Description

Technical Field

[0001] The present invention relates to the field of wireless technology, and in particular to a resource mapping method, device, base station unit and system. Background Art

[0002] In base station management, a basic content is the mapping and management of physical resources and logical functions of remote units. Physical resources refer to baseband processing resources, radio frequency processing resources, data exchange resources, data distribution and / or merging resources, etc. on remote units. Logical functions include logical cells, logical carriers, logical receiving and / or transmitting channels, etc.

[0003] For remote units connected based on Option 7-2 of the pure enhanced Common Public Radio Interface CPRI (enhanced-CPRI, eCPRI) protocol, in the existing base station technology, the physical resources of the remote units are pre-divided according to logical functions, and a corresponding extended antenna carrier identification e-AxCID is allocated to each physical resource. When transmitting data, the transmitter packages the data according to the eCPRI protocol, and the packet header includes an extended antenna carrier identification (Extended antenna carrier identification, e-AxCID, or eAxc-id / eaxc-id / e-axcid) field corresponding to the logical function; when processing data, the receiver parses the e-AxCID field in the packet header to determine the corresponding physical resources.

[0004] For remote units connected based on the Common Public Radio Interface (CPRI) protocol Option 8, in existing base station technology, all logical function information is configured to the remote units respectively. When transmitting data, the transmitter places the data at a specific position of the CPRI frame group according to the logical function information; after the receiver receives the data at a specific position of the CPRI frame group, it determines the corresponding physical resources according to the logical function information.

[0005] However, the above-mentioned mapping method of physical resources and logical functions of remote units is not suitable for base station systems with mixed networking of eCPRI protocol Option 7-2 division and CPRI protocol Option 8 division. When eCPRI protocol Option 7-2 division and CPRI protocol Option 8 division are mixed, remote units connected by eCPRI and remote units connected by CPRI need to use different mapping and processing of physical resources and logical functions; and because it is a mixed networking, additional mapping relationships need to be added between different protocol processing methods. The prior art does not yet have a mapping method that can support mixed networking of eCPRI protocol Option 7-2 division and CPRI protocol Option 8 division. Summary of the invention

[0113] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0114] In order to realize resource mapping of hybrid networking of eCPRI protocol and CPRI protocol, an embodiment of the present invention provides a resource mapping method, by configuring an extended antenna carrier identifier e-AxCID for an extension unit and a remote unit, different e-AxCIDs correspond to different logical functions, and configuring a first relationship between the e-AxCID and a first interface (such as eCPRI) and / or a second interface (such as CPRI), and utilizing the configured e-AxCID and the first relationship, resource mapping can be performed during data transmission between a host unit and a remote unit, thereby realizing resource mapping during hybrid networking of the eCPRI protocol and the CPRI protocol.

[0115] Specifically, Figure 1 As shown, the resource mapping method described in one embodiment of the present invention is applied to an extension unit, wherein the extension unit is connected to the host unit via a first interface and is connected to the remote unit via a second interface, wherein the resource mapping method includes:

[0116] S110, acquiring an extended antenna carrier identifier e-AxCID configured by a host unit, and a first relationship between the e-AxCID and the first interface and / or the second interface;

[0117] S120, performing resource mapping for data transmission between the host unit and the remote unit according to the plurality of e-AxCIDs and the first relationship;

[0118] Among them, different e-AxCIDs correspond to different logical functions.

[0119] By adopting the resource mapping method described in the embodiment of the present invention, different e-AxCIDs can be configured through the management plane of the host unit. For the extension unit and / or the remote unit, the physical resources of the extension unit and / or the remote unit are divided and managed in advance according to the logical functions, and each physical resource is assigned a corresponding e-AxCID, that is, different e-AxCIDs correspond to different logical functions.

[0120] In one embodiment of the present invention, the resource mapping method can be applied to an extended base station system with a hybrid network of eCPRI protocol and CPRI protocol. In the user plane and the control plane, the extension unit and the host unit are connected through the e-CPRI protocol, and can be optionally divided through Option7-2, that is, the first interface is e-CPRI; the extension unit and the remote unit are connected through the CPRI protocol, and can be optionally divided through Option8, that is, the second interface is CPRI.

[0121] In another embodiment of the present invention, the resource mapping method is applied to an extended base station system of a hybrid network of CPRI protocol to CPRI protocol. In the user plane and the control plane, the host unit and the extended unit are connected via the CPRI protocol, and are optionally divided via Option 8, that is, the first interface is the CPRI protocol; the extended unit and the remote unit are connected via the CPRI protocol, and are optionally divided via Option 8, that is, the second interface is still CPRI.

[0122] The resource mapping method according to the embodiment of the present invention is described in detail below in combination with the above-mentioned implementation modes.

[0123] like Figure 2 As shown, in a base station system of a hybrid network of the eCPRI protocol and the CPRI protocol, the base station system includes: a host unit 1 , an extension unit 2 and a remote unit 3 .

[0124] Among them, for the underlying connection of the base station system:

[0125] The host unit 1 and the extension unit 2 are connected using the Ethernet protocol; the extension units 2 are connected using the Ethernet protocol; and the extension unit 2 and the remote unit 3 are connected using the CPRI protocol.

[0126] For the user plane and control plane connections of extension unit 2:

[0127] Option 7-2 is used between the host unit 1 and the extension unit 2. The upper physical layer is located in the host unit 1, and the lower physical layer is located in the extension unit 2. The e-CPRI protocol is used for connection.

[0128] Extension unit 2 and extension unit 2 are divided by Option 7-2 and connected by e-CPRI protocol;

[0129] The extension unit 2 and the remote unit 3 are divided by Option 8 and connected by the CPRI protocol.

[0130] For the management plane connection of the base station system:

[0131] Adopt NETCONF protocol and model based on YANG language;

[0132] The NETCONF client is deployed in the host unit 1, and the NETCONF server is deployed in the extension unit 2.

[0133] The host unit 1 and the extension unit 2 are connected using the NETCONF management protocol, and the protocol stack is: NETCONF+Secure Shell (SSH) protocol+Transmission Control Protocol (TCP)+IP+Virtual Local Area Network (VLAN)+Ethernet protocol;

[0134] The host unit 1 and the remote unit 3 are connected using the NETCONF management protocol, wherein the protocol stack between the extension unit 2 and the remote unit 3 is: NETCONF+SSH+TCP+IP+VLAN+Ethernet+CPRI.

[0135] In this implementation, for extension unit 2, extension unit 2 divides and manages the physical resources divided by Option 7-2 in advance according to logical functions, that is, the physical resources are divided according to different logical functions to form a physical resource list; wherein each physical resource in the physical resource list can correspond to a logical function; for example, the underlying physical layer baseband processing resources are divided into lower-level receiving endpoint low-level-rx-endpoints resources and lower-level transmitting endpoint low-level-tx-endpoints resources according to the transmitting and receiving directions.

[0136] For remote unit 3, the physical resources divided by Option 8 of remote unit 3 are pre-divided and managed according to logical functions, that is, the physical resources are divided according to different logical functions to form a physical resource list; wherein each physical resource in the physical resource list can correspond to a logical function; for example, data exchange resources are divided into receiving endpoint rx-endpoints resources and tx-endpoints sending endpoint resources according to the sending and receiving directions.

[0137] For the host unit 1, the NETCONF client on the host unit 1 can read the physical resource list on the extension unit 2 and the physical resource list on the remote unit 3 respectively through remote procedure call edit-config (RPC edit-config).

[0138] Further, the NETCONF client on the host unit 1 allocates an e-AxCID for mapping the physical resource allocation and the logical function on the extension unit 2;

[0139] The NETCONF client on the host unit 1 allocates e-AxCIDs that map physical resources and logical functions on the remote unit 3.

[0140] In addition, in an embodiment of the present invention, based on the shared cell information, the NETCONF client on the host unit 1 also configures the relationship between the e-AxCID configuration of the extension unit 2 and the CPRI interface, and configures the relationship between the e-AxCID and the data bearing position of the CPRI interface for the extension unit 2.

[0141] In the embodiment of the present invention, the data bearing position of the CPRI interface includes but is not limited to a relationship that can only include a designated IQ position of a CPRI frame packet.

[0142] Furthermore, the NETCONF client of the host unit 1 also configures the relationship between the e-AxCID and the designated IQ position (ie, the data bearing position) of the CPRI frame packet for the remote unit 3 .

[0143] For the remote unit 3 , the NETCONF client of the host unit 1 also configures the relationship between the e-AxCID and the physical antenna for the remote unit 3 .

[0144] According to the above, in the resource mapping method described in the embodiment of the present invention, in this implementation, for the extension unit 2, the first interface is e-CPRI and the second interface is CPRI. The extension unit 2 obtains multiple e-AxCIDs configured by the NETCONF client of the host unit 1, wherein the configured e-AxCIDs have a one-to-one mapping relationship with the physical resources on the extension unit 2, and different physical resources correspond to different logical functions.

[0145] In addition, the extension unit 2 also obtains a first relationship between the configured e-AxCID and the second interface (ie, CPRI). In this implementation, the first relationship includes:

[0146] a correspondence between the configured e-AxCID and the second interface;

[0147] The relationship between the e-AxCID and the data bearing position of the second interface (such as the designated IQ position of the CPRI data frame packet).

[0148] In the embodiment of the present invention, the e-AxCID configured by the host unit 1 for the extension unit 2 satisfies the following rules:

[0149] Optionally, for the same extension unit, only one e-AxCID is configured for a data stream in the same data transmission direction (uplink or downlink), and the e-AxCIDs of different data streams are different;

[0150] For the same uplink user plane data flow, the lower layer receiving endpoint in the extension unit and the receiving endpoint in the remote unit connected to the extension unit are configured with the same e-AxCID;

[0151] For the same downlink user plane data flow, the lower layer sending endpoint in the extension unit and the sending endpoint in the remote unit connected to the extension unit are configured with the same e-AxCID;

[0152] For the same user plane data flow in the same shared cell, the sending endpoints in different remote units are configured with the same e-AxCID, and the receiving endpoints rx-endpoints in different remote units are configured with the same e-AxCID.

[0153] Optionally, for the same extension unit 2, the e-AxCIDs configured for data flows in different data transmission directions may be the same or different.

[0154] According to the e-AxCID and the first relationship configured by the host unit 1 for the extension unit 2 and the remote unit 3, Figure 2 and Figure 3 , the process of data transmission in the downlink direction may include:

[0155] When the host unit 1 sends data for a certain logical resource (such as a logical cell, a logical carrier or a logical transmission channel, etc.), different e-AxCID identifiers are added to different data streams sent. After receiving the data (downlink transmission data), the extension unit 2 parses the e-AxCID field in the packet header of the data packet, and determines the corresponding physical resource, such as the underlying physical layer baseband processing resource, based on the correspondence between the e-AxCID field and the physical resource; or forwards the data packet to the next-level extension unit for processing;
