"SHORT MESSAGE SERVICE NETWORK, SHORT MESSAGE PROVIDING METHOD AND SHORT MESSAGE SERVICE CENTER". A short message service (SMS) network (100) allows more than one short message service center (SMSC) (101,101 ') to serve an individual subscriber (104) without virtually any modification of existing conventional network elements, for example. for example, the home rental registry (HLR) (102) or the mobile switching center (MSC). In one described embodiment, the SMS network HLR 100 sends a notification, for example, an SMS notification signal (SMSNOT), to a predetermined 101 among the plurality of SMSCs 101, 101 'of the SMS network ( 100) when a subscriber (104) becomes available to receive a pending short message from at least one of the plurality of SMSCs (101, 101 '). Each of the plurality of SMSCs (101, 101 '), in turn, sends short messages to a desired subscriber (104), and then transmits the notification signal to one of the SMSCs (101'), until all SMSCs (101, 101 ') have sent their pending short messages. The next SMSC to which SMSNOT is transmitted can be fixedly determined (417), for example by means of a network configuration. In addition, the path for transmitting the SMSNOT signal 305 may be reconfigured when one or more SMSCs 101,101 'are added to the SMS network 100. Alternatively, the transmission path may be dynamically determined (416) via the preceding SMSC (101) according to a parameter-based smart rule such as, for example, the type of short message held by the SMSC. (101), desired subscriber address (104), desired subscriber type (104), etc. The trajectory can further be determined by a combination of fixed (417) and dynamic (416) selection. For example, the next SMSC selection (101 ') can usually be fixed (417), and after an event of a predetermined event occurs, dynamic selection (416) based on smart rules can be triggered.
