Problems solved by technology

[0011] The techniques described in Tdoc S2-115461 and Tdoc S2-114349 still enable the UE to attempt to register on the CS domain, which can result in rejected registration attempts, increasing network signaling
Furthermore, the above-mentioned techniques are only valid when the UE's subscription becomes a PS-only subscription, i.e., the network operator cannot simply perform SMS handover over the PS domain in its 2G / 3G network and offload its CS domain to any existing subscription

Embodiment Construction

[0024] In this application, a wireless communication device is represented as a UE, but this is not intended to limit the wireless communication device to a device directly operated by a user (eg, a mobile phone). In this application, the term UE is intended to include all types of wireless communication devices, eg wireless communication devices adapted for so-called machine-type communication or machine-to-machine communication.

[0025] In some embodiments of the invention, the UE can advantageously provide that its registration in the CS domain is only intended for inclusion in or accompanying a registration request (e.g. for a combined registration of both the CS and PS domains) SMS instructions. In other embodiments of the invention, for example when the UE is to send SMS messages over the PS domain, the UE can advantageously change its traditional order of domain registration by performing PS domain registration before CS domain registration. In other embodiments of th...

Abstract

A wireless communication device may offer its registration in the circuit-switched domain of the network only for inclusion in a registration request (e.g. for a combined registration for both the CS domain and the packet-switched (PS) domain) or for short message service accompanying the registration request. instruct. When the device is to send SMS messages over the PS domain, the device can also change its traditional order of domain registration, for example by performing PS domain registration before CS domain registration. Before the UE attempts network registration, the device may indicate its intention to use or support SMS over PS domain and / or be notified of network support for SMS over PS domain.

Description

technical field [0001] The present invention relates to telecommunication systems, and more particularly to communication networks having a packet-switched domain and a circuit-switched domain capable of carrying short message service messages. Background technique [0002] As part of the work in Machine-Type Communications (MTC) (see e.g. 3GPP Technical Report (TR) 23.888V0.5.1, System Improvements for Machine-Type Communications (Release 10) (July 2010), 3rd Generation Partnership Project ( 3GPP) is addressing the need to provide services only on the Packet Switched (PS) domain. Such services may be referred to as PS-only services or PS-only features. [0003] In the course of this work, 3GPP Temporary Document (Tdoc) S2-115461 (Discussions and Conclusions about PS-Only) presented at TSG SA WG2 Meeting #88, 14-18 November 2011, San Francisco, CA Describes the draft architecture. These architectures include the following six requirements for PS-only features. [0004] 1....
