Background technique

Present inventor at least has found exist in the related technology during realizing the embodiment of the present application technical solution Following technical problem:

In 4G network, traditional CS domain network element has disappeared, and voice, data service are held using ps domain core net It carries.Ps domain core net in 4G network is also referred to as EPC core net, and main network elements include (1) eNodeB:eNodeB for being responsible for nothing Line resource management is integrated with the function of the part similar base station 2G/TD and base station controller；(2) MME:MME is the control under 4G access Veil member processed, for being responsible for mobile management function to ps domain；(3) S-GW: for user face Access Service Network Gateway, it is equivalent to traditional Gn The user plane functions of SGSN；(4) it P-GW: for borde gateway, is connect for providing carrying control, charging, address distribution and non-3 gpp The functions such as enter, is equivalent to traditional GGSN；(5) HSS: for user data management network element, the functions such as authenticate and contract for providing； (6) DNS: the network element address parsing for being responsible in the operation flows such as attachment, TAU.The network topology of EPC core net such as Fig. 1 institute Show.

In EPC core net, S-GW network element is a very important network element, plays a part of forming a connecting link, in radio layer It is interconnected with ENODEB, processes user data.It is interconnected in core stratum reticulare and P-GW network element, completes the routing and forwarding of data packet Function.

In the current 4G network technology used, MME equipment is to select S-GW network element by tracking area (TA) parameter , S-GW network element corresponding with the TA parameter is specifically selected according to the corresponding relationship of the TA parameter of storage and SGW.Its In, TA parameter is a new concept in 4G network, for identifying the location information of S-GW in 4G network.

One application scenarios is the terminal attachment flow of 4G network, which is that MME equipment is receiving terminal user After online request, need to find corresponding S-GW network element to establish the bearer path of data connection for the user, in Fig. 2 Shown in part represented by chain-dotted line, as selection S-GW and the process for establishing carrying.Process as shown in Figure 2, including following step It is rapid:

Step 102.eNodeB forwards Attach Request message to MME；

Step 103. interacts Authentication message between UE and MME；

Step 104a.MME sends Update Location message to HSS；

Step 104b.HSS sends Insert Subscriber Data message to MME；

Step 104c.MME returns to Insert Subscriber Data Ack message to HSS；

Step 104d.HSS returns to Update Location Ack message to MME；

Step 105.MME sends Create Default Bearer Request message to S-GW；

Step 106.S-GW sends Create Default Bearer Request message to P-GW；

Step 107. interacts PCRF interaction message between P-GW and PCRF；

Step 115.S-GW returns to Updata Bearer Response message to MME.

Which S-GW equipment is MME equipment select to carry out service for it completed by the S11 interface of MME and S-GW. Simultaneously in the selection process, an important network element DNS is also used.The pass corresponding with S-GW equipment TA is stored on DNS It is as follows to prepare data for system:

Wherein TA data are stored with the format of tac-lb03.tac-hb25, the low byte that the part lb is TA, the part hb For the high byte of TA；S-GW information is indicated with italic highlight mark；

S-GW data are with S-GW-pool-3.sy.ln.node.epc.mnc000.mcc460.3gppnetwork.org's Format storage, S-GW-pool-3.sy.ln.node.epc are S-GW nodename, It mnc000.mcc460.3gppnetwork.org. is mobile standard identifier；

It is the data of TA with the information of runic highlight mark, is respectively indicated with high-order and low byte.With the highlighted mark of italic Remember the corresponding S-GW equipment of information indicated.MME equipment parses S-GW equipment by reading the partial data.

It is that the mechanism for resolving of S-GW network element parsing is carried out using TA parameter using the prior art, but this analytical engine There is following two aspect in system:

(1) S-GW and P-GW network element can not carry out accurate match.

In the existing net equipment of each producer of 4G, S-GW equipment and P-GW equipment are generally all closed the hardware set as one and are set It is standby, it can be collectively referred to as SAEGW, in closing the hardware SAEGW set, the accurate match of S-GW and P-GW just become particularly important. If the P-GW equipment of the data feedback channel of the service selection of S-GW is to close the equipment set, data can be directly using hard The internal bus of part platform is transmitted.If the P-GW equipment of the data feedback channel of the service selection of S-GW is other hard In part equipment, then data just need to carry out transfer transmission by the router between two hardware devices.It is single in 4G network The data transmission bauds of user is all in the order of magnitude of 10M/S.So carrying out transfer using router, it is easy in core-network side Bandwidth bottleneck is caused, the service-aware speed of user is influenced.

And in existing P-GW mechanism for resolving, use the mode of access point name (APN) to be parsed, that is, The APN information that MME is reported according to user terminal, to be determined as the P-GW equipment of its service.Its data is formulated as follows: runic is high Highlights is divided into APN information, and the high bright part of italic is P-GW information.

CMNET NAPTR 20065525"S""x-3gpp-P-GW:x-s5-gtp:x-s8-gtp:x-gn"""P-GW- list-1.sy.ln.node.epc.mnc000.mcc460.3gppnetwork.org.

The TA parameter as used in the analytic technique of S-GW parsed and the analytic technique of P-GW used in APN Information is parsed, therefore, it is impossible to ensure the accurate matching of S-GW and P-GW.A large amount of S-GW equipment certainly will be will cause to carry out Business can not be accurately sent in the P-GW for closing and setting by business when transmitting, to cause due to needing in router data The bandwidth bottleneck for the core net pointed out before, the problem of influencing the business usage experience of user.

(2) it will cause the additional hand off signaling expense in TAU process using TA information parsing S-GW.

In 4G network, it is location information that TA (for main tracking area) is representative.When the location information of user changes, Namely when TA changes, the parsing of S-GW equipment is being carried out using TA, will result in the switching of S-GW equipment.

TAU process in 4G network will cause once the TA information that i.e. TA more new technological process includes: user changes The switching flow of S-GW.And in S-GW switching, the old and new's S-GW equipment needs to upload user information, user and the caching of downloading The information such as data interact, and the equipment such as MME, P-GW of other interconnections are also required to carry out the update of related data information, this The data interaction of class can occupy a large amount of network bandwidth.

It can be seen that: when the mode according to TA parameter carries out the network element parsing of S-GW, when the position of user changes, that is, When TA changes, the switching of S-GW network element will cause, cause additional hand off signaling expense in TAU process.

For above-mentioned both sides problem, there is no effective solution in the related technology.

In one embodiment of the embodiment of the present invention, described device further include:

The embodiment of the present invention is illustrated using application scenarios below:

The parsing of S-GW equipment is carried out using the mode of APN, specific implementation is as follows: the configuration data on modification DNS, When carrying out S-GW parsing, it is revised as being parsed using the mode of APN:

The parsing data configuration of S-GW is as follows:

CMNET NAPTR 20065525"S""x-3gpp-S-GW:x-s5-gtp:x-s11:x-s8-gtp:x-gn"""S- GW-pool-3.sy.ln.node.epc.mnc000.mcc460.3gppnetwork.org.

The parsing data configuration of P-GW is as follows:

Application scenarios one: the scene of S-GW is parsed using APN mode, as shown in Figure 5, comprising the following steps:

Step 501.MME equipment initiating business request initiates the analysis request that S-GW is addressed, parsing to DNS equipment first APN information is carried in request, it may be assumed that S-GW analysis request is initiated in a manner of APN.

After step 502.DNS equipment receives the analysis request that MME addresses S-GW, due to being modified in DNS equipment Configuration data are as follows: parsed when S-GW parsing using the mode of APN, therefore, APN letter is found in configuration data After breath, obtained that S-GW parsing result will be converted into the business of S-GW to S-GW parsing result according to modified configuration data Address simultaneously feeds back to MME.

Here, with above-mentioned parsing data instance, DNS equipment first searches the APN information in configuration data, when MME is initiated APN be CMNET when, dns resolution result be S-GW-pool-3.Then DNS converts service IP address for the S-GW title again Information feeds back to MME.

After step 503.MME obtains the services addresses of S-GW, data link is established with the S-GW and is linked.

Step 504.MME initiates the analysis request that P-GW is addressed to DNS equipment, carries APN information in analysis request, it may be assumed that P-GW analysis request is initiated in a manner of APN.

After step 505.DNS equipment receives the analysis request that MME addresses P-GW, due to being modified in DNS equipment Configuration data are as follows: parsed when P-GW parsing using the mode of APN, therefore, APN letter is found in configuration data After breath, obtained that P-GW parsing result will be converted into the business of P-GW to S-GW parsing result according to modified configuration data Address simultaneously feeds back to MME.

Here, with above-mentioned parsing data instance, when the APN that MME is initiated is CMNET, dns resolution result is P-GW- list-1.Then DNS converts service IP address information for the P-GW title again, feeds back to MME.

After step 506.MME obtains the services addresses of P-GW, data link is established with the P-GW and is linked.

From the process of above-mentioned Fig. 5 as can be seen that when S-GW and P-GW is parsed using APN, in DNS equipment It is able to carry out control, the S-GW services addresses returned and P-GW services addresses is made to close equipment.

In conclusion carrying out the parsing of S-GW equipment using the mode of APN, the analysis mode of S-GW and P-GW can be made to protect It holds unanimously, this ensures that the SAEGW equipment set for conjunction, and DNS can ensure to be resolved to when carrying out P-GW parsing The equipment set is closed with S-GW.If the P-GW equipment of the data feedback channel of the service selection of S-GW is to close the equipment set, data It can directly be transmitted using the internal bus of hardware platform.Bandwidth resources have been saved, while can guarantee user data Transmission rate, promote the usage experience of user.

Meanwhile S-GW equipment is parsed using the mode of APN, it can effectively avoid the change due to customer position information and make At S-GW switching.Since user is when using 4G business, the APN that user uses be always maintained at it is constant, it is all to use APN Mode parse S-GW equipment, user complete 4G network terminal attachment flow would not after determining S-GW by APN In the switching flow that S-GW occurs.It avoids S-GW switching in TAU process and causes additional hand off signaling expense, saved bandwidth Resource, promotes network utilization efficiency, and the process of application scenarios two below exactly avoids S-GW from cutting using same mechanism for resolving The process changed.

Application scenarios two: the TAU process of APN parsing S-GW is used, it can be seen that be different from Fig. 3 using existing analytical engine S-GW caused by disunity processed switches, and the S-GW equipment in Fig. 6 no longer switches, and shown in Fig. 3 two are not present in Fig. 6 A S-GW (source S-GW and target S-GW), since there is no S-GW, therefore, only one S-GW in Fig. 6.

This application scene uses the embodiment of the present invention, is parsed in the analytic technique of S-GW using APN information, and right It is also parsed using APN information in the analytic technique of P-GW, mechanism for resolving is unified, inaccurately causes so as to avoid matching The bandwidth bottleneck for stating the core net pointed out, the problem of influencing the service-aware speed of user, due also to APN information is access point letter Breath, is not the location information of user equipment, then carrying out S-GW parsing based on APN information will not be due to the change of customer position information And S-GW frequent switching is caused, the switching of S-GW is not present in the TAU process of parsing S-GW as shown in FIG. 6, and the process of Fig. 6 includes Following steps:

Step 601.UE sends TAU Request/Combined TAU Request to New MME by eNodeB and disappears Breath；

Step 602.New MME sends Context Request message to Old MME；

Step 603.Old MME returns to Context Response to New MME；

Step 604. interacts Security functions message；

Step 605.New MME sends Contest Acknowledge message to Old MME；

Step 606.New MME sends Modify Bearer Request message to S-GW；

Step 607.S-GW returns to Modify Bearer Response message to New MME；

Step 608.New MME sends Updata Location Request message to HSS；

Step 609.HSS sends Cancel Location message to Old MME；

Step 610.Old MME sends Cancel Location Acknowledge message to HSS；

Step 611.HSS returns to Updata Location Response message to New MME；

Step 612.New MME sends Location Updata Request message to MSC/VLR；

Step 613.MSC/VLR returns to Location Updata Accept message to New MME；

Step 614.New MME returns to TAU Accept message to UE；

Step 615.UE sends TAU Complete to New MME；

Step 616.New MME sends TMSI Reallocation Complete message to EIR；

Step 617.New MME sends UE Context Release Command message to eNodeB；

Step 618.eNodeB sends UE Context Release Complete message to New MME.

It is had the beneficial effect that using what the embodiment of the present invention reached

Using the embodiment of the present invention, compensates in existing procedure and carry out S-GW equipment using LTE customer position information TA Selection and parse existing two problems:

1) for the problem of S-GW and P-GW equipment in the prior art can not carry out accurate match, since P-GW is used APN is parsed, if S-GW is parsed using TA, not can guarantee the accurate match of S-GW and P-GW equipment, will certainly It causes a large amount of S-GW equipment that can not accurately be sent to business in carry out business transmission in the P-GW for closing and setting, causes core The bandwidth bottleneck of net.

And the embodiment of the present invention is used, the mode of APN has been used to carry out the selection and parsing of S-GW equipment, can make S- The analysis mode of GW and P-GW is consistent, this ensures that the SAEGW equipment set for conjunction, and DNS can ensure carrying out When P-GW is parsed, is resolved to and close the equipment set with S-GW.If the P-GW equipment of the data feedback channel of the service selection of S-GW It is to close the equipment set, data can be transmitted directly using the internal bus of hardware platform.Bandwidth resources have been saved, It can guarantee the transmission rate of user data simultaneously, promote user's perception.

That is, obtaining including P-GW/S-GW all using parsing using APN information for P-GW and S-GW Parsing result not will cause the bandwidth bottleneck of core net so as to reach accurate matched purpose.

2) lead to the switching problem of S-GW network element for parsing in the prior art using the network element that the mode of TA carries out S-GW For, when the position of user changes, that is, TA changes, it will cause the switching of S-GW network element, in TAU process Cause additional hand off signaling expense.

And the embodiment of the present invention is used, S-GW equipment is parsed using the mode of APN, can effectively be avoided due to user location The change of information and caused by S-GW switch.Since user is when using 4G business, the APN that user uses be always maintained at it is constant , all modes using APN parse S-GW equipment, in the terminal attachment flow that user completes 4G network, determine S- by APN It, would not be in the switching flow that S-GW occurs after GW.Avoiding S-GW switching in TAU process causes additional hand off signaling to open Pin has saved bandwidth resources, promotes network utilization efficiency.

That is, being not in cutting for S-GW for P-GW and S-GW all using being parsed using APN information It changes, to not will cause additional hand off signaling expense in TAU process.
