Based on above-mentioned analysis, in the present embodiment, optimize on handoff functionality basis at 3GPP2 and 3GPP protocol definition, by what realize the improvement optimizing handoff procedure.Comprise two kinds of thinkings, a kind of is, by other network elements, the IPv6 prefix of UE is carried to HSGW110; Another is exactly adopt the method substituted, and does not namely use global I Pv6 address when recovery IPv6 dedicated bearing, uses link-local address.All effectively can solve defect existing in correlation technique by any one of above-mentioned thinking: namely overcome time the UE106 existed in prior art switches from LTE to eHRPD network optimization and cannot recover IPv6 dedicated bearing, thus the service quality of the data service after optimizing switching cannot be ensured.
Relate to three embodiments below based on above-mentioned two kinds of thinkings are described.
Embodiment 1, if UE106 has applied for IPv6 service under LTE, then in the process of pre-registration, UE106 increases the prefix field carrying IPv6 in VSNCPconfigrequest message.Originally agreement has required to carry IPv6 interface ID area, has had IPv6 prefix and IPv6 interface ID, just can construct the IPv6 address that the overall situation is complete.Complete IPv6 address just may be used for the TFTIPv6IE head that HSGW110 sends to UE106.
Embodiment 2, in the process of pre-registration, carries the IPv6 address of UE to HSGW110 by PCRF102.HSGW110 obtains UE106 global I Pv6 address with this, just can fill in correct IPv6 address in the TFTIPv6IE head sending to UE106; HSGW110 correctly can send RSVP message to UE106, thus can recover IPv6 dedicated bearing.

In step 1605, if UE106 has applied for IPv6 service under LTE, then UE106 will obtain IPv6 prefix from the network of LTE.In VSNCP configuration request message, UE106 carries the prefix of IPv6 to HSGW110.HSGW110 preserves the IPv6 prefix that UE106 carries.For this reason, need the protocol interface of the VSNCP configuring request revised between HSGW110 and UE106, allow to carry IPv6 prefix in VSNCP configuration request message.
Preferably, carry IPv6 prefix in this VSNCP configuration request message can implement as follows: amendment PDNAddress field (is specifically shown in 3GPP2X.S0057-Bv1.09.1.4.1, original encoding form cannot carry IPv6 prefix), regulation PDNAddress field adopts TS29.274, the coded system of the PDNAddressAllocation field (PDNAddressAllocation field can carry IPv6 prefix) that 8.14 chapters and sections describe.
Preferably, carrying IPv6 prefix in this VSNCP configuration request message can also implement as follows: the definition not changing original field in VSNCP configuration request message, but a newly-increased field, this field can carry IPv6 prefix.New field can be: option names is UEIPv6Prefx, and option type is 23, and option coded format adopts TS29.274, the coded system of the PDNAddressAllocation field that 8.14 chapters and sections describe.
In step 1613, time HSGW110 sends out Resv message to UE106, the IPv6 prefix that the UEIPv6address301 field in TFTIPv6IE uses HSGW110 to preserve.
Preferred embodiment 2
figure17 is the flow processs of pre-registration when switching from long-term evolving network to the optimization of evolved high speed packet data network according to the mobile terminal of the preferred embodiment of the present invention 2
figure, as
figureshown in 17, this flow process, except comprising relevant identical flow process, comprises as follows to the step of special processing wherein:
When pre-registration, the IPv6 prefix of UE is brought HSGW110 by PCRF102.According to correlation technique, time UE106 is linked under LTE, PCRF102 can obtain the IPv6 prefix of UE from PDNGateway105 network element by Gx interface.The IPv6 prefix of UE can be carried to HSGW110 by Gx interface by Gxx interface by PCRF102.HSGW preserves the IPv6 prefix of UE.
Preferably, in step 1707, the IPv6 prefix of UE is brought HSGW110 and is setting up the IPv6 prefix field increasing UE in gateway control session response message by PCRF102.PCRF102 is setting up in gateway control session response message, carries the IPv6 prefix of UE to HSGW110.
Preferably, the IPv6 prefix of this UE can adopt Framed-IPv6-Prefix (see RFC40056.11.6 chapters and sections) field to realize.
Preferably, in step 1711, it can also be that PCRF102 issues in request message in gateway control and Qos rule the IPv6 prefix field increasing UE that the IPv6 prefix of UE is brought HSGW110 by PCRF102.PCRF102 issues in request message in gateway control and Qos rule, carries the IPv6 prefix of UE to HSGW110.
Preferably, the IPv6 prefix of this UE can adopt Framed-IPv6-Prefix (see RFC40056.11.6 chapters and sections) field to realize.
In step 1713, time HSGW110 sends out Resv message to UE106, the UEIPv6 prefix that the UEIPv6address301 field in TFTIPv6IE uses HSGW110 to preserve.
Preferred embodiment 3
figure18 is the flow processs of pre-registration when switching from long-term evolving network to the optimization of evolved high speed packet data network according to the mobile terminal of the preferred embodiment of the present invention 3
figure, as
figureshown in 18, this flow process, except comprising relevant identical flow process, comprises as follows to the step of special processing wherein:
In step 1813, the UEIPv6Address field of HSGW110 in RESV message in TFTIPv6IE head uses the IPv6 link local address of UE, instead of original global I Pv6 address.By this amendment, HSGW110 no longer needs the global I Pv6 prefix of UE106 in the RSVP message setting up IPv6 dedicated bearing, thus has evaded the defect of agreement.
According to 3GPPTS23.401V10.2.15.3.1 chapters and sections and 3GPPTS23.402V10.1.04.7 chapters and sections, PDNGateway105 is responsible for UE106 distributing IP v6 prefix.When optimization switches pre-registration, the IPv6 interface ID of oneself is brought HSGW110 by UE106 in VSNCP configuration request message (see step 205).PDNGateway105 is when giving UE106 distributing IP v6 interface ID in the present embodiment requirement, same UE106, and the different PDN under same APN connect and distribute different IPv6 interface ID.
Preferably, this same UE, different PDN under same APN connect the method for distributing different IPv6 interface ID: choose 4 bits (such as at the IPv6 interface ID of 64 bits, bit 11 to 14), these 4 bits are used for same UE106, the counting that the different PDN under same APN connect, first PDN connects use value 0, second PDN connects use value the 1, three PDN and connects use value 2, by that analogy.
Increasing this reason required is: at same UE, when supporting that multiple PDN connects under same APN, determines that the PDN that RSVP message belongs to connects according to the IPv6 prefix of UE.When the UEIPv6Address field in TFTIPv6IE head uses the IPv6 link local address of UE, in RSVP message, lack the IPv6 prefix information of UE.The PDN that RSVP message belongs to connects to need the IPv6 interface ID by UE to determine.So require at same UE, the IPv6 interface ID that under same APN, multiple PDN connects is different.By the mark+PDNID+IPv6 interface ID of UE, HSGW110 uniquely determines that a PDN connects.
