Signaling Probe Unit (SPU) delivers real-time, high-performance, high-density protocol monitoring in 3G mobile networks. The SPU enables applications to interrogate traffic between active signaling points in the network and trigger intelligent actions.
The SPU enables SS7 or RANAP messages carried over SCTP (IP) or MTP/MTP2 (TDM) to be monitored. SCTP/MTP messages from one or more Ethernet/E1 ports can be selectively passed to a user application in real time.
The advantage of the SPU is its powerful real-time monitoring capabilities. The SPU can monitor multiple Ethernet ports and/or TDM ports simultaneously. Users can choose which types of protocols to monitor, such as RANAP, SCCP, ISUP and more. The probe is configurable to immediately perform certain actions or send certain alerts to the user application in case it detects certain patterns of traffic, allowing networks to instantly react to issues in the network requiring immediate attention.
The SPU is a software probe, which can be installed on any standard physical server running linux or on any popular cloud service (virtual server). It can also be deployed in combination with E1/T1 PCIe cards, or an appliance – the TelcoBridges Tmonitor, in case the signaling is carried over E1/T1 or STM-1 interfaces
Network Performance Management
The SPU provides real-time monitoring, as well as detailed CDRs and xDRs, which allow network administrators to protect their network from failures, catch and fix problems in real time, and define rules that optimize network operation.
Missed call alert
This is an example of a value-added service that is enabled by the SPU – If a subscriber’s phone is out of reach or is turned off, and they receive a call during that time, they can get a message containing information on their missed calls once their phone reconnects to the network.
Location-based Services
When users move from one area to another in the mobile network, the SPU receives a location update. That location update can be used by marketers and advertisers to send customized messages to subscribers, promoting their business. For example, notifying subscribers of a clothing store sale nearby.
Welcome SMS
The probe can identify when roamers join the mobile network and can be programmed to trigger the sending of a welcome message to the new subscriber. networks can welcome users to their network, and provide them with useful information about the network, the country, emergency numbers, and more.
