“…However, this still provides a wide range of services and selection for end users of telecommunication systems. Direct signaling systems could also be applied in several other environments, such as broad-band ISDN [1], mobile environments, or packet phone environment. Typical services in these environments must be examined to determine the usefulness of direct signaling services in these cases.…”

“…Because the signaling service provider is chosen independently of the transport service provider, the originating call server cannot derive the called party call server from the dialed number. In [1], several possible solutions to this problem are proposed, including modifying the numbering scheme used in telecommunication networks, or maintaining shared databases from which the originating call servers can obtain call server identifiers for called parties.…”

“…Interactions between the BCM and the service logic programs often constitute message exchanges between processors on the switch and other intelligent processors in the network called service control points (SCP's). 1 Services can be classified into two broad categories: those that modify the information or format of the information exchanged between subscribers and the network, and those that modify the resources used for communication purposes. For example, the distinctive ring and number translation services, such as speed dial and 800-number services, only affect the information exchanged by the user and the network.…”

“…From [11], the mean sojourn time in a round-robin processor-sharing queueing system is (1) where is the mean service time and is the processor utilization. In a multiclass system with message types, the mean service time is given by (2) where is the arrival rate of message type , is the total arrival rate of all messages, and is the service time of message type .…”

“…It also Manuscript limits competition among service providers. In [1], a new access signaling architecture is proposed, called direct signaling, that allows signaling information to be routed and processed independently of transport information. This approach allows subscribers to choose to receive signaling services from one of many service providers.…”

In current telecommunication networks, the valueadded services available to subscribers are almost exclusively offered by the carrier providing local telephony service. This results from two factors: the processing for services is either based in or triggered from software executing on the access telecommunication switches, and signaling links over which subscribers request services are terminated on these access switches. In a direct signaling system, the signaling link from a subscriber does not necessarily terminate on an access switch, but rather on an intelligent server we call a call server. The call server invokes service functions and coordinates their interactions. This direct signaling system may be overlaid on various types of access networks, including circuit-switched telephony, packet telephony, wireless local loop, cable, etc. In this paper, we discuss the design, implementation, and performance of a direct signaling system, including procedures that provide varying amounts of integration with current telecommunication systems. Our results show that a direct signaling system using a low-delay direct signaling link and in which no changes are made to existing telecommunication switches incurs approximately 100 ms higher postdial delay than a standard ISDN system. A direct signaling system in which telecommunication switches provide open interfaces and coordinate processing with direct signaling servers incurs approximately 100 ms lower postdial delay than a standard ISDN system.
