Techniques for deriving message counts based at least in part on a locally stored message count and at least a portion of a message count received from a remote network node are disclosed. The message counts can relate to downlink (DL) non-access stratum (NAS) counts. In one aspect, a device can receive a number of least significant bits of the DL NAS count in a handover message. The device can derive a DL NAS count by utilizing a remaining portion of most significant bits of a locally stored DL NAS count, and can determine whether to increment or decrement the most significant bits based at least in part on a parameter to handle cases where the least significant bits of the locally stored DL NAS count have wrapped due to overflow and/or underflow.

Determining a non-access stratum message count in handover

Systems and techniques are disclosed relating to communications. The systems and techniques include receiving an origination request for a call, determining whether the call is allowed on each of a plurality of wireless networks as a function of the origination request, and originating the call over a network selected from a plurality of networks. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.
