AI Technical Summary

Problems solved by technology

[0037] Regarding fragmentation: besides retransmissions, fragmentation of packets will also cause delays in packet arrival, and thus affect interval timing
[0038] Although reliable interval timing in a network with a fairly predictable air interface is a challenge, a system near its full capacity with degraded radio conditions is critical to Detecting talk / silent period status of UE is even more of a challenge

Embodiment Construction

[0110] figure 1 is a block diagram illustrating an embodiment of the system.

[0111] figure 1 A single base station (BS) 102 comprised by the telecommunications network system 100 is shown. The telecommunications network system 100 also includes a network 100A, which includes an access network (AN) and a core network (CN).

[0112] The BS 102 is linked to a control node comprised by the network 100A, which may be (as an example) a base station controller (BSC) or a radio network controller (RNC).

[0113] Although a single BS 102 is depicted, common telecommunications network systems 100 deploy multiple BSs that are typically identical to BS 102 .

[0114] The BS 102 has a schematically shown service or coverage area 103 in which a first device or User Equipment (UE) 101 is served. The UE 101 communicates via the link 104 via the BS 102 to a receiving end included in the access / core network 100A.

[0115] The BS 102 is connected to the access / core network 100A via a link...

Abstract

Methods, systems and devices for detecting a silent period state 200A in a first device 101 . The detection is performed by a second device 102 in communication with the first device, receiving the first device's transmission. The silent period state corresponds to a state in which the first device has no speech samples to send to the second apparatus. The second device receives 413 the transmission from the first device and determines 414A, 414B, 414C the type of transmission received. The second device counts 415 the number of received transmissions of the first type and times the time interval between the last received transmission of the first type and the last received transmission of the second determined type. Upon receiving a transmission of the first type, the second device utilizes a logical expression according to the threshold-based count number of transmissions of the first type and the last received transmission of the first type with the last received transmission of the second type The time interval between the transmissions is evaluated 416 to detect 416 whether the first device is in the silent period state 420 .

Description

technical field [0001] The present invention generally relates to methods, systems and devices enabling detection of silent period status in user equipment operating in an alternate talk-silent state. Background technique [0002] In a typical cellular network (also referred to as a wireless communication system), user equipment (UE) communicates with one or more core networks (CN) via a radio access network (RAN). [0003] A UE is a mobile terminal through which a subscriber can access services provided by the operator's core network. A UE may, for example, be a communication device with wireless capabilities, such as a mobile phone, cellular phone, laptop computer or tablet computer (sometimes referred to as a surfboard). A user UE may be a portable, pocketable, hand-held, computer contained, or vehicle-mounted mobile device capable of communicating voice and / or data via a radio access network with another entity (e.g., another mobile station or server) . [0004] A UE ...
