摘要： A scenario may arise in which a circuit switched (CS) bearer reservation is successful but a voice media switching from packet switched (PS) to CS performed by a mobile switching center (MSC) server fails. Certain embodiments provides systems, apparatuses, and methods for recovery from such a scenario. A method, for example, can include determining whether session transfer of a user equipment is possible in response to a request from a network element to initiate session transfer of the user equipment and reporting to the requesting network element either a generic or specific indication that the transfer is not possible, when it is determined that the session transfer is not possible.

摘要： There are provided measures for an enhanced data access technique for user data. Such measures exemplarily comprise detection of unfeasibility of a data access of data of a specified user at a home subscriber server using a mobile subscriber telephone number due to ambiguity of the mobile subscriber telephone number as a user identity and unavailability of an international mobile subscriber identity as a private identity of the specified user, and selection of a process for enabling the data access of data of the specified user at the home subscriber server using the mobile subscriber telephone number on the basis of a necessity of the international mobile subscriber identity as a private identity for the data access of data of the specified user.
摘要翻译：为用户数据提供了增强的数据访问技术的措施。这样的措施示例性地包括由于移动用户电话号码作为用户身份的不确定性和国际移动用户身份的不可用性，使用移动用户电话号码检测在家庭订户服务器处的指定用户的数据的数据访问的不可行性指定用户的私有身份，以及基于国际移动用户身份作为私人的必要性，使用移动用户电话号码选择用于在归属订户服务器处启用数据访问指定用户的数据的过程用于指定用户的数据访问的身份。
