Abstract: The present invention discloses a congestion control method and apparatus. A priority of a DCN type supported by a core network is defined. When a DCN node is congested, congestion control may be first performed on a DCN type having a low priority. Therefore, access by UE of the DCN type having a low priority is prevented, and normal access by UE of a DCN type having a high priority can be ensured. In addition, it can be avoided that the DCN node monitors a load status of each supported DCN type, thereby reducing policy complexity of the DCN node. Furthermore, it is avoided that the DCN node is not congested but a particular type of DCN is congested, thereby improving resource usage.

Abstract: The present application discloses a DCN processing method for a PLMN that is applied to a network sharing scenario. An access feedback message of a network side is received, and selection assistance information of a DCN and an identifier of a PLMN that serves UE are obtained from the access feedback message, so as to know a PLMN that is actually accessed by the UE. A correspondence between the selection assistance information of the DCN and the identifier of the PLMN that serves the UE is stored. When the UE moves to coverage of the PLMN, a requested DCN to be accessed can be directly determined according to the correspondence, and a RAN node is requested to access the determined DCN. Therefore, a redirection process is reduced, and resource overheads are reduced.

Abstract: Embodiments of the present disclosure provide an RTP packet transmission method and apparatus. A GCS AS or a BM-SC provides synchronization source information of the GCS AS and synchronization source information of the BM-SC for UE, so that the UE can continuously receive RTP packets. On one hand, the GCS AS (or the BM-SC) may provide the synchronization source information of the GCS AS (or the synchronization source information of the BM-SC) for the UE by sending an RTP packet. On the other hand, the GCS AS (or the BM-SC) further provides the synchronization source information of the BM-SC (or the synchronization source information of the GCS AS) for the UE. Therefore, when being in a unicast (multicast) transmission mode, the UE can obtain both of the synchronization source information of the GCS AS and the synchronization source information of the BM-SC.

Abstract: Embodiments of this application provide a method and an apparatus for determining a user equipment route selection policy. The method may include: A first policy control network element obtains first information, where the first information is used to determine a first user equipment route selection policy. The first policy control network element sends the first user equipment route selection policy to first user equipment, where the first policy control network element belongs to a visited network of the first user equipment. According to this application, user equipment roams to a visited network, and a user equipment route selection policy may be determined by the first policy control network element based on the first information, so that the visited network may provide the user equipment route selection policy for the user equipment, to implement a route selection service of the user equipment in a roaming scenario.
