  • the port relay module will exchange RS/RA and DHCPv6 messages with the network to obtain the IPv6 address information assigned by the network and configure it into the address information block.
  • the air interface relay module also obtains information from the local air interface protocol stack, such as from the PDN.
  • the IPv6 interface identifier carried in the response message is configured into the address information block.
  • Step 2 After the TE initiates the dialing, the TE and the MT perform LCP and IPV6CP interaction.
  • the MT obtains the IPv6 interface identifier from the address information block and configures it to the TE; the TE uses the interface identifier to generate the local link address.
  • Step 3 RS/RA and DHCPv6 interaction between the TE and the MT to obtain global unicast IPv6 address and DNS information; at this time, the TE does not need to exchange data packets such as RS/RA with the network;
  • Step 4 If the TE initiates a network disconnection, only the PPP link between the TE and the MT is disconnected, and the air interface PDN is still activated.
  • Step 5 If the TE re-initiates networking, then after the LCP and IPV6CP interaction is completed, it will start to interact with the network to perform RS, RA, and DHCPv6. However, the actual interaction module of the MT is actually interacting with it. The message initiated by the TE to the network side terminates in this module, and the module is transparent to the TE. It is precisely because the subsequent re-networking process no longer occurs between the terminal and the network, the establishment of the link becomes fast, the network signaling resources are saved, and the network load is reduced. This is what this program means.

  • Step S901 The MT is powered on, and initiates an attach request (Attach Request), where the request includes a PDP Type such as “IPv6”, “IPv4v6”;
  • Step S902 The MME sends a message to the core network gateway to request to establish a default bearer.
  • Step S903 The P-GW requests information such as an IPv6 address from the DHCP server of the external PDN through the DHCPv6 mechanism.
  • Step S904 Create a session response, and the default bearer is successfully established.
  • Step S905 Attach succeeds
  • Step S906 The air interface relay module sends a Router Solicitation (RS) message to the network to trigger the network to immediately send a Router Advertisement (RA) message.
  • RS Router Solicitation
  • RA Router Advertisement
  • Step S907 After receiving the RA message, the air interface relay module performs DHCPv6 interaction with the network side (may be a stateful DHCPv6 process, and may also be a stateless DHCPv6 process). Specifically, it is determined by the parameters M-flag and O-flag carried in the RA message.
  • Step S908 The DHCPv6 process is performed between the air interface relay module and the network side.

  • the interface identifier is allocated to the TE through the IPv6CP in step S1003, and the TE uses it to generate the local link.
  • steps S1004 and S1005 are RS/RA procedures performed by the TE with a link-local address (wherein the RS process corresponds to step S1004, the RA process corresponds to step S1005), and the local relay module needs to communicate with the address information module to obtain Information about the address configuration method, as well as address information.
  • the process is an interaction process with the core network. In this case, it is transparently replaced by the relay agent module of the MT.
  • the RA message of S1005 is that the RA packet sent by the original P-GW is copied, and the M-flag, O-flag is included, and the RA may also carry an IPv6 address prefix. According to the values of M and O, there are two common cases.
  • S1006 should initiate a DHCPv6 request. That is, the TE obtains all information including IPv6 and DNS addresses through the DHCPv6 process. If the O is 1, the S1005's RA will contain the IPv6 address prefix. The TE uses the IPv6 address prefix to generate the global IPv6 address.

Le procédé comprend les étapes suivantes : un terminal mobile obtient des informations d'adresses IPv6 et des informations DNS (informations de serveur de nom de domaine) assignées par un réseau ; le terminal mobile envoie, lorsqu'un dispositif hôte est connecté au réseau au moyen du terminal mobile, les informations d'adresse IPv6 et les informations DNS au dispositif hôte, les informations d'adresse IPv6 et les informations DNS étant utilisées par le dispositif hôte pour accéder au réseau. La présente invention résout les problèmes dans l'état de la technique d'une forte charge côté réseau et d'un long temps de connexion au réseau d'un côté dispositif hôte, causés par de multiples interactions entre le dispositif hôte et le réseau durant des opérations de connexion au réseau après que le dispositif hôte s'est déconnecté à maintes reprises du réseau, accomplissant de cette façon l'effet de réduire la charge côté réseau et le temps de connexion au réseau du dispositif hôte.
