bor cell lists. 3GPP LTE system information can be classified into two distinctive groups: static and flexible. The static part is sent more frequently, e.g., once per frame, in the cell and has a limited capacity for information transfer. The flexible part has a flexible amount of scheduled resources available, and thus encompasses most of the SI information. The flexible part has different types of Information Elements which require inde- pendent scheduling in order to allow sufficiently fast reception and efficient resource utilization. 4.6.2 Connected Mode Mobility In RRC_CONNECTED state, the network controls the UE mobility, i.e., the network decides when and where the UE should initiate handover process. For network-controlled mobility in RRC_CON- NECTED state, the network triggers the handover process based on radio conditions or network load. To facilitate this process, the network may configure the UE to perform measurement reporting (including the configuration of measurement gaps). The network may also initiate handover blindly, i.e., without having received measurement reports from the UE. Before sending the handover message to the UE, the source eNB prepares one or more target cells. The target eNB generates the message that is used to perform the handover, i.e., the message including the access stratum configuration to be used in the target cell. The source eNB transparently (i.e., it does not modify values or content) forwards the handover information received from the target to the UE. When appropriate, the source eNB may initiate data forwarding for (a subset of) the data radio bearers. After receiving the handover message, the UE attempts to access the target cell at the first available random access channel opportunity according to random access resource selection, i.e., the handover is asynchronous. Consequently, when allocating a dedicated preamble for the random access in the target cell, E-UTRA ensures it is available from the first random access opportunity that the UE may use. On successf
