The Access Network Discovery and Selection Function (ANDSF) framework was introduced first in 3GPP Release 8 to standardize operator policy mechanism and since then it has evolved in the standard to provide further enhancements like flow mobility and more specific traffic identification. 3GPP Release 8 In Release 8, the ANDSF framework provides access network information; for instance, leveraging Wi-Fi Access (more ..)
Rollout of LTE over a legacy 2G/3G network for IMS-based VoIP service using Single Radio Voice Call Continuity (SRVCC). Single Radio Voice Call Continuity (SRVCC) can simplify rollout of a new LTE network consider an operator who has decided to move voice services to VoIP over IMS in conjunction with the deployment of an LTE access network. In the absence (more ..)
Mobile internet and in particular the wireless network will evolve hundred-fold in next ten to fifteen years. To cope with the changes ETSI Future Mobile Summit discussed how 3GPP systems will ensure future stability as the network copes with an explosive growth in complexity and usage. With 3GPP providing the evolutionary framework for mobility, via its Releases of new functionality (more ..)
In the recent releases 3GPP has focused on enhancing the efficiency of high speed channels leading to significant network data capacity gain. It is also widely beneficial for operators to enhance the link efficiency of DCH for certain services leading to a further improvement in network data capacity. For example the DCH is still a very attractive option to serve (more ..)
In my last blog I wrote about how Scalable UMTS works and to make the things more clear here is a video demo from Qualcomm. The video demonstrate how scalable UMTS works and what one will expect as a end user from this new technology.
Justification is that only a 5 MHz channel bandwidth is defined for UMTS FDD; this restriction may limit the deployment of UMTS in the case when the spectrum allocation is less than 5 MHz, or not a multiple of 5 MHz. An example of such a case is when frequency resources are re-farmed from legacy systems. A new 3GPP study (more ..)
Qualcomm is big name in wireless modem and complete mobile solutions, but producing wearable devices are definitely a new challenge for the company. Lately almost all mobile phone and consumer electronics companies shown their interest in Smart Watch business. SONY was the first one to bring in such a wearable device in the form of SmartWatch brand name and followed (more ..)
