Managing initial cell selection in a wireless communication network

摘要

Synchronization information and access node identification information are transmitted from a first access node and a second access node. It is determined that loading information of the first access node meets a first loading criteria and loading information of the second access node meets a second loading criteria. A message is transmitted from the first access node comprising the determination that the loading information of the first access node meets the first loading criteria and the loading information of the second access node meets the second loading criteria. The wireless device then determines the second access node identification based on the message and on the synchronization information. An access request is received at the second access node to initiate a communication session between a wireless device and the second access node.

1. A method of managing initial cell selection in a wireless communication network, comprising:
receiving at a wireless device synchronization information and access node identification information from a first access node and a second access node; receiving at the wireless device a message from the first access node comprising loading information of the first access node and of the second access node; determining at the wireless device that the first access node comprises a highest cross-correlation and that the second access node comprises a next highest cross-correlation based on the synchronization information and the access node identification, wherein the access node identification for each of the first access node and second access node is used to extract references sequences from the synchronization information such that the highest cross-correlation and next highest cross-correlation are determined based on the extracted references sequences; determining at the wireless device that the loading information of the first access node meets a first loading criteria and that the loading information of the second access node meets a second loading criteria; and sending from the wireless device to the second access node a request to initiate a communication session between the wireless device and the second access node based on the determined cross-correlations and the determinations that the loading information of the first access node meets the first loading criteria and that the loading information of the second access node meets the second loading criteria.
