13 results about "Service Access Point" patented technology

A Service Access Point (SAP) is an identifying label for network endpoints used in Open Systems Interconnection (OSI) networking. The SAP is a conceptual location at which one OSI layer can request the services of another OSI layer. As an example, PD-SAP or PLME-SAP in IEEE 802.15.4 can be mentioned, where the Media Access Control (MAC) layer requests certain services from the Physical Layer. Service access points are also used in IEEE 802.2 Logical Link Control in Ethernet and similar Data Link Layer protocols.

Split multi-link system

Embodiments of the present disclosure relate to a split multi-link system. Systems and methods are provided for defining a split multi-link system. For example, a split multi-link system can define a multi-link device (MLD), where the MLD operates a first radio from a first AP and a second radio from a second AP of a plurality of APs through a media access control (MAC) service access point (SAP) of the split multi-link system. The first radio from the first AP and the second radio from the second AP can operate at different frequencies. The split multi-link system can also associate the first radio from the first AP and the second radio from the second AP with the MLD, where, using the MLD, the split multi-link system can transmit or receive one or more data frames from the MLD to a non-MLD or MLD client device using the first radio or the second radio.

A User-Centric Decellular Latency Analysis Method Considering Queuing

This invention relates to the field of wireless communication technology, and more particularly to a user-centric decellularized network latency analysis method considering queuing. The method includes: constructing an uplink transmission system and signal model; employing maximum ratio combining (MRC) reception at access points; establishing a multi-access point cooperative reception model based on the user's corresponding service access point set; representing the service rate of the user queue as a function of the steady-state transmission success probability, and deriving the steady-state transmission success probability coupled with the state of interfering user queues; determining the fully unsaturated region that keeps the network in a stable state; calculating the average latency of user data packets, and determining the optimal transmission probability that minimizes the user's average latency based on the relationship between average latency and transmission probability. This method achieves a joint characterization of the transmission and queuing processes in user-centric decellularized networks, improving the accuracy and applicability of user latency analysis, and providing a basis for the design and optimization of latency-sensitive decellularized networks.

Fast basic service set transition for multi-link operation

This disclosure provides methods, devices and systems that facilitate mobility of wireless communication devices configured for multi-link operation (MLO). Particular aspects more specifically relate to facilitating fast basic service set (BSS) transitions by wireless communication devices that support MLO. For example, some aspects provide support for station (STA) multi-link device (MLD) roaming between access point (AP) MLDs, from an AP MLD to a non-MLO AP, or from a non-MLO AP to an AP MLD. In some aspects, a STA MLD may be configured to use a medium access control (MAC) service access point address (MAC-SAP address) of the AP MLD when re-associating or communicating with a legacy AP or with an AP MLD. In such aspects, the MAC-SAP address may be used by all STAs of the non-AP MLD for fast BSS transitions.

Mapping a contact center service request to a modality

ActiveUS12603956B2Special service for subscribersTelephone data service arrangmentsPhysical medicine and rehabilitationUser device
A universal contact center service access point is mapped to a service access point specific to a determined modality to establish a connection between a user device and a contact center operator device and associated with that modality. A request for a contact center engagement is obtained from a user device, in which the request includes a universal contact center service access point. Responsive to the request, the universal contact center service access point is mapped, based on a record associating multiple modalities with the universal contact center service access point, to a service access point specific to one of those multiple modalities determined based on information associated with the user device. The contact center engagement is then facilitated over a connection, established based on the mapping, between the user device and a contact center operator device associated with the service access point.

Seamless roaming for multi-link device clients

Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.
