Systems, methods, apparatuses, and computer program products for supporting wireless emergency alert messages sent to mobile devices through radio access networks are provided. One method may include utilizing a binary value of 0000 as an update number in wireless emergency alert messages that have short text, utilizing a binary value of 0001 as the update number in wireless emergency alert messages that have long text, broadcasting the short text wireless emergency alert message to mobile devices on a second generation or third generation (2G/3G) network, and broadcasting the long text wireless emergency alert message to mobile devices on a long term evolution (LTE) network.

Methods and apparatuses for supporting wireless emergency alert messages

A method may include determining, by a base station, a switching occasion during which at least one connected user equipment will be in a connected off cycle and at least one idle user equipment will be in an idle off cycle, instructing the at least one connected user equipment and at least one idle user equipment to switch, during the switching occasion, from communicating with the base station via a source carrier frequency to communicating with the base station via a target carrier frequency, and switching, during the switching occasion, from communicating with the at least one connected user equipment and the at least one idle user equipment via the source carrier frequency to communicating with the at least one connected user equipment and the at least one idle user equipment via the target carrier frequency.

The present embodiments address the need for an apparatus and method that provides additional orthogonal codes without trading off RF capacity. When a system is operating near its RF capacity and running out of available orthogonal codes, one or more channels are allocated using a new radio configuration () that utilizes longer orthogonal codes. This new radio configuration increases the number of available orthogonal codes without sacrificing RF capacity. Instead, it reduces the peak data rate such a channel can provide.
