摘要： A method and apparatus for interworking between push-to-talk over cellular (PoC) systems and instant messagaing (IM) systems is provided. An interworking entity that behaves like a PoC client to a PoC server and as an IM client to the IM server is provided. The interworking entity may be implemented as part of the PoC server or the IM server. The interworking entity listens to talk bursts from the PoC server and when it receives a talk burst the interworking entity sends the message to the IM client via the IM server. In an embodiment, the interworking entity listens to talk bursts or audio clips from the IM server and when it receives them, stores them in a temporary storage memory and converts them to a streaming format. The interworking entity then requests the floor from the PoC server, and, once the floor is granted, streams the stored audio clip or talk burst to the PoC server. The PoC server then distributes the clips to the PoC clients.

摘要： A method and apparatus estimate an offset between a carrier frequency of a transmitter and a local reference frequency of a receiver. A received signal is separated into frequency synchronization signals and data, and a determination is made whether the frequency synchronization signals are adequate for estimating the frequency offset. This determination may be made based on, e.g., an estimated Doppler spread, an estimated signal to noise ratio, and/or an available amount of frequency offset estimation time. The frequency offset is estimated based on the determination results. If the frequency synchronization signals are adequate for estimating the frequency offset, the frequency synchronization signals are used for determining the frequency offset. Otherwise, the rate of the frequency synchronization signals is increased, e.g., by using the data as frequency synchronization signals, in which case the data is combined with the frequency synchronization signals to determine the frequency offset.
摘要翻译：方法和装置估计发射机的载波频率和接收机的本地参考频率之间的偏移。将接收到的信号分离成频率同步信号和数据，并且确定频率同步信号是否足以估计频率偏移。可以基于例如估计的多普勒扩展，估计的信噪比和/或可用的频率偏移估计时间量来进行该确定。基于确定结果估计频率偏移。如果频率同步信号足以估计频率偏移，则使用频率同步信号来确定频率偏移。否则，例如通过使用数据作为频率同步信号来增加频率同步信号的速率，在这种情况下，数据与频率同步信号组合以确定频率偏移。

摘要： Apparatuses, methods, and systems are disclosed for determining what type of network connection to establish from an operating system (“OS”) specific connection capability. One apparatus includes a processor and a transceiver that communicates with a mobile communication network over one or more access networks. The processor receives a first request to establish a network connection. Here, the first request includes a first connection capability, the first connection capability being an OS-specific parameter indicating a preferred connection characteristic. The processor selects a routing policy rule based on the first connection capability and sends (via the transceiver) a second request to the mobile communication network to establish a first type of network connection. Here, the first type of network connection is indicated by the selected routing policy rule.

摘要： Apparatuses, methods, and systems are disclosed for disabling a pending NSSAI. One method includes receiving, from a lower layer, a first indication of a radio link failure event, wherein the radio link failure event occurs during an authentication procedure of a network slice, and wherein the radio link failure event corresponds to unavailable cell coverage and disabling a pending NS SAI associated with network slice based at least in part on the radio link failure event. The method includes receiving, from the lower layer and after disabling the pending NSSAI, a second indication indicating available cell coverage and transmitting a registration request for the network slice in response to the available cell coverage, wherein the registration request comprises a requested NSSAI, and wherein the request NSSAI comprises a S-NSSAI associated with the pending NSSAI.

摘要： Apparatuses, methods, and systems are disclosed for Digital Identifier-based subscription onboarding. One apparatus includes a memory coupled to a processor, the memory storing instructions executable by the processor to control the apparatus to acquire a Digital Identifier (“DIG-ID”) comprising a verifiably secure identity, and to generate a digital signature of the DIG-ID and a timestamp using a private key. The instructions are executable by the processor to control the apparatus to send a first request to a mobile communication network and to receive a response containing an onboarding authentication success indication and a verified DIG-ID, the first request including the DIG-ID, the timestamp and the digital signature. The instructions are executable by the processor to establish a provisioning connection to the mobile communication network and to receive a subscription credential and/or a user subscription profile via the provisioning connection.
