This application discloses a communications method and apparatus. An example method includes: receiving, by a RAN node, a first message from an AMF node, where the first message includes specified area related information of a terminal device, and the specified area related information is used to indicate a specified area of the terminal device; and when the RAN node determines, based on the specified area related information and first location information of the terminal device, that the terminal device moves out of the specified area, sending, by the RAN node, the first location information or first indication information to the AMF node or an SMF node, where the first indication information is used to indicate that the terminal device already moves out of the specified area.

Systems may establish a Session Initiated Protocol (SIP) session during a Home Subscriber Server (HSS) outage. The systems may include Network Functions (NF) that perform steps for establishing the SIP session and/or bypassing the HSS experiencing the outage. For instance, an Interrogating (I)-Call Session Control Function (CSCF) may modify a terminating message received from a User Equipment (UE) to generate a modified terminating message, and send one or more instances (e.g., forks) of the modified terminating message to one or more candidate Serving (S)-CSCFs. A particular S-CSCF of the candidate S-CSCFs may comprise the registered S-CSCF and may respond to an instance of the modified terminating message. In some embodiments, the I-CSCF may establish the SIP session by sending an instance of the modified terminating message to a designated S-CSCF. The designated S-CSCF may determine which candidate S-CSCF comprises the registered S-CSCF, for instance, by querying the candidate S-CSCFs.

Methods, systems, and devices are described for wireless communication. A wireless device such as an in-vehicle system (IVS) may transmit an emergency call (eCall) message to a third party eCall server using a communication session which may be packet based or circuit based. The eCall message may include session information and telematics data. The third party eCall server may relay the session information and telematics data to a public safety answering point (PSAP). For example, the third party eCall server may generate an automatic text-to-speech message that is transmitted to the PSAP over a public communications network. In some cases, the third party eCall server may transmit a response to the wireless device including metadata based on the telematics data transmitted in the eCall message. The eCall message may also include a call-back number, and the PSAP may contact the wireless device directly using the call-back number.

A handheld video game controller is operable in Bluetooth Low Energy (BLE) mode to allow for sending controller input data to a target BLE device in a manner that bypasses any operating system (OS) restrictions that might otherwise be imposed on game controller input. When operating in the BLE mode, the handheld video game controller pairs (establishes a radio link) with a BLE device executing a client application used for video game streaming. During gameplay, the video game executes on a host computer and the player provides user input to the game controller to control an aspect of the video game. In response to such user input, the game controller sends controller input data to the BLE device via a radio of the game controller. The player may switch between operating the game controller in BLE mode and receiver mode using input gestures on the game controller.

This application provides a communication method and a related apparatus. The method includes: receiving a first signal on a first frequency domain resource and a first time unit, where the first signal is a primary synchronization signal or a secondary synchronization signal, the first signal includes at least two signals, a second signal in the at least two signals in the first signal is mapped to a second frequency domain resource, a third signal in the at least two signals is mapped to a third frequency domain resource, and the second frequency domain resource and the third frequency domain resource are located in the first frequency domain resource; and performing signal detection on the first time unit based on at least one of the at least two signals.

The delivery of streaming content to User Equipment (UE) connected to a wireless communication network supports a decision between unicast and broadcast/multicast delivery systems to be made using information associated with the RN(s) serving the UEs. In serving areas associated with a limited number of UEs, the streaming content can be delivered using a series of unicast transmissions, while in other areas where there are a sufficient number of UEs receiving the same content, a broadcast/multicast delivery service can be employed. The RN can switch between the unicast and broadcast/multicast delivery services based on changing demands and situations.

A method of establishing communication links during a failure within a mobile communications network includes detecting disruptions in communications between a plurality of base stations and a plurality of mobile terminals. Survivability components are activated within the base station and the mobile terminal to operate in a survivability mode. The survivability mode enables communications and services to be provided by the surviving base stations to mobile terminals through activated survivability components. The alternate communication links may operate for as long as a disruption exists.

Methods and nodes for coordinating communication sessions are described herein. A method includes providing, by a control system, a signaling anchor point at a domain transfer function in a visited multimedia subsystem for an access signaling leg and a remote access signaling leg for a communication session between a user element and a public service access point and coordinating call signaling for the communication session via the access signaling leg and the remote signaling leg.

Aspects of the disclosure relate to routing of an emergency communication under fault conditions. Routing can be implemented in a packet-switching (PS) network that provides voice service. For a network node of the PS network, availability to route the emergency communication through a specific emergency service routing number (ESRN) can be determined and, in response to the network node being unavailable, administrative data associated with the ESRN can be accessed. In addition, an identifier associated with the administrative data can be updated (e.g., created or modified) with data indicative of the device that originated the emergency communication. The administrative data and the resulting identifier can be delivered to a second network node that can route the emergency communication to an emergency service network.
