However, this is very unreliable since the exact location of the UE within the range of the E-UTRAN cell is not known, and also due to the fact that the E-UTRAN cell (eg, 2600MHz) is compared different propagation characteristics

no. 1 approach

[0157] First Embodiment: A method for using a GSM / UMTS mobile communication network via a user equipment (20) connected to an Evolved Packet System (EPS) mobile communication network core network (10), wherein the GSM / UMTS mobile communication network Consumption is the result of a fallback operation in which at least one of the following steps occurs prior to the service request triggering the fallback operation:

[0158] - perform an update operation regarding the allocation of Location Area Code (LAC) and / or Serving Mobile Switching Center (MSC) to UE, the update operation being an additional TAU (Tracking Area Update) operation or a modified TAU operation or dedicated operation of the , and / or

[0159] - Perform measurement operations on the current GERAN / UTRAN radio environment of the User Equipment (20).

no. 2 approach

[0160] Second embodiment: The method according to the first embodiment, wherein, in case the user equipment (20) is connected to an Evolved Packet System (EPS) and a GSM / UMTS mobile communication network, performing an operation concerning the user equipment (20) Measurement operations for the current GERAN / UTRAN radio environment.

no. 3 approach

[0161] Third embodiment: The method according to one of the preceding embodiments, wherein the execution of the updating operation depends on at least one of the following:

[0162] - an update operation with a reduced repetition period compared to a TAU operation using the timer 3412,

[0163] - perform an update operation in case of a change of the serving E-UTRAN unit,

[0164] - perform the update operation after a maximum period of time after the last update operation or after the last change of the user equipment (20) from the start mode to the idle mode,

[0165] - perform an update operation based on a request from the core network (10),

[0166] - performing an update operation in case the UE (20) detects movement of the UE (20),

[0167] - Perform an update operation in case the UE (20) detects that a candidate target GERAN / UTRAN unit for fallback operations belongs to a different location area than the unit currently assigned to the UE (20).

Abstract

A method for use of a Global System of Mobile Communication (GSM) and Universal Mobile Telecommunication System (UMTS) (GSM / UMTS) mobile communication network by a user equipment attached to a core network of an Evolved Packet System (EPS) mobile communication network, the use of the GSM / UMTS mobile communication network being the result of a fallback operation, includes, prior to an invocation of a service that triggers the fallback operation: performing an updating operation regarding assignment of a Location Area Code (LAC) and / or a serving Mobile Switching Center (MSC) to the user equipment; and / or performing, autonomously by the user equipment, a measurement operation regarding a current General Packet Radio System (GPRS) / EDGE Radio Access Network (GERAN) or UMTS Terrestrial Radio Access Network (UTRAN) (GERAN / UTRAN) radio environment in order to identify potential CSFB target cells of the user equipment.

Description

Background technique [0001] The invention relates to a method of using a GSM / UMTS mobile communication network, in particular by a user equipment connected to a core network of an Evolved Packet System (EPS) mobile communication network. [0002] The 3rd Generation Partnership Project (3GPP) has specific capabilities for Evolved Packet System (EPS) networks and devices to allow them to use legacy circuits provided by Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) networks Exchange (CS) service. [0003] The motivation for this feature is that Circuit Switched (CS) services, such as voice and SMS services today, are not available on Evolved Packet System (EPS), since Evolved Packet System (EPS) only provides Packet Switched (PS) services fact. [0004] Therefore, there is a need for functionality that allows an Evolved Packet System (EPS) terminal - when it is registered in the Evolved Packet System (EPS) - when there is no...
