The wireless dummy roaming system that the present invention of being shown in Figure 3 proposes, wireless dummy roaming system of the present invention is as follows with the main distinction of the about cellular wireless system of tradition:

1) the wireless dummy roaming system is by wireless exchange board MSC/VLR, HLR, AUC forms, do not have base station controller BTS and base station BS part, be connected with the wireless exchange board of two or more cellular carriers simultaneously, certain customers' data of the cellular carrier that in HLR, connects to some extent.

2) the HLR function of the HLR of wireless dummy roaming system and standard has expansion, and the user with wireless dummy roaming function should register at two or more HLR that belong to the different radio transportation simultaneously, and the information of registration can be mapped.

For example, operator's first and certain cellular carrier second are signatory, certain customers' data of managed operation merchant second, and these user data are placed among the HLR of Virtual Wandering System of operator's first. Simultaneously, among the HLR of the Virtual Wandering System that operator's first also is also placed in certain customers' data of its management, the user data of operator's first is arranged simultaneously among the HLR of the Virtual Wandering System of operator's first like this, the user data of operator's second is also arranged; The user data that the 3rd operator also can be arranged certainly.

And the user of Virtual Wandering System has two or more identity, and the user that he is operator's first also is the user of operator's second, and but, this user's data all exist among the HLR of Virtual Wandering System. And managed by Virtual Wandering System. At this moment it is as follows to store this user's data content at Virtual Wandering System:

IMSI1	MSISDN1	HLRn1
			IMSI2	MSISDN2	HLRn2
IMSI3	MSISDN3	HLRn3
			Deng	Deng	Deng

The networking enrollment process

Suppose that this virtual roaming user belongs to two wireless networks simultaneously, at this moment enter network process and formed by two processes:

Suppose that present user is just in first operator's wireless network

The wireless enrollment process of the enrollment process standard of first operator	The enrollment process of the enrollment process virtual radio system of second operator
		1) when the mobile subscriber requires access network, it sends access request at wave point;	Attonity
2) MSC/VLR is passed in request access, and MSC/VLR is then according to this mobile subscriber's MSI number	Attonity

Ask its HLR that corresponding parameter group is provided, MSC/VLR selects one of them parameter group, and its random parameter RAND is sent to travelling carriage;
		3) when mobile user contracted, relevant user's data such as IMSf, Ki not only is input among the HLR/AUC, also to write in user's the SIM, receive RAND after, the SrM card is according to A3 and A8 algorithm, calculate symbol response SRES and the encryption key Kc of authentication, SRES is returned to MSC/VLR; (this part of CDMA is slightly different)	Attonity
4) after MSC/VLR receives SRES, it is compared with the SRES that sends here among the HLR/AUC, if identical, then network, not identical, refusal just;	Attonity
		5) in HLR, record the MSC number at the HLR place at this present place of mobile subscriber;	The MSC number that contains the HLR place of this user data
6) in VLR, record the residential quarter at this present place of mobile subscriber, and certain customers' data are copied from HLR.	Contain and record this user on the VLR of MSC at HLR place of this user data at present just on certain residential quarter XXXXXXX, but this residential quarter reality does not exist, and is virtual, and certain customers' data are copied from HLR.

Suppose that the identity with IMSI1 networks in this user certain residential quarter LAC (being referred to as LAC actual) in certain MSC of operator 1 (being referred to as MSC-actual), at this moment the information of this user under the radio roaming system log (SYSLOG) is as follows:
