And utilize present roaming technology, can't realize the requirement that the user roams between heterogeneous network.

Summary of the invention

Defective and deficiency at the prior art existence, the invention provides a kind of roaming method between heterogeneous networks, can make the user between two (or more than) networks, realize roaming, thereby overcoming existing mobile communcations system can't satisfy, the user can keep under the prerequisite of a number, between different networks in the requirement of realization mobile service.

In order to reach the foregoing invention purpose, roaming method between heterogeneous networks of the present invention may further comprise the steps:

(A) Home Location Register storage bimodulus or the multimode terminal user user profile in various available mobile networks;

(B) during terminal user roaming to available mobile network, Home Location Register is updated to the mobile network that roamed with the mobile network who uses before the terminal user roaming according to the type of the location update message of terminal use's initiation in Home Location Register;

(C) mobile network who is roamed according to preserve in the Home Location Register with the corresponding user profile of this terminal use, carry out follow-up mobile service and handle.

Above-mentioned roaming method between heterogeneous networks, wherein, described step (B) specifically may further comprise the steps:

(B1) during terminal user roaming to available mobile network, initiate location update message to Home Location Register;

(B2) Home Location Register judges that according to the type of the location update message that receives described terminal use roams mobile network's type at place at present;

(B3) Home Location Register is set at mobile network's type that the terminal use uses at present with mobile network's type that the terminal use roams the place at present.

Above-mentioned roaming method between heterogeneous networks, wherein, in the described step (B1), bimodulus or the multimode terminal user user profile in various available mobile networks is accepted interface by the user profile of OSS and is saved in the Home Location Register.

Above-mentioned roaming method between heterogeneous networks, wherein, in the described step (B2), the type of location update message is to determine by the network type definition value in the described location update message.

Adopt technical scheme of the present invention, compared with prior art, utilize same Home Location Register to preserve user's heterogeneous networks information, allow the user realize mobile service, allow the user obtain better communication and experience different mobile networks.

Embodiment

The present invention is described in further detail below in conjunction with the drawings and specific embodiments:

" roaming method between heterogeneous networks " provided by the present invention is in order to satisfy the demand that the user utilizes same Mobile Subscriber International ISDN Number to roam between heterogeneous network.

In order better to combine with prior art; save cost; above-mentioned roaming method between heterogeneous networks; in described step (B1); bimodulus or the multimode terminal user user profile in various available mobile networks is accepted interface by the user profile of existing OSS (as 97 systems) and is saved in the Home Location Register.

Above-mentioned roaming method between heterogeneous networks, wherein, in the described step (B2), the type of location update message is by determining in the described location update message.

In location update message, the type of concrete network belonging is determined by the network type definition value, is example with GSM network and PHS network:

The MAP dialogue definition of GSM network:

MAP-DialogueInformation{

ccitt?identified-organization(4)etsi(0)mobileDomain(0)

gsm-Network(1)modules(3)map-DialogueInformation(3)version7(7)}

The MAP dialogue definition of PHS network:

MAP-DialogueInformat?ion{

ccitt?identified-organization(4)etsi(0)mobileDomain(0)

phs-Network(7)modules(3)map-DialogueInformation(3)version4(4)}

In above-mentioned two kinds of MAP dialogue definition, can see the concrete dialogue define grid type of GSM network: gsm-Network (1), promptly the network type definition value is 1; And the concrete dialogue define grid type of PHS network: phs-Netword (7), promptly the network type definition value is 7.Thus, can distinguish the type of two kinds of networks.

According to above-mentioned judgment mode, by that analogy, can determine other network types by the network type definition value.

Enforcement below in conjunction with Fig. 3,4 pairs of technical schemes is described in further detail:

1, implement scene of the present invention: the user realizes roaming by dual-mode handset between different mobile networks, see Fig. 3;

2, the user is saved among the ownership HLR by 97 systems in the information of the heterogeneous network of required roaming, comprises the essential information and the business information of the diverse network that needs roaming.For example, the user need roam in GSM network and cdma network, then needs information and the information in cdma network of user in the GSM network is saved among the ownership HLR in advance;

3, the user roams among certain mobile network, initiates location update message to HLR, wherein, includes the network type definition value, the present residing mobile network's type of described network type definition value respective user in the MAP dialogue definition in the described location update message;

4, HLR judges that according to the network type definition value in the location update message that receives this user roams mobile network's type at place at present;

5, HLR is according to mobile network's type of judging, and the network type that this user is present is updated to present residing mobile network's type in HLR;

6, follow-up mobile service is handled, and carries out Business Processing according to the corresponding mobile network's who preserves among the HLR information.

Concrete, suppose user's dual-mode handset support GSM network and cdma network, in advance essential information and the business information that in network terminal ownership HLR, can preserve this user GSM network and cdma network; Suppose that again the user is in cdma network at the beginning, mobile network's type of its mobile phone and network side is a cdma network; When the user when the cdma network border roaming is to the GSM network, the user initiates location update message to HLR, MAP dialogue definition in this location update message includes the network type definition value, mobile network's type that different network type definition value is corresponding different, because the network type definition value of GSM is 1, so the network type definition value that MAP dialogue definition comprises in the described Client-initiated location update message is 1; HLR receives location update message, and obtaining in the described location update message is 1 MAP dialogue definition value, and judges that thus the mobile network that this user roams the place at present is the GSM network; HLR mobile network's type that this user is present is updated to GSM from CDMA.
