Cellular radio network A cellular radio network of an MSC/MSS is a geographical area where the MSC/MSS provides GSM or UMTS radio access. Cell Cells are the basic units in a GSM cellular radio network. A cell is a geographical area that is covered by a transceiver. A base transceiver station (BTS) network element generally controls several cells. In cellular radio network configuration management in the MSS, the term "BTS" is considered one cell.</p> <p>Figure 1.</p> <p>Cells</p> <p>12 (91)</p> <p># Nokia Siemens Networks</p> <p>DN9797631 Issue 8-1 en</p> <p>Cellular radio network management</p> <p>Service area Service areas are the basic units of a UMTS cellular radio network. A service area is a geographical area covering one or more UMTS cells. UMTS cells are not defined in the cellular radio network configuration of the MSS. Service areas connected to an MSS through MGW Rel-4 have an LA-service area relation.</p> <p>LA 2</p> <p>SA 7 SA 7LA 1</p> <p>SA 2 SA 1 SA 3LA 3</p> <p>SA 5 SA 4 SA 6</p> <p>Figure 2.</p> <p>Location areaservice area relation</p> <p>Location area A location area (LA) consists of one or more adjacent cells in a GSM network, or one or more service areas in a UMTS network. User equipment/mobile stations can roam inside an LA without having to perform location updates. LAs in GSM and UMTS networks have the same parameters.</p> <p>DN9797631 Issue 8-1 en</p> <p># Nokia Siemens Networks</p> <p>13 (91)</p> <p>Cellular Radio Network Management</p> <p>NoteIf either one of Features 1449 or 1564 is activated, then the Location Areas for UMTS/GSM must be defined separately. If both Features 1449 and 1564 are activated, this is not needed. You can check the LA's UMTS/GSM access with the ELL command.</p> <p>LA9 LA6 LA1 LA4 LA7 LA3 LA2 LA8 LA5</p> <p>Figure 3.</p> <p>Location areas</p> <p>A network can include its own LAs, network LAs (addresses of LAs controlled by other MSC/MSSs), and auxiliary LAs (in UMTS networks only). UMTS/GSM access In the multipoint Iu/A concept, you need to be able to determine whether your system has UMTS/GSM access. Even though a Location Area can include both GSM cells and UMTS service areas, it is recommended that Location Areas would be defined and used separately for the UMTS and the GSM, so that a single LA would only have either UMTS service areas or GSM cells connected to it. MSC/VLR area The network's own LAs, belonging to the same MSC, form an MSC/VLR area. An MSC/VLR area can consist of one or more LAs, the size of which is decided in network planning. The trade-off in the LA size is that small LAs require more location updates from user equipment/mobile stations, which means an increased signalling load. Large LAs require more paging procedures, which means an increased load on the BSS/RNS air interface.</p> <p>14 (91)</p> <p># Nokia Siemens Networks</p> <p>DN9797631 Issue 8-1 en</p> <p>Cellular radio network management</p> <p>LA9 LA7 LA4 LA2 LA5MSC/VLR</p> <p>LA3</p> <p>LA1</p> <p>LA8 LA6</p> <p>Figure 4.</p> <p>MSC/VLR area</p> <p>Pool area A pool area corresponds closely to an MSC/MSS service area. The main difference is that a pool area is served by multiple MSCs/MSSs simultaneously. The radio network configuration concerning the pool area must be identical in every MSS controlling the pool area. The traffic is shared between the MSSs within the pool area and a mobile station can roam within the pool area without having to change the serving MSS. Another difference between a pool area and a service area is that pool areas may overlap, whereas service areas cannot.</p> <p>DN9797631 Issue 8-1 en</p> <p># Nokia Siemens Networks</p> <p>15 (91)</p> <p>Cellular Radio Network Management</p> <p>LA12 LA3 LA1 LA9MSC/VLR 1 LA4</p> <p>LA6 LA8 LA10</p> <p>MSC/VLR 2 MSC/VLR 3 LA5</p> <p>LA...</p>
