摘要： The invention relates to a method for establishing a push-to-talk-(Ptt) communication link between two Ptt devices (1,2), in which the data of different types, such as voice data (Sp), audio data (A), video data (V) etc., is transmitted between the Ptt devices (1,2). The first Ptt device (I) transmits a Ptt link request, and subsequently a communication link is established for at least one selection of said different types of data via a communication channel (F1, NF) according to a communication protocol. According to the invention, the Ptt link request contains priority information which enables the data types to be allocated a transmission priority, and the communication protocol only authorises the communication channel (F1, NF) to be established if the second Ptt-device (2) is available for the data type or for the data types having the highest transmission priority. The transmission of one data type, which has a lower transmission priority, by means of said communication channel (FI, NF) is only authorised if the second Ptt-device (2) is available for said data type, and the second Ptt-device (2) is also available for all data types with a higher transmission priority.
摘要翻译：本发明涉及一种用于在两个Ptt设备（1,2）之间建立一键通（Ptt）通信链路的方法，其中不同类型的数据，例如语音数据（Sp），音频数据（A）），视频数据（V）等在Ptt设备（1,2）之间传输。第一Ptt设备（I）发送Ptt链路请求，随后根据通信协议经由通信信道（F1，NF）为至少一个选择所述不同类型的数据建立通信链路。根据本发明，Ptt链路请求包含优先级信息，使得数据类型能够被分配传输优先级，并且通信协议仅授权通信信道（F1，NF）被建立，如果第二Ptt设备（2）可用于数据类型或具有最高传输优先级的数据类型。如果第二Ptt设备（2）可用于所述数据类型，则仅通过所述通信信道（FI，NF）传输具有较低传输优先级的一种数据类型，并且第二Ptt设备（2）也可用于具有较高传输优先级的所有数据类型。

摘要： During a registration procedure by a User Equipment (UE) via a Proxy Call Session Control Function (P-CSCF) node and a Serving Call Session Control Function (S-CSCF) node, the S-CSCF node provides a policy indicator in a response message to a register request message. The policy indicator enables subsequent operation of the node to be controlled according to whether or not a registered UE has an associated policy. As such, delays (such as delays associated with retrieving an associated policy) are only experienced by UEs that have previously been determined as having such an associated policy, rather than all UEs being affected in the same way.
摘要翻译：在由用户设备（UE）经由代理呼叫会话控制功能（P-CSCF）节点和服务呼叫会话控制功能（S-CSCF）节点的注册过程中，S-CSCF节点在响应中提供策略指示符消息发送到注册请求消息。策略指示器使得能够根据注册的UE是否具有相关联的策略来控制节点的后续操作。因此，延迟（例如与检索相关联的策略相关联的延迟）仅由先前已被确定为具有这样的关联策略的UE经历，而不是以相同的方式影响所有UE。

摘要： Techniques for managing multiple ICS sessions in an IMS network are described. In one method, a MSC server detects that a user terminal has been transferred from a first access network to a second access network and, in response, sends a message to an SCC AS, the message indicating transfer of the user terminal. The MSC server receives, in response, one or more requests for MSC server-assisted mid-call feature services for the user terminal, and assigns transaction identifiers to one or more sessions held for the user terminal or to one or more conference participants corresponding to the user terminal. Corresponding techniques carried out at an SCC AS are also described.
摘要翻译：描述了在IMS网络中管理多个ICS会话的技术。在一种方法中，MSC服务器检测到用户终端已经从第一接入网络传送到第二接入网络，并且作为响应，向SCC AS发送指示用户终端的传送的消息。 MSC服务器响应地接收用于用户终端的对MSC服务器辅助中间呼叫特征服务的一个或多个请求，并且将事务标识符分配给为用户终端保持的一个或多个会话或者与一个或多个对应于用户终端。还描述了在SCC AS处执行的相应技术。

摘要： A method of enabling the management of handovers of voice calls from a Packet Switched, PS, access to a Circuit Switched, CS, access where the voice calls are established using an IP Multimedia Subsystem, IMS, network. The method comprises performing a first IMS registration of a user via said PS access including setting for the user in a Home Subscriber Server, HSS, of the user's home network, an identifier of a first access transfer control function, which access transfer control function is responsible for anchoring user media sessions in an access transfer gateway of a serving network, and notifying a mobility function within said service network of the set identifier. A second or further IMS registration of the same user is then performed via said PS access, it being determined that said first IMS registration exists. As a consequence, the setting of an identifier of a second or further access transfer control function in the HSS for the user is prevented, while either the setting of the identifier of the first access transfer control function is maintained, or is replaced with an identifier of a service centralization and continuity application server. The mobility function is notified of any change to the set identifier. In the event of a requirement to handover an ongoing voice call associated with said second or further IMS registration from said PS to said CS access, the identifier currently set in the HSS and identified to the mobility function is used to manage the handover.

摘要： A first communications device communicates with a second communications device by means of a communications network. The first communications device receives information from the communications network, wherein the information comprises a network load value and a mean delay time value. The first communications device ascertains whether the network load value satisfies a predetermined relationship with respect to a threshold load value and if the predetermined relationship is satisfied then it communicates a data packet over the network at a designated time that is ascertained by ascertaining one of a number of different wait time values, wherein the ascertained wait time value has a mathematical expectation equal to the mean delay time value. The first communication device then waits an amount of time corresponding to the ascertained wait time, without attempting to communicate the data packet over the communications network during the time in which the first communications device is waiting.
