Description

Method and device for configuring working mode of data forwarding equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring a working mode of a data forwarding device.

Background

In a Long Term Evolution (LTE) system, nodes on a network side are mostly connected by wires, that is, evolved Node bs (enbs) are connected by wire links, and the enbs and core network nodes are, for example: a Mobile Management Entity (MME), a Serving Gateway (S-GW), and the like, which are connected by a wired link.

In the research of Small cell (Small cell) enhancement, a dual-connection architecture is proposed, that is, a User Equipment (UE) maintains connection with a macro base station and also maintains connection with a Small station (a base station within the coverage of the macro base station), and performs wireless transmission by using resources of two stations.

In the prior art, the operation mode of the base station is a relatively static selection, and before the base station is deployed, the operation mode of the base station is basically determined by network planning, and the attributes of the base station are determined, for example: this is a relatively static process, although operation, administration and Maintenance (OAM) of a macro base station, a Relay node (Relay) or a Radio Remote Head (RRH) may configure and adjust operation parameters to some extent.

In the future development of mobile communication systems, in order to better meet user requirements and greatly improve network capacity and throughput, more low-power and small-coverage access nodes are inevitably introduced, i.e. in the future, ultra-dense networks are required. With the increase of low power access nodes, the network morphology will be more complex, the deployment situation of such access nodes is more diversified, the forms of backhaul links (backhaul) are also diversified, if the access node adopts the existing method of single working mode, it will not be able to maximize the network efficiency, nor be beneficial to cope with various changes of data traffic, such as tidal effect, etc., and the failure of the access node to work in the optimal state will inevitably affect the communication efficiency of the whole network and the user experience.

In summary, with the increase of access nodes in the future, determining the working mode of the access node before the deployment of the access node will certainly not maximize the network efficiency, which is not beneficial to dealing with various changes of data services and affecting the communication efficiency of the whole network.

Detailed Description

The following describes in detail specific embodiments of a method and an apparatus for configuring an operating mode of a data forwarding device according to an embodiment of the present invention with reference to the accompanying drawings.

The data forwarding device provided by the embodiment of the present invention may be a base station, or may also be a user equipment UE under the coverage of the base station, and the base station may be a low power station, or may also be referred to as a small station. The control node provided by the embodiment of the invention can be a physical node or a logic node, and can be specifically realized by a macro base station.

In the following, a data forwarding device is taken as a base station for example, and first, an operation mode mentioned in the embodiment of the present invention is described, where the operation mode of the base station may be divided according to types of forwarding data as follows:

in L1 forwarding mode, the base station can act as a layer one (physical layer L1) station. For downlink data transmission, receiving processed physical layer data from a network side, and then sending the physical layer data to UE on an air interface as the transfer of the downlink data transmission; or, for uplink data transmission, receiving data from the UE, where the data is physical layer data, then directly transmitting the physical layer data to a network side high-level node, where the physical layer data is processed by the network side high-level node and then transmitted to the higher-level node as a relay for uplink data transmission.

In the L2 forwarding mode, the base station may act as a layer two (L2, e.g., access control MAC, radio link control RLC, or packet data convergence protocol PDCP) station, and for downlink data transmission, receive L2 data from the network side, and then process the received L2 data, for example: processing the received L2 data into physical layer data, and then sending the physical layer data to the UE on an air interface as the transfer of downlink data transmission; or, for uplink data transmission, data is received from the UE, where the data is physical layer data, and the data is processed, for example: and processing the physical layer data into L2 data, transmitting the L2 data to a network side high-level node, processing the L2 data by the network side high-level node, and then sending the L2 data to a higher-level node.

In the L3 forwarding mode, the base station may serve as a layer three (L3, for example, IP layer) station, for downlink data transmission, receive an IP packet from the network side, and then process the IP packet, for example: processing the IP data packet into physical layer data, and then sending the physical layer data to the UE on an air interface to be used as the transfer of downlink data transmission; or for uplink data transmission, data is received from the UE, that is, physical layer data, and the physical layer data is processed, for example: and processing the data of the physical layer into IP data, transmitting the IP data to a network side high-level node, and performing forwarding addressing and other operations on the IP data by the network side high-level node.

Of course, the data types forwarded by the base station are divided, and the operation modes of the base station include: l1 forwarding mode, L2 forwarding mode, and L3 forwarding mode, it should be understood by those skilled in the art that the operation modes of the base station can also be divided from other angles, for example: the base station can work in a compatible mode and supports double connection with the macro base station; the base station may also operate in a non-compatible mode, for example, the base station does not send normal common signaling broadcast, and the like, and is invisible to the IDLE-state (IDLE) UE, and only the connected-state UE may use the base station resource for data transmission under the control of the network.

On the base station side, a method for configuring an operating mode of a data forwarding device provided in an embodiment of the present invention, as shown in fig. 1, includes:

step 102, a data forwarding device and a control node negotiate the working mode of the data forwarding device;

and step 104, 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 invention, the working mode of the data forwarding device is negotiated between the data forwarding device and the control node, and then 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.

In specific implementation, when the base station is powered on or restarted, for example: when a base station is initially deployed or the base station is turned on after being turned off for other reasons (e.g., power saving), the base station takes an operation of newly joining a network, negotiates with a control node about a working mode of the base station, and determines the working mode of the base station according to a current backhaul link configuration condition and a network state of the base station. 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 can interact with surrounding base stations to acquire the control node, and the control node can be a single entity, can also be a macro base station covered with the base station, and can also be a last hop access anchor point of the base station and the like.

In a possible implementation manner, in the configuration method provided in 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, wherein the data forwarding device forwards L1 data between the UE and the network side in the L1 forwarding mode, forwards L2 data between the UE and the network side in the L2 forwarding mode, and forwards L3 data between the UE and the network side in the L3 forwarding mode.

In a possible embodiment, the data forwarding device negotiates an operation mode of the data forwarding device with the control node, and includes: the data forwarding equipment sends a working mode configuration request to the control node; the data forwarding equipment receives a working mode configuration instruction sent by the control node; the data forwarding device determines the working mode of the data forwarding device according to the negotiation result, specifically: and the data forwarding equipment determines the working mode indicated in the working mode configuration instruction as the working mode of the data forwarding equipment.

In a possible implementation manner, in the configuration method provided in the embodiment of the present invention, the configuration request of the operating mode includes one or a combination of the following information: capability information of the work modes supported by the data forwarding device, preference information of the data forwarding device for the supported work modes, and priority information of the work modes supported by the data forwarding device.

In a possible implementation manner, in the configuration method provided in the embodiment of the present invention, before the data forwarding device sends the operating mode configuration request to the control node, the method further includes: the data forwarding device sends one or a combination of the following information to the control node: capability information of the work modes supported by the data forwarding device, preference information of the data forwarding device for the supported work modes, and priority information of the work modes supported by the data forwarding device.

In specific implementation, a base station sends capability information of a working mode supported by the base station, preference information of the working mode supported by the base station, and priority information of the working mode supported by the base station to a control node, and requests the control node to configure the working mode for the base station, where the capability information of the working mode supported by the base station includes: software versions supported by the base station, backhaul link configuration conditions of the base station, and measurement results of the base station on surrounding conditions, for example: the base station can measure the received signal and interference power on each frequency point, and the like.

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

first, the operation mode can be selected only from the operation modes supported by the base station.

And secondly, considering the actual physical condition of the backhaul link (backhaul) configuration of the base station. For example: wired or wireless, and if wired, optical fiber, any Digital Subscriber Line (xDSL), or others. Generally, the lower-level forwarding requires larger bandwidth and smaller delay of the backhaul configuration, that is, the L1 forwarding mode requires backhaul configuration with larger bandwidth and more strict delay to support, while the L3 forwarding mode requires relatively more relaxed backhaul configuration characteristics, and the L2 forwarding mode is between the two modes. The wireless backhaul configuration is not suitable for selecting the L1 forwarding mode due to limited bandwidth and long time delay, and is not suitable for being used as a base station in an incompatible mode to work due to inflexible control and the need of selecting from other modes; generally, point-to-point optical fiber backhaul configuration is ideal in bandwidth and time delay, and is very suitable for fast coordination, and meets the conditions of an L1 forwarding mode, so that a base station with the backhaul configuration basically has all working modes selectable, but the optical fiber backhaul configuration is only a hardware configuration, and in a general case where a switch, a router or a gateway is required to process, the actual transmission bandwidth of the backhaul configuration is also limited by the processing speed of the switch, the router or the gateway, and cannot reach the transmission rate of a physical limit. For example: the physical transmission rate of the optical fiber may be 10Gbps, but due to the limitation of the switching device, the transmission rate allocated to the link may be only 10Mbps, and the actual transmission rate of the backhaul configuration is only 10 Mbps. Therefore, the physical characteristics and the resource allocation characteristics of the backhaul configuration need to be considered comprehensively, and the smaller value of the physical characteristics and the resource allocation characteristics is taken as the backhaul configuration characteristics to consider mode selection.

And thirdly, the node is connected with the base station and is responsible for processing the data of the base station, and whether the processing load of the node allows the access of a new base station or not is judged. For example: if the base station needs to work in the L1 forwarding mode, a higher-level node needs to process the service data into L1 data, the process needs the support of a processor, and when many base stations select the mode, the processing capacity of the node may reach the upper limit, so that a new base station cannot be admitted.

And fourthly, considering the situation of other base stations around the base station. For example: in the cooperative range, the adjacent base station works in the L1 forwarding mode, and if conditions such as backhaul configuration permit, the newly added base station can also select the L1 forwarding mode to join the cooperative range, thereby increasing the air interface efficiency.

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 higher node of the base station allows a new base station to work in the L1 forwarding mode, the higher node has better grasp on the transmission condition of the surrounding base stations, and the working mode of the base station can be selected to be the L1 forwarding mode under the condition that the centralized scheduling is more beneficial to the system performance; when the actual transmission bandwidth capacity configured by the base station backhaul cannot meet the requirement of a threshold X1 but is higher than the requirement of a threshold X2, and the transmission delay is greater than M1 and less than M2, and the processing and storage capacity of the base station per se can meet the requirement of an L2 forwarding mode, from the existing working mode of surrounding base stations, one base station working in an L2 forwarding mode is more beneficial to improving the overall efficiency, and the working mode of the base station can be selected to be an L2 forwarding mode; when the actual transmission capability of the backhaul configuration of the base station resists the requirement of the threshold X2 and the transmission delay is greater than M2, and the processing and storage capability of the base station itself can meet the requirement of the L3 forwarding mode, or the base station itself has characteristics, such as: a Closed Subscriber Group (CSG) cell needs to operate independently, and then the operation mode of the base station may be selected to be an L3 forwarding mode, where X1 is greater than X2, and M1 is less than M2.

The control node refers to a node or a logic control entity that negotiates the operating mode of the base station with the base station, the higher-level node refers to a node or a logic control entity that needs to directly perform data interaction with the base station, and the control node and the higher-level node may be two nodes located in the same entity (e.g., a macro station), or may be nodes in different entities or different entities.

In a possible implementation manner, in the configuration method provided in the embodiment of the present invention, a data forwarding device and a control node negotiate a working mode of the data forwarding device, where the method includes: the data forwarding equipment determines an alternative working mode; the data forwarding equipment sends a working mode admission request to a control node, wherein the working mode admission request comprises the alternative working mode; the data forwarding equipment receives a working mode admission response message sent by the control node; the data forwarding device determines the working mode of the data forwarding device according to the negotiation result, specifically: and the data forwarding equipment determines the working mode of the data forwarding equipment according to the working mode admission response message sent by the control node.

In specific implementation, the base station and the control node negotiate a 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 an alternative working mode and send the alternative working mode to the control node, and the control node determines whether to accept the alternative 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 the wired backhaul configuration is adopted, the control entity of the switching equipment can be searched, the rate of allocation can be configured for the backhaul of the control entity, the load of the current wired link is in what level, and the like; it is also possible to obtain some necessary information from the neighbouring base station, the operation mode of the neighbouring base station etc. via the X2 interface or other similar interfaces. The base station selects the most suitable alternative working mode according to the obtained information (the allocated rate of backhaul configuration and/or the working mode of the adjacent base station) by combining the capability of the base station, sends a working mode admission request to the control node after the base station determines the alternative working mode, wherein the working mode admission request comprises the alternative working mode, and determines the working mode of the base station according to an admission response message returned by the control node. When the base station determines the alternative working mode, the principle that the control node selects the working mode for the base station needs to be followed.

In a possible implementation manner, in the configuration method provided in the embodiment of the present invention, when the working mode admission response message indicates that the control node agrees to admit the alternative working mode, the determining, by the data forwarding device, the working mode of the data forwarding device according to the working mode admission response message sent by the control node includes: the data forwarding equipment determines the alternative working mode as the working mode of the data forwarding equipment; when the working mode acceptance response message indicates that the control node refuses to accept the alternative working mode, 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 the method comprises the following steps: when the working mode acceptance response message comprises the working mode selected by the control node for the data forwarding equipment, the data forwarding equipment determines the working mode selected by the control node as the working mode of the data forwarding equipment; or, the data forwarding device re-determines the alternative working mode, and re-sends the working mode admission request to the control node, where the working mode admission request includes the re-determined alternative working mode, receives a working mode admission response message sent again by the control node, and determines the working mode of the data forwarding device according to the working mode admission response message sent again by the control node.

In specific implementation, after the base station sends the alternative working mode to the control node, if the control node agrees to admit the alternative working mode, an admission response message for indicating that the control node agrees to admit the alternative working mode is sent to the base station, and the base station determines the alternative working mode as the working mode; and if the working mode selected by the control node as the base station is not included, the base station redetermines the alternative working mode and sends the working mode to the control node to redetermine whether to admit the redetermined alternative working mode.

As a more preferred embodiment, when the base station determines an alternative operating mode, if there are multiple alternative operating modes, the base station may select, according to preference information of the base station on the supported operating modes, a most suitable operating mode from the multiple operating modes as the alternative operating mode, and the alternative operating mode selected in this way may better utilize the configuration of the base station but needs to be sent to the control node for confirmation, so as to improve negotiation efficiency between the base station and the control node, as another more preferred embodiment, in the configuration method provided in the embodiment of the present invention, the alternative operating mode includes multiple operating modes; the working mode admission response message comprises a working mode selected by the control node from a plurality of working modes for the data forwarding equipment; the data forwarding device determines the working mode of the data forwarding device according to the working mode admission response message sent by the control node, and the method comprises the following steps: and the data forwarding equipment determines the working mode selected by the control node for the data forwarding equipment as the working mode of the data forwarding equipment.

Of course, when the base station sends the multiple candidate operating modes to the control node, the multiple candidate operating modes may be arranged in a certain priority order, so as to instruct the control node to select the operating mode of the base station in the multiple candidate operating modes according to the order.

In a possible implementation manner, in the configuration method provided in this embodiment of the present invention, after determining, by the data forwarding device according to the negotiation result, the operating mode of the data forwarding device, the method further includes: the data forwarding equipment receives a work mode reconfiguration instruction sent by the control node; and the data forwarding equipment switches the currently adopted working mode into the working mode indicated in the working mode reconfiguration instruction.

In specific implementation, after the base station determines the operating mode, that is, during the operation of the base station, due to a change in the network state, in order to provide a better service and improve the efficiency of the entire system, the control node may reconfigure the operating mode of the base station, and send a reconfiguration command to the base station, so as to instruct the base station to switch the operating mode to the operating mode indicated in the reconfiguration command without affecting the UE as much as possible.

Specifically, the change in the network status includes: the configuration of the backhaul link of the base station is reallocated, which causes the backhaul link rate of the base station to change, for example: the rate of the backhaul link is changed from 10 mega (M) to 1M or from 1M to 10M; the processing load of a high-level node connected with 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 requirements of the air interface change; the previous service is not satisfied.

As a specific embodiment, due to the tidal effect of the service, the service volume of the office building area is large in the daytime and the service volume of the residential area is large at night, when the service volume is reduced, the base station can adopt a more power-saving working mode, even turn off, resources configured by backhaul are more abundant, and the base station still in a working state can switch the working mode according to the situation, so as to be more suitable for the current service condition and improve the efficiency.

In a possible implementation manner, in the configuration method provided in this embodiment of the present invention, after determining, by the data forwarding device according to the negotiation result, the operating mode of the data forwarding device, the method further includes: when the data forwarding equipment determines that the working mode needs to be switched, the data forwarding equipment negotiates the working mode of the data forwarding equipment with the control node again, and switches the currently adopted working mode according to a negotiation result.

In specific implementation, when the network state changes, the base station may renegotiate the working mode with the control node, send the alternative working mode to the control node, and the control node performs admission or selection processing to re-determine the working mode of the base station, and the base station switches the working mode without affecting the UE as much as possible, so as to provide better service and improve the efficiency of the entire system.

Certainly, in the specific implementation, when the base station switches the working mode, the mode switching between the base station and the higher node needs to be synchronized, in a simple way, the base station and the higher node need to be switched from the old mode to the new mode at the same time, for example: before the switching, the L1 forwarding mode is adopted, L1 data are transmitted between the two, and after the switching, the L2 forwarding mode is adopted, L2 data are transmitted between the two, and the base station and the higher-level node need to be capable of identifying the data packet without errors. Therefore, the operation mode of the base station switching and the operation mode of the base station recorded by the upper node change need to be synchronized.

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

As another more specific embodiment, another way of synchronous switching is that the sending party signals the other party before the new interactive way starts, and the old mode is to be ended to start the new mode, for example: for downlink data transmission, the higher node sends the downlink data transmission to the base station, so that the higher node determines when to switch, and can add an endmarker-like mark or signaling at the end of an old data packet, or add a start marker mark or signaling at the beginning of new data. Similarly, uplink data transmission may also be marked by the base station. The two nodes may have a certain precedence order, for example: after receiving the switching signaling of the high-level node, the base station sends the switching signaling again, or after receiving the switching signaling of the base station, the high-level node sends the switching signaling again, or there may be no order.

And step three, the control node learns the capabilities and versions of the Donor UE 310, the surrounding measurement conditions, the capability and resource use conditions of the small station, the situation of the surrounding small stations grasped by the control node, the actual allocation situation of backhaul configuration and the like according to the reply of the small station or the interaction with the small station, selects a proper working mode for the Donor UE 310 by using a comprehensive algorithm (for example, a working mode selection principle), sends a configuration signaling to the Donor UE 310, and simultaneously needs to send the configuration signaling to the small station covering the Donor UE 310.
