Technical field
The present invention relates to the mobile communication technology field, be meant a kind of method that the mobile communication terminal position updating of status of fail is upgraded in the position that is in especially.
Background technology
When mobile communication terminal moves on to another sub-district from a sub-district, the Broadcast Control Channel of the former sub-district that terminal receives (Broadcast Control Channel, BCCH) CF signal intensity more and more a little less than, and the BCCH CF signal intensity of another sub-district is more and more stronger.When near certain terminal moves to theoretical boundary, two sub-districts was a bit, terminal will find that the BCCH CF signal intensity of another sub-district is better than former sub-district, so decision is transferred on the wireless frequency of new sub-district.This new carrier frequency of terminal locking continues to receive broadcast and may issue its beep-page message, continues to move to other sub-district up to it.(Location Area Identity, LAI), terminal is not carried out the position and is upgraded if there is identical Location Area Identification two sub-districts.If the LAI difference of two sub-districts, terminal is learned new Location Area Identification and Subscriber Identity Module (Subscriber Identity Module from the broadcast of BCCH, SIM) it is inconsistent that the Location Area Identification of record compares discovery in, then terminal will be sent location update request message to network side position updating block, and the informing network side is upgraded the LAI of this portable terminal that is write down.
After network side position updating block is received location update request message, upgrade in the network about this location information of terminals, send the position to terminal and upgrade success message, terminal is received position renewal success message, then the position is upgraded successfully, and it is consistent with the location registers situation of terminal in network that situation is upgraded in the position that terminal write down.Otherwise failure is upgraded in the position, and position renewal situation and the location registers situation of terminal in network that terminal write down are still inconsistent.
Position update mode information in the Subscriber Identity Module of mobile communication terminal has write down the position of terminal in network side and has upgraded the result, and according to the definition among GSM04.08 and the 3GPP TS24.008, the position is upgraded three kinds of states:
(1) U1 UPDATED: the position is upgraded successfully, deposits the information such as Location Area Identification of user's registration among the SIM;
(2) U2 NOT UPDATED: the position updating process failure does not have information such as effective LAI among the SIM;
(3) U3 ROAMING NOT ALLOWED: position updating process is successful, but obtains the negative response (because roaming or signatory restriction) of network side, and information such as effective LAI can be arranged among the SIM.
It is U2 NOT UPDATED that the position update mode that writes down among the SIM of failure back is upgraded in the position.
There are four class situations in the position updating process failure:
(1) network side does not learn that this position of terminal upgrades failure, and the terminal positional information of depositing in the network side is old positional information, and terminal has been left old lane place and entered new lane place;
(2) network side is learned this position renewal failure of terminal, and network side has been lost location information of terminals;
(3) network side is learned this position renewal failure of terminal, but network side has write down the new positional information of terminal;
(4) network side does not learn that this position of terminal upgrades failure, but the positional information of depositing in the lane place at terminal place and the network side is consistent.
In the prior art, allow terminal change U1 UPDATED state over to from U2 NOT UPDATED state, GSM04.08 and 3GPP TS24.008 have put down in writing two kinds of methods:
(1) terminal is after periodical position renewing timer is overtime, send periodic location update message to network side, after network side is received periodic location update message, upgrade in the network side about this location information of terminals, send the position renewal to terminal and accept message, terminal is received that the position is upgraded and is accepted message, upgrades the positional information among the SIM, then periodic location update success.
(2) from the system message of sub-district, place, learn position district sign after, terminal is initiated normal position updating process, sends location update message to network, and message is accepted in renewal if terminal is received the position, terminal enters U1 UPDATED state, and then the position is upgraded successfully; Do not upgrade response message if receive the position, then failure is upgraded in the position, and terminal can enter U2 NOT UPDATED state; Upgrade refuse information if receive the position, then enter U3 ROAMING NOT ALLOWED state.
In the prior art, be in the position and upgrade the terminal of status of fail, after the paging of receiving network side, still can only the latent period position renewing timer overtime or initiate the position again when receiving the system message of sub-district and upgrade, therefore may there be the long inconsistent phase, and do not consider and initiate position updating process at this moment, can shorten terminal and be in the time that status of fail is upgraded in the position.
