101, access network equipment obtains the service access strategy of UE, and the service access strategy of the UE is according to ANDSF module It is obtained for the access network selection policies that UE is provided.

102, network is accessed according to the service selection that service access strategy is UE.

What needs to be explained here is that service access strategy can be radio access bearer (Radio Access Bear, letter Referred to as: the RAB) access strategy of rank, or the access strategy for UE rank.The service bearer of UE is on one or more RAB Network is accessed, for the access strategy of RAB rank, the mark of RAB is corresponding with service access strategy, the access for UE rank The mark of strategy, UE is corresponding with service access strategy.For the access strategy of RAB rank, the wireless access technology of multiple RAB (Radio Access Technology, referred to as are as follows: RAT) priority can be the same or different.Access for UE rank Strategy, the RAT priority for carrying whole RAB of UE business are all the same.The access strategy of UE rank primarily can be used for UE and not prop up Hold two or more network (such as third generation partner program (3^rdGeneration Partner Project, letter Referred to as: 3GPP) and WLAN (Wireless Local Area Networks, referred to as are as follows: WLAN)) simultaneous transmission when, Network side can not carry different RAB at different RAT priority.

Under a kind of embodiment, after 101, this method can also include: the mark for obtaining the corresponding RAB of service access strategy The mark of knowledge or UE；Then 102 may include: the mark or UE according to RAB mark, be UE service selection access net Network.

Specifically, service access strategy may include: the RAT priority of business, business allows to access and/or forbid to access Access-in point information；And/or business allows to access and/or forbid the temporal information of access；And/or business allow access and/ Or forbid the address information of access.It wherein, may include: the RAT priority of RAB for the access strategy of RAB rank, RAB permits Perhaps access and/or forbid the access-in point information of access；And/or RAB allows to access and/or forbid the temporal information of access；With/ Or, RAB allows to access and/or forbid the address information of access.Access strategy for UE rank may include: the RAT of UE excellent First grade, UE allow to access and/or forbid the access-in point information of access；And/or UE allows to access and/or forbid the time of access Information；And/or UE allows to access and/or forbid the address information of access.

For the access strategy of above-mentioned RAB rank, the corresponding ANDSF of business can be judged according to the business carried on RAB Strategy is sent to access network equipment according to the access strategy of strategy generating RAB rank, for example, it is assumed that ANDSF module is The access network selection strategy that UE is provided is the business for being 80 for port numbers, and network can be accessed by 3GPP technology, or WLAN technology accesses network, and preferentially accesses network using 3GPP technology.And CN judges that port numbers exist for 80 service bearer It is on the RAB of RAB ID=1, then above-mentioned to obtain the access strategy of RAB rank i.e. according to access network selection policies are as follows: RAB ID= The 3GPP technology that 1 RAB preferentially uses accesses network, secondly accesses network using WLAN technology.

For the access strategy of above-mentioned UE rank, the corresponding ANDSF of business can be judged according to all business that UE is carried Strategy is sent to access network equipment according to the access strategy of strategy generating UE rank, for example, it is assumed that ANDSF module is The access network selection strategy that UE is provided is the business for being 80 for port numbers, and network can be accessed by 3GPP technology, or WLAN technology accesses network, and preferentially accesses network using 3GPP technology.And CN judges that port numbers exist for 80 service bearer It is on some or the multiple RAB of the UE, then above-mentioned to obtain the service access strategy of UE i.e. according to access network selection policies are as follows: the UE Network preferentially is accessed using 3GPP technology, secondly accesses network using WLAN technology.

Fig. 5 is the selection method flow chart for the access network that the embodiment of the present invention four provides, as shown in figure 5, this method packet It includes:

501, UE obtains the information of access network selection policies and access network equipment that ANDSF module provides.

502, access network is determined according to the information of access network selection policies and access network equipment.

Specifically, in 501, the access network selection strategy that UE is obtained can be, but not limited to include: business RAT it is preferential Grade, RAT priority corresponding access network equipment load-threshold when coming into force.For example, the business for being 80 for port numbers, negative in RAN When load less than 60%, network can be accessed by 3GPP access technology or WLAN access technology, and preferentially use 3GPP access.For port numbers be 80 business, RAN load be greater than 60% when, can by 3GPP access technology, or Person's WLAN access technology accesses network, and is preferentially accessed using WLAN.

The information of access network equipment can be, but not limited to include two kinds, and one is the loads of access network equipment, and there are also a kind of It is the access tendency instruction of access network equipment.The access tendency instruction, refers to that access network equipment wishes which UE preferentially uses A access net transmission services, RAN can be judged according to the loading condition of itself, and provide corresponding access tendency instruction. For example, the load of RAN is higher, it is desirable to which UE preferentially uses the load of WLAN or RAN lower, it is desirable to which UE preferentially uses 3GPP.

UE can obtain the information of access network equipment in the following way: RAN is in broadcast control channel (Broadcast The information of the side RAN notified to whole UE by broadcast message on Control Channel, referred to as are as follows: BCCH)；Alternatively, RAN Pass through dedicated signaling for the side RAN on dedicated control channel (Dedicated Control Channel, referred to as are as follows: DCCH) Information notifies that particular UE, the UE refers to the UE for having reported and having supported WLAN relieving capacity.

Specifically, determining that access network can according to the information of access network selection policies and access network equipment in 502 To understand are as follows:

It, can be with according to the load determination of access network equipment if the information of access network equipment is the load of access network equipment Then the access network selection policies used determine the access net preferentially used according to the access network selection policies that can be used Network.For example, if 3GPP RAN load more than 60%, judges to select plan using corresponding access network according to the load information Slightly, indicate that UE preferentially uses WLAN at this time in strategy, then UE will do it WLAN access.If 3GPP RAN load is lower than 60%, Then judged to use corresponding access network selection policies according to the load information, indicate that UE preferentially uses 3GPP at this time in strategy, Then UE not will do it WLAN access.It should be noted that same or different preset percentage can be set in heterogeneous networks, this Place does not repeat them here.

If the information of access network equipment is the access tendency instruction of access network equipment, UE can select plan in access network In the network for slightly allowing to access, instruction selection access network is inclined to according to access.Access tendency instruction therein includes tendency UE Using WLAN, be inclined to UE using 3GPP, or do not interfere UE strategy etc..

For example, such as when ANDSF strategy is that UE for the business of port numbers 80 preferentially uses 3GPP, it is secondary to select WLAN.But this When network side access tendency instruction UE preferentially use WLAN, then UE can indicate preferential to attempt access according to the unloading of network side WLAN.If access tendency is designated as no tendency, according to ANDSF policy selection, if tendency indicates preferred 3GPP, even if ANDSF indicates that corresponding business 3GPP is low priority, and UE, which is still inclined to, transmits this business using 3GPP.

Networks, the access net such as concentration access WLAN or 3GPP are set when further UE is by access tendency instruction in order to prevent Standby information can also include the access factor.The effect of the access factor is: UE generates a random factor, random by this The factor and the access factor relatively decide whether to be inclined to instruction access according to access.Such as access the factor be 0.7, and UE generate with The machine factor is 0.6, since 0.6 < 0.7, UE is according to access instruction access, is generated again after otherwise postponing a period of time new random The factor.
