In practical application, final jump of the base station as mobile network appliance can be by customer service via local broadband It will be in data local routing to Internet.Base station is as local unloading point, it is therefore desirable to which base station can distinguish the use of required LBO Family.And at the beginning of LTE network designs, in order to enhance the safety of network, the NAS message transmitted between UE and MME is typically to add Close, eNodeB can not know the information of user.Therefore, user cannot be distinguished when receiving and dispatching the business datum of user in eNodeB, Cannot LBO processing selectively be carried out to certain customers.And in order to solve this technical problem, need enterprise, garden or In mansion, distinguishes different users and choose whether to carry out local unloading to the data of the user, i.e., for belonging to enterprises User just do local unloading, and for the user of enterprise external (such as accessing the guest of the enterprise, client) without doing local Unloading.The present invention is to be proposed based on the above scene, can refer to the record of following examples in detail.
Fig. 1 is the flow chart of the data message processing method embodiment one of the present invention.As shown in Figure 1, the number of the present embodiment According to message processing method, following steps are can specifically include：
100, the data message of UE is connect；
Specifically, the data message of the UE of the present embodiment can be the uplink data messages of uplink sent by UE, also may be used Think the downlink data message of downlink sent to UE.
101, according to the IP address and default evolution radio access bearer (Evolved Radio Access for presetting UE Bearer；E-RAB the tactful relationship of local unloading between mark), judges whether the data message of UE needs to carry out local unload Load processing；When data message needs to carry out local unloading processing, step 102 is executed；Otherwise, data are conventionally handled Message；
That is, the corresponding UE of IP address included in the local tactful relationship of unloading can do this unloading processing, In this way, the processing of LBO can be carried out according to UE.
102, local unloading processing is carried out to data message.
The executive agent of the data message processing method of the present embodiment is base station.In the present embodiment, carry out at local unloading The data message of reason is the data message of the UE corresponding to the user of local enterprise or garden.Such as specifically, in enterprise In the network built with operators in co-operation, i.e., enterprise's offer base station site assistance operator builds base station and is covered with enhancing wireless signal Lid.Data message processing method through this embodiment can carry out unloading processing to the data message of enterprise customer, so as to To strive for more preferential rate to enterprise staff；For operator, enterprise is that operator solves the problems, such as the siting of station While, develop client for operator, i.e. enterprise customer walks out garden and can be accessed by the macro base station of operator, Er Qieyou It is locally unloaded in business data message flow, a large amount of core net dilatation expense is saved for operator.
Therefore, the data message processing method of the present embodiment, by receiving data message；According to the IP address of default UE The tactful relationship of local unloading between the mark of E-RAB, judges whether the data message of the UE needs to carry out at local unloading Reason；When data message needs to carry out local unloading processing, local unloading processing is carried out to data message, to realize base station pair The data message of reception is analyzed, to need the data message that the data message such as enterprise customer of local unloading processing initiates into Row local unloading processing, so as to be saved and core net Internet resources when business tie-up networking for operator；It improves simultaneously The efficiency of transmission of data message, and save network charges for local user.
Still optionally further, on the basis of the technical solution of above-mentioned embodiment illustrated in fig. 1, wherein step 100 " receives The data message of UE " can specifically include two kinds of situations：It receives the uplink data messages of UE and receives the downlink data report of UE Text.
For example, when the data message of the UE of reception is uplink data messages, step 100 can specifically include：Receive UE Pass through corresponding first evolution radio access bearer (Evolved Radio Access Bearer；E-RAB) the upper line number sent According to message.
At this time accordingly, step 101 " is unloaded according to the local between the IP address of default UE and the mark of default E-RAB Tactful relationship, judges whether the data message of UE needs to carry out local unloading processing ", it can specifically include：Obtain the first E-RAB Mark；Then judge whether to include in the local mark for unloading the default E-RAB in tactful relationship the mark of the first E-RAB； If needing to carry out local unloading processing to uplink data messages including determining, otherwise uplink data messages need not be carried out local Unloading is handled.
At this time accordingly, step 102 " carrying out local unloading processing to data message ", can specifically include：By upper line number It is forwarded to the corresponding outlet of local unloading according to message.
For another example when the data message of reception is downlink data message, corresponding step 101 is " according to the IP of default UE The tactful relationship of local unloading between address and the mark of default E-RAB, it is local to judge whether the data message of UE needs to carry out Unloading is handled ", it can specifically include：The IP for the destination UE that downlink data message is sent is obtained from downlink data message Location；Whether include the IP address of destination UE in the IP address of default UE in inquiry local policy relationship, if including, really Determine downlink data message to need to carry out local unloading processing；It is namely inquired according to the purpose IP address of downlink data message default UE IP address and the mark of default E-RAB between the tactful relationship of local unloading, if inquiring, to downlink data report Text carries out local unloading processing；If otherwise inquiry is less than downlink data message need not carry out local unloading processing.
Furthermore it is also possible to which GPRS encapsulation, the number of non-local UE need not be carried out according to the data message for being set as local UE GPRS encapsulation is carried out according to message.It at this time can be by judging whether downlink data message is GPRS Tunnel Protocol (GPRS Tunneling Protocol；GTP) the data message encapsulated；It needs to carry out local unload to downlink data message if it is not, determining Load processing；Otherwise, if downlink data message is the data message of GTP encapsulation, downlink data message need not be carried out local Unloading is handled.
Specifically, local unloading processing is carried out to downlink data message, can specifically include：According to the IP of default UE The tactful relationship of local unloading between location and the mark of default E-RAB, obtains the mark of corresponding 2nd E-RAB in the addresses IP of UE Know；Downlink data message is finally forwarded to the corresponding 2nd E-RAB processing of mark of the 2nd E-RAB.
Still optionally further, on the basis of the technical solution of above-described embodiment, whether step 101 " judges data message Need to carry out local unloading processing " before, can also include：It establishes between the IP address and the mark of default E-RAB for presetting UE The tactful relationship of local unloading, there is such tactful relationship of local unloading, then corresponding data message needs to execute local unloads Load processing；Otherwise corresponding data message need not execute local unloading processing.
Further, " local between the IP address and the mark of default E-RAB of presetting UE is established in above-described embodiment Before the tactful relationship of unloading ", can also include：Obtain the IP address for presetting UE；With the default E-RAB obtained and default UE is established Mark.
The IP address for presetting UE is wherein obtained, can specifically include：From the NAS message transmitted between default UE and MME Obtain the IP address for presetting UE；It is preset in MME including presetting the corresponding international mobile subscriber identitys of UE (International Mobile Subscriber Identification Number；IMSI list list), name are single-row The corresponding default UE of IMSI in table are able to carry out local unloading strategy；Or it receives the carrying that local MME is sent and presets UE's The local unloading instruction information of IP address；And the IP address for presetting UE is obtained in instruction information from local unload；In local MME It is preset with the list list including presetting the corresponding IMSI of UE, the corresponding default UE of IMSI in list list are able to carry out local Unloading strategy.
For example, can specifically be implemented by the following steps：
1, enterprise customer's white list and NAS encryption policies are configured on MME, for belonging to the NAS message of enterprise user device Without encryption；
The enterprise customer's white list configured on MME includes the IMSI of the UE of multiple preset enterprise customers.NAS is encrypted Strategy be the corresponding UE of each IMSI when carrying out NAS safe handlings, determine it is not encrypted.
2, MME receives the NAS access requests of UE, determines whether to disappear to the NAS of the UE according to the NAS encryption policies configured Breath is encrypted；
Specifically, MME extracts the IMSI of enterprise UE from access request message, from the enterprise customer's white list configured The IMSI of the UE is searched, if it is found, then determination is not encrypted the NAS message of the UE；It if it is not found, can be just like Lower two kinds of modes of operation：The NAS message encryptions to the UE are determined, alternatively, the base station of notice UE access reselects MME；
3, for the not encrypted UE of NAS message, the IP address of UE is extracted in base station from the NAS message of UE, if be extracted into Work(determines that the UE is the UE of enterprise, thens follow the steps 4；If extraction failure, is based on normal process, sends traffic to fortune Seek quotient's network；
4, the IP address of UE is extracted in base station from the NAS message of UE, stores the IP address, while to the IP address pair of the UE The E-RAB answered does LBO marks, and the IP address for establishing UE and the correspondence between the ID of the E-RAB of drink, is unloaded as local Carry tactful relationship.
5, base station is based on the tactful relationship of local unloading, the uplink and downlink business datum message of the UE received is carried out local Unloading is handled.
Specifically, base station receives the data message sent by E-RAB, if including in locally unloading tactful relationship The ID of the E-RAB, then directly transmitted away, i.e. Local Breakout go out, if the E-RAB is not identified as LBO, It is then non-LBO business datums, then is sent to GTP processing modules according to normal process, processing is packaged by GTP processing modules, and It sends the GTP messages after encapsulation and gives corresponding gateway (Serving Gateway；SGW).Similarly, base station is for receiving The downlink service data of UE is inquired LBO marks by the purpose IP address of the downlink message, then is sent by corresponding E-RAB To UE.
Still optionally further, in the data processing method of above-described embodiment, local unloading strategy can also be in small base station (Smallcell) switch between.Therefore, the data processing method of the present embodiment can also include the following steps：
(1) switching request message is sent to purpose base station, the addresses IP of UE is carried in the switching request message.
The base station of the executive agent of the present embodiment can be source base station.That is, the data processing method of the present embodiment In, using the base station as source base station for technical scheme of the present invention is described.
(2) switching response message that purpose base station is sent is received；I.e. purpose base station is agreed to receive the switching that source base station is sent Request.
(3) it is established between purpose eNodeB and is used for data forwarding tunnel about the unidirectional of the UE.Due to the IP of UE Location does not change, and therefore, the data of downlink, which are given tacit consent to, is sent to source base station, for this purpose, source base station is needed this after the completion of switching A little data are forwarded to purpose base station by the tunnel that this step is established.Data forwarding tunnel can also be identified, and established herein Correspondence between the IP address of the UE and the mark of data forwarding tunnel corresponds to convenient for subsequently being obtained according to the IP address of UE Data forwarding tunnel.
Note：During walking herein, source base station and purpose base station need to delete other data forwarding tunnels of the UE.Especially Ground, if purpose base station is base station when initially networking, downlink data is naturally sent to base station when initial networking, this When this purpose base station on data forwarding tunnel also there is no need to.
(4) the original E-RAB between UE is deleted；Due to switch over, so source base station needs between source base station again Wireless parameter is configured, the E-RAB between deleting between source base station is carried；It deletes simultaneously between the UE IP and E-RAB preserved before this Correspondence.
Further, can also include the following steps：
