Embodiment
First embodiment
When present embodiment is the employing MSCe of system disaster-tolerant backup mode, realize the called method of portable terminal when MSCe is unusual.
The MSCe disaster-tolerant backup is promptly to BSC (Base Station Controller, base station controller), HLR (Home Location Register, attaching position register), MGW (Media Gateway, media gateway), PSTN (Public Switched Telephone Network, public switch telephone network), SMC (Short Message Center, short message service center) network element such as has the MSCe of a redundancy.The network picture group as shown in Figure 1.
Under the situation of MSCe disaster-tolerant backup, synchronization, it is in running order only to have the main MSCe of using, and another MSCe is in stand-by state.When the master used the MSCe fault, standby MSCe came into operation.In this case, can solve original master by following method and can't do called problem with the portable terminal under the MSCe before doing caller or autonomous registration, processing procedure is as follows:
Step 110, standby MSCe regularly detects main running status with MSCe;
Detect the master and can be undertaken by standby MSCe, also can be undertaken, perhaps adopt both combinations by third party's module with the running status of MSCe.
Whether step 120 is judged main normally with MSCe work, if mainly occurred unusually with MSCe, standby MSCe then sends message to HLR, makes the standby MSCe of pointed of HLR, is about to all and is registered in former master and changes into the portable terminal of MSCe and being registered on the standby MSCe;
In other embodiments, also can send message to HLR by third party's module.Message comprises the information of fault MSCe and standby MSCe.
Step 130, HLR all is revised as the pointer of all sensing fault MSCe in the portable terminal on it and points to standby MSCe.
Like this, when former master makes when called of the portable terminal under the MSCe, former standby MSCe (having become the main MSCe of using now) can send out a beep-page message.
Second embodiment
When present embodiment is the employing MSCe of system load sharing mode, realize the called method of portable terminal when MSCe is unusual.
The MSCe load sharing promptly as shown in Figure 2, a BSC can insert the MSCe " pond " that a plurality of MSCe network elements are formed, when BSC handles from the call message of portable terminal or registration message, select certain MSCe among the MSCe " pond " to handle business application according to the load sharing algorithm, thereby realize the load balancing of MSCe from portable terminal.
Called for portable terminal, after certain MSCe sent the paging request to BSC, BSC can send to the MSCe that sends the paging request to the page-response message of portable terminal.
After certain MSCe fault among the MSCe " pond ", before portable terminal is independently registered or done caller, realize that this part portable terminal does called method and may further comprise the steps:
Step 210, portable terminal is done when called, if outbound call, HLR is before sending RouteRequest message (route request information) MSCe affiliated to called mobile terminal, and whether the office direction that determines this MSCe earlier can reach, if can reach, then continue normal flow, if unreachable, then think this MSCe fault, execution in step 220;
If HLR judge should be called be Home Exchange Call, then directly get final product by this MSCe transmission beep-page message, do not exist portable terminal can't do called problem.
Step 220, HLR adopts certain algorithm to select any MSCe of normal operation among the MSCe " pond ", with originally sending to the message of fault MSCe, sends to the MSCe that reselects;
It can be to select one arbitrarily that HLR selects the algorithm of MSCe, also can select a MSCe by the load sharing algorithm.
Step 230, this MSCe sends the whole network beep-page message, and promptly this MSCe all BSC under it send the whole network beep-page message;
The shortcoming of this method be all portable terminals below fault MSCe independently register or do caller before MSCe available in the MSCe " pond " may occur and can't accomplish load balancing completely, but after this part portable terminal is independently registered or done caller, will realize the MSCe load balancing in the MSCe " pond " again.
The 3rd embodiment
When present embodiment is the employing MSCe of system load sharing mode, realize the called other method of portable terminal when MSCe is unusual.
Step 410, BSC regularly detects MSCe;
Step 420, as if certain the MSCe fault that detects among the MSCe " pond ", this BSC then notifies its BTS (Base Transceiver System down, base station transceiver), revise the cell parameter of configuration, allow portable terminal independently register at short notice, after the mobile phone registration, change back right value again;
BSC judges that the MSCe fault can detect by signaling link, if link is obstructed, then thinks the MSCe fault.
The cell parameter that can revise has a lot, have on the air protocol, for example: SCI (SLOT_CYCLE_INDEXp, slot cycle), SCMp (Station Class Mark, travelling carriage rank sign), call termination activates indicating device (The call termination enabled indicators) as MOB_TERM_HOMEp, MOB_TERM_FOR_SIDp and MOB_TERM_FOR_NIDp, can revise some other performance index in addition, as The operatingmodes (operational mode), Transmit diversity (transmit diversity mode) is as OTD (Orthogonal Transmit Diversity) or STS (spreading diversity during sky) etc., also can shorten cycle register, allow the very fast registration of mobile phone, and then change back.In a word, after this cell parameter is revised portable terminal is independently registered gets final product.
Step 430, all mobile terminal enquiries are revised to cell parameter in this MSCe " pond ", independently register.
Portable terminal is regularly received empty overhead message, carries the parameter of base station in this message, and portable terminal compares parameter in the Overhead Message and the parameter of oneself preserving, and judges whether cell parameter is revised.
During the portable terminal registration, its MSCe that visits of record is used for called on HLR.
Because being BSC " pond ", the networking of MSCe load sharing is connected to MSCe " pond ", so, if certain MSCe fault, then all BSC in the BSC " pond " can detect, all cell parameters of BTS that BSC revises below it are independently registered by portable terminal, will cause all independently registrations of portable terminals all in this MSCe " pond ", BSC can only control this BSC allows portable terminal register in the sub-district of the BTS of extension down in batches, but can't be from all separately registrations of portable terminal of overall situation control.May cause the portable terminal of registration in the certain hour many especially like this, HLR may be subjected to the restriction of disposal ability.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
