Description

Communication method, device and electronic equipment

Technical Field

The present application relates to the field of communication technology, and in particular to a communication method, device and electronic equipment.

Background Art

At present, one of the ways to improve the reliability of Ultra-Reliable and Low Latency Communications (URLLC) technology is to establish an end-to-end (E2E) redundant session. The user equipment (UE) mainly initiates a session establishment request for two protocol data unit (PDU) sessions based on two different routing selection strategies/local configurations. The session management function (SMF) determines whether the UE allows the establishment of two redundant PDU sessions. The SMF triggers the establishment of two E2E isolated sessions, selects two PDU session anchors, connects to the same data network (DN), determines the pair identifier (ID) and redundant sequence number (RSN), and returns them to the UE and the radio access network (RAN) equipment.

That is, in the existing standard protocol, the fifth-generation mobile communication (5th-Generation, 5G) system supports the establishment of two redundant PDU sessions to ensure E2E deterministic capabilities, that is, one UE initiates a request to establish two redundant PDU sessions, and the 5G core network (such as SMF, Policy Control Function (PCF)) perceives and establishes two redundant PDU sessions. However, it cannot support some native communication functions, such as frame replication and frame elimination (Frame Replication and Elimination for Reliability), dual-transmission and selective reception, etc., which can easily lead to poor service performance.

The process of the above method is described in detail below with some specific embodiments. Taking the first communication function of dual transmission and selective reception as an example, dual transmission and selective reception can be understood as establishing two concurrent (independent) links, by copying the data packets to be sent at the sending end and sending them through two independent links, and the receiving end can choose to receive only one of the transmitted data packets.

Currently, one of the ways to improve reliability with Ultra-Reliable and Low Latency Communications (URLLC) technology is to establish end-to-end (E2E) redundant sessions. The core idea of this technology is:

1. The UE initiates session establishment requests for two PDU sessions (with different data network names (DNN), Internet Protocol descriptors (IP descriptors)/MAC addresses + VLAN IDs) based on two different UE Route Selection Policy (URSP) rules/local configurations;

2. SMF determines whether the UE is allowed to establish two redundant PDU sessions. SMF can make decisions based on UE requests, contract information, Policy Control Function (PCF) instructions, local policies, etc.

3. SMF triggers the establishment of two E2E isolated sessions, selects two PSAUPF anchor points, connects to the same DN; determines the pairID and RSN, and returns to the UE and RAN equipment.

According to the definition method of relevant protocol standards, the 5G system supports the establishment of two redundant PDU sessions to ensure E2E deterministic capabilities. That is, one UE initiates a request to establish two redundant PDU sessions, and the 5G core network (such as SMF, PCF) perceives and establishes two redundant PDU sessions. According to the definition methods of relevant protocol standards, there are two main technical problems with 5G network capabilities: 1) It is unable to support native dual-transmission selective reception functions. On the user side, UE and UPF can only identify service flows, and cannot automatically trigger the opening or closing of the dual-transmission selective reception function based on service flow identification; on the control side, the 5G core network cannot create redundant sessions that support dual-transmission selective reception based on UE identification, application and other information, and lacks network-industry collaboration; 2) It is unable to support dual-transmission selective reception session management based on multiple UEs/paths. For example, especially for the dual-transmission selective reception scenario of single device and multiple UEs, how to select UE and how many UEs to select for the dual-transmission selective reception session of the device needs to be solved. In addition, how to superimpose the dual-transmission selective reception function based on UE-UE and time-sensitive network (TSN) sessions commonly used in industrial applications has not yet been solved, and there is room for improvement in network resources and service performance.

Therefore, the embodiment of the present application proposes a solution for flexibly selecting dual-transmit and selective-receive paths. On the basis of the 5G network's native support for dual-transmit and selective-receive capabilities, it implements multi-UE/path selection and management for dual-transmit and selective-receive functions, thereby improving the network's inherent determinism, improving network resource utilization efficiency, and improving communication service performance. The main solutions involved include: a multi-path selection solution based on the dual-transmit and selective-receive function; a multi-path selection solution for special UE-UE communication scenarios.

(I) Solution 1: Multi-path selection solution

The core idea of this solution is that during the process of establishing or modifying a session, SMF dynamically selects a dual-transmit and selective-receive link from candidate dual-transmit and selective-receive terminals/paths based on factors such as link quality and connection requirements, thereby achieving deterministic and highly reliable communication assurance through redundant sessions. The process is shown in Figure 8.

First, during the session establishment process, SMF may determine whether to enable the dual-transmit selective reception function for the UE's downstream device based on UE request, session subscription information, dynamic PCC rule, local configuration and other information, and decide on the dual-transmit selective reception session path. According to the session establishment process, the following steps are specifically included:

UE sends a session establishment request to SMF (via AMF). The session request message may newly define one or more of the following information:

Double send and receive session ID;

UE dual-transmit selective reception capability (including: whether the UE supports dual-transmit selective reception, and the protocols that support dual-transmit selective reception, such as FRER, HSR, RTP, QUIC, DetNet and other protocols);

Device identification (such as device ID), device address (such as device MAC address).

SMF obtains the subscription information related to the UE session from UDM/UDR. The session subscription information newly defines the information related to the dual-send and selective-receive session, including one or more of the following information:

Device identification (such as device ID), device address (such as device MAC address);

Information about UEs connected to the device (in the form of UE group and UE list; in the form of UE identifiers, such as UE ID, SUPI, GPSI, etc.);

UE priority (referring to the priority of selecting UE connected to the device for dual transmission and reception);

Maximum number of UEs/sessions allowed for dual-transmit selective reception;

Indication of the dual-transmit selective reception function on/off (e.g., on/off), dual-transmit selective reception supported protocols (e.g., FRER/HSR/RTP/DetNet, etc.), dual-transmit selective reception allowed service range (e.g., cell ID, TA(s), TA list, AoI, etc.), dual-transmit selective reception allowed service time (e.g., on/off time, etc.), etc.;

Dual-send and selective-receive QoS requirements.

The PCF issues dynamic PCC rules, or the SMF obtains one or more of the following new definition information based on local configuration:

Device identification (such as device ID), device address (such as device MAC address);

Information about UEs connected to the device (in the form of UE group and UE list; in the form of UE identifiers, such as UE ID, SUPI, GPSI, etc.);

UE priority (referring to the priority of selecting UE connected to the device for dual transmission and reception);

Maximum number of UEs/sessions allowed for dual-transmission and selective reception;

Indication of the dual-transmit selective reception function on/off (e.g., on/off), dual-transmit selective reception supported protocols (e.g., FRER/HSR/RTP/DetNet, etc.), dual-transmit selective reception allowed service range (e.g., cell ID, TA(s), TA list, AoI, etc.), dual-transmit selective reception allowed service time (e.g., on/off time, etc.);

Dual-send and selective-receive QoS requirements.

Based on the dual-transmit selective reception related information obtained from the above steps, SMF decides the dual-transmit selective reception support UE/session of the downstream device/industrial terminal.

Based on the above decision, SMF decides whether to enable the dual-transmit selective reception function and corresponding configuration of the UE session, and sends a session establishment response/modification request. Specific new definition of the sent information:

Indication of the dual-transmit selective receiving function on and off (e.g., on/off);

Dual-transmit and selective-receive support protocols (such as FRER/HSR/RTP/DetNet, etc.)

Secondly, newly defined capability opening and several subscription processes for AMF and UPF enable SMF to dynamically select the dual-transmit and selective-receive path based on factors such as location, time, and QoS quality, and flexibly enable and configure the dual-transmit and selective-receive function through the session modification process. Specific steps may include:

The AF initiates a capability opening request/subscription to the PCF via the NEF, which may affect the update of the dynamic PCC rule (i.e. the dynamic PCC rule mentioned above). The newly defined information includes one or more of the following:

Device identification (such as device ID), device address (such as device MAC address);

Information about UEs connected to the device (in the form of UE group and UE list; in the form of UE identifiers, such as UE ID, SUPI, GPSI, etc.);

UE priority (referring to the priority of selecting UE connected to the device for dual transmission and reception);

Maximum number of UEs/sessions allowed for dual-transmission and selective reception;

Indication of the dual-transmit selective reception function on/off (e.g., on/off), dual-transmit selective reception supported protocols (e.g., FRER/HSR/RTP/DetNet, etc.), dual-transmit selective reception allowed service range (e.g., cell ID, TA(s), TA list, AoI, etc.), dual-transmit selective reception allowed service time (e.g., on/off time, etc.);

Dual-send and selective-receive QoS requirements.

SMF initiates N4 subscription request to UPF. The newly defined subscription information includes:

Device or DN address;

QoS quality information (e.g., UL/DL/RTT latency, PDV, data rate, congestion information, packet loss rate, etc.)

SMF initiates a subscription request for UE location to AMF:

UE location granularity, such as cell ID, TA(s), TA list, AoI, RAN node, etc.

As shown in FIG. 9 , Example 1: Session establishment process:

1. The UE initiates a session establishment request to the AMF. The NAS message newly carries the following information: dual-send selective reception session ID, device MAC address, device ID, UE dual-send selective reception capability, etc.

2. AMF selects SMF;

3. AMF sends a session establishment request to SMF, and the request carries the same message as 1;

4. SMF obtains contract information (contract data) based on Nudm_SDM_Get. Among them, the newly added contract information includes: UE priority of the dual-transmitter and receiver device connection, the maximum allowed UE/session number, etc.;

5. SMF sends a PDU session establishment response to AMF;

6. PDU session authentication/authorization;

7. PCF selection, SM strategy collaborative establishment/SM initiated strategy collaborative modification;

8. UPF selection;

9. SM initiates collaborative modification of strategies;

10. SMF initiates N4 session establishment/modification request to UPF, adding new request information: current UE connection device or DN address, QoS quality information reported based on QoS monitoring, etc.;

12. AMF sends dual-send selective reception start indication and capability configuration via NAS message;

13. AN resource establishment;

14. The RAN device sends a PDU session response to the AMF.

15. AMF sends a PDU session update request to SMF;

16. SMF sends an N4 session modification request to UPF, and UPF sends an N4 session modification response to SMF, registering with UDM through SMF;

17. SMF sends a PDU session update response to AMF;

18. AMF sends a PDU session update notification to SMF;

19. SMF sends IPv6 address configuration to UE;

20. SM initiates collaborative modification of strategies;

21. Cancel subscription.

Example 2: As shown in FIG10 , the capability opening process:

1. AF initiates dual-transmission selective reception activation/subscription request. The activation information mainly configures the dual-transmission selective reception capability, including dual-transmission selective reception switch indication, dual-transmission selective reception UE priority of the device connection, the maximum allowed number of sessions/UEs and allowed areas, etc. The subscription information mainly obtains the dual-transmission selective reception capability, including dual-transmission selective reception switch status, UE location, etc.

2. Whether NDF authorization allows AF to activate/subscribe to the dual-send and selective-receive capability;

3. NEF sends a policy control authorization establishment request to PCF. The activation or subscription message is the same as 1.

4. PCF determines whether to allow policy control authorization to be established and responds;

5. NEF responds to AF whether to allow the activation/subscription request;

6. NEF subscribes to the PCF for information related to dual-transmission selective reception, including dual-transmission selective reception switch status, UE location, etc.

7. PCF initiates a policy control update request to SMF. It may activate the dual-transmission selective reception capability, including dual-transmission selective reception switch indication, dual-transmission selective reception UE priority of device connection, maximum allowed number of sessions/UEs and allowed area, etc. It may also subscribe to dual-transmission selective reception related information, including dual-transmission selective reception switch status, UE location, etc.

8. Based on the subscription information in 7, SMF initiates UE location subscription to AMF;

9. Based on the activation information in 7, SMF dynamically selects the dual-transmit selective reception session/UE, and initiates the session modification process accordingly, and sends the dual-transmit selective reception activation indication and configuration to the corresponding UE and UPF;

10. SMF initiates a policy control response to PCF, including the dual-transmit selective receiving switch status, UE location, etc.;

11. PCF sends an activation/subscription response to NEF, including the dual-transmit selective receiving switch status, UE location, etc.;

12. NEF sends policy control authorization activation/subscription notification information including 3 and/or 6 to AF.

(II) Solution 2: Multi-path selection solution based on UE-UE communication

The core idea of this solution is that, regardless of the scenario where a single UE supports dual-transmission selective reception or the scenario where multiple UEs support dual-transmission, adding or reducing a UE/path in either UL or DL direction requires triggering the new UE and UPF to turn on or off the dual-transmission selective reception function.

For the scenario where multiple UEs support dual-send and selective-receive sessions (as shown in Figure 11):

1. UE1 and UE2 are connected to different downstream devices 1 and 2 respectively to perform terminal intercommunication;

2. UE3 connected to the same device 1 as UE1 initiates a session establishment process;

3. Based on the dual-transmission selective reception related information of the three PDU sessions (which can be obtained through one or more steps 1, 2, 3, 6, 7, and 8 of Solution 1), SMF decides whether and how to enable the dual-transmission selective reception function for PDU session 1 and PDU session 3 corresponding to UE1 and UE3;

4. Based on 3, SMF initiates a session modification request to UE1 and a session establishment response/modification request to UE3 based on PDU1 and PDU3 respectively. The two sessions send the same dual-transmission and selective reception related configuration, which may specifically include:

Indication of the dual-transmit selective receiving function on and off (e.g., on/off);

Dual-transmit and selective-receive support protocols (such as FRER/HSR/RTP/DetNet, etc.).

For the scenario where a single UE supports dual-send and selective-receive sessions (as shown in Figure 12):

1. UE1 and UE2 are connected to different downstream devices 1 and 2 respectively to perform terminal intercommunication;

2. UE1 initiates a new session establishment process for PUD3;

3. Based on the dual-transmission selective reception related information of the three PDU sessions (which can be obtained through one or more steps 1, 2, 3, 6, 7, and 8 of Solution 1), SMF decides whether and how to enable the dual-transmission selective reception function for the two PDU sessions 1 and PDU session 3 of UE1;

4. Based on 3, SMF initiates a session modification request to PDU session 1, and/or initiates a session establishment response/modification request to PDU session 3. The two sessions send the same dual-transmission and selective reception related configuration to UE1, which may specifically include:

Indication of the dual-transmit selective receiving function on and off (e.g., on/off);

Dual-transmit and selective-receive support protocols (such as FRER/HSR/RTP/DetNet, etc.).

The method proposed in the embodiment of the present application can realize multi-UE/path selection and management for dual-transmission and selective reception functions on the basis of the native support of dual-transmission and selective reception capabilities of the 5G network, thereby improving the inherent determinism of the network and the efficiency of network resource utilization. It can be widely used in vertical industries including but not limited to 5G+Industrial Internet, smart power, etc.
