Description
Technical field
The present invention relates to the communications field, relate more specifically to a kind of method for relocating user equipment.
Background technology
Personal network's (Personal Network is called for short PN) comprises a plurality of access service Public Land Mobile Nerwork individual network elements of (Public Land Mobile Network is called for short PLMN) that are used for by user's control.Having at least one by one in the personal network, people's network element has SIM/USIM (Universal Subscriber Identity Module, universal subscriber identity module) CAMEL-Subscription-Information, the authentication of user capture PLMN just are based on the SIM/USIM information among the personal network.The relative position between the network element is not considered in the management of individual's network element, but carries out with a kind of continuous and reliable connected mode of user's perception.The individual network element that belongs to the individual subscriber network may be registered in different PLMN at synchronization.The facility control personal network of user by using personal network management (Personal Network Management is called for short PNM) to provide.
Personal network's function comprises provides subscriber equipment (User Equipment is called for short UE) redirection business.The UE redirection business refers to that the user can be provided with default UE according to type of service or the professional parameters of using such as medium, when condition that UE in the PN satisfies this setting as the called end of calling out and calling, calls out and is redirected to corresponding default UE.(the somewhat similar traditional Call Forwarding services of UE redirection business).The user can be provided with the different default UE of a series of priority, if be rerouted to the default UE failure of high priority, then selects the default UE of time high priority.
Global system for mobile communications (Global System for Mobile communications, abbreviation GSM), universal mobile telecommunications system (Universal MobileTelecommunications System, be called for short UMTS) wait mobile cellular network employing circuit-switched technology, be called circuit domain (Circuit Switched again, be called for short CS), can be for the user provide basic speech business, and based on the supplementary service of speech business.The PNM business in CS territory is to go up at service control function (GSM Service Control Function is called for short gsmSCF) to realize.
Fig. 1 is the framework schematic diagram of the present invention's entity of being correlated with, comprising following functional entity:
Mobile switching centre's (Mobile Switching Center is called for short MSC)/VLR Visitor Location Register (Visitor Location Register is called for short VLR) 104.
Home subscriber server (Home Subscriber Server is called for short HSS) 106 comprises attaching position register (Home Location Register is called for short HLR) function, preserves user's master data and business datum.
The personal network 110, comprise a plurality of UE by user's control.The personal network is a notion in logic.
Default subscribers equipment 1 (default UE1) 112 when the UE in the PN does called and this calling and satisfies the redirected condition that the user sets, is called out and just is redirected to default UE.
Default subscribers equipment 2 (default UE2) 114 is lower than the priority of default UE1.
UE in the subscriber equipment 116, PN.
In the UE redirection business, the outer UE of PN calls out UE in the PN, calling is at gateway MSC (Gateway MSC, abbreviation GMSC) the PNM business of triggering UE, gsmSCF control GMSC will call out the default UE1 that at first is redirected to high priority, if be redirected to default UE1 failure, gsmSCF control GMSC is redirected to calling the default UE2 of time priority again.In the whole calling procedure, for avoiding calling out the confusion of control, only trigger the PNM business of UE, and should not trigger the PNM business of default UE such as UE1 and UE2 again.
How to be implemented in the PNM business that does not trigger default UE when UE is redirected, also not have ready-made method at present.
Summary of the invention
One or more problems in view of the above the present invention proposes a kind of method for relocating user equipment.The professional repeated trigger of PNM can be implemented in the ability that does not trigger the PNM business of default UE when UE is redirected in the time of can avoiding CS territory PNM UE to be redirected.
PNM IN service for the default UE that realizes not triggering redirection business, gsmSCF is when triggering redirection business, the number of former called UE in the PN is issued GMSC as original called party number with CONNECT message, this original called party number is passed to the GMSC1 that is responsible for obtaining default UE routing iinformation by GMSC, GMSC1 is again by passing to gsmSCF in initial trigger point (Initial DP) message, gscSCF judges, and called (being default UE) is former called redirected default UE, thereby do not trigger the PNM business of default UE.
Implementation method provided by the invention may further comprise the steps:
S202, UE in the PN (with reference to figure 1 108) do calledly, GMSC triggers the IN service of this UE.In the UE redirection business is handled, carry the relevant information of former called (being UE in the PN) in the CONNECT message that gsmSCF sends out to GMSC, this former called party information is passed to the GMSC1 of the routing iinformation of being responsible for obtaining default UE by GMSC.
S204, GMSC1 obtain the routing iinformation of default UE, and (Terminating CAMEL Subscription Information exhales the IN service CAMEL-Subscription-Information eventually according to the T-CSI of default UE.CAMEL, Customised Application for Mobile network EnhancedLogic, surely the mobile network that can make strengthens logic and uses) trigger intelligent business is to gsmSCF, carries the number of called (default UE) and the former called relevant information among the step S202 in Initial DP (initial trigger point) message.
S206, gsmSCF are according to called and former called relevant information, and judging called is former called redirected default UE, does not carry out the PNM operation flow of default UE, sends out CONTINUE to GMSC1.
Wherein, in S202, former called party information can be the number of former called (UE in the PN), also can be special redirection information (redirection information), also can be special universal number (Generic Number), or the like.
Wherein, in S202, if former called party information is the number of former called (UE in the PN), this number can carry by original called party number (Original Called Party ID) field, also can carry by redirect number (Redirecting Party ID) field.
Wherein, in S204, GMSC1 and GMSC can be same network entities, also can be different network entities.
Wherein, in S206, if the T-CSI of default UE only corresponding the PNM business, after gsmSCF sends out CONTINUE message to GMSC1 so, finish monitoring to this calling; If T-CSI has also bundled other IN service, then gsmSCF only ignores the logic of PNM business, decides with the message interaction process of GMSC1 other intelligent service logic by the T-CSI binding.
Because the present invention is in the processing that UE is redirected, adopted when triggering the IN service of default UE and given gsmSCF the information band of former called (UE in the PN), gsmSCF can judge this calling in view of the above, and thereby the redirected PNM IN service flow process of not carrying out default UE of UE has taken place, therefore reached the purpose that does not trigger the PNM business of default UE when UE is redirected, reach the effect of existing network element not being had influence simultaneously, improved the PNM availability of traffics.
