| 20110009145 | METHOD AND NETWORK ARRANGEMENT FOR RE-ALLOCATING FREQUENCY RESOURCES BETWEEN CO-LOCATED CELLULAR NETWORKS - The invention relates to a method and a network arrangement for re-allocating frequency resources for terminal devices of co-located cellular networks. The co-located cellular networks can temporally release at least a part of their frequency resources at another cellular network's disposal. For accomplishing the reallocation cellular terminals camping in these co-locating cellular networks utilize in their access bursts a complementary code set. The complementary code set can comprise an operator specific signature and a terminal device specific signature. Each of the co-located networks can by correlation identify also terminal devices of other co-locating cellular networks. If the serving cellular network has exhausted its frequency resources it can ask additional frequency resources from the other co-locating cellular networks. | 01-13-2011 |
