Interconnection Issues in a Multivendor Enviroments
Problems associated with a Multi-vendor Environment and How to deal with it in a Cellular Network. In today’s networks, whether GSM, WCDMA and CDMA whether it is 3G or 2G, there are a number of challenges arising when a particular operator chooses multiple vendors to supply its telecoms equipment. Ideally, there should be a smooth and seamless interconnection amongst the vendors going by the standardization of almost all the interfaces. In practice, this seamless interconnection faces a number of challenges which I intend to discuss here. I will like to categorize these problems as arising from 1. A interface problems 2. MSC-MSC connection problems 3. IN problems 4. HLR issues A- Interface Problems When vendor A’s MSC connects to Vendor B’s BSC a number of issues arise from this connection. Ordinarily, the A interface is a standard interface and this should not pose a problem at all. But there exist some. Below is a typical GSM network and I will use this for this discussion. A typical...
