A relative time difference is determined between a positioning reference cell and at least two other detectable positioning cells. A reference signal of a positioning cell is detected to determine timing of a detectable positioning cell by either applying sliding window approach to acquire the positioning cell or a single window approach to track the positioning cell.

A single window approach is applied to track the positioning cell when a coarse timing of the positioning cell has been achieved or when the search window is not larger than a capture range capability of the mobile device.

In particular, a robust header compression (RoHC) profile can be defined for general packet radio service (GPRS) tunneling protocol (GTP) headers.

However, the second duplexer is configured to provide a second phase shift that is differential to the first phase shift from the transmission port to the receive port. By providing the second phase shift so that the second phase shift is differential to the first phase shift, the RF duplexing device can provide isolation through cancellation without needing to introduce significant insertion losses.

Abstract: Methods and systems for providing quality of service over IP networks are disclosed. In one aspect, a flow label field of a header may be divided into first and second portions. The first portion defines a quality of service. The second portion identifies a message flow. Once the first portion defining the quality of service is established by the sending node, no nodes in the transmission path may change the quality of service value. Each node may route packets based on the quality of service field, or may modify the traffic class field of the header based on the quality of service and then route the packet based on the traffic class field. The QoS field can be used to complement a DSCP/traffic class field and provide a better mechanism for end-to-end QoS using IPv6. A service provider can use DSCP within its own administrative domain(s), and end users can set and maintain QoS using the methods described herein, thereby providing a framework for end-to-end QoS using IP packets.
