Reject code handling is utilized for a more time-efficient selection of data-capable networks. One illustrative method for use in selecting a wireless communication network for communications involves the steps of selecting a first wireless network available for communications with the mobile station; causing a request for data connectivity to be transmitted to the first wireless network selected; if a rejection is received from the first wireless network in response to the request for data connectivity: reattempting the request for data connectivity to the first wireless network at least one time; selecting a second wireless network available for communications with the mobile station after the request for data connectivity to the first wireless network is reattempted the at least one time without success; and selecting the second wireless network available for communications with the mobile station without reattempting the request for data connectivity to the first wireless network the at least one time if a reject code associated with the rejection indicates that data services are not allowed in the first network is received from the first wireless network in response to the request for data connectivity.

Data-capable network prioritization with reject code handling

A system and method for addressing RLC unrecoverable errors experienced by User Equipment (UE) in a wireless network help the network to resolve the errors without shifting the UE into an Idle mode and dropping voice calls. A measurement event provides the buffer occupancy and identifies the affected radio bearer to the network. If the state of the bearer is not changed, the UE provides a Signaling Connection Release Indication message or a Radio Bearer Release Indication message to the network, the latter message identifying the radio bearer to be released without taking down the entire signaling connection for the domain.

An apparatus, and an associated methodology, for identifying to a circuit-switch-connected mobile station with an indication of packet-service capabilities available to a mobile station. A message generator at the network generates a message that includes an indication of the network-entity capabilities with respect to packet communications. A field of the message identifies the packet-service capabilities. A message is sent by the network and detected by a detector of the mobile station. A report is formed indicative of the value contained in the delivered message, and a user display displays an indication of the detected information.

Apparatus, and associated method, for informing dedicated mode connected mobile station of packet service capabilities in a coverage area

Network selection techniques for use in a mobile device which is configured for voice and packet data communications are described. The mobile device performs a scanning operation to identify one or more communication networks, and consults a network selection list for selecting, in accordance with assigned priorities of the list, one of the identified networks. The mobile device also determines whether a packet data service interconnection to a home network via the selected network is available. If the interconnection to the home network via the selected network is determined to be available, then the mobile device operates with voice and packet data services in the selected network. Otherwise, if the interconnection to the home network via the selected network is determined to be unavailable, then the mobile device repeats the acts of consulting and determining for the next identified network in the list.

Methods and apparatus for selecting a communication network

A network selection method for a mobile station which is associated with a Home Public Land Mobile Network (HPLMN) identified by a home Mobile Network Code (MNC) and Mobile Country Code (MCC) pair. The mobile station identifies a plurality of PLMNs in a geographic area, and selects a non-home PLMN identified by a non-home MNC/MCC pair and designated as a Registered PLMN (RPLMN). In response to regaining signal coverage from an out-of-coverage condition with the RPLMN, or being powered-on from a power-off s, tate entered while operating with the RPLMN, the mobile station selects the HPLMN if the HPLMN identified by the home MNC/MCC pair is available. Otherwise, if the HPLMN is unavailable and the RPLMN identified by the non-home MNC/MCC pair is available, the mobile station selects the RPLMN. However, if the RPLMN is unavailable, the mobile station selects an alternate PLMN in accordance with an automatic or manual network selection method.

A method for implementing call re-establishment using a user equipment (UE) configured to communicate with a wireless communication network includes detecting at least one of a radio link failure and a protocol failure of a connection between the UE and a serving cell. A target cell of the wireless communication network is selected and a received signal level for the target cell is compared to a signal level threshold. When the received signal level for the target cell exceeds the signal level threshold, call re-establishment is initiated on the target cell. The signal level threshold may be encoded within a system information type 21bis message, or a system information element. In some cases, the signal level threshold is equal to a minimum signal level required on the target cell.

System and method for call re-establishment

This application pertains to methods and apparatus to perform time zone determination by a mobile station.

Other examples are shown and described.

Methods and apparatus to perform time zone determination by a mobile station

A system and method for redirecting data from a host system (or messaging server) to one or more mobile data communication devices via a wireless packet data network is provided in which the wireless packet data network dynamically assigns addresses to the one or more mobile data communication devices on an as-needed basis. A redirector application operating at the host system is configured by each user to continuously redirect certain data to the wireless packet data network, as the data is received (or otherwise altered) at the host system. Two methods are provided for communicating the redirected data from the network to the mobile device. In a first method, the mobile device is configured to periodically contact a store-and-forward server within the wireless network, which, when contacted, assigns a network address to the mobile device and then transmits the stored, redirected data to the mobile device. In a second method, the network transmits a connection request command to the mobile device via a parallel voice network, or via a command channel, or other type of low-bandwidth data channel. The mobile device then contacts the data network and requests a network address so that the store-and-forward server can send the redirected data to the mobile device.
