Problems solved by technology

Triangular routing will increase latency, consume additional transmission bandwidth and processing power
However, this method makes the paging logic very complicated, and it is necessary to judge the range of AT movement to decide which mode to use, thus reducing the system efficiency

Embodiment 1

[0071] This embodiment describes the process in which the AGW assumes the function of buffering data, the SRNC triggers the AGW to start buffering data, the AGW triggers the SRNC to initiate paging, and establishes a new air interface connection and a new tunnel to transmit data.

[0072] see Figure 4 , is a schematic diagram of a paging process based on the UMB network architecture in Embodiment 1 of the present invention.

[0073] After the terminal is attached to the network, an air interface bearer is established with the source eBS, and a PMIP tunnel connection is established between the source eBS and the AGW. The AGW sends the user's downlink data to the DAP through the PMIP tunnel. DAP sends to the terminal to receive through FLSA (Forward Link Serving AN, forward link serving AN); the terminal sends the user's uplink data to RLSA (Reverse Link Serving AN, reverse link serving AN), and RLSA passes the data through PMIP tunnel sent to AGW. The DAP, RLSA, and RLSA ma...

Embodiment 2

[0085] This embodiment describes the process in which the AGW assumes the function of buffering data, the SRNC triggers the AGW to start buffering data, the AGW triggers the SRNC to initiate paging, and transmits data through the newly established air interface connection and the original tunnel.

[0086] see Figure 5 , is a schematic diagram of a paging process based on the UMB network architecture in Embodiment 2 of the present invention.

[0087] After the terminal is attached to the network, an air interface bearer is established with the source eBS, a PMIP tunnel connection is established between the source eBS and the AGW, and data is transmitted between the terminal and the AGW through the established connection. The process of the terminal entering the idle state and using the newly established air interface connection through network paging and the original tunnel to receive user data sent by the network is as follows:

[0088] Steps 1a-1b, the terminal releases the c...

Embodiment 3

[0101] This embodiment describes the process in which the AGW assumes the function of buffering data, the SRNC triggers the AGW to start buffering data, the AGW triggers the SRNC to initiate paging, and the eBS sends a tunnel binding message to trigger the AGW to send buffered data.

[0102] see Figure 6 , which is a schematic diagram of the paging process based on the UMB network architecture in Embodiment 3 of the present invention. The process is similar to the process in Embodiment 1, and the specific steps include:

[0103] Step 1-7, the same Figure 4 Steps 1-7 in: After the terminal enters the idle state, the SRNC notifies the AGW to cache the user data of the terminal, and when the AGW receives the user data of the terminal, it caches, and notifies the SRNC of the arrival of the data of the terminal, In this way, the SRNC is triggered to initiate paging of the terminal; after the terminal responds to the paging, the current serving eBS of the terminal sends the conne...

Abstract

The invention discloses a paging method, a wireless network controller and an access gateway used in a mobile communication system. The inventive method comprises the steps: the access gateway, based on an instruction of caching user data sent by the wireless network controller, receives the data of a designated user and then caches the data for the user, and simultaneously sends a data arrival notification message with a user identification to the wireless network controller; the wireless network controller pages the terminal corresponding to the user identification via a base station and sends an instruction message with the user's identification of transmitting the cached data to the access gateway after the paging arrives the terminal; and the access gateway receives the instruction message and then sends the cached data of the user corresponding to the user identification to the terminal where the user locates via the base station. The invention can reduce the signaling cost during the paging process, avoid the route of data transmission and reduce the network delay.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a paging method, a radio network controller and an access gateway in a mobile communication system. Background technique [0002] At present, the global wireless communication is showing the trend of mobility, broadband and IP. The development of broadband wireless access to mobility has brought direct competitive pressure to mobile communication technology. Therefore, the two third-generation mobile communication standardization organizations, 3GPP and 3GPP2, successively started the technical research and standardization work of the evolved 3G system (E3G), in order to maintain the competitiveness of 3G technology and the leading position in the field of mobile communication. [0003] The evolution of the air interface of 3GPP2 is divided into Phase1 and Phase2. Phase1 completes multi-carrier HRPD (HRPD-High Rate Packet Data, high-speed packet data) or NxEV-DO. The main goa...
