MCORE: a context-sensitive recommendation system for the mobile Web

EXPERT SYSTEMS, Issue 1 2007
Joon Yeon Choi
Abstract: Recommendation systems for the mobile Web have focused on endorsing particular types of content to users. Today, mobile service providers have a more direct recommendation channel, namely the short messaging service. Therefore, mobile service providers should consider both the timing and context of recommendation messages (push messages) that are sent to users. Mobile service providers can learn context-specific user preferences by analysing mobile Web use logs and user responses to push messages. In this paper, we present a context-sensitive recommendation system that can be used to select the optimal context in which to send recommendation messages. We call this system the mobile context recommender system (MCORE). We compared user responses to push messages delivered in and out of suitable contexts as determined by MCORE. The precision of push messages delivered within a suitable context was higher than that of messages delivered outside of one. [source]

Implementation solutions for the interworking between MMS and streaming

INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 10 2003
Miraj-E-Mostafa
Abstract Multimedia messaging service (MMS) and streaming are forerunner multimedia applications in mobile communication. Use of streaming in the retrieval of continuous multimedia content of MMS is the identified optimum scope (extent) of interworking between MMS and streaming. The optimum interworking can remove a limitation visible in MMS,retrieving content requiring more storage space than available in a mobile terminal. This paper presents two different solutions for implementing the interworking. The implementation solutions are consistent with the existing mobile frameworks and the working principles and procedures of both MMS and streaming. Consistency is very important here not only to avoid creating isolated solution, but also to preserve user experience. This paper describes in detail how each of the solutions operates, including the process of using streaming in the MMS retrieval. Pros and cons of both the solutions are also analysed to compare those. Other important factors tackled in the analysis are implementation flexibility, complexity, terminal capability indication, and content adaptation. Copyright © 2003 John Wiley & Sons, Ltd. [source]

Aftercare intervention through text messaging in the treatment of bulimia nervosa,Feasibility pilot

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 8 2006

Abstract Objective: Even with the best available treatment, most bulimia nervosa (BN) sufferers are not symptom free at the end of therapy and, for those who have achieved remission, risk of relapse is high. Thus, there is a need for aftercare or relapse prevention interventions after therapy. It is not yet known what type of intervention should be delivered, and how to suit patient needs while being mindful of cost and time constraints of service providers. This pilot study was conducted to explore the feasibility, acceptability, and efficacy of a text messaging (short messaging service [SMS])-based intervention in the aftercare of BN patients who had received outpatient psychotherapy. Method: A total of 21 patients with BN participated in the 6-month SMS-based intervention as a step-down treatment AFTER outpatient therapy. Results: Levels of use of the program were relatively low and attrition high, indicating limited acceptance of the intervention. Conclusion: This study suggests that the SMS-based intervention would benefit from further adaptation to make it a more useful tool for the aftercare of patients after outpatient treatment for bulimia nervosa. © 2006 by Wiley Periodicals, Inc.

Advanced IMS client supporting secure signaling

BELL LABS TECHNICAL JOURNAL, Issue 4 2008
Ramana Isukapalli
With recent advances in core and access networks and the availability of increased bandwidth and sophisticated devices for end users, there is an increased demand for client applications running on mobile devices, such as laptops and handheld devices, to support real time applications like Voice over Internet Protocol (VoIP) and streaming video, apart from traditional applications like web browsing. This paper presents a prototype IP Multimedia Subsystem (IMS) client, which serves as a VoIP client to set up calls between Internet Protocol (IP) devices and interworks with circuit-switched networks to deliver calls to public switched telephone network (PSTN) phones. It implements supplementary services (including call waiting, call transfer, and call forwarding); supports multimedia ringing, short message service/multimedia messaging service (SMS/MMS), audio/video conferencing, and peer-to-peer video; and it can deliver a call to a user (as opposed to a device) by simultaneously ringing multiple devices registered by the user. Further, to address various security concerns, the client supports Hypertext Transfer Protocol (HTTP) digest authentication using Message Digest 5 (MD5) cryptographic function authentication and key agreement (AKA) and can create secure tunnels to the core network using IP security (IPsec). © 2008 Alcatel-Lucent.
