The embodiment of the present invention provides a kind of method of network selection, comprising:

It should be noted that above steps can be executed by user equipment.

First service provider priority list and second service provider priority list can be public Land mobile network PLMN priority list or organization unique identifier OUI(Organizationally Unique Identifier) priority list perhaps address field Realm priority list or for by PLMN mark, OUI mark and The priority list of at least two mark compositions in Realm mark.I.e. service provider can for PLMN perhaps OUT or Realm can also occur PLMN mark, Realm mark and OUI mark in first service provider priority list, altogether simultaneously With relatively priority orders.

Wherein, the default policy of the configuration is the strategy limited without location information and/or temporal information, i.e., in office What position and time are all effective strategy.

Further, after user equipment detects accessible Wireless LAN WLAN, can to the WLAN detected into The sequence of row major grade, obtains WLAN priority list.

It is described according to first service provider priority list or second service provider priority list from detection To WLAN in selection target network may include:

Successively detect whether the WLAN of priority from high to low in the WLAN priority list can access described first The service provider of priority from high to low in service provider's priority list, if detecting in the WLAN priority list WLAN can access the service provider in first service provider priority list, then select the WLAN for target Network；Alternatively,

That is, whether priority orders of the user equipment according to WLAN priority list, successively detect each WLAN It may be coupled to highest priority in first service provider priority list or second service provider priority list Service provider, if it is then the WLAN that can connect is final goal network.If current all WLAN can not be connected Into first service provider priority list or second service provider priority list, the service of highest priority is provided Quotient, then user equipment successively detects whether each WLAN may be coupled to further according to the priority orders of WLAN priority list The preferential high service provider of level in first service provider priority list or second service provider priority list. And so on, until finding suitable target network.The default policy of configuration strategy and configuration in the embodiment of the present invention can be with By ANDSF(Access Network Discovery and Selection Function, access network discovery and selection are serviced) Server or WLAN management entity are sent to user equipment.

Specifically, the default policy of the first service provider priority list defined according to available strategy and configuration Generating second service provider priority list includes:

Priority ranking is carried out to the WLAN detected in the embodiment of the present invention, WLAN priority list is obtained and specifically wraps It includes:

If there are home domain service providers preferably to indicate (WLAN HPLMN Priority in the available strategy Indication) and it is set as true, and there are the wlan network priority list (Home of home domain in the user equipment WLAN Specific Identifier List), then according to the wlan network priority list of the home domain to the detection The WLAN arrived carries out priority ranking, obtains WLAN priority list.

Further, if there are the wlan network priority list (User of user's control in the user equipment Controlled WLAN Specific Identifier List), then the wlan network according to the home domain is preferential After grade list is ranked up the WLAN detected further include:

Further, if there are the wlan network priority list (Operator of operator's control in the user equipment Controlled WLAN Specific Identifier List), then the wlan network according to the user's control is excellent After first grade list continues sequence to the WLAN detected further include:

The WLAN detected is continued to sort according to the wlan network priority list that the operator controls, In, priority of the WLAN that the wlan network priority list of operator's control defines in the WLAN priority list Priority inferior to the WLAN that the wlan network priority list of the user's control defines.

It should be noted that in embodiments of the present invention preferentially from the USIM(User Service of user equipment Identifier Module, User Service Identity Module) card in detect whether home domain wlan network priority list, User's control wlan network priority list or operator's control wlan network priority list, when not having in usim card When having above-mentioned each list, detect whether that there are the wlan network of home domain is excellent from the memory (UE memory) of user equipment The wlan network priority list of the wlan network priority list or operator's control of first grade list or user's control；

I.e. if thering is home domain service provider preferably to indicate in available strategy and being set as true, and home domain in UE memory Wlan network priority list it is available, then the wlan network in the list has a highest priority, in priority orders and UE It is consistent to deposit the priority orders that the wlan network priority list of middle home domain defines.Next user's control in processing UE memory Wlan network priority list, finally handle UE memory in operator control wlan network priority list, processing method It is carried out by described in above steps.

Further, if the method for network provided in an embodiment of the present invention selection can also include: in the available strategy There are home domain service providers preferably to indicate, is specifically as follows home domain public land mobile network and preferably indicates (WLAN HPLMN Priority Indication), and be set as true, then the home domain service of home domain service provider and equivalence mentions There is highest priority in first service provider priority list for quotient.

Further, if the method can also include: to be stored with pre-registered service in the user equipment to provide Quotient preferably indicates, is specifically as follows pre-registered PLMN and preferably indicates (WLAN Last Registered PLMN), then described The service provider of the pre-registered preferred demonstrative definition of service provider is in first service provider priority list Priority be only second to the priority of the home domain service provider and home domain service provider of equal value.

In addition, if preferably being indicated or the home domain service in the available strategy there is no home domain service provider Provider preferably indicates to be set to false as, then preferably indicates when being stored with pre-registered service provider in the user equipment When, the service provider of the pre-registered preferred demonstrative definition of service provider is in first service provider priority Highest priority in list, and the priority of home domain service provider and home domain service provider of equal value are only second to institute State the priority of the service provider of the preferred demonstrative definition of pre-registered service provider.

In addition, the method can further include: if the WLAN for being stored with user's control in the user equipment connects Fashionable service provider's priority list is specifically as follows the PLMN priority list when WLAN access of user's control (User Controlled PLMN Selector for WLAN access), then when the WLAN access of the user's control Priority of the service provider that service provider's priority list defines in first service provider priority list Inferior to the home domain service provider, home domain service provider of equal value and the pre-registered service provider are excellent Select the priority of the service provider of demonstrative definition.

Further, if the service provider being stored with when the WLAN access of operator's control in the user equipment is preferential Grade list is specifically as follows PLMN priority list (the Operator Controlled when WLAN access of operator's control PLMN Selector for WLAN access), then service provider's priority when the WLAN of operator's control is accessed Priority of the service provider that list defines in first service provider priority list is inferior to the user's control WLAN access when the priority of service provider that defines of service provider's priority list.

It should be noted that in embodiments of the present invention, preferentially having detected whether user from the usim card of user equipment Service provider when the WLAN access of service provider's priority list or operator's control when the WLAN access of control is excellent First grade list, if not having, in the same manner detect user equipment SIM(Subscriber Identity Module) card in With the presence or absence of relevant information.Whether if also not having in SIM card, detecting has available user's control in the memory of user equipment Service provider's priority list when WLAN is accessed connects if so, then continuing to sort to service provider by this priority list Get off, if the service provider's priority list being stored with when the WLAN access of operator's control in the memory of user equipment can With then continuing to sort to service provider by this priority orders, other service provider's priority can arbitrarily sort.

Specifically, shown in Figure 1, the method for network selection is mainly comprised the steps that

The accessible Wireless LAN WLAN of S101, detection；

After detecting accessible WLAN, priority ranking further can be carried out to the WLAN detected, to obtain WLAN priority list.The detection of WLAN can be obtained by detecting the network identity of WLAN in embodiments of the present invention, such as SSID(Service Set Identifier, service set identification), priority ranking then is carried out to the SSID of acquisition.

S102, user equipment current location information and/or temporal information are obtained, and by the location information and/or when Between information matched respectively with active position information defined in configuration strategy and/or effective time information, if matching at Function, then the strategy of successful match is available strategy；

If there is multiple available strategies, then priority is selected most according to the priority of available strategy (rule priority) High available strategy.

Active position information defined in configuration strategy may include at least one following factor: the position 3GPP, 3GPP2 (3rd Generation Partnership Project2, third generation partner program 2) position, WiMax(Worldwide Interperability for Microwave Access, worldwide interoperability for microwave accesses) position, WLAN location and physical bit It sets；Effective time information defined in the configuration strategy includes effective time Origin And Destination；

When the user equipment temporal information of acquisition was located within the scope of the effective time, then user equipment time for obtaining Information matches success.

Wherein, UE current location information can be obtained by reading system broadcast message, or the network by having connected It obtains.If UE has been already connected to 3GPP network at this time, then the station location marker of 3GPP network can be obtained by signaling message.This Outside, effective time can be indicated with time point and date.

It can be with multiple active position information and/or multiple effective time information, as long as user equipment obtains in each strategy Location information and/or temporal information and strategy in any one active position information and/or effective time information matches, The then current location information of the user equipment, and/or temporal information and strategy matching success.

It should be noted that only location information individually can be defined in configuration strategy, or temporal information is individually defined, or Person defines location information and temporal information simultaneously；When individually defining active position information in configuration strategy, user equipment is only needed Its current location information is obtained, current location information parameter and active position information parameter defined in configuration strategy are compared Compared with if there is at least one location information matches unanimously, then the strategy of successful match is available strategy.When single in configuration strategy When solely defining effective time information, user equipment need to only obtain current time information, will be in current time information and configuration strategy The effective time information of definition is matched, if current time within effective time, successful match, the plan of successful match It is slightly available strategy.When defining active position information and effective time information simultaneously in configuration strategy, user equipment is needed To obtain its current location information and current time information simultaneously, and respectively in configuration strategy active position information and effectively Temporal information is matched, and when location information and the equal successful match of temporal information, then the strategy of successful match is available strategy. Based on aforesaid way, user equipment searches configuration strategy and concentrates all strategies, defines significance bit including no in strategy The strategy of confidence breath and effective time information, is available strategy forever.

It further, include policy priority grade in the configuration strategy, which indicates each strategy of configuration Priority orders.When available strategy quantity is greater than one, policy priority grade can be used, multiple available strategies are compared Compared with selecting the strategy of highest priority finally to come into force strategy.

S103, the first service provider priority list that the available strategy defines is obtained, or according to described effective The first service provider priority list of policy definition and the default policy of configuration generate second service provider priority column Table；

S104, user equipment are arranged according to first service provider priority list or second service provider priority Table selection target network from the WLAN detected.

Specifically, user equipment can successively detect the WLAN of priority from high to low in the WLAN priority list is It is no to access the service provider of priority from high to low in first service provider priority list, if detecting institute The service provider that the WLAN in WLAN priority list can be accessed in first service provider priority list is stated, then Select the WLAN for target network；Alternatively,

That is, according to WLAN priority list sequence successively detect each WLAN whether may be coupled to it is described Priority is the service provider of i in first service provider priority list or second service provider priority list, WLAN may be coupled to the service provider that priority is i if it exists, then confirms that the WLAN is target access network；If it is not, Then i=i+1, return execute according to WLAN priority list sequence successively detect each WLAN whether may be coupled to it is described Priority is the service provider of i in first service provider priority list or second service provider priority list, Wherein, the i is that the smaller expression priority of value is bigger.

User equipment is raw according to the available strategy first service provider priority list defined and the default policy of configuration It can specifically include at second service provider priority list:

User equipment obtains third service provider's priority list from the default policy of configuration；

Specifically, user equipment can search the corresponding public land mobile network of WLAN detected Then PLMN carries out priority ranking to the PLMN found according to the default policy of configuration, provide to obtain third service Quotient's priority list, wherein user equipment can be by accessing network inquiry agreement (Access Network Query Protocol, abbreviation ANQP), or the corresponding public land mobile network of each WLAN is searched by authentication process PLMN；

The third service provider priority list is adjusted according to first service provider priority list It is whole, i.e., the priority orders of service provider in third service provider's priority list are adjusted, obtain second service Provider's priority list.Specifically, as shown in Fig. 2, (a) figure in Fig. 2 is that user equipment is obtained based on the default policy of configuration The PLMN priority relationship arrived, i.e. third service provider priority list, (b) figure in Fig. 2 is what available strategy defined PLMN priority relationship, i.e. first service provider priority list, the first service according to (c) figure in Fig. 2 in (b) figure Provider's priority list carries out PLMN priority orders to third service provider's priority list in (a) figure and adjusts to obtain Second service provider priority list, i.e., final PLMN priority relationship.

It should be noted that working as available strategy in the usim card of user equipment has " HPLMN Priority Indication " indicates and is set as true, then home-operator HPLMN(Home PLMN) and home-operator of equal value EHPLMN(Equivalent Home PLMN) there is highest priority.

Next, if " WLAN Last Registered PLMN " is available in usim card, " WLAN in usim card The PLMN priority that Last Registered PLMN " is defined is only second to home-operator HPLMN.If do not had in usim card " WLAN Last Registered PLMN " is then checked in UE storage card with the presence or absence of " WLAN Last Registered PLMN ", if it is present the PLMN priority that " WLAN Last Registered PLMN " is defined in UE storage card is only second to Home-operator PLMN.

If available strategy " WLAN HPLMN Priority Indication " is set to false as or does not have in usim card Above-mentioned instruction, then when " WLAN Last Registered PLMN " is available in usim card, " WLAN Last Registered The PLMN highest priority that PLMN " is defined.Otherwise, " WLAN Last Registered PLMN " is defined in UE storage card PLMN highest priority, followed by home-operator HPLMN, and home-operator EHPLMN of equal value.

Further, if there are available " User Controlled PLMN Selector in usim card PLMN priority list when the WLAN access of WLAN access ", i.e. user's control, then continued to arrange by this priority to PLMN Sequence, and the PLMN that the PLMN priority list when WLAN access of user's control defines is in the first PLMN priority list In priority it is preferential inferior to the PLMN of described HPLMN, EHPLMN and the preferred demonstrative definition of pre-registered PLMN Grade；

Further, if " the Operator Controlled PLMN Selector for that there is available strategy in usim card The PLMN priority orders that WLAN access " is defined are available, that is, there is the PLMN priority when WLAN access of operator's control List then is continued to sort by this priority to PLMN, and the PLMN priority column when WLAN access of operator control When priority of the PLMN that table defines in the first PLMN priority list is accessed inferior to the WLAN of the user's control The PLMN that PLMN priority list defines.
