Abstract

A data communication method, a communication system, and related devices are configured to establish a transaction identifier (TI) in a user equipment (UE). The data communication method includes the following steps. A mobility management entity (MME) receives a request message and obtains ability information of the UE. If the UE has an ability to access a Universal Terrestrial Radio Access Network/GSM/EDGE Radio Access Network (UTRAN/GERAN), the MME generates the TI. A communication system and related devices are also provided. Thus, the TI is effectively established in the UE, so as to ensure normal processing of the UE.

Claims

1. A user apparatus for data communication, comprising:

a transmitter;

a receiver;

a processor configured to;

send, via the transmitter a request message to a mobility management entity (MME) of a long term evolution (LTE) network, wherein the request message comprises ability information of the user apparatus indicating whether the user apparatus has an ability to access one of a Universal Terrestrial Radio Access Network (UTRAN) and a GSM/EDGE Radio Access Network (GERAN);

receive, via the receiver, a transaction identifier (TI), wherein the TI is generated based on the ability information of the user apparatus by the MME and for a bearer identifier of the user apparatus in the LTE network;

communicate, via the receiver and the transmitter, with the LTE network to leave the LTE network; and

perform an access procedure to access, via the receiver and the transmitter, the one of the UTRAN and the GERAN by using the TI.

2. The user apparatus of claim 1, wherein the request message comprises one of the following:

an Attach Request message initiated by the user apparatus,

a Packet Data Network Connectivity Request message initiated by the user apparatus,

a Dedicated Bearer Request message initiated by a Packet Data Network Gateway (PGW), and

a Resource Allocating Request message initiated by the user apparatus.
