The word "if" as used herein may be interpreted as "at … …" or "at … …" or "in response to a determination" depending on the context.

First, terms related to one or more embodiments of the present specification will be explained.

HO/Handover: and (5) switching.

In the prior art, however, in the process of realizing data transmission between a terminal and the internet, a plurality of base stations in the same area need to perform data transmission by a unique core network in the area; and the core network controls the execution of the switching flow in the process of switching the terminal from one base station (base station A) to another base station (base station B); based on the knowledge, the core network has the capability of the control plane and the user plane at the same time, so that the control plane and the user plane have stronger coupling; the strong coupling brings a certain drawback, for example, the software and hardware implementing the control plane and user plane capabilities in the core network must be the same manufacturer. Or the core network must use the same one of the software and hardware to implement the control plane and user plane capabilities. Therefore, the core network cannot flexibly select different software and hardware devices to realize the control plane capability and the user plane capability according to actual requirements.

In addition, in the process of implementing data transmission between the terminal and the internet, multiple base stations in a region (such as province, same-enterprise private network, etc.), it is necessary to send terminal data to a unique core network in the region (such as province, same-enterprise private network, etc.), and forward the terminal data to the internet by the core network, so that the data transmission amount of the core network is huge, resulting in low data transmission efficiency of the core network.

In view of the above, in implementing the decoupling of the control plane network element and the user plane network element, one way is: the communication network realizes the decoupling of the control plane and the user plane through the split design of the network elements, but the mode adopts special protocols and flows to realize corresponding functions. Although some internet technologies such as service, HTTP (hypertext transfer protocol), virtualization and the like are adopted to carry out internal transformation, the communication network and the affiliated IT network are not integrated as a proprietary system, and especially, the communication network and the affiliated IT network are faced to a base station switching scene specific to a mobile network and are realized by the linkage of a control plane and a user plane, which is a challenge for the integration of the communication network and the IT network equipment.

Therefore, how to implement decoupling of the control plane network element and the user plane network element in a base station Handover scenario specific to the mobile network becomes a problem to be solved, based on which, the present disclosure provides an Xn Handover scheme with a first scheme being the 3GPP standard, see fig. 1, and fig. 1 is a schematic diagram of an Xn Handover procedure provided in an embodiment of the present disclosure. In the scheme, the control plane performs preparation work of switching through 0-7 steps in fig. 1, and after the preparation work is finished, a new user plane channel is established through 8-10 steps, and finally the switching is finished. It should be noted that, the scheme includes a user terminal (UE: user Equiment) Source base station (Source gNB) Target base station (Target gNB), an access and mobility management network element (AMF), and a user plane management network element (UPF), based on which the specific steps include:

before the step is executed, the source base station sends an Xn interface establishment request to the target base station (XnAPXnSetupRequest), and the target base station needs to return an Xn interface establishment request response to the source base station (XnAP XnSetupResponse), thereby completing the interface establishment between the two.

Step 1: the user terminal sends a measurement report to the source base station (Measurement Report).

Step 2: the source base station sends a handover request to the target base station based on the measurement report (XnAP HandoverRequest)

Step 3: the target base station transmits a handover request acknowledgement (XnAP HandoverRequestAcknowledge) to the source base station based on the handover request.

Step 4: the source base station initiates an RRC reconfiguration to the user terminal (RRC Reconfiguration).

Wherein the RRC refers to a radio resource control layer (Radio Resource Control).

Step 5: the source base station performs SN status migration (5 XnAP SNStatus Transfe).

Step 6: a Target random access (RACH on Target) is performed between the user terminal and the Target base station.

Step 7: the user terminal transmits the RRC reconfiguration complete to the target base station (RRCReconfigurationComplete).

Step 8: the target base station sends a path switch request to the AMF (NGAP PathSwitchRequest).

Step 9: the AMF sends a path switch request acknowledgement to the target base station (NGAPPathSwitchRequestAcknowledge).

Step 10: the target base station sends a UE context release to the source base station (XnAPUEcontext Release).

Based on the signaling interaction in the steps, the base station switching work is realized, but the whole flow is limited to the communication network element interaction, and has no relation with the affiliated IT network, and the IT network only provides the connectivity of the signaling interaction. In addition, the protocol flows are all proprietary protocols, and the bottom network is not aware and does not participate.

The second solution provided in the present disclosure is an implementation manner of the Proxy Mobile IPv6 solution in the LTE network, referring to fig. 2, and fig. 2 is a schematic diagram of a network handover procedure provided in an embodiment of the present disclosure; and the present disclosure provides another Proxy Mobile IPv6 scheme design with a standard scheme, referring to fig. 3, and fig. 3 is a schematic diagram of another network handover procedure provided in an embodiment of the present disclosure. Wherein, proxyMobileIPv in fig. 2 and 3, PMIPv6 is proxy mobile IPv6 protocol; eNB (evolvedNode B) is an evolved node b; MME (Mobility MANAGEMENT ENTITY) is a Mobility management entity; SGW (Served Gateway) is a service gateway; PGW (Packeted DataNetwork Gateway) is a packet data network gateway serving gateway; UE (User Equiment) is a user terminal; LMA (LocalMobilityAnchor) local mobility anchor points; MAG (MobileAccessGateway) is a mobile access gateway; GTP-U Tunnel (GPRS Tunneling Protocol for User Plane) is a GPRS Tunnel at the user plane. PMIPv6 (ProxyMobileIPv 6) is proxy mobile IPv6 protocol; LMA (LocalMobilityAnchor) is a local mobility anchor; MAG (MobileAccessGateway) is a mobile access gateway; the IP Tunnel is an IP Tunnel; home Network is the Home Network; LMAA (LMAAddress) is the local mobile anchor address; MN (MobilityNode) is a mobile node; the MN-HoA (MN' HomeAddress) is the home address of the mobile node; MN-HNP (MN's Home Network Prefix) is the prefix of the home address of the mobile node, and Proxy-CoA (Proxy Care ofAddress) is the Proxy care-of address; PBU (ProxyBindingUpdate) is a proxy binding update message; PBA (Proxy BindingAcknowledgement) is a proxy binding acknowledgement message.

Based on fig. 2 and 3, two corresponding schemes are hierarchical design of MAGs and LMAs, and IP tunel and coas are used to realize that the movement between MAGs keeps the address unchanged. The use in the communication network is to locate the SGW network element to the MAG, the PGW to the LMA, and the UE to move between different MAGs, but PMIPv6 is more used for handover across systems, and is also a standard 3GPP solution in the system. It is necessary to add mobility header support in the IPv6 header.

Based on the above, the data processing method based on the wireless network solves the problem of linkage between the control plane and the user plane in the switching scene by using the general routing protocol of the IT network. On the one hand, the method can realize the expandable private network based on the original network rapidly and at low cost, and on the other hand, the base station is transformed into a distributed computing node to be integrated into the IT network as required.

Compared with other schemes, the communication function is transferred to IT equipment (such as a switch and the like) as far as possible, better compatibility and flexibility are provided by utilizing the function of the IT equipment, and meanwhile, the switching in a system can be supported, the switching between systems can be supported, the application scene is enlarged, and a foundation is provided for further expansion.

In particular, in the present specification, a data processing method based on a wireless network is provided, and the present specification relates to a data processing system based on a wireless network, a computing device, a computer readable storage medium, and a computer program, which are described in detail in the following embodiments one by one.

Fig. 4 is a schematic diagram of a data processing system based on a wireless network according to an embodiment of the present disclosure. Referring to fig. 4, the system includes a base station a, a base station B, a proxy module C, a proxy module D, a switch E, a switch F, a terminal, and a data network. The block diagram of the data processing system based on the wireless network shown in fig. 4 is added with modules such as the proxy module C and the proxy module D, compared with the existing mobile network networking. In the case where the wireless network-based data processing system is applied to a mobile communication scenario, the proxy module C and the proxy module D may be used as a dividing line of a mobile communication (3 GPP communication) domain and a data communication domain. In addition, in the case that the data processing system based on the wireless network is applied to the WiFi wireless network scene, the proxy module C is used, and the proxy module D can be used as a parting line of the WiFi wireless network and the data communication domain. That is, a proxy module in a wireless network-based data processing system, which can be applied to a mobile communication domain and a data communication domain, supports applications of different scenarios; the mobile communication domain can be expanded into a WiFi wireless network scene, or can be a combination of a plurality of different 3GPP communication domains; this is not particularly limited in this specification.

In addition, in the wireless network-based data processing system provided in the present disclosure, the deployed position of the proxy module may be set according to the needs of the actual application scenario, which is not specifically limited in the present disclosure. For example, the proxy module C and the proxy module D may appear as a single network element, i.e. the proxy module may exist as a single piece of hardware, independent of the base station and the switch; and various interoperations between the base station and the switch are implemented. Meanwhile, the function of the proxy module can be integrated into the switch or the base station, that is, the proxy module can be integrated into the base station or the switch, and can be used as a part of the base station or the switch to realize various interaction operations between the base station and the switch.

In practical application, the proxy module and the base station may be in a one-to-one correspondence relationship, or in a one-to-many relationship, and fig. 4 is only an example, where the correspondence relationship between the proxy module and the base station is set to be a one-to-one correspondence relationship.

Note that, the data communication domain in fig. 4 may use a general protocol and flow, and may not include a protocol or flow dedicated to 3GPP such as GTP, SCTP, and the like.

Based on the above, the data processing system based on wireless network can achieve the purpose of supporting wireless network switching by using a routing protocol, so that the problem of linkage between a control plane and a user plane in a base station switching scene is solved by using a routing protocol common to an IT network (data communication domain), and the specific implementation steps are shown in fig. 5, and fig. 5 is a schematic diagram of a processing procedure of the data processing system based on wireless network provided in one embodiment of the present specification, and specifically includes the following steps.

Step 502: the terminal performs normal data communication with the data network under the base station a.

Step 504: when the terminal moves from the area covered by the base station a to the area covered by the base station B, a handover procedure for the base station a and the base station B is triggered.

The switching process may be configured for the base station according to an actual application scenario, which is not specifically limited in this specification, for example, the switching process configured for the base station may be an Xn switching process, an X2 switching process, or the like.

Taking the handover procedure as an Xn handover procedure as an example, all procedures in the Xn handover procedure conform to the 3GPP standard, wherein part of procedures are completed in the base station, and part of procedures are completed in the proxy module C or the proxy module D. It should be noted that, in the data processing system based on the wireless network provided in the present disclosure, it may be determined, according to the needs of the actual application scenario, which steps in the Xn switching flow are completed at the base station, and which flows are completed at the proxy module; this is not particularly limited in this specification. Only after the switching process is executed, the terminal can be switched from the base station A to the base station B.

Step 506: the base station A and the base station B perform signaling interaction based on the switching flow, and the base station A can buffer user plane data which needs to be sent to the terminal in the process of executing the switching flow in the base station A or the proxy module C.

It should be noted that the route to the terminal at this time is still through the switch E.

Specifically, in the process of performing the Xn handover procedure by the base station a and the base station B, signaling interaction is necessary. The signaling interaction can be realized through the forwarding of the proxy module C or the proxy module D. For example, when the base station a needs to send a handover decision request to the base station B, the base station a may send the request to the proxy module C corresponding to the base station a, where the proxy module C sends the request to the proxy module D, and then sends the request to the base station B through the proxy module D. Or the base station a may send the request directly to the base station B via a data transmission channel with the base station B. Based on this, it is known that the signaling interaction between the base station a and the base station B can be implemented in various ways, and this description is not limited in particular.

In addition, during the process of executing the handover procedure, the base station a and the base station B buffer the user plane data (e.g., multimedia data, text data, etc.) that needs to be sent to the terminal in the base station a or the proxy module C.

Step 508: under the condition that the switching flow is successfully finished, the proxy module C can send dynamic route update to the switch E to withdraw the route of the original terminal.

Specifically, the proxy module C can sense the execution condition of the Xn switching flow, and under the condition that it is determined that the switching flow is successfully ended, the proxy module C can send out dynamic route update to the switch E, so as to inform the switch to withdraw the route of the original terminal (the terminal connected under the base station a).

Step 510: and under the condition that the switching flow is successfully ended, the proxy module D sends dynamic route update to the switch F to announce the route of the terminal.

Specifically, the proxy module D can also sense the execution condition of the Xn switching flow, and in the case of determining that the switching flow is successfully ended, the proxy module D can send out a dynamic route update to the switch F to inform the switch of announcing the route of the terminal (the terminal connected under the base station B).

Step 512: and after the route is converged, the terminal is communicated with the data network.

Specifically, after the route converges, the terminal can communicate with the data network through the base station B, the proxy module D and the switch F, so as to realize data communication between the terminal and the data network.

In the process of data communication between the terminal and the data network, the terminal can send the user plane data to the base station B, the base station B needs to send the user plane data to the proxy module D in the form of a data packet of the 3GPP communication protocol, and then the proxy module D sends the user plane data to the switch F, where the user plane data can be directly forwarded to the data network through the switch F, where the data network can be understood as a network capable of transmitting the user plane data to a corresponding data processing object, and the data network includes a network capable of processing the data processing object of the user plane data; such as a data communication network, an enterprise private network, etc.; the data processing object may be understood as an object capable of processing the user plane data, for example, a server, a database, a hardware device (such as a computer, a server) in an enterprise private network for processing the user plane data sent by the terminal, and so on. For example, in a live broadcast scenario, the user plane data may be understood as live broadcast data, the terminal may be a mobile phone, and the data processing object is a live broadcast server, based on this, the mobile phone may communicate with the data network in the process of live broadcast in the foregoing steps 502 to 518, and send the live broadcast data generated in the live broadcast process to the live broadcast server in the data network. Or the mobile phone can be understood as forwarding the live broadcast data generated in the live broadcast process to the live broadcast server through the data network, so that the live broadcast server processes the live broadcast data.

For example, in an autopilot scenario, the terminal may be an autopilot, and the user plane data may be understood as data sent by the autopilot (such as an image of a surrounding environment of the autopilot, coordinate information of the autopilot, etc.), and the data processing object is a server for managing the autopilot.

In addition, in the process of forwarding data, the type of the data packet (i.e. user plane data) of the 3GPP communication protocol cannot be identified by the switch, so that the problem that the user plane data cannot be sent is caused. Therefore, the proxy module D can also play a role in protocol conversion in the data transmission process, so as to convert user plane data (such as data packets or data packets) generated based on the 3GPP communication protocol into data packets or data packets corresponding to the specific routing protocol; the exchange can identify and forward the data message or data packet corresponding to the routing protocol, so that the normal data transmission between the terminal and the data network is realized.

The protocol conversion process may be:

The agent module extracts data (such as pictures, characters and the like) which are required to be sent by a user from user plane data (data messages) generated by a 3GPP communication protocol; and repackaging the data based on the routing protocol, thereby obtaining the data message which corresponds to the routing protocol and can be forwarded to the data network through the switch.

It should be noted that, the specific routing protocol may prioritize the generic routing protocols such as BGP and OSPF, and in the case that the switch is controllable, a custom routing protocol may also be used. This is not particularly limited in this specification. The switch is controllable, which is understood as being capable of carrying out custom configuration on software and hardware of the switch.

Moreover, the data transmission mode avoids the problem of low data transmission efficiency of the core network due to huge data transmission quantity of the core network. In practical applications, a core network may exist in a certain area (for example, a private network of an a enterprise), but the core network needs to be responsible for the connection between all base stations in the private network of the a enterprise and the data network, that is, all base stations in the private network of the a enterprise need to send data to the core network and forward the data to the data network by the core network.

Therefore, in consideration of the problem, the data processing system based on the wireless network provided by the specification transfers the data forwarding function (user plane capability) of the original core network to the switch implementation by adding the proxy module, so that the decoupling of the user plane and the control plane is realized. For example, a base station deployed by a private network of an enterprise a does not need to send data to a core network when in data communication with a data network; but directly forwards the data to the data network through the switch closest to the base station.

The problem of linkage between the control plane and the user plane in the switching scene is solved by the universal routing protocol of the IT network in the data processing system based on the wireless network. On the one hand, the method can realize the expandable private network based on the original network rapidly and at low cost, and on the other hand, the base station is transformed into a distributed computing node to be integrated into the IT network as required.

Fig. 6 shows a flowchart of a data processing method based on a wireless network, which is applied to a data processing system, and the system includes a base station, a data processing module and a data forwarding module, and the method specifically includes the following steps.

Step 602: the base station receives initial data sent by the terminal and sends the initial data to the data processing module.

The data processing module may be understood as a module capable of processing initial data to obtain target data, for example, a proxy module in the above-mentioned data processing system based on a wireless network. A data forwarding module may be understood as a module that is capable of implementing a data forwarding function. Such as the switches in the wireless network-based data processing system described above.

The initial data may be understood as data generated based on a protocol used in a wireless network environment; the initial data may be, for example, a data packet generated by a 3GPP specific protocol or procedure, or a data packet. I.e. user plane data. Such 3GPP specific protocols include, but are not limited to, GTP protocol, SCTP protocol, etc. Meanwhile, in the case that the data processing method based on the wireless network is applied to different scenes, the initial data are also different; for example, in an autopilot scenario, the terminal may understand that the autopilot car, and the initial data may understand that the autopilot car transmits to the base station environmental image data of the current surroundings of the car. The environmental image data may be sent to the base station in the form of a data packet or a data message.

For another example, in a live broadcast scenario, the initial data may be understood as live broadcast data, and the terminal may be a mobile phone, where the live broadcast data may also be sent to the base station in a data packet or a data packet.

The terminal may be a mobile terminal in a mobile communication scenario, including but not limited to a mobile phone, a notebook computer, a smart bracelet, a tablet computer, an autopilot car, etc.

Specifically, the base station can be connected with a terminal, and when the terminal needs to send data to the data network, the terminal can generate initial data based on a special protocol in the wireless network and send the initial data to the base station; the base station, after receiving the initial data, can forward the initial data to a data processing module.

The following further describes the initial data transmission from the base station to the data processing module by taking the application of the data processing method based on the wireless network in the mobile communication scenario as an example. The terminal is a mobile phone, the data processing module is an agent module, and the data forwarding module is a switch. The initial data is a data message.

Based on this, in the mobile communication scenario, the mobile phone is connected with different base stations, and when the mobile phone needs to perform text transmission with the data communication network and other terminals (such as other mobile phones, servers, etc.), it is necessary to package text data into a data packet by using a protocol dedicated to 3GPP, and send the data packet to the base station. And the base station forwards the data message to a proxy module corresponding to the base station under the condition that the base station receives the data message.

In addition, the wireless network-based data processing method provided in the present specification can also be applied to an autopilot scenario, wherein in the autopilot scenario, the terminal may be an autopilot car, and the initial data may be understood as environmental image data of the surrounding environment of the autopilot car sent to a base station by the autopilot car; based on the above, the automatic driving automobile can collect the environmental image data of the surrounding environment in real time in the running process and send the environmental image data to the base station. The base station, after receiving the ambient image data, can send the ambient image data to the proxy module.

Step 604: the data processing module is used for receiving the initial data sent by the base station, determining attribute information of the initial data and determining a corresponding data network transmission protocol for the initial data according to the attribute information; and

And converting the initial data into target data based on the data network transmission protocol, and sending the target data to the data forwarding module.

The attribute information of the initial data includes, but is not limited to, a protocol identifier corresponding to the initial data, base station identifier information corresponding to the initial data, and the like, where the attribute information is used as the protocol identifier corresponding to the initial data, and the protocol identifier is used to uniquely identify a protocol that generates the initial data. For example, the initial data is a data message generated based on a GTP protocol; the attribute information of the initial data is the identifier of the GTP protocol, where the identifier may be a number, an ID, a name, etc.

The data network transport protocol may be understood as a routing protocol including, but not limited to, BGP, OSPF, etc. generic routing protocols.

The target data can be understood as a data message which is generated based on the repackaging of the routing protocol, and the data message can be forwarded by a switch and a router.

Specifically, after receiving initial data sent by a base station, the data processing module can determine attribute information of the initial data, determine a corresponding data network transmission protocol for the initial data based on the attribute information, provide the data network transmission protocol to convert the initial data into target data, and send the target data to the data forwarding module.

Along with the above example, the target data is a data packet generated based on BGP routing protocol. Based on this, when the proxy module receives the data packet sent by the base station, in order to ensure that the data packet can be forwarded by the switch, a protocol identifier (such as an identifier of a GTP protocol) corresponding to the data packet needs to be determined.

A corresponding routing protocol (e.g., BGP) is determined for the data packet based on the protocol identification, the routing protocol capable of converting the data packet into a data packet forwarded by the switch. And then, the proxy module can convert the data message transmitted under the mobile communication network into the data message forwarded in the IT network based on the routing protocol. In the process of generating the data message forwarded in the IT network based on the routing protocol, the method may be: and packaging the data message transmitted under the mobile communication network based on the routing protocol to obtain the data message forwarded in the IT network. Or the proxy module extracts text data to be transmitted by the user from the data message transmitted by the mobile communication network, and encapsulates the text data based on the routing protocol to obtain the data message forwarded in the IT network. After the agent module obtains the data message which can be forwarded in the IT network, the data message is sent to the switch.

In addition, in the case that the wireless network-based data processing method provided in the present specification is applied to an autopilot scenario, after the base station forwards the environmental image data sent by the autopilot to the proxy module, since the current environmental data is a data packet generated based on the 3GPP communication protocol, the data packet cannot be forwarded by an interaction machine, a router, and other devices in the data communication network.

Therefore, the proxy module needs to convert the data packet through a routing protocol to obtain a data packet capable of being transmitted in the data network. Specifically, the proxy module can determine a protocol identifier corresponding to the data packet, determine a corresponding routing protocol for the data packet based on the protocol identifier, and convert the data packet transmitted under the mobile communication network into a data packet forwarded in the IT network based on the routing protocol. The process of generating the data packet forwarded in the IT network based on the routing protocol may be: and packaging the data packet transmitted under the mobile communication network based on the routing protocol to obtain the data packet forwarded in the IT network. Or the agent module extracts the environment image data of the automatic driving automobile from the data packet transmitted under the mobile communication network, and encapsulates the environment image data based on the routing protocol to obtain the data packet forwarded in the IT network. And sends the data packet to the switch.

In the embodiment provided in the present disclosure, the correspondence between the protocol dedicated to 3GPP and the routing protocol is recorded in the proxy module, that is, when the proxy module receives a data packet generated by the protocol dedicated to 3GPP, the proxy module can determine the routing protocol for converting the data packet based on the protocol identifier corresponding to the data packet, and generate the corresponding data packet based on the routing protocol, so that the data sent by the base station is forwarded to the data network through the switch.

The determining the attribute information of the initial data, and determining the corresponding data network transmission protocol for the initial data according to the attribute information, includes:

The data processing module determines a protocol identifier of the initial data, wherein the protocol identifier is an identifier corresponding to a transmission protocol for generating the initial data;

Determining a preset corresponding relation between the protocol identification and a data network transmission protocol, and determining a corresponding data network transmission protocol for the protocol identification according to the preset corresponding relation;

and determining the data network transmission protocol corresponding to the protocol identifier as the initial data.

Specifically, the data processing module can determine a protocol identifier corresponding to initial data sent by the base station when the initial data is received, and determine a corresponding relationship between a pre-established protocol identifier and a data network transmission protocol, for example, an identifier of a GTP protocol corresponds to a BGP protocol, and an identifier of an SCTP protocol corresponds to an OSPF protocol.

Based on the data network transmission protocol corresponding to the protocol identification is determined according to the preset corresponding relation, and the data network transmission protocol is used as initial data to determine the corresponding data network transmission protocol.

In the embodiment provided in the present specification, the proxy module needs to acquire the text data to be encapsulated from the data packet, so that the text data can be conveniently encapsulated into the data packet which can be forwarded by the switch, and the specific implementation manner is as follows.

The converting the initial data into target data based on the data network transmission protocol comprises:

The data processing module acquires data to be converted from the initial data;

and packaging the data to be converted into target data based on the data network transmission protocol.

The data to be converted may be understood as data that is carried in the initial data and needs to be encapsulated again, for example, text data, multimedia data, environmental image information of the current position of the automatic driving automobile, live broadcast data, and the like.

The mode of acquiring the data to be converted from the initial data can be set according to the actual application scene. For example, all data included in the initial data may be identified one by one, so as to obtain data to be converted in the initial data; or the proxy module can determine the position information of the module to be converted in the initial data, and directly acquire the data to be converted based on the position information.

Along the above example, the data to be converted is text data carried in the data message; based on the above, the proxy module can extract text data to be sent by the user from the data message, and re-package the text data through the routing protocol to obtain the data message which can be forwarded by the switch.

In practical application, in order to improve the acquisition efficiency of the data to be converted and ensure the accuracy of the data to be converted; the proxy module can accurately extract the data to be converted from the data message based on the position information of the data to be converted, and the specific implementation mode is as follows.

The data processing module acquires data to be converted from the initial data, and the data processing module comprises:

the data processing module is used for determining the position information of the data to be converted in the initial data based on the corresponding relation between the protocol identification of the initial data and the position information of the data to be converted;

And acquiring the data to be converted from the initial data based on the position information.

It should be noted that, in practical application, the proxy module may analyze all data packets generated by the protocol dedicated to 3GPP to obtain location information corresponding to data to be converted in each data packet, and may determine the location information of the data to be converted in the data packet directly based on the protocol identifier.

Based on the above, the data processing module can determine the corresponding relation between the protocol identifier of the initial data and the position information of the data to be converted after obtaining the initial data, determine the position information of the data to be converted in the initial data, and extract the data to be converted from the initial data based on the position information.

Step 606: and the data forwarding module forwards the target data to a data network.

The data network may be referred to the above description of the data processing system based on the wireless network, which will not be described in detail in this specification.

In the above example, in the autopilot scenario, after receiving the data packet carrying the environmental image information of the current position of the autopilot car sent by the proxy module, the switch can forward the data packet to a server capable of managing the autopilot car in the data network. The server processes the data such as the surrounding image of the automobile and the coordinate information of the automobile. It is also understood that, after receiving the data packet carrying the environmental image information of the current position of the automatic driving automobile sent by the proxy module, the switch forwards the data packet to a server capable of managing the automatic driving automobile through a data network.

The wireless network-based data processing method provided in the present specification further includes that the wireless network-based data processing system includes at least two base stations. While the mobile terminal is in connection with a base station, there may be a transition from one base station (base station a) to another base station (base station B). In this case, in order to ensure the performance of data transmission efficiency, stability, etc. of the base station and the mobile terminal. The terminal needs to be transferred from the base station a to the base station B, so that the connection between the mobile terminal and the data network is realized through the base station B, where it should be noted that the switching procedure for transferring the terminal from the base station a to the base station B may be any switching procedure capable of implementing base station switching, for example, an Xn switching procedure, an X2 switching procedure, and so on. This is not particularly limited in this specification. For example, one manner of switching the flow provided in this specification is as follows.

The data processing method based on the wireless network provided by the specification further comprises that the system comprises at least two base stations, wherein,

The method comprises the steps that an initial base station in at least two base stations receives a base station switching request uploaded by a terminal, wherein the base station switching request carries a target base station identifier; and

Generating a switching judgment request based on the base station switching request, and sending the switching judgment request to a target base station in the at least two base stations through the data processing module;

The target base station in the at least two base stations performs switching judgment based on the switching judgment request to obtain a judgment result, and sends the judgment result to the initial base station through the data processing module;

And the initial base station sends a switching agreement instruction to the terminal under the condition that the received judgment result is determined to agree to switch, so that the terminal connected with the initial base station is switched to be connected with the target base station.

The initial base station may be understood as a base station connected to the terminal among all the base stations, and the target base station may be correspondingly understood as a base station to which the terminal needs to be switched.

The base station handover request may be understood as a request that the terminal requests that the initial base station needs to perform a base station handover operation. In practical application, the terminal can detect the signal strength of surrounding base stations in real time, and when determining that base stations with stronger signal strength than the currently connected base stations exist around, the terminal sends a base station switching request to the currently connected base stations (i.e. initial base stations) in order to ensure the efficiency of data transmission. For example, the base station handover request may be a measurement report request.

A handover decision request may be understood as a request by the initial base station to decide whether the target base station is a base station that can be handed over. In practical application, part of base stations can only be connected with a specific terminal due to the requirement of practical application, or part of base stations can be set to be unconnectable, or in some scenes, the initial base station can only agree with the request of the terminal for switching to the target base station under the condition that the target base station is a self adjacent base station; therefore, in view of various requests including but not limited to those described above, the initial base station needs to determine whether the target base station is a base station capable of connecting with the terminal. Thus, the initial base station may send a handover decision request to the target base station.

The handover result may be understood as a result generated after the target base station determines whether or not it can connect with the terminal in response to the handover determination request, and the result may be a handover approval or a handover disapproval. In practical applications, after receiving the handover decision request sent by the initial base station, the target base station may detect whether its own communication resources (such as interface resources, data link resources, etc.) meet the needs of the terminal, or whether the target base station is configured as unable to connect, or whether the terminal is able to connect with the target base station, and generate a handover result.

The target base station identification may be understood as information uniquely characterizing the target base station, e.g., the number, ID, IP address, name, etc. of the target base station.

Along the above example, referring to fig. 4, after receiving a base station handover request sent by a terminal connected to a base station a in a data processing system based on a wireless network, a base station a can generate a handover decision request, and based on a base station B identifier carried in the base station handover request, send the handover decision request to a base station B through a proxy module C corresponding to the base station a.

After receiving the handover decision request, the base station B can respond to the handover decision request to detect whether the terminal handover can be performed, and generate a result indicating that the terminal can be migrated. And then the base station sends the result to the base station A through the corresponding proxy module D.

If the base station a determines that the result is that handover is acceptable, the base station a can send an acceptable handover command to a terminal that needs to perform base station handover, and instruct the terminal to handover to the base station B. In practical applications, the base station a disconnects the downlink with the terminal in the process of sending the handover grant instruction to the terminal.

After receiving the handover grant instruction, the terminal disconnects the uplink with the base station a and establishes a connection with the base station B. Thereby realizing the operation of switching the terminal from the base station A to the base station B.

In addition, in the case where the wireless network-based data processing method provided in the present specification is applied to an autopilot scenario, the autopilot car may involve a problem of moving from a wireless network coverage area of one base station to a wireless network coverage area of another base station due to movement of the car during traveling, in which case, in order to ensure quality of data transmission and stability of autopilot, it is necessary to switch from a currently connected base station to another base station. Referring to fig. 4, after receiving a base station switching request sent by an autopilot connected to a base station a (the base station currently connected to the autopilot) in a data processing system based on a wireless network, a base station a can generate a switching decision request, and send the switching decision request to the base station B through a proxy module C corresponding to the base station a based on a base station B (the base station to which the autopilot needs to be connected) carried in the base station switching request.

After receiving the switching decision request, the base station B can respond to the switching decision request to detect whether the automatic driving automobile can be switched or not, and generate a result indicating that the automatic driving automobile can be switched. And then the base station B sends the result to the base station A through the corresponding proxy module D.

If the base station a determines that the result is that the switching is authorized, the base station a can send an authorized switching instruction to the automated driving vehicle that needs to perform the base station switching, and instruct the automated driving vehicle to switch to the base station B.

In practical applications, the base station a disconnects the downlink with the autopilot during the process of sending a consent to switch instruction to the autopilot. After receiving the handover approval instruction, the autopilot vehicle disconnects the uplink with the base station a and establishes a connection with the base station B. Thereby realizing the operation of switching the automatic driving automobile from the base station A to the base station B.

In an embodiment provided in the present specification, the sending, by the data processing module, the handover decision request to a target base station of the at least two base stations includes:

an initial base station of the at least two base stations sends the handover decision request to the data processing module;

The data processing module receives a handover decision request sent by the initial base station and sends the handover decision request to a target base station in the at least two base stations based on the target base station identifier;

correspondingly, the sending, by the data processing module, the decision result to the initial base station includes:

The target base station in the at least two base stations sends the judgment result to the data processing module;

And the data processing module sends the received judgment result to the initial base station.

Along the above example, the signaling interaction process between the base station a and the base station B may be implemented through a corresponding proxy module, specifically, after the base station a generates a handover decision request, the handover decision request may be sent to the proxy module C, where the proxy module C sends the received handover decision request to the proxy module D, and the proxy module D issues the handover decision request to the base station B.

Correspondingly, after generating a result indicating that the terminal can migrate, the base station B can send the result to the corresponding proxy module D, the proxy module D sends the result to the proxy module C, and the proxy module C sends the result to the base station a.

Further, in the process that the base station a disconnects the downlink with the terminal, but the terminal does not establish a connection with the base station B, other terminals (such as other mobile phones, servers, etc.) that communicate with the terminal through the data network may send data to the base station a through the data network. In this case, the base station a caches the user plane data that needs to be sent to the terminal, and in order to avoid the problem that the data cannot be sent to the terminal, the base station a sends the data to the base station B, and the base station B continues to send the data to the terminal, so that the problem of data loss is avoided; the specific implementation mode is as follows.

And sending a handover approval instruction to the terminal so that the terminal connected with the initial base station is switched to be connected with the target base station, and further comprising:

the initial base station determines data to be sent corresponding to the terminal, and sends the data to be sent and the target base station identifier to the data processing module;

the data processing module receives the data to be sent and the target base station identifier, and sends the data to be sent to the target base station based on the target base station identifier;

and the target base station sends the received data to be sent to the terminal.

The data to be transmitted may be understood as data that needs to be transmitted to the terminal. For example, in the process of data communication between the terminal and other terminals, the data sent by other terminals to the terminal includes but is not limited to text data, multimedia data, etc.

Specifically, the initial base station sends a handover grant instruction to the terminal, so that the terminal connected with the initial base station is switched to be connected with the target base station, and then the received data to be sent, which needs to be sent to the terminal, is determined. And the data to be transmitted and the target base station identifier are transmitted to the corresponding data processing module.

And the data processing module sends the data to be sent to the target base station according to the target base station identifier after receiving the data to be sent and the target base station identifier. And the target base station resends the received data to be sent to the terminal.

In practical application, when the data processing module corresponding to the initial base station and the target base station is the same, the data processing module sends the data to be sent to the target base station based on the target base station identifier, which can be understood that the data processing module sends the data to be sent to the corresponding target base station according to the target base station identifier sent by the corresponding initial base station.

In the case that the data processing modules corresponding to the initial base station and the target base station are different, the data processing module sends the data to be sent to the target base station based on the target base station identifier, which can be understood that the data processing module sends the data to be sent to the data processing module corresponding to the target base station according to the target base station identifier sent by the corresponding initial base station; and then the data processing module corresponding to the target base station sends the data to be sent to the target base station.

In the embodiment provided in the present disclosure, after the base station is switched, in order to enable other terminals to quickly send data to the terminal, the proxy module may send dynamic route update to the corresponding switch, so as to implement adjustment on the route of the terminal. The specific implementation mode is as follows.

The data processing module corresponding to the initial base station sends a route deletion request to the corresponding data forwarding module;

And the data forwarding module deletes the route corresponding to the terminal based on the route deletion request.

The above examples are used. The proxy module C can send a route deletion request to the switch after determining that the base station A has disconnected from the terminal; and the switch responds to the route deletion request and withdraws the route of the original terminal.

Further, the sending a handover grant instruction to the terminal so that the terminal connected to the initial base station is switched to be connected to the target base station, further includes:

The data processing module corresponding to the target base station sends a route update request to the corresponding data forwarding module;

And the data forwarding module announces the route corresponding to the terminal based on the route update request.

The above examples are used. The proxy module D can send a route update request to the switch after determining that the terminal has been switched to the base station B; the switch announces the route of the terminal in response to the route update request.

According to the data processing method based on the wireless network, the initial data sent by the base station can be converted into the target data through the data processing module in the data processing system based on the wireless network, and the target data is sent to the data network through the corresponding data forwarding module, so that the problem of huge data transmission quantity of the core network due to the fact that all the base stations need to forward the data to the data network by the core network is avoided, the problem of low data transmission efficiency of the core network is further avoided, and the data transmission efficiency is improved.

Fig. 8 is a flowchart of a live broadcast data processing method based on a wireless network, which is applied to a live broadcast data processing system, and the system comprises a base station, a data processing module and a data forwarding module, and the method specifically comprises the following steps.

Step 802: the base station receives initial live broadcast data sent by the user terminal under the condition of live broadcast execution and sends the initial live broadcast data to the data processing module.

Step 804: the data processing module is used for receiving the initial live broadcast data sent by the base station, determining attribute information of the initial live broadcast data and determining a corresponding data network transmission protocol for the initial live broadcast data according to the attribute information; and

And converting the initial live broadcast data into target live broadcast data based on the data network transmission protocol, and sending the target live broadcast data to the data forwarding module.

Step 806: and the data forwarding module forwards the target live broadcast data to a live broadcast server through a data network.

For the explanation of the base station, the data processing module, the data forwarding module, and the data network transmission protocol, reference may be made to corresponding or corresponding descriptions in the data processing method based on the wireless network, which is not repeated herein.

The user terminal may be understood as a terminal in the above data processing method based on a wireless network, for example, the user terminal is a mobile phone; the initial live data may be understood as data generated based on a protocol used in the wireless network during live operation of the user terminal in the wireless network environment. In practical application, in the process of live broadcasting through a mobile phone, a user encapsulates image data collected by an image collecting device (such as a camera) configured on the mobile phone into a data packet or a data message through a protocol used in a wireless network, so that the base station can process the image data. For the description of the initial live broadcast data, reference may be made to the description content of the initial data in the data processing method based on the wireless network, which is not repeated herein.

Accordingly, the attribute information of the initial live broadcast data includes, but is not limited to, a protocol identifier corresponding to the initial live broadcast data, base station identifier information corresponding to the initial live broadcast data, and the like, where the attribute information is used as the protocol identifier corresponding to the initial live broadcast data, and the protocol identifier is used to uniquely identify a protocol for generating the initial live broadcast data. For example, the initial live broadcast data is a data message generated based on a GTP protocol; the attribute information of the initial live broadcast data is the identifier of the GTP protocol, where the identifier may be a number, an ID, a name, etc.

The target live broadcast data can be understood as a data message which is generated based on the repackaging of the routing protocol, and the data message can be forwarded by a switch and a router. The data message contains live broadcast data generated by the user terminal in the live broadcast executing process, wherein the live broadcast data comprises but is not limited to image data, multimedia data and the like.

A live server may be understood as a server capable of processing live data in a live scene, for example, a live server, a live platform, etc.

The application of the live broadcast data processing method based on the wireless network in a live broadcast scene is taken as an example, and the live broadcast data processing method based on the wireless network is described below, wherein in the live broadcast scene, the terminal can be a mobile phone, and the initial data can be understood as live broadcast image data sent by the mobile phone to a base station; based on the method, in the live broadcast process of the mobile phone, the mobile phone can acquire live broadcast image data in real time and send the live broadcast image data to the base station in the form of a data packet. The base station, after receiving the data packet containing live image data, can send the data packet to the proxy module.

Since the current environmental data is a data packet generated based on the 3GPP communication protocol, the data packet cannot be forwarded by an interworking machine, a router, etc. in the data communication network. Therefore, the proxy module needs to convert the data packet through a routing protocol to obtain a data packet capable of being transmitted in the data network. Specifically, the proxy module can determine a protocol identifier corresponding to the data packet, determine a corresponding routing protocol for the data packet based on the protocol identifier, and convert the data packet transmitted under the mobile communication network into a data packet forwarded in the IT network based on the routing protocol. In the process of generating the data packet forwarded in the IT network based on the routing protocol, the method may be: and packaging the data packet transmitted under the mobile communication network based on the routing protocol to obtain the data packet forwarded in the IT network. Or the proxy module extracts live image data acquired by the mobile phone in the live broadcast process from the data packet transmitted by the mobile communication network, and encapsulates the live image data based on the routing protocol to obtain the data packet forwarded in the IT network. And sends the data packet to the switch.

After receiving the data packet carrying the live image information sent by the proxy module, the switch can forward the data packet to a live server in the data network (the live server can be understood as a server capable of processing live data). So that the live broadcast server processes live broadcast environment images. It is also understood that, after receiving the data packet carrying live image information sent by the proxy module, the switch forwards the data packet to the live server through the data network.

The live broadcast data processing method based on the wireless network is applied to a live broadcast data processing system based on the wireless network, after initial data sent by a base station is received through a data processing module in the system, the initial live broadcast data can be converted into target live broadcast data, and the target live broadcast data is sent to a data network through a corresponding data forwarding module, so that the problem that the data transmission quantity of the core network is huge due to the fact that all the base stations need to forward the live broadcast data to the data network is avoided, the problem that the live broadcast data transmission efficiency of the core network is low is further avoided, the live broadcast data transmission efficiency is improved, and the live broadcast quality is guaranteed.

The method for processing the live broadcast data based on the wireless network provided by the specification further comprises at least two base stations in the live broadcast data processing system based on the wireless network. While the user terminal is connected to the base station, there may be a case where it is transferred from one base station (base station a) to another base station (base station B). For example, the user may move during live broadcast, and during moving, the problem of moving from the wireless network coverage area of one base station to the wireless network coverage area of another base station may be involved, in this case, in order to ensure the efficiency of data transmission and improve the quality of live broadcast, the terminal needs to be transferred from the base station a to the base station B, so that the connection between the user terminal and the data network is implemented through the base station B, where it needs to be noted that the handover procedure for transferring the terminal from the base station a to the base station B may be any handover procedure capable of implementing base station handover, for example, an Xn handover procedure, an X2 handover procedure, and so on. This is not particularly limited in this specification. For example, one manner of switching the flow provided in this specification is as follows.

The system comprises at least two base stations, wherein,

The method comprises the steps that an initial base station in at least two base stations receives a base station switching request uploaded by a user terminal under the condition of live broadcast execution, wherein the base station switching request carries a target base station identifier; generating a switching judgment request based on the base station switching request, and sending the switching judgment request to a target base station in the at least two base stations through the data processing module;

and the initial base station sends a switching agreement instruction to the user terminal under the condition that the received judgment result is determined to agree to switch, so that the user terminal connected with the initial base station is switched to be connected with the target base station.

The base station switching request, the switching decision request, the switching result, the target base station identifier and the handover agreement instruction may refer to corresponding or corresponding descriptions in the data processing method based on the wireless network, which is not repeated herein.

Along the above example, in the process of live broadcasting through the user terminal, the user terminal may be involved in moving from the wireless network coverage area of one base station to the wireless network coverage area of another base station, in which case, in order to ensure the efficiency of data transmission and the stability of live broadcasting, it is necessary to switch from the currently connected base station to another base station. Referring to fig. 4, after receiving a base station switching request sent by a mobile phone connected with a base station a (a base station currently connected with a mobile phone performing live broadcast operation) in a data processing system based on a wireless network, a base station a can generate a switching decision request, and based on a base station B (a base station to which the mobile phone performing live broadcast operation needs to be connected) identifier carried in the base station switching request, the switching decision request is sent to the base station B through a proxy module C corresponding to the base station a.

After receiving the handover decision request, the base station B can detect whether the mobile phone handover is possible in response to the handover decision request, and generate a result indicating that the mobile phone is possible to handover. And then the base station sends the result to the base station A through the corresponding proxy module D.

If the base station A determines that the result is that the handover is authorized, the base station A can send an authorized handover instruction to the mobile phone which needs to be handed over to the base station B. The handset establishes a connection with the base station B. Thereby realizing the operation of switching the automatic driving automobile from the base station A to the base station B.
