Abstract:
A method for establishing data connections on a mobile network, a mobile network, and a policy control entity are disclosed. The method includes: establishing a data channel between a user equipment (UE) and a gateway (GW), and allocating an Internet Protocol (IP) address to the UE according to an address allocation request or a data channel setup request sent from the UE; and triggering the policy control entity to establish or update a policy control session according to the IP address. By using the mobile network and the policy control entity under the present disclosure, after the data channel is established between the UE and the GW, the GW may trigger the policy control entity to establish or update a policy control session.
Abstract:
A policy decision function (PDF) addressing method includes: receiving a PDF allocation request that contains a user equipment (UE) identifier (ID) from a second network element (NE); obtaining ID information of a PDF associated with the UE ID according to pre-registered addressing information of the PDF, where the addressing information of the PDF is an association between the UE ID and the ID information of the PDF, and the PDF associated with the UE ID is accessed by a first NE; and sending the obtained ID information of the PDF to the second NE.

Abstract:
The embodiments of the present invention provide a processing method and processing system for instant messages in a network conference. The processing method for instant messages comprises: establishing connection between a conference application server and an instant message server, wherein the conference application server is further connected to a conference client, and the instant message server is further connected to an instant message client; and controlling message transfer between the conference application server and the conference client or between the instant message server and the instant message client according to the state of the conference client and the state of the instant message client. With the manners above, the processing method and processing system of the present invention enable a message client to which the conference client in the network conference corresponds to receive instant messages in a more humanized manner, thereby improving the experiences of the user.
Abstract:
A session management method and an apparatus are provided, so that a terminal device accesses a 4G network by using a 5G technology, to support native access of a 5G terminal device. The method includes: A mobility management device receives a mobility management message sent by a terminal device, where the mobility management message includes an N1 container, the N1 container includes a session management message, and the session management message is used to establish, update, or delete a packet data unit PDU session of the terminal device; the mobility management device changes the session management message into a bearer processing message, where the bearer processing message is used to establish, update, or delete a bearer of the terminal device; and the mobility management device sends the bearer processing message to a serving gateway.
Abstract:
Embodiments of this application provide a connection re-establishment method, a device, and a system, to re-establish a connection of a terminal to a specified network device. The connection re-establishment method includes a source network device that determines that a connection of a terminal is to be released. The source network device obtains information about a target network device, and the source network device sends the information about the target network device, where the information about the target network device is used to re-establish the connection to the target network device.
Abstract:
A method for data reconstruction includes: obtaining a data migration list, where the data migration list indicates a partition with data to be migrated on a storage node with data to be migrated; generating a data migration task according to the data migration list and routing table information, where the routing table information indicates correspondence between a storage node in a cluster and a partition; and concurrently executing data migration tasks of a storage node in the cluster to reconstruct data. In addition, a device for data reconstruction and a storage system are further provided accordingly.
Abstract:
Embodiments of the present invention relate to communications technologies and disclose a tunnel management method, a tunnel management apparatus, and a communications system so that a node that causes failure of a tunnel management request can be determined According to the present invention, a response returned by a tunnel management node to an initiating node includes not only a cause value of tunnel management request failure but also information of the node that causes failure of the tunnel management request, so that the initiating node can find the node that causes failure of the tunnel management request and determine the error checking direction. The present invention is applicable to network devices in a communications network.
Abstract:
A method, a device, and a system for controlling tunnel identifier allocation are provided. The method includes: determining whether a type of a current procedure allows a Serving Gateway (SGW) to change a Tunnel Endpoint Identifier (TEID) and/or an Internet Protocol (IP) address (S110); and sending a modify bearer request message to the SGW, in which the modify bearer request message is used for notifying the SGW of whether the SGW is allowed to change the TEID and/or the IP address (S120). The loss of service data packets of a user or the service interruption caused by that the SGW modifies the TEID and/or the IP address is avoided.
Abstract:
The present disclosure provides an error indication processing method and system, and a device, and relates to the field of communications technologies, to resolve a problem that normal transmission of a service data packet is affected due to an inconsistency between contexts of an access node and a user plane network element in a next generation mobile communications network.
