The embodiment of the invention provides the method for calibration and the service server of Temporary Mobile Subscriber Identity, can prevent the cross-talk of user terminal, below is elaborated respectively.
The method of calibration of embodiment one, a kind of Temporary Mobile Subscriber Identity, flow process comprise as shown in Figure 1:
A1, service server receives the service request of carrying Temporary Mobile Subscriber Identity that user terminal sends; The signing messages that comprises described user in the described Temporary Mobile Subscriber Identity;
Among the present invention; described service server can be network entities such as mobile switching centre, Service Switching Point; be understandable that; different network types can have different Business Entity correspondences, and the present invention emphasizes that the network entity with service access and control of authority all belongs to protection scope of the present invention.
Among the mobile network, that Subscriber Identity Module (SIM card) is represented is the user.In a terminal, may place two SIM card, promptly present double card double standby mobile phone, in this case, a user has two SIM card, corresponding terminal.And Temporary Mobile Subscriber Identity and SIM card correspondence.
In the present embodiment, described signing messages can be described user's Subscriber Identity Module (SIM card) coding; It also can be the machine code of described user terminal; Can also be other the existing various signs that can distinguish the user; If adopt the signing messages of the existing sign conduct of this class, network side can carry out network registry the user, adheres to, the position is upgraded waiting time and realized the obtaining of above-mentioned existing sign, and sets up the index information in the Temporary Mobile Subscriber Identity that distributes and the corresponding relation of signing messages.Concrete obtain manner can adopt multiple usual manner to realize, is not construed as limiting the invention.
Be appreciated that described signing messages also can be after network side generates in advance, be handed down to user terminal by the Temporary Mobile Subscriber Identity that distributes.The present invention emphasizes that signing messages can this user of unique identification, be used for verification to Temporary Mobile Subscriber Identity, the signing messages that generates is except being handed down to the user by Temporary Mobile Subscriber Identity, can also send separately, the concrete form of expression that generates signing messages can be multiple, can be numeral, for example: 1,2,3,4......; Also can be ASCII character, for example: forms such as A, B, C, D.......
The present invention is the corresponding relation between index information and user's the signing messages in the network side preservation Temporary Mobile Subscriber Identity in advance, so that whether network side can correct by the Temporary Mobile Subscriber Identity that the signing messages verified users sends.
For the form of Temporary Mobile Subscriber Identity, describe for example below, below only be that of Temporary Mobile gives an example, the particular content that Temporary Mobile comprises can also increase and decrease according to the difference of network, and concrete structure is not construed as limiting the invention.
Temporary Mobile Subscriber Identity is the integer of a 32bit in this example, and form is as follows:
TMSI=CS/PS sign+VLR reboot flag+NRI+Index
Wherein, the CS/PS sign accounts for 2bit, represents that this TMSI is that circuit switching (CS) territory is used or packet switching (PS) territory is used.
VLR Visitor Location Register (VLR) reboot flag accounts for 1～3bit, is controlled voluntarily by producer.
NRI is a network resource identifier, accounts for 0～10bit, sign mobile switching centre when being used for mobile switching centre pond (MSC Pool) networking.
Remaining bit draws and is used for index information, identifies each user terminal.
For instance, the VLR reboot flag is generally used 1bit, and the NRI sign is generally used 6bit, and like this, also remaining 32-2-1-6=23bit can be used for Index, can represent the address space of 2^23=800 general-purpose family terminal.
