Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of Internet Protocol (IP, Internet Protocol) address distribution method and device.
Background technology
In 3G network, packet data protocol (Packet Data Protocol, PDP) address is used for providing service for subscriber equipment (User Equipment, UE) correctly carries out Packet data service.GGSN is user equipment allocation pdp address by pdp context activation.Pdp address generally adopts IP address format, and therefore IP address mentioned in this article is also pdp address.
An existing terminal can have a single carrier data card also can bundle multiple independently single carrier data cards (i.e. multiple UE chip) simultaneously.The terminal type having a single carrier data card is ordinary terminal, binding simultaneously has the terminal type of multiple independently single carrier data cards to be multiple users, for multiple users (Multiple User Equipment, MUE) the every data cards of the terminal of type or each UE chip use independently user's Services Identity Module (User Services Identity Module, USIM).On eating dishes without rice or wine, the data flow of every data cards is dispensed on different HSPA carrier waves, thus enables the terminal of MUE type exclusively enjoy the uplink and downlink bandwidth of many UE, realizes data throughout multiplication.
IP address assignment comprises STATIC IP ADDRESSING and dynamic IP addressing is distributed.Apply existing IP address assignment technology, no matter static mode or dynamical fashion, each UE in the terminal of MUE type can obtain different IP addresses, needs thus to carry out replacement process to the IP address in grouped data packet header.
Particularly, for upstream data, the terminal of MUE type needs data application layer issued to be divided into multichannel and is carried on different UE links, and the data on different UEs link merge by radio network controller (RNC); For downlink data, RNC needs Data dissemination application issued to different UE links, and the data on different UEs link merge by the terminal of MUE type.During specific implementation, RNC needs the terminal class determining that active user belongs to when active user accesses, namely determine that whether terminal class that active user belongs to be the terminal of MUE type, if, determine the terminal that active user belongs to, then will belong to one of them user of described terminal as primary user, other users as auxiliary user, and safeguard the binding relationship of multiple UE.RNC is respectively primary user and each auxiliary user sets up GPRS Tunnel Protocol user face (GPRS Tunnelling Protocol User Plane, GTPU), the service surface processing entities such as PDCP (PacketData Convergence Protocol, PDCP), RLC, MAC.Wherein, the GTPU entity acts of primary user is only had.Meanwhile, the signaling being independently initiated to core net due to UE multiple in MUE terminal connects, and therefore, each UE in the terminal of MUE type can obtain an IP address distributed by network side.
See Fig. 1, be uplink user data stream processing procedure, be tied to example explanation with UE0 and UE1.Suppose that UE0 is primary user, UE1 is auxiliary user.UE0 and UE1, respectively by the signalling interactive process with core net, obtains IP address ip 0 and the IP1 of network side distribution.The data received from PDCP0 and PDCP1 merge by RNC, and send on GTPU0 example passage.Wherein, PDCP1 needs to replace with IP0 to the source IP address in the IP packet header be forwarded in the data of PDCP0 by IP1.
See Fig. 2, be down user data stream processing procedure, RNC divides the data that GTPU0 receives, and shares on the PDCP example of UE0 and UE1.Wherein, PDCP1 needs to replace with IP1 to the object IP address in the IP packet header in the data of PDCP0 distribution by IP0.
From the technical scheme described in Fig. 1 and Fig. 2, for the source IP address in the IP packet header in the upstream data of auxiliary user, RNC needs to carry out the replacement of auxiliary user to primary user IP address; For the object IP address in the IP packet header in the downlink data of auxiliary user, RNC needs to carry out the replacement of primary user to auxiliary IP address.
Therefore, there is following problem:
1, RNC is to the replacement of IP address, increases Business Processing time delay, affects user's impression, and increases RNC Business Processing load, reduces RNC performance.
2, in the terminal for MUE type, each UE can distributing IP address, causes the network side IP address wasting of resources.
Especially when the data card that the terminal of MUE type bundlees or UE core number more time, and during the extensive popularization and application of the terminal of MUE type, the problems referred to above will become more and more serious.
Therefore, prior art, for the distribution method of the IP address of the terminal use of MUE type, increases Business Processing time delay, increases the processing load of RNC, waste IP address resource.

The embodiment of the present invention provides a kind of IP address assignment method and device, in order to reduce existing for belong to MUE type terminals user's distributing IP address time the processing load of service surface, and shorten Business Processing time delay.
In the present invention, IP address assignment is actually the distribution of pdp address, and because pdp address generally adopts IP address format, therefore, pdp address distributes the IP address assignment of general indication user, all refers to the distribution of IP address in the present invention.
The embodiment of the present invention, for the situation (namely multi-user binding is in the situation of same terminal) of MUE type terminals, proposes a kind of mobile subscriber's IP address assignment method of improvement.Use the method, each user UE bundled in arbitrary MUE type terminals can be made to use identical IP address.Particularly, for the static address method of salary distribution, increase the consideration of MUE type terminals, namely belong to each user of same MUE in HLR, use identical static ip address.For dynamic address allocation mode, increase the consideration of MUE type terminals, the terminal that GGSN belongs to according to the user (hereinafter referred to as active user) of request access network is MUE type terminals or ordinary terminal, is active user's distributing IP address.If the terminal type of active user's ownership is MUE type, be then that the user belonging to same terminal with active user distributes the IP address identical with active user.If the terminal type of active user's ownership is ordinary terminal, then conventionally, be active user's distributing IP address.The present invention is by distributing identical IP address for the multiple users (at least two users) belonging to same terminal, eliminate existing for belong to MUE type terminal distribution IP address time the processing load of service surface, shorten Business Processing time delay, save network side IP address resource simultaneously.
It should be noted that, in fact the terminal in " belonging to multiple users of same terminal " of the present invention is exactly MUE type terminals, and therefore, this section in " belonging to multiple users of same terminal " cited below all refers to MUE type terminals.
The IP address assignment method that the embodiment of the present invention provides goes for the IP address distribution that 3G network belongs to MUE type terminals.
The technical scheme that the embodiment of the present invention provides is illustrated below by accompanying drawing.
First dynamic IP addressing assigning process is described, be set to a certain user's distributing IP address of MUE type terminals, this terminal bundlees 3 users simultaneously, is respectively UE1, UE2, and UE3.
See Fig. 3, the IP address assignment method that the embodiment of the present invention provides comprises:
S11, GGSN (Gateway GPRS Support Node, GGSN) GPRS serving GPRS support node (Serving GPRS Support Node is received, SGSN) establishment packet data protocol PDP Context request (the Create PDP Context Request) message sent, comprising the user ID that the user (referred to as active user) with current request access network is corresponding.
The terminal of described active user's ownership can be ordinary terminal (only comprising the terminal of a user), also can be MUE type terminals (simultaneously bundling the terminal of multiple user), as UE1, UE2, and any one in UE3.
Particularly, when a certain user of MUE type terminals or the user of ordinary terminal ask access network, send to SGSN and activate PDP Context request (Active PDP Context Request) message.After SGSN receives Active PDP Context Request, send Create PDP ContextRequest message to GGSN, this message comprises the user ID corresponding with described active user.GGSN receives the Create PDP Context Request message from SGSN, and this message comprises the described user ID corresponding with active user.
No matter be Generic End-User or MUE type terminals user, the user ID between user is different, and the user ID of each user is unique.
Preferably, described user ID can adopt international mobile subscriber identity (International MobileSubscriber Identity, IMSI).
According to described user ID, S12, GGSN judge whether the terminal type that active user belongs to belongs to multiple users MUE type, and determine the terminal that active user belongs to.
Particularly, GGSN judges whether the terminal corresponding with this user ID prestored in GGSN belongs to MUE type terminals.
Each terminal (no matter being ordinary terminal or MUE type terminals), to a device identification, can use international mobile equipment identification number (International Mobile Equipment Identity, IMEI) to represent.
The IMSI of each user that each MUE type terminals comprises is unique, and the IMSI of the user that each ordinary terminal is corresponding is also unique.IMEI corresponding to each terminal is also unique.The binding relationship of each MUE type terminals and multiple user, and the relation of each ordinary terminal and user is pre-configured in GGSN.
GGSN is according to the binding relationship of IMEI and the IMSI corresponding with active user, can determine whether terminal corresponding to active user is MUE type terminals, particularly, if terminal corresponding to active user has binding relationship with multiple user simultaneously, then the terminal that active user is corresponding is MUE type terminals.
Further, can determine according to the IMEI corresponding with active user the terminal that active user belongs to simultaneously.
When S13, GGSN judge that the type of the terminal that active user belongs to is MUE type, again judge whether for the user belonging to same terminal (this terminal is the terminal that active user that GGSN determines belongs to) with active user is assigned with Internet protocol IP address.
Such as, suppose that active user is for the UE1 distributing IP address in a certain MUE type terminals, GGSN judges whether for UE2 or UE3 of this terminal is assigned with the IP address of access network.
It should be noted that, if the user of first of MUE type terminals request access network has been assigned with IP address, then GGSN can preserve this IP address, so that other users of this MUE type terminals use this IP address when access network.
S14, when GGSN judges to be assigned with IP address as the user belonging to same terminal with active user, the IP address that GGSN inquiry distributes for the user belonging to same terminal with active user, determines that this IP address is the IP address of active user.
S15, GGSN by the IP address assignment of active user determined to the active user of request access network.
That is the IP address determined directly is sent to the active user of request access network by GGSN.
Particularly, the described IP address determined is carried to create in PDP Context response message and sends to SGSN by GGSN, and the IP address received is carried at and activates the active user that PDP Context accepts to send in message request access network by SGSN.
Preferably, SGSN terminates pdp context activation by Activate PDP Context Accept; And SGSN routing forwarding PDP Packet Data Unit (Packet DataUnit, PDU) between GGSN and user.
Preferably, the method also comprises: determining as behind the IP address that active user distributes, recording this IP address and recording the corresponding relation of this IP address and active user.To be that other users belonging to same terminal with active user distribute this IP address.
Preferably, when GGSN judges to belong to active user the unallocated IP address of other users of same terminal, GGSN, from for obtaining a current IP address be not assigned with user configured address pool, determines that this IP address is the IP address of the active user of request access network; And by the IP address assignment determined to active user.
Above-mentioned multiple users for belonging to same terminal are assigned with identical IP address, processing procedure is replaced in the IP address eliminating existing RNC service surface, reduce existing for belong to MUE type terminal distribution IP address time the processing load of service surface, and shorten Business Processing time delay.
Introduce static type IP address assignment method provided by the invention below.
See Fig. 4, a kind of STATIC IP ADDRESSING method that the embodiment of the present invention provides comprises:
S21, SGSN receive the activation PDP Context request message that active user sends;
S22, SGSN by the IP address assignment that prestores in the subscription data corresponding with active user to active user;
Wherein, the IP address prestored in subscription data corresponding to the user of same terminal is belonged to identical.
Preferably, the IP address assignment that prestores in the subscription data corresponding with active user to active user, is specially by SGSN:
The IP address prestored in the user contracting data corresponding with active user is accepted message by activation PDP Context and distributes to active user by SGSN.
The all users belonging to same terminal have identical IP address and determine when subscribing packet service, and be the special static address of user, static address mapping table as user contracting data persistence in hlr.
As can be seen here, the present invention is directed to the distribution of static ip address, for the multiple users belonging to same terminal distribute identical IP address, save network side IP address resource, improve the utilization rate of IP address.
It should be noted that no matter be that STATIC IP ADDRESSING or dynamic IP addressing are distributed, all distribute in pdp context activation.As shown in Figure 5 and Figure 6, the activation PDP Context request (Active PDP Context Request) that sends to SGSN of UE; SGSN sends to GGSN and creates PDP Context request (Create PDP Context Request); GGSN returns to SGSN and creates PDP Context response (Create PDP Context Response); SGSN returns to user and activates PDP Context acceptance (Active PDP Context Accept).
According to subscription data, STATIC IP ADDRESSING, when SGSN sends Create PDPContext Request message to GGSN, static ip address is filled in request message, this static ip address is carried in the Active PDP Context Accept message that SGSN sends to user, this static ip address is sent to MUE user, as shown in Figure 5.
If adopt dynamic IP addressing to distribute, then SGSN does not fill static ip address in Create PDP Context Request message, and static ip address is empty.When GGSN receives described Create PDP ContextRequest message, if carry IP address, thinking that this IP address is static ip address, then can not be user's monthly dynamics IP address; If IP address is empty in Create PDP Context Request message, then when sending Create PDP Context Response message to SGSN, dynamic IP addressing is carried in Create PDP Context Response message, this dynamic IP addressing is carried in the Active PDP ContextAccept message that SGSN sends to user, this dynamic IP addressing is sent to MUE user, as shown in Figure 6.
