Problems solved by technology

As shown in Table 1 above and Table 2 below, the use of a notification sequence appears to currently provide the best performance for false alarm probability, but the notification sequence method proposed in 3GPPR1-040536 requires some background processing and is thus Not optimal for battery life

Embodiment Construction

[0066] Exemplary embodiments of the present invention will be described with reference to the drawings, wherein like elements and structures are denoted by like reference numerals.

[0067] The present invention proposes a new method for multi-frame notification messaging based on cyclic transmission of notification coordinates. This method is hereinafter referred to as the "cyclic notification sequence method".

[0068] While the method according to the present invention can be applied to various wired and wireless networks requiring notification and having a framed data structure, an example for MBMS notification in UMTS, as defined in 3GPP, will be explained below, without loss of generality. Other applications utilizing other standard wired local area networks or wireless networks are possible. For example, notifications can be used to wake up devices on a wired LAN.

[0069] now refer to Image 6 , assuming that space 600 contains notification sequences of finite leng...

Abstract

A method for notification in communication systems is disclosed, in which a sequence of K notification indicators is assigned to a notification identifier like for example a MBMS service identifier or service group identifier of UMTS. The K notification indicators are transmitted one per frame in a cyclic manner. To obtain the notification indicator identifiers indexing the notification indicators in each frame, the plurality of notification identifiers is arranged in a K-dimensional space. Each of the K coordinates of this space can assume Nni values, where Nni is the number of notification indicators signalled per frame. The i coordinate Xi,n of the point to where the n notification sequence is mapped in the K-dimensional space, forms the identifier for the notification indicator belonging to the n notification sequence in the frame with the frame number satisfying the equation i = M mod K. <IMAGE>

Description

technical field [0001] The present invention relates to communication systems requiring notification of specific events to one or more receivers. In particular, the present invention relates to a multi-frame based notification procedure. Background technique [0002] In a network that does not have a dedicated connection to each individual device, the device must be notified of events such as incoming calls, incoming data, or requests for specific services when the device is in an idle state in which some of its functions are disabled. Data flows on the network are monitored at predetermined points in time for notifications telling them of any events on the network that require their attention. [0003] A common example of such a network is a wireless network, and especially a cellular network. As a specific example of a cellular network, UMTS will be explained in detail below. [0004] The paging procedure is one of the most fundamental procedures in a communication syst...
