The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

It should be noted that the embodiment of the present invention is described by using a terminal network element as an example of a network element. Further, the terminal network element is described by using an IPv6 terminal as an example, but is not limited thereto.

FIG. 1 is a schematic flowchart of a method according to a first embodiment of the present invention, including:

Step 11: The terminal network element receives the first packet, where the first packet includes an IPv6 anycast address, where the terminal network element is an IPv6 terminal, and when the IPv6 terminal and the OMC transmit the packet through the router, The first packet may be a Neighbour Solicitation (NS) packet sent by the router in the same network segment as the IPv6 terminal, where the NS packet is an IPv6 anycast address and public configuration information sent by the router to the 0MC. The message was sent after the message. In the embodiment of the present invention, the packet that is sent by the OMC and includes the IPv6 anycast address and the common configuration information is called an OM-ping packet. That is, the NS packet is sent after the router receives the OM-ping packet sent by the OMC.

When the IPv6 terminal and the OMC directly transmit packets, the first packet is the OM-ping packet.

The IPv6 address is 128 bits long. The addresses are classified into three types according to their transmission type, namely, Unicast Address, Multicast Address, and Anycast Address. The unicast address and the multicast address already exist in IPv4. The anycast address is a new member in IPv6. The anycast address in the IPv6 address structure is defined as the identifier of a series of network interfaces (usually belonging to different nodes). : A packet destined for an anycast address will be forwarded to a "nearest" network interface identified by the address (the "recent" definition is based on the distance metric in the routing protocol). In the embodiment of the present invention, the last 64 bits of the IPv6 anycast address may be generated according to the Media Access Control (MAC) address, and the network segment where the terminal network element is located is used as the head of the IPv6 anycast address. The tail 64 bits of the ιρ _ν 6 anycast address is called a 64-bit extended unique identifier (EUI-64) and can be generated by a MAC address. That is, the format of the IPv6 anycast address is: Subnet segment of the subnet where the terminal NE is located: EUI-64.

The EUI-64 in this embodiment may be referred to as a specific EUI-64, that is, the IPv6 anycast address is: a subnet segment of the subnet where the terminal network element is located:: Specific EUI-64.

This particular EUI-64 can be generated as follows:

First, the equipment vendor or operator applies for its own MAC prefix;

Secondly, the equipment provider or the operator can define its own dedicated MAC address by different device types or application types, and the dedicated MAC address can be multiple; wherein the dedicated MAC address can be divided into 64 bits and 48 bits. Regardless of the length of the dedicated MAC address, the MAC prefix applied in the previous step is the only identifier for the vendor.

Again, EUI-64 is generated from the dedicated MAC address, which is the specific EUI-64. The EUI-64 generated by the MAC address can be implemented by using an existing method.

The OMC has the public configuration information of the terminal network element. Therefore, the OMC can carry the public configuration information of the terminal network element in the packet and send it to the terminal network element. The public configuration information may include: an OMC address. Of course, the OMC may also include formal configuration information corresponding to each terminal network element. After the terminal NE is successfully registered with the OMC, the OMC may send the formal configuration information to the terminal network element.

In the IPv6 protocol, if the operation and maintenance center (OMC) pings an unassigned IPv6 address, it can trigger the router to send an NS message for address resolution. The unassigned IPv6 address is assigned to an IPv6 terminal. The IPv6 terminal may be a base station (eNodeB).

Step 12: After receiving the first packet, the terminal network element determines whether a packet sent by another network element indicating that the IPv6 anycast address is used is received within a preset time. If not, it determines that the IPv6 is used by the terminal. Anycast address; In order to avoid the problem that the terminal network element is in conflict with the first packet, the number of times of receiving the first packet may be determined to be a preset number of times before the foregoing determining. The specific process may be: if the IPv6 terminal receives After the number of times the first packet is greater than the preset number of times, it is determined whether the packet sent by another network element indicating that the IPv6 anycast address is used is received within the preset time. If not, it is determined to use the packet. IPv6 anycast address.

Step 13: After determining that the IPv6 anycast address is used by the terminal network element, the public configuration information is obtained from the received OMC-containing packet containing the common configuration information, where the public configuration information includes the address of the OMC.

For example, when the IPv6 terminal communicates with the OMC through the router, the IPv6 terminal sends a Neighbor Advertisement (NA) message to the router after determining that the IPv6 anycast address is used by the IPv6 terminal. After receiving the NA message, the router receives the NA message. The OM-ping packet from the OMC is sent to the IPv6 terminal; the IPv6 terminal obtains the public configuration information from the OM-ping packet.

Or, when the IPv6 terminal directly communicates with the OMC, the IPv6 terminal obtains the public configuration information directly from the OM-ping packet after determining that the IPv6 anycast address is used by the IPv6 terminal.

Step 14: The terminal network element performs network registration with the OMC according to the address of the OMC. After the network is registered with the OMC, the OMC may send the formal configuration information of the IPv6 terminal corresponding to the terminal network element to the IPv6 terminal.

In addition, the public configuration information may further include: a virtual local area network (VLAN) configuration information, and then the IPv6 terminal configures the VLAN according to the VLAN configuration information. Alternatively, the public configuration information may further include an address of a dynamic host configuration protocol (DHCP) server, and then the IPv6 terminal obtains a unicast IPv6 address from the DHCP server according to the address of the DHCP server.

In this embodiment, the public configuration information from the OMC is sent to the terminal network element through the IPv6 anycast address, and the end-to-end configuration of the common configuration information can be implemented to avoid the problem that the public configuration information is configured in the terminal network element. In addition, the embodiment may be applied to a scenario in which a terminal network element directly communicates with an OMC, and may also be applied to a scenario in which a terminal network element communicates with an OMC through a router. FIG. 2 is a schematic flowchart of a method according to a second embodiment of the present invention. In this embodiment, an IPv6 terminal obtains public configuration information sent by an OMC.

Step 201: After the IPv6 terminal is started, the NS message in the VLAN is monitored by joining the multicast group.

For example, an IPv6 terminal adds itself to a multicast group with a multicast address of FF02::1:FF: (the lower 24 bits of the EUI-64), and can listen to NS packets in the VLAN. Assuming that the specific EUI-64 is lower 24 bits = 11: 1111, the multicast address added by the IPv6 terminal is FF02::1:FF: 11:1111.

Step 202: The IPv6 terminal generates a random number N, and sets the counter value C1 to zero. For example, setting 3<N<10, C1=0.

Step 203: The IPv6 terminal waits for the destination address (DIP) = the pre-configured multicast address, and the request destination address is the NS message of the pre-configured anycast address.

The NS packet carries the "destination address" and the "request destination address," for example. The pre-configured multicast address is: FF02::1:FF: 11:1111, and the subnet prefix of the IPv6 terminal is 2001:: , the pre-configured anycast address is: 2001: specific EUI-64. At this time, the IPv6 terminal waits for the "destination address, which is FF02::1:FF: 11:1111, "Request destination address, NS message for 2001: specific EUI-64.

Step 204: The OMC queries the subnet prefix of the IPv6 terminal, and generates an IPv6 anycast address in the network segment according to the subnet prefix.

For example, with the prefix 2001:: as an example, the generated IPv6 anycast address is: 2001:: Specific EUI-64.

Step 205: The OMC sends an OM-ping packet to the network segment, where the packet includes public configuration information, such as a VLAN, a DHCP-Server address, and an OMC address.

For example, the source address of the OM-ping address is SIP=OMC's IPv6 address, and the destination address is DIP=2001::specific EUI-64. Suppose the specific EUI-64=device vendor MAC prefix: 11:1111, then DIP=2001 :: Equipment vendor MAC prefix: 11:1111.

Step 206: The OM-ping packet reaches the router of the subnet where the IPv6 terminal is located, the router Query the neighbor table entry. If the address is not used by other terminals, the router caches the OM-ping packet.

The address of each terminal can be recorded in the neighbor table entry.

Step 207: The router sends an NS multicast packet, and waits for the IPv6 terminal that uses the IPv6 anycast address to reply to the NA^ message.

For example, the NS multicast packet DIP= FF02::1:FF: 11:1111, and the request destination address is: 2001:: Device vendor MAC prefix: 11:1111.

Step 208: After receiving the NS message, the IPv6 terminal starts counting, that is, performs C 1 + 1 processing.

The IPv6 terminal can perform the counting process after receiving the NS message waiting for the NS message, because the NS message is the NS message waiting for the IPv6 terminal.

Step 209: The IPv6 terminal determines whether the counted C1 is equal to N. If yes, go to step 210. Otherwise, go to step 203.

That is, if C N is counted, it continues to listen until C1 = N.

Step 210: Determine whether the NA message corresponding to the NS message address broadcast by the other IPv6 terminal is received in the random time T1. If yes, go to step 202. Otherwise, go to step 211.

Where T1 is a random delay and can be set to 10ms<Tl<100ms. It can be determined that the other IPv6 terminals broadcast the NA message after receiving the NS message, and the other IPv6 terminals can be broadcasted after receiving the NS message. At this time, step 203, step 208, and step 209 may not be performed.

Step 211: The IPv6 terminal automatically configures the Link-local address.

The automatically configured Link-local address includes: a first 64 bits of a fixed specific value, and a last 64 bits of the EUI-64 of the terminal itself.

Step 212: The IPv6 terminal uses the link-local address to reply to the router with an NA message, and announces that it uses the IPv6 anycast address.

Specifically, the SIP=link-local address of the NA^艮文, the IP address of the DIP router. At the same time, the IPv6 terminal can send "unsolicited NA" to broadcast itself to the local network segment where it is located (2001::specific EUI-64). The purpose of this "unsolicited NA" (broadcast NA) is to prevent other terminal network elements in the same network segment from competing for the same address at the same time. Moreover, in conjunction with the random delay T1, the possibility of contention between the terminal network elements is minimized. In addition, to prevent the router from curing the neighbor entry, for example, to prevent the router from binding the IPv6 anycast address to the MAC address of the IPv6 terminal, the FLAG of the "override" is set to "not overwrite" in the sent NA message.

Step 213: After receiving the NA packet, the router forwards the OM-ping packet to the IPv6 terminal. Step 214: The IPv6 terminal determines whether the packet is received. If yes, go to step 215. Otherwise, go to step 202.

Step 215: The IPv6 terminal determines whether the packet is an OM-ping packet. If yes, go to step 216. Otherwise, go to step 217.

The difference between the OM-ping and the normal ping in the embodiment of the present invention is that the OM-ping packet in the embodiment of the present invention carries the public configuration information, and can be judged according to whether the public configuration information is carried. Whether it is an OM-ping message.

Step 216: The IPv6 terminal learns various information in the OM-ping packet, that is, obtains the public configuration information from the OM-ping packet.

The public configuration information includes an OMC address, and the IPv6 terminal can register with the OMC according to the OMC address. After the registration is complete, the IPv6 terminal can obtain the official configuration information of the corresponding terminal network element from the OMC. The IPv6 terminal can use the VLAN configuration information in the OM-ping packet to configure the VLAN. If there is a new requirement for the Link-Local address in the OM-ping packet, reconfigure the Link-Local address according to the new requirement.

The OMC receives the registration message, records that the NE has received the OM-ping, and can continue to send the OM-ping until all the terminal NEs in the subnet are successfully registered.

Step 217: The IPv6 terminal discards the packet and stops the learning process on the configured IPv6 anycast address (the suffix of the configured IPv6 anycast address is 11:1111).

Step 218: Determine whether all learning processes fail, and if yes, perform step 219, otherwise, Go to step 202.

Step 219: Record the failure result and end the learning process.

In this embodiment, the IPv6 anycast address configured by the OMC can be used to obtain the public configuration information of the OMC configuration and implement the end-to-end configuration of the common configuration information.

In this embodiment, it is possible to prevent the terminal network element from colliding when acquiring the IPv6 anycast address by determining whether the received NS message reaches the preset number of times and determining whether the other terminal network element replies to the NS message sent by the router.

This embodiment can be applied to a scenario in which a terminal network element communicates with 0 M C through a router.

After obtaining the public configuration information, the terminal may perform different registration processes of the OMC according to different acquisition methods of the unicast IP address. For details, refer to the following embodiments.

FIG. 3 is a schematic flowchart of a method according to a third embodiment of the present invention. This embodiment takes an automatic configuration of a global unicast address as an example. Referring to FIG. 3, this embodiment includes:

Step 31: The IPv6 terminal obtains the OM-ping packet sent by the OMC through the IPv6 anycast address. Step 32: The IPv6 terminal obtains the public configuration information from the OM-ping packet.

For the specific implementation of the above two steps, reference may be made to the second embodiment.

Step 33: The IPv6 terminal uses the global unicast address autoconfiguration process to configure a unicast IPv6 address. Specifically, the configured unicast IPv6 address may include: a first 64 bits and a last 64 bits, where the first 64 bits are subnet segments to which the IPv6 terminal belongs, and may be obtained from VLAN configuration information; the last 64 bits are terminals. Its own EUI-64, in which the terminal's own EUI-64 is obtained according to the MAC address of the terminal.

Step 34: The IPv6 terminal sends a first notification message to the OMC according to the unicast IPv6 address configured in the global unicast address auto-configuration process, where the first notification message notifies the network element identifier of the terminal network element and the configured unicast IPv6 address. Correspondence to achieve registration with the OMC.

Specifically, the first notification message is used to notify the OMC that the IPv6 terminal has received the OM-ping packet, and notifies the OMC of the unicast IPv6 address of the IPv6 terminal and the network element identifier of the IPv6 terminal.

The public configuration information includes an OMC address for the terminal to communicate with the OMC. In addition, the OMC can determine whether the terminal network element is successfully registered according to the first notification message sent by the terminal network element, and so on, and the OMC can determine whether each terminal network element is successfully registered, that is, determine all terminal networks in the subnet. If the registration is successful, the OM-ping packet will be sent after the registration is successful. Otherwise, the OM-ping packet will continue to be sent.

Step 35: After the IPv6 terminal successfully registers with the OMC, it can also perform authentication, authentication, and formal configuration information for the terminal entity.

In this embodiment, the public configuration information is obtained through the IPv6 anycast address, and the unicast IPv6 address configuration is completed according to the global unicast address automatic configuration process, so that OMC registration is not required.

An IPv6 anycast address is a unicast IPv6 address. It can allocate common configuration information to multiple IPv6 terminals through an IPv6 anycast address.

FIG. 4 is a schematic flowchart of a method according to a fourth embodiment of the present invention. Different from the third embodiment, this embodiment obtains a self-unicast IPv6 address through a DHCP process. See Figure 4, including:

Step 41: The IPv6 terminal obtains the OM-ping packet sent by the OMC through the IPv6 anycast address. Step 42: The IPv6 terminal obtains public configuration information from the OM-ping packet.

Step 43: The IPv6 terminal uses the DHCP process to configure a unicast IPv6 address.

The public configuration information may include an address of the DHCP server to perform a DHCP process. Step 44: The IPv6 terminal sends a first notification message to the OMC according to the unicast IPv6 address configured by the DHCP process, where the first notification message notifies the correspondence between the network element identifier of the terminal network element and the configured unicast IPv6 address to implement Registration to the OMC.

The OMC address can be included in the public configuration information.

In addition, the OMC can determine whether the terminal network element is successfully registered according to the first notification message sent by the terminal network element, and so on, and the OMC can determine whether each terminal network element is successfully registered, that is, determine all terminal networks in the subnet. Whether the yuan is registered successfully, stop sending OM-ping after the registration is successful. Packet, otherwise continue to send OM-ping packets.

Step 45: After the IPv6 terminal successfully registers with the OMC, it can also perform authentication, authentication, and formal configuration for the terminal entity.

In this embodiment, the public configuration information is obtained through the IPv6 anycast address, and the unicast IPv6 address configuration is completed according to the DHCP configuration process to perform the OMC registration, and the IPv6 anycast address is not required to be the unicast IPv6 address, and the IPv6 address can be achieved. Anycast address assigns common configuration information to multiple IPv6 terminals. In addition, the unicast IPv6 address is obtained in different ways, and the unicast IPv6 address acquisition mode is diversified.

FIG. 5 is a schematic flowchart of a method according to a fifth embodiment of the present invention. Different from the third and fourth embodiments, the embodiment uses an IPv6 anycast address as its unicast IPv6 address. See Figure 5, which includes:

Step 51: The IPv6 terminal obtains the OM-ping packet sent by the OMC through the IPv6 anycast address. Step 52: The IPv6 terminal obtains the public configuration information from the OM-ping packet.

Step 53: The IPv6 terminal configures the IPv6 anycast address as its own unicast IPv6 address.

Step 54: The IPv6 terminal uses the unicast IPv6 address to send a second notification message to the OMC, and the second notification message notifies the mapping between the network element identifier of the terminal network element and the configured unicast IPv6 address to implement the OMC. Register and instruct the OMC to suspend the sending of anycast address in this segment.

Specifically, the second notification message is used to notify the OMC that the IPv6 terminal has received the OM-ping packet, and notifies the OMC of the unicast IPv6 address of the IPv6 terminal and the network element identifier of the IPv6 terminal, and instructs the OMC to suspend the The transmission of the IPv6 anycast address in the network segment.

Step 55: After receiving the second notification message, the OMC temporarily stops the learning process in the network segment (2001::).

Step 56: At the same time, the IPv6 terminal broadcasts a Router Advertisement (RA) message, where "override" is an overlay, indicating that the IPv6 anycast address is occupied by the IPv6 terminal.

Step 57: The IPv6 terminal acquires a new unicast IPv6 address, for example, using a global unicast address. The unicast IPv6 address obtained by the automatic configuration process or DHCP process.

Step 58: The IPv6 terminal sends a third notification message to the OMC, where the third notification message indicates that the OMC continues to send the packet in the local network segment.

Specifically, the third notification message is used to notify the OMC that the IPv6 terminal has acquired a new unicast IPv6 address, and instructs the OMC to re-send the IPv6 anycast address in the network segment.

Step 59: The IPv6 terminal broadcasts the RA message, where "override" is not overwritten, indicating that the IPv6 anycast address is no longer occupied.

The IPv6 terminal may broadcast the RA message by sending the third notification message. Then, the IPv6 terminal can delete the anycast address configuration and no longer reply to the NS message related to the IPv6 anycast address. The router can delete the correspondence between the terminal and the anycast address after the aging time. The OMC resends the OM-ping^ message until the terminals in the subnet are registered.

In this embodiment, the public configuration information is obtained through the IPv6 anycast address, and the unicast IPv6 address is configured according to the IPv6 anycast address to perform the OMC registration. In this embodiment, the IPv6 anycast address is directly occupied by the unicast IPv6 address, which simplifies the process. .

FIG. 6 is a schematic structural diagram of a terminal network element according to a sixth embodiment of the present invention. The terminal network element may be a device that performs the foregoing terminal side method, and may be an IPv6 terminal, such as a base station.

For example, the packet sent by the OMC including the IPv6 anycast address and the common configuration information is The OM-ping packet is configured to send an NA message to the router after determining to use the IPv6 anycast address, and receive the OMC sent by the router after receiving the NA message. The packet includes the IPv6 anycast address and the public configuration information, and obtains the public configuration information from the packet that is sent by the OMC and includes the IPv6 anycast address and the common configuration information.

In an embodiment, when the terminal network element directly transmits the message to the OMC, the first packet is a packet that is sent by the OMC and includes an IPv6 anycast address and a common configuration information, where the receiving module is specifically configured to receive the OMC. And the sending the packet that includes the IPv6 anycast address and the common configuration information. The obtaining module is specifically configured to obtain, after determining to use the IPv6 anycast address, the packet that is sent by the OMC and includes the IPv6 anycast address and the common configuration information. The public configuration information.

The above IPv6 anycast address can have the following format: Subnet segment of the subnet where the NE is located:: Specific EUI-64. This particular EUI-64 can be generated as follows:
