Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

At first in conjunction with Fig. 2, the embodiment of the invention a kind of carried out information interactive method with the node of storing user subscription data describe in position updating process.As shown in Figure 2, comprising:

Step S201: the node to storing user subscription data sends position updating request, described position updating request is carried the relevant information of the node type with mobile management function of sending described position updating request, the described relevant information of node type with mobile management function comprises the node types with mobile management function that described transmission position is upgraded at least, described node types with mobile management function can directly be indicated described node types, also can come clear and definite by the indication that request is carried out location update operations to certain node type, be to close under the situation of establishing node M ME/SGSN at described node with mobile management function for example, the information that the node type with mobile management function of the described position updating request that described position updating request is carried is relevant can be carried out the indication of location update operations to MME and SGSN simultaneously for request.

Step S202: the node that obtains described storing user subscription data is according to described user contracting data with node types transmission of mobile management function.

Described position updating request can also be carried the type of the needed user contracting data of node with mobile management function that sends described position updating request, during user contracting data that the node that obtains described storing user subscription data sends according to described node types with mobile management function, the user contracting data that the node that can obtain described storing user subscription data sends according to the type of described node types with mobile management function and needed user contracting data, in other words, the node of storing user subscription data is when sending user contracting data, except that needs are considered to have the node types of mobile management function, also need to consider to have the type of the needed user contracting data of node of mobile management function, in general, the node of storing user subscription data can send the user contracting data of the needed type of node with mobile management function.

If sending the node with mobile management function of described position updating request is MME or SGSN, and the type of needed user contracting data is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types, and then the user contracting data of Huo Deing is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types.In other words, when the node with mobile management function is MME or independently during SGSN independently, if independently MME or the independently all types of user contracting datas of SGSN requirement acquisition, then the node of storing user subscription data can send to independently MME or independently SGSN with all types of user contracting datas.If sending the node with mobile management function of described position updating request is MME, and the user contracting data that described MME obtains is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types, then, subscriber equipment provides when service for it when switching to SGSN, described MME can send to SGSN with the user contracting data of SGSN corresponding types, and need not SGSN to the user contracting data of the node request corresponding types of storing user subscription data; If sending the node with mobile management function of described position updating request is SGSN, and the user contracting data that described SGSN obtains is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types, then, subscriber equipment provides when service for it when switching to MME, described SGSN can send to MME with the user contracting data of MME corresponding types, and need not MME to the user contracting data of the node request corresponding types of storing user subscription data.

Establish node M ME/SGSN if send the node with mobile management function of described position updating request for closing, and subscriber equipment carries out the position when upgrading by an entity among MME and the SGSN, and the information that the node type with mobile management function that then described position updating request is carried is relevant represents that also the node of the described storing user subscription data of needs pays the utmost attention to the mode of carrying out location update operations.Furthermore, close and establish this type of node M ME/SGSN the multiple form of expression can be arranged, the different forms of expression can be represented different information, for example, MME/SGSN can represent that subscriber equipment carries out the position by MME and upgrades, the node of storing user subscription data is when carrying out location update operations so, should preferentially carry out the location update operations corresponding with MME, when sending user contracting data, can pay the utmost attention to the user contracting data with the MME corresponding types sent to close and establish node M ME/SGSN.Certainly, establish node M ME/SGSN and do not have special requirement if close, the node of storing user subscription data generally can be established node M ME/SGSN with together sending to close with the user contracting data of MME corresponding types with the user contracting data of SGSN corresponding types.If the information that the node type with mobile management function that described position updating request is carried is relevant is also represented the node of the described storing user subscription data of needs and is paid the utmost attention to the mode of carrying out location update operations, then carry out location update operations according to the top-priority mode of described needs, the location update operations that promptly preferentially needs top-priority node is carried out not by the location update operations of top-priority node again; If successful execution need the location update operations of top-priority nodes, successful execution is not by the location update operations of top-priority node, home position upgrades the operation response to show the location update operations of only having carried out the top-priority nodes of needs.

Establish node M ME/SGSN if send the node with mobile management function of described position updating request for closing, and the address of closing the MME that establishes among the node M ME/SGSN and SGSN is inequality, then described position updating request is also carried the address of MME and the address of SGSN, so that the address of the address of the nodes records MME of storing user subscription data and SGSN.

That close that the type of establishing node M ME/SGSN represents also that the node of the described storing user subscription data of needs pays the utmost attention to the mode correspondence of carrying out location update operations is MME if described position updating request is carried, then can use a parametric representation not by the address of top-priority SGSN in described position updating request separately; That close that the type of establishing node M ME/SGSN represents also that the node of the described storing user subscription data of needs pays the utmost attention to the mode correspondence of carrying out location update operations is SGSN if described position updating request is carried, then uses a parametric representation not by the address of top-priority MME in described position updating request separately.Need to prove, comprised a address of node in the position updating request of the prior art with mobile management function, when the node with mobile management function is to close when establishing node M ME/SGSN, can use described existing address to represent the address of an entity among the MME/SGSN, the address of another entity can be used a parametric representation separately, and the parameter of using separately also is carried in the position updating request certainly.

If have between the node of the node of mobile management function and storing user subscription data and be provided with node with protocol conversion function, then the position updating request of sending to the node of storing user subscription data arrives the node of storing user subscription data by the node with protocol conversion function, and the user contracting data of acquisition is the user contracting data that obtains by the node with protocol conversion function.For example, may be provided with IWF (IWF between MME/SGSN and the HSS/HLR, InterworkingFunction), the S6a/S6d interface that is based on Diameter that adopts between MME/SGSN and the IWF, the Gr/Gr+ interface that is based on MAP that adopts between HSS/HLR and the IWF, IWF mainly finishes the function of protocol conversion.When MME/SGSN when HSS/HLR sends position updating request, MME/SGSN can send position updating request based on Diameter to IWF, IWF sends position updating request based on MAP to HSS/HLR again; When HSS/HLR when MME/SGSN sends the position and upgrades response, HSS/HLR can send based on the position of MAP to IWF and upgrade response, IWF sends based on the position of Diameter to MME/SGSN and upgrades response.

Need to prove that the executive agent of above-mentioned steps S201 and S202 can be the node with mobile management function, for example MME, SGSN or close and establish node M ME/SGSN, the node of storing user subscription data can be HSS or HLR.In addition, the node of storing user subscription data can be carried on the node of storing user subscription data in the position renewal response that the node with mobile management function sends to the user contracting data that the node with mobile management function sends.

Corresponding to method shown in Figure 2, the embodiment of the invention provides a kind of node with mobile management function.As shown in Figure 3, this node with mobile management function comprises: position updating request transmitting element 301, be used for sending position updating request to the node of storing user subscription data, described position updating request is carried described node type relevant information with mobile management function, and the described relevant information of node type with mobile management function comprises the described node types with mobile management function that sends the position renewal at least; User contracting data obtains unit 302, be used for after described position updating request transmitting element 301 sends position updating request, the node that obtains described storing user subscription data is according to described user contracting data with node types transmission of mobile management function.

At the node with mobile management function shown in Figure 3 is to close under the situation of establishing node M ME/SGSN, and the information that the node type with mobile management function of sending described position updating request that the position updating request that position updating request transmitting element 301 sends is carried is relevant can be carried out the indication of location update operations to MME and SGSN simultaneously for request.The type that the position updating request that position updating request transmitting element 301 sends can also be carried the needed user contracting data of node with mobile management function shown in Figure 3, when user contracting data obtains user contracting data that node that unit 302 obtains described storing user subscription data sends according to the node types with mobile management function shown in Figure 3, can obtain the user contracting data of the node of described storing user subscription data according to the type transmission of node types with mobile management function shown in Figure 3 and needed user contracting data, in other words, the node of storing user subscription data is when sending user contracting data, except that needs are considered to have the node types of mobile management function, also need to consider to have the type of the needed user contracting data of node of mobile management function, in general, the node of storing user subscription data can send the user contracting data of the needed type of node with mobile management function.

If the node with mobile management function shown in Figure 3 is MME or SGSN, and the type of needed user contracting data is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types, and then the user contracting data of user contracting data acquisition unit 302 acquisitions is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types.In other words, when the node with mobile management function shown in Figure 3 is MME or independently during SGSN independently, if independently MME or the independently all types of user contracting datas of SGSN requirement acquisition, then the node of storing user subscription data can send to independently MME or independently SGSN with all types of user contracting datas.If the node with mobile management function shown in Figure 3 is MME, and the user contracting data that described MME obtains is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types, then, subscriber equipment provides when service for it when switching to SGSN, described MME can send to SGSN with the user contracting data of SGSN corresponding types, and need not SGSN to the user contracting data of the node request corresponding types of storing user subscription data; If the node with mobile management function shown in Figure 3 is SGSN, and the user contracting data that described SGSN obtains is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types, then, subscriber equipment carries out the position when upgrading when switching to MME, described SGSN can send to MME with the user contracting data of MME corresponding types, and need not MME to the user contracting data of the node request corresponding types of storing user subscription data.

If the node with mobile management function shown in Figure 3 is established node M ME/SGSN for closing, and subscriber equipment carries out the position when upgrading by an entity among MME and the SGSN, and then the position updating request sent of the position updating request transmitting element 301 relevant information of the node type with mobile management function of carrying represents that also the node of the described storing user subscription data of needs pays the utmost attention to the type of user contracting data of the node transmission of the mode of carrying out location update operations and the described storing user subscription data of needs.Furthermore, close and establish this type of node M ME/SGSN the multiple form of expression can be arranged, the different forms of expression can be represented different information, for example, MME/SGSN can represent that subscriber equipment carries out the position by MME and upgrades, the node of storing user subscription data is when carrying out location update operations so, should preferentially carry out the location update operations corresponding with MME, when sending user contracting data, can pay the utmost attention to the user contracting data with the MME corresponding types sent to close and establish node M ME/SGSN.Certainly, establish node M ME/SGSN and do not have special requirement if close, the node of storing user subscription data generally can be established node M ME/SGSN with together sending to close with the user contracting data of MME corresponding types with the user contracting data of SGSN corresponding types.

If the node with mobile management function shown in Figure 3 is established node M ME/SGSN for closing, and the address of closing the MME that establishes among the node M ME/SGSN and SGSN is inequality, then the position updating request sent of position updating request transmitting element 301 is also carried the address of MME and the address of SGSN, so that the address of the address of the nodes records MME of storing user subscription data and SGSN.

If that shown in Figure 3 closing establishes that the type of node M ME/SGSN represents also that the node of the described storing user subscription data of needs pays the utmost attention to the mode correspondence of carrying out location update operations is MME, then in described position updating request, can use the address of a parametric representation SGSN separately; That close that the type of establishing node M ME/SGSN represents also that the node of the described storing user subscription data of needs pays the utmost attention to the mode correspondence of carrying out location update operations is SGSN if the position updating request that position updating request transmitting element 301 sends is carried, then uses the address of a parametric representation MME in described position updating request separately.

If be provided with node between the node of node with mobile management function shown in Figure 3 and storing user subscription data with protocol conversion function, then the position updating request sent to the node of storing user subscription data of position updating request transmitting element 301 arrives the node of storing user subscription data by the node with protocol conversion function, and it is the user contracting data that obtains by the node with protocol conversion function that user contracting data obtains the user contracting data that unit 302 obtains.

Need to prove that the node with mobile management function shown in Figure 3 can MME, SGSN or closed and establish node M ME/SGSN, the node of storing user subscription data can be HSS or HLR.In addition, the user contracting data of user contracting data acquisition unit 302 acquisitions can be carried on the node of storing user subscription data in the position renewal response that the node with mobile management function shown in Figure 3 sends.

The embodiment of the invention also provides a kind of and carry out information interactive method with the node with mobile management function in position updating process.As shown in Figure 4, comprising:

Step S401: obtain to have the position updating request that the node of mobile management function sends, described position updating request is carried the described relevant information of node type with mobile management function, and the described relevant information of node type with mobile management function comprises described node types with mobile management function at least.

Step S402: send user contracting data to described node with mobile management function according to described node types with mobile management function.

Described position updating request can also be carried described type with needed user contracting data of node of mobile management function.If described position updating request is also carried described type with needed user contracting data of node of mobile management function, then according to described node types with mobile management function when described node with mobile management function sends user contracting data, have the node types of mobile management function and the type of needed user contracting data sends user contracting data to described node with mobile management function according to described.In other words, when sending user contracting data, except that needs are considered to have the node types of mobile management function, also need to consider to have the type of the needed user contracting data of node of mobile management function, in general, the user contracting data that sends to described node with mobile management function all is the user contracting data with needed type of node of mobile management function.

If described node with mobile management function is MME or SGSN, and the type of needed user contracting data is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types, and then the user contracting data that sends to described node with mobile management function is the user contracting data of MME corresponding types and the user contracting data of SGSN corresponding types; If sending the node with mobile management function of described position updating request is MME, then, subscriber equipment provides when service for it when switching to SGSN, and described MME sends to SGSN with the user contracting data of SGSN corresponding types; If sending the node with mobile management function of described position updating request is SGSN, then, subscriber equipment provides when service for it when switching to MME, and described SGSN sends to MME with the user contracting data of MME corresponding types.

If the information that the node type with mobile management function that described position updating request is carried is relevant is also represented to pay the utmost attention to the mode of carrying out location update operations, then when carrying out location update operations, carry out location update operations according to the top-priority mode of described needs.If the information that the node type with mobile management function that described position updating request is carried is relevant is also represented the type of the top-priority user contracting data of needs, then when sending user contracting data, according to the type transmission user contracting data of the top-priority user contracting data of described needs.Furthermore, if have the node of mobile management function is to close to establish node M ME/SGSN, then close and establish this type of node M ME/SGSN the multiple form of expression can be arranged, the different forms of expression can be represented different information, for example, MME/SGSN can represent that subscriber equipment carries out the position by MME and upgrades, so when carrying out location update operations, should preferentially carry out the location update operations corresponding with MME, when sending user contracting data, can pay the utmost attention to the user contracting data with the MME corresponding types sent to close and establish node M ME/SGSN.Certainly, establish node M ME/SGSN and do not have special requirement, so generally can establish node M ME/SGSN together sending to close with the user contracting data of MME corresponding types with the user contracting data of SGSN corresponding types if close.

Establish node M ME/SGSN, close the inequality and described position updating request in the address of the MME that establishes among the node M ME/SGSN and SGSN and also carry the address of MME and the address of SGSN if send the node with mobile management function of described position updating request and be to close, then the node of storing user subscription data also will write down the address of MME and the address of SGSN after the position updating request that the node that obtains to have the mobile management function sends.

To close what establish that the relevant information representation of the node type with mobile management function that node M ME/SGSN and described position updating request carry need pay the utmost attention to the mode correspondence of carrying out location update operations be MME if send the node with mobile management function of described position updating request and be, then uses the address of a parametric representation SGSN in described position updating request separately; If that the information representation that the node type with mobile management function that described position updating request is carried is relevant need be paid the utmost attention to the mode correspondence of carrying out location update operations is SGSN, then in described position updating request, use the address of a parametric representation MME separately.

The 8th embodiment

HSS receives location update message, carries the type information and the node type relevant information of requesting users subscription data in the message.The node types relevant information and/or the requesting users subscription data type (optional) of the request that the HSS storage receives.When user contracting data took place to upgrade, HSS sent the user data update request message according to the node types relevant information and/or the requesting users subscription data type decided of storage to described node.Being designated as MME with the single node type information below is that example describes.

What single MME carried its request by the S6a interface in position updating request is that the information of EPS subscription data and the relevant information (clear and definite node type MME, or single node information+S6a interface indication information) of its node type of indication are given HSS.HSS stores the subscription data type information (optional storage) of this node types relevant information (can be the node type relevant information in the updating message of direct memory location, also can be the clear and definite node type MME that storage is derived from the node type relevant information) and/or this MME request.When the 2G/3G of follow-up respective user subscription data changes, HSS judges that this node types relevant information of storage is that the single MME node or the subscription data type of this MME request are the EPS subscription data, and HSS will not send corresponding user data update request message to this node.When the subscription data that only is applicable to SGSN of follow-up respective user changed, HSS judged that this node types relevant information of storage is single MME node, and HSS will not send corresponding user data update request message to this node.Have only when EPS subscription data or the subscription data that is applicable to MME change, HSS just sends the user data update request message to MME.

Idiographic flow as shown in figure 16.

Step S1601: single MME node sends location update request message to HSS.

Wherein, the type information that position updating request is carried the requesting users subscription data is the EPS subscription data, and reaching the node type relevant information is MME, or single node information+S6a interface indication information;

Illustrate: wherein the type information of requesting users subscription data can be indicated by the indication information of clear and definite request EPS subscription data for the EPS subscription data; Also can release by the information that does not comprise clear and definite indication request GPRS or 2G/3G subscription data in the location update request message, just asking the EPS subscription data is acquiescence or implicit.

Illustrate: the S6a interface is HSS and MME definition, S6a interface indication explanation request message is necessarily from MME or close the MME that establishes node M ME/SGSN, single node information has further been got rid of the situation of establishing node of closing, and both are single MME nodes in conjunction with clear and definite requesting node;

Step S1602:HSS carries out corresponding location update operations inspection and processing, and home position upgrades response message to requesting node;

This node type relevant information of receiving among the step S1603:HSS storing step S1601 is stored the type information of this node requesting users subscription data alternatively;

Step S1604: when user's 2G/3G subscription data upgrades (comprising increase, deletion or modification), HSS judges that the node type relevant information of storage is designated as single node MME, or the requesting users subscription data type of storage is the EPS subscription data, HSS does not trigger the user data update process, does not just send the user data update request message;

Step S1605: when user's the subscription data that only is applicable to SGSN upgraded (comprising increase, deletion or modification), HSS judged that the node type relevant information of storage is designated as single node MME, and HSS does not trigger the user data update process;

Step S1606: when user's EPS subscription data upgraded (comprising increase, deletion or modification), HSS triggered the user data update process;

User EPS subscription data after step S1607:HSS will upgrade is carried in the user data update request message and is handed down to MME.

Be meant that this user EPS part subscription data is deleted if the user EPS subscription data described in the step S1605 takes place to upgrade, then HSS carries transmission the user data update request message of corresponding subscription data deletion indication;
