摘要： The present invention relates to a method for improved and efficient usage of radio network resources with regard to the transmission properties of applied communication channel types and total network load by means of using early indications on the uplink or downlink of requests to establish new communication connection or adjust parameter settings of already existing connections regading the expectable amount of additional traffic due to such a connection. Early indications are, e.g., information on protocol type, the kind of requested communication service, the profile of the user equipment that has sent the request, or traffic history. In response to such indications the inventive method can forward, e.g., an uplink request and at the same time initiate a channel type switching providing appropriate channel parameter settings or adjustments. In case of congestion control it is another possibility to delay or even suppress uplink requests.

摘要： In the context of a radio communications system that includes a core network coupled to a radio access network (RAN) and a plurality of mobile terminals, a connection may be established between the core network and one of the plurality of mobile terminals through the radio access network. A temporary RAN identifier is associated with the mobile terminal for the established connection. The temporary RAN identifier is used to assist in the transfer of information pertaining to the established connection or to the establishment of that connection through the radio access network. The radio access network includes a first RAN node associated with a first geographical coverage area and a second RAN node associated with a second geographical coverage area. When the mobile terminal moves from the first coverage area to the second coverage area, the connection is re-established through the RAN by way of the first and second RAN nodes using the temporary RAN identifier. The temporary RAN identifier in packets corresponding to the established connection is used to direct those packets to and from the first and second RAN nodes. The first and second RAN nodes analyze packets corresponding to the established connection including the temporary RAN identifier included in each packet. From analysis of the temporary RAN identifier, the first and second RAN nodes determine where packets are to be routed. The temporary RAN identifier is also advantageously employed to facilitate mobile terminal registration and paging operations.

摘要： The present invention provides flexible radio access and resource allocation in a Universal Mobile Telephone System (UMTS). A UMTS Terrestrial access network (UTRAN) in response to a radio access bearer service request, flexibly and efficiently allocates resources necessary to support a communication with a mobile radio. The UTRAN includes plural base stations for communicating with mobile radios over a radio/air interface using radio channel resources allocated by a radio network controller connected to the base stations. External network service nodes interfacing with external networks communicate with the UTRAN over a radio access network interface. The UTRAN provides a radio access bearer service to the external network service nodes, and radio access bearers are dynamically assigned to radio channel resources by the UTRAN. When establishing each bearer, the UTRAN flexibly maps or allocates the radio access bearer to physical transport resources through the UTRAN and radio channel resources over the radio/air interface. In an example embodiment, the transport between nodes and the UTRAN includes an ATM connection, and a radio channel over the air interface includes one or more CDMA spreading codes. The mapping is based on one or more parameters including for example one or more quality of service parameters and/or current traffic conditions. In addition, if the one or more parameters changes during the life of the connection, the connection may be switched to a more appropriate channel type.

摘要： A telecommunications network has a target exchange (RNC 2222) which determines a congestion condition in a region supervised by the target exchange, and which sends a congestion message to a source exchange (RNC 2221). The source exchange controls at least some connections which utilize radio resources in the region supervised by the target exchange. The congestion message causes the source exchange to adjust at least one connection which it controls in the region supervised by the target exchange. In a first mode of the invention, the target exchange determines a selected connection to be adjusted in view of the congestion condition. In this first mode, the congestion message identifies the selected connection to be adjusted and further includes an adjustment value (e.g., power reduction value) for the selected connection to be adjusted. In a second mode of the invention, the congestion message includes an identification of a congested area (e.g., a cell) within the region supervised by the target exchange, as well as a severity value indicating a severity of the congestion in the congested area. The severity value can be indicative of a needed decrease in congestion in the congested area.

摘要： In a soft handover cellular system, diversity handling operations are multistaged for a mobile connection which is controlled by an original or Source RNC (1221) and which also utilizes a secondary or Target RNC (1222). Non-Source RNCs each have a diversity handling units (DHU) which perform connection splitting and connection combining operations for all involved base stations (BS) owned by the non-Source RNC, so that only one transport connection need exist between the Source RNC and the Target RNC for the mobile connection. The Source RNC (1221) has a diversity handover unit (1301) which not only performs connection splitting and connection combining with respect to the involved base stations owned by the Source RNC, but also with respect to the one transport connection for each Target RNC involved in the mobile connection.

摘要： Telecommunications network decision making (such as call admission and call congestion control) utilizes as input, not only information in the cell where the call is setup, but also cell condition information from cells which neighbor the cell where the call is setup. The cell condition information from neighboring cells is obtained even in situations in which the neighboring cell is controlled by another exchange, e.g., another radio network controller (RNC). In an illustrated embodiment, the cell condition information utilized by the decision making includes measured data taken over at least a multi-connection portion of cell, one example of which is radio interference information. The cell condition information utilized in the network decision making is transmitted between exchanges (e.g., between radio network controllers (RNCs)) using common channel signaling.

摘要： A radio access network portion of a telecommunications network (18) which serves a mobile station (MS) is connecting to a core network. The radio access network portion has plural base stations (BS) serving respective plural cells (C), as well as plural control nodes (RNCs). The control nodes include a first control node (RNC1) for controlling a first group of the plural base stations and a second control node (RNC2) for controlling a second group of the plural base stations. A multicell area (MCA) includes cells served by at least some of the first group of base stations and cells served by at least some of the second group of base stations. The radio access network portion of a telecommunications network further has a paging control node which stores information regarding the multicell area. To page the mobile station in the multicell area, the paging control node (1) sends paging messages to each of the base stations serving the multicell area controlled by the paging control node; and (2) sends a paging message to any other control nodes which control base stations serving cells in the multicell area. The paging control node determines to which base stations and other control node(s) it should send paging messages by consulting a paging table (100). Perferably the paging control node is one of the control nodes of radio access notwork. The paging control node is connected to the other control node(s) by an intercontrol node link (32) over which the paging message is sent.

摘要： An authentication mechanism renders a communications network impervious to unauthorized requests for interaction termination or cessation. In a release authentication mode of operation, the authentication mechanism protects against an unauthorized connection release message directed to a mobile node ( 30 ) of the network, e.g., a mobile station such as a user equipment unit, thereby thwarting an attempt to request an unauthorized connection release procedure concerning a connection involving the mobile node. In a detach authentication mode of operation, the authentication mechanism protects against an unauthorized detach message deceptively transmitted on behalf of a mobile node, thereby thwarting an attempt to request an unauthorized detach procedure for the mobile node. In its modes of operation, the authentication mechanism involves a first node (N i ) of the communications network at which authentication key is provided. The first node of the network uses the authentication key to derive an authentication indicia related to the authentication key. The first node (N i ) provides the authentication indicia to a second node (N r ) of the network. Subsequently, when an interaction termination operation is to occur (e.g., connection release or detach), the first node includes the authentication key in an interaction termination message transmitted over an air interface between the first node and the second node. As a condition for performing an interaction termination operation, the second node (N r ) confirms that the authentication key (which was included in the interaction termination message) is, in fact, related to the authentication indicia.
