In the EPS system, the user can adhere to/and PDN connects in the activation and obtains immediately the IPv4 address, also can postpone to distribute the address namely adhering to/activation obtains the IPv4 address by DHCP (Dynamic Host Configure Protocol is referred to as DHCP) mode after finishing.
When the PDN type of UE request is IPv4v6, postpone to distribute address and ticket PDN reporting address process, as shown in Figure 4:
Step S402:UE sends and adheres to request to MME, the evolved packet system session management that it carries (EPS Session Management, referred to as ESM) message container indicating PDN type is IPv4v6, protocol configuration option (Protocol Configuration Options is referred to as PCO) indication is by DHCPv4 distributing IP v4 address;
Step S404: carry out attaching process, until MME receives the renewal position response message of HSS;
Step S406:MME sends to Serving GW and creates conversation request message, and wherein carrying PDN type is IPv4v6, PCO;
Step S408:Serving GW sends to PDN GW and creates conversation request message, and wherein carrying PDN type is IPv4v6, PCO;
Step S410:PDN GW distributing IP v4 and IPv6 address send establishment conversational response message to Serving GW, and wherein carrying the PDNIPv4 address is full 0, and the IPv6 address;
Step S412:Serving GW sends to MME and creates conversational response message, and wherein carrying PDN IPv4 address is full 0, and the IPv6 address;
Step S414:MME sends to adhere to UE and accepts message, and PDN IPv4 address is full 0 in the ESM message container that it carries, and the IPv6 interface identifier;
Step S416:UE does not get access to PDN IPv4 address in attaching process;
Step S418: attaching process is complete;
Step S420:UE need to obtain the IPv4 address, sends DynamicHost by the user's face passage that establishes to PDN GW agreement (Dynamic Host Configuration Protocol is referred to as DHCP) discovery message is set;
Step S422:PDN GW sends DHCP to UE and gives information, and wherein carries PDN IPv4 address;
Step S424:UE sends the DHCP request message to PDN GW;
Step S426:PDN GW sends the DHCP response message to UE, wherein carries PDN IPv4 address;
Step S428:UE gets access to PDN IPv4 address by the DHCP mode;
Step S430:UE IPv4 address information changes, and PDN GW does not notify CGF UE to get access to the IPv4 address;
Step S432:UE discharges the IPv4 address;
Step S434:UE does not need to send message by the IPv4 address, and UE sends the DHCP release message to PDN GW;
Step S436:UE IPv4 address information changes, and PDN GW does not notify CGF UE to discharge the IPv4 address.
At present, in correlation technique, EPS has introduced and postpone to have distributed address function, and namely the user is adhering to or PDN connects in the activation, and indication is by DHCPv4 distributing IP v4 address, then core net with the IPv4 address strap of full 0 to UE, adhering to or PDN connects after activation finishes, the user obtains the IPv4 address because of service needed, and then UE is as DHCP Client, PDN GW is as DHCP Server, and the user obtains the IPv4 address by the DHCP mode.Carrying PDN type when user's activation request message is the two stack addresses of IPv4v6 application IPv4v6, and indication is by DHCPv4 distributing IP v4 address, like this user adhering to/PDN connects in the activation, UE does not get access to the IPv4 address, UE can obtain the IPv6 prefix by the automatic configuration of IPv6 stateless address and carry out business, adhere to/PDN connects any time UE after activating successfully and need to obtain the IPv4 address and carry out business, then can obtain UE IPv4 address by the DHCP mode, and follow-up any time UE no longer needs IPv4 address access service, then can discharge UE IPv4 address by the DHCP mode, connect life cycle at PDN like this, user's IPv4 address is to grow out of nothing, or from having to without like this changing.
As shown in Figure 4, when the PDN type of above-mentioned UE request is IPv4v6, postpone to distribute step S430 and step S436 in address and the ticket PDN reporting address process, UE IPv4 address information changes, and UE is not obtained the IPv4 address or discharges the IPv4 address information and notify to charging entity (as: CGF).In sum, off-line and online charging information do not embody the variation of PDN IPv4 address information in the correlation technique, and the traffic aided of user's address and user's access, during the user is online, its address change has reflected user's professional usage behavior, so this variation need to be embodied in the ticket.
