Particularly, pdp context activation comprises:
Step 101, MS sends to SGSN and activates request Activate PDP Context Request, and carries quality of service request (QoS Requested) information in this request, and wireless side is carried out the RAB assignment process.
In this step, also comprise NSAPI, TI, PDP Type, PDP Address, information such as Access Point Name, QoS Requested among the Activate PDP Context Request.
Step 102, the validity of SGSN checking Activate PDP Context Request, and, initiate the Qos negotiations process to wireless side according to the QoS Requested information that activates in the request, consults successfully the back and initiate the PDP activation to GGSN and ask (Create PDP Context Request).
In this step, SGSN is specifically by using PDP Type (optional), PDP Address (optional), Access Point Name (optional) and PDP Context subscription data to verify the validity of request.
Step 103, GGSN initiates the request of chargeing to WAP gateway and begins message (Account-RequestStart), and carries the successful Qos information of consulting.
In this step, also comprise information such as subscriber phone number, terminal IP, charging ID, Qos in the request beginning message of chargeing.
Step 104, GGSN sends to SGSN and activates response message (Create PDP ContextResponse).
Step 105, WAP gateway is responded the beginning response message (Accounting-Response Start) of chargeing to GGSN.
Step 106, after SGSN receives the CREATE PDP Context RESPONSE (NSAPI, PDP ADDR, GGSN ADDR, TEID, QoS) of GGSN, pdp address, the successful information such as QoS of negotiation are sent to MS by Activate PDP Context Accept.
So far, PDP activation completes successfully, and the user reaches the standard grade successfully, can carry out service access to SP by WAP gateway, and concrete service access process comprises:
Step 107, the user initiates service request (User Request) to gateway.
Step 108, WAP gateway are resolved user's request, conduct interviews according to dependency rule and control and the forward pass information Control, and please user's request be forwarded to SP.
At present in WAP gateway, though the charging that receives in step 103 begins to comprise in the request message QoS information that consults, but WAP gateway inside does not process at QoS information, but being inserted the user, all are considered as the identical grade of service, it is transmitted user's request according to first-come-first-served policy, and in the user's request that is transmitted to SP, do not comprise QoS information.
Step 109, SP receives user's request that WAP gateway is transmitted, and response contents is returned to WAP gateway.
As previously mentioned, WAP gateway all is equal access to all users in the step 108, according to the strategy of serving earlier first, user's request is transmitted to SP.SP also asks to adopt first the strategy of service earlier to all users that receive, and for all users provide identical response contents, as information on services, content of pages and charging policy etc.
Step 110, WAP gateway receives the response contents that SP returns, and carries out suitable processing (as character set conversion, content compression etc.), and response contents is transmitted to terminal.
Step 111, the terminal parses content of pages also shows.
User's repeating step 107-111 process is initiated repeatedly service request.
The user who carries out is undertaken in the process of SP service access by WAP gateway in the manner described above, all users of WAP gateway equal access, regard as access user's service priority identical, transmit user's request coequally,, do not provide the different grades of service to different user at user's demand; SP for all users provide identical service, also can't provide differentiated service according to user characteristics after receiving user's request of WAP gateway equality forwarding.

In fact, in groups of users information and user profile, can further include QoS information, thereby make WAP gateway can preserve the QoS information of user and groups of users, and further according to user's QoS information, the priority of segmentation service, and provide service for the user according to this service priority.
In addition, can divide according to different standards when the user is divided into different groups of users, two kinds of dividing mode are provided below, a kind of is to divide according to the operator under the user, and a kind of is signatory QoS grade classification according to the user.Embodiment below by the embodiment of the invention under two kinds of dividing mode of specific embodiment explanation.
Embodiment one:
In the present embodiment, the user is divided into different groups of users according to the operator under the user.And, in user profile and groups of users information, including relevant QoS information, WAP gateway can initiatively be initiated QoS and be consulted, and holds consultation with regard to the QoS grade of MS with MS and wireless side, and preserve result after each the negotiation in user profile.
Fig. 4 is for realizing WAP user is provided the method particular flow sheet of differentiated service among the embodiment one.As shown in Figure 4, this method comprises:
Step 401 is divided into different groups of users according to the operator under the user with the user.
Operator in this step can be actual operator, also can be virtual operator.When the user registers, can select to be registered in the different operator or virtual operator, thereby can realize that the user is carried out group according to operator to be divided.
User profile and groups of users information are obtained and preserved to step 402, WAP gateway.
In this step, WAP gateway can obtain group information under user profile and the user by maintenance terminal, perhaps also can be when the user reaches the standard grade, send user profile and groups of users information by GGSN to WAP gateway, perhaps also can set up interface for third party software and the WAP gateway of preserving user profile and groups of users information, WAP gateway obtains user profile and groups of users information by described interface.
When WAP gateway receives user profile and groups of users information by GGSN, can begin message by the charging request of expansion and carry user profile and groups of users information, thereby make WAP gateway when the user reaches the standard grade, receive corresponding information.
In the present embodiment, the user profile that WAP gateway obtains can comprise user ID, and the group identification of this user place group corresponding with this user ID and this user's signatory QoS information.Wherein, user's signatory QoS information comprises the last successful QoS grade and the QoS negotiation result for the last time of consulting of this user and network, i.e. the QoS grade of Xie Shanging and whether consult successful state information.Here, to consult be that the QoS that carries out with MS and wireless side that aforesaid WAP gateway is initiatively initiated consults to the QoS of described user and network.Perhaps, user profile can further include the information such as date of last negotiation.WAP gateway can utilize form to preserve user profile, and for example table 1 is certain user's user profile signal.

Table 2
Through after the above-mentioned steps, in WAP gateway, preserved user profile and groups of users information, and in this user profile and groups of users information, comprised qos-related information.Next, when the user carried out the WAP Operational Visit, gateway can be initiated QoS according to the qos-related information that comprises in user profile and the groups of users information and be consulted.For example, can carry out according to following steps:
Step 403, in the last line process of user, the charging request that WAP gateway receives the GGSN transmission begins message, and extracts user ID and the QoS information that comprises in this message.
As previously mentioned, in the line process on the user (promptly activating the PDP process), GGSN can begin message to the WAP gateway transmission request of chargeing, and comprises that user ID and user ask in this message and SGSN and the successful QoS information of wireless side negotiation.
Step 404, WAP gateway is according to the user ID of extracting, searching the group identification and the signatory QoS information of this user ID correspondence in user profile, is index with the group identification that finds again, searches the signatory QoS scope of this group identification correspondence in groups of users information.
In this step, WAP gateway is determined corresponding user related information according to the user ID of extracting, and what preserve in for example definite table 1 is this user profile, thereby finds group identification and signatory QoS information from this table 1.Determine the relevant information of this group then according to the group identification that finds, what preserve in for example definite table 2 is this groups of users information, thereby finds signatory QoS scope from this table 2.
Step 405, WAP gateway judges whether the signatory QoS information of QoS information of carrying and this user who finds mates from the request that GGSN receives, and judge whether the QoS information of carrying in the request meets signatory QoS scope, if two kinds of QoS information matches and meet signatory QoS scope, then execution in step 406, otherwise, execution in step 407.
In this step,, judge whether two kinds of QoS information mate according to the matching strategy that sets in advance.
Particularly, a kind of decision procedure can for: in user's signatory QoS information, comprise last negotiation result,, then judge not match if this time QoS grade of request is equal to or higher than the QoS grade of last negotiation failure.For example, the last negotiation result that writes down in user's signatory QoS information is: consulting the QoS grade is 3, and negotiation result is failure; If WAP gateway receives the QoS information of carrying in the message: the QoS grade is 3 or is higher than 3, judges that so then the QoS information of this request and the signatory QoS information of preservation do not match.
Perhaps another decision procedure can for: the negotiation of WAP gateway regulation QoS grade need be carried out step by step, can not skip a grade, if QoS grade of request this time of WAP gateway reception is higher than the last the negotiation more than the successful QoS grade one-level so, then judgement does not match.For example, it is 3 that the last time of writing down in the signatory QoS information of user is consulted successful QoS grade, if the QoS grade judges so that greater than 4 the QoS information of this request and the signatory QoS information of preservation do not match in the entrained QoS information of WAP gateway reception message.
When whether the QoS information of carrying in judgement met signatory QoS scope, if the QoS grade in the QoS information of carrying is then judged accord with Q oS scope smaller or equal to the highest signatory QoS and more than or equal to signatory minimum QoS, otherwise judgement did not meet the QoS scope.
When above-mentioned two Rule of judgment all satisfy, execution in step 406, when above-mentioned two Rule of judgment are arbitrary when not satisfying, execution in step 407.
Step 406 is utilized this user's of QoS information updating of this request signatory QoS information, and the user reaches the standard grade successfully.
In this step, the QoS information of this request is saved as new the last time consult successful QoS information.
Step 407, WAP gateway is specified a QoS grade, and initiatively initiates heavily negotiations process of QoS with this QoS grade.
In this step, when WAP gateway is specified the QoS grade, according to the signatory QoS scope in the group under the QoS information of carrying in the reception information, this user, this user the last consult successful QoS grade and for the last time negotiation result carry out.
Particularly, when needs carried out the negotiation step by step of QoS, the QoS grade of WAP gateway appointment was to exceed the QoS grade of one-level than the successful QoS grade of the last time negotiation.Further, the QoS grade of appointment is in signatory QoS scope, promptly more than or equal to the highest signatory QoS and smaller or equal to signatory minimum QoS.
WAP gateway initiate mode that QoS heavily consults can for: carry out QoS to the GGSN request and heavily consult, and carry appointment the QoS grade, consult reason and pdp address.Concrete request mode can be revised QoS request message Modift Qos Request by send one to GGSN, comprises QoS grade, negotiation reason and the pdp address of appointment in this message.Wherein, the definition of Modify Qos Request can be as shown in table 3.

Step 408 after GGSN receives the request of WAP gateway transmission, according to the QoS grade and the pdp address of the appointment of carrying in the request, is upgraded PDP Context to the SGSN request, and is carried the QoS grade and the pdp address of this appointment.
In this step, GGSN to SGSN request upgrade PDP Context mode can for: GGSN sends to SGSN and revises PDP Context request message Update PDP Context Request, and carries information such as the QoS grade of appointment and pdp address in this message.
Step 409, SGSN carries out QoS to wireless side and consults according to the definite PDP Context that will upgrade of pdp address, and the QoS of negotiation is the QoS grade of appointment, consults successfully back execution in step 410.
Step 410, SGSN revises PDP Context to the MS request, and carries the QoS grade of pdp address and appointment, and whether inquiry MS accepts the QoS grade is revised as the QoS grade of appointment.
In this step, the mode that SGSN revises PDP Context to the MS request is: SGSN sends to MS and revises PDP Context request message Modify PDP Context Request, and carries the QoS grade of pdp address and appointment in this message.
Step 411, MS judges whether to accept the QoS grade of appointment, if accept, then execution in step 412, otherwise execution in step 415.
Step 412, MS returns to SGSN and consults successful information, and wireless side is carried out RAB assignment again.
In this step, MS to SGSN return consult successful information mode can for: MS sends PDP context modification to SGSN and accepts message Modify PDP Context Accept.
Step 413, SGSN will consult successful information and send to GGSN.
In this step, SGSN will consult the mode that successful information sends to GGSN can upgrade PDP Context response message Update PDP Context Response for: SGSN sends to GGSN, and carries and consult successful QoS grade.
Step 414, GGSN will consult successful information and send to WAP gateway, and carry the QoS information of successfully consulting, WAP gateway update user information.
In this step, GGSN will consult the mode that successful information sends to WAP gateway can revise QoS response message Modify Qos Response for: GGSN returns to WAP gateway, and carries the success or not sign.Wherein, the definition of Modify Qos Response can be as shown in table 4.

Table 4
WAP gateway receives the negotiation successful information that GGSN sends, the user's that the QoS information updating self of the successful negotiation that utilization is carried is preserved signatory QoS information, and the user reaches the standard grade successfully.Since then, WAP gateway is consulted successful QoS grade according to the last time in the signatory QoS information of this user, for the user provides the access service of different priorities and bandwidth service etc., for example, when the WAP gateway load is heavier, is preferably the last successful higher user of QoS grade of negotiation access service is provided; Perhaps, distribute higher bandwidth resources etc. for the higher user of QoS grade.
Step 415, terminal is initiated the PDP deactivation process, sends deexcitation PDP Context request message Deactivate PDP Context Request to SGSN.
Step 416, SGSN receives MS deexcitation request, sends deletion PDP Context response message Delete PDP Context Response to GGSN.
Step 417, GGSN sends to WAP gateway and revises QoS response message Modify QosResponse, and carrying failure cause (as: Qos is rejected), state flag bit Status for failing, WAP gateway upgrades user's signatory QoS information according to the Modify Qos Response that receives; Send deletion PDP Context response message Delete PDP Context Response to SGSN simultaneously.
In this step, after WAP gateway receives Modify Qos Response, in user's signatory QoS information, upgrade the last QoS result of negotiation.
Step 418 after SGSN receives Delete PDP Context Response, sends the deexcitation PDP Context to MS and accepts response message Deactivate PDP Context Accept, user's failure of this time reaching the standard grade.
So far, the user reaches the standard grade and initiatively carries out the flow process end that QoS heavily consults by WAP gateway.Wherein, the flow process that QoS heavily consults is initiatively carried out for WAP gateway in step 407～418, and this QoS heavily consults may success, also may fail, and according to the difference of negotiation result, also difference to some extent of interactive signaling between MS, SGSN, GGSN and WAP gateway.Fig. 5 and Fig. 6 show the signaling process of initiatively consulting the QoS success and the signaling process of initiatively consulting the QoS failure respectively.
If above-mentioned user goes up in the line process, the user reaches the standard grade successfully, and then the user can carry out service access to SP by WAP gateway, specifically can carry out following steps:
Step 419, the user sends user's request to WAP gateway, consults successful QoS grade according to the last time of this user and provides access service for the user.
Step 420, WAP gateway asks to extract user ID according to the user, and searches the group identification of this user ID correspondence, when the forwarding user asks to SP, carries the group identification that finds.
Step 421, SP determines corresponding service content according to the group identification that sets in advance and the group identification of corresponding relation between service content and reception, and responds to WAP gateway, WAP gateway returns to MS after handling this response contents.
In this step, for different groups of users correspondences service content is set in advance among the SP, this service content can comprise displaying contents, charging policy etc.
In above-mentioned flow process, by in user profile and groups of users information, comprising qos-related information, WAP gateway can provide the access service of different brackets for the user in wireless side according to QoS information, and WAP gateway can initiatively initiate QoS and consult, with dynamic adjustment user's QoS grade.WAP gateway has been determined user's QoS grade, just determined to provide the priority of service for this user, so can be according to the QoS grade of different user, the service of high priority is provided for the user of high QoS grade, the preferential user who inserts high priority, and provide higher bandwidth for the user of high priority, the service of low priority is provided for the low user of low QoS grade, when system resource is nervous, the preferential user offline of forcing low priority, with free system resources, or provide limited bandwidth etc. for the low user of low priority.
In addition, in above-mentioned flow process, step 405 has been carried out two judgements, is respectively whether the QoS information of judging QoS information that request is carried and preservation mates and accord with Q oS scope whether; In fact, also can only carry out wherein any one judgement, in judged result when being, execution in step 406, in judged result for not the time, execution in step 407.
In above-mentioned flow process, user profile and groups of users information can be upgraded at any time, and the mode of obtaining user profile and groups of users information in the step 402 of concrete mode of upgrading and present embodiment is similar.Can upgrade by maintenance terminal, perhaps can when the user reaches the standard grade, upgrade to WAP gateway, perhaps also can utilize the interface with third party software to upgrade automatically by GGSN.
Present embodiment also provides a kind of WAP gateway, can be used to implement above-mentioned method flow shown in Figure 4.The concrete structure of this WAP gateway as shown in Figure 7, this WAP gateway is a kind of embodiment of WAP gateway shown in Figure 3.As shown in Figure 7, this WAP gateway specifically comprises: memory cell, processing unit, transmitting element, QoS negotiation element and information updating unit.By the contrast of Fig. 7 and Fig. 3 as seen, the WAP gateway in the present embodiment has further increased QoS negotiation element and information updating unit with respect to WAP gateway shown in Figure 3.Wherein, identical in the structure between memory cell, processing unit and transmitting element and function and the WAP gateway shown in Figure 3.Further, the function and the structure that possess further enhancing in the WAP gateway of present embodiment.Particularly,
Processing unit in the present embodiment, being further used for MS carries out in the context activation process, the charging request that sends from GGSN begins to extract the message user ID and the QoS information of carrying, and be index with this user ID, in the user profile that memory cell is preserved, search the group identification of this user ID correspondence and this user's signatory QoS information, be index with the group identification that finds again, in the groups of users information that memory cell is preserved, search signatory QoS scope, whether the QoS information that judgement is extracted from the message that GGSN sends mates with described signatory QoS information and signatory QoS scope, when not matching, specify a QoS grade to offer the QoS negotiation element according to described signatory QoS information and signatory QoS scope, notice QoS negotiation element is initiated QoS and is consulted.
The QoS negotiation element is used to receive the negotiation notice of described processing unit, and the QoS grade of the appointment that provides according to described processing unit, initiatively carries out QoS with GGSN, SGSN and MS with regard to the QoS grade of appointment and consults.
Information updating unit is used for described user profile and groups of users information that the real-time update memory cell is preserved.
In embodiment one, when being divided into different user group, the user carries out according to the operator under the user, in fact, also can divide according to other standard.The embodiment of the embodiment of the invention when illustrating according to QoS grade classification groups of users below by embodiment two.
Embodiment two:
Fig. 8 is for realizing WAP user is provided the method particular flow sheet of differentiated service in the embodiment of the invention two.As shown in Figure 8, this method comprises:
Step 801, the QoS grade in WAP gateway inside according to the user is divided into different groups of users with the user.
In the present embodiment, basic identical among user profile of preserving in the WAP gateway and groups of users information and the embodiment one, difference only is, comprises the QoS negotiation direction in the groups of users information.This QoS negotiation direction stipulates in this groups of users that carrying out when QoS consults be on the basis of the QoS grade of successfully consulting in the last time, indicates to increase the QoS grade and still reduce the QoS grade.
When carrying out the groups of users division, according to the QoS grade classification of the last success negotiation in the user profile.For example, can regulation QoS grade be that 1-3 and negotiation mode are that the user who increases belongs to groups of users 1, the QoS grade is that 4-6 and negotiation mode are that the user who increases belongs to groups of users 2, the QoS grade is that 1-3 and negotiation mode belong to groups of users 3 for the user who reduces, and the QoS grade is that 4-6 and negotiation mode belong to groups of users 4 for the user who reduces.
Step 802, in the last line process of user, the charging request that WAP gateway receives the GGSN transmission begins message, and extracts user ID and the QoS information that comprises in this message.
The operation of this step is identical with the step 403 of embodiment one, just repeats no more here.
Step 803, WAP gateway is according to the user ID of extracting, searching the group identification and the signatory QoS information of this user ID correspondence in user profile, is index with the group identification that finds again, searches the signatory QoS scope and the QoS negotiation direction of this group identification correspondence in groups of users information.
This user's who finds in QoS information that step 804, WAP gateway relatively comprise from the request that GGSN receives and the step 803 signatory QoS information judges whether the two mates, if then execution in step 805, otherwise, execution in step 806.
In this step, judge that mode that whether two kinds of QoS information mate can be identical with the mode in the step 405 of embodiment one.Perhaps, can further consider that also the QoS negotiation direction judges.Particularly, if the QoS information of carrying in the message does not meet the QoS negotiation direction with the last relation of consulting successful inter-stages such as QoS, judge that so the two does not match.
For example, it is 3 that the last time of writing down in the signatory QoS information of user is consulted successful QoS grade, and the QoS negotiation direction of this user place group is for reducing, if the QoS grade judges so that greater than 3 the QoS information of this request and the signatory QoS information of preservation do not match in the entrained QoS information of the message that WAP gateway receives.
Here, the negotiation direction that the reduction of QoS grade why can occur is to consider, when certain customers' credit rating is low, needs the situation with this user's QoS grade reduction.
Certainly, similar with the situation of previous embodiment one, this step also can only be carried out in above-mentioned two judgements, in the corresponding judgment result when being, execution in step 805, in the corresponding judgment result for not the time, execution in step 806.
Step 805 is utilized this user's of QoS information updating of this request signatory QoS information, and the user reaches the standard grade successfully.
In this step, after the signatory QoS information of upgrading the user, also the last time of monitoring user is consulted successful QoS grade at any time, determine under the user according to this QoS grade whether needs change groups of users, if desired, WAP gateway is consulted groups of users under the successful QoS grade adjustment user according to the last time of user automatically, specifically can adjust the pairing group identification of user ID in the user profile.
Step 806, WAP gateway is specified a QoS grade.
The step 407 of the mode of appointment QoS grade and embodiment one is similar in this step, difference is, when specifying the QoS grade, further to specify according to the QoS negotiation direction, the QoS grade of appointment and the last time of this user are consulted successful inter-stage accord with Q oS negotiation direction such as QoS.For example, be 3 if the last time of user is consulted successful QoS grade, the QoS negotiation direction is for reducing, and the QoS grade of appointment need be less than 3 so.
Step 807, WAP gateway is initiatively initiated heavily negotiations process of QoS with the QoS grade of this appointment, finishes heavily negotiations process of QoS jointly with GGSN, SGSN and MS.
Carry out in this step heavily to consult flow process identical with the described heavy negotiation flow process in step 407～418 of embodiment one, just repeat no more here.
If the user reaches the standard grade successfully, then the user can carry out service access to SP by WAP gateway, and identical in step 419～421 of concrete operations and embodiment one just repeats no more here.
In above-mentioned flow process, according to user's QoS grade classification groups of users, and WAP gateway can initiatively initiate QoS according to user's QoS information and consult, and with dynamic adjustment user's QoS grade, and then adjusts groups of users under the user.
Similar with the situation of embodiment one, in above-mentioned flow process, user profile and groups of users information also can be upgraded at any time, the concrete mode of upgrading can adopt the maintenance terminal that passes through described in the embodiment one to upgrade, perhaps can be when the user reaches the standard grade, upgrade to WAP gateway by GGSN, perhaps also can upgrade automatically according to the successful QoS information of the last negotiation of the user who self preserves by WAP gateway as previously mentioned.
In the foregoing description one and embodiment two, two kinds of modes of dividing groups of users have been adopted respectively, in fact, application also can combine two kinds of dividing mode, for example, at first carry out the division of one-level groups of users, carry out group of secondary user in the groups of users inside of this operator according to the QoS grade again and divide according to the operator under the user.
Being preferred embodiment of the present invention only below, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
