A method as described by which an application executing in an application layer of a multi-layer communication protocol forming part of a general packet radio service (GPRS) session can signal for the setup and release of Temporary Block Flow (TBF) which will not be released during application execution in silent (inactive) periods. When applications such as voice, telnet or web browsing have specific traffic type data that have inactive periods between active periods are to be carried over GPRS, the session consists of multiple active periods. Current TBF release procedures lead to multiple TBF setups during such sessions. With the method described, a special type of TBF can be set up with special procedures for release of this TBF which greatly minimizes the need for multiple TBF setups during a session containing data transfers with inactive periods between active data transmissions.

A method of filtering data packets in General Packet Radio Service (GPRS) Tunneling Protocol (GTP) signaling messages. Selected messages from GTP Path Management, GTP Tunnel Management, GTP Mobility Management, and GTP Location Management messages are analyzed against a plurality of filtering criteria, and data packets that do not meet the filtering criteria are dropped while data packets that meet the criteria are passed. The data packets may be analyzed to verify that they contain correct source, destination, and mask addresses, and that they contain UDP/TCP port numbers that are consistent with the GTP version number. The packets are also inspected at the GTP level, layer-5, and based on the GTP version, information in the GTP header, and accompanying Information Elements (IEs), selected data packets are dropped.

In a General Packet Radio Service (GPRS) network, a system and method of dynamically allocating an Internet Protocol (IP) address to a mobile terminal (MT) operating in the network. A Gateway GPRS Service Node (GGSN) requests IP addresses over the Gi interface from a Radius server in an IP-based network. A Conditional PDP Address (CPA) parameter is stored in the MT's Home Location Register (HLR) as part of the user subscriber data, and is passed to the GGSN during the GPRS Attach procedure. The CPA parameter indicates whether the subscriber is entitled to a backup IP address in case of failure to obtain one over the Gi interface, and whether the MT is a user of a real-time application. A timer in the GGSN sets a maximum time period (Ti) that the GGSN will wait for a response from the server, and a counter (Ni) sets the maximum number of requests that are sent. A Network Access Server (NAS) in the GGSN sends a request for an IP address from the GGSN to the server, and determines whether Ti expires without receiving a response from the server. If no response is received, the GGSN allocates an IP address. A public IP address is allocated only if the MT is a user of a real-time application. Otherwise, a private IP address is allocated.

An improved method and system for accessing wireless data services that reduce messaging and enable roaming subscribers to access data services are described. A wireless communication system in accordance with the present invention includes at least a service control point and a gateway system (e.g., a Gateway Generalized Packet Radio Service Serving Node (GGSN)) that is coupled to a data network. To obtain access to data services, a wireless subscriber unit establishes communication with a gateway system and requests data services from the gateway system. In response to the request, the gateway system queries the service control point regarding authorized data services for the subscriber unit. If the gateway system receives a negative reply from the service control point, then the gateway system denies access to the data services by the subscriber Unit. However, if the gateway system receives a positive reply from the service control point, then the gateway system enables access to the data services by the subscriber unit. In a preferred embodiment, the gateway system tracks the requested data services utilizing pre-defined resource units. In one embodiment, the gateway system tracks service utilization by periodically querying and receiving a reply from the service control point after each pre-defined resource unit has been utilized. In this embodiment, the service control point updates an account balance of remaining resource units in response to receiving the queries and informs the gateway system when data access should be denied.

A Home Location Server (HLS) and method of processing an incoming real-time call to a Mobile Station (MS) in a hybrid radio telecommunications network having both second generation (2G) and third generation (3G) service nodes. When a request for location information for the called MS is received in the HLS from an interrogating switch where the incoming call originated, the HLS determines whether the called MS is located in a 2G Mobile Switching Center (MSC), or a 3G Call State Control Function (CSCF). If neither, the HLS concludes that the called MS is located in an Serving General Packet Radio Service (GPRS) Support Node (SGSN). A 3G flag, which is set in the subscriber profile when the MS registers with a 3G SGSN, is checked to determine whether the SGSN is a 2G SGSN or a 3G SGSN. If the SGSN is a 2G SGSN, the HLS informs the interrogating switch that the MS is not available for the real-time call. If the SGSN is a 3G SGSN, the HLS orders the SGSN to page the MS and determine whether the MS accepts the incoming call.
