Description
Technical field
The mobile network technology that the present invention relates to divide into groups relates to routing optimization method and device in a kind of mobile network that divides into groups concretely.
Background technology
Along with the tide of global ipization grows in intensity, increasing communication system adopts IP as intrasystem host-host protocol in standard.At moving communicating field,, need a kind of mechanism of enhancing to finish the mobile management of carrying based on IP because terminal need be changed the on-position flexibly.Under this trend, the IETF of internet engineering task group organizes and has proposed mobile IP notion at first and carried out 10 years of researches, nowadays mobile internet protocol edition 4 (MIPv4), mobile internet protocol edition 6 (MIPv6) all formally becomes the standard of IETF and is adopted by various mobile communication standard tissues.Simultaneously, various enhancement techniques at aspects such as MIP switching, safety, performances also emerge in an endless stream at present, and this wherein just comprises the proxy-mobile IP technology.Its main thought does not promptly need terminal to support mobile IP, and user's IP address and the IP address of oneself are carried out the similar binding registration operation with MIP to mobile home agent in this locality (LMHA) or home agent (HA) by access gateway AG W, make between the different IADs (AGW) of portable terminal in same local HA (LMHA) or HA service range when mobile that the IP packet can be correct is routed to portable terminal.This to mobile IP technology improvement and strengthen the requirement of having simplified greatly terminal, also reduce simultaneously terminal to a great extent and given network, the especially burden that part causes of eating dishes without rice or wine in registration, when switching, improve resource utilization, also brought the customer location beneficial effect of aspect such as maintain secrecy.In addition, because the network size that the proxy-mobile IP technology can realize is subject to certain restrictions, the network configuration of while applying MIP and proxy-mobile IP appears probably also in the future mobile communications net.
According to existing standard criterion, (or realize the equipment or the entity of similar IP access function when two at same access gateway AG W, as in CDMA HRPD (high rate packet data) HRPD system, being packet data serving node PDSN, it in the CDMA evolvement network control access point (CAP) etc., might as well all be called IP access function entity at this) service mobile node (all moving the simple IP protocol stack) down is when communicating by the proxy-mobile IP technology, and routed path that its IP wraps and source, destination address are as shown in Figure 1.The routed path of its packet is: MN-〉AGW-〉LMHA-〉AGW-〉CN, in the other direction, the routed path of its packet is identical, and direction is opposite.
Perhaps (or realize the equipment or the entity of similar IP access function at same access gateway AG W when two, as in CDMA HRPD system, being PDSN, being CAP etc. in the CDMA evolvement network) (MN moves the MIPv4 protocol stack to service mobile node down, CN operation MIPv4 or simple IP protocol stack) when communicating, its IP packet routed path from CN to MN is: CN-〉AGW-〉HA-〉AGW-〉MN, if MN enables the reverse tunnel function, then the routed path from MN to CN is identical, and direction is opposite.
Perhaps (or realize the equipment or the entity of similar IP access function at same access gateway AG W when two, as in CDMA HRPD system, being PDSN, in the CDMA evolvement network for CAP etc.) when mobile node (all moving the MIPv6 protocol stack) under the service communicates by the proxy-mobile IP technology simultaneously, its IP packet routed path from CN to MN is: CN-〉AGW-〉LMHA-〉HA-〉LMHA-〉AGW-〉MN, as the same in the other direction.Even enabled the MIPv6 route optimization mechanism among the MIPv6, its routed path still exists circuitous, and concrete routed path is: MN-〉AGW-〉LMHA-〉AGW-〉CN, in the other direction, the routed path of its packet is identical, and direction is opposite.
Perhaps (or realize the equipment or the entity of similar IP access function at same access gateway AG W when two, as in CDMA HRPD system, being PDSN, being CAP etc. in the CDMA evolvement network) (MN moves the MIPv4 protocol stack to service mobile node down, CN operation MIPv4 or simple IP protocol stack) when communicating by the proxy-mobile IP technology simultaneously, its IP packet routed path from MN to CN is: MN-〉AGW-〉LMHA-〉AGW-〉CN, for in the other direction, the routed path of its packet is identical, and direction is opposite.
From as seen above-mentioned, exist serious route circuitous in the prior art, increased a large amount of unnecessary core network data flow and time delays, and much data when transmitting, core net also need to use the tunnel transmission, have further increased network burden and time delay.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, specific embodiments of the invention are elaborated below in conjunction with accompanying drawing.
The generation of alternate route is entangled its reason and is because the IP address that mobile node uses and the IP address of host configuration its actual physical topology position of direct reflection in fixed network.Therefore, even Correspondent Node is close at hand, the IP packet must be followed the protocol requirement of mobile IP or proxy-mobile IP, and route returns HA or LMHA transmits again.
The present invention promptly provides a kind of like this method, since when using the proxy-mobile IP technology at access gateway AG W (to MIPv4, also play the part of FA role simultaneously) the last existing IP address information that it descends all-access user to register, when AGW receives the IP bag that portable terminal sends, at first the calling party tabulation with the destination address in the IP packet header and its preservation compares, if the IP address of coupling is arranged, be that Correspondent Node also uses identical AGW access mobile core net, then AGW does not continue the MIP or the proxy mobile IP protocol of standard, encapsulation IP bag is delivered to LMHA or HA by the tunnel, but directly the IP packet is forwarded to Correspondent Node.
Introduce the technical program below in conjunction with specific embodiment.
Embodiment 1
Fig. 2 is the routing optimality flow chart of the embodiment of the invention 1.Suppose that portable terminal A is MIP or simple IP terminal, and AGW (be equally applicable to PDSN or CAP etc. other IP access function entity) may move the proxy-mobile IP function, Correspondent Node B may be the MIP terminal, also may be the simple IP terminal.Portable terminal A sends the IP packet by eating dishes without rice or wine to Correspondent Node B, and packet at first arrives access gateway AG W, and the handling process of AGW comprises the steps: as shown in Figure 2
After a.AGW receives the IP packet that terminal A sends, inquire about the access list of self, judge whether that the IP address of registered terminal and the destination address in the IP packet header are complementary.
If b. there is occurrence, promptly Correspondent Node also is to use identical AGW (or PDSN, or CAP etc.) access mobile core net, then directly transmits packet to Correspondent Node;
If c. do not find occurrence, be that Correspondent Node is not to use this AGW (or PDSN, or CAP etc.) mobile core network that inserts then uses the tunnel that the IP bag is sent to HA or LMHA node according to MIPv4 external agent (FA) or proxy mobile IP protocol predetermined process mode.
Wherein the access list of AGW inquiry can be self existing access list during as FA or mobile IP agent, also can be the new table that regenerates according to existing access list, and according to the information real-time update of source table.This tabulation all has a record at the portable terminal in each its service range, local ip address (being its Care-of Address CoA that in this zone, uses), link layer address, the lifetime information that must comprise the simple IP terminal for the MIP terminal, the IP address and the information such as link layer address, dhcp server ip address thereof that also may comprise the network access Identifier NAI, HoA address (the MIP terminal is peculiar) of portable terminal, the mobile anchor point IP address of using (, or realizing the entity of similar local HA function) as the LMHA of registration.
Utilize routing optimization method of the present invention, four kinds of scenes in the then corresponding existing scheme, (or realize the equipment or the entity of similar IP access function when two at same access gateway AG W, as in CDMA HRPD system, being PDSN, in the CDMA evolvement network for CAP etc.) mobile node (all moving the simple IP protocol stack) under the service is when communicating by the proxy-mobile IP technology, the routed path of its packet is: MN-〉AGW-〉CN, for in the other direction, the routed path of its packet is identical, and direction is opposite.
Perhaps (or realize the equipment or the entity of similar IP access function at same access gateway AG W when two, as in CDMA HRPD system, being PDSN, be CAP etc. in the CDMA evolvement network) the following mobile node of service (MN operation MIPv4 protocol stack, CN operation MIPv4 or simple IP protocol stack) when communicating, its IP packet routed path from CN to MN is: CN-〉AGW-〉MN, if and MN enables reverse tunnel function (RFC 3024), then the routed path from MN to CN can be optimized for equally: MN-〉AGW-〉CN.
Perhaps (or realize the equipment or the entity of similar IP access function at same access gateway AG W when two, as in CDMA HRPD system, being PDSN, in the CDMA evolvement network for CAP etc.) mobile node under the service (all move the MIPv6 protocol stack and enabled route optimization mechanism among the MIPv6 (RFC3775)) is when communicating by the proxy-mobile IP technology simultaneously, its routed path is: MN-〉AGW-〉CN, for in the other direction, the routed path of its packet is identical, and direction is opposite.
Perhaps (or realize the equipment or the entity of similar IP access function at same access gateway AG W when two, as in CDMA HRPD system, being PDSN, being CAP etc. in the CDMA evolvement network) (MN moves the MIPv4 protocol stack to service mobile node down, CN operation MIPv4 or simple IP protocol stack) when communicating by the proxy-mobile IP technology simultaneously, its IP packet routed path from MN to CN is: MN-〉AGW-〉CN, for in the other direction, the routed path of its packet is identical, and direction is opposite.
By routing optimization method of the present invention, can eliminate mobile node at the circuitous and resource occupation of route unnecessary when belonging to a Correspondent Node under the IAD together and communicate by letter, reduce the possibility of time delay and packet loss, and improve the utilance of network transmission resource and the performance of delay sensitive business.
Embodiment 2
Because terminal data service also comprises the non-end-to-end application of a lot of visit Internet, various application servers etc., for these IP traffic amounts, AGW can pass through a pre-configured IP address range table, mask the search operaqtion that the IP packet of destination address in the non-moving terminal scope of application carried out in advance, handle operation and directly carry out normal FA or proxy-mobile IP to access list.This improvement can reduce some unnecessary AGW search operaqtions, alleviates the burden that AGW handles IP bag, especially when terminal to the flowing of access of various application servers and network-external greatly the time, its meaning is more obvious.The concrete handling process of AGW is as shown in Figure 3:
(1), but judges that destination address is whether in optimization range according to pre-configured IP address range table.
Wherein, pre-configured IP address range can be one section or several sections IP address field that allows to carry out routing optimality, also can be for not allowing to carry out the IP address range of routing optimality.For example, when pre-configured IP address field is when allowing to carry out the IP address field of routing optimality, when the IP packet received from wireless access network RAN, at first relatively whether destination address is in this pre-configured IP address range, if then continue to carry out route optimization process; Handle operation if not then carrying out normal FA or proxy-mobile IP.And when pre-configured IP address field when not allowing to carry out the IP address field of routing optimality, but the destination address of the IP of reception bag illustrates that then this destination address is in optimization range not in pre-configured IP address range the time.
(2) if judged result for not, then uses the tunnel that the IP bag is sent to HA or LMHA node according to MIPv4 external agent (FA) or proxy mobile IP protocol predetermined process mode.
(3) if judged result for being, then further, is searched for the access list of IAD self, judge whether that the IP address of registered terminal and the destination address in the IP packet header are complementary.
(4), then directly transmit packet to Correspondent Node if there is occurrence;
(5), then use the tunnel that the IP bag is sent to HA or LMHA node according to MIPv4 external agent (FA) or proxy mobile IP protocol predetermined process mode if do not find occurrence.
In as above each embodiment, for the MIPv6 terminal, AGW can be when core net be given terminal distribution HoA, and perhaps terminal carries out learning the HoA address that terminal is used in the operating process such as neighbours find, the repeat to address (RA) is checked, transmission packet, and this information is joined in the access list of oneself.Be IP when bag of portable terminal HoA when AGW receives destination address like this, can judge this portable terminal also in the service range of oneself by the access list of retrieving oneself, thereby directly transmit this packet.
For example in the prior art, the simple IP terminal under the same AGW is wrapped source, destination address as shown in Figure 4 to routed path and the IP that the mobile IP v 6 terminal sends packet, is CN-〉AGW-〉HA-〉AGW-〉MN.
When receiving CN, AGW sends IP when bag that destination address is the HoA of MN, AGW retrieves its access list, retrieve and use the terminal of this HoA address current just in time also in the coverage of oneself, then AGW uses the link-layer identification of MN directly to transmit this packet to MN, routed path after it is optimized is CN-as shown in Figure 5〉AGW-〉MN.
Equally, the simple IP terminal under same AGW sends packet to the mobile IP v 6 terminal, and IP bag routed path when AGW realizes the proxy-mobile IP function simultaneously and IP bag source, destination address are CN-as shown in Figure 6〉AGW-〉HA-〉AGW-〉MN.
When receiving CN, AGW sends IP when bag that destination address is the HoA of MN, AGW retrieves its access list, retrieve and use the terminal of this HoA address current just in time also in the coverage of oneself, then AGW uses the link-layer identification of MN directly to transmit this packet to MN, routed path after it is optimized is illustrated in figure 7 as CN-〉AGW-〉HA-〉AGW-〉MN.
Method of the present invention can realize that it can comprise by the routing optimality device of the mobile network that is used to divide into groups:
The memory cell that is used for the memory access user list;
IP inserts entity, is used to receive the IP bag that mobile node sends, and retrieves described calling party tabulation, in described tabulation, exist with described IP bag in destination address be complementary the IP address time, directly transmit described IP packet to destination.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.Within the spirit and principles in the present invention all, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
