Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not paid belongs to the scope of protection of the invention.
The network architecture and business scenario of description of the embodiment of the present invention are for the technical scheme of the more clear explanation embodiment of the present invention, the restriction for technical scheme provided in an embodiment of the present invention is not constituted, those of ordinary skill in the art understand, with the differentiation and the appearance of new business scene of the network architecture, technical scheme provided in an embodiment of the present invention is equally applicable for similar technical problem.
Illustrated below exemplified by disposing scene of the 2/3G networks with 4G networks simultaneously.
Fig. 1 is a kind of while disposing the network architecture schematic diagram of 2/3G networks and 4G networks.In order to make it easy to understand, the network architecture illustrate only the base station equipment BSC and BTS, the base station equipment RNC of 3G network and NodeB, 4G network of mobile management net element MME, HSS, HLR, 2G network of mobile management net element SGSN, 4G network of 2/3 network base station equipment eNodeB and user equipment (UE).It will be understood by those skilled in the art that the network element and the network architecture in actual deployment can be different.Those skilled in the art should know that the above-mentioned network architecture is only a kind of citing of application scenarios of the embodiment of the present invention, exemplary, can also apply in 2G networks and the concurrently deployed scene of 4G networks, or 3G network and the concurrently deployed scene of 4G networks.
As shown in Figure 1：
SGSN is connected as the mobile management net element of 2/3G networks with the base station equipment BSC and/or RNC of 2/3G networks, and is connected with the HLR of the user contracting data for the 2/3G networks that are stored with.HSS is connected with the mobile management net element MME of 4G networks.Be stored with the user contracting datas of 4G networks in HSS.In the design of the present invention, SGSN and MME are interconnected, and UE 4G network contraction data are inquired about by MME to HSS.In another design of the present invention, SGSN directly interconnects inquiry UE 4G network contraction data with HSS.In another design of the present invention, HLR and HSS is interconnected, and SGSN inquires about UE 4G network contraction data by HLR to HSS.
MME is connected as the mobile management net element of 4G networks with the base station equipment eNodeB of 4G networks, and is connected with the HSS of the subscription data of the user for the 4G networks that are stored with.
It will be understood by those skilled in the art that SGSN and MME can be disposed individually on different devices, it can also close and be located in same equipment, not repeat herein.
UE can support 2/3G networks and 4G networks, that is, support the base station with 2/3G networks, and the base station of 4G networks to carry out radio communication.In actual cordless communication network, there is substantial amounts of UE, be shown here only a UE as example.It will be understood by those skilled in the art that with the development of technology, the base station of 2/3G networks and the base station of 4G networks, may be physically the equipment of separation, can also close and be located in same equipment.
HLR is used for the subscription data for storing the corresponding 2/3G networks of the UE.When the user of the UE carries out business with mobile operator signing 2G networks, the subscription data that the UE corresponds to 2G networks can be stored in HLR, shows that the UE can access 2G networks and carry out business.Equally, when the user of the UE carries out business with mobile operator signing 3G networks, HLR can store the subscription data that the UE corresponds to 3G network.
HSS is used for the subscription data for storing the corresponding 4G networks of the UE.When the user of the UE carries out business with mobile operator signing 4G networks, HSS can store the subscription data that the UE corresponds to 4G networks.Accordingly, for example when the subscription data of 4G networks is not present in HSS, the request of UE access 4G networks can be rejected.
For the ease of narration, UE user 2G, 3G or 4G network of having contracted may also be referred to as the UE and contract 2G, 3G or 4G network.
At the same time under the scene of deployment 2/3G networks and 4G networks, the overlay area of 2/3G networks and 4G networks has overlapping.The UE in an overlapping coverage area, can carry out radio communication with the base station of any one in BTS, NodeB or eNodeB.
Due to 4G network providers with exist soon, in network it is substantial amounts of can support the UE of 2/3G networks and 4G networks, the 2/3G networks but these UE user only may contract with operator, 4G networks of not contracting.After these UE access 2/3G networks, because these UE support 4G networks, the base station equipment of 2/3G networks can preferably be linked into 4G networks for above-mentioned UE.But it is due to that these UE do not contract 4G networks, can be refused to access by 4G networks, these subsequent UE can access 2/3G networks again.Again after access 2/3G networks, these UE can be preferably linked into 4G networks by the base station equipment of 2/3G networks again, cause these UE frequent switchings between 2/3G networks and 4G networks, produce ping-pong phenomenon, and punching is caused to network
Hit, cause business unstable.
In order to solve the above problems, it may be considered that when UE accesses 2/3G networks, introduce anticipation mechanism, just prejudge whether UE can access 4G networks when UE accesses 2/3G networks in advance.For example, judge whether UE allows to access 4G networks by the mobile management net element of 2/3G networks when 2/3G networks can be resided in UE, and in the case where the UE does not allow access 4G networks, the base station for notifying 2/3G networks is not the preferred 4G network insertions of the UE, so as to avoid the UE from continuing to switch between 2/3G networks and 4G networks, service stability is improved.In addition, for that can also not set a term of validity for the UE operations for preferably accessing 4G networks, i.e., after more than the term of validity, the base station of 2/3G networks can revert to the UE and preferably access 4G networks again, it is easy to the user of the UE Yi Dan with after operator's signing 4G networks, can preferably access 4G networks.
As one of implementation, can with by whether can successfully obtain the subscription data of the corresponding 4G networks of the UE determine whether the UE access 4G networks.It is exemplary, it may be considered that the subscription data of the corresponding 4G networks of the UE is obtained by SGSN and HSS interaction requests, if obtaining failure, can determine that the UE does not allow to access 4G networks.
According to above-mentioned analysis, in the scheme of the offer of the embodiment of the present invention：
When the mobile management net element of first network knows that user equipment requests access first network, the subscription data of the mobile management net element acquisition request user equipment in the second network；When the mobile management net element obtains subscription data failure, the mobile management net element sends failure configured information to the base station equipment of the first network, and the failure configured information is used to indicate not select second network insertion for the user equipment.
For the technical scheme of the clearer explanation embodiment of the present invention, illustrated below with reference to the network architecture shown in Fig. 1.
Using 4G networks as LTE network in the embodiment of the present invention, 2G networks be GPRS network, 3G network be UMTS network exemplified by illustrate.
Exemplary, Fig. 2 shows a kind of schematic flow sheet of cut-in method.Above-mentioned anticipation mechanism is introduced in cut-in method shown in Fig. 2, in Fig. 2 citing, the UE does not contract 4G networks, therefore in HSS and in the absence of the subscription data of the corresponding 4G networks of the UE.
As shown in Figure 2：101st, UE sends access request by BSC or RNC to SGSN.
Wherein, the access request is used to ask to access the corresponding 2/3G networks of the SGSN.Here, request, which accesses the corresponding 2/3G networks of the SGSN, can do the understanding of broad sense, i.e., it can be appreciated that request continues to reside in the corresponding 2/3G networks of the SGSN.
Exemplary, the access request can include attach request (English：Attach request), or Routing Area Update (English：Routing area update request, abbreviation RAU) request.
Exemplary, the UE performs step 101 after can starting shooting, and can also perform step 101 when needing from other network switchings to 2/3G networks, can also perform step 101 after UE access 2/3G networks.
By step 101, SGSN knows that UE selection 2/3G networks are that its resident network, i.e. SGSN know UE request access 2/3G networks.After step 101, SGSN can perform above-mentioned anticipation mechanism, to determine whether the UE allows to access 4G networks.
Step 103-104 realizes for a kind of of above-mentioned anticipation mechanism.
103rd, SGSN is sent to HSS updates location request message.
Wherein, SGSN by the location update request message come the acquisition request UE 4G networks subscription data.
Exemplary, UE UE ID (Chinese can be included in the more new position request：Mark, English：Identity) to indicate to obtain the subscription data of the corresponding UE of UE ID in 4G networks.
104th, HSS is sent to SGSN updates position response message.
It is exemplary, because the UE does not contract 4G networks, the subscription data of the corresponding 4G networks of the UE will not be carried in the renewal position response.
Optionally, because the UE does not contract 4G networks, configured information can be carried in the renewal position response, for indicating that the subscription data of the corresponding 4G networks of the UE can not be obtained, it is understood that be the subscription data in the absence of the corresponding 4G networks of the UE.Exemplary, the configured information can be realized by result cells, when result cell values are:
DIAMETER_ERROR_USER_UNKNOWN(5001)、
DIAMETER_ERROR_UNKNOWN_EPS_SUBSCRIPTION(5420)、
DIAMETER_ERROR_RAT_NOT_ALLOWED (5421) or
Represent to obtain during DIAMETER_ERROR_ROAMING_NOT_ALLOWED (5004)
The subscription data of the corresponding 4G networks of the UE.
According to above-mentioned renewal position response message, SGSN can confirm that the subscription data failure for obtaining UE in 4G networks.
Optionally, SGSN can multiple subscription data of the acquisition request UE in 4G networks, i.e. when SGSN after step 103 is with 104 does not get the subscription data of the corresponding 4G networks of the UE, it can attempt to obtain subscription data of the UE in 4G networks again by step 103 and 104.It can so avoid because other reasonses cause that subscription data of the UE in 4G networks can not be obtained, for example：The reasons such as connection temporarily interruption or HSS overloads between SGSN and HSS.
It is appreciated that in the case where UE does not contract 4G networks, SGSN can be caused to obtain the UE and failed in the subscription data of 4G networks, that is, represent not allowing the UE to access 4G networks.
Optionally, before step 103-104, SGSN can also first determine the ability whether UE has access 4G networks.Exemplary, the MS network capability (English that can be reported according to the UE：Mobile station network capability) evolution in field packet-based core networks ability (English：Evolved packet core capabiltiy) parameter judge the UE whether have access 4G networks ability.For example, the packet-based core networks ability parameter of the evolution of the UE is its ability with access 4G networks of 1 expression, it is its ability without access 4G networks of 0 expression.It is to be appreciated that, for the user equipment of the ability without access 4G networks, the user equipment will not communicate with the base station equipment of 4G networks, therefore not result in the frequently switching between 2/3G networks and 4G networks, it may not be necessary to perform step 103-104.It will be understood by those skilled in the art that for the facility on realizing, even for the user equipment without access 4G network capabilities, step 103-104 can also be performed.
Because SGSN obtains the subscription data failure of the corresponding 4G networks of the UE in step 103-104, it is contemplated that indicating BSC or RNC not by the UE priority access 4G networks, it can so avoid UE is lasting from switching between 2/3G networks and 4G networks, the pressure of network is alleviated, the stability of holding business is also beneficial to.
It is used as a kind of optional implementation, it may be considered that by the mobile management net element of 2/3G networks, i.e. SGSN, sends failure configured information to indicate 2/3G base station equipment no longer by the UE priority access 4G networks.For example：
108th, SGSN sends failure configured information to BSC/RNC.
Wherein, the failure configured information is used to indicate BSC/RNC not by the UE priority access 4G networks.After BSC/RNC receives the failure configured information, BSC/RNC will not select 4G network insertions for the UE.Those skilled in the art are, it should be understood that the statement of information indicated by the failure configured information can have a variety of, such as：Forbid as the UE prioritizing selection 4G network insertions, stop the UE priority access 4G networks, the invention is not limited in this regard.
Those skilled in the art are, it should be understood that SGSN can send the failure configured information to BSC/RNC by downstream message.Wherein, downstream message includes one or more of following citing message.
Exemplary, the mobile management net element of 2/3G networks can pass through RAB assignment request (English：Rab assignment request) message or redirect request (English：Relocation request) message sends the failure configured information to RNC." handover to E-UTRAN shall not be performed " represent the failure configured information wherein it is possible to the value of the E-UTRANservice handover cells in this two message is set to.
