Abstract: A group division method based on a social relationship in combination with a selfish preference order is provided, the method includes the following steps: step 1, forming a preliminary group by simulating choices of users to gather into groups for sharing cost based on social values of the users; and step 2, drawing up combining and splitting rules according to a selfish preference order, subjecting the groups obtained in step 1 to combining or splitting on a basis of the combining and splitting rules, and ending the combining or splitting upon reaching a Nash equilibrium point, thereby obtaining stable groups. In the scenario of a static game with complete information, a Nash equilibrium point is found out based on the combination of a social relationship and a selfish preference order, so that the stability of group division is improved, and extreme users are removed.

Abstract: Embodiments of the present disclosure relate to a method and an apparatus for probing a fronthaul topology. The method includes: sending, by a baseband device, a source route probe frame; receiving a destination route probe frame, where the destination route probe frame is formed after a first transport network device records first port information in the source route probe frame and a second transport network device records second port information in the source route probe frame; and determining, by the baseband device, probe information according to the destination route probe frame, and sending the probe information to an element management system EMS.
