摘要:
User Equipment (UE) receiving non-voice packet switched service in an Evolved Universal Mobile Telecommunications System Terrestial Radio Access Network (eUTRAN) cell undergoes handover to a circuit switched GSM/Edge Radio Access Network (GERAN)/UTRAN cell in response to a requirement for voice service. The voice service is established in the circuit switched domain of a GERAN/UTRAN cell to ensure service continuity regardless of UE mobility that would otherwise not be possible if the voice service was established in the eUTRAN cell. A Gs-like interface between a Mobile Switching Center (MSC) of the CS Core Network and the Mobility Management Entity (MME) of the Evolved Packet Core provides an interface for page requests and location update procedures to be performed.

User Equipment (UE) receiving non-voice packet switched services in an Evolved Universal Mobile Telecommunications System Terrestial Radio Access Network (eUTRAN) cell undergoes handover to a circuit switched GSM/Edge Radio Access Network (GERAN)/UTRAN cell in response to a voice service page. An eNodeB of the active eUTRAN cell uses a measurement report history for the UE to select an available circuit switched cell for handover. The voice service is established in the circuit switched domain of a GERAN/UTRAN cell to ensure service continuity regardless of UE mobility that would otherwise not be possible if the voice service was established in the eUTRAN cell. A Gs-like interface between a Mobile Switching Center (MSC) of the CS Core Network and the Mobility Management Entity (MME) of the Evolved Packet Core provides an interface for page requests and location update procedures to be performed.
摘要:
Methods and techniques for reducing both signaling and data traffic related to machine-type communication devices (MTC) in a GPRS communication network are disclosed. Optimized MTC messages from an MTC device are transmitted using Single-Block Packet Access procedures and restored by SGSNs based on a PDP context established during the mobile station's GPRS attach procedure.
摘要:
A system and method for providing an indication of a priority level of a non access stratum (NAS) message. In one aspect, a wireless communication device transmits a NAS signaling message together with a Packet Flow Identifier (PFI) information element that includes information indicating a priority level of the NAS signaling message. If the NAS signaling message has a low priority, the wireless communication device may receive a response message indicating that the ongoing NAS signaling message scenario can be performed less frequently in the future, thereby mitigating network congestion and radio interference.

A machine type device for deployment in a wireless network includes a processing circuit operable to generate an application layer message and a request including information identifying the machine type device as capable of using a particular protocol stack. After radio resources are setup between the machine type device and the base station controller, the processing circuit is further operable to transmit the application layer message and a local wireless network alias to a base station controller, the local wireless network alias indicating the machine type device is capable of using the particular protocol stack.
摘要:
A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN/UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN triggering initiation of the packet-switched handover from the GERAN/UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN/UTRAN cell.
摘要:
A method and packet data support node in a radio telecommunications network supporting packet data communication between a packet data network and a mobile terminal in radio communication with a first packet control unit. The packet data support node receives a message from the mobile terminal requesting handover to a second packet control unit. A packet flow context detector in the packet data support node detects the number of packet flow contexts currently active in the first packet control unit for supporting the packet data connection. The detector sends a message during handover to the second packet control unit indicating the number of active packet flow contexts. The message is used for activation of a corresponding number of packet flow contexts in the second packet control unit.
摘要:
Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Bandwidth in the second (or third) time slot can be used to carry information in a fast out-of-band channel (FOC). The FOC may provide information relating to the same connection as the payload or data field in that time slot, e.g., a service type identifier which informs the mobile or base station of the type of information (e.g., voice, video or data) being conveyed in the payload. Alternatively, the FOC information may be associated with a connection or connections which are different from that supported by the payload or data field containing the FOC.

A method for paging mobile stations in a communication system with a packet data control channel which is subdivided into master slots and slave slots is disclosed. First, each mobile station is assigned a paging slot, wherein the paging slot is a master slot. The system then pages one of the mobile stations on the paging slot assigned to the mobile station.
摘要:
Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Additional bits in the second (or third) time slot can be used to carry payload information which is not required to be transmitted at greater than full-rate. Moreover, FACCH information need only be transmitted in the master channel.
