Fig. 2 is the flow chart of another embodiment of network method for handover control of the present invention.Compared with the embodiment shown in Fig. 1, this embodiment, between operation 130 and 140, also comprises:
210, PCRF equipment obtains the user of each user in specified network and to contract the traffic type information of class information and flow, the positional information of access base station and current temporal information, using the position of user's access base station as the position of user.
Wherein, the signing class information of user obtains from SPR; Comprise the access base station information of this user in the registration message of the user that P-GW reports, PCRF equipment can obtain the access base station of this user and the positional information stored as this user from registration message; The traffic type information that user uses is by being detected by P-GW during user's initiating business request and reporting PCRF equipment, and PCRF equipment can store; Current temporal information can be known by the clock information of PCRF equipment self.
220, PCRF equipment to be contracted class information, traffic type information, positional information and current temporal information by the user of each user respectively, judge whether that the flow of user needs to be switched to other network from specified network according to the network insertion got and switchover policy, such as, the need of by the flow of certain user from 4G network migration to 3G network.
If there is the flow of user to need to be switched to other network from specified network, perform the operation of 140.Otherwise, if do not have the flow of user to need to be switched to other network from specified network, do not perform the operation from 140.
The network insertion of the embodiment of the present invention and switchover policy have considered user and to have contracted the factors such as rank, type of service, position, time, for example, specified network is 4G network, user as lower in signing rank carries out point-to-point (P2P) service downloading at midnight, even if 4G network is busier, also this user is not carried out force handoff, because expection there will be no a large amount of users newly to access use this 4G network; But if by day, even if 4G network is not very busy, also this user to be switched, to ensure that the user that other signing ranks are higher accesses 4G network.And position-based, 3G network resource and the 4G Internet resources in each area are uneven, therefore the 3G network resource on A ground is more powerful, then user lower for how signing rank can be migrated to 3G network, and the 3G network resource on B ground is also deficienter, now as far as possible few user will be guided to 3G network, therefore the factors such as rank, type of service, position, time of contracting of the user in network insertion and switchover policy are mutually related, concrete tactful content can be set according to demand by operator, and can upgrade according to the change of resource and demand.

MME, after receiving the GTP-C message of this cause parameter value, can initiate user terminal separation process (UEdetachprocedure), this user to be disconnected from current network, guides it to access other networks.For the 3G network of CDMA, the flow process of the C.S0087 that network handover routines below can specify with reference to 3GPP2 standard, user is instructed to carry out, from LTE network to the switching strengthening HRPD (high rate packet data) (eHRPD) network, the flow of user being directed at the cdma network of relative free.
The network method for handover control of the various embodiments described above of the present invention can realize switching the network of networked users, and in addition, the embodiment of the present invention can also realize the access control of the user to request access specified network further.As shown in Figure 3, be the flow chart of another embodiment of network method for handover control of the present invention, this embodiment can realize the access control of the user to request access specified network, and it comprises:
310, when PCRF equipment receives the radio congestion information of the base station that P-GW reports, the radio congestion information that each base station that storage receives is up-to-date, specifically can be stored in and subscribe in configuration file thesaurus (SPR), also can be stored in private database.That is: if for a base station, in database, not yet store the radio congestion information of this base station, then directly store the primary wireless congestion information of this base station; If stored the radio congestion information of this base station before, be then updated to the radio congestion information of this base station that the last time receives.
The radio congestion information of the base station stored in database can be used as the reference data formulated network insertion and switchover policy or upgrade this strategy.
320, P-GW receives user (for ease of distinguishing, hereinafter referred to as: request access user) request access specified network network insertion request time, initiate credit control request (CCR) message to PCRF equipment, this CCR message comprises the request user ID of access user and the access base station information of this request access user.
330, PCRF equipment obtains in CCR message asks the user of access user to contract class information, the position of access base station and radio congestion information and current temporal information, and in CCR message, the position of access base station is as the position of request access user.
340, the congestion severity that in PCRF equipment acquisition CCR message, the radio congestion information of access base station is corresponding, and obtain network insertion corresponding to this congestion severity and switchover policy, according to network insertion and the switchover policy of this correspondence, ask the user of access user to contract rank and position, current time, judge whether to allow this request access user to access specified network.
If allow request access user access specified network, perform the operation of 350.Otherwise, if do not allow request access user access specified network, perform the operation of 360.
350, PCRF equipment returns diameter credit control response (CreditControlAnswer, the CCA) message allowing access specified network to P-GW.
Afterwards, the follow-up flow process of the present embodiment is not performed.
360, PCRF equipment returns the CCA message of refusal access specified network to P-GW.
The AVP value of the object code (Result-Code) wherein refused in the CCA message of access specified network is the refusal access value of expansion.
According to 3GPP standard regulation, CCA message comprises the AVP of this line of result-code, and the AVP value comprised is defined in RFC3588, and in general AVP value and implication thereof comprise several as follows:
-1xxx(Informational)；
-2xxx(Success)；
