Abstract
A method and apparatus for allowing a dual-mode mobile device to communicate with a CDMA network without switching from an OFDMA network are provided. For certain embodiments, an OFDMA gateway component may serve as an interface between the OFDMA network and CDMA network, detecting a CDMA message targeting the mobile device and, in response, generating an OFDMA message containing information regarding the CDMA message.

A method for communicating with a multi-mode mobile device that supports code division multiple access (CDMA) and orthogonal frequency division multiple access (OFDMA) communications, comprising:
- monitoring a mobile switching center (MSC) of a CDMA network directly for a CDMA paging request targeting the mobile device;
- and
- in response to detecting the CDMA paging request targeting the mobile device, notifying the mobile device of the CDMA paging request with an OFDMA message by transmitting an OFDMA page request to an OFDMA base station servicing the mobile device, wherein the transmitted OFDMA page request format is modified to include CDMA paging request information.
A method for communicating with a multi-mode mobile device that supports code division multiple access (CDMA) and orthogonal frequency division multiple access (OFDMA) communications, comprising:
- monitoring a mobile switching center (MSC) of a CDMA network directly for a CDMA paging request targeting the mobile device;
- and
- in response to detecting the CDMA paging request targeting the mobile device, notifying the mobile device of the CDMA paging request with an OFDMA message by transmitting an OFDMA de-register request to an OFDMA base station servicing the mobile device.
