    摘要： According to certain embodiments, a method in a network node for delivering a time synchronization service comprises obtaining a timing accuracy threshold for a time synchronization service provided to a wireless device; determining, based on a first timing accuracy error at the network node and a second timing accuracy error between the network node and the wireless device, that a timing accuracy of the time synchronization service is equal or superior to the timing accuracy threshold, and transmitting the time synchronization service to the wireless device with a timing accuracy equal or superior to the timing accuracy threshold. The method further comprises, in response to determining that the timing accuracy of the time synchronization service is inferior to the timing accuracy threshold, reconfiguring the network node to improve the timing accuracy of the time synchronization service.

    摘要： Novel techniques of access network selection in multi-access network environment are provided, which allow for avoiding access selection loops for independent access selection processes. The multi-access network environment provides a first access selection function, e.g. a 3GPP access selection function, and a second access selection function, e.g. an ANDSF based access selection function. At least a portion of the first access selection function may be implemented by a network component. At least a portion of the second access selection function may be implemented by a user equipment, e.g. a mobile terminal. According to the proposed concepts, a selection priority information of the first access selection function is made available to the second access selection function.

    摘要翻译： 提供了多接入网络环境中接入网络选择的新技术，可以避免独立接入选择过程的接入选择环路。 多址网络环境提供第一接入选择功能，例如， 3GPP接入选择功能，以及第二接入选择功能，例如， 一种基于ANDSF的访问选择功能。 第一接入选择功能的至少一部分可以由网络组件实现。 第二访问选择功能的至少一部分可以由用户设备实现，例如， 移动终端。 根据所提出的概念，第一访问选择功能的选择优先级信息可用于第二访问选择功能。
