Will Mobile Operators Face a Capacity Crunch Soon?

By Richard Kinder
VP of Technology and New Business for Europe

Mobile data has finally arrived. After years of hype, the volume of data on mobile networks is reported to have surpassed that of voice traffic. Whilst the majority of this traffic is driven by people with mobile broadband subscriptions, undoubtedly the new breed of data-intensive mobile devices contributes significantly to this rapid growth. This bandwidth consumption is stressing the edge of the network and backhaul, resulting in a potential field day for providers of optical and microwave infrastructure. I could successfully argue that the capacity crunch is already upon us.

A frequently cited answer to congestion problems is to off-load mobile data from the mobile core network. Various techniques may be deployed to achieve this, such as WiFi or Femtocell offload. For the best results, both approaches rely on mobile devices being aware of their network context and acting accordingly. Unfortunately, the majority of handset software platforms have yet to acquire the necessary smarts to make best use of these whilst staying within the strict energy budgets imposed by today’s battery technologies.

We should not forget that bandwidth usage is only one metric by which to measure mobile network capacity. As has been highlighted in numerous articles, blogs and elsewhere during and since Mobile World Congress 2010, today’s mobile devices also impose a greater signalling burden on the mobile network. Whilst I am yet to receive a clear explanation of exactly what signalling traffic is generated, one can hypothesise that the desire to preserve battery life results in these devices frequently establishing and tearing down PDP contexts, which in turn creates signalling traffic within the operator’s infrastructure.

So what can the industry do about this? 4G standards such as LTE and WiMAX eventually will allow for future growth in mobile data usage – the key word being future! Prior to the halcyon days and unlimited bandwidth of 4G, network operators are committing significant amounts of money to enhancing their existing 3G infrastructure. As developers of device software, we too have a role to play, for example:
  • Consider the requirements of least-cost (to the network) routing balanced with least-energy routing. How many device TCP/IP stacks have actually been designed to take into account the vagaries of mobile data? Is inheriting networking stacks from desktop platforms acceptable?
  • 3G networks perform best (data transfer per mW is one measure) when communications are less “bursty” and the full bandwidth of the air interface is utilised at once rather than in dribs and drabs. Consider how this can be accommodated in client / server interactions.
  • Be efficient in the use of data. For example, why send a full software update over the air when a binary difference can be used instead (Red Bend Software Ltd might be able to help you here!)
We cannot rely solely on network operators’ investments in infrastructure to address the capacity crunch. We have a responsibility to use what they provide as efficiently as possible. Services and platforms that can help operators manage their capacity concerns just may be more appealing to them.

To misquote Scott McNealy (he of “the-network-is-the-computer fame”), one day datatone will be as important as dialtone. That day is here.

Red Bend Enables China Mobile to Manage Android Devices

By Seger (Gang) Shen
Sales Director for China,
Red Bend Software

3G has arrived in China, and with it has come a wave of innovative handsets. To drive usage of its new 3G service, China Mobile has developed an exciting new Android-based software platform called the OPhone OS (Open Mobile Phone Operating System). The OPhone OS has been developed by Borqs for China Mobile and is quickly expanding to Japan and other regions. OPhone smartphones are designed to compete with Apple’s iPhone, which is being offered by China Unicom.

Through an agreement with China Mobile Research Institute, Red Bend is enabling China Mobile to manage its Android-based devices by providing FOTA and DM software for the OPhone OS. Devices running OPhone, such as the HTC Dopod A6188, have already launched in the Chinese market.

3G devices are feature rich, and therefore more complex. When developing the OPhone OS, China Mobile and Borqs decided to build in management support to ensure that the platform could be easily and efficiently updated over the air with the latest features and software improvements.

“At Borqs, we understand that mobile phones and the software on these phones need to be updated at any time, from anywhere, and we needed a solution that could do this,” said Bob Li, senior vice president of business development at Borqs. “While the hardware of a phone can last for a long time, this is not the case with the software. Software comes with many functions and applications that require updates.”

According to Li, “Red Bend has a good history, and the company has many global customers and a great deal of support experience. I believe Borqs will maintain our partnership with Red Bend into the future, and I’m sure we will have many opportunities to work with them.”
