    Abstract: 本公开提供了一种编码格式确定方法及装置,涉及通信技术领域,所述方法包括:在VoLTE通话时,接收呼叫中心转发的数据包,数据包携带有第一编码格式;检测第一编码格式与协商的第二编码格式是否相同;若不相同,则将通话过程中所使用的编码格式由第二编码格式修改为第一编码格式;解决了当主叫终端使用其它的编码格式对发送的数据包中携带的数据进行编码时,被叫终端使用协商的编码格式无法对接收到的数据进行解码,导致解码错误和通话过程出现异常的问题;达到了在数据包中携带的第一编码格式与协商的第二编码格式不相同时,使用第一编码格式对接收到的数据包进行解码,保证正常的通话质量的效果。

    Abstract: A network device, capable of understanding communications between an end user and the core network on a RAN network is disclosed. In some embodiments, the device is able to decode the control plane and the user plane. As such, it is able to determine when the end user has requested multimedia content. Once this is known, the device can optimize the delivery of that content in several ways. In one embodiment, the device requests the content from the content server (located in the core network) and transmits this content in a just-in-time manner to the end user. In another embodiment, the device automatically changes the encoding and resolution of the content, based on overall monitored network traffic. In another embodiment, the device automatically selects or modifies the format and resolution options based on overall bandwidth limitations, independent of the end user.

    Abstract: Methods and systems are provided for filtering packets in a wireless communication system in the to-mobile subscriber direction. This filtering is at least in part based on RF circuit state information. For example, a packet filter is used that either permits or denies packets from reaching a mobile subscriber based on whether there is already an established RF circuit to provide packets to the mobile subscriber. Alternatively, or in addition, the packet filter may consider the history of circuit state transitions associated with a particular mobile subscriber, the percentage (or aggregate number) of available airlink resources that are currently in use, and/or the length of time associated with the dormancy of a mobile subscriber's RF connection. In various embodiments, the packet filter may cause one or more packets to be sent to a mobile subscriber using a special data channel that does not require the establishment of an RF circuit.

    Abstract: A scheme for managing conflict resolution in an ABR streaming environment with respect to a bandwidth pipe serving a customer premises, in one aspect when a session request is received from a new ABR client launched in the customer premises that includes one or more existing ABR clients having corresponding streaming sessions, a bandwidth forecasting module is configured to forecast bandwidth, requirements with respect to the corresponding ABR streaming sessions after accounting for a bandwidth requirement for the new ABR client's session request, A conflict condition may be detected if any of forecasted band width requirements violates a bitrate threshold policy relative to the corresponding ABR streaming sessions and/or the new session being requested, if there is a conflict, an interactive session may be launched with one or more clients for facilitating user selection of one or more options relative to the impending conflict condition.

    Abstract: An existing path (20) in a connection-oriented network (5) requires resizing from a first size to a second size. Nodes exchange control plane signalling (30) with other nodes which advertises available resources on links between nodes. A node on the existing path (20) receives (202) a request to establish a path capable of being resized to the second size. The node determines (203), using information acquired by the control plane signalling (30) with other nodes, a new path between nodes capable of supporting the second size. The node signals (204) to establish the new path and switches (205) traffic from the existing path to the new path. The node causes the new path to be resized to the second size. Nodes exchange control plane signalling (30) with other nodes which advertises whether a link supports resizing, such as OSPF-TE advertisements.

    Abstract: A base station in an OFDMA system which determines a modulation and coding scheme to use for a packet of a certain size to be transmitted by a Mobile Station. The base station schedules transmissions by mobile stations and transmits packets. The base station includes a processing unit which determines a number of time-frequency resources required to transmit the packet for a modulation and coding scheme, determines an SlNR based on the number of time-frequency resources used and available power at the mobile station, determines a transmission rate as a ratio of the packet size transmitted to the number of time-frequency resources used, sets a rate to zero if the determined SlNR is lower than a threshold SINR required for the modulation and coding scheme, and selects the modulation and coding scheme with a highest transmission rate. The base station includes a memory storing modulation and coding schemes.
