Techniques for filtering broadcast SMS messages at a mobile station based on network configuration, user configuration, and/or user preferences. In one method, a broadcast message is initially received, and one or more filtering criteria are applied to the received broadcast message. The filtering criteria are defined by settings stored in a removable module (e.g., the R-UIM) coupled to the receiver. The received broadcast message is then processed if it is not filtered out by the one or more filtering criteria. The one or more filtering criteria may include (1) those imposed by a service provider and defined in a network configuration setting, (2) those determined by the mobile user and defined in a user configuration setting, (3) those selected by the mobile user based on user preferences, which allow for filtering of broadcast messages based on service category, language, and priority, or (4) any combination of the above.

Techniques to send GSM CBS messages over a CDMA air interface. The encapsulation of a GSM CBS message in CDMA messages may be achieved using various schemes. An indication is provided at each of a number of pertinent layers to allow the terminals to determine whether a GSM CBS message or a CDMA broadcast SMS message was sent. These indications include (1) a value in a designated field or subfield of a Data Burst Message, (2) a new value for a Category field in a Service Category parameter of an SMS Broadcast Message, and (3) a new value for a Msg_Encoding field in a User Data subparameter of the SMS Deliver Message.

Method and apparatus for updating roaming lists. An error handling message is provided when the roaming list protocols within the elements of a system are not compatible. A roaming list format identifier is provided to the remote user identifying the protocol version supported by the network. The roaming list format identifier acts to either request an old version of the protocol or request the current stored format at the remote user. In one embodiment, the old version is the Preferred Roaming List, and the new version is the Extended Preferred Roaming List.

Techniques for downloading and displaying system tags by wireless terminals based on roaming status. A tag includes texts and/or graphics. The system tags include home system tags and roaming system tags, which include group tags and specific tags. A home system tag is associated with one or multiple home systems, a group tag is associated with one or multiple roaming indicator values, and a specific tag is associated with one or multiple SID values. A terminal is provided with home system tag, group tags, and specific tags. The terminal displays the home system tag when obtaining service from the home system and a roaming system tag when obtaining service from a roaming system. The particular roaming system tag to be displayed is dependent on the roaming indicator value and the SID value for the roaming system. The system tags may be downloaded to the terminal via over-the-air signaling.

A preferred roaming list (PRL) carries system and acquisition records for wireless wide area network (WWAN) systems and wireless local area network (WLAN) systems. New system and acquisition records may be defined for WLAN. The PRL and system and acquisition records may be defined to be backward compatible with TIA-683-C. System and acquisition information for WLAN systems may be stored in the new system and acquisition records, respectively. Information used to perform encryption and/or authentication for WLAN systems may be stored in a separate WLAN authentication profile table. The system record for each WLAN system indicates a acquisition record and a profile record for that WLAN system. A network identifier table may also carry system records and profile records for WLAN systems. The system records carry information used for WLAN system selection and acquisition. The profile records carry information used to perform encryption and/or authentication for WLAN systems.

A network operator identifier is used to uniquely identify each network operator to support international roaming. The network operator identifier includes (1) a Mobile Country Code (MCC) that identifies the country in which a network operator belongs and (2) a Network Operator Code (NOC), which may be a Mobile Network Code (MNC), that distinguishes network operators within a given MCC. Each network operator is assigned a unique combination of MCC and NOC that distinctly identifies the network operator, and the network operator identifier can be stored in a single entry in a preferred roaming list. The base stations of each network operator broadcast the network operator identifier in signaling messages. A mobile station receives a signaling message from a base station, obtains the network operator identifier, searches its preferred roaming list for an entry with the network operator identifier, and determines whether or not the current CDMA network is accessible.

Network operator identification for CDMA communication networks

Techniques for conveying reports for SMS messages in wireless communication networks that utilize CDMA air interface (e.g., GSM1x and CDMA networks). Two new messages SMS Deliver Report Message and SMS Submit Report Message are defined for CDMA SMS. These report messages may be used to more fully convey the information in the SMS-Deliver-Report TPDU and SMS-Submit-Report TPDU defined in GSM SMS. A new Report_Req field is also provided in the Reply Option subparameter of the SMS Deliver Message and SMS Submit Message defined in CDMA SMS. This new field may be used to request a report for an SMS message to be sent by the message's recipient. Each report message may include (1) a first value indicative of whether the SMS message was received correctly or in error, (2) a second value indicative of a type of error, if any, encountered for the SMS message, and (3) user data.

Techniques for converting short messages between different formats (e.g., from GSM SMS to CDMA SMS) such that pertinent control information is retained without changing the fundamental structure of these message formats. A new value is defined for the Msg_Encoding field in the User Data subparameter of the CDMA SMS message to indicate that the content of this message is an encapsulated GSM SMS message. The Message_Type field in the User Data subparameter may be used to carry data coding scheme information for the encapsulated GSM SMS message. At a recipient mobile station, the value in the Msg_Encoding field is checked to determine whether or not the CDMA SMS message includes an encapsulated GSM SMS message. If the answer is yes, then the user data in the CHARi fields of the CDMA SMS message is processed based on the data coding scheme information from the Message_Type field.

Short message conversion between different formats for wireless communication systems

Method and apparatus for providing provisioning parameters to a mobile device. A short messaging service message is used to send bootstrap data sufficient to establish communication between an Internet Protocol-based server and a mobile device. The mobile device then establishes such communication and the provisioning parameters from the Internet Protocol-based server.
