The present invention is directed to protocol compatibility, in particular. The present invention relates to an apparatus and a method for preventing a problem of processing a transmission message of a portable terminal in a network, which may occur when a protocol version of a network is lower than a protocol version of a portable terminal in a mobile communication system.

In the third generation mobile communication system (UMTS), new functions such as High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) are being implemented for higher competitiveness. Standardized through the 3 Generation Partnership Project. In 3GPP, the version of the specification is specified differently when many new features are applied. Currently, from R1996 to R1997, R1998, R1999, Rel4, Rel5, Rel6, Rel7, and Rel8, most operators have started using the R1999 version. Here, the version of the specification represents the protocol version.

Recently, as the market interest and demand for HSDPA increases, each service provider is preparing a terminal that supports and installs a network that supports Rel5 to supply a network and a terminal that supports HSDPA. The system information block (SIB) periodically transmitted by the network in the UMTS system broadcasts information on a specific cell and provides information to terminals camped in the specific cell. Current system information does not include protocol version information. Therefore, there is no way to inform the terminal of the protocol version supported by the network. In general, when the terminal supports Rel5, all messages are transmitted to the Rel5 version regardless of the protocol version supported by the network. This can sometimes cause problems in areas with non-upgraded networks. That is, if any node of the UMTS system is not upgraded to Rel5, there is a problem that a case in which the received message cannot be properly interpreted. In general, the UMTS system has backward compatibility, so a node supporting Rel5 can be processed even when an R1999 message is received, but a node supporting only R1999 cannot process a Rel5 message.

Since the terminal does not know which protocol version the network supports, the terminal supporting Rel5 assumes that the network can handle all Rel5 messages. Therefore, in order for a terminal supporting Rel5 to operate normally, all networks must be upgraded to Rel5. For example, a French S operator performed a network upgrade to release a Rel5 terminal supporting HSDPA, and there is a case where a call drop occurs in the region because the upgrade has not been completed. In the above case, even though the terminal is located in an area where the field is bad because the network fails to process the Rel5-related extension field in the message transmitted by the terminal performing a measurement report in the corresponding area, This is a case where call drop occurs frequently because the UE does not provide a handover service to the terminal.

In order to solve the compatibility problem according to the protocol version, the present invention includes a protocol version supported by the network in a system information block (SIB) and broadcasts it to the terminal to generate a message in accordance with the protocol version of the network in the terminal.

Referring to FIG. 1, in order to prevent a problem that may occur when a message is transmitted and received between a terminal that supports Rel5 and a network that is not upgraded to Rel5, an information element (IE) called "Release version indicator" in system information (SIB 5). This is a case of transmitting by adding: Information Element.

In step 110, the network device generates system information including an information element called a "Release version indicator" including a protocol version, that is, version information, and transmits the system information in step 120. The system information is broadcast information.

Referring to FIG. 2, in order to prevent a problem that may occur when a message is transmitted and received between a terminal that supports Rel5 and a network that has not been upgraded to Rel5, an information element called "Release version indicator" in system information (SIB 5). This is a description of the operation when (IE: Information Element) is received.

When camping in a specific cell, the UE acquires system information (SIB 5) through the P-CCPCH channel as in step 210. At this time, the terminal checks the protocol version of the network by obtaining a "Release version indicator" from the system information (SIB 5) in step 220.

When the protocol version of the network is a lower version (eg, Rel 5 or earlier) in step 220, the lower version of the protocol is used in step 230.

Alternatively, if the protocol version of the network is equal to or higher than the protocol version of the terminal in step 220, the current protocol version is maintained in step 240.

The terminal adaptively transmits and receives a message according to a protocol version of the network. Using this approach, you can avoid problems that prevent message handling due to differences in protocol versions.

Then, the algorithm according to the present invention is terminated.
