C, UE send corresponding update inquiry information to network side.
D, network side are according to the corresponding positional information of safeguarding this UE of described update inquiry information.
Below specifically describe the inventive method by two examples.
Method example one: EnodeB id initiates the position immediately and upgrades not simultaneously.Referring to shown in Figure 6, comprise the following steps:
Under S101, the idle condition or be in UE reading system broadcast under the energy-saving mode of state of activation.
EnodeB is when constructing system broadcast information, and EnodeB adds the id information of this EnodeB by its built-in adding device in this system broadcast message.
After EnodeB finishes interpolation EnodeB id operation, system broadcast message is issued on the broadcast channel, UE reads the system broadcast information on the broadcast channel.
S102, UE judge whether EnodeB id is identical, if inequality, then change step S103 over to; Otherwise, do not deal with.
Whether the EnodeB id in the system broadcast message that described UE reads by the first comparing unit comparison receiving element is identical with EnodeB id in the positional information of cell stores, if it is identical, the zone of not striding the EnodeB covering of moving of this UE then is described, upgrade so need not to carry out the position in order to economize on electricity, promptly UE does not deal with; As if inequality, the mobile zone of having crossed over the EnodeB covering of this UE then is described, change step S103 over to.
S103, UE send the EnodeB update inquiry information to network side.
EnodeB id is not simultaneously in this example, then initiating the position immediately upgrades, so UE compares EnodeB id when inequality at first comparing unit, carry the EnodeB update inquiry information of the EnodeB id that stores among the UE by the update request unit structure, and send to network side.
S104, network side are according to the corresponding positional information of safeguarding this UE of EnodeB update inquiry information.

So far, finished the updating location information flow process, the UE positional information in the context that this moment, network side was preserved is not only the current actual position information of UE, and has been accurate to the EnodeB at UE place; Store the id of the EnodeB at its current place this moment among the UE, in the process of continuous reading system broadcast, wait for and judge next time and trigger more new technological process once more when EnodeB id is inequality.
Referring to shown in Figure 7, when described UE was paged, network side can be according to the EnodeB id in the positional information of this UE, and radio paging information gets final product in the sub-district that this EnodeB covers.If abnormal conditions occur, cause paging failure, then can in the TA at the current place of UE scope, carry out paging.
This example for the position is upgraded, can repeat to send out an EnodeB update inquiry information, but the coverage of TA is very big, can often not upgrade, so this example still can be implemented when EnodeB id and TA id all change.
Method example two: EnodeB id difference, judge further whether TA id is identical, initiate the position again and upgrade.Referring to shown in Figure 8, comprise following concrete steps:
Under S201, the idle condition or be in UE reading system broadcast under the energy-saving mode of state of activation.
In the prior art, comprised TA id in the system broadcast message.
This step other guide is identical with step S101.
S202, UE judge whether EnodeB id is identical, if inequality, then change step S203 over to; Otherwise, do not deal with.(S102 is identical with step)
S203, UE judge whether TA id is identical, if identical, then change step S204 over to; Otherwise, change step S206 over to.
Whether the TA id in the system broadcast message that described UE reads by the second comparing unit comparison receiving element is identical with TA id in the positional information of cell stores, if it is identical, the mobile service area of not striding of this UE then is described, get final product so only need initiate the renewal of EnodeB position, promptly change step S204 over to; If inequality, the mobile service area of having crossed over of this UE then is described, upgrade so need carry out the TA position, also to carry out the EnodeB position simultaneously and upgrade, promptly change step S206 over to.
S204, UE send the EnodeB update inquiry information to network side.
UE carries the EnodeB update inquiry information of the EnodeB id that stores among the UE by the update request unit structure, and sends to network side.
S205, network side are according to the corresponding positional information of safeguarding this UE of EnodeB update inquiry information.(S104 is identical with step)
So far, finished the updating location information flow process.Referring to shown in Figure 7, when described UE was paged, network side can be according to the EnodeB id in the positional information of this UE, and radio paging information gets final product in the sub-district that this EnodeB covers.If abnormal conditions occur, cause paging failure, then can in the TA at the current place of UE scope, carry out paging.
S206, UE send EnodeB or TA update inquiry information to network side.
UE carries the EnodeB id that stores among the UE and the EnodeB update inquiry information of TA id by the update request unit structure, and sends to network side.
Perhaps, UE carries the EnodeB id that stores among the UE and the TA update inquiry information of TA id by the update request unit structure, and sends to network side.
S207, network side are according to EnodeB or the corresponding positional information of safeguarding this UE of TA update inquiry information.
Gateway GW, the EnodeB of network side, perhaps other network elements with maintenance position informational function are according to EnodeB id in described EnodeB or the TA update inquiry information and TA id, and the positional information to UE in the context that network side is preserved is upgraded.
If network side is by the parsing to update inquiry information, variation has taken place in the TA that detects the UE place, then initiates the re-registration process of TA.
Afterwards, the network side structure upgrades acknowledge message and is issued to UE, carries the id information (new EnodeB id) of UE present located EnodeB in this renewal acknowledge message.
If carried out the TA re-registration process in the aforementioned process, upgrade in the acknowledge message id information except the EnodeB that carries the current place of UE, also to carry the TA id information at the current place of UE.(new TA id information)
UE receives described renewal acknowledge message by receiving element, and to upgrade the EnodeB id (with TA id) that the EnodeB id (with TA id) that carries in the acknowledge message upgrades former storage.
So far, finished the updating location information flow process.Referring to shown in Figure 7, when described UE was paged, network side can be according to the EnodeB id in the positional information of this UE, and radio paging information gets final product in the sub-district that this EnodeB covers.If abnormal conditions occur, cause paging failure, then can in the TA at the current place of UE scope, carry out paging.
