Method and arrangement in a telecommunications network
First Claim
1. A method for improving reporting of mobility information, implemented in a mobile terminal operating in a wireless communication network, wherein the method comprises:
- detecting a transition for the mobile terminal from an idle state to a connected state; and
transmitting the mobility information to a base station in the wireless communication network, in response to or in connection with the detected transition, wherein the transmitted mobility information includes an estimate of a speed for the mobile terminal or information that can be used to estimate a speed for the mobile terminal when the mobile terminal is nonstationary,wherein transmitting the mobility information to the base station comprises including at least some of the mobility information in a message sent as part of a Radio Resource Control reconfiguration procedure.

Abstract
Methods and apparatus for improving the reporting of mobility information are disclosed. An example method, suitable for implementation in a mobile terminal such as an LTE UE, begins with the detecting of a transition from idle state to connected state. The mobile terminal subsequently transmits mobility information to the network in response to or in connection with the transition. The mobility information sent to the network includes one or more of several information elements or information types, including a list of recently visited cells, including information specifying a time-of-stay in each cell, or timestamp information that can be used to derive the mobile terminal'"'"'s time in each cell. GPS-based speed information or other generic speed information may be included. Complementary methods for implementation in a base station and corresponding apparatus are also disclosed.
