The service management method and node provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in FIG. 2, an embodiment of the present application provides a service management method 200, the method can be executed by a first node, in other words, the method can be executed by software or hardware installed on the first node, the method includes Follow the steps below.

S202: The first node sends quality of service (Quality of Service, QoS) configuration information, where the QoS configuration information is used to manage the second node by domain, and each domain includes at least one second node.

The service management methods provided by the various embodiments of this application may be applied to a wireless short-range communication system (ShortRange Communication Technology). In the wireless short-range communication system, the first node may be a management node, and the management node may also be referred to as a C node (Control Node); the second node may be a managed node, and the managed node may also be referred to as a T node (Terminal Node) or a terminal node.

It can be understood that the service management methods provided by the various embodiments of the present application can not only be applied in the vehicle-mounted wireless short-range communication system, but also can be used in other short-range communication scenarios, such as a home Internet of Things system. The first node) performs business management on smart furniture such as refrigerators and washing machines (equivalent to the second node).

For the domains mentioned in the various embodiments of this application, for example, in the vehicle wireless short-range communication system, it may include the advanced driver assistance system domain, the body control domain, the powertrain domain, the chassis control domain, and the entertainment domain. In the home Internet of Things system, it can include a domain composed of lighting systems, an entertainment domain composed of TV speakers, etc., a domain composed of refrigerators and washing machines, and so on.

Each of the above domains may include at least one second node. For example, the entertainment domain in the above-mentioned vehicle-mounted wireless short-range communication system may include second nodes such as displays, terminals, mobile phones, etc.; The assembly domain may include second nodes such as the engine, gearbox, clutch, etc.

The QoS configuration information mentioned in this embodiment is used to manage the second node by domain. For example, different domains correspond to different service types, and multiple second nodes in the same domain may correspond to the same service type. In this way, The first node may configure a set of QoS configuration information for each domain, and the QoS configuration information corresponding to different domains may be different.

Optionally, the QoS configuration information mentioned in the various embodiments of this application is used to configure at least one of the following for the second node:

1) A service transmission mode, which includes, for example, Acknowledged Mode (AM), Unacknowledged Mode (UM) or Transparent Mode (TM).

2) Mapping of service transmission channels, such as mapping of service data and logical channels.

3) Transmission channel priority.

4) Hybrid Automatic Repeat Request (HARQ) feedback mode.

5) Preconfigure uplink configuration, such as uplink transmission resource configuration.

6) Access request configuration information.

7) Data encoding method.

8) Whether the business is encrypted.

9) A timer for ensuring service progress, which can be used in conjunction with time delay requirements.

10) Service discontinuous reception (Discontinuous Reception, DRX) configuration.

In an example, before S202, the following steps may be further included: the first node receives service request information from the second node, where the service request information includes the service type of the second node; wherein the QoS configuration information is the first node A node is configured for the second node according to the service type.

In this example, different second nodes (such as T nodes) request service resources from the first node (such as C node) by initiating service requests, so that the first node can be the second node according to the service type of the second node. Allocate channel resources and other physical layer configuration information that affects service quality requirements (ie, the aforementioned QoS configuration information), and then the control module of the second node performs resource configuration and channel priority management on the physical layer.

In another example, the QoS configuration information mentioned in S202 is configured by the first node for the second node during the access process of the second node, and the QoS configuration information is used to The signaling of the second node is configured.

This example can be used for QoS configuration of signaling. During the access process of the second node (such as the T node), the first node (such as the C node) can assign a QoS configuration to the second node that has passed the authentication, and perform signaling interaction management according to the QoS level, and allocate signaling resources, etc. .

The example may include the following steps: the second node initiates a random access procedure to the first node; the first node sends an identification request to the second node; the second node sends an identification response to the first node; the identity of the second node In the case of passing the authentication, the first node sends the QoS configuration information to the second node; in this way, the second node can perform relevant configuration according to the QoS configuration information, and subsequently the second node and the first node perform signaling exchange management according to the QoS level , allocate signaling resources, etc.

In another example, the QoS configuration information mentioned in S202 is sent by the first node in a broadcast manner, and the QoS configuration information is pre-configured.

In this example, a pre-configured QoS configuration list (ie, QoS configuration information) of a specific service in the second node and the first node can be established, stored in the non-volatile memory of the first node, and the first node can send it by broadcasting to the second node.

When the second node satisfies the service type of the specific service in the QoS configuration list, it can directly use the preconfigured QoS configuration list to perform logical channel mapping and data transmission without performing the step of requesting QoS configuration in the first example.

For example, in the vehicle wireless short-range communication system, the vehicle key system uses a radio bearer (Radio Bearer, RB) X, and the radio bearer X here can be a fixed radio bearer identification (ID), and the radio bearer X on this bearer The service uniformly uses the QoS configuration X, where X in this example represents the number of the radio bearer and the QoS configuration.

In the service management method provided by the embodiment of the present application, the first node sends QoS configuration information, and wirelessly manages the second node in the vehicle by domain, which can meet the needs of vehicle wireless short-range communication; at the same time, each domain includes at least One second node, in this way, the first node can perform unified management on at least one second node in the domain, thereby improving communication efficiency.

The improvement of communication efficiency mentioned above is relative to the separate management of each second node. For example, the first node can perform unified management of multiple second nodes in a certain domain. The manner in which multiple second nodes in the domain are separately managed can improve communication efficiency.

Optionally, before the first node sends the QoS configuration information in Embodiment 200, the following steps may be further included: the first node establishes an association relationship between at least two of the following: domain state control information (may be referred to as A); wireless communication control Status information (may be abbreviated as B); QoS identification (ID).

It can be understood that in the case where the first node establishes the association relationship between the above at least the two, the QoS configuration information sent by the first node may also include the association relationship.

The domain state control information A mentioned above may include at least one of the following domains: the security level of the domain; the function implemented by the domain; the business requirements of the domain; the unique identification ID of the domain; the domain name; the connection status of the domain; The channel priority of the domain; the access level of the domain.

The above service requirements include at least one of the following: service type (such as video, audio, broadcast, vehicle control information, etc.); service level (such as large traffic, low latency, etc. service requirements); service transmission rate; service coding format; service feedback way etc.

The connection state of the above-mentioned domain includes a connected state and an idle state; wherein, in the first case, the connection state of the domain is the connected state; in the second case, the connection state of the domain is the idle state; The first situation includes: at least one of the second nodes in the domain is in a connected state, and the second situation is a situation other than the first situation, for example, the second situation includes All second nodes are in an idle state. In this example, if at least one second node in a certain domain accesses the network, the domain is in a connected state; otherwise, the domain is in an idle state.

The wireless communication control state information B mentioned above may include control plane management information of the wireless device, and may specifically include at least one of the following: logical channel mapping relationship; logical channel priority; data feedback mode; random access preamble; the Access state of the second node; data compression mode; whether data is encrypted or decrypted; data encryption and decryption algorithm; data segment number; wireless security policy; system key.

In one example, the first node may establish an association relationship between the domain state control information A and the wireless communication control state information B. This operation may be established when the second node initiates a service request, or may be directly allocated by the first node. The first node may also establish a unique QoS identifier, such as a QoS ID, for each QoS type, and establish an association relationship between the domain state control information A and the service type QoS ID.

In this example, the first node can be divided according to the domain. When the domain is in the connected state, QoS configuration information can be allocated to the second node in the domain. The same QoS configuration information can be associated with the node IDs of one or several second nodes at the same time. A plurality of second nodes can use the same logical channel to implement different logical channel multiplexing and priority management of domains with different QoS.

Through the above steps, the association relationship among the domain state control information A, the wireless communication control state information B, and the QoS ID can be realized.

It can be understood that the establishment of the association relationship between the above three should not be restricted by the order, that is, it is also possible to establish the association relationship between the wireless communication control state information B and the QoS ID first, and then establish the association relationship between the domain state control information A and the QoS ID. , should support all cases of permutations and combinations of the three.

In this embodiment, the association relationship between the QoS ID and the logical channel (included in the wireless communication control state information B) can be further implemented, thereby realizing the management of the wireless communication control state information B by the domain state control information A.

The above-mentioned association relationship is shown in FIG. 3 , which is a schematic diagram of the association relationship between the QoS identifier, the second node in the domain, and the logical channel according to an embodiment of the present application. In the example shown in FIG. 3 , QoS- 1 is associated with logical channel 1, QoS-2 is associated with logical channel 2, and QoS-3 is associated with logical channel 3. In this example, the second nodes included in the domain associated with QoS-1 and logical channel 1 are node 1, node 2, and node 3; the second nodes included in the domain associated with QoS-2 and logical channel 2 are node 4, node 2, and node 3. Node 5 and Node 6; The second node included in the domain associated with QoS-3 and Logical Channel 3 is Node 7. It can be understood that the same second node can also be located in two domains, for example, the second node is a mobile phone, the mobile phone is located in the first domain when transmitting service type 1, and the mobile phone is located in the second domain when transmitting service type 2, etc. Wait.

Optionally, before the first node sends the QoS configuration information in Embodiment 200, the following step may be further included: the first node establishes an association relationship between the QoS identifier and the layer 2 specific function. It can be understood that the association relationship between the QoS identifier and the layer 2 specific function may also be included in the QoS configuration information sent by the first node, and the second node can implement the layer 2 specific function according to the QoS configuration information. Layer 2 may be a Media Access Control (Media Access Control, MAC) layer.

The above-mentioned first node establishes the association relationship between the QoS identifier and the layer 2 specific function, including at least one of the following:

1) Establish the association relationship between the QoS identifier (such as QoS-1) and the random access of the layer 2 function;

2) Establish an association relationship between QoS identifiers (such as QoS-2) and high-efficiency and low-noise transmission of Layer 2 functions;

3) Establish the relationship between the QoS identifier (such as QoS-3) and the low latency of the layer 2 function;

4) Establish the association relationship between the QoS identifier (such as QoS-4) and the layer 2 function signaling transmission;

5) Establish an association relationship between a QoS identifier (eg, QoS-5) and a layer 2 specific service, for example, establish an association relationship between QoS-5 and a layer 2 specific service, and use a preconfigured QoS configuration for this service.

The above-mentioned establishing the association relationship between the QoS identifier and the layer 2 specific function includes: performing layer 2 mapping by associating the QoS identifier and the MAC header to establish the association relationship between the QoS identifier and the layer 2 specific function.

Specifically, for the connection between the above-mentioned QoS identifier and the Layer 2 function, the Layer 2 mapping can be performed by associating the QoS ID and the MAC header, so as to identify which QoS has activated which Layer 2 function.

Optionally, the QoS configuration information mentioned in the foregoing embodiments is used to manage the second node by domain, including at least one of the following:

1) the QoS configuration information is used to manage the access priority of the second node by domain;

2) The QoS configuration information is used to manage the signaling transmission of the second node by domain;

3) The QoS configuration information is used to manage the channel priority of the second node by domain;

4) The QoS configuration information is used to manage the data transmission of the second node by domain.

In one example, the first node maintains an association relationship between the second node and the QoS service of the second node. In this example, the first node performs addressing and sending of the QoS service through a flow ID (Flow ID); wherein, the QoS service is identified through the flow ID.

In this example, the first node (eg, node C) is capable of maintaining multiple lists of different second nodes (eg, node T) corresponding to QoS services. In this example, the concept of Flow ID is added, which is essentially a combination of the QoS ID and the node ID of the second node, and is used to uniquely identify data or signaling services. The Flow ID can be mapped with the DRB or with the logical channel to uniquely identify the destination address of the transport block (TB) data on a certain channel. In this way, the first node can address services and send data through the Flow ID.

Optionally, the embodiment 200 may further include the following step: data transmission is performed between the first node and the second node in the form of adding data with a stream identifier; wherein the data is not added with an inter-layer header and parsing.

In this example, for the service managed according to QoS, it may be different according to the requirements. For example, for the active noise reduction service, the optional Packet Data Convergence Protocol (PDCP) encryption is not required, PDCP is not performed, and the wireless link layer The control (Radio Link Control, RLC) packet header is added and parsed, and data is directly transmitted in the form of Flow ID + data (DATA).

In one example, the first node preconfigures QoS and uplink resources to the second node. The second node directly sends the data to the first node in the form of FLOW ID+data without any signaling.

Optionally, the data transmitted in this instance may or may not be encrypted

Optionally, in this instance, data parsing can be performed directly between the first node and the second node, without adding and parsing inter-layer headers. This transmission mode can be selected according to the difference of QoS and controlled by the first node.

In order to describe in detail the service management method provided by the embodiments of the present application, the following will be described with reference to two specific embodiments.
