Embodiment 3

[0053] Such as figure 1 As shown, in the method for obtaining the identity of a different system cell described in the third embodiment, the following steps are included:

[0054] Step 21, the mobile terminal in the packet transmission mode in the GERAN network sends a request message to the BSS to read the system information of the cell of the different system through the uplink control channel. And, during this period of time, the BSS does not send downlink packet data to the mobile terminal any more. The time required for the mobile terminal to read the system information may be included in the request message for reading the system information of the cell of the different system, or the time required for the mobile terminal to read the system information may be set as a default value.

[0055] Step 22: After receiving the reading request message, the BSS may send a system message reading response message to the mobile terminal, or may not send a system message reading res...

Embodiment 4

[0060] In the method for obtaining the identity of a cell of a different system described in Embodiment 4, if figure 2 shown, including the following steps:

[0061] Step 31, the mobile terminal in the packet transmission mode in the GERAN network sends a request message for reading the system information of the cell of the different system to the BSS through the uplink control channel. And, during this period of time, the BSS does not send downlink packet data to the mobile terminal any more. Different from that in the second embodiment, the time required for the mobile terminal to read the system information is not included in the request message for reading the system information of the cell of the different system.

[0062] Step 32: After receiving the request message for reading the system information of the different-system cell, the BSS sends a system information reading response message to the mobile terminal, or does not send a system information reading response me...

Embodiment 6

[0070] Such as image 3 As shown, in the method for obtaining the identity of a different-system cell described in Embodiment 6, the following steps are included:

[0071] Step 41: The mobile terminal in the packet transmission mode in the GERAN network sends a request message to the BSS to read the system information of the cell of the different system through the uplink control channel, and requests the BSS to allocate an available time for reading the system information.

[0072] Through the request message for reading the system information of a different system cell, the mobile terminal will tell the BSS the time required to read the system information of an E-UTRAN macro cell or CSG cell, and may also inform the E-UTRAN macro cell to be read Or tell the BSS the number of CSG cells, or set the time required to read an E-UTRAN macro cell or CSG cell system message as a fixed value, without the mobile terminal reporting to the BSS.

[0073] Step 42: After receiving the req...

Abstract

The embodiment of the invention discloses a method, a device and a system for acquiring a cell identifier of a special system, relates to the technical field of communication and aims to realize correct measurement of an E-UTRAN macro cell or a CSG cell on the premise of ensuring minimum data loss rate or no data loss rate in a process when a E-UTRAN cell seamlessly moves towards the E-UTRAN macro cell or the CSG cell. The method comprises the following steps: in a packet transmission mode, transmitting a request message for reading cell system information of the special system to a GSM / EDGE wireless access network entity; and modulating the frequency to an evolved UMTS wireless access network macro cell or a user group cell for a group, reading the system information and acquiring the cell identifier of the special system. The embodiment of the system is mainly applied to techniques of cell measurement and the like.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device and system for acquiring cell identifiers of different systems. Background technique [0002] With the development of communication technology, the coverage of GERAN network (GSM / EDGE Radio Access Network, GSM / EDGE wireless access network) is getting wider and wider, and can meet the requirements of voice service and low-speed data service. In order to meet the high data transmission rate requirements of users' new services, it is necessary to deploy E-UTRA network (Evolved UMTS Radio Access Network, evolved UMTS radio access network) and Home NodeB (home base station) in the traditional GERAN network. The cell formed by the home base station is called a CSG (Closed Subscriber Group, group subscriber group) cell. [0003] In order to realize seamless mobility from a GERAN cell to an E-UTRAN macro cell or CSG cell, a mobile terminal in packet...
