Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a signal relay transmission method, a device, equipment and a readable storage medium, which are used for solving the problem that the existing relay technology can reach the destination of an actual terminal after going through a relay core network, and the change of the core network of the existing network is influenced.
Referring to fig. 1, fig. 1 is a flowchart of a signal relay transmission method provided in an embodiment of the present invention, where the signal relay transmission method is applied to a base station node, and as shown in fig. 1, the method includes the following steps:
the relay means that the base station node or the user node does not directly send signals to each other, but forwards the signals after corresponding processing through the relay node.
In this embodiment, the starting point of the first bearer path is a network element (MME), a port Un of the relay node is added midway, and the first bearer path is terminated at a User node (UE). In a complete signal transmission network, a core network, a base station node and a user node are required to be included, and in a core network, a plurality of network elements are included, and each network element can be connected with a plurality of user nodes.
It should be noted that, before the first bearer path is established, a network path for transmitting signals needs to be generated, for a 4G network, the generated path information is shown in fig. 2, the path information in fig. 2 includes a User node UE, a 4G base station node eNB, a Serving GateWay (S-GW), a GateWay PGW, a Peer Entity and a connection path between nodes, and for a 5G network, the generated path information is shown in fig. 3, the path information in fig. 3 includes a User node UE, a 5G base station node, a User Port Function (User NB Function, UPF) and a connection path between nodes, where the path information of the 4G network and the path information of the 5G network are consistent with the existing one, and no further description is given here. In the present application, as shown in fig. 4-5, signal coverage in the network is enhanced by adding a relay node between the user node and the base station node. It is worth pointing out that, after a relay node is added between a user node and a base station node, a radio bearer is added in a network, the radio bearer connects the base station node and the relay node, specifically, the relay node is connected with the user node through a port Uu, and the relay node is connected with the base station node through a port Un.
102, sending a scheduling instruction to the relay node based on the first bearer channel, wherein the scheduling instruction is used for indicating target information needing to be uploaded by the user node;
specifically, the target information includes uplink data and downlink data that the base station node needs to acquire. In this embodiment, when the base station node is to schedule information on the user node, a scheduling instruction is first sent to the relay node. For example, if the base station node needs to acquire data of the user a and the user B, the base station node generates a scheduling instruction for instructing to schedule the data of the user a and the user B, and sends the scheduling instruction to the relay node, and the relay node acquires the data of the user a and the user B in the user node based on the scheduling instruction and sends the acquired data of the user a and the user B to the base station node. And 103, receiving target information from the relay node based on the first bearing channel.
It should be noted that the first bearer channel includes two segments, which are a first segment channel and a second segment channel respectively, where the first segment channel is a channel from the gateway to the relay node, and the second segment channel is a channel from the relay node to the user node.
According to the signal relay transmission method, the network element starting from the core network is established, the port Un of the relay node is accessed and terminated at the first bearing channel of the user node, and the scheduling instruction is sent to the relay node based on the first bearing channel so as to acquire the target information to be transmitted by the user node.
Optionally, the establishing a first bearer path starting at the network element and passing through the port Un of the relay node and terminating at the user node includes:
respectively acquiring a first ip address of each gateway, a second ip address of a relay node and a third ip address of a user node;
and establishing a first bearing channel based on the first ip address, the second ip address and the third ip address.
In this embodiment, the first bearer channel is established based on ip addresses. Specifically, the core network acquires a first ip address of a gateway, a second ip address of a relay node and a third ip address of a user node in the network, and further establishes a first bearer channel based on the first ip address, the second ip address and the third ip address, so that an accurate and stable first bearer channel can be established based on the ip addresses.
Alternatively, since the network may further include a user port function, a service gateway or other nodes, in other possible embodiments, the channel information may further include an ip address of the user port function or the service gateway, so as to establish a corresponding channel related to the user port function or the service gateway. The present invention is described by way of example only, and not by way of limitation, and is within the scope of the present invention regardless of the modifications made thereto.
Optionally, after the first bearer path starting at the network element and passing through the port Un of the relay node and terminating at the user node is established, and before the scheduling instruction is sent to the relay node based on the first bearer path, the method further includes:
acquiring a port Un of a relay node;
a first radio bearer is established with the relay node based on the port Un.
It is worth emphasizing that the relay node is connected with the user node through a port Uu, and the relay node is connected with the base station node through a port Un. In order to facilitate signal transmission between the base station node and the relay node, a first radio bearer between the base station node and the relay node needs to be established.
Optionally, the relay node includes a terminal Uu, a second radio bearer is included between the port Uu and the user node, and a holding time of the first radio bearer is longer than a holding time of the second radio bearer.
The first radio bearer may be statically allocated, semi-statically allocated, or dynamically allocated, but no matter what allocation method is adopted, it is required to ensure that the retention time of the first radio bearer is longer than that of the second radio bearer, so that the first radio bearer in the relative uplink may not end before the second radio bearer in the relative downlink ends, and the stability of signal transmission in the network may be ensured. It is noted that the second rb is a second segment of the first bearer channel.
Optionally, before sending the scheduling instruction to the relay node based on the first bearer channel, the signal relay transmission method further includes:
and acquiring a mapping relation between the relay node and the user node.
In this embodiment, there is a mapping relationship between the user node and the relay node, based on which the user node attaches the actual user data to the relay node. In this way, the base station node may obtain the actual user information of the user node by scheduling the relay node.
Optionally, the sending the scheduling instruction to the relay node based on the first bearer channel includes:
and sending a scheduling instruction to the relay node based on the first bearing channel and the mapping relation so as to schedule the relay node.
Without loss of generality, when the base station node schedules the relay node, the relay node is marked first, and the priority of the relay node is set to be relatively high, for example, the scheduling priority of the relay node is set to be 1, and the scheduling priorities of the other nodes which are not the relay node are set to be 2, wherein the priority 1 is higher than the priority 2.
Then, the base station node and the relay node interact with the respective attached terminal information, such as user information, where the terminal information includes a terminal context and a Cell-radio network temporary identifier (C-RNTI) of an actual terminal. Understandably, the terminal information is stored on both the base station node and the relay node. In order to enable the base station node and the relay node to perform information interaction normally, interface information of the relay device needs to be newly added in an S1 interface and an X2 interface, so that the base station node and the relay node follow the same signal transmission protocol to perform information interaction, and the S1 interface adopts short-delay periodic scheduling or special channel transmission, so that interaction delay can be reduced, and the rate of information interaction can be improved. The S1 interface is an interface between the base station and the core network, and the X2 interface is an interconnection interface between the base stations.
In this embodiment, in the process of downward scheduling information, the base station node preferentially schedules a relay node with a high priority, and sends a scheduling instruction to the relay node based on the first radio bearer, in the scheduling process, the base station node acquires the relay node and actual terminal data attached to the relay node through an S1 interface, and the base station node schedules data on the relay node at a Un air interface, where the data is other actual terminal data attached to the relay device.
Optionally, before sending the scheduling instruction to the relay node based on the first bearer channel, the method further includes:
distinguishing user data information belonging to the relay node from user data information not belonging to the relay node based on the filter layer SDAP;
and generating the scheduling instruction based on the user data information belonging to the relay node.
In a 5G network, as shown in fig. 6, fig. 6 includes several filtering layers, such as a filtering layer SDAP, a filtering layer PDCP, a filtering layer RLC, and a filtering layer MAC, when using relay technology for scheduling, as shown in fig. 7, a first-level scheduling is performed between a base station node and a relay node, a second-level scheduling is performed between the relay node and the base station node, the base station node distinguishes the relay node and user data attached to the relay node during the first-level scheduling, the user data attached to the relay node is transmitted through the relay node, the base station node performs one-time scheduling on all the user data attached to the relay node, at this time, the filtering layer is required to implement enhanced functions, such as performing a mapping function of the relay node and the user data attached to the relay node, after the relay node receives the user data, scheduling an actual terminal, and scheduling the terminal again at Uu port, and multi-stage data transmission is realized.
For example, for user Data information a, user Data information B, user Data information C, and user Data information D that a base station node needs to call, where the Data information a, the user Data information B, and the user Data information C belong to information corresponding to a user under a relay node, the user D does not belong to information corresponding to a user under a relay node, the base station node first distinguishes, by a filter layer SDAP (Service Data attachment Protocol, SDAP), that the Data information a, the user Data information B, and the user Data information C are a set of Data information that needs to be called, and the user Data information D is another set of Data information that needs to be called. And generating scheduling instructions of scheduling data information A, user data information B and user data information C, sending the scheduling instructions to the relay nodes, analyzing the scheduling instructions by the relay nodes and scheduling corresponding data information, and then performing one-time scheduling by taking all data information as data of the relay nodes.
Therefore, multi-level scheduling can be realized through the base station node without changing channel information, mapping from multiple users (actual terminals) to a single user (relay node) is realized through the enhanced function of the filter layer SDAP, and the relay node is scheduled through the Un port to carry actual terminal data. The relay node receives the data and transmits the data to the actual terminal again after demodulating the data, thereby avoiding the change of a core network, simplifying the relay function and realizing the coverage enhancement of signals and the capacity improvement of cells.

in this embodiment, the starting point of the first bearer path is an MME network element, a port Un of the relay node is added midway, and the first bearer path is terminated at a User node (UE). In a complete signal transmission network, a core network, a base station node and a user node are required to be included, and in a core network, a plurality of gateways are included, each gateway can be connected with a plurality of user nodes, so that when a first bearer channel is established, a plurality of first bearer channels starting from the gateway and ending at the user nodes can be established, and thus, each user node can be connected to the gateway of the core network.
In this embodiment, when the base station node is to schedule information on the user node, a scheduling instruction is first sent to the relay node. For example, if the base station node needs to acquire data of the user a and the user B, the base station node generates a scheduling instruction for instructing to schedule the data of the user a and the user B, and sends the scheduling instruction to the relay node, and the relay node acquires the data of the user a and the user B in the user node based on the scheduling instruction and sends the acquired data of the user a and the user B to the base station node.
and 203, sending the target information to the base station node based on the first bearing channel.
