Optical fiber or cable connection is used between REC and RE. The REC is provided with multiple optical ports or electrical ports, and one optical port or electrical port can cascade multiple REs.

In the era of single-mode base stations, a REC only supports one network standard, such as Global System for Mobile Communication (English full name: Global System for Mobile communication, English abbreviation: GSM) or Universal Mobile Telecommunications System (English full name: Universal Mobile Telecommunications System, English full name: Global System for Mobile communication, English abbreviation: GSM) Abbreviation: UMTS), at this time, one REC can manage multiple REs, and one RE is only subordinate to one REC.

However, when establishing a one-to-one session relationship between vREC nodes and REs, since vREC nodes are virtualized, the number of REs can be any number, while REs are physical devices that provide RE functions for each vREC node. Due to limited capability resources, the RE may not be able to adapt to more vREC nodes at the same time, and support more vREC nodes to establish a one-to-one session relationship.

Embodiment 3

An embodiment of the present invention provides a schematic diagram of a C-RAN system, as shown in FIG. 3 , including:

The NFVI node is the underlying support structure, including computing resources, storage resources, and transmission resources. It is used for deploying at least one virtual base transceiver station (English full name: Virtual Base Transceiver Station, English abbreviation: vBTS) node in the C-RAN system. Computing resources, storage resources, and transmission resources. The NFVI node includes a wireless device proxy REAGENT node.

The RE AGENT node is used to deploy the first vRE node according to the number of vREC nodes, and establish a one-to-one session relationship between the first vRE node and the vREC node, that is, to realize the simultaneous adaptation of the RE to multiple vBTSs and avoid resource conflicts. RE AGENT nodes can be deployed in NFVI nodes through the network management system. The RE AGENT node deploys a vRE node to REs with the same identifier, the vREC node establishes a session relationship with the first vRE node, and shields multiple vREC instances for the RE, so that the RE considers that there is only one vREC instance. That is, the RE AGENT node further includes at least one third RE, any first vRE node in the at least one first vRE node may belong to a third vRE deployed by the RE, and the RE may deploy at least one third vRE. The first vRE nodes are nodes from vRE000 to vRE00n in the RE AGENT nodes illustrated in FIG. 3 , and the third vRE is the vRE00 node in the RE AGENT nodes illustrated in FIG. 3 .

For example, as shown in Figure 3, the vRE00 node deployed by the RE AGENT node is the same as the vRE00 node deployed by the RE. The vRE000 node to the vRE00n node belong to the vRE00 node deployed by the RE AGENT node, and the vRE000 node to the vRE00n node all access RE0, RE0 The vRE00 node provides resources for the vRE000 node to the vRE00n node.

It should be noted that, the RE in FIG. 3 may also deploy vRE10 nodes, vRE20 nodes, and the like. Correspondingly, the RE AGENT node deploys the same vRE10 node as the vRE10 node deployed by the RE. At the same time, the vRE100 node to the vRE10n node belong to the vRE10 node deployed by the RE AGENT node, and so on.

The RE AGENT node is also used to convert the RE interface between the vBTS node and the NFVI node into a CPRI interface.

The RE AGENT node is further configured to convert the CPRI interface between the RE and the NFVI node into an RE interface.

The RE AGENT node is also used for many-to-one mapping between vREs and REs used by the vBTS, realizing the function of the RE for the vREC node, realizing the function of the vREC node for the RE, and realizing the uplink and downlink conversion.

Specifically, refer to the CPRI protocol to realize the function of REC and the function of RE, including at least one of the following functions:

Communication function, CPRI protocol supports between REC and RE through Transmission Control Protocol/Internet Protocol (English full name: Transmission Control Protocol/Internet Protocol, English abbreviation: TCP/IP) or Advanced Data Link Control (English full name: High-Level Data Link Control, English abbreviation: HDLC) mode communication.

Device management function, service-independent device management function between REC and RE, including reset, electronic label, RE panel lighting, CPRI port enable, CPRI rate setting, temperature query, power consumption query, standing wave test, etc.

Upgrade management function, REC performs version control on RE, including version query, version loading, version activation, patch download and patch activation, etc.

Carrier management function, REC adds, deletes and modifies the carriers on the RE.

Delay management function, the REC queries the carrier delay and CPRI forwarding delay on the RE, and configures delay compensation to the RE.

Peripheral management function, REC can also manage other external devices attached to RE, such as ESC antenna, uplink low noise amplifier, dry node and fan and other devices.

With the fault management function, the RE monitors its own faults and synchronizes fault information to the REC.

The RE AGENT node is also used to implement the management interface function, and can configure the functions and resources of the RE AGENT node.

For example, configure the resources used by the vRE. For example, RE carrier resources are allocated on demand, and each REC may have its own RE carrier resources; or each REC competes for RE carrier resources, and when a REC fails, other candidate RECs can use the competing RE carrier resources.

The vBTS node is used to implement the function of the BTS, and each vBTS node includes a vREC node and a second vRE node. The functionality of the second vRE node is provided by the RE. A BTS can be thought of as a base station. The second vRE nodes are the vRE000 nodes to the vRE00n nodes among the vBTS nodes illustrated in FIG. 3 .

It should be noted that the vBTS node is a virtualized BTS. When the functions of the BTS are required, NFVI allocates computing resources, storage resources, and transmission resources to establish the vBTS. When the functions of the BTS are not required, the NFVI can release the computing resources allocated for the establishment of the vBTS. , storage resources and transmission resources, cancel the vBTS, therefore, the vBTS node is more flexible. Therefore, the position of the vRE node used by the vBTS node can also be changed. However, once the position of the vRE node is determined, the vBTS node records the position of the vRE node, so that the vBTS node can use the vRE node. Therefore, the second vRE node included in the vBTS node The node is equivalent to an index of the first vRE, and the first vRE node included in the RE AGENT node provides the function of RE.

The vBTS node communicates with the NFVI node through the RE interface. The general CPRI defines the interface relationship between the REC of the base station and the RE of the base station. It is an industry cooperative organization, the Common Public Radio Interface Alliance, that formulates the main interface specification between REC and RE. NFVI nodes communicate with REs through CPRI.

C-RAN and RE are physical devices, and NFVI nodes and vBTS nodes are virtual nodes deployed on C-RAN.

In this way, by deploying the RE AGENT node in the NFVI node in the C-RAN system, the RE AGENT node can deploy a virtual radio equipment (vRE) node, thereby virtualizing multiple RE AGENT nodes for the same RE without modifying the RE. vRE node, the multiple vRE nodes independently access the same RE, the vRE node establishes a one-to-one session relationship with the vREC node, and can adapt to more vREC nodes at the same time.

The REC, RE and RE AGENT devices are each an entity device. The RE AGENT device is deployed between the REC entity device and the RE entity device, and a one-to-one session relationship between the REC and the RE is established. RE AGENT equipment can be managed by any predetermined BTS.

The REC is equivalent to the baseband subsystem, the RE is equivalent to the MF subsystem, the REC implements the function of the baseband subsystem, and the RE implements the function of the MF subsystem. For the function of the baseband subsystem and the function of the IF subsystem, reference may be made to the description of Embodiment 2, and details are not described herein again in this embodiment of the present invention.

For the function of the RE AGENT device, reference may be made to the description of the RE AGENT node in Embodiment 3, and details are not described herein again in this embodiment of the present invention.

By setting a wireless proxy RE AGENT device in the base station, the RE AGENT device deploys a virtual vRE node, so that multiple vRE nodes are virtualized for the same RE without modifying the RE, and the multiple vRE nodes perform independent operations on the same RE. Access, the vRE node establishes a one-to-one session relationship with the vREC node, which can adapt to more vREC nodes at the same time.

Embodiment 5

An embodiment of the present invention provides a data processing method based on a C-RAN system, as shown in FIG. 5 , including:

Step 101: The virtual wireless device control node sends an access request to the wireless device proxy node.

The access request includes the identity of the vREC node and the identity of the accessed RE.

It should be noted that, before step 101, the network management system needs to create a vBTS node and configure RE resources that can be used by the vBTS node, such as the location of the RE, the available carrier, and the bandwidth. The network management system informs the NFVI node to create the RE, and informs the RE of the RE and carrier resources that can be used by each vBTS node, and the vBTS node includes the vREC node.

Step 102: The wireless device proxy node receives the access request.

Step 103 , the wireless device proxy node records the identification of the vREC node and the identification of the visited RE, and generates a vRE node.

The vRE node is the virtual node of the visited RE.

Step 104: The wireless device proxy node converts the RE interface into a common public radio interface CPRI interface.

The wireless device agent integrates the access of each virtual base transceiver station to the wireless device, for example, uniformly converts the carrier number into a uniform CPRI interface mode, and sends the access message to the RE.

Step 105: The wireless device proxy node sends an access request to the wireless device.

The RE AGENT node deploys a vRE node to REs with the same identifier, the vREC node establishes a session relationship with the vRE node, and shields multiple vREC instances for the RE, so that the RE thinks that there is only one vREC instance.

Step 106: The wireless device receives the access request sent by the wireless device proxy node.

Step 107: The wireless device sends a response message to the wireless device proxy node.

Step 108: The wireless device proxy node receives the response message sent by the wireless device.

Step 109: The wireless device proxy node converts the CPRI into the RE interface.

A response message to a request message sent by a wireless device node. After the wireless device proxy node receives the response message, usually the wireless device proxy node sends the response message according to the sender of the request message. The sender can be a virtual base transceiver station node or a wireless device proxy node.

The wireless device proxy node generates a corresponding response message for each virtual base transceiver station node according to the response message result and the resource allocation situation.

Step 110: The wireless device proxy node sends a response message to the corresponding vBTS node.

The response message includes a session identifier of a session relationship between the vREC node and the vRE node.

In this way, based on the C-RAN system, a vRE node is established through the RE AGENT node, and multiple vRE nodes are virtualized for the same RE without modifying the RE, and the multiple vRE nodes access the same RE independently. The vRE node establishes a one-to-one session relationship with the vREC node, and can adapt to more vREC nodes at the same time.

Embodiment 6

An embodiment of the present invention provides a data processing method based on a C-RAN system, as shown in FIG. 6 , including:

Step 201: The wireless device sends an active report message to the wireless device proxy node.

The actively reported message may be: fault information of the RE and other behavior information of the RE itself. For example, the RE itself manages its own faults, which has nothing to do with the REC. When the RE finds itself faulty, it can proactively report to the REC, so that the REC can deal with it immediately and save the loss.

Step 202: The wireless device proxy node receives the active report message sent by the wireless device.

Step 203, the wireless device agent processes the active report message.

If the active report message is related to the service, the active report message is forwarded to the relevant virtual base transceiver station node, and the wireless device agent stores the service-related information. The active report message related to the service is mainly the availability of RE resources, such as antenna channel available status. If the actively reported message has nothing to do with the service, the wireless device agent processes the actively reported message by itself.

For example, the wireless device agent determines the active report message, and if the active report message is a message unrelated to resource allocation, the wireless device agent sends the active report message to all virtual base transceiver station nodes. If the unsolicited report message is a message related to resource allocation, the wireless device agent sends the unsolicited report message to the relevant virtual base transceiver station.

It should be noted that, due to the difference between the virtual base transceiver station node and the base transceiver station, the virtual base transceiver station focuses on the carrier service, and other, such as the upgrade of wireless equipment, the virtual base transceiver station does not care, and can be operated by the wireless equipment. The agent is done, and the wireless device agent can also directly access the wireless device. The wireless device agent receives the upgrade response message, and the wireless device agent continues to load the remaining installation packages. The wireless device agent receives the failure response message, and the wireless device agent records the failure information so that the gateway can directly query.
