A mobile communications system includes switching between communication paths based on the quality of service. A VoIP service is coupled to a mobile network and a wireless local-area network (WLAN) via a wide-area IP network. A plurality of mobile communications devices are associated with VoIP telephone numbers. A public switched telephone network (PSTN) is coupled to the plurality of mobile communications devices and coupled to the VoIP service. A quality of service server is coupled to the plurality of mobile communications devices via the wide-area IP network for determining the quality of data channels to a mobile communications device via the mobile network and to the mobile communications device via the WLAN. A voice call is carried over one of the mobile network, the WLAN, and the PSTN depending on the quality of the data channels.

Mobile equipment including a geo-localization device arranged to determine a current position for the mobile equipment in a space to be mapped; a communication device arranged to communicate with access points of a local network implemented in the space to be mapped; a control component arranged: to control each access point selectively and in independent manner via the communication device so as to cause said access point to transmit a reference signal; to use the reference signals received by the communication device to evaluate respective qualities for the connections between each of the access points and the mobile equipment in the current position.

A method for discovering devices in a mesh network. After receiving a plurality of request frames sent by a large number of first devices, a second device sends a response frame via broadcast form times, at an interval of n; and each first device that receives the response frame establishes a mutual discovery relationship with the second device. In the event that an extremely large number of devices are present in the mesh network, the present invention may greatly improve the probability of discovery between devices, and effectively suppress network storming, thereby enabling the mesh network to maintain a good network performance.

Embodiments of a non-access point (non-AP) EHT station (EHT STA) configured to operate as part of an STA multi-link logical entity (STA MLLE) comprising the EHT STA and one or more other non-AP EHT STAs are generally described herein. The STA MLLE is configured to be associated with an access point (AP) MLLE (AP MLLE) comprising a plurality of EHT APs. The EHT STA is configured to decode a beacon frame received from the EHT APs of the AP MLLE including a multi-link beacon check element to indicate which of the one or more multiple links has a critical update to its link parameters. When the multi-link beacon check element indicates an update to link parameters for the link between the EHT STA and its associated EHT AP, the EHT STA is to configured obtain the updated link parameters either waking-up at a target beacon transmission time (TBTT) or send a probe request.

A network access method includes transmitting a request for acquiring shared network information to a shared server if a mobile communication terminal detects that a network identification of a PLMN of a visited place does not exist in a local memory of the mobile communication terminal; receiving the shared network information which the shared server transmits in response to the request, and acquiring the network identification of the PLMN of the visited place from the shared network information; adding the network identification of the PLMN of the visited place to an EPLMN list by the mobile communication terminal; and accessing a network according to the EPLMN list.

Embodiments of the present disclosure provide a device to device (D2D) communication method and apparatus, to resolve at least a problem of a low success rate of discovery between user equipments in the prior art. The method includes: determining, by a first user equipment (UE), first signaling to be sent, where the first signaling includes one or a combination of the following information: a transmission probability, a quantity of retransmission times, a transmission period, a type of a cyclic prefix (CP), a transmit power, a current quantity of hops, a quantity of antenna ports, a transmission mode, a bandwidth of a D2D link, a D2D link frame number, time division duplexing (TDD) uplink and downlink configuration information, or information indicating whether the first UE is within a network; and sending, by the first UE, the first signaling to second UE using the D2D link.

Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a mobile device may receive configuration information, associated with configuring a state of the mobile device, via a unicast transmission, and may access a header-compressed broadcast transmission using the configuration information received via the unicast transmission. In some aspects, a network entity may transmit configuration information, to facilitate decompression of a header-compressed broadcast transmission, via a unicast transmission to a mobile device of a plurality of mobile devices, and may transmit the header-compressed broadcast transmission to the plurality of mobile devices in accordance with the configuration information.
