Methods enable a paging service and a media service to be carried on a single carrier frequency. The methods includes: determining to send a paging record to a communication device for a first media service, wherein the first media service is provided on a first carrier frequency; inserting the paging record into a first message generated using a protocol that is also used to provide a second different media service to the communication device on a second different carrier frequency; providing a paging indication using the protocol; and sending the paging indication and the first message with the paging record over the second carrier frequency. The protocol can be a multimedia broadcast service (MBMS) protocol. The paging indication alerts the communication device to monitor the second carrier frequency for the paging record.

A method and apparatus for service continuity on a mobile communication device is disclosed. The method can include receiving () a first service on a first carrier, where the first service can have a multicast subframe allocation pattern. The method can include establishing () a connection on a second carrier on a universal mobile telecommunication system. The method can include informing () a source of the second carrier of the multicast subframe allocation pattern of the first service. The method can include receiving () scheduling grants for subframes on the second carrier. The subframes corresponding to the received scheduling grants can be distinct from subframes corresponding to the multicast subframe allocation pattern of the first service. The method can include receiving () a second service on the second carrier based on the scheduling grants while receiving the first service on the first carrier.

Method and apparatus for service continuity on a mobile communication device

A wireless communication terminal and a corresponding method therein includes initiating a first radio link control reset procedure, and receiving a message after initiating the first radio link control reset procedure and before the first radio link reset procedure is complete, wherein the message contains an instruction to set a protocol data unit size. A second radio link control reset procedure is initiated after setting the protocol data unit size.

Establishing radio link control in wireless communication networks

A method in a communication device () providing data services over a packet access radio interface comprises monitoring () a control channel for signalling messages for data packets for the communication device, receiving data packets for a data service of a first type with a first periodicity and receiving () data packets for the data service of a second type with a second periodicity, the second periodicity being greater than the first periodicity. The method further comprises selecting () to not monitor the control channel for signalling messages for a period of time in response to detecting a data packet of the second type received by the communication device. A communication device is also described.

Method in a communication device providing data services over a packet access radio interface and a communication device

A network controller or base station (), allocates resources and indicates a minimum priority level below which, mobile stations may not transmit data via messaging (). Messaging () may be a scheduling message in some embodiments. The network controller or base station () also communicates a data timer setting for timing sub-minimum priority data via messaging (). Messaging () may be a control message in some embodiments. The mobile station () responds by setting a data timer () and holding data with a priority below the specified minimum. Before the timer times out, the mobile station () may transmit data on granted resources via () provided its priority level is above the specified minimum. After timer expiration, the mobile station () may transmit its low priority data, or combinations of high and low priority data ().

Apparatus and method for uplink scheduling on shared channels

Mobile station applications () may include an SI unit () for piggy backing SI onto data stored in data buffer () and also for adding an indicator to the SI information. The scheduling information and/or incremental control information () is piggy backed onto a data PDU and also has a sequence number () and an indicator field () which is added by the SI unit, such as SI unit (), in accordance with the embodiments. The indicator may be a bit map having four bit positions. A bit position having a binary '1' value may be utilized to indicate that a previous SN of SI information remains valid. For example, '0100' of the bit map sequence may indicate that SN #is still valid. The base station or controller may then determine whether to implement or discard an SI information having the indicated SN.

Apparatus and method for transmitting uplink control information on shared channels

A security mode method () receives () a layer 3 message in a first domain from a network, determines () if the layer 3 message has integrity protection information, ascertains () if a security mode has been initiated in the first domain, and forwards () the layer 3 message to an upper layer, if the layer 3 message lacks integrity protection information and a security mode has not been initiated in the first domain even if security mode has been initiated in a second domain. This method allows a mobile station to process a non-integrity-protected layer 3 message from one domain even if integrity protection has been initiated in another domain. When packet-switched and circuit-switched connections are being concurrently set up, a non-integrity-protected message in one domain may arrive at a mobile station after an integrity protection initiation message in another domain.

Mobile station security mode method

A wireless communication terminal () including a radio transceiver (), and a radio link control entity () that re-initiates a radio link control reset procedure when the transceiver receives a message containing an instruction to change an uplink or downlink protocol data unit size during an ongoing radio link control reset procedure. For example, the radio access network may initiate an uplink or downlink PDU size change before terminal receives acknowledgement that a previously initiated radio link control reset procedure is complete. The radio link control entity restarts a radio link control reset timer upon re-initiating the radio link control reset procedure after re-establishing radio link control.

If there is a radio link failure condition () between a user equipment () and a network () during or after a reconfiguration process, a cell update process with reconfiguration status indicates whether a user equipment reconfiguration is complete. If the network () receives an indication that the user equipment reconfiguration is complete, either through a stand-alone reconfiguration complete message () or a status indicator of a cell update message () from the user equipment (), the network () proceeds in accordance with the current configuration.

Cell update process with reconfiguration status

An integrity protection count synchronization method () initiates () a new connection when a user equipment (UE) is already in connected mode with a network. If new security keys are pending, the UE sends () a START value of zero in an initial direct transfer message. If no new security keys are pending, the UE sends () a non-zero START value based on a Universal Subscriber Interface Module (USIM). Sending a START value of zero when new security keys are pending at the UE forces the network's COUNT-I integrity count value to match the zero COUNT-I value at the UE, which prevents call set-up failure due to inability to pass an integrity protection security check.
