Fig. 1 is a load creating method embodiment flow chart of the present invention, and as shown in Figure 1, this method comprises:
Step 100, reception Indication message comprise gateway device information in the described Indication message;
When the gateway device that S-GW and Mobility Management Entity are selected is created carrying, adopt corresponding with it interface to communicate according to the selected gateway device type of Mobility Management Entity.Mobility Management Entity is after having determined gateway device, to send gateway device information to gateway, described gateway device information is the relevant information of selected gateway device, the form of expression of this information can be an indication gateway device type, for example " GGSN mode " still is " P-GW mode ", general packet radio service tunnel agreement (the GPRS Tunneling Protocol that perhaps indicates gateway device to adopt; Hereinafter to be referred as the GTP agreement) type, for example GTPv0, GTPv1 or GTPv2, perhaps service quality is (hereinafter to be referred as QoS) type, for example " GPRS QoS mode " or " EPS QoS mode ".Described gateway device information is the reference information that the S-GW selection is got in touch with what style interface and gateway device.
Step 101, determine the type of the gateway device corresponding and the selection interface corresponding with described gateway device with described gateway device information;
S-GW receives that the relevant information of gateway device type judges the type of identification gateway device later on, and then selects appropriate interface to communicate by letter with gateway device, sends corresponding message and arrives gateway device.S-GW disposes two complete equipment interfaces, be respectively S5/S8 interface and Gn/Gp interface, wherein the Gn/Gp interface be for the existing gateway device GPRS of compatibility (be called for short: GPRS) gateway support node (hereinafter to be referred as: GGSN), the S5/S8 interface is to be used for carrying out using when mutual with P-GW.The difference of S5/S8 interface and Gn/Gp interface is, the type of message on the distinct interface, cell and GTP version, QoS type are all different.
S-GW then uses the Gn/Gp interface to send the load creating solicited message and create carrying to GGSN if judge that gateway device is GGSN; If judge that gateway device is P-GW, then use the S5/S8 interface to send default bearer request to create information and establishment carrying.The criterion of judging is: when the relevant information of gateway device type was directly indicated the gateway device type, S-GW directly judged and gets final product; If what the relevant information of gateway device type was carried is GTP version information or QoS model information, GTP release type and QoS type according to gateway device type and its employing has relation one to one so, and employed GTP release type of different gateway devices type or carrying QoS type also are different.After selecting gateway device, GTP version and QoS type that gateway device adopted are also just decided.Concrete, GGSN uses " GTPv0 " or " GTPv1 " and " GPRS QoS Mode ", and P-GW uses " GTPv2 " and " EPS QoS Mode ".That is to say that the different GTP versions or the QoS model that use by gateway device also can identify and they corresponding different gateway devices types, thereby S-GW can judge.When not carrying gateway device information in the Indication message, the S-GW acquiescence is used the S5/S8 interface communication.
Step 102, utilize described interface and described gateway device to create carrying.
Described Mobility Management Entity also will be kept at this indication information in user's the context when S-GW sends indication information.S-GW determines to use the appropriate interface type to communicate by letter with described gateway device after receiving indication information.Here it should be noted that in real network is disposed P-GW may be by the GGSN upgrading, thus P-GW and GGSN can be physically unify, independent entity in logic, this embodiment is described from logic function.
Gateway receives before the described Indication message, Mobility Management Entity will be according to the ability information of user terminal and/or the CAMEL-Subscription-Information of described user terminal, perhaps according to the release type or the device class of Mobility Management Entity, determine selected gateway device, and generate the Indication message that comprises gateway device information.Described Mobility Management Entity comprises SGSN or MME, user terminal is (hereinafter to be referred as: ability information UE) the following several method of can having originated, a kind of is the ability information that carries user terminal at UE when request (" Attach Request ") or position updating request (Routing Area Update request " RAURequest " or tracing section updating request " TAU Request ") are adhered in the Mobility Management Entity transmission, or sends activation packet data protocol (Packet Data Protocol at UE; Hereinafter to be referred as: PDP) context request or send public data network (hereinafter to be referred as: PDN) during connection request, according to the ability information of the user terminal of preserving in the existing user's context, the ability information of terminal comprises terminal and whether is supported in Long Term Evolution (Long Term Evolution; Hereinafter to be referred as: the LTE) ability of network insertion.The subscription data information of user terminal is to adhere in the process of request in this terminal, and Mobility Management Entity is after HSS sends position updating request, and HSS inserts to Mobility Management Entity that the subscription data of user terminal obtains.
Fig. 2 is UE attachment flow signaling process figure among the load creating method embodiment of the present invention, as shown in Figure 2, comprising:
Step 1a, UE send Attach Request message to Mobility Management Entity; Mobility Management Entity is SGSN or MME;
The custom IC that step 2a, Mobility Management Entity obtain UE (is called for short: IMSI) information, and it is carried out authentication;
Step 3a, Mobility Management Entity send position updating request to HSS, the registration Mobility Management Entity;
Step 4a, HSS insert subscription data to Mobility Management Entity;
Step 5a, Mobility Management Entity send default bearer request to create message to S-GW, carry the relevant information of selected gateway device type in described default bearer request to create message;
Step 6a, S-GW adopt the S5/S8 interface type and send according to the indication information decision of Mobility Management Entity and create the default bearer request message to P-GW;
Step 7a, S-GW adopt the Gn/Gp interface type and send according to the indication information decision of Mobility Management Entity and create bearing request message to GGSN.
Step 6a and step 7a are two kinds of possible processing modes in the above-mentioned flow process, in the application of reality process selecting step 6a and step 7a the two one of carry out.
More than initiate to adhere to the flow process of request for UE, send activation PDP Context request message or PDN connection request message if step 1a is UE to Mobility Management Entity, then this flow process directly forwards step 5a to.The request message that send to activate PDP Context as UE may be to activate default bearer to SGSN, or activation new business; When UE sends the PDN connection request to MME, then be the default bearer that activates a PDN network.
Introduce Mobility Management Entity in conjunction with above-mentioned flow process and indicate S-GW to select the method for which kind of interface for use, specifically can have following several according to the ability information and the subscription data of user terminal:
Wherein a kind of is in the process that user terminal adheres to, when Mobility Management Entity sends location update request message to HSS, indication HSS inserts required subscription data, HHS increases a signatory person of field indication as indicated and inserts Limit Type in subscription data, user contracting data on the HSS has the cell of an ARD to characterize user's access restriction, increases an option-LTE access and is used for representing whether the user supports to insert the LTE network.When not allowing LTE to insert, mobile management network element MME can refuse UE adhering at the LTE network.
Mobility Management Entity sends location update request message to HSS in step 3a, in this message, carry parameter, for example the parameter type information (DataType) of required subscription data or the ability information of terminal are indicated its desired parameter type that obtains, and specifically are divided into three kinds of situations:
(1) if UE inserts from the GERAN/UTRAN wireless access system, and the ability of user terminal indication UE can not support the LTE connecting system and not support packet-based core networks evolution EPC network characteristic that then SGSN can only wish to obtain the GPRS parameter to the HSS indication in the step 3a of flow process.SGSN receives that HSS inserts after the GPRS subscription data, for UE selects GGSN;
(2) if UE inserts from the E-UTRAN wireless access system, and the ability of user terminal indication UE can not support the GERAN/UTRAN connecting system, and then MME can be in the step 3a of flow process only wishes to obtain grouping system evolution (hereinafter to be referred as EPS) subscription data to the HSS indication.MME receives that HSS inserts after the EPS subscription data, for UE selects P-GW;
(3) if ability of user terminal indication UE can support GERAN/UTRAN and LTE to insert, then no matter UE from which connecting system inserts, and mobile management network element all wishes to obtain simultaneously GPRS subscription data and EPS subscription data to the HSS indication in the step 3a of flow process.Allow LTE to insert according to inserting Limit Type if insert restriction this moment, presses the mobile management network element request so, and mobile management network element receives that HSS inserts GPRS subscription data and EPS subscription data, for UE selects P-GW; Do not allow LTE to insert if insert restriction, HSS may only insert the GPRS subscription data so, and mobile management network element SGSN is that UE selects GGSN.In addition, HSS can think that also the rank of mobile management network element requirement is higher this moment, still inserts GPRS subscription data and EPS subscription data, and mobile management network element is that UE selects P-GW so.
It is that Mobility Management Entity selects gateway device to select according to subscription data that Mobility Management Entity is selected the another kind of method of gateway device.The insertion strategy that is specially subscription data is by HSS or HLR self decision, if mobile management network element is received the subscription data of GPRS, then mobile management network element is selected GGSN; If receive the subscription data of EPS, then select P-GW.
It is that Mobility Management Entity is selected gateway device according to ability of user terminal that Mobility Management Entity is selected the another kind of method of gateway device.Be specially if UE inserts from the GERAN/UTRAN wireless access system, SGSN will select suitable gateway device according to the terminal capability of UE, if showing, the terminal capability of UE support LTE to insert or support packet-based core networks evolution EPC network characteristic, SGSN is that UE selects P-GW so, relevant if desired adaptively finished by SGSN itself or S-GW.If do not support the LTE access or do not support that packet-based core networks evolution EPC network characteristic SGSN is that UE selects GGSN.If UE inserts from the E-UTRAN wireless access system, then MME is that UE selects P-GW.
It is to select according to the release type of mobile management network element that Mobility Management Entity is selected the another kind of method of gateway device, is specially if Mobility Management Entity self is the Rel-8-Mobility Management Entity, and then Mobility Management Entity is that UE selects P-GW; If Mobility Management Entity self is before early version, i.e. the Mobility Management Entity of the version before the Rel-8 version, then Mobility Management Entity is that UE selects GGSN.
It is to select according to the device class of mobile management network element that Mobility Management Entity is selected the another kind of method of gateway device, is specially if the device class of Mobility Management Entity is MME.Then select P-GW for UE; If the device class of Mobility Management Entity is SGSN, then select GGSN for UE.
Wherein, gateway device type and address are used APN to resolve by mobile management network element and are obtained, and are GGSN independently entirely if analysis result shows optional gateway device, and mobile management network element can only be selected GGSN this moment so.Since after equipment be GGSN mostly and the equipment of P-GW unification, both obtained P-GW, so, can use above method selection gateway device if analysis result shows to be P-GW entirely or independently GGSN and P-GW are arranged from the GGSN upgrading.Selecting gateway device in the present embodiment is to carry out at the logic function of different gateway devices.
After Mobility Management Entity chooses gateway device,, then to generate the indication information that comprises the GGSN relevant information if that selection is GGSN; If that select is P-GW, then to generate the indication information that comprises the P-GW relevant information.Mobility Management Entity also will be kept at this indication information in the context of user terminal simultaneously, so that use in the follow-up flow process.
Among the load creating method embodiment of the present invention, S-GW can be according to the indication information that comprises gateway device information of Mobility Management Entity transmission, thereby the type of judging selected gateway device is selected corresponding interface and selected gateway device to get in touch and is created carrying, solved the problem that S-GW selects interface suitable and gateway device to get in touch, and error rate is lower, can't cause professional time delay.
