Description
Technical field
The present invention relates to communication technical field, be specifically related to a kind of method for processing downlink data message and device of packet radio gateway equipment.
Background technology
At GPRS (GPRS, General Packet Radio Service)/universal mobile telecommunications system (UMTS, Universal Mobile Telecommunication System) in the packet data network, subscriber equipment (UE, User Equipment) by GPRS Tunnel Protocol (GTP, GPRSTunneling Protocol) tunnel accessing group data network.When the user sets up GTP tunnel, carry APN (APN, Access Point Name) user's request at first sends to Serving GPRS Support Node (SGSN, Service GPRS Support Node), SGSN is according to the APN in user's request, a plurality of Gateway GPRS Support Node (the GGSN that are being connected with self, Gateway GPRSSupport Node) selects a GGSN in, set up GTP tunnel with it, and on GGSN, preserve packet data protocol (PDP, the Packet Data Protocol) context comprise this IP address.When the GGSN of SGSN and selection sets up the tunnel failure, then reselect a GGSN, and attempt setting up with it GTP tunnel according to APN.
SGSN and GGSN set up after the GTP tunnel success, during the user capture packet data network, uplink data messages is sent to GGSN by GTP tunnel, GGSN is according to the routing iinformation in the uplink data messages, this uplink data messages is sent to the gateway device of purpose packet data network, by the Data-carrying network, this uplink data messages is sent to final purpose ground by the gateway device of purpose packet data network.Issue the downlink data message of UE for the purpose packet data network, the Data-carrying network will be given GGSN according to routing forwarding, issue corresponding UE by GGSN by GTP tunnel then.So just finished data exchange process one time.
When UE uses dynamic IP addressing, promptly during the UE accessing group data network, be this UE distribution dynamic IP addressing by GGSN or aaa server or Dynamic Host Configuration Protocol server.UE inserts on different GGSN, can be by planning, for the user distributes different IP addresses.That is to say that UE inserts on different GGSN, the IP address difference of its acquisition.In this case, for the Data-carrying network, the unique corresponding GGSN of IP address in the downlink data message, when therefore the user uses Packet data service at every turn, can not change for the IP address corresponding relation of the GGSN that IP address and user in user's the downlink data message insert, also just can not change for the route of user's downlink data message.So just can on the gateway device of Data-carrying network, preserve the GGSN routing iinformation corresponding with the IP address, make the gateway device of Data-carrying network after receiving downlink data message, just can be according to the routing iinformation of self preserving, this downlink data message is issued to corresponding GGSN, by GGSN downlink data message is sent to corresponding UE then.
When the signatory static ip address of UE use, promptly the user is to use signatory static ip address no matter at which GGSN insert.Therefore the variation of the Data-carrying network GGSN that need insert along with the user to user's route and changing is so that can be properly routed to the GGSN that the user inserts to user's downlink data message.But owing to do not change the effective scheme of Data-carrying network to user's route, therefore, use the user of signatory static ip address generally can only fix GGSN of access in the prior art, user's up-downgoing data message all passes through this fixing GGSN that inserts and transmits; If the GGSN that the user inserts is not the GGSN of this fixing access, the success rate that then will be properly routed to UE to the downlink data message of UE is very low.
Except that above described radio network gateway packet equipment GGSN, for other packet radio gateway equipment, group data service node (the PDSN in CDMA 2000 (CDMA2000) system for example, Packet Data Service Node), worldwide interoperability for microwave inserts (WiMAX, WorldwideInteroperability for Microwave Access) the access business network gateway (ASN-GW in the system, Access Service Network Gateway) and WLAN (wireless local area network) (WLAN, Wireless LocalArea Network) system is linked into the packet data gateway (PDG in the GPRS network, Packet DataGateway) etc., also there is same problem.

Embodiment
The packet radio gateway equipment that the embodiment of the invention provides is handled in the method for downlink data message, and packet radio gateway equipment receives user's downlink data message; According to the IP address of this downlink data message, judge whether this user inserts at self, be then this downlink data message to be sent to the user; Otherwise the associated gateway facility information table according to setting in advance is transmitted to relevant packet radio gateway equipment with this downlink data message.
Packet radio gateway equipment with the GPRS packet data network is GGSN below, and corresponding associated gateway facility information table is an example for relevant GGSN information table, and the technical scheme of the embodiment of the invention is elaborated.
Fig. 1 is the method for processing downlink data message flow chart of packet radio gateway equipment in the embodiment of the invention.Fig. 2 is the schematic diagram of packet radio gateway equipment converting downlink data message in the embodiment of the invention.In conjunction with Fig. 1 and Fig. 2, this method may further comprise the steps:
Step 100: set in advance one group of GGSN component devices pond, and the relevant GGSN information table of each GGSN in the set device pond.
In this step, the relevant GGSN information table of each GGSN comprises the IP address of relevant GGSN at least.For example GGSN A and GGSN B component devices pond then are provided with the IP address of GGSN B in the relevant GGSN information table on GGSN A, the IP address of GGSN A is set in the relevant GGSN information table on GGSN B.If the GGSN of component devices has three: GGSN A, GGSN B and GGSN C, the IP address of GGSN B then can be set in the relevant GGSN information table of GGSN A, the IP address of GGSN C is set in the relevant GGSN information table of GGSN B, and the IP address of GGSN A is set in the relevant GGSN information table of GGSN C.Can certainly the relevant GGSN information table of each GGSN be set alternate manner, can be combined into a circulation, be i.e. all GGSN in the set of the relevant GGSN information table traversal equipment pond among all GGSN as long as can guarantee the relevant GGSN information table of all GGSN.
Step 101: when the user inserted GGSN in this equipment pond, this GGSN write down this user's user profile in the user message table of self, for example, and user's IP address.
In this step, user message table can be the information table that includes only IP address, also can utilize the PDP Context of setting up when the user inserts GGSN in the prior art to form user message table.
Step 102: a GGSN in the equipment pond receives the downlink data message to the user.
Step 103: the user message table that this GGSN preserves according to self, judge whether oneself is the GGSN that this user inserts, be execution in step 104 then, otherwise execution in step 105.
In this step, GGSN at first obtains user's IP address from the downlink data message that receives, in the user message table of self preserving, search the record that whether has with this IP matching addresses then, be then to judge it self is the GGSN that this user inserts, if do not find the record of coupling, then judge it self is not the GGSN that this user inserted.
When the PDP Context that utilizes the user to insert the GGSN preservation is formed user message table, the GGSN that receives the downlink data message of giving the user can be according to the IP address in the downlink data message, and the user is kept at the PDP Context of self when inserting, and judges whether oneself is the GGSN that this user inserts.
Step 104: this GGSN sends to the user with downlink data message, and process ends, shown in thin black line among Fig. 2.
It is same as the prior art that the GGSN that the user inserted will send to user's process to user's downlink data message, do not repeat them here.
Step 105: this GGSN sends to relevant GGSN according to relevant GGSN information table with this downlink data message, shown in thick black line among Fig. 2, is begun to carry out from step 102 by this relevant GGSN then.
In this step, the relevant GGSN information table that this GGSN inquiry self is preserved sends to one of them GGSN with this downlink data message.
After relevant GGSN received the downlink data message of the GGSN transmission in the equipment pond, same execution in step 103 if judge when oneself being the GGSN that the user inserted of downlink data message correspondence, then was transmitted to this downlink data message corresponding user.
Further, for avoiding the downlink data message forwarding that between each GGSN in component devices pond, circulates, then can stipulate no longer to transmit by the data that the GGSN in the equipment pond forwards; Perhaps only allow downlink data message in the equipment pond, to transmit certain number of times.
For example, comprise in the equipment pond under the situation of two GGSN that GGSN if find it self is not the access GGSN of respective user, also no longer transmits this downlink data message after receiving the downlink data message of another GGSN forwarding.Certainly, under situation, also can use this scheme more than two GGSN.
Perhaps, intercommunication interface between each GGSN also can be set, when GGSN is transmitted to downlink data message other GGSN in the equipment pond, this downlink data message can be labeled as the message of transmitting through inner, if this GGSN interface internally receives this downlink data message again, find that this downlink data message is through self inner message of transmitting, and then no longer carries out inside and transmits.For example GGSN can add the device identification of self in inner converting downlink data message, IP address for example, when in finding the downlink data message that receives, comprising the device identification of self, judge that then this downlink data message is through self inner message of transmitting.
Perhaps can utilize the time-to-live (TTL, Time To Live) in the IP agreement to limit the conversion times of downlink data message in the equipment pond.Specifically, GGSN judge oneself be not the downlink data message respective user insert GGSN the time, ttl value is subtracted 1, judge then whether this value is 0, be end process then; Otherwise be transmitted to the relevant GGSN in the relevant GGSN information table.
In another embodiment of the present invention, can in GGSN relevant information table, preserve the IP address of the GGSN that user's IP address and respective user inserted.Specifically, when the user activates on GGSN A, GGSN A can be by the proprietary protocol between Routing Protocol or the GGSN, this user's IP address is sent to GGSN in the equipment pond, other GGSN with the IP address of the IP address that receives and the GGSN A that sends this IP address as a recorded and stored in the relevant GGSN information table of self.After making that other GGSN receives this user's downlink data message, can find the IP address of GGSN that this user inserts, thus the GGSN that downlink data message correctly is transmitted to this user and is inserted.
The above as can be known, the technical scheme in the embodiment of the invention is equally applicable to other packet radio gateway equipment, for example the PDSN in the CDMA2000 system, the ASN-GW in the WiMAX system and wlan system are linked into PDG in the GPRS network etc.
