Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic diagram of a network architecture of a network capability opening method according to an embodiment of the present invention. The CPE network element is connected with a plurality of devices, which may be, for example, user devices or sensors, and the plurality of devices and the CPE network element are connected through a local area network. A base station (shown by gNB in the figure) is connected between the CPE network element and a User Plane Function (UPF) entity, and the UPF entity communicates with the base station through an N3 interface. The CPE network element may transmit the device information of the plurality of devices to the UPF entity through the base station, and the UPF entity may transmit the device information to the server through the N6 interface and the mobile network. And, the UPF entity and the UPF entity can communicate through an N9 interface.

Optionally, the CPE network element may also be referred to as a CPE-like network element.

As shown in fig. 2, which is a schematic flow chart of a network capability opening method according to an embodiment of the present invention, the method is applied to a first user plane function UPF entity, and includes:

s201: acquiring uplink service message information transmitted by a base station when a CPE network element of a client device accesses the base station connected with the first UPF entity;

Before step S201, the CPE network element obtains device information of a device accessed by the CPE network element.

The device information includes, but is not limited to, a Media Access Control (MAC) address, an Internet Protocol (IP) address, a device model, a device runtime, a Central Processing Unit (CPU) utilization rate, a memory utilization rate, a hard disk usage, and a device reboot time.

In step S201, when the CPE network element accesses a base station, the uplink service packet information is transmitted to a first UPF entity connected to the base station through the base station. Correspondingly, the first UPF entity obtains the uplink service message information transmitted by the base station when the CPE network element of the client equipment accesses the base station connected with the first UPF entity.

By adopting the network capacity opening method provided by the embodiment of the invention, the first UPF entity can acquire the equipment information of the equipment accessed in the CPE network element connected with the base station through the base station, and the first UPF entity can provide the equipment information under the first UPF entity for other UPF entities by acquiring the equipment information of the equipment accessed in the CPE network element, so that the problem that other UPF entities, other network elements or applications with requirements repeatedly acquire the equipment information through a server is avoided, the efficiency of acquiring the equipment information of the equipment accessed in the CPE network element is improved, and the utilization rate of network resources is improved. Optionally, the first UPF entity and the CPE network element may communicate via SRv6 or IPv6 protocols. Illustratively, the uplink service message information is transmitted through SRv6 messages, or through IPV6 messages. That is, the CPE network element transmits the uplink service packet information to the base station through the SRv6 packet or the IPV6 packet, and the base station retransmits the uplink service packet information to the first UPF entity using the same packet (SRv6 packet or IPV6 packet).

In the embodiment of the invention, the CPE network element and the first UPF entity communicate in a diversified communication mode, so that the integrity and the accuracy of the uplink service message information transmitted by the CPE network element can be improved. For example, when the CPE network element transmits the uplink service packet information by using one communication protocol, data loss occurs, and then the CPE network element may transmit the uplink service packet information by using another communication protocol, thereby ensuring the integrity and accuracy of the uplink service packet information.

Illustratively, the device information is carried by a TLV field in an extension header of the SRv6 packet or the IPv6 packet.

SR, Segment Routing, is a source Routing technology, and source Routing is implemented by carrying labels of nodes of a forwarding path in a packet of a head node, SRV6 is an SR based on IPV6 forwarding plane, and IPV6 implements reachability.

Fig. 3 is a message format diagram of an extension header of SRv6 and IPv6 in the network capability opening method according to the embodiment of the present invention. The Next field of the IPv6 header is 43, which indicates that the subsequently carried header is a Routing extension header, and the Routing Type field in the Routing extension header, which identifies the Type of the Routing header, is 4, which indicates that the field is the SR header of SRv 6.

The SRV6 is compatible with IPv6 routing forwarding, connection among different network domains is easier to realize based on IP reachability, and the affinity of SRv6 for IPv6 enables the IP bearer network to be seamlessly fused with applications supporting IPv6, so that more possible value-added is brought to operators through network perception application.

Specifically, the SRv6 and the contents included in the extension header of the IPv6 are as shown in fig. 3.

(1) Segment List: ordered SRv6 Sid list

(2) Number of intermediate nodes Segment Left (SL) that should still be accessed before reaching the destination node: segment Identifier SRv6 (SID) is slit SL. In the forwarding process, the SL is modified, and the SID with the DIP being active is changed to finish the forwarding.

(3) Version: version(s)

(4) Traffic Class: type of flow

(5) Flow Label: flow label

(6) Pload Length: payload length

(7) Hop Limit: hop count limitation

(8) Source Address: source address

(9) Destination Address: destination address

(10) Next Header: the type of header immediately following the SRH is identified.

(11) Hdr Ext Len: length of SRH head.

(12) Last Entry: the index of the last element of the segment list is contained in the segment list.

(13) Flag: some identification of the packet.

(14) Tag: identifying the same group of packets for grouping the packets, a group-based policy may be implemented.

(15) Optional Tlv objects (variable): variable length TLV part

(16) IPv6 Payload: message load

(17) IPv6 Header: IPv6 extension header

(18) SR Header: SR expansion head

Segment routing header type, length, value SRH TLVs (NSH metadata, HMAC TLV, Padding TLV, etc.): a global parameter that can be used in common as the SID of the Segment List.

The SRH TLVs may carry device information such as a MAC address, an IP address, a device model, device running time, a CPU utilization rate, a memory utilization rate, a hard disk usage, and device reboot times of the device.

Optionally, when the CPE-like network element uplink service packet information is accessed to the mobile network, the TLV field of the SRv6 extension header carries the device information such as the MAC address, the IP address, the device model, the device running time, the CPU utilization rate, the memory utilization rate, the hard disk usage, the device reboot times, and the like of the network element downlink device.

When receiving SRv6 equipment information of extension head-carried CPE network element down-link equipment, the UPF entity analyzes SRv6 messages and stores, maintains and ages the carried equipment information.

Optionally, the UPF entity only maintains the device information of the CPE-like network element downlink device accessed through the base station served by the UPF entity, and provides a restful, netconf, or other api interface for the application in need to make the capability request call, and the UPF entity also supports other network elements or applications to make the capability request call through the function defined in an embodiment of the present invention.

For example, the first UPF entity may further store the device information.

Further, the first UPF entity may also update the device information when the device information is updated.

The CPE network element may send device information of one or more devices connected to the CPE network element to the base station, and the base station may send the device information to the UPF entity connected to the base station. The UPF entity may then store this device information.

Further, the UPF entity may also transmit the device information to a server for backup. The first UPF entity may maintain the device information accessed to the CPE and monitor whether the device information changes every time a preset time period elapses, for example, the time period may be 30 minutes or 1 hour or 1 day. When the device information changes, for example, the device information increases or decreases, the device information is updated. By updating the device information when the device information changes, the validity and accuracy of the device information can be improved. The first UPF entity is convenient for other UPF entities or applications to call the equipment information through interfaces by storing the equipment information, so that the other UPF entities or applications are prevented from repeatedly acquiring the equipment information through CPE network elements, and the utilization rate of network resources is improved.

Optionally, the method further comprises:

In one embodiment, the first UPF entity may actively report the device information of the device accessed by each CPE network element to the capability openness service platform; in another embodiment, the capability openness service platform may also actively collect the device information of the device accessed by each CPE network element on the first UPF entity, and collect the device information of the device accessed by each CPE network element on each UPF entity. The capability openness service platform can open the equipment information to the network element or application with the equipment information requirement by collecting the equipment information of the equipment accessed on each CPE network element stored on each UPF entity. As shown in fig. 4, a second flowchart of the network capability opening method according to the embodiment of the present invention is shown, and on the basis of step S201, the method further includes the following steps:

s401: the first UPF entity obtains the capability calling request sent by the second UPF entity.

The second UPF entity may send a capability invocation request to the first UPF entity. Accordingly, the first UPF entity may obtain the capability invocation request sent by the second UPF entity.

S402: the first UPF entity sends response information responding to the capability calling request to the second UPF entity; the response information comprises the equipment information of the target CPE network element requested by the capability calling request.

When receiving the capability calling request sent by the second UPF, the first UPF entity may analyze the capability calling request, and send response information responding to the capability calling request to the second UPF entity according to the analysis result, so that the second UPF entity may obtain the device information of the target CPE network element.

For example, when the second UPF entity needs to obtain one of the pieces of device information of the target device in the first UPF entity, a capability calling request may be sent to the first UPF entity, where the capability calling request includes the piece of device information requested by the second UPF entity, and the one of the pieces of device information may be, for example, a running time of the target device. When the first UPF entity receives the capability calling request of the second UPF entity, the capability calling request can be analyzed, and the device information requested by the second UPF can be sent to the second UPF entity in a response information mode. Therefore, the second UPF entity can directly obtain the running time of the target equipment from the first UPF entity without obtaining the running time of the target equipment through a CPE network element which is accessed to the same base station with the first UPF entity, the running time of the target equipment which is repeatedly obtained through the same CPE network element is avoided, and the utilization rate of network resources is improved.

Optionally, the second UPF entity may also obtain other information in the device information of the target device through the first UPF entity, for example, obtain a device model of the target device. The target device may be one device or a plurality of devices; the device information of the target device may be, for example, multiple information in the device information of one device, such as an IP address, an MAC address, and a memory utilization rate, or may be, for example, the same information in the device information of multiple devices, such as a hard disk usage, or may be, for example, multiple information in the device information of multiple devices.

Next, the manner in which the first UPF entity obtains the capability invocation request and sends the response information to the second UPF entity is described. Illustratively, the capability invocation request is obtained and the response information is sent to the second UPF entity by at least one of:

API interfaces, SRv6 messages, and IPv6 messages.

Optionally, the capability call request may also be acquired through restful or netconf, and the response information may also be sent to the second UPF entity.

Through various interfaces and messages of different types, the first UPF entity can acquire the capability calling request sent by the second UPF entity and send response information to the second UPF entity, and compatibility of the UPF entity is improved.

For example, when the capability call request sent by the second UPF entity is acquired through the SRv6 message and the response information is sent to the second UPF entity, the addressing address, the function information, and the carried parameters of the SRv6 message are recorded through the Segment List field in the SRv6 message used for sending the capability call request and the response information.

SRv6, the extension Header (SRH) is composed of a series of Security Identifiers (SIDs) and an optional TLV (Type-Length-Value), each SID is composed of 128 bits, and the 128 bits are divided into three parts, namely, location identifier, Function and variable alignment, and the Length of each part can be flexibly defined as long as the total Length of the three parts is 128 bits. The Locator is configured to record an addressing address of the SRv6 packet, the Function is configured to record Function information of the SRv6 packet, and the Argumen is configured to record parameters carried by the SRv6 packet. Specifically, as shown in fig. 5, it is an extension header schematic diagram of SRv6 of the network capability method according to the embodiment of the present invention.

Alternatively, one embodiment of the invention uses 32 bits to represent Locator, 32 bits to represent Function (two functions are defined), and 32 bits to represent archive. The acquisition of CPE-like network element downstream device information via SRv6 is achieved by defining 2 functions, one definition of which is shown in table 1:

TABLE 1

For example, the function information indicates that the SRv6 message is the capability call request through first preset field information, and indicates that the SRv6 message is the response information through second preset field information.

Specifically, the first preset field may be 0x00000001 as described above, and the second preset field may be 0x00000002 as described above.

For example, the parameter carried in the Segment List field of the SRv6 message is an address of the target CPE to be acquired.

By carrying the address of the target CPE to be acquired in the Segment List field of the SRv6 message, the address of the target CPE can be forwarded as the destination address. Therefore, the first UPF entity can know that the second UPF needs to acquire the equipment information of which CPE network element in the same base station the second UPF accesses, and then sends the equipment information in the target CPE network element to the second UPF entity, so that the accuracy and convenience for acquiring the equipment information of the target CPE network element access equipment are improved.

Further, on the basis of the above embodiments, a process of the second UPF entity acquiring the device information of the target device under the first UPF entity is specifically described next. For convenience of description, the second UPF entity is represented by UPF network element Z and the first UPF entity is represented by UPF network element a.

Fig. 6 is a schematic diagram illustrating request and response device information between UPF entities in the network capability opening method according to the embodiment of the present invention. Assuming that the UPF network element Z needs to acquire the device information of the CPE network element 10.10.10.10 downlink device maintained by the UPF network element a, where the device information of the CPE network element 10.10.10 downlink device is carried by a TLV field of an SRH header, the network element Z executes step S401 and constructs an SRv6 address according to the above-defined Function encoding rule. After receiving the capability call request of the network element Z, the network element a finds that the Function is 2 and the Argument is 10.10.10.10, and further analyzes the TLV field in the SRH header of the message according to table 2, recognizes that the network element Z requests the device information of the CPE network element 10.10.10.10 downlink device locally maintained by the network element a, and executes step S402, so that the network element Z obtains the related information of the CPE network element 10.10.10.10 downlink device. The specific format of the TLV field of the SRH header is shown in table 2:
