Radio Access Technology Interworking

A wireless communications apparatus that facilitates radio access technology interworking, comprising:

• means for obtaining a channel list that includes channels associated with a target network;
• means for calculating a target channel;
• and
• means for retaining the target channel as prehash information, wherein the channel list is obtained from a source network.

A computer program product, comprising:

• a computer-readable storage medium comprising:
• a first set of codes for causing a computer to receive a channel list from a source network, wherein the channel list includes channels associated with a target network;
• a second set of codes for causing the computer to calculate a target channel as a function of the channel list;
• and
• a third set of codes for causing the computer to store the target channel as prehash information.

At least one processor configured to transition between radio access technologies, comprising:

• a first module for receiving a channel list from a source network, wherein the channel list includes channels associated with a target network;
• a second module for calculating a target channel, wherein the target channel will be read after the transition to the target network occurs;
• and
• a third module for storing the target channel that needs to be read as prehash information.

A method utilized in a wireless communications environment, comprising:

• employing a processor executing computer executable instructions stored on a computer readable storage medium to implement following acts:
• detecting a mobile device has entered a target network, wherein the mobile device has recently left a source network;
• generating an indicator that includes an identity of the mobile device;
• and
• sending the indicator to the source network, wherein the indicator triggers a suspend control on the source network.

A wireless communications apparatus that supports radio access technology interworking, comprising:

• means for determining a mobile device has left a source network and entered a target network;
• means for creating an indicator that includes an identity of the mobile device, wherein the target network and the source network support different radio access technologies;
• and
• means for conveying the indicator to the source network, wherein the detecting the mobile device has entered the target network comprises recognizing the mobile device has performed a registration, an origination, or a page request on the target network.
