Abstract: Control circuitry is configured to control a sampler, in a sampling phase determination process, to sample a signal at a sampling period of T±T/n for outputting a sample set for each one of n phases of the sampled signal. Each one of n correlators has a first input configured to receive one of the sample sets, a second input configured to receive a PN signal, and an output which provides a correlation result from a correlation process between the sample set and the PN signal. The control circuitry is further configured to identify, from the correlation results, one of the phases associated with the optimal correlation result. The control circuitry is then configured to control the sampler, in a communication mode, to sample a received signal at a sampling period of T at the phase associated with the optimal correlation result.

Abstract: In one illustrative example, a mobile communication device receives and decodes a plurality of packet data bursts over a packet data channel of a serving cell. While receiving and decoding the packet data bursts, the mobile communication device also receives and decodes a plurality of broadcast data bursts over a broadcast control channel of a neighbor cell. When a time conflict exists between receiving and decoding at least one of the packet data bursts and receiving and decoding at least one of the broadcast data bursts, the mobile communication device receives and decodes the at least one packet data burst instead of the at least one broadcast data burst when no imminent call drop between the mobile communication device and the serving cell is identified.

Abstract: A mobile device is engaged in a connected data service via a wireless network. The connected data service utilizes a radio traffic channel established between the mobile device and the wireless network and a data session for communicating data. While engaged in the service, the mobile device receives via a user interface a voice call request for initiating a voice call. In response to the request, the mobile device permits the initiation of the voice call. Specifically, the mobile device causes the radio traffic channel for the connected data service to be torn down without terminating the data session. The mobile device also causes the voice call to be established and maintained over a new radio traffic channel via the wireless network while the data session for the data service is maintained.

Abstract: For each one of a plurality of broadcast control channels, a mobile device measures a signal strength level of a radio frequency (RF) signal from a wireless communication network. The mobile device then repeats the measuring at least one time so that at least one other signal strength level of the RF signal on the broadcast control channel is identified. The mobile device also receives and decodes information which is broadcasted on the broadcast control channel, and stores this broadcasted information in memory. The acts of receiving, decoding, and storing are performed after measuring the signal strength level of the RF signal, but prior to completion of an averaging function for calculating an averaged signal strength level of the signal strength levels.

Abstract: A mobile device operates in a WLAN for VoIP communications, which includes registering with registrar server functionality of a SIP proxy server with a SIP identity which is further communicated to a location server. In response to an incoming voice call from a caller via a telephone network, the mobile device receives an INVITE request which is issued from a gateway and forwarded from the SIP proxy server. The mobile device sends a response to the SIP proxy server which is communicated to the caller via the gateway. When switching from the WLAN to the cellular network, the mobile device sends via the WLAN to the location server a message for forwarding voice calls directed to the SIP identity to the telephone number. The mobile device also sends via the cellular network a message for canceling the forwarding of voice calls directed to telephone number to the SIP identity.

Abstract: In one illustrative example, a mobile device receives from a relay services node an enable message which indicates a pending data message to be retrieved from a host service. The pending data message may comprise a body of text. Subsequent to the receiving of the enable message, a messaging application is opened at the mobile device. In response to the opening of the messaging application, the mobile device communicates directly with the host service without use of the relay services node, for retrieving the pending data message from the host service via a wireless network.

Abstract: In one illustrative example, a magnetic storage device includes a three terminal magnetic sensor having a collector region made of a semiconductor material, a base region, and an emitter region. An insulator layer is formed between the collector region and a slider body which carries the three terminal magnetic sensor. The insulator layer serves to reduce a capacitance otherwise present between the collector region and magnetic media at a magnetic field sensing plane of the three terminal magnetic sensor. Thus, the insulator layer electrically isolates the collector region from the slider body. The structure may be formed through use of a separation by implanting oxygen (SIMOX) technique or a wafer-bonding technique, as examples.

In response to a communication loss between the wireless device and the wireless network which causes the data connection to be terminated, the server receives from the application server a plurality of connection requests which are intended for receipt by the wireless device for re-establishing the data connection. The server operates to limit the number or a rate of the connection requests allowed to pass from the server to the base station of the wireless network during the communication loss between the wireless device and the wireless network.

Abstract: Techniques in a wireless device for use in providing restrictions on communications via a cellular network are described. The wireless device communicates with a host enterprise server of a private network which is external to the cellular network for performing data synchronization in association with a personal information manager (PIM) application. The wireless device receives communication restriction information from this same host enterprise server in the private network, and stores this information in its memory. The wireless device determines whether a communication is restricted by comparing a user selected code of a communication attempt with one or more codes of the stored information. If the communication is determined to be restricted, the wireless device disallows the communication via the cellular network. If the communication is determined to not be restricted, the wireless device may allow the communication via the cellular network.

A communication network receives a broadcast message which includes a protocol type identifier in a protocol type identifier field. The communication network identifies whether the protocol type of the broadcast message matches one of a plurality of protocol types stored in association with an identification of the mobile device. If the protocol type of the broadcast message matches one of the stored protocol types, then the communication network produces, from the broadcast message, a unicast message which includes information from the broadcast message, and causes the unicast message to be sent to the mobile device in the wireless network.

Abstract: In one illustrative example, a network name displaying method utilizes a home network list and a preferred network list. The home network list identifies a plurality of home networks, and the preferred network list identifies a plurality of non-home roaming networks. An identification of a selected wireless network is compared with a plurality of home network identifications corresponding to the plurality of home networks. A home network display name is displayed in response to identifying a match between the identification of the selected wireless network and any one of the home network identifications. On the other hand, an alternate display name corresponding to the non-home roaming network is displayed if there is no match between the identification of the selected wireless network and the home network identifications.

Abstract: A communication device reads and stores in memory a state value which was utilized for operating a communication subsystem during a wake-up period of the communication subsystem. The device then causes the communication subsystem to enter into a sleep mode. Subsequently, the device causes the communication subsystem to exit from the sleep mode and enter into a current wake-up period. The stored state value is provided to the communication subsystem for use in operating the communication subsystem during a warm-up period of the current wake-up period. After the warm-up period of the current wake up period, a current state value is provided from a state controller to the communication subsystem for use in operating the communication subsystem during the wake up period. The current state value is determined based on a detected signal level of a current signal received in the communication subsystem.

Abstract: A mobile device sends to a wireless network a request for establishing a service. In response to a rejection of the request, the device reattempts the request so long as the total number of requests is less than a predetermined value. When the total number of rejected requests is greater than or equal to the predetermined value, the device selects a different wireless network with which to establish the communication service if the wireless network is a non-home network. Otherwise, if the wireless network is the home network, the mobile device runs a timer which is initialized with an internal timer value instead of a network timer value when the internal timer value is less than the network timer value. In response to an expiration of the timer, the mobile device sends to the wireless network another one or more requests for establishing the service.

Abstract: Techniques for use in a network processing component is for initially establishing, via a gateway, a voice call between a mobile device which operates in a wireless network and a destination device. A first connection leg of the voice call is to be established between the mobile device and a conference room of the gateway. The technique involves sending to the gateway a request message for establishing a second connection leg between the network processing component and the destination device, and then subsequently sending to the gateway a re-routing message for re-routing the second connection leg from the network processing component to the conference room. This causes a voice call having the first and the second connection legs to be initially established between the mobile device and the destination device via the gateway.

Abstract: A communication device receives an incoming call message for an incoming call. The incoming call message has data indications indicating whether the incoming call is an emergency call from a public safety answering point entity. If the data indications do not indicate that the incoming call is an emergency call from the public safety answering point, then the communication device performs non-emergency call processing for the incoming call. On the other hand, if the data indications indicate that the incoming call is an emergency call, then the communication device causes the emergency call to be answered automatically.
