Accompanying drawing explanation
Fig. 1 is the configuration diagram of the communication network of the coexistence of systems of the different systems in the embodiment of the present invention.
Fig. 2 is that the terminal in the embodiment of the present invention is adhered to signaling process figure.
Fig. 3 carries switching flow figure between the data service net in the embodiment of the present invention.
Embodiment
The specific embodiment of the invention, take the communication network of the coexistence of systems of GSM, TD-SCDMA, TD-LTE and tetra-kinds of different systems of WLAN as example, is described in detail the specific embodiment of the present invention by reference to the accompanying drawings.
Fig. 1 is the configuration diagram of the communication network of the coexistence of systems of the different systems in the embodiment of the present invention.As shown in Figure 1, this communication network comprises 2G/3G core net and EPC (Evolved PacketCore, evolution block core net).The function of access controller AC, base station controller BSC and radio network controller (RNC) that network element SuPC (Supper Controller, super controller) in the embodiment of the present invention is integrated supports that between different system, adjacent area arranges simultaneously.
Terminal adhering to, first registration networking, position upgrade, under co-location update status, all will carry out information interaction with network.Fig. 2 is the signaling process figure that the terminal in the embodiment of the present invention is adhered to.As shown in Figure 2, this attachment flow comprises the following steps:
Terminal is initiated after data service normal, and network is differentiated four net abilities of terminal, then initiates to carry switching by network side.Fig. 3 carries switching flow figure between the data service net in the embodiment of the present invention.As shown in Figure 3, this flow process comprises the following steps:
Step 301, terminal (MS/UE) are initiated data service.
If step 303 Query Result is "Yes", VLR/MME sends " Load bearing Request " message to SuPC/eNode B, starts carrying and switches; If Query Result is "No", finish to carry switching flow.
If the objective network that step 304 carrying is switched is non-wlan network, SuPC/eNode B is according to the objective network of the Neighboring Cell List judgement carrying shunting of community, terminal place, send " TestingRequest " message to terminal, start terminal and carry out network detection.
In the above-described embodiments, terminal need be supported the system of four kinds of different systems.Terminal carrying out in data service process, is received after the network measure indication of network side, is carried out the measurement of signal strength signal intensity and interference strength according to the objective network configuration providing in message; After completing, measured value is reported in response message.
Terminal in data service process, is received after network side switch indicating information carrying out, is started to carry switching.Below point three kinds of different handoff scenario are described in detail the specific embodiment of the present invention.
1.GSM/TD-SCDMA/TD-LTE network switches to wlan network
Terminal is hung up ongoing business, and open wireless network interface card is also registered in wlan network.Success continues data service after registering in wlan network.After normal continuation business, in handover acknowledge message, reply " success ", and discharge the Radio Resource in former GSM network or TD-SCDMA network or TD-LTE network.If cannot normally continue data service after registering unsuccessful or registration, get back to former GSM network or TD-SCDMA network or TD-LTE network and continue data service, and reply " failure " in handover acknowledge message, report failure cause simultaneously.
2.GSM network switches to TD-SCDMA/TD-LTE network
Terminal is hung up ongoing business, switches to TD-SCDMA network or TD-LTE network according to switch indicating information.After handover success, in handover acknowledge message, reply " success ", and discharge the Radio Resource in former GSM network.If handoff failure, gets back to GSM network and continue data service, and reply " failure " in handover acknowledge message, report failure cause simultaneously.
3.TD-SCDMA network switches to TD-LTE network
Terminal is hung up ongoing business, switches to TD-LTE network according to switch indicating information.After handover success, in handover acknowledge message, reply " success ", and discharge the Radio Resource in former TD-SCDMA network.If handoff failure, gets back to TD-SCDMA network and continue data service, and reply " failure " in handover acknowledge message, report failure cause simultaneously.
SuPC, in possessing BSC, RNC and AC existing capability, can store many network neighbors ability.ENode B supports many network neighbors of storage ability.
The method that SuPC/eNode B side is carried out data service switching comprises:
Receive after network side load switching command, SuPC/eNode B initiates nearby region measurement instruction to terminal, and the priority orders of each network carrying data service is followed successively by from high to low:
WLAN＞TD-LTE＞TD-SCDMA＞GSM
The measurement of receiving terminal judges whether to switch according to the intensity of measured signal and interference strength after replying;
In the time switching, for terminal distribution objective network Radio Resource, instruct terminal to switch by switching command; If when objective network is WLAN, do not need Resources allocation;
After receiving that handover success is replied, discharge former Radio Resource;
After receiving that handoff failure is replied, discharge to draft and switch target network Radio Resource, if when objective network is WLAN, do not need releasing resource.
Four net ability CAMEL-Subscription-Information of VLR and MME storage terminal, initiate, in data service process, to judge after terminal four net ability CAMEL-Subscription-Information in terminal, send carrying switching command to SuPC or eNode B.
When SGSN and X-GW initiate data service in terminal, normal continuance terminal traffic, is notified to VLR/MME meanwhile, triggers VLR/MME and carries out terminal four net efficiency tests.
The CAMEL-Subscription-Information of the HLR shown in Fig. 1 and HSS storage terminal, wherein comprises four net ability parameters of terminal; In the renewal/co-location renewal process of register in terminal/position, four net ability parameters of terminal need to be sent to VLR/MME and store.
Trigger point and triggering method, decision method that in the specific embodiment of the invention, data service is switched are respectively:
When trigger point one: SGSN/S-GW finds that terminal is initiated data service, initiate " Capability indicator ", inquiry terminal four net abilities to VLR/MME; Triggering method: terminal is initiated data service;
Trigger point two: VLR/MME receives after SGSN/S-GW's " Capability indicator " reporting message, checks four net abilities of terminal, while finding that there is four net abilities, triggers to SuPC/eNode B and sends " Load bearing request "; Decision method: terminal four net ability CAMEL-Subscription-Information are "Yes";
Trigger point three: SuPC/eNode B receives after " Load bearing request ", triggers to terminal and sends " Testing Request "; Triggering method: receive " Testing Request " message;
Trigger point four: SuPC/eNode B receives " Testing Answer ", judges whether to switch, if be judged as "Yes", trigger to terminal and sends " Load handoff Command "; Decision method: the threshold value of switching according to the each network of data configuration;
Trigger point five: terminal is received after " Load handoff Command ", available data business is hung up, in objective network, initiate data service according to allocation of radio resources situation, after having switched/having stopped, report " Load handoff success/fault " to SuPC/eNode B; Decision method: handover success or failure.
Technical scheme of the present invention, due to by user's data service bearer network being adjusted and controlled by network side, realizes service bearer shunting between different system, thereby has optimized user's experience, has reduced carrier cost.
It should be noted that: above embodiment is only unrestricted in order to the present invention to be described, the present invention is also not limited in above-mentioned giving an example, and all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in claim scope of the present invention.
