We consider the services of broadcasting short messages via forward signaling channels in wireless cellular networks. In the provision of such services, the negative effect of short messages on the delivery of delay-sensitive control messages must be restricted. On the other hand, it is desirable to accommodate the users' demands for service enhancements involving timeliness and informativeness. As a way to resolve such conflicting arguments, we present a generic scheme in which a short message may be rejected or removed according to the buffer occupancy at the base station and is split into a number of segments for the transmission across a forward signaling channel. However, the rejection, removal and segmentation exhibit a trade-off among several facets of service enhancements. Thus, for a quantitative evaluation of the scheme and efficient optimization of design parameters, we develop an analytical method to calculate the moments of delay times experienced by control and short messages at a base station. Using the analytical method, we investigate the delay and loss performance of control and short messages with respect to the message load and short message length.
