station, where the capability request message carries its required SDAP function service set SO-SDAP-Config (initiated on demand, including QoS guarantee level). In this way, the characteristics of the terminal processing the data at the SDAP layer can be determined. For example, if the terminal is a single terminal (such as a water meter) with the function of the internet of things, the terminal only needs to support the basic function of the SDAP and the targeted QoS guarantee level.
In this process, the terminal builds RRC signaling according to the format of fig. 4, assigns a value to the corresponding field, and records the SDAP service set and QoS guarantee level that the terminal itself can use or request. In this embodiment, the function service of the SDAP in the RRC signaling is defined in the form of an array; the Main Key (Main Key) configured in the RRC signaling is not a 5G DRB any more, but is a direct SDAP function service (SO-SDAP-Config), and the terminal and the base station side peer-to-peer SDAP function service is realized through handshake between the terminal and the base station; in addition, the QoS guarantee level of data transmission between SDAP-MAC is defined in an array mode, and the QoS guarantee level between the SDAP-MAC at the peer of the terminal and the base station side is realized through handshake between the terminal and the base station; according to the technical scheme of the embodiment, the protocol functions can be flexibly selected according to requirements; and realizing 0 switching.
In this embodiment, the terminal may use the existing RRC signaling procedure to handshake immediately after accessing the network side device; the new service application may be initiated at any time in the data transmission process using the default configuration, and the RRC procedure used at this time may be an RRC signaling procedure newly added as shown in fig. 2, or an existing RRC signaling procedure may be used.
The embodiment of the invention also provides a function configuration method which is applied to the network side equipment and comprises the following steps:
receiving a capability request message reported by a terminal, wherein the capability request message carries a Service Data Adaptation Protocol (SDAP) service set required by the terminal;
determining an SDAP service set available to the terminal according to the SDAP service capability set available to the terminal;
and sending a capability configuration message to the terminal, wherein the capability configuration message is used for configuring an SDAP service set available for the terminal in the service range of the network side equipment.
In this embodiment, after receiving the capability request message, the network side device combines with the SDAP service capability set SO-SDAP-Config that can be provided by the network side device itself, selects the service same as the set requested by the terminal to provide the terminal with the SDAP service available to the network side device (or the wireless cell), and then configures the service to the terminal through RRC signaling.
In this embodiment, through the message interaction between the terminal and the network side device, the service of the SDAP function peer to peer between the terminal and the network side device can be implemented, and the configuration of the service-oriented SDAP function can be implemented. Wherein, the capability request message and the capability configuration message are both RRC signaling.
In this embodiment, the function service of the SDAP in the signaling may be defined in the form of an array, where the array includes, but is not limited to, a set, and an enumerated type.
In this embodiment, service definition is performed in the face of the function of the SDAP, and the RRC may uniformly number the function service of the SDAP.
Wherein the SDAP function service comprises:
A. the peer functions of the sending end and the receiving end, such as remapping the service according to the IP header of the SDAP, the corresponding SDAP functions are: the receiving end and the transmitting end need to establish a set of peer-to-peer IP header (de) interleaving mechanism and (de) remapping mechanism, including PDU format, control packet transmitting and receiving rules, etc.
B. Only a function existing in a transmitting end or a receiving end, such as a complete on-demand routing function of the SDAP: the method comprises the mapping relation between PDU format and transmission channel.
C. And the following path control function: the network side is required to configure a core algorithm or rule flexibly controlled by the UE side according to the requirement.
In some embodiments, as shown in fig. 4, the set of SDAP services includes at least one of:
an SDAP service-oriented function (SO Function set of SDAP) configured in the form of an array, wherein the array includes, but is not limited to, a set, an enumerated type;

Related functions are default functions of the SDAP, including but not limited to: the processing mode of the data is a default mode, the QoS guarantee level used for connection with a lower layer is a default value, the transmission mode of the data packet is a default mode, and the like.
The quality of service QoS guarantee level of the protocol data unit PDU when the SDAP transmits data with a lower layer is configured in the form of an array, wherein the array includes, but is not limited to, a set, an enumerated type, and the lower layer includes a medium access control MAC layer, a packet data convergence protocol PDCP layer, and/or a radio link control RLC layer. This content in RRC signaling identifies QoS guarantee requirements for data transmission by all lower layers (e.g., MAC layer, PDCP/RLC layer) adjacent to the SDAP. And according to the characteristics of downlink or uplink data (comprehensively formulated according to the QoS requirements of the service required to be supported by the SDAP and combining the characteristics of SDAP data packet processing) which are required to be transmitted by the SDAP, formulating a QoS guarantee level suitable for the SDAP. When SDAP and lower layer thereof perform data transmission, a proper transmission carrier is selected for data transmission according to the configured QoS guarantee and the capability of the SDAP layer and lower layer transmission carriers (such as TNL: transport Network Layer transmission network layer).
In this embodiment, the QoS guarantee level for transmitting the SDAP PDU is defined in the face of the packet type that the SDAP may transmit. By configuring the QoS guarantee level of the SDAP PDU, the terminal and the base station can maintain the consistent QoS guarantee level. And the terminal and the base station realize the configured QoS guarantee requirements according to the direct transmission capacity of the SDAP-MAC in each terminal and the base station. Namely, the soft requirement of QoS class is configured, and hard connection like DRB is not configured, which means that the information carried between SDAP-MAC is not needed to be carried when in air interface transmission, thereby reducing RRC signaling overhead.
As shown in fig. 5, after the terminal accesses the network, a capability request message is sent to a network side device, such as a base station, where the capability request message carries its required SDAP function service set SO-SDAP-Config (initiated on demand, including QoS guarantee level). In this way, the characteristics of the terminal processing the data at the SDAP layer can be determined. For example, if the terminal is a single terminal (such as a water meter) with the function of the internet of things, the terminal only needs to support the basic function of the SDAP and the targeted QoS guarantee level.
In this process, the terminal builds RRC signaling according to the format of fig. 4, assigns a value to the corresponding field, and records the SDAP service set and QoS guarantee level that the terminal itself can use or request. In this embodiment, the function service of the SDAP in the RRC signaling is defined in the form of an array; the Main Key (Main Key) configured in the RRC signaling is not a 5G DRB any more, but is a direct SDAP function service (SO-SDAP-Config), and the terminal and the base station side peer-to-peer SDAP function service is realized through handshake between the terminal and the base station; in addition, the QoS guarantee level of data transmission between SDAP-MAC is defined in an array mode, and the QoS guarantee level between the SDAP-MAC at the peer of the terminal and the base station side is realized through handshake between the terminal and the base station; according to the technical scheme of the embodiment, the protocol functions can be flexibly selected according to requirements; and realizing 0 switching.
