Abstract: A method for detecting a message loop, a routing agent apparatus, and a networking system. The method for detecting a message loop includes: receiving a request message sent by a network element apparatus; acquiring routing information for sending the request message to a server apparatus; detecting whether a next-hop link for sending the request message in the routing information and a link for receiving the request message belong to a same link set; and sending a response to the network element apparatus that a message loop is detected, when it is detected that the link for sending the request message in the routing information and the link for receiving the request message belong to a same link set. The technical solutions disclosed herein can improve the efficiency of detecting the message loop and thus have strong practicability.

Abstract: A communication method and apparatus are provided, so that an access network device can configure an initial hyper frame number (HFN) and a reference sequence number (SN) for a terminal device in time when no data packet is received from a core network device. The method includes: A first core network device obtains an initial multicast/broadcast service (MBS) quality of service flow identifier (QFI) SN corresponding to a first MBS session, and sends the initial MBS QFI SN in a first procedure. The first procedure is a procedure before a the 1st data packet of the first MBS session is sent to an access network device. After receiving the initial MBS QFI SN in the first procedure, the access network device may determine an initial HFN and a reference SN based on the initial MBS QFI SN, and send the initial HFN and the reference SN to a terminal device.

Abstract: A terminal device determines whether an available first resource is present, where the available first resource is associated with a hybrid automatic repeat request (HARQ) process configured with a HARQ mode A, and the HARQ mode A supports retransmission. When the available first resource is present, the terminal device sends a timing advance report to a network device by using the available first resource.
