Abstract
The method includes following steps: a) sets a access point name(APN) in home location register (HLR) for each 3G user; the APN is not included in the subscription data of all 2G users; b) after the user sends an attach request to SGSN, the HLR returns a response message carrying the subscription data information; c) SGSN decides if the specific APN is existed in the subscription data; if yes, then confirms the user is one of 3G users, and enters next step; otherwise, decides if the access network of user is 2G radio network or 3G radio network; if it a 2G radio network, then enters next step; if it is a 3G network, the SGSN sends message of refusing the attach to the user to refuse the attach request.
Description
Technical field
The present invention relates to moving communicating field, relate in particular to the method for a kind of 2G of differentiation, 3G subscription.
Background technology
At present, the GPRS network that is applied to high speed Internet access has obtained extensive commercialization, and the flank speed of its transmission data has reached 115kbit/s.WCDMA 3-G (Generation Three mobile communication system) (3G) seamlessly transits through gprs system from gsm mobile communication system and forms, and it realizes that commercialization is also within sight.After mobile operator provided the WCDMA service, mobile operator will provide GPRS and WCDMA two kinds of services in long period of time, consult network architecture shown in Figure 1.
Because WCDMA 3-G (Generation Three mobile communication system) (3G) network quality is significantly better than second generation mobile communication system (2G), and the business that provides is abundanter, 2G user and 3G subscription must be offered an explanation out at core net node by operator, reach the purpose of having only 3G subscription could use 3G network, thereby attract more 2G user to turn to 3G subscription.
Existing GSM/GPRS user will be upgraded to WCDMA user, user's mobile phone will need be upgraded to the WCDMA mobile phone from the GSM/GPRS mobile phone, and user's SIM card is upgraded to usim card.In prior protocols, be not the signatory special sign of 3G subscription or 2G user.SGSN can judge that this user is 2G user or 3G subscription by judge the authentication collection get from HLR: if operator is certain user authentication 5 tuples of having contracted in HLR, then SGSN thinks that this user is a 3G subscription; If operator for certain user in HLR authentication 3 tuples of having contracted, then SGSN thinks that this user is 2G user.User when an only signatory GSM/GPRS business changes the WCDMA mobile phone into and is linked on the WCDMA network, and when attempting to use WCDMA professional, SGSN can be 3 tuples by the authorization data of judging this user, and refuses adhering to of this user.
In actual use, some operator is owing to a variety of causes, and the SIM card of can't upgrading is a usim card, and all 3G subscriptions all use original SIM card, and the authentication collection also is 3 original tuples.In this case, after the user of an only signatory 2G has changed 3G mobile, also can be linked in the 3G network, at this moment, SGSN can't know that this user is 2G user or 3G subscription.
Summary of the invention
The present invention is by being that 3G subscription is set a special APN at HLR, and with difference 2G user and 3G subscription, and refusal 2G user uses the 3G service.
Technical scheme of the present invention is:
A kind of method of distinguishing 2G user and 3G subscription may further comprise the steps:
A: for each 3G subscription the part of one specific APN (APN) as subscription data is set all in HLR (attaching position register), this specific APN is not included in all 2G users' the subscription data;
B: the user is after SGSN (service support node) sends Attach Request message, and SGSN sends location update request message to HLR, and HLR carries user contracting data information to SGSN echo reply message in this message;
C:SGSN analyzes in the subscription data that returns whether have this specific APN, if judge that then this user is 3G subscription, carries out the follow-up flow process that continues of 3G subscription; Otherwise, judge that this user is 2G user, and carry out the following step;
D:SGSN judges that further this user's Access Network is 2G wireless access network or 3G wireless access network, if the 2G wireless access network then carries out 2G user's the follow-up flow process that continues; Adhere to refuse information if 3G wireless access network, SGSN send to this user, refuse this user and adhere to request.
Described specific APN is any a string character string.
Described specific APN does not activate as PDP and uses.
Among the described step D, if user's Attach Request message is from BSC (base station controller), then SGSN judges that this user inserts from the 2G wireless network; If user's Attach Request message is from RNC (radio network controller), then SGSN judges that the user inserts from the 3G wireless network.
A kind of method of distinguishing 2G user and 3G subscription may further comprise the steps:
A: for each 3G subscription the part of one specific APN (APN) as subscription data is set all in HLR (attaching position register), this specific APN is not included in all 2G users' the subscription data;
B: the user is after SGSN sends the routing update request, and SGSN sends location update request message to HLR, and HLR carries user contracting data information to SGSN echo reply message in this message;
C:SGSN analyzes in the subscription data that returns whether have this specific APN, if judge that then this user is 3G subscription, carries out the follow-up flow process that continues of 3G subscription; Otherwise, judge that this user is 2G user, and carry out the following step;
D:SGSN judges that further this user's Access Network is 2G wireless access network or 3G wireless access network, if the 2G wireless access network then carries out 2G user's the follow-up flow process that continues; If the 3G wireless access network, SGSN sends the routing update refuse information to this user, refuses this user's routing update request.
Described specific APN is any a string character string.
Described specific APN does not activate as PDP and uses.
In the described steps d, if user's routing update request message is from BSC, then SGSN judges that the user inserts from the 2G wireless network; If user's routing update request message is from RNC, then SGSN judges that the user inserts from the 3G wireless network.
By using method of the present invention, the HLR that need not upgrade can reach the purpose of distinguishing 2G and 3G subscription.

Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
The significant data that uses when APN activates as PDP is preserved as the part in the subscription data in HLR, and HLR can preserve a plurality of APN for each user.Each user 50 PDP static contexts of can in HLR, contracting, each PDP static context comprises an APN, and at present, China Mobile is 2G user 2 APN that contracted, corresponding different respectively business.One is CMWAP, is by GPRS visit WAP business; Another is CMNET, is meant the service except WAP, such as connecting internet etc.
The present invention is by being provided with the part of a specific APN as subscription data for 3G subscription, this specific APN is not included in all 2G users' the subscription data, and this APN does not use for activating.Therefore, in the activation process of SGSN process user, SGSN knows this APN as just a sign distinguishing 2G, 3G, rather than the APN that uses when activating.This APN can be an arbitrary string.It is the special APN of the signatory sign of 3G subscription 3GCMNET as differentiation 2G user that present embodiment passes through, and this APN does not use as activation.
The course of work of attachment flow is described below in conjunction with Fig. 2:
When the user after SGSN sends Attach Request message, SGSN is by upgrading position message informing HLR, HLR carries user contracting data information to SGSN echo reply message in this message.
SGSN analyzes the subscription data that returns, and has judged whether this distinctive mark 3GCMNET, if there is this sign, judges that then this user is 3G subscription, otherwise judges that this user is 2G user;
If SGSN judges this user and is 3G subscription, then handles according to 3G subscription;
If judging this user is 2G user, SGSN judges user's access network type, and from BSC, then SGSN judges that the user inserts from the 2G wireless network, then continues to handle this user's attachment flow according to 2G user as user profile; From RNC, then SGSN judges that the user inserts from the 3G wireless network as user profile, and adheres to refuse information to this user's transmission, and message content is " not allowing to insert in this lane place ", thereby refuses the service that this user uses 3G.
Except attachment flow, in the Routing Area Update flow process between SGSN, new side SGSN also needs subscription data is analyzed, thereby distinguishes 2G user and 3G subscription.
For 3G subscription is provided with under this special APN situation, be 3GCMNET in this example in HLR, as shown in Figure 3, concrete handling process is:
When the user after SGSN sends the routing update request message, SGSN is by upgrading position message informing HLR, HLR carries user contracting data information to SGSN echo reply message in this message.
SGSN analyzes the subscription data that returns, and judges whether this has this distinctive mark 3GCMNET, if there is this sign, judges that then this user is 3G subscription, otherwise judges that this user is 2G user;
If SGSN judges this user and is 3G subscription, then handles according to 3G subscription;
If judging this user is 2G user, SGSN judges user's access network type, and from BSC, then SGSN judges that the user inserts from the 2G wireless network, and continues to handle this user's routing update flow process according to 2G user as user profile; From RNC, then SGSN judges that the user inserts from the 3G wireless network as user profile, and adheres to refuse information to this user's transmission, and message content is " not allowing to roam into this lane place ", thereby refuses the service that this user uses 3G.
The present invention HLR that need not upgrade only need be for 3G subscription be provided with a special APN in HLR, and SGSN is by the judgement to APN, thereby 2G user is distinguished with 3G subscription, and refuses 2G user and insert from 3G network, and then the service of enjoyment 3G network.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
