摘要:
Solutions are described that enable a user equipment (UE) for a communication system always to derive required identifiers using an international mobile subscriber identity (IMSI) even when the UE has only a subscriber identity module. One solution is based on a table, or list, that is maintained in the UE. Another solution is based on always taking a predetermined number of digits of the IMSI. Yet another solution is based on try-and-fail signaling. In consequence, the UE does not always need to know how many digits of the IMSI are used to indicate a mobile network code, which in some situations is impossible to know anyway.
摘要:
A technique is provided for use by a user terminal or mobile services switching center (MSC) for responding to a request to switch an on-going call from speech mode to multimedia mode within a wireless communication network conFig.d to automatically disconnect a call if a requested mode switch is not confirmed within a predetermined period of time specified by a call drop timer. In one example, the terminal or MSC activities an automatic response timer upon receipt of a request from a user to switch an on-going call from speech to multimedia, with the timer set shorter than the call drop timer. The user receiving the request is then prompted to accept or decline the request. If no response is received before expiration of the automatic response timer, the terminal or MSC automatically declines the request on behalf of the user so that the call drop timer does not expire.
摘要:
A system and method for using Mobility Management (MM) and Session Management (SM) procedures in an SAE/LTE system. The present invention modifies several MM and SM procedures that have been defined for other 3GPP access systems (such as GERAN, UTRAN) so that they meet the requirements of LTE/SAE. While the present invention re-uses some existing procedures, it further defines new protocols for MM and SM procedures when accessing 3GPP systems by Evolved UTRAN (EUTRAN). With respect to the new protocols, the encoding rules are re-used from the existing MM and SM procedures and a very similar general message format is created. With respect to the signaling messages, the present invention re-uses the existing information element definitions for each parameter included in a message.
摘要:
A temporary-identity-storage method for user equipment includes receiving authentication challenge information and at least one temporary identity, processing the authentication challenge information, and determining whether the processing step results in successful authentication. The user equipment includes mobile equipment and a subscriber identity module. Responsive to a determination that the authentication was successful, the received at least one temporary identity is considered to be valid. If the received at least one temporary identity is at least one pseudonym and an appropriate data file to the store the at least one pseudonym is available in the subscriber identity module, the at least one pseudonym is stored and any previously-stored pseudonym is over-written in the subscriber identity module. If the received at least one temporary identity is at least one pseudonym and an appropriate data file to the store the at least one pseudonym is not available in the subscriber identity module, the at least one pseudonym is stored and any previously-stored pseudonym is over-written in the mobile equipment. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

A method for selecting a public land mobile network (PLMN) from a plurality of available PLMNs more particularly, one embodiment of the invention includes the steps of transmitting, via a mobile network, information related to the plurality of available PLMNs. The method further includes the step of receiving, at a mobile station, the information related to the plurality of available PLMNs, and responsive to the step of receiving, sending, to the mobile network, of a Non-Access-Stratum (NAS) signaling message including an identification data for selecting one PLMN from the plurality of available PLMNs. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 CFR 1.72(b).

摘要:
A method, device management server, Packet Data Network Gateway (PDN GW) and User Equipment (UE) for establishing a PDN connection having defined packet flow limitations from a UE to a PDN GW. When a misbehaving or malicious UE is operating in the Evolved Packet System (EPS), the invention enables the UE to retain a PDN connection with an EPS bearer open until the software in the UE has been updated. The server sends to the UE, a management object that includes a logic parameter (packet filters) for controlling a packet flow from the UE to the network, or a defined Access Point Name (APN) that enables the UE to obtain the packet filters from a PDN GW. In turn, the UE sends to the network, a request for a new PDN connection while requesting deactivation of any previously existing PDN connections. The UE transmits on the new PDN connection, only packets allowed by the logic parameter.
摘要:
The method and apparatus described herein enables a mobile station to subscribe to a larger number of multi-cast services than provided by a conventional wireless network. According to one embodiment, the network establishes a multi-cast communication session and allocates a NSAPI to the communication session during a data transfer phase. Subsequently, the network transmits the multi-cast data during the established communication session. According to another exemplary embodiment, the network includes two non-overlapping value spaces, where one of the value spaces is reserved for multi-cast NSAPIs. In this embodiment, the network receives a NSAPI selected by the mobile station during the joining phase from this value space. During the data transmission phase, the network establishes a multi-cast communication session based on the selected NSAPI, and transmits the corresponding multi-cast data during the communication session.
