Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art The every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
In embodiments of the present invention, UE can be it is following any one, and UE can be static, can also be movement 's.Static UE may include for terminal (Terminal), mobile station (Mobile Station), subscriber unit (Subscriber Unit) or platform (Station) etc..Mobile UE may include cellular phone (Cellular Phone), Personal digital assistant (Personal Digital Assistant, abbreviation PDA), radio modem (Modem), channel radio Believe equipment, handheld device (handheld), laptop computer (Laptop Computer), wireless phone (Cordless ) or wireless local loop (Wireless Local Loop, abbreviation WLL) platform etc. Phone.Above-mentioned UE can be distributed in entire nothing In gauze network.
In embodiments of the present invention, mobile management net element can be MME or Serving GPRS Support Node (Serving Any one of GPRS Support Node, abbreviation SGSN), MSC or VLR in the embodiment of the present invention, which are usually closed, is set as same Network element, referred to as MSC/VLR, or referred to as VLR.
For the prior art, now it is analyzed as follows：It is registered in the domains CS of the MSC/VLR to restore UE, 3GPP agreements are current The behavior of MME has been done as given a definition：The co-location update that the UE of the MSC/VLR is sent subsequently is registered to before receiving After request or periodic location update request, MME can ask the UE actively to initiate the register flow path to the domains CS.If but MME determines to execute above-mentioned action, then according to the definition of 3GPP agreements, it is " IMSI International Mobile Subscriber Identity that MME, which can initiate separation type, The separation process of (International Mobile Subscriber Identity, abbreviation IMSI) separation ".Initiate the separation The purpose of flow is, it is desirable to which it is " joint tracking fields that UE initiates updating type at once after receiving separation request message The co-location of (Tracking Area, abbreviation TA)/position field (Location Area, abbreviation LA) update and IMSI attachments " More new technological process, to realize the re-registration to the domains CS.The action shows that MME is in the co-location being currently executing more new technological process Or the separation process that separation type is " IMSI separation " is initiated in periodic location update flow.But it is assisted according to 3GPP View, UE are if receiving the separation type that MME is issued in executing co-location more new technological process or periodic location update flow The separation request message of " IMSI separation " will not initiate co-location that updating type is " joint TA/LA and IMSI attachment " more New technological process, to can not achieve the re-registration in the domains CS.The reason of UE is handled in this way is that the separation type that MME is initiated is " IMSI The separation process of separation " only influences the domains CS, and the co-location being currently executing more new technological process or periodic location update Flow, it is ensured that UE continues to keep registering in the domains CS, therefore in order to save unnecessary Signalling exchange, and UE is issued receiving MME Separation type be " IMSI separation " separation request message after no longer initiate co-location more new technological process.
The treatment mechanism of above-mentioned UE destroys MME and wishes that UE initiates the hope registered to the domains CS after MSC/VLR resets and restarts The problem of hoping, causing mainly has：The domains the CS registration of UE could restore when until subsequently having downlink CS business, this certainly will be increased The time delay of follow-up downlink CS business, because must first restore the registration in the domains UE to CS before executing downlink CS business.This can shadow Ring the user experience of downlink CS business；The registration in the domains delay recovery UE to CS can increase UE initiation uplink CS voices and fall back to Unnecessary Signalling exchange behind the domains 2G/3G network C S, to increase the setup delay of uplink CS voices, this can influence uplink CS The user experience of voice.The main reason for leading to this problem is：(a) MSC/VLR after restarting is because above and below the not no registration of UE Literary information can always refuse the CS business request informations that UE is sent after falling back to the domains 2G/3G network C S and trigger UE to initiate position Set more new technological process；If (b) UE launch positions more new technological process, MSC/VLR after restarting because not no UE contextual information, always It can initiate the more new technological process of home location register (Home Location Register, abbreviation HLR).About MME how The co-location more new technological process being currently executing or periodic location update flow are handled, there is no bright for 3GPP agreements at present Really regulation.MME, which is to continue with, executes current position update flowStill current position update flow is terminatedOr refusal is worked as Preceding position update flowFrom the point of view of UE, after initiating co-location more new technological process or periodic location update flow, it can open A dynamic timer waits for MME to send the response message about current location more new technological process.If the timer expiry, UE can retransmission bit More new technological process is set, unnecessary signaling traffic load is generated.
Fig. 1 is the position update processing method flow chart that the embodiment of the present invention one provides, as shown in Figure 1, this method includes：
101, mobile management net element receives the position updating request that user equipment (UE) is sent.
Wherein, which can be co-location update request, or periodic location update is asked. The UE is by initiating combined registering flow (including joint attachment flow or co-location more new technological process) success in moving tube Combined registering is realized on reason network element and MSC/VLR, i.e., realizes the registration in ps domain and the domains CS simultaneously.The UE is meeting centainly When condition, position updating request can be sent to mobile management net element to trigger co-location more new technological process, such as：UE is moved into One new unregistered band of position.
If 102, the MSC/VLR of UE registrations is unreliable, mobile management net element sends instruction information, the instruction information to UE It is used to indicate register flow paths of the UE according to instruction information initiation to the domains CS.
Wherein, instruction information initiates the register flow path to the domains CS for explicit instruction user equipment (UE).The instruction information Realization method can there are many kinds of, including but not limited to：New cell can be used；The content that existing cell can also be changed is come Indicate the instruction information；The instruction information can also be increased in the content for having cell, for example increase a new reason value.
