Fig. 1 is the schematic diagram of the network selection flow process of subscriber equipment under CL pattern.For the start network selection flow process of UE10, the network selection flow process at present under CL pattern is roughly as follows:
Under 101, CL pattern, UE10 starts shooting.
102, UE10 reads multimode network selection allocation list information.
Wherein, multimode network selection allocation list information can comprise multimode system preference lists (MMSSSystemPriorityList, be called for short " MSPL ") preference lists (MMSSLocationAssociatedPriorityList is called for short " the MLPL ") fileinfo that is associated of fileinfo and position.
103, check memory network selection information or use initial ranging to determine MSPL table position.
104, check that MSPL shows, determine the priority of LTE network and HRPD network, the network that UE10 override requests access priority is high.
If the priority of LTE network is higher than HRPD network, then perform 105 to 108.
105, UE10 preferentially attempts network selection registration under LTE network.
106, judge whether successfully network selection or registration under LTE network.
107, when LTE network selection or registration failure, UE10 closes LTE network.
108, UE10 continues under HRPD network, attempt network selection registration.
On the contrary, if the priority of HRPD network is higher than LTE network, then perform 109 to 112.
109, UE10 preferentially attempts network selection registration under HRPD network
110, judge whether successfully network selection or registration under HRPD network.
111, when HRPD network selection or registration failure, UE10 closes HRPD network.
112, UE10 continues under LTE network, attempt network selection registration.
Can see, be configured to the terminal of CL pattern, under HRPD network after network selection failure, can continue to select LTE network; Conversely, can continue to select HRPD network after network selection failure under LTE network.Should be understood that this network selection flow process that Fig. 1 describes can comprise and real search the register flow path after net flow process and resident success.
In the present embodiment, assuming that UE10 is current be in LTE network under, TAU flow process for realizing the location updating of UE10, when the position of UE10 changes, can by up-to-date location information notification to core net; ATTACH flow process is for realizing the position registration of UE10, and namely to the information of registers kernel network UE10, after only succeeding in registration, UE10 just can initiating business request, initiates paging and response paging; After succeeding in registration, when UE10 needs initiation business, first to set up corresponding connection by initiating business request, and recover relevant bearer.UE10 can be comprised #3 (IllegalME), #6 (IllegalUE), #7 (EPSservicesnotallowed) or #8 (EPSservicesandnon-EPSservicesnotallowed) when carrying out above-mentioned TAU flow process, ATTACH flow process, DETACH flow process or service request flow process by the cause value that network side is refused.When UE10 is rejected because of error reason #3, #6 or #8, UE10 needs to think PS card and circuit commutative field (CircuitSwitchingDomain under LTE standard, being called for short " CS ") card is all invalid, follow-uply possibly cannot provide PS business under LTE network and CS business.When UE10 is rejected because of error reason #7, UE10 needs to think that PS card is invalid, and follow-up possibly cannot provide PS business.Wherein, PS card and CS cartoon often can be integrated in same SIM card, can think the difference in functionality of SIM card, are used for realizing the registration of user profile to core net, to realize PS business under LTE network and CS business respectively.Therefore, in the present embodiment by the PS card correlation function of LTE (as to LTE network log-on data business and perform data function) referred to as PS card, by CS card correlation function (as to LTE network registration speech business and execution phonetic function) referred to as CS card.The data service function that PS card or PS card function namely perform under LTE standard.
After PS business under LTE network is unavailable, for the UE10 supporting CL access module at present, it is resident that UE10 can select other patterns to carry out.Under current CL pattern, 1x and HRPD or 1x and LTE pattern (or be standard, or wireless access technology (RadioInterfaceTechnologies, be called for short " RAT ")) all can be resident, therefore under current scene, UE10 proceeds data service after HRPD (high rate packet data) (EnhancedHighRatePacketData, be called for short " the EHRPD ") network of HRPD network or evolution can be selected again resident.If this HRPD network follow-up becomes unavailable, or UE10 in data service procedures again occurrence positions move, move to without the HRPD network coverage but the community having LTE network to cover, UE10 needs to rejoin LTE network.Or UE10 can select based on user or triggering rejoins LTE network or the resident Preset Time (being realized by the timing of setting timer) that exceedes is attempted rejoining LTE network afterwards under HRPD network.
Based on said system application scenarios, the changing method that the embodiment of the present invention proposes, access HRPD network after subscriber equipment is caused PS card invalid by LTE network refusal, and HRPD network subsequent is unavailable or this subscriber equipment moves to without the HRPD network coverage but the region having LTE network to cover time, can be effective by the PS card reset for LTE network, make subscriber equipment again to carry out registering and providing data service under LTE network.
The SIM card of especially opening an account for subscriber equipment is contracted the situation of Duo Jia operator, after by the LTE network refusal under an operator, by arranging PS card effectively, follow-uply can attempt the LTE network connecting an other operator.Certainly, the present embodiment do not get rid of yet subscriber equipment again attempt resident same operator under LTE network.When subscriber equipment is attempted initiating request to the LTE network under same operator again, once be refused with same cause by this LTE network, still other LTE network can be attempted.
Fig. 2 is the flow process interaction figure of the changing method of one embodiment of the invention.UE10, CN20 and CN30 have been shown in Fig. 2, wherein, in the description to the flow process shown in Fig. 2, LTE network refers to the corresponding core net of LTE standard, UE10 is by communicating between corresponding base station with this LTE network, namely between CN20 and UE10, and communicated by corresponding base station between CN30 and UE10.As shown in Figure 2, this switching flow specifically comprises:
201, UE10 is configured to support HRPD network and LTE network simultaneously, and wherein, the current resident LTE network of UE10 is core net CN20.
202, UE10 sends a request message to CN20.
Wherein, this request message can comprise login request message, go login request message or business request information, and login request message can comprise ATTACH request message and TAU request message, removes login request message and DETACH request message.The register flow path that UE10 carries out in moving process, can comprise unit registration or combined registering, thus initiate registration request to network.
Wherein, this request message is that UE10 is sent to CN20 by base station, and namely UE10 sends this request message to corresponding base station, and forwards this request message by this base station to CN20.
203, CN20 sends refuse information to UE10.
Wherein, this refuse information can comprise: ATTACH refuse information, TAU refuse information, DETACH refuse information or service denial message.This refuse information can carry error reason value #3, #6, #7 or #8.
Wherein, CN20 sends this refuse information by base station to UE10, and namely CN20 sends this refuse information to corresponding base station, and forwards this refuse information by this base station to UE10.
It is invalid that 204, UE10 arranges PS card.
After UE10 initiation request under LTE network is rejected and causes PS card invalid, follow-uply no longer select LTE network.
205, UE10 accesses HRPD network.
UE10 selects other access modules, attempts search HRPD network, provides service after resident success under HRPD network.
It is effective that 206, UE10 arranges PS card.
After UE10 accesses this HRPD network, when communicating under this HRPD network, this PS card function is re-set as effectively.
Request of initiating under the LTE network that agreement specifies is refused to cause PS card invalid until next switching on and shutting down are just again effective, just for 3GPP agreement, and at present for the above-mentioned application scenarios mentioned, UE10 has switched to the standard of 3GPP2 from 3GPP standard, now, PS card can be re-set as effectively by we, think that PS territory can be used, be similar to UE10 and carry out shutdown process, like this, after UE10 selects HRPD network, if follow-up UE10 cannot continue to connect HRPD network, such as this HRPD network becomes unavailable, or UE10 moves to other regions without the HRPD network coverage, or during due to a variety of causes loss network, UE10 can also by continuing to select the network of LTE to carry out resident rear initiation registration, and PS business is provided, improve Consumer's Experience.
207, when UE10 cannot continue to connect HRPD network, UE10 attempts search LTE network, searches for successfully resident.
Particularly, when UE10 moves to the region without the HRPD network coverage, when cannot continue to connect described HRPD network; Or follow-up HRPD network becomes unavailable, when cannot continue to continue to provide service under this HRPD; Or when the residence time of UE10 under HRPD network exceedes Preset Time; Or when UE10 receives and uses the selection of the user of this UE10 and be triggered, UE10 can select other access modules, attempt the LTE network that search is new, such as UE10 can attempt the access 4G network of different operators or other heterogeneous networks of same operator, search under residing in this LTE network successfully, that is, the PLMN network number of the former LTE network that the public land mobile network of this LTE network (PublicLandMobileNetwork is called for short " PLMN ") network number is resident with UE10 in 201 to 202 is not identical.
Wherein, user by selecting and trigger UE10 and carry out network connection can be that user is performed by the user interface (UserInterface is called for short " UI ") of UE10.
Can understand, when UE10 move to without the HRPD network coverage but the region having LTE network to cover time, if this region only has a LTE network, UE10 can select to access this LTE network, if there is multiple different LTE network in this region, UE10 can select one of them LTE network to access, such as UE10 can according to user's control PLMN (UserControlledPLMN in SIM card, be called for short " UPLMN ") and operator control PLMN (OperatorControlledPLMN, be called for short " OPLMN ") priority select LTE network, the LTE network that preferential trial access priority is high, when this LTE network access failure, can sequentially attempt other LTE network of access according to the priority successively again.
208, UE10 sends ATTACH request message to CN30.
UE10 selects to access new LTE network, i.e. CN30 in 207, again initiates ATTACH flow process, to the information of CN30 request registration UE10.
Wherein, this ATTACH request message is that UE10 is sent to CN30 by base station, and namely UE10 sends this ATTACH request message to corresponding base station, and forwards this ATTACH request message by this base station to CN30.
209, CN30 sends ATTACH success response message to UE10.
Wherein, CN30 sends this ATTACH success message by base station to UE10, and namely CN30 sends this ATTACH success message to corresponding base station, and forwards this ATTACH success message by this base station to UE10.
210, UE10 continues to provide service under LTE network.
UE10, after the process of above-mentioned setting and selection, can again register and carry out data service under LTE network.
Therefore, the changing method of the embodiment of the present invention, subscriber equipment is caused the invalid rear access HRPD network of PS card by LTE network refusal, when HRPD network subsequent is unavailable, or the residence time of UE under this HRPD network exceedes Preset Time, or when UE is subject to the selection of its use user and is triggered, effective by arranging PS card, make subscriber equipment again to carry out registering and providing data service under LTE network.
The situation of the SIM card of especially subscriber equipment being opened an account signing Duo Jia operator simultaneously, when Duo Jia operator is deployed with 4G network simultaneously, if wherein an operator not yet opens 4G business, access the 4G network of this operator of family be rejected cause PS card invalid time, after the follow-up HRPD of being linked into network provides one section to serve, enter into the region only having LTE network to cover without the HRPD network coverage, subscriber equipment is effective by arranging PS card, just again can select the 4G network attempting other operators of access, and continue to provide service, improve Consumer's Experience.
Can understand, the changing method described in the embodiment of the present invention, go for the situation that subscriber equipment comprises single baseband chip, the situation that subscriber equipment comprises many baseband chips can also be applicable to, be i.e. the situation of patch mode.
