The specific configuration of the data forwarding device working mode and the specific implementation manner of the device according to the embodiment of the present invention are described in detail below with reference to the accompanying drawings.

The data forwarding device provided by the embodiment of the present invention may be a base station or a user equipment UE under the coverage of the base station. The base station may be a low-power website or a small station. The control node provided by the embodiment of the present invention may be a physical node or a logical node, and may be implemented by a macro base station.

The data forwarding device is exemplified as a base station. First, the working mode mentioned in the embodiment of the present invention is described. The working mode of the base station can be divided into the following types according to the forwarding data type: the L1 forwarding mode, and the base station can be used as a kind Layer 1 (physical layer L1) website. For the downlink data transmission, the processed physical layer data is received from the upper node of the base station (for example, the local data center, the Serving Gateway), and then on the empty intermediate plane, Sending the physical layer data to the UE as the transit of the downlink data transmission; or, for the uplink data transmission, receiving the data from the UE, the data is the physical layer data, and then directly transmitting the physical layer data to the upper node of the base station. The high-level node processes the physical layer data by the high-level node of the upper-level node of the base station, and then sends it to the higher-layer node as the transit of the uplink data transmission.

In the L2 forwarding mode, the base station can serve as a layer 2 (L2, for example, access control MAC, radio link control RLC, or packet data aggregation protocol PDCP) website. For downlink data transmission, L2 data is received from the upper node of the base station. Then, the received L2 data is processed, for example, the received L2 data is processed into physical layer data, and then the physical layer data is sent to the UE on the empty intermediate plane as a transit of downlink data transmission; or, for uplink Data transmission, receiving data from the UE, the data is the physical layer data, and processing the data, for example, processing the physical layer data into L2 data, and then transmitting the L2 data to the upper node of the upper node of the base station, by the base The high-level node of the upper node of the station processes the L2 data and then sends it to the higher-level node.

In the L3 forwarding mode, the base station can act as a layer 3 (L3, for example, IP layer) website. For downlink data transmission, the IP data packet is received from the upper node of the base station, and then the IP data packet is processed, for example, the IP data is processed. The packet is processed as the physical layer data, and then the physical layer data is sent to the UE on the empty intermediate plane as the transit of the downlink data transmission; or for the uplink data transmission, the data is received from the UE, that is, the physical layer data, and the physical layer data The processing is performed, for example, the physical layer data is processed into IP data, and then the IP data is transmitted to the upper node of the upper node of the base station, and the high-level node of the upper node of the base station performs forwarding and addressing operations on the IP data.

Of course, the type of data forwarded by the base station is divided, and the working mode of the base station The formula includes: an L1 forwarding mode, an L2 forwarding mode, and an L3 forwarding mode. It should be understood by those skilled in the art that the working mode of the base station can also be divided from other angles, for example, the base station can work in a compatible mode, that is, Supports modes of low-end devices (including network devices and terminal devices) to support dual connectivity with macro base stations; base stations can also work in non-compatible mode, ie, cannot support lower-level devices (including network devices) And the mode of the terminal device, for example, the base station does not send a normal public signaling broadcast, etc., and is invisible to the idle state (IDLE) UE, and only the connected UE can use the base station resource to perform data under the control of the network. transmission.

As shown in FIG. 1 , the method includes: Step 102: The data forwarding device and the control node negotiate an operation mode of the data forwarding device. The data forwarding device determines the working mode of the data forwarding device according to the negotiation result.

In the configuration method provided by the embodiment of the present invention, the working mode of the data forwarding device is negotiated between the data forwarding device and the control node, and the working mode of the data forwarding device is determined according to the negotiation result, so that the data forwarding device can flexibly select the working mode, and In the prior art, the working mode of the access node has been determined before the access node is deployed, and the working mode is flexibly selected according to the flexible selection of the working mode in the working process, so that the data forwarding device works in the most suitable working mode. The flexibility of the road to better respond to changes in network resource status and traffic changes, and improve network communication efficiency.

In the specific implementation, when the base station is powered on or restarted, for example, when the base station is initially deployed or the base station is turned off after other reasons (for example, power saving), The base station adopts the operation of newly joining the network, and the base station negotiates the working mode of the base station with the control node, and determines the working mode of the base station according to the current backhaul link configuration of the base station and the network state. The control node may be pre-stored in the base station, or may be found by the base station according to an algorithm. For example, the base station may interact with the surrounding base station to acquire a control node, and the control node may be a single entity or the same The covered macro base station can also be the upper hop access anchor point of the base station on the side close to the network.

In an optional implementation manner, in the configuration method provided by the embodiment of the present invention, the working mode of the data forwarding device includes: an L1 forwarding mode, an L2 forwarding mode, and an L3 forwarding mode, where the data forwarding device is in the L1 forwarding mode. The L1 data is forwarded between the UE and the upper node of the base station. In the L2 forwarding mode, the data forwarding device forwards the L2 data between the UE and the upper node of the base station. In the L3 forwarding mode, the data forwarding device is at the upper level of the UE and the base station. Forward L3 data between nodes.

In an optional implementation manner, the data forwarding device negotiates the working mode of the data forwarding device with the control node, where the data forwarding device sends a working mode configuration request to the control node, and the data forwarding device receives the working mode sent by the control node. And the data forwarding device determines the working mode of the data forwarding device according to the negotiation result, where the data forwarding device determines the working mode indicated in the working mode configuration command as the working mode of the data forwarding device.

In an optional implementation manner, in the configuration method provided by the embodiment of the present invention, the working mode configuration request includes one or any combination of the following information: capability information of the working mode supported by the data forwarding device, and data forwarding device support The preference information of the work mode and the priority information of the work mode supported by the data forwarding device.

In an optional implementation manner, in the configuration method provided by the embodiment of the present invention, before the data forwarding device sends the working mode configuration request to the control node, the method further includes: the data forwarding device sending one or the following information to the control node Combination: capability information of the working mode supported by the data forwarding device, preference information of the data forwarding device for the supported working mode, and priority information of the working mode supported by the data forwarding device.

In a specific implementation, the base station sends the capability information of the working mode supported by the base station, the preference information of the base station to the supported working mode, and the priority information of the working mode supported by the base station to the control node, requesting the control node. The working mode is configured for the base station, wherein the capability information of the working mode supported by the base station includes: a software version supported by the base station, a configuration of a backhaul link of the base station, and a measurement result of the base station to the surrounding situation, for example, a base station Received signals and interference power at various frequencies can be measured.

When the control node selects the working mode for the base station, the following principles are followed:

First, the working mode can only be selected in the working mode supported by the base station.

Second, consider the actual physical state of the base station backhaul configuration. For example: wired or wireless, if it is wired, it is fiber, any subscriber line (Digital Subscriber Line, xDSL), or something else. Generally, the backhaul configuration bandwidth required for the lower layer forwarding needs to be smaller, that is, the L1 forwarding mode needs a backhaul configuration with a larger bandwidth and a more severe delay, and the backhaul configuration required for the L3 forwarding mode is required. The feature is relatively loose, and the L2 forwarding mode is between the two. The wireless backhaul configuration is not suitable for selecting the L1 forwarding mode because of the limited bandwidth and long delay. Moreover, because the control is not flexible and is not suitable for the base station in the incompatible mode, it needs to be selected in other modes; generally, point-to-point Fiber optic backhaul configuration is ideal for fast bandwidth due to bandwidth and latency. Coordinating and satisfying the conditions of the L1 forwarding mode, therefore, the base station with this backhaul configuration can basically select all the working modes, but the fiber backhaul configuration is only a hardware setting, usually in the case of a switch, router or gateway processing. In this case, the actual transmission bandwidth of the backhaul configuration is also limited by the processing speed of the switch, router or gateway, and cannot reach the physical limit transmission rate. For example, the physical transmission rate of the optical fiber may be 10 Gbps, but the transmission rate of the link may be only 10 Mbps, and the actual transmission rate of the backhaul configuration is only 10 Mbps. Therefore, it is necessary to comprehensively consider the physical characteristics and resource configuration characteristics of the backhaul configuration, and consider the mode selection by using the smaller values of the two as the backhaul configuration characteristics.

3. The node that is connected to the base station and is responsible for processing the data of the base station, and whether the processing load allows the access of the new base station. For example, if the base station needs to work in the L1 forwarding mode, then a high-level node needs to process the service data into L1 data. This process requires processor support. When many base stations select this mode, it is possible that the node Processing power will reach the upper limit, so that new base stations cannot be admitted.

Fourth, consider the situation of other base stations around the base station. For example, within the scope of cooperation, the neighboring base stations work in the L1 forwarding mode. If the newly added base station allows conditions such as backhaul configuration, the L1 forwarding mode can also be selected to join the cooperation scope and increase the efficiency of the null intermediate plane.

As a more specific embodiment, when the actual transmission bandwidth configured by the base station backhaul can reach the threshold X1, the transmission delay is less than the threshold M1, and the capability of the high-level node of the base station allows a new base station to work in the L1 forwarding mode, and the upper layer The node has a good grasp of the transmission situation of the surrounding base stations, and the centralized scheduling is more conducive to the system performance. The working mode of the ground station is selected as the L1 forwarding mode; when the actual transmission bandwidth capability of the base station backhaul cannot meet the threshold X1 requirement, and the transmission delay is greater than the threshold X2 requirement, the transmission delay is greater than M1 is less than M2, and the base station itself processes And the storage capacity can meet the requirements of the L2 forwarding mode. From the existing working mode of the surrounding base station, a base station operating in the L2 forwarding mode is more conducive to the improvement of the overall efficiency, and the working mode of the base station can be selected as L2. Forwarding mode; when the actual transmission capacity of the base station backhaul configuration is lower than the threshold X2 requirement, the transmission delay is greater than M2, and the processing and storage capacity of the base station itself can meet the requirements of the L3 forwarding mode, or the base station has its own characteristics. For example, if the Close Subscriber Group (CSG) community needs to work independently, then the working mode of the base station can be selected as the L3 forwarding mode, where X1 is greater than X2 and M1 is less than M2.

The control node refers to a node or a logical control entity that negotiates the working mode of the base station with the base station, and the high-level node refers to a node or a logical control entity that needs to directly exchange data with the base station, and the control node and the high-level node may be located. Two nodes in the same entity (for example, a macro station) may also be nodes in different entities or different entities.

In an optional implementation manner, in the configuration method provided by the embodiment of the present invention, the data forwarding device negotiates the working mode of the data forwarding device with the control node, including: the data forwarding device determines an alternate working mode; and the data forwarding device Sending a working mode admission request to the control node, including the candidate working mode; the data forwarding device receives the working mode acceptance response message sent by the control node; and the data forwarding device determines the working mode of the data forwarding device according to the negotiation result, specifically: The data forwarding device determines the working mode of the data forwarding device according to the working mode acceptance response message sent by the control node.

In the specific implementation, the base station and the control node negotiate the working mode of the base station, The base station may request the control node to configure the working mode for the base station, or the base station may determine the candidate working mode, and send the candidate working mode to the control node, and the control node determines whether to accept the candidate working mode. .

As a more specific embodiment, the base station is powered on or restarted, and requests the relevant node to obtain current information. For example, if it is a wired backhaul configuration, it can be searched to the control entity of the switching device, and the rate that can be allocated to its own backhaul configuration is How big is the current load of the wired link, etc. It is also possible to obtain some necessary information from the adjacent base stations through the X2 interface or other similar interfaces, and the working mode of the adjacent base stations. The above information obtained by the base station (the rate of the backhaul configuration allocation and/or the working mode of the adjacent base station), combined with its own capabilities, selects a working mode that is most suitable for the alternative, after the base station determines the alternative working mode. And sending a working mode admission request to the control node, where the working mode admission request includes an alternate working mode, and determining a working mode of the base station according to the receiving response message replied by the control node. Among them, when the base station determines the alternative working mode, it also needs to follow the principle that the control node selects the working mode for the base station.

In an optional implementation manner, in the configuration method provided by the embodiment of the present invention, when the working mode admission response message indicates that the control node determines that the candidate working mode can be accepted, the data forwarding device accepts the response according to the working mode sent by the control node. The message determines that the working mode of the data forwarding device comprises: the data forwarding device determines an alternate working mode as an operating mode of the data forwarding device; and when the working mode admission response message indicates that the control node refuses to accept the candidate working mode, the data forwarding The device determines the working mode of the data forwarding device according to the working mode acceptance response message sent by the control node, and includes: when the working mode acceptance response message includes the working mode selected by the control node for the data forwarding device, the data forwarding device selects the control node The selected working mode is determined as the working mode of the data forwarding device; or the data forwarding device re-determines the alternate working mode and sends the working mode admission request to the control node again, including the re-determined alternative working mode, receiving The working mode accepts the response message sent by the control node again, and determines the working mode of the data forwarding device according to the working mode acceptance response message sent by the control node again.

In a specific implementation, after the base station sends the candidate working mode to the control node, the control node determines that the candidate working mode can be accepted, and sends an acceptance response message indicating that the control node determines that the candidate working mode can be accepted. To the base station, the base station determines an alternate mode of operation as the working mode; the control node refuses to accept the alternate mode of operation, and sends an admission response message indicating that the control node refuses to accept the alternate mode of operation to the base station, The message may include a working mode selected by the control node for the base station. If the control node selects the working mode selected by the base station, the base station determines the working mode selected by the control node for the base station as the working mode, if the control node is not included. For the mode of operation selected by the base station, the base station re-determines the alternate mode of operation and sends it to the control node to reconfirm whether to accept the re-determined alternative mode of operation.

As a more optional embodiment, when the base station determines an alternate working mode, if there are multiple alternative working modes, the base station may select multiple working modes according to the base station's preference information about the supported working mode. The most suitable working mode is used as an alternative working mode. The alternative working mode selected in this way can better utilize the configuration of the base station, but needs to be sent to the control node for confirmation, in order to improve the base station and control. The efficiency of the negotiation between the nodes is another optional embodiment. In the configuration method provided by the embodiment of the present invention, the candidate working mode includes multiple working modes; the working mode receiving response message includes The control node selects a working mode selected by the data forwarding device from the multiple working modes; the data forwarding device determines the working mode of the data forwarding device according to the working mode acceptance response message sent by the control node, and includes: the data forwarding device controls the node The working mode selected for the data forwarding device is determined as the working mode of the data forwarding device.

Certainly, when the base station sends multiple candidate working modes to the control node, the base station may also be arranged in a certain priority order to indicate that the control node selects the working mode of the base station in the multiple candidate working modes according to the order. Make a choice.

In an optional implementation manner, after the data forwarding device determines the working mode of the data forwarding device according to the negotiation result, the data forwarding device further includes: the data forwarding device receives the working mode sent by the control node. The configuration instruction; the data forwarding device switches the currently employed working mode to the working mode indicated in the working mode reconfiguration command.

In the specific implementation, after the base station determines the working mode, that is, in the working process of the base station, due to the change of the network state, in order to provide better service and improve the efficiency of the whole system, the control node may work on the base station. The mode is reconfigured, and a reconfiguration command is sent to the base station, indicating that the base station switches the working mode to the working mode indicated in the reconfiguration command without affecting the UE as much as possible.

Specifically, the change of the network state includes: the configuration of the base station backhaul link is redistributed, causing the base station's backhaul link rate to change, for example, the rate of the backhaul link is 10 megabits (Mbps). Change to 1 Mbps or change from 1 Mbps to 10 Mbps; the processing load of the high-level node connected to the base station changes; the working mode of the adjacent base station around the base station changes; the service load of the base station changes; the service of the empty intermediate plane The demand has changed; it is not satisfied with the previous service.

As a more specific embodiment, due to the tidal effect of the business, the business volume of the office building area during the day is large, and the business volume of the residential area at night is large. When the business volume is reduced, the base station can adopt a more power-saving working mode or even shut down, backhaul The configured resources are also relatively rich. At this time, the base station that is still in the working state can switch the working mode according to the situation, so as to be more suitable for the current business situation and improve efficiency.

In an optional implementation manner, after the data forwarding device determines the working mode of the data forwarding device according to the negotiation result, the data forwarding device further includes: when the data forwarding device determines that the working mode needs to be switched, The operating mode of the data forwarding device is negotiated with the control node, and the current working mode is switched according to the negotiation result.

In a specific implementation, when the network status changes, the base station can renegotiate the working mode with the control node, send the alternate working mode to the control node, and the control node performs the receiving or selecting process to re-determine the working mode of the base station. The base station switches the working mode without affecting the UE as much as possible to provide better service and improve the efficiency of the entire system.

Of course, in the specific implementation, when the base station switches the working mode, the mode switching between the base station and the upper node is required to be synchronized. In short, the base station and the upper node need to switch from the old mode to the new mode at the same time, for example: Before the handover is the L1 forwarding mode, then the L1 data is transmitted between the two, and the L2 forwarding mode is transmitted after the handover. The L2 data is transmitted between the two, and the base station and the upper node need to identify the data packet without any error. come out. Therefore, the base station switching mode of operation and the operation mode of the base station of the high-level node change record need to be synchronized.

As a more specific embodiment, a synchronous handover mode is an absolute time point of a predetermined handover, and before the absolute time point, both the base station and the upper node adopt an old working mode. Interact and switch to the new working mode at the same time and after the absolute time.

As another more specific embodiment, another synchronous handover manner is performed by the transmitting party, before the start of the new conversation mode, signaling the other party to end the old mode to start a new mode, for example, for downlink data transmission, It is sent by the high-level node to the base station, then the high-level node decides when to switch. It can add the end marker-like mark or signaling at the end of the old data packet, or add the start marker tag or signaling at the beginning of the new data. Similarly, uplink data transmission can also be marked by the base station. The two nodes may have a certain order. For example, after receiving the conversion signaling of the upper node, the base station retransmits the conversion signaling, or after receiving the conversion signaling of the base station, the upper node sends the conversion signaling again. There can be no order.
