A core network entity includes a core network entity processing circuit. The core network entity processing circuit calculates a plurality of dormancy timer adjustment parameters in response to a received service request from a user equipment, and adjusts a dormancy timer for the user equipment based on (i) at least one load condition for the wireless network, and (ii) a comparison between each of the plurality of dormancy timer adjustment parameters and a corresponding one of a plurality of dormancy timer adjustment parameter threshold values. The core network entity then outputs the adjusted dormancy timer to a base station serving the user equipment.

Methods and systems for improving paging efficiency of a user equipment method including obtaining a history of the user equipment, the history including one or more past locations of the user equipment, obtaining a mobility pattern of the user equipment, the mobility pattern including one or more of a plurality of mobility categories, determining a confidence level for an associated location of the user equipment based on at least one of the mobility pattern and the history, the confidence level indicating a level of confidence that the user equipment is at the associated location, and deriving a paging range based on the confidence level, the paging range including one of a plurality of paging scopes, each of the plurality of paging scopes including at least one of a geographic or location extent, a paging frequency, a single node, a plurality of nodes, a tracking area and a plurality of tracking areas.

Adaptive paging using user equipment localization method in a network

A method is provided for passing information through a network during overload and subsequent actions to reduce congestion. An exemplary method includes receiving an origination request from a mobile device of a calling party, detecting an overload condition, transmitting a message request to a terminating network element associated with a called party in response to the origination request during the overload condition, receiving an acknowledgement of receipt of the message request, and denying the origination request. In this manner, high resource requests (e.g. a voice call) may be converted into lower resource requests (e.g. text or voicemail messages), or the resource request may be deferred to a more appropriate time.

Method and system for passing information through a network during overload

Various methods and devices are provided to address the need to mitigate the effects of an overload and/or prevent an overload from cascading. In one method, devices are paged () according to a first paging policy regarding paging attempts. It is then determined () that a reduced availability condition exists for network equipment supporting the first paging policy. While this reduced availability condition exists, user equipment is paged () according to an adapted paging policy which is more limited in paging attempts than the first paging policy.

Systems and methods are disclosed for transmitting a text/multimedia message over a bearer interface of a mobile network. A first network element of the mobile network, such as an MSC for a Mobile Terminated (MT) text/multimedia message or a BSS for a Mobile Originated (MO) text/multimedia message, receives a text/multimedia message. The first network element communicates with a second network element of the mobile network using a signaling interface (e.g., an IOS A1 interface) to select a bearer connection on a non-voice circuit-mode bearer interface (e.g., an IOS A5 interface), and routes the text/multimedia message to the second network element over the selected connection on the non-voice circuit-mode bearer interface. The first network element may also select a bearer connection on a voice bearer interface (e.g., an IOS A2 interface) and route the text/multimedia message to the second network element over the selected bearer connection.

Transmission of text/multimedia messages over bearer connections

Generalized Processor Sharing (GPS) is a scheduling discipline which provides minimum service guarantees as well as fair resource sharing. The performance of GPS is governed by the scheduling weights associated with individual connections. The system discloses methods for GPS scheduling that handle an arbitrary number of connection classes and reservation-based weights and admission control techniques to achieve fairness among connection classes. The methods allow statistical multiplexing gains in the presence of multiple traffic and Quality of Service (QoS) classes of connections that share a common trunk. Also disclosed are several novel techniques to compute and adapt the weights.
