Embodiment 1

[0041] The embodiment of the present invention provides a method for IPv6 address allocation, such as figure 1 As shown, the method includes:

[0042] Step 101: Receive a request message for assigning an address to a user equipment UE, where the request message includes an identifier of the network domain where the UE is located;

[0043] Step 102: Determine whether an IPv6 prefix corresponding to the identifier of the network domain where the UE is located is stored;

[0044] Step 103: When the IPv6 prefix corresponding to the identifier of the network domain where the UE is located is stored, send to the UE the IPv6 prefix corresponding to the identifier of the network domain where the UE is located;

[0045] Step 104: When the IPv6 prefix corresponding to the identifier of the network domain where the UE is located is not saved, assign an IPv6 prefix to the UE, send the IPv6 prefix to the UE, and save the location where the UE is located. The corresponding relationship between the ...

Embodiment 2

[0062] The embodiment of the present invention provides a method for IPv6 address allocation. The executor of the method is a device that processes address allocation, and specifically may be a packet data gateway. The packet data gateway may be a PDN-GW (Packet Data Network Gateway, packet data gateway). ), it can also be S-GW (ServingGateway) in PMIP (ProxyMobileIP) scenarios, such as Figure 5 As shown, the method includes:

[0063] Step 501: Receive a request message for assigning an address to a user equipment UE, where the request message includes an identifier of the network domain where the UE is located;

[0064] Specifically, after receiving the attach request message sent by the UE, the MME sends a session creation request message to the PDN-GW, where the attach request message includes the identifier of the network domain where the UE is located, and The PDN-GW receives the session creation request message sent by the MME through the S-GW.

[0065] The MME is a mobility ...

Embodiment 3

[0150] The embodiment of the present invention provides a method for IPv6 address allocation. The executor of the method is a device that processes address allocation, and specifically may be a packet data gateway. The packet data gateway may be a PDN-GW, which is also a PMIP scenario. Can be S-GW, such as Picture 10 As shown, the method includes:

[0151] Step 1001: The device that handles address allocation negotiates with the Dynamic Host Configuration Protocol DHCPv6 server whether to support the ability of the DHCPv6 server to allocate global IPv6 addresses;

[0152] The device for processing address allocation is a packet data gateway, and the packet data gateway is specifically a PDN-GW, and may also be an S-GW in a PMIP scenario.

[0153] Specifically, if the DHCPv6 server supports the ability of the DHCPv6 server to allocate a global IPv6 address, the following procedure is executed, and if the DHCPv6 server does not support the ability of the DHCPv6 server to allocate a gl...

Abstract

The invention discloses a method and equipment for assigning an IPv6 address, relating to the field of communication technology, which can assign the same IPv6 prefix to different UEs in the same network domain, and increase the available space of the IPv6 address. In the embodiment of the present invention, the UE sends an address allocation request message to the address allocation device, the request message includes the identifier of the network domain where the user equipment UE is located, and then receives the sixth-generation address allocation message sent by the address allocation device. Internet Protocol IPv6 prefixes, and generate a global IPv6 address based on the IPv6 prefixes. The solutions provided by the embodiments of the present invention are suitable for use in address allocation.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for IPv6 address allocation. Background technique [0002] With the advent of the mobile broadband era, users need to use broadband access services anytime and anywhere, so EPS (EvolvedPacketSystem, evolved packet system) appears, wherein the core part of the EPS is EPC (EvolvedPacketCore, evolved packet core). The EPC now uses an all-IP (Internet Protocol, Internet Protocol) flat architecture, so when UE (User Equipment) needs to establish a PDN (Packet Data Network) connection, it first needs to obtain an available IP address and use it The IP address is used to communicate with external networks. Therefore, address allocation is a necessary step for the UE to create a PDN connection. With the evolution of IPv4 (Internet Protocol Version 4, the fourth generation of Internet Protocol) to IPv6, the allocation of IPv6 addresses has become more an...
