Description
Technical Field
The present invention relates to the field of communications, and in particular, to a node selection method, an apparatus, and a node.
Background

Especially in the development of 3GPP 5G, the end-to-end delay of 5G services or applications is required to be within several milliseconds, and the air interface is required to be from several hundred microseconds to 1.5 milliseconds. According to the current system test, when the end-to-end time delay of transmitting 32byte data is about 16ms, the air interface time delay is 4-5 milliseconds; furthermore, the reliability requirement is that the reliability of an air interface within the set delay requirement reaches 99.9% -99.999%, so that the current system cannot meet the requirements of the future 5G service or application on delay and reliability.
In summary, how to reduce the time delay in the transmission process and achieve the corresponding high reliability is an urgent problem to be solved at present. In order to meet the transmission requirements of low time delay and high reliability, the physical layer is greatly changed, such as the change of TTI (for example, a shorter TTI is adopted or different TTIs are adopted in a self-adaptive manner), the change of a frame structure (the symbol overhead occupied by some information is changed), and the like; while the protocol stack for the user plane also needs to be simplified. But for other services that do not have special requirements on latency, other approaches will be taken in the physical layer and user plane protocol stack. Therefore, when transmitting a service with a low-latency high-reliability requirement, a mechanism of a physical layer or a user plane needs to be known, and a protocol stack of the physical layer or the user plane supporting the low-latency high-reliability capability needs to be adopted to meet the requirement, but a method for selecting a node with the capability of transmitting the low-latency high-reliability transmission does not exist at present.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
As shown in fig. 1, an embodiment of the present invention provides a node selection method, which specifically includes:
step 101: the method comprises the steps of obtaining a service request initiated by a user terminal and transmission capability indication information of a second node in the same access network with a first node.
Wherein, the first node is a control plane node, the second node is a user plane node or a transmission node, and a specific network architecture diagram can be shown in fig. 2 or fig. 3; in fig. 2, the control plane and the user plane are integrated, that is, a control plane node and a user plane node are deployed on the same physical node, control information and user data between two types of nodes and a core network are transmitted through the same channel, and control signaling and user data of the two types of nodes and a transmission node are transmitted through the same channel. The transmission nodes can be connected with the control plane nodes and the user plane nodes independently, or a plurality of transmission nodes form a pool or a cluster and are connected with the control plane nodes and the user plane nodes; and the functionality of the user plane node may also be moved down to the transport node in whole or in part. In fig. 3, a control plane is separated from a user plane, a control plane node and a user plane node are deployed on different physical nodes, control signaling and user data between two types of nodes and a core network are transmitted through different channels, and control signaling and user data between the two types of nodes and a transmission node are also transmitted through different channels. The control plane node and the user plane node interact with each other through an Xn interface. The transmission nodes can be connected with the control plane nodes and the user plane nodes independently, or a plurality of transmission nodes form a pool or a cluster which is connected with the control plane nodes and the user plane nodes; and the functionality of the user plane node may also be moved down to the transport node in whole or in part.
The control plane node at least comprises the following functions: service identification, resource coordination and allocation management, physical layer mechanism selection, control signaling processing including control signaling sending and receiving, and the like.
The user plane node comprises at least the following functions: processing of user data (including transmission and reception of data, determination of data scheduling policies), data compression, data encryption, segmentation, concatenation, re-segmentation, re-concatenation, ordering, ARQ, etc.
The transmission node comprises at least the following functions: interference mitigation or cancellation, large-scale spatial diversity, additional infrastructure nodes and/or inter-node cooperation, hybrid automatic repeat request (HARQ), determination of frame structure (including determination of subcarrier spacing, cyclic prefix, subframe, sampling frequency), scrambling, modulation, layer mapping, precoding, and the like.
Step 102: and selecting the second node meeting the transmission requirement of the service type according to the service type in the service request and the transmission capability indication information of the second node.
And sending the service data corresponding to the service request of the user terminal to the corresponding user terminal through the second node. Different service requests may carry different service types, and transmission capabilities required by different service types are different. Further, the transmission capabilities of different nodes are different. Specifically, when the user terminal initiates a service request, the first node selects a node satisfying the transmission requirement of the service type from the second node to establish a connection according to the service type in the service request and the transmission capability indication information of the second node. For example: if the service type requested by the user terminal has the requirement of low-delay transmission, selecting a second node with low-delay transmission capability to establish connection with the first node; if the service type requested by the user terminal has the transmission requirement with high reliability, selecting a second node with high reliability transmission capability to establish connection with the first node; or, if the service type requested by the user terminal requires low delay and high reliability at the same time, selecting a second node with low delay and high reliability transmission capability to establish a connection with the first node. After the connection is established, service data corresponding to a service request of the user terminal is sent to the corresponding user terminal through a second node, wherein the service data carries user plane node information and transmission node information, and the user plane node information at least comprises a user plane identifier and allocated user plane resource information; the transmission node information comprises at least a transmission node identification and allocated resource information.
Therefore, the transmission capability indication information of the second node which belongs to the same access network as the first node is obtained, and the corresponding second node is selected according to the transmission requirement of the service type in the service request, so that the service transmission requirement of the user terminal is met, and the user experience is improved.
Example two
The above embodiment briefly introduces the node selection method of the present invention, and the following embodiment will further explain the node selection method based on the first embodiment and with reference to a specific application scenario.
The step S101 of acquiring the transmission capability indication information of the second node in the same access network as the first node at least includes the following two ways:
the first method is as follows: and receiving respective transmission capability indication information actively reported by all second nodes in the same access network with the first node.
The method is a passive acquisition method, and the second node actively reports the transmission capability indication information supported by the second node to the first node, so that the first node selects a node meeting the service transmission requirement according to the service request of the user terminal for transmission. That is, the transmission node or the user plane node sends the transmission capability indication information (e.g., low latency or high reliability capability indication information) supported by itself to the control plane node.
The second method comprises the following steps: transmitting transmission capability request information to a second node under the same access network; and receiving transmission capability indication information of the second node itself, which is transmitted according to the transmission capability request information.
The method is an active acquisition method, and the first node actively inquires the transmission capability of the second node. Specifically, the first node sends the transmission capability request information to the second node in the following two cases: one is that when the control plane node sends transmission capability request information to the user plane node or the transmission node, the request information carries a user plane node identifier or a transmission node identifier, that is, the first node sends transmission capability request information to the designated second node, and then the designated second node feeds back transmission capability indication information of itself, and the other second nodes do not respond. The second is that, when the control plane node sends transmission capability request information to the user plane node or the transmission node, the request information does not carry a user plane node identifier or a transmission node identifier, that is, the first node sends transmission capability request information to all the second nodes learned by itself, and then all the second nodes all feed back their transmission capability indication information to the first node, where the second nodes include information of the control plane node itself or information of other transmission nodes or user plane nodes in a pool or cluster where the control plane node is located, or information of other transmission nodes or user plane nodes associated with the control plane node.
Further, the transmission capability indication information at least includes: time delay and reliability.
The delay and the reliability are respectively carried to different cells to indicate, namely the delay is indicated by a first cell, the reliability is indicated by a second cell, and the first cell is different from the second cell. Specifically, when the values of different cells are all the first values, the corresponding second node is indicated to have low-delay and high-reliability transmission capability; wherein, the first value can be set to a positive value such as "1" or "true"; that is, when the values of the first cell and the second cell are both "1" or "true", it indicates that the corresponding second node has both low latency transmission capability and high reliability transmission capability. When the values of different cells are the second values, indicating that the corresponding second node does not have the transmission capability with low time delay and high reliability; the second value is different from the first value, and can be set as a negative value such as '0' or 'false'; that is, when the values of the first cell and the second cell are both "0" or "false", it is indicated that the second node has neither low latency transmission capability nor high reliability transmission capability. When only one value in different cells is a first value, indicating that the corresponding second node only has one transmission capability of low time delay or high reliability; when only the first cell takes the value of '1' or 'true', indicating that the second node only has low delay transmission capability and does not have high reliability transmission capability; and when only the second information element takes the value of '1' or 'true', indicating that the second node only has high-reliability transmission capability and does not have low-delay transmission capability.
Besides carrying the delay and the reliability into different cells respectively for indication, the delay and the reliability can also be carried into the same cell for indication, namely, the delay and the reliability are indicated by a third cell. Specifically, when the value of the same cell is the third value, the corresponding second node is indicated to have only low-delay or high-reliability transmission capability; the third value may be set to be a referring value such as "only" or "only", that is, when the third cell takes on the value of "only" or "only", the third value indicates that the corresponding second node has only a low latency transmission capability or only a high reliability transmission capability, and specifically indicates which transmission capability may be defined in advance in the cell standard. When the value of the same cell is a fourth value, indicating that the corresponding second node has low-delay and high-reliability transmission capability; the third value and the fourth value have different values, and the fourth value can be set to be a general value such as "both" or "average", that is, when the value of the third cell is "both" or "average", the corresponding second node is indicated to have both low-delay transmission capability and high-reliability transmission capability. And when the third cell carrying the transmission capability indication information does not exist, indicating that the corresponding second node has neither low-delay transmission capability nor high-reliability transmission capability.
The delay and the reliability are carried into the indication in the same cell, except the indication mode, the following mode can be adopted: carrying the delay to a low order or high order indication in the cell; reliability is carried to the high or low indication in the same cell. For example: the indication cell has two bits, the lower bit is used for indicating time delay, the upper bit is used for indicating reliability, if the value of the indication cell is '00' or the indication cell does not contain the cell, the corresponding second node does not support low time delay transmission capability or high reliability transmission capability; if the value is 01, the corresponding second node only supports the low-delay transmission capability and does not support the high-reliability transmission capability; if the value is '10', the second node does not support low-delay transmission capability and high-reliability transmission capability; if the value is '11', the second node supports both low-delay transmission capability and high reliability. Or, vice versa, that is, the lower bit is used to indicate reliability, the upper bit is used to indicate delay, and if the indication cell takes the value of "00" or does not contain the cell, it indicates that the second node does not support low delay transmission capability or high reliability transmission capability; if the value is 01, the second node supports high-reliability transmission capability and low-delay transmission capability; if the value is '10', the second node does not support high-reliability transmission capability and low-delay transmission capability; if the value is '11', it indicates that the second node supports both low-latency transmission capability and high-reliability transmission capability.
In summary, the transmission capability of the second node in the same access network is obtained through different cell indication modes and different reporting modes, so that the first node can select the corresponding second node according to the transmission capability required by the service type in the service request of the user terminal, thereby satisfying the service transmission requirement of the user terminal and improving the user experience.
