In addition; whether the embodiment of the present invention is also configured with the node protected network selection policies trigger condition and preferred network or preferred network type, allow user to carry out the change of network selection policies trigger condition and preferred network or preferred network type to indicate ME.
The method that above-mentioned network is selected, provide the implementation method of the type of network selection policies and the data structure of network selection policies, and the network selecting method of selection strategy Network Based, the control that network is selected can be more flexible, make terminal can localizing objects network faster, that reduces that network selects be consuming time simultaneously.
The embodiment of the present invention two is introduced the method for carrying out network selection according to network selection policies.In embodiment two, network side can set some network selection policies more efficiently to carry out network selection, and these network selection policies can be divided into trigger condition and preferred network (or preferred network type).
Wherein, trigger condition can for business (or type of service) triggering, network QoS triggering, the triggering of available network operating condition, signal quality triggering, location triggered, environmental triggers and prevent in several trigger conditions such as service disconnection instruction one or more.
Realize the data structure of network selection policies as shown in Figure 9, this data structure can be configured as a part of MO or MO and be kept on the device management tree of terminal, business (or type of service) triggering in this trigger condition, network QoS triggering, signal quality triggering, location triggered, environmental triggers and prevent service disconnection indicate one or more can be selected as required to carry out structural rearrangement, new trigger condition can also be added as required and carry out structural rearrangement.
In this data structure,
ServiceTrigger is that business (or type of service) triggers, and can comprise multiple business or type of service under it, wherein,
The a certain specific transactions that ServiceTrigger/<X>/Service node instruction trigger network is selected, as downloading service, or a certain particular traffic type, as the 4 class types of service that 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) defines for QoS.When ME starts this business, or when the business that starts of ME belongs to above-mentioned type of service, then trigger network is selected.
ServiceTrigger/<X>/PreferedLi st node and child node thereof configure preferred network corresponding to this condition (NetworkID), preferred network type (NetworkType) and priority (Priority) thereof.Wherein the value of preferred network type comprises: WLAN, WiMAX, 3GPP2 (3rd Generation Partnership Project 2,3rd Generation Partnership Project two), GPRS (General Packet Radio Service, GPRS) etc., wherein the priority of multiple preferred network or preferred network type can be identical.If the priority of multiple preferred network or preferred network type is identical, then illustrate that this business can select one in the identical network of priority access or select multiple network to carry out accessing (that is: business inter-network) simultaneously.
Whether ServiceTrigger/<X>/Enabled node is effective for controlling this network selection policies.Do not occur if its value is True (very) or this node, then ME thinks that this network selection policies is effective, if its value is F alse (vacation), then ME thinks that this network selection policies is invalid.Enabled node effect in following trigger condition and value and this node similar, repeat no more.
NetQoSTrigger is that network QoS triggers, the QoS of heterogeneous networks layer definition is different, here QoS refers to network QoS, child node NetQoSTrigger/<X>/NetworkID under it indicates a certain particular network, NetQoSTrigger/<X>/MinQoS is the minimum QoS demand of this particular network, the parameter of QoS has multiple, be configured on NetQoSTrigger/<X>/MinQoS/* node, concrete parameter is see the standard definition of corresponding network.ME is when determining this particular network as present access network, if current network QoS lower than minimum QoS demand (in qos parameter system a certain parameter lower than correspondence MinQoS * node institute Configuration Values, think that current network QoS is lower than minimum QoS demand), then trigger network is selected, preferred network is not had under this node, the network selection list then after trigger network is selected, ME reading UICC stored carries out network selection, or the network selection list that the device management tree of reading UICC and ME stores carries out network selection.
OpTrigger is that available network operating condition triggers, its child node OpTrigger/<X>/NetworkID is network identity, indicate a certain particular network, OpTrigger/<X>/OpCondition is the certain operations condition of this particular network definition, the i.e. service condition of the network of Virtual network operator definition, such as: error condition.This operating condition can have multiple, concrete conditional definition is in OpTrigger/<X>/OpCondition/* node, ME is when determining this particular network as present access network, if there is this condition, trigger network is selected, preferred network is not had under this node, then after trigger network is selected, ME reads the network selection list that UICC stores and carries out network selection, or reads the network selection list that the device management tree of network selection list that UICC stores and ME stores and carry out network selection.
SingalTrgger is that signal quality triggers, its child node SingalTrgger/<X>/NetworkID is network identity, indicate a certain particular network, SingalTrgger/<X>/MinValue is the lowest signal qualities that this network allows, and SingalTrgger/<X>/Timer is the duration.ME is when determining this particular network as present access network, if current network signal quality is lower than lowest signal qualities, and after continue for the Timer node indication time, then trigger network is selected, preferred network is not had under this node, then after trigger network is selected, ME reads the network selection list that UICC stores and carries out network selection, or reads the network selection list that the device management tree of network selection list that UICC stores and ME stores and carry out network selection.In addition, the no signal in triggering to prevent event, with the conflict of this trigger condition, triggers process when there is the situation of network no signal as event.
LocationTrigger is location triggered, its child node LocationTrigger/<X>/B SID is Base Station Identification, indicate a certain base station, after ME enters this base station range, then trigger network is selected, preferred network is not had under this node, then after trigger network is selected, ME reads the network selection list that UICC stores and carries out network selection, or reads the network selection list that the device management tree of network selection list that UICC stores and ME stores and carry out network selection.
ContextTrigger is environmental triggers, its child node ContextTrigger/<X>/ScanSwitch ID is a certain network identity, this network selection policies instruction ME scans and accesses this mark indication network, that is: ME scans this mark indication network, and this indication network can be WLAN.Preferably, ME carries out periodic scanning to this mark indication network, and after ME scans this network, ME judges that the conditions such as signal quality attempt to access this network after meeting access, therefore this child node had both been the trigger condition of this network of scanning, was again the indication information that instruction ME accesses this network simultaneously.
InterruptService indicates for preventing service disconnection, and when the value of this node is True, ME had judged whether that business used before trigger network is selected.If there is business to use, then judge when network is selected that network switches and whether can cause service disconnection (that is: this business in current network and be switched between network whether have business continuity ability), if determine that network switching can cause service disconnection, then stop network and switch.Do not occur if the value of this node is False or this node, then ME carries out normal network switching.Network side only tells whether ME allows interrupt network to select in this process, specifically judges which network switches and which service disconnection may be caused to be determined by ME.
In order to protect above-mentioned network selection policies by unauthorized update, in this data structure, have also been devised UserModiNSPolicy node.Network side is controlled the network selection policies whether user can revise network side setting by this node, be specially: if this nodal value is True, then user can be modified to these network selection policies by the user interface of ME, if this nodal value is False, then user can not modify to these network selection policies.
In order to network side is selected to control to the automatic network selection of ME and the manual network of user flexibly, two nodes can also be added in network selection policies network selection mode is controlled.The node wherein controlling automatic network selection is AutoSelEnabled, if its value is True, then allows ME to carry out automatic network selection; If False, then ME is not allowed to carry out automatic network selection.The node controlling manually to select is ManualSelEnabled, if its value is True, then allows user to carry out manual network selection, if False, does not then allow user to carry out manual network selection.
