摘要： A method and apparatus for use in a mobile communications system having a plurality of cell segments includes allocating a plurality of channels to perform communications and defining a plurality of time groups. A channel reuse pattern is provided that is based on the plurality of channel frequencies and the plurality of time groups. Control channels are carried in a different time slot of a frame in each time group. Predetermined time slots are allocated as guard periods to reduce likelihood of interference of signaling due to overlap of time slots in neighboring cell segments. In one arrangement, three channel frequencies are allocated. Further, three or four time groups are defined to provide an effective 3/9 or 4/12 channel reuse pattern. In each time group, control channels are carried in odd time slots of a time-division multiple access (TDMA) frame. The even time slots are employed as guard periods to reduce likelihood of interference caused by overlapping time slots, which may occur in relatively large cells because of propagation delays in communications between mobile units and base stations.

摘要： A mobile communications system includes a first link and a second link (e.g., a circuit-switched link and a packet-switched link). When a mobile unit is initialized in the mobile communications system, it identifies a first control signal, such as the digital control channel (DCCH) of an IS-136 system, of the first link. From information associated with the first control signal, the mobile unit determines the existence of the second link (e.g., according to 136 HS). From information identifying a current frame structure in the first link, a pointer to the current frame structure of the second link can be derived.

摘要： A wireless network includes wireless access systems for communicating with mobile stations. At least one of the wireless access systems is capable of communicating with multiple types of mobile stations. One type of mobile station communicates according to the Enhanced General Packet Radio Service (EGPRS) protocol, while another type of mobile station communicates according to the GSM/EDGE Radio Access Network (GERAN) protocol. The wireless access system includes control logic to select one of plural types of protocol stacks to use for communications over an air link with the different types of mobile stations. In response to an indicator of a first type, the wireless access system selects a first protocol stack, and in response to an indicator of a second type, the wireless access system selects a second protocol stack.

摘要： A mobile communications system includes a radio access network, such as an Enhanced General Packet Radio Service (EGPRS) network, in which mobile stations are able to enter into a discontinuous transmission (DTX) mode. During DTX mode of a first mobile station that is allocated a channel portion (e.g., a time slot of a frame), the radio access network is able to multiplex traffic from another mobile station onto the same channel portion. A mechanism is provided to enable the first mobile station to send a request for re-allocation of the channel portion. The request includes a Real-Time FastAssociated Control Channel (RTFACCH) resource request message (RTRRM). In response to the RTRRM, the radio access network sends an RTFACCH resource assignment message (RTUAM).

摘要： A mobile communication system includes cell segments each associated with a base station. The base station includes transceivers capable of communicating over two sets of carriers. A first set of carriers carry circuit-switched traffic, while the second set of carriers carry packet-switched data. Co-channel interference measurements are made by mobile units or by a serving base station in each cell segment during communications of active bursts of traffic or control signaling. Such bursts may include a training sequence that is used by the measuring device to recreate a burst without interference contributions. Co-channel interference is then determined based on the recreated bursts and the received bursts. Multiple interference values may be derived and applied to an averaging filter to calculate the final interference contribution value.

摘要： A method and apparatus for managing radio resources in one or more wireless communication networks. At least one radio resource manager (RRM) is provided within a network node, or as an independent entity. The RRM monitors performance on wireless communication links of the network(s) and interacts with nodes associated with those links to change the configuration on a particular wireless communication link if its performance (i.e., quality) falls below an established threshold. Information regarding current resource usage of the network is sent to the RRM by the nodes. Each of the nodes may send a quality report to the RRM including wireless communication link quality measurements and performance statistics. Alternatively, the RRM may perform the wireless communication link quality measurements. The RRM facilitates the broadcasting of information regarding current resource usage of one network to other networks to avoid collisions and interference.
