The RE AGENT node deploys a vRE node to the RE with the same identifier, and the vREC node establishes a session relationship with the first vRE node, and masks 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, and any of the at least one first vRE node may belong to a third vRE of the RE deployment, and the RE may deploy at least one third vRE. The first vRE node is shown in Figure 3. The vRE000 node to the vRE00n node in the RE AGENT node illustrated in the middle, and the third vRE is the vRE00 node in the RE AGENT node illustrated in FIG.

For example, as shown in FIG. 3, the vRE00 node deployed by the RE AGENT node is the same as the vRE00 node deployed by the RE, and 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 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 can also deploy a vRE10 node, a vRE20 node, 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 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, the RE carrier resources are allocated on demand, and each REC may have its own RE carrier resources; or each REC contends for the RE carrier resources. When a certain REC fails, other candidate RECs may use the contending RE carrier resources.

The vBTS node is used to implement the function of the BTS, and each vBTS node includes one vREC node and a second vRE node. The function of the second vRE node is provided by the RE.

It should be noted that the vBTS node is a virtualized BTS. When the BTS function is required, the NFVI allocates computing resources, storage resources, and transmission resources to establish a vBTS. When the BTS function is not required, the NFVI can release the computing resources allocated for establishing the vBTS. , storage resources and transmission resources, cancel vBTS, therefore, vBTS nodes are more flexible. Thus, the location of the vRE node used by the vBTS node can also be changed, but once the location of the vRE node is determined, the vBTS node records the location of the vRE node so that the vBTS node uses the vRE node, and therefore, the second vRE 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 the 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. Is the main interface between REC and RE by the Industrial Cooperation Organization, the General Public Radio Interface Alliance. specification. The NFVI node communicates with the RE via CPRI.

Access, the vRE node establishes a one-to-one session relationship with the vREC node, and can simultaneously adapt more vREC nodes.

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 an identifier of the vREC node and an identifier of the accessed RE.

It should be noted that, before step 101, the network management system needs to first 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, bandwidth, and the like. The network management system notifies the NFVI node to create an RE, and informs the REs of the RE and carrier resources that each vBTS node can use, 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 identifier of the vREC node and the identifier of the accessed access RE, and generates a vRE node.

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

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

The wireless device agent integrates the access of each virtual base station transceiver station to the wireless device, for example, uniformly converts the carrier number, converts it into a unified 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 the RE with the same identifier, and the vREC node establishes a session relationship with the vRE node, and masks multiple vREC instances for the RE, so that the RE considers that there is only one vREC instance.

Step 106: The wireless device receives an 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 a response message sent by the wireless device.

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

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 active report message may be: the fault information of the RE and other behavior information of the RE itself. For example, RE itself manages its own faults, which has nothing to do with REC. When the RE finds itself faulty, it can report to the REC proactively, so that the REC can handle 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 proxy 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 station transceiver station node, and the wireless device proxy storage service is related. The service-related active report message is mainly the available state of the RE resource, such as the antenna channel. Available status. If the active reporting message is unrelated to the service, the wireless device proxy processes the active reporting message itself.

For example, the wireless device agent determines the active reporting message, if the active reporting message is For messages unrelated to resource allocation, the wireless device agent sends an active report message to all virtual base transceiver stations. If the active reporting message is a message related to resource allocation, the wireless device proxy sends an active reporting message to the associated virtual base transceiver station.

It should be noted that, since the virtual base transceiver station node and the base transceiver station are different, the virtual base transceiver station focuses on the carrier service, and other, such as the upgrade of the wireless device, the virtual base transceiver station does not care, and can be used by the wireless device. The agent can complete the wireless device agent and 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 fault response message, and the wireless device agent records the fault information so that the gateway can directly query.
