Background technique

Third generation cooperative partner program (3rd Generation Partnership Project, abbreviation 3GPP) tissue is fixed Justice network selection policies of the mobile terminal in Idle state, namely selection public land mobile network (Public Land Mobile Network, abbreviation PLMN) strategy, which covers roaming and non-roaming scene.

Under roaming scence, user equipment (User Equipment, abbreviation UE) needs to select visited Public Land mobile Network (Visited PLMN, abbreviation VPLMN), generallys use automatic network selection mode: UE safeguards multiple PLMN lists, each Each PLMN in PLMN list is according to priority ranking；When needing to carry out network selection, UE according to multiple PLMN lists elder generation The available network of sequential selection afterwards when selecting network in a PLMN list, selects highest priority in the list and can be used Network.For roaming scence, sequencing that multiple PLMN lists are selected in each PLMN list each PLMN it is preferential Grade is suitable for all visited places, i.e., same terminal roaming to different countries is grading using identical Network Priority The selection of row network.Detailed process is as follows for a kind of typical network selection in roaming by UE:

(1) UE is switched in visited place or returns to signal coverage from blind area, and UE selects PLMN registration；

(2) the UE preferably before PLMN (Registered PLMN, abbreviation RPLMN) or its equivalence PLMN of successful registration, if RPLMN and its equivalence PLMN are unavailable, then UE is according to each in the successive selecting sequence and each PLMN list of multiple PLMN lists The available PLMN of highest priority in the PLMN list that the priority selection of PLMN preferentially selects, it is assumed that be PLMN A, PLMN A For highest priority and available network in the PLMN list that preferentially selects；

(3) UE executes different system changeover in PLMN A, such as because of execution circuit domain dropping (Circuit Switched Fall Back, abbreviation CSFB) or when having left the signal coverage of current PLMN A, UE selects PLMN B and on PLMN B Successful registration, wherein UE selects the priority of the PLMN list where PLMN B lower than the PLMN list where PLMN A, if PLMN B and PLMN A is in same PLMN list, then the priority of PLMN B is lower than PLMN A；

(4) assume that the PLMN of equal value of PLMN B is PLMN C, and PLMN C and PLMN A have the overlapped signal area of coverage, then when When UE leaves PLMN B and enters the overlapped signal area of coverage of PLMN C and PLMN A, according to current network selection strategy, UE meeting PLMN C is selected, without selecting in the PLMN list that preferentially selects and the higher PLMN A of priority.

When UE is in VPLMN network, UE can execute background scans to select Home Public Land Mobile Network network (Home PLMN, abbreviation HPLMN), or the public land mobile network of equal value with it (Equivalent Home PLMN, referred to as ) or the higher other VPLMN of priority EHPLMN.After step (4), UE resides in PLMN C, then UE will do it background and sweep It retouches, but because HPLMN and EHPLMN are unavailable, then UE can be selected in the PLMN list preferentially selected and priority is higher PLMN A, and return to PLMN A.Then, UE may undergo above-mentioned steps (3) and (4) again, and because background scans turn again to PLMN A.UE will undergo the triangle loopy moving of " PLMN A- > PLMN B- > PLMN C- > PLMN A " in visited place, cause Unnecessary network switching and background scans cause network efficiency of selection low, further, frequent network switching and excessive Background scans, can greatly consume user equipment electricity, cause the user experience of poor roaming place.
