Problems solved by technology

Add the queuing time obtained from the short messages SM n-1, SM n-2, etc. previously stored in the queue to the transmission time of the most recent short message SM n, if this value exceeds the maximum time defined by the above-mentioned time monitoring , the business center SC does not receive confirmation during this time monitoring period, which will cause various problems

Embodiment Construction

[0038] exist figure 2 and image 3 , the service center SC sends a short message via the gateway mobile services switching center GMSC to the mobile switching center MSC of the B-subscriber MS whose location area visitor location register is connected to the MSC. The invention is used in the situation where the previous short message is being sent from the switching center MSC to the B-subscriber's mobile station MS. The queuing control management QCM of the exchange MSC then determines the estimated total delay of incoming short messages. The total delay includes the queuing time and the transmission time of the relevant short message SMn, wherein the queuing time is the time required to send the short messages SMn-1, SMn-2... stored in the queue MM. This total delay can be defined so that, for example, for each short message SM n-1, SM n-2 ... in the queue MM and for the short message SM n currently arriving at the exchange MSC, a message-specific partial delay is calculat...

Abstract

The invention relates to a method of processing such a short message arriving at a mobile switching centre of a cellular radio network which arrives at the same time as a preceding short message is being sent from the mobile switching centre ot a B-subscriber. In addition, the invention relates to a mobile switching centre of a cellular radio system implementing the method. When a short message (SM n) addressed to a B-subscriber (MS) arrives at a mobile switching centre (MSC) at the same time as previously arrived short messages (SM n-1...) are being sent to the B-subscriber, then the exchange (MSC) stores the newest short message in a queue. A problem arises when the total delay of the queue is longer than the maximum time, defined by time supervision, used on a connection between the exchange (MSC) and a service centre (SC). To avoid exceeding the time supervision, the total delay of an incoming short message is estimated, the total delay comprising a queuing time resulting from the preceding short messages and the actual transmission time of said short message. If the total delay is longer than the maximum time, the incoming short message is not stored in a queue, but a negative acknowledgement is sent to the service centre (SC), on account of which it will send the short message again after a certain time.

Description

technical field [0001] The invention relates to a method for processing short messages arriving at a mobile switching center of a cellular radio network at the same time as the current short messages are being sent from the mobile switching center to a B-subscriber. The invention also relates to a mobile switching center of a cellular radio system for implementing the method. Background technique [0002] Figure 1 shows the components of a cellular mobile system necessary for the invention. The mobile station MS communicates with the base transceiver station BTS serving the cell Cn. The base transceiver station is connected to the mobile switching center MSC via the base station controller BSC. The subsystem controlled by the base station controller BSC is called the base station subsystem BSS, which subsystem includes the base transceiver station BTS controlled by it. The interface between the exchange MSC and the base station subsystem BSS is called the A interface. ...
