Detailed description of the invention

For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.

In practical application, base station is as the final jump of mobile network appliance, it is possible to by customer service via local broadband by data local routing to Internet. Base station is as local unloading point, it is therefore desirable to the user of required LBO can be distinguished in base station. And at the beginning of LTE network designs, in order to strengthen the safety of network, the NAS message of transmission usually encryption between UE and MME, eNodeB cannot know the information of user. Therefore, eNodeB is when receiving and dispatching the business datum of user, it is impossible to distinguish user, it is impossible to optionally certain customers are carried out LBO process. And in order to solve this technical problem, need in enterprise, garden or mansion, distinguish different users and choose whether that the data to this user carry out local unloading, namely the user for belonging to enterprises just does local unloading, and user's (such as accessing the guest of this enterprise, client) of enterprise external is not done to local unloading. It is proposed that namely the present invention is based on above scene, is referred to the record of below embodiment in detail.

Fig. 1 is the flow chart of the data message processing method embodiment one of the present invention. As it is shown in figure 1, the data message processing method of the present embodiment, specifically may include steps of:

100, the data message of UE is connect;

Specifically, the data message of the UE of the present embodiment can be the up uplink data messages sent by UE, it is also possible to for the descending downlink data message to UE transmission.

101, according to presetting the IP address of UE and default evolution RAB (EvolvedRadioAccessBearer; E-RAB) the local unloading strategy relation between mark, it is judged that the data message of UE processes the need of carrying out local unloading; When data message needs to carry out local unloading process, perform step 102; Otherwise, data message is conventionally processed;

It is to say, local UE corresponding to IP address included in strategy relation that unload can do this unloading process, as such, it is possible to carry out the process of LBO according to UE.

102, data message carries out local unloading to process.

The executive agent of the data message processing method of the present embodiment is base station. In the present embodiment, carry out the data message of the UE corresponding to user that data message is local enterprise or garden that local unloading processes. Such as specifically, in the network that enterprise and operators in co-operation build, namely enterprise provides base station site to assist operator to build base station to strengthen wireless signal covering. By the data message processing method of the present embodiment, it is possible to the data message of enterprise customer is carried out unloading process, such that it is able to strive for more preferential rate to enterprise staff; For operator, enterprise is while operator solves siting of station problem, client has been developed for operator, namely enterprise customer is walked out garden and can be accessed by the macro base station of operator, and owing to business data message flow this locality unloads, save substantial amounts of core net dilatation expense for operator.

Therefore, the data message processing method of the present embodiment, by receiving data message; Local unloading strategy relation between IP address and the mark of E-RAB according to default UE, it is judged that the data message of this UE processes the need of carrying out local unloading; When data message needs to carry out local unloading process, data message carries out local unloading process, it is analyzed thus realizing the base station data message to receiving, the data message that the data message such as enterprise customer needing local unloading to process is initiated carries out local unloading and processes, such that it is able to core net Internet resources when saving with business tie-up networking for operator; Improve the efficiency of transmission of data message simultaneously, and save network charges for local user.

Still optionally further, on the basis of the technical scheme of above-mentioned embodiment illustrated in fig. 1, wherein step 100 " receiving the data message of UE ", specifically can include two kinds of situations: receive the uplink data messages of UE and receive the downlink data message of UE.

Such as, when the data message of the UE received is uplink data messages, step 100 specifically may include that and receives UE by the first corresponding evolution RAB (EvolvedRadioAccessBearer; E-RAB) uplink data messages sent.

Accordingly now, step 101 " according to the local unloading strategy relation between the IP address of default UE and the mark of default E-RAB, it is judged that the data message of UE processes the need of carrying out local unloading ", specifically may include that the mark obtaining an E-RAB; Then the mark whether including an E-RAB in the mark of the default E-RAB in local unloading strategy relation is judged; If including determining that needing that uplink data messages carries out local unloading processes, and otherwise need not carry out local unloading and process uplink data messages.

Accordingly now, data message " is carried out local unloading to process " by step 102, specifically may include that and uplink data messages is forwarded to the outlet that local unloading is corresponding.

Again such as, when the data message received is downlink data message, corresponding step 101 " according to the local unloading strategy relation between the IP address of default UE and the mark of default E-RAB; judge that the data message of UE processes the need of carrying out local unloading ", specifically may include that the IP address obtaining the destination UE that downlink data message sends from downlink data message; Whether the IP address of the default UE in inquiry local policy relation includes the IP address of destination UE, if including, it is determined that downlink data message needs to carry out local unloading and processes; Local unloading strategy relation between IP address and the mark of default E-RAB of the UE namely preset according to the purpose IP address lookup of downlink data message, if inquiring, then carries out local unloading and processes downlink data message; If otherwise inquiry less than, then downlink data message is made without local unloading and processes.

Furthermore it is also possible to be made without GPRS encapsulation according to the data message being set to local UE, the data message of non-local UE carries out GPRS encapsulation. Now can pass through to judge whether downlink data message is GPRS Tunnel Protocol (GPRSTunnelingProtocol; GTP) data message encapsulated; If it is not, determine that needing that downlink data message carries out local unloading processes; Otherwise, if the data message that downlink data message is GTP encapsulation, then downlink data message need not be carried out local unloading and process.

Specifically, downlink data message is carried out local unloading and processes, specifically may include that according to the local unloading strategy relation preset between IP address and the mark of default E-RAB of UE, obtain the mark of the 2nd E-RAB corresponding to the IP address of UE; Finally downlink data message is forwarded to the 2nd E-RAB process that the mark of the 2nd E-RAB is corresponding.

Still optionally further, on the basis of the technical scheme of above-described embodiment, before step 101 " judges that data message processes the need of carrying out local unloading ", can also include: the local unloading strategy relation setting up between IP address and the mark of default E-RAB presetting UE, have such local unloading strategy relation, then corresponding data message needs to perform local unloading and processes; Otherwise corresponding data message need not perform local unloading and process.

Further, before " the setting up the local unloading strategy relation between IP address and the mark of default E-RAB presetting UE " in above-described embodiment, it is also possible to including: obtain the IP address presetting UE; Mark with the default E-RAB obtained with default UE foundation.

Wherein obtain the IP address presetting UE, specifically may include that and the NAS message of transmission obtains the IP address presetting UE between default UE and MME; MME is preset with and includes presetting international mobile subscriber identity (InternationalMobileSubscriberIdentificationNumber corresponding for UE; IMSI) list list, the default UE corresponding for IMSI in list list is able to carry out local unloading strategy; Or receive this locality unloading instruction information of the local MME IP address carrying default UE sent; And the IP address obtaining default UE is unloaded instruction information from this locality; Being preset with, in local MME, the list list including presetting IMSI corresponding for UE, the default UE corresponding for IMSI in list list is able to carry out local unloading strategy.

Such as, specifically can be implemented by:

1, MME upper configuration enterprise customer's white list and NAS encryption policy, the NAS message for belonging to enterprise user device is not encrypted;

Enterprise customer's white list of the upper configuration of MME includes the IMSI of the UE of multiple default enterprise customer. NAS encryption policy is that corresponding for each IMSI UE is when carrying out NAS safe handling, it is determined that not to its encryption.

2, MME receives the NAS access request of UE, determines whether the NAS message of this UE is encrypted according to the NAS encryption policy configured;

Specifically, MME extracts the IMSI of enterprise UE from access request message, searches the IMSI of this UE from the enterprise customer's white list configured, if it is found, then determine and the NAS message of this UE is not encrypted; Without finding, it is possible to there is the following two kinds mode of operation: determine that the NAS message to this UE is encrypted, or, the base station that notice UE accesses reselects MME;

3, the UE that NAS message is not encrypted, the IP address of UE is extracted in base station from the NAS message of UE, if extracting successfully, it is determined that this UE is the UE of enterprise, then perform step 4; If extracting unsuccessfully, then based on normal process, send traffic to carrier network;

4, the IP address of UE is extracted in base station from the NAS message of UE, stores this IP address, the E-RAB that the IP address of this UE is corresponding does LBO mark simultaneously, and sets up the IP address of UE and to the corresponding relation between the ID of the E-RAB of drink, as this locality unloading strategy relation.

5, base station is based on this locality unloading strategy relation, and the uplink and downlink business datum message of the UE for receiving carries out local unloading and processes.

Specifically, base station receives by the E-RAB data message sent, if including the ID of this E-RAB in this locality unloading strategy relation, then being directly transmitted away, namely LocalBreakout goes out, if this E-RAB is not designated LBO, it it is then non-LBO business datum, then deliver to GTP processing module according to normal process, GTP processing module be packaged processing, and send the GTP message after encapsulation to corresponding gateway (ServingGateway; SGW). In like manner, the downlink service data of the base station UE for receiving, identified by the purpose IP address lookup LBO of this downlink message, be sent to UE again through corresponding E-RAB.

Still optionally further, in the data processing method of above-described embodiment, local unloading strategy can also switch between little base station (Smallcell). Therefore, the data processing method of the present embodiment can also comprise the steps:

(1) send handover request message to purpose base station, this handover request message is carried the IP address of UE.

The base station of the executive agent of the present embodiment can be source base station. It is to say, in the data processing method of the present embodiment, describe technical scheme for this base station as source base station.

(2) switching response message that purpose base station sends is received; Namely purpose base station is agreed to receive the handover request that source base station sends.

(3) and set up about this UE between purpose eNodeB unidirectional for data forwarding tunnel. Owing to the IP address of UE is not changed in, therefore, descending data are sent to source base station by acquiescence, and for this, having switched rear source base station needs the tunnel by these data are set up by this step to be forwarded to purpose base station. Data forwarding tunnel can also be identified herein, and set up the corresponding relation between IP address and the mark of data forwarding tunnel of this UE, it is simple to the follow-up data forwarding tunnel corresponding according to the IP address acquisition of UE.

Note: in this step process, source base station and purpose base station need to delete other the data forwarding tunnel of this UE. Especially, if base station when purpose base station is network at first, then the base station that downlink data is naturally delivered to when networking at first, now the data forwarding tunnel on this purpose base station also avoids the need for.

(4) former E-RAB between UE is deleted; Owing to switch over, carry so source base station needs and reconfigures wireless parameter, deletion and the E-RAB between source base station between source base station; Delete the corresponding relation between UEIP and the E-RAB preserved before this simultaneously.

Further, it is also possible to comprise the steps:

(5) the new downlink data message of UE is received;

(6) from new downlink data message, obtain the IP address of UE, and obtain the data forwarding tunnel that IP address is corresponding;

(7) new downlink data message is sent by this data forwarding tunnel to purpose base station, after so just achieving the switching of little base station, the forwarding of new downlink data message.

The base station that step (1)-(7) in above-described embodiment are the executive agents for the present embodiment describes technical scheme for source base station. As purpose base station, technical scheme is described using the base station of the executive agent of the present embodiment below. The data processing method of the present embodiment can also comprise the steps:

A () receives the handover request message that source base station sends, carry the IP address of UE in this handover request message;

Base station for the purpose of the base station of the executive agent of the present embodiment.

B () sends switching response message to source base station;

The unidirectional data forwarding tunnel about UE is set up between (c) and source base station; With the step (4) in above-described embodiment realize identical, with reference to the record of the step (4) in above-described embodiment, can also not repeat them here in detail.

D carrying out interacting message between () and UE, set up new evolution RAB, as the foundation sending LBO downlink data, identify this new E-RAB is the carrying of LBO simultaneously.

E () sets up the corresponding relation between the IP address of UE and the ID of new E-RAB, and be stored in by this corresponding relation in local unloading strategy relation;

F () receives the new downlink data message that source base station is sent by data forwarding tunnel.

Further, if what receive is the IP message having done GTP encapsulation, it is determined that for not being the downlink data message of LBO, go to GTP processing module according to normal handling process, the E-RAB carrying delivering to GTP carrying after finishing GTP decapsulation corresponding processes. If the new downlink data message received is the IP message not having GTP to encapsulate, then according to the E-RAB that the purpose IP address lookup of this IP message is corresponding, if inquired, then it is assumed that be the downlink data message of UE corresponding for this IP, the E-RAB carrying going to correspondence processes; Without inquiring, then it is assumed that be invalid packet, should abandon. Wherein the downlink data message of UE is sent to UE by E-RAB.

Further, it is also possible to comprise the steps:

G () receives heart uplink data messages from new E-RAB, according to new E-RAB mark, if this E-RAB is identified as LBO, be then the data message needing to carry out LBO; Otherwise, then it is not required to carry out the data message of LBO.

H new uplink data messages, according to it is confirmed that the no result needing to carry out LBO process, new uplink data messages being processed, if needing new uplink data messages is carried out LBO process, is then forwarded to the outlet of LBO by (); If new uplink data messages need not be carried out LBO process, then go to GTP processing module according to normal handling process, finish GTP add encapsulation after be forwarded to down hop again.

The data message processing method of above-described embodiment, by adopting such scheme, the base station data message to receiving can be realized be analyzed, the data message that the data message such as enterprise customer needing local unloading to process is initiated carries out local unloading and processes, such that it is able to core net Internet resources when saving with business tie-up networking for operator; Improve the efficiency of transmission of data message simultaneously, and save network charges for local user. Further, additionally it is possible to switching this locality unloading strategy between little base station, further enhancing the motility that data message processes, enhance the efficiency that data message processes.

Fig. 2 is the signaling diagram of the data message processing method enforcement two of the present invention. In the network that the data message processing method of the present embodiment uses, the little base station Smallcell that operator affixes one's name in enterprises is eNodeB, namely enterprises user is carried out local unloading by eNodeB, and eNodeB allows also to user outside enterprise and accesses, but the user of enterprise external is not carried out local unloading. As in figure 2 it is shown, the data message processing method of the present embodiment, specifically may include steps of:

200, MME upper configuration IMSI white list is as LBO strategy, and this IMSI white list includes the IMSI of the UE of multiple default enterprise customer, and UE corresponding to each IMSI is when carrying out NAS safe handling, it is determined that not to its encryption;

The IMSI white list of the LBO strategy in the present embodiment is an IMSI list. The LBO strategy of the present embodiment is the UE of the IMSI that this LBO strategy includes when carrying out NAS and processing, and it is not encrypted; It, when carrying out NAS and processing, is encrypted by the UE of the IMSI that LBO strategy does not include.

201, UE begins to adhere to mobile network, sends AttachRequest message by eNodeB to MME, carries the IMSI of UE in this AttachRequest message;

202, MME obtains the IMSI of UE the LBO strategy according to this IMSI and configuration, it is determined that the NAS message encryption policy of this UE;

Specifically, MME inquires about, from the LBO strategy of configuration, the IMSI whether including this UE, if included, it is determined that all NAS message between this UE and MME are not encrypted; If otherwise not including, then continue according to normal process, the NAS message of this UE to be encrypted.

203, to carry out NAS message according to NAS message encryption policy by eNodeB mutual for UE and MME;

204, UE authenticates successfully at mobile network authentication, and MME sends the NAS message of AttachAccept to UE by eNodeB;

205, eNodeB obtains the IP address of UE record from unencrypted AttachAccept message;

This IP address wherein recorded, the data message for follow-up this UE corresponding for IP address carries out local unloading.

Being include in the IMSI white list that LBO strategy is corresponding for the IMSI of this UE in the present embodiment, the now corresponding NAS message between UE and MME is not encrypted.
