A method () and an apparatus (e.g., a network node ()) for providing enhanced security using service provider authentication. In addition to authenticating an application signature () against a root certificate () stored on the network node (), a first carrier identification () associated with the application () is compared to a second carrier identification (). If the first and second carrier identifications match, then the application can be assigned to a trusted protection domain and granted permissions which provide privileged access to the network node. For example, the application can be granted permission to be installed and/or executed on the network node. Otherwise the application can be denied privileged access. Accordingly, a carrier's applications will be only installed onto network nodes that are intended recipients of the applications.

A system, method and computer readable medium for communicating data over a voice channel on a wireless device () is disclosed. The method on a wireless device () includes establishing an audio connection with a second device and providing an interface () for a user for sending data to the second device. The method further includes detecting the activation of the interface () by the user and sending a first data to the second device during the audio connection with the second device, wherein the quality of the audio connection is not affected by the sending. The method further includes receiving a second data from the second device, the second data being associated with the first data and preferably synchronizing the first data with the second data. Information, such as Vcard information, can be wirelessly exchanged between devices communicating data over a voice channel during an audio connection.

Simultaneous voice and data communication over a wireless network

A wireless domain ( ) sets a security policy for all mobile communication devices ( ) within the domain by use of a system entry proxy server ( ). A developer makes an application or code segment available at a developer station ( ). The application is certified by a certificate defining a developer security setting. The user of the mobile communication device initiates a download of the application so that it can be installed onto the mobile communication device. The application is downloaded through the system entry proxy server which authenticates the application, then re-certifies it with a compact certificate including an operator defined security policy. In this way the operator can control which resources of the mobile communication device are accessed by all applications coming into the wireless domain.

Method for validating an application for use in a mobile communication device

A signed application descriptor file ( ) is used instead of X.509 certificates to authenticate a portable application code, such as a JAVA archive (JAR) file. The signed ADF includes an application descriptor file ( ), file hash ( ) of the JAR file ( ), a developer descriptor file ( ), signed time stamp ( ), and a developer's certificate ( ). A network client device ( ) includes limited computing resources ( ) and a virtual machine environment for executing the portable code ( ). Furthermore the client device contains a set of cryptographic, digital keys for authenticating parts of the signed ADF, which are further used to authenticate the JAR file.

A method of conducting transactions in a wireless electronic commerce system, where the system comprises a wireless network operator certification authority ( ) having a root public key certificate and at least one attribute authority ( ) having a digital certificate that is dependent from the root public key certificate. The attribute authority is accessible by a wireless client device ( ) via a wireless network. The digital certificate is delivered from the attribute authority to the wireless device, the attribute authority is verified to the wireless client device using the digital certificate and the root public key certificate pre-loaded in the wireless client device under authority of the wireless network operator. An attribute (software, service, right/permission or other content item) is delivered to the wireless client device over the wireless network and ultimately enabled at the wireless client device.

A mobile communication device (,) communicates over a wireless bearer network which includes a base station (,) and a wireless communication system (,). To provision wireless application services the mobile communication device contacts a provisioning proxy (,) over the wireless bearer network, which in turns contacts a provisioning center (,) over a public network (,). A provisioning tunnel is then established between the provisioning center and the mobile communication device. Once the provisioning tunnel is set up, the user of the mobile communication device can subscribe to, or unsubscribe from wireless application services.

Method and apparatus for performing bearer independent wireless application service provisioning

A communication session is established between a client (,) and a server (,) over a first bearer network (,). A session identifier is produced (,), which is compressed (,). Messages or packets sent between the client and server during a first connection include the compressed session identifier and a first envelope identifier. At some time the first connection is terminated, and a second connection is initiated on a second bearer network. At the occurrence of the break, at both the client and server, a session transition control block is set up and includes the first envelope identifier. The session transition control block is used to map messages or packets received after the break to the correct session after resuming the session over a second connection with a second envelope identifier.

Method for providing seamless communication across bearers in a wireless communication system

A battery saving interval utilized for communicating with a portable subscriber unit (122) in a radio communication system is dynamically adjusted. An occurrence of a predetermined triggering event associated with the portable subscriber unit is observed (504), and the battery saving interval utilized for communicating with the portable subscriber unit is adjusted (506) in response to the predetermined triggering event, while battery saving intervals of other portable subscriber units in the system are left unchanged.

Method and apparatus for dynamically adjusting a battery saving interval

A method of wireless communication using a hybrid of a transaction protocol and a connection oriented protocol includes the steps of initiating a wireless request from a portable subscriber to a server using the transaction protocol (106) and continuing communications using the transaction protocol (110) if a response from the server is less than a maximum transfer unit size. If the response from the server is greater than a maximum transfer unit size, then the server segments the response into data packets, wherein the portable subscriber unit and server subsequently communicate using the connection oriented protocol (114) until a subsequent wireless request is made from the portable subscriber.

Wireless protocol method and apparatus supporting transaction requests

A selective call receiving device (10) such as a pager is controlled to dynamically change a base frame assigned to the device and subsequent control frames derived therefrom. The time that the device is operative to look for its address in a received signal can thus be dynamically changed to improve the efficiencies of a mixed systems environment without substantially reducing the battery life of the selective call receiving device (10). In two embodiments of the invention a new base frame for the device is derived from an originally assigned base frame that is stored in the selective call receiving device. In another embodiment, a new base frame for the device is derived from the device's address along with frame management information that is received by the selective call receiving device.

Method for dynamically changing control frames for selective call

Traffic in a radio communication system (FIG. 1) is adaptively balanced (300) to control congestion. A congestion model is maintained (302) with congestion dependencies including first and second types of congestion along with corresponding likelihood functions that indicate a likelihood that the first type of congestion will lead to the second type of congestion. An early warning of an impending congestion is detected (304) from an incoming traffic mix which exceeds an output traffic capability, given a current output allocation and configuration. The congestion model is accessed (306), in response to detecting the impending congestion, to identify and determine a priority for possible sources of the impending congestion. Action is then taken (308, 314, 318) to relieve the impending congestion by doing at least one of (a) increasing output resources and (b) decreasing traffic rates from the possible sources, prioritized in accordance with the congestion model.
