Embodiment Construction

[0040] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Throughout this description, like numbers refer to like elements.

[0041] As already discussed previously, figure 1 The different communication states and transitions between these states in an LTE / UMTS network are illustrated, with the UE between three different states in connected mode; CELL_DCH, CELL_FACH and URA_PCH, and idle state in idle mode convert. Inactivity in the connected state for a certain time (determined by a timer) generally results in a transition to a lowe...

Abstract

The invention relates to methods and device for detecting when a mobile terminal is in a state where it is incapable of replying to a message. In a first aspect of the present invention, it is provided a method of detecting, at a mobility node in a communications network, a state where a mobile terminal is incapable of replying to a message. The method comprises receiving (S101) the message from a gateway node, and determining (S102) whether the mobile terminal is incapable of replying to the message. Further, the method comprises sending (S103) a response to the gateway node indicating that the mobile terminal is not yet capable to reply to the message.

Description

technical field [0001] The present invention relates to a method and apparatus for detecting when a mobile terminal is in a state where it cannot reply to a message. Background technique [0002] In 3GPP wireless technologies, such as in Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), and Long Term Evolution (LTE), Radio Resource Control (RRC) protocols handle user equipment (UE) and radio access networks Layer 3 control plane signaling between the (RAN), ie the network between the UE and the core network. In UMTS, RAN is called UMTS Terrestrial Radio Access Network (UTRAN) and includes NodeBs and Radio Network Controllers (RNC), while in LTE, RAN is called Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) ) and includes an evolved NodeB (eNodeB). [0003] RRC protocols include, for example: [0004] · functions for connection establishment and release, [0005] Broadcast of system information, [0006] radio beare...
