Abstract
A single CDMA radio access network is used in conjunction with both a GSM core and an IS-41 core using a hybrid MSC to support mobile stations having subscriptions in either the GSM core or IS-41 core without requiring more than a single subscription.
Claims27
A mobile switching center (MSC) configured for supporting wireless communication between a code division multiple access (CDMA) radio access network (RAN) and both a GSM core infrastructure and an IS-41 core infrastructure, comprising:
- a first circuit communicating with the CDMA RAN, the first circuit communicating with the IS-41 core infrastructure using IS-41 protocol;
- and
- a second circuit communicating with the CDMA RAN, the second circuit communicating with the GSM core infrastructure using GSM protocol.
A state machine mobile switching center (MSC) configured for supporting wireless communication between a code division multiple access (CDMA) radio access network (RAN) and both a GSM core infrastructure and an IS-41 core infrastructure, comprising:
- a state machine selectively configurable to communicate with the IS-41 core infrastructure using IS-41 protocol or with the GSM core infrastructure using GSM protocol, based on at least one identifier received from at least one MS.
A communication system, comprising:
- a CDMA RAN;
- a GSM core infrastructure;
- a CDMA core infrastructure;
- and
- an MSC interconnecting the CDMA RAN with both infrastructures.
A method for effecting communication with a first wireless mobile station (MS) having a subscription in a GSM core infrastructure and with a second wireless MS having a subscription in a CDMA infrastructure without requiring either MS to have more than a single subscription, comprising:
- receiving, at an MSC, at least one identifier from at least one MS;
- based on the identifier, determining the core infrastructure in which the MS has a subscription;
- undertaking, through the MSC, authentication with the MS using information from the core infrastructure in which the MS has a subscription;
- and
- collecting accounting data using the core infrastructure in which the MS has a subscription.
A mobile switching center for a wireless communication system, comprising:
- means for receiving an identifier from an MS;
- means for using the identifier to determine whether the MS has a subscription in a GSM core infrastructure or a CDMA core infrastructure;
- and
- means for communicating with both core infrastructures.
A wireless mobile station (MS), comprising:
- at least one storage device including an identifier;
- at least one radio communicating the identifier to a CDMA radio access network (RAN);
- and
- one and only subscription in a GSM core infrastructure.
