Authenticating between a CDMA network and a GSM network
First Claim
1. A general global gateway (GGG) comprising:
- a database configured to store a number of times the mobile station has accessed the GGG, the GGG being configured to support communication between a GSM network and an unmodified CDMA network to enable a mobile station (MS) subscribed in the GSM network to communicate using the CDMA network; and
a logic unit configured to execute program logic to determine whether a parameter is received from the MS, the parameter representing a count of a predetermined event that is a mutually agreed upon event between the GGG and MS,wherein, when the MS is a CDMA mobile station with a subscription in the GSM network, the GGG acts as an authentication controller in the unmodified CDMA network during registration of the MS but authenticates the MS using the GSM authentication mechanism; and
wherein the MS is placed in a short message service (SMS) only status during authentication.

Abstract
A general global gateway (GGG) permits authenticating between a CDMA network and a GSM network such that a mobile station having a subscription in a GSM network can roam into a CDMA network and be authenticated to use the CDMA network. The GGG obtains authentication parameters from the mobile station and determines whether the authentication parameters satisfy GGG authentication criteria. During the authentication process, the mobile station is placed in “SMS only” status until authorized by the GGG. Checks are made during the authentication process to assure the GGG and mobile station agree on the number of GSM network accesses and to assure the mobile station is authorized for GSM access for a time period.

7. A general global gateway (GGG) configured to support communication between a GSM network and a CDMA network to enable a mobile station (MS) subscribed in the GSM network to communicate using the CDMA network, comprising:
-
means for storing a number of times the MS has accessed the GGG; and means for executing program logic to determine whether a parameter received from the MS, the parameter representing the number of times the MS has accessed the GGG, is equal to the stored number of times the MS has accessed the GGG, wherein, when the MS is a CDMA mobile station with a subscription in the GSM network, the GGG acts as an authentication controller in the unmodified CDMA network during registration of the MS but authenticates the MS using the GSM authentication mechanism; and wherein the MS is placed in a short message service (SMS) only status during authentication. - View Dependent Claims (8, 9, 10, 11)

12. A method of wireless communications between a GSM network and a CDMA network to enable a mobile station (MS) subscribed in the GSM network to communicate using the CDMA network, comprising:
-
storing a number of times the MS has accessed a general global gateway (GGG); and determining whether a parameter received from the MS, the parameter representing the number of times the MS has accessed the GGG, is equal to the stored number of times the MS has accessed the GGG. wherein, when the MS is a CDMA mobile station with a subscription in the GSM network, the GGG acts as an authentication controller in the unmodified CDMA network during registration of the MS but authenticates the MS using the GSM authentication mechanism; and wherein the MS is placed in a short message service (SMS) only status during authentication. - View Dependent Claims (13, 14, 15, 16, 20)

17. Computer readable media embodying a program of instructions executable by a computer program to perform a method of wireless communications between a GSM network and a CDMA network enabling a mobile station (MS) subscribed in the GSM network to communicate using the CDMA network, the method comprising:
-
storing a number of times the MS has accessed a general global gateway (GGG); and determining whether a parameter received from the MS, the parameter representing the number of times the MS has accessed the GGG, is equal to the stored number of times the MS has accessed the GGG, wherein, when the MS is a CDMA mobile station with a subscription in the GSM network, the GGG acts as an authentication controller in the unmodified CDMA network during registration of the MS but authenticates the MS using the GSM authentication mechanism; and wherein the MS is placed in a short message service (SMS) only status during authentication. - View Dependent Claims (18)
