The method includes: receiving, by an SCEF, a first request message sent by a third-party server, where the first request message includes an MBMS capability negotiation parameter that is used for video distribution and that is requested by the third-party server; sending, by the SCEF, a second request message to an HSS according to the first request message, to request the HSS to expose an MBMS capability; sending, by the SCEF, a third request message to a broadcast multicast service center BM-SC when the SCEF receives a second response message returned by the HSS when the HSS determines to allow the exposure of the MBMS capability, to request to obtain MBMS capability information exposed by the BM-SC; and sending the MBMS capability information obtained from the BM-SC to the third-party server.

Video distribution method and device

This disclosure relates to the technical field, and discloses a network access method, a terminal, an access network, and a core network. The terminal obtains, based on the network service identifier, the network slice type identifier corresponding to a service identifier, and then accesses the network slice based on the access mode corresponding to the network slice type, thereby avoiding unavailability of the service caused by a failure to correctly access the network slice and improving service quality.

Network access method, terminal, access network, and core network

A quality parameter transmission method includes: sending, by the network side device, a first request message to the terminal, where the first request message is used to request a quality parameter related to user experience of a preset service; and after receiving the first request message from the network side device, sending, by the terminal, the quality parameter to the network side device. The network side device obtains, from the terminal, the quality parameter related to user experience of the preset service, and therefore can evaluate network operation quality by using the quality parameter, to facilitate network optimization, provide better network quality for the terminal, and improve user experience.

When a Real-Time Transport Protocol (RTP) packet receiving manner of a user equipment (UE) is switched between a unicast transmission manner and a multicast transmission manner, a group communication service application server (GCS AS) obtains a time difference between a time at which the UE receives a first RTP packet before the switching and a time at which the UE receives a second RTP packet after the switching. The GCS AS calculates a delay difference, according to the time difference, of RTP packet transmissions in different transmission manners, and adjusts, according to the delay difference, timing for RTP packet transmission in the unicast transmission manner.

Method, apparatus and device for multicast and unicast communications of RTP packets

The present disclosure discloses a data transmission method and apparatus. User equipment (UE) measures and transmits a transmission delay to a group communication service application server (GCS AS), or the GCS AS itself determines a transmission delay, so that the GCS AS may determine, according to the transmission delay, a time of sending a packet on a multicast path or a unicast path. Therefore, a problem of out of order of packets or a loss of a packet due to a transmission delay is resolved, and continuity of a communication service is maintained.

Data transmission method and apparatus

A system includes a host processor () and a peripheral device (). The host processor () is coupled to the peripheral device () by a Peripheral Component Interconnect Express (PCIe) compliant link. The peripheral device () can include logic circuitry to identify, based on an application using the device and the host processor (), a read to write ratio utilized by the application; and provide the read to write ratio to the host processor (). The host processor () comprising logic circuitry to send a command signal to a device in communication with the hardware processor across a peripheral component interconnect express (PCIe) compliant link, the command signal indicating a transmission (TX) lane to receive (RX) lane ratio, the TX lane to RX lane ratio corresponding to the read to write ratio identified by the peripheral device (); and receive an indication that the device is capable of supporting asymmetric TX and RX ratios.

Embodiments of the present invention relate to the communications field, and provide a video distribution method and a device. The method includes: receiving, by an SCEF, a first request message sent by a third-party server, where the first request message includes an MBMS capability negotiation parameter for video distribution, the MBMS capability negotiation parameter being requested by the third-party server; sending, by the SCEF, a second request message to an HSS according to the first request message, to request the HSS to expose an MBMS capability; sending, by the SCEF, a third request message to a broadcast multicast service center BM-SC after the SCEF receives a second response message returned by the HSS when the HSS determines to allow the exposure of the MBMS capability, to request to obtain MBMS capability information exposed by the BM-SC; and sending the MBMS capability information obtained from the BM-SC to the third-party server.

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.
