摘要： Methods and corresponding systems in a mobile station for switching communication networks include scheduling an alternate network period during a first communication session between a mobile station and a first network transceiver in a first network, wherein the first network uses a first protocol. During the alternate network period the mobile station searches for a transmission from a second network transceiver in a second network, wherein the second network uses a second protocol. A second communication session is requested between the mobile station and the second network transceiver. A second communication session is initiated between the mobile station and the second network transceiver.

摘要： An MBMS user detection system and methodology (300) is provided for advertising available MBMS services by multiplexing user feedback requests (303) using time, frequency and/or code diversity so that one or more MBMS service users can be detected in a single polling time interval. Available MBMS services are assembled into a user feedback request (302) and assigned unique multiplex signaling codes so that a code for a first MBMS service (302.1) is orthogonal to a code for a second MBMS service (302.k). In addition, a queuing model (610) is provided for analyzing and optimizing how services are advertised in the user feedback requests.

摘要： Admission to a computer network is provided by having a network device listen to a communication channel communicatively coupling two or more components of the computer network. In some cases, the network device may then transmit a connection request to a controller of the computer network within a designated time slot of the communication channel. In other cases, the connection request may be transmitted without requiring the network device to be polled. The connection request may be confirmed by transmitting the connection request from the controller to network device periodically, until a response from the first network device is received by the controller. Upon confirmation, the controller may send to the network device, a connection agreements package, which includes information regarding time slots within the communication channel to be used by the controller for transmitting information to the first network device. The connection agreement packet may further include information regarding time slots within the communication channel to be used by the network device when transmitting information to the controller. Thus, during normal communications, data from the network device destined for the controller may be transmitted in the time slots designated in the connection agreement packet. In some cases, the information sent between the network device and the controller includes packets and, in such cases, the connection agreement may include information regarding a maximum number of bytes the network device can send or expect to receive in each packet, for each type of data included in a packet.
摘要翻译：通过使网络设备监听通信地耦合计算机网络的两个或多个组件的通信信道来提供对计算机网络的准入。在一些情况下，网络设备然后可以在通信信道的指定时隙内向计算机网络的控制器发送连接请求。在其他情况下，可以发送连接请求，而不需要轮询网络设备。可以通过从控制器周期性地向网络设备发送连接请求来确认连接请求，直到由控制器接收到来自第一网络设备的响应。在确认之后，控制器可以向网络设备发送连接协议包，该连接协议包包括关于要由控制器用于向第一网络设备发送信息的通信信道内的时隙的信息。连接协议分组还可以包括关于在向控制器发送信息时由网络设备使用的通信信道内的时隙的信息。因此，在正常通信期间，可以在连接协议分组中指定的时隙中发送来自控制器的来自网络设备的数据。在一些情况下，在网络设备和控制器之间发送的信息包括分组，并且在这种情况下，连接协议可以包括关于网络设备可以在每个分组中发送或期望接收的最大字节数的信息，对于每种类型包含在数据包中的数据。

摘要： Synchronization within a common communication channel having designated transmission time slots for various devices of a computer network is maintained by allowing transmissions within the channel outside of a network device's designated time slot when a clear channel assessment indicates that a previous time slot is not being utilized by its associated device and/or upon receipt of an indication of the end of a transmission of another device in the network. The clear channel assessment preferably takes into account the device's designated transmission time slot within the communication channel with respect to those of other network devices and may be a time period that is the product of a predetermined clear channel waiting time and a numerical representation of the device's designated transmission time slot within the communication channel with respect to those of other network devices. The clear channel waiting time itself may be specified by a network master device as part of a network connection process. The network device may be configured to construct one or more packets for transmission within the network in advance of its designated time slot to accommodate these early transmissions.
