Embodiment Construction

[0117] Before proceeding with additional description of the problems and the solutions in this paper to those problems, refer to figure 1 , which shows a block diagram of an example system in which the example embodiments may be implemented.

[0118] figure 1 A block diagram of an exemplary wireless network in which the present invention is used is illustrated, showing 3 systems, each with a different radio access technology: E-UTRAN 101 , UTRAN 102 and GERAN 103 . Each of these systems is roughly divided into a radio access network (RAN) 115 and a core network (CN) 130 . For ease of explanation, do not discuss figure 1 Many connections between various entities in . Furthermore, systems 101, 102, and 103 are shown for ease of illustration only, and not for limitation or exhaustion.

[0119] In an E-UTRAN embodiment, the RAN 115 includes an eNB (Evolved Node B, also known as an E-UTRAN Node B) 120, the CN 130 includes a Home Subscriber Server (HSS) 133, a Serving Gateway (S...

Abstract

A network element of a first radio access technology system receives scheduling information for using resources in a second radio access technology system. Based on the scheduling information for using the resources in the second radio access technology system, the network element of the first radio access technology system is scheduled to use the resources in the second radio access technology system. The network element of the first radio access technology system transmits utilizing the resources in the second radio access technology system. Further aspects provide for scheduling based on building an interference profile map of the second radio access technology system created from the scheduling information. Other aspects detail additional attributes to determine the scheduling and / or go into or augment the interference profile map so as to determine the scheduling.
