Abbreviation PS), therefore it is properly termed as the 3GPP packet-switched domain (Evolved3GPP Packet Switched Domain) of evolution,
The alternatively referred to as grouping system (Evolved Packet System, abbreviation EPS) of evolution.New 3GPP core network
(Evolved Packet Core Network, abbreviation EPC) not only supports 3GPP access technology, and the General Mobile such as evolution is logical
Believe System Terrestial wireless access network (Evolved UMTS Terrestrial Radio Access Network, abbreviation E-
UTRAN), Universal Mobile Communication System land radio access web (UMTS Terrestrial Radio Access Network,
Abbreviation UTRAN), GSM EDGE Radio Access Network (GSM EDGE Radio Access Network, GERAN), while supporting non-
3GPP access technology, such as CDMA2000(Code Division Multiple Access2000), global microblogging interconnection access
(Worldwide Interoperability for Microwave Access, abbreviation WIMAX), WLAN
(Wireless Local Area Networks, abbreviation WLAN).Particularly with the user equipment for supporting a variety of access technologies
(User Equipment, abbreviation UE), UE can carry out initial network selection by the network selection strategy configured.Meanwhile network side
It can also be by WLAN management entity (Interworking-WLAN Management Object, abbreviation WLAN MO) to UE's
Initial network selection strategy is modified, i.e., the network selection strategy of transmission user's granularity is to user equipment, so that user equipment be instructed to select
Suitable access net.
Existing WLAN (Wireless Local Area Networks, Wireless LAN), obtains around scanning input
Wlan network is taken to identify, such as service set (Service Set Identifier, abbreviation SSID).User equipment is based on operation
The configuration of quotient or the selection of user obtain wlan network and identify priority list.User equipment by the wlan network scanned according to
Wlan network priority list (i.e. SSID priority list) is ranked up, and is started to query from the wlan network of highest priority
Public land mobile network (Public Land Mobile Network, abbreviation PLMN) corresponding to it, then, user equipment
Configuration based on operator obtains static service provider's priority list, this service provider's priority list static storage
In a user device, it and can be modified by WLAN MO to it.Priority list of the user equipment based on SSID is successively inquired
Whether the wlan network of surrounding may be coupled to the PLMN of highest priority.If it is then using this wlan network as final
Target network.Otherwise the high PLMN network of preferential level is searched based on SSID priority orders, until finding suitable target
Access net.
In the research and practice process to the method, it was found by the inventors of the present invention that the service that user equipment obtains mentions
It is that operator configures the static information on UE for quotient's priority list, although operator can carry out it by WLAN MO
Modification, but the mode modified is that new service provider's priority list replaces old service provider's priority list, that is, is appointed
Anticipate the moment on UE there is only unique device provider priority list, and this list will not with UE position is mobile or the time
Change and changes.
With the continuous upgrading that wlan network is disposed, the roaming relationships between operator also become increasingly complex.For example it runs
There are roaming relationships by quotient A and operator B and operator C, and operator A thinks that the network of operator B is better than the net of operator C
Network, therefore in service provider's priority list of its setting, the PLMN B priority of operator B is higher than operator C's
PLMN C.But network of the network deployment scenario of operator C than operator B disposes feelings in certain special areas, such as region X
Condition will be got well.Therefore the network that its user data is routed to operator C is preferred in region X, operator A.But based on quiet at present
The unique PLMN priority relationship of state is unable to satisfy the demand.
