0 Introduction p. 5
The present document captures the results of the feasibility study on Mobile data applications for GERAN.
1 Scope p. 6
The present document contains the results from the feasibility study on efficient support of mobile data applications for human communications in GERAN.
The following aspects shall be covered in the study:
- Analysis on relevant traffic profiles from GERAN perspective for the mobile data applications of human communications
- Analysis on the impacts on GERAN network based on the identified traffic profiles
- GERAN enhancements to alleviate these impacts with regards to: Radio resource utilization; signalling procedures; RR states and transition between them and Battery lifetime
- Common assumptions on simulations and evaluations for candidate solutions

4 Objectives p. 7
4.1 General p. 7
The general objectives of this study is to make the GERAN network better suited for mobile data applications used on multi-tasking capable mobile stations, e.g. IM chatting, HTTP/WAP browsing services (including streaming), social network services, etc , this study aims to consider the following objectives:
- Study and identify the relevant traffic profiles from GERAN perspective for the mobile data application of human communication, e.g. IM chatting, HTTP/WAP browsing (including streaming), social network service, etc.
- Study the impact on GERAN network based on the identified traffic profiles.
- Study enhancements to alleviate the impacts from these traffic patterns on the current GERAN networks (if any)
4.2 Performance Objectives p. 7
The candidate enhancements aiming at alleviating the identified impacts should consider the following performance objectives. When evaluating the candidate enhancements, the relative performance gains should be evaluated by comparing to the reference scenario for which the common assumptions are described in section 6.
- Improve radio resource utilization
- Reduce signalling procedures
- Minimize the impact on RR states and reduce the transition between them
- Reduce the impact on battery lifetime
4.3 Compatibility Objectives p. 8
The candidate enhancements aiming at solving the identified problems should consider the following compatibility objectives:
-
Avoid impacts on existing BTS and BSC hardware:
- This will enable use of already existing hardware and only require a software upgrade.
-
Be based on the existing network architecture and minimal impact on core network:
- This will enable an operator to re-use existing network nodes.
- Minimize the impacts on mobile station.
