Abstract: Provided are an address allocation method and apparatus, a core network, a node, a network system and a medium. In at least one of the case of establishing a session, at least two uplink addresses are configured and send to an access network. The access network is a connectivity network formed by a coupling of at least two network element nodes. At least part of the at least two uplink addresses are used for being allocated among the network element nodes. The access network receives the at least two uplink addresses sent by the core network and allocates the at least two uplink addresses. The access network sends at least one downlink address to the core network and determines usage of the uplink addresses. The access network may determine a correspondence between the uplink address and the downlink address. The core network receives the downlink address.

Abstract: Provided are methods and apparatuses for processing indication information. According to a method for processing indication information, a predetermined network element determines a Multimedia Broadcast Multicast Service (MBMS) to be suspended; and the predetermined network element sends, to an Evolved Node B (eNB), indication information used for indicating that the MBMS is to be suspended. The indication information is used for indicating the eNB receiving the indication information to send Multicast Channel (MCH) Scheduling Information (MSI) to User Equipment (UE), and the MSI includes a specific value used for notifying the UE of the MBMS to be suspended. By the technical solution, the problem of how to notify the eNB, how to notify the influenced UEs by the eNB and how to process the suspended service by the UE when the network element selects to suspend the MBMS in the related technology is solved, and effects of timely notifying the eNB and the UE and processing the suspended service by the UE are achieved.
