A Mobility Management Entity (MME) of a wireless network and verification method for verifying a Channel Quality Indicator (CQI) of a roaming Wireless Communication Device (WCD) are provided. The MME in one example includes an interface configured to receive a roaming request of the roaming WCD and a processing system coupled to the interface. The processing system is configured to obtain a home CQI of the roaming WCD, compare the home CQI to a contract-stipulated CQI for the roaming WCD, and use the contract-stipulated CQI for the roaming WCD if the home CQI differs from the contract-stipulated CQI.

CQI verification for a roaming WCD

A method for a setting up a conference call with a mobile station and an intermediary mobile station, using the intermediary mobile station as a bridged-node. When a conference server receives a request to setup a conference call, the conference server initiates conference setup signaling with both mobile stations using a cellular link. The conference server uses the conference setup signaling to direct one mobile station to act as a bridged-node and the other mobile station to act as a bridged-leg. Responsive to the directives, the bridged-leg mobile station and the bridged-node mobile station establish a Wi-Fi link. The bridged-leg mobile station then uses the Wi-Fi link to bridge to an air traffic channel associated with the bridged-node mobile station.

Systems, methods, and computer-readable media for alleviating and overriding throttled conditions in Long Term Evolution networks are provided. In embodiments, indications that throttled conditions have been reached are received at Mobile Management Entities. Cause codes are communicated, in embodiments, to mobile devices directing the mobile devices to refrain from further attach attempts. In embodiments, attach attempts associated with unique identifiers are received by the Mobile Management Entities that override throttled conditions. In embodiments, authentication failure conditions from the Mobile Management Entities are detected. Algorithms are invoked, in embodiments, to initiate cell barring modes for base stations and detect failure percentages.

Alleviating and overriding throttled conditions in LTE

Disclosed are a method, apparatus, and system for managing connections in a wireless communication network. When a user equipment device (UE) transitions between an idle state and an active state, a radio link is established between a base station and the UE and a core network link is established between the base station and a core network entity. In response to detecting that no data packets are exchanged between the UE and the base station, a timer is initiated. Further, in response to detecting that data packets are being exchanged between the UE and the base station, the timer is reset. The radio link is released in response to the timer reaching a first predetermined value associated with a first inactivity period and the core network link is released in response to the timer reaching a second predetermined value associated with a second inactivity period.

Method and system for reducing frequent connection establishment requirements between network elements

Methods of determining and providing location information as to the whereabouts of a wireless device are disclosed which have less geographical precision that those based on GPS or triangulation algorithms, but which are much more scalable, efficient and less costly. The methods make use of SMS paging and in particular obtain cell and cell sector information from a wireless device from a response message to an SMS page to the device. The cell and cell sector is converted to user-friendly geographical information such as an address or name of a building using a database correlating cell sectors to landmarks, location or addresses, and this user-friendly information is returned to the requestor.

Highly scalable, lower precision idle mode locating method for wireless devices

A mobile node in communication with a first wireless system detects a handoff condition and responsively transmits a handoff request to a handoff controller. In response to the handoff request, the handoff controller selects a second wireless system for the mobile node and establishes a packet registration with the second wireless system on behalf of the mobile node. When the registration process is completed, the handoff controller transmits a handoff instruction to the mobile node. The mobile node may then acquire a radio link with the second wireless system and use the packet registration established by the handoff controller to send and/or receive packets via the second wireless system.

Method and system for handoff controller-mediated handoff of a mobile node

Methods and systems are provided for network-side setup of a packet-data communication session on behalf of a mobile station, followed by transfer of the communication session to the mobile station. A radio access network (RAN) receives from the mobile station an origination message comprising a code and a called-party identifier, the code indicating that the mobile station is requesting that, on behalf of the mobile station, the RAN set up a packet-based communication session between the mobile station and an endpoint associated with the identifier. Responsive to the origination message and on behalf of the mobile station, the RAN sends to the endpoint an invitation to participate in the communication session. Responsive to the endpoint accepting the invitation, the RAN sends to the mobile station information enabling the mobile station to engage in messaging with the endpoint related to the communication session and/or participate in the communication session with the endpoint.

Network-side setup of a packet-data communication session on behalf of a mobile station, followed by transfer of the communication session to the mobile station

A method and apparatus for transitioning between radio link protocols in a packet-based real-time media communication system. A wireless communication device such as a cell phone will operate under one radio link protocol (such as IS-856, also known as 1xEV-DO) to engage in packet-based signaling for setup of a packet-based real-time media session such as a push-to-talk session. Once the session is set up, the wireless communication device will then automatically transition to operate under a different radio link protocol (such as IS-2000, also known as 1xRTT), and will engage in packet-based real-time media communication in the session over that different radio link protocol. Preferably, the radio link protocol used for session setup signaling will provide for reduced setup latency, while the radio link protocol used for bearer communication in the session will provide for reduced jitter and improved real-time media communication.

A parent mobile station is provided that enables real-time parental control over communications with an associated child mobile station. The parent mobile station receives notification of attempted inbound and outbound calls with third parties to and from the child mobile station, or of requests from the child mobile station to retrieve content from a content provider. In response to the notifications, the parent mobile station determines whether or not to permit the inbound and outbound calls or the retrieval of content. If permitted, communications with the child mobile station are routed through the parent mobile station, which itself communicates over a wireless telecommunications network. If not permitted, the parent mobile station does not relay such communications. The child mobile station preferably communicates with the parent mobile station using a wireless local area network (WLAN) or Bluetooth protocol and is preferably incapable of defeating the parental controls with a direct connection to the wireless telecommunications network.

Handset based dynamic parental controls

A method for a setting up a call to a mobile station using an intermediary mobile station. The intermediary mobile station is a multi-mode device that may exchange data according to at least two different protocols. One protocol is a cellular communication protocol, such as CDMA. A second protocol is a WLAN protocol, such as 802.11. When a RAN attempts to setup a call with a first mobile station and the call attempt fails, the RAN establishes a cellular wireless link with the intermediary mobile station instead, and the intermediary mobile station establishes a WLAN link with the first mobile station. Call setup and bearer communication may then proceed between the RAN and the first mobile station with the intermediary mobile station functioning as a wireless bridge.
